Intelligent PLC TransformerFan Control Box
Intelligent PLC Control Box forTransformer Fan is a new type intelligent transformer temperature controldevice equipped with Siemens S7200 PLC as the control center, has powerfulcontrol function, clear and concise wirings inside, and easy to operate andmaintain.
Traditional control box for transformer fans adopts time relay, motorprotector and etc to form required input and output signals, and achieves thecontrol function of fans by a combination of time relay and open-close contactpoint. This traditional control method is limited by the scope of timeadjustment, has lower accuracy of time adjusting, inflexible control logic, andcomplex electrical logic circuit, it is difficult to change and maintain infuture.
After using PLC as the control center, the simulating volume collectsthe temperature values from the temperature sensor of transformer, the fan canbe controlled to switch on/off by the output points of switching volume of PLCprogram control in accordance with the temperature range in PLC, the originalmechanical type time relay has replaced by the Timer in the PLC; the alarmcontact points of fan protector is also connected to the input port of PLCswitching quantities and is directly monitored by the PLC to protect all fans.
Even more importantly, PLC control system can control the fan oftransformer to rotate at regular time in accordance with the internal tuningtime, which not only meet air-cooling, but also effectively extend the fan’sservice life, and significantly reduce the operation failure rate of the fan.
PLC free port is made into 485 port, which follows the normal MODBUS agreementand can be used as RTU (Remote Transmission Unit) for the power system"four remote" control.
Structure
The product is composed of Siemens S7200 PLC (CPU+ module of simulatingvolume), intermediate relay, motor protector, temperature sensor, temperaturedisplay meter with signal output, housing and etc.

- Q: could an electrical engineer work in mechanical engineering?
- That can depend on where the engineer is working and what their work history is. In the company where I worked there was an electrical engineer who was considered an expert in all types of rotating equipment from pumps to compressors to turbines. He was also considered an expert in piping, pressure vessels and heat exchangers. All areas typically considered areas covered by mechanical engineers.
- Q: Ever since I was a little kid I could tell when there is a T.V on in a house when I walk by. I get this feeling inside like I can sense the signal or something with my brain. When I walk closer to the T.V the feeling gets stronger. If there is a T.V left on in my house with no sound or picture playing, I am still able to sense that the T.V was left on, and pinpoint the exact room its in without even going inside. Does this happen to anyone else?
- Yep, I can too. CRT tvs have a flyback transformer that operates around 15kHz - near the top end of human hearing. Other electronic devices using switchmode power supplies may also generate similar frequencies. I can also sense wifi hotspots - my eyes get tired and itchy like a summer day without sunglasses - the RF tends to dry them out.
- Q: Greetings, I've noticed that my electrical power company is constantly sending me a reports on how much electricity I am using with respect to my neighbors, kind of trying to get me to use less energy. I figured that if a company is in the business of selling something, it might as well encourage you to use more than you really need.Why is my utility encouraging me to use less electricity? Is it because they feel there's going to be a backlash against the industry once the word gets out that utilities are big drivers of global warming, and they are trying to do damage control ahead of time.Remember, we live in a capitalistic society where maximizing profit is key to keeping investors happy. I can understand the water company asking me to consume less water, as water is a scarce resource. Coalwe have lots and lots of it. Enough to burn for a few hundred years.
- Correct, revenue - expenses profit Building more plants or buying from other utilities is an expense. So, pretend that you are the electric company. Let's call it Jose Electric Company, JEC. So, JEC has to provide electricity to 5 million customers. They use about 1,000 kilowatt hours each per month. That comes up to 5,000,000 customers times 1,000 kw 5 billion kw-hours. If you could get them to cut usage then you would not have to build more power plants. Power plants used to be expensive, now they are very expensive. Your friend, the govt, does not want you to build plants that use coal. They are not keen on other fossil fuels. This year they like solar and portable nuclear plants. Yes, portable nuke plants. Till the political and regulatory environment gets a little more stable, it is easier to cut demand rather than build more production. On the other hand. Notice that within the last couple of weeks that 2 new nuke plants announced their start of new reactors. Looks like 1 was in South Carolina and 1 was in Georgia. It would seem that they have foresight, experience, skills, management and money to make sure supply is there for the demand. We also have enough natural gas to burn in jet driven turbines, many years. Water scarce? Where did the water go? Did it leave the planet? Water problems are logistics and not really shortages, are they?
- Q: I want to open a electrical contracting business down in Brisbane or Sydney after i have done my apprenticeship and had a thew years of experience I'm 16(Australia).Possibly even higher a thew lecky and also sell stuff like inverters etc. electrical equipment.The business would service the commercial side more then the domestic side.would this be a viable business or not.and would it be possible to make any money out of this to look after my family and look after my own family. Perhaps a couple hundred thousand a yearor would it be better to just go to the mines By the way i do study business organization and management plus economics so i have a general idea of what would be required like a very detailed business plan etc.
- Umm, someone that earns more than 400,000 is more than just wealthy, and I don't know if just being an electrician is enough. My father is an electrician, and his business is doing very well here in Adelaide (which would be very different than in Sydney). He just keeps on expanding, and I should probably mention that he never had any business training and he never went to uni or anything like that, but he did run another successful business when he was younger. But don't get me wrong, it is great to have that knowledge, it will only make things better. But if its just money you are after, and don't mind the working conditions, I think mining is the better options.
- Q: hey yahoos , i just graduated this december on the 22nd with a degree in Electrical and Computer engineering . Apart from the fact that i graduated with a decent gpa ( not that great ) i have no idea why i chose that major or what kind of a job i should be looking for . I didn't have an internship , because of the pressure i was getting from my family which cooked my brain , and i'd rather Not do anything due to pressure than do Anything on my own. I have lost 75% of my motivation already and currently my only motivation is to buy some nice Gadgets, other than that , i don't know :( . , i was wondering if anyone could just advice me anything as if to what kind of a job should i be looking for in this field. What does it even mean by the term junior engineer. , Does anyone know if it's any good to learn 80% of electrical stuff and 20% of computer stuff. Is there a job market for that ? i am looking for a job in new york city itself . i don't have any more characters .:-(

- Q: I need to know what object or whatever uses light energy that then leads onto electrical energy that then leads onto kinetic energy in order to work, what equipment does that? I said a Solar powered calculator but it was wrong so i'm really confused, could anyone help?:/
- I think the simple example is: When Light incidence to the photo cells(Viz: photo transistor or diode biased by this incidence of light), photo electric effect occurs-----Due to photo electric effect, photo transistor or diode produces eclectic current(i.e electrical energy) -----This photo transistor/diode acts like a driver of the audio oscillator and triggers the power audio oscillator------then produces audio frequency of specific or variable frequency according to the design----this audio oscillator frequency/ies signal hooked (interfaced) to the matched loudspeaker------Now we hear the sound which is a mechanical energy. I think this is one simple example for your question. Thank you. [You will find above:the conversion like this: Light energy--Electrical energy ----mechanical energy].
- Q: I have to declare a major soon, I am in the general engineering program at my school. And I am stuck between chemical and electrical. I love math, physics and chemistry, and have come trhough computer programming unharmed. I intend on going to graduate school when I am finished my bachelors, and in my career I want to be involved in research and development. basically, I would like to work in a lab/ at a desk and design and test new equipment, products etc. Also, I am NOT a hands-on, put on an over-all and crawl around in a factory type of person.What major do you think could best help me further my ambitions? Also, if I pick one, say chemical engineering, would it be easiy to get into grad school in another engineering discipline, such as electrical engineering?4 seconds ago - 3 days left to answer.

- DUDE y go 2 shcool wen u coud chill with ur frends. thats wat I do and i am smarter then hell. peace on earth man!
- Q: I am about to finish my BS in Electrical Engineering and was considering getting a MS in EE but considering how the economoy is and the fact that the Bureau of Labor Statistics say it should grow slower than average. This being said what do you guys think is the most prudent thing to do in my case. Go for an MS Engineering Degree or start out with another degree maybe in healthcare.
- I agree with Bimmer, if you decide to stay in school, go for the MS in EE But MS can be quite different from BS. more pure math. and mainly RD, papers , thesis if you like sort of work go for it. Otherwise, go find a job There is a lot of job that are not advertisedespecially in EE.
- Q: Do you find batteries die faster than they should, light bulbs flicker or go out too quickly, electrical equipment does werid stuff or dies sooner than it should. I've had some weird experiences with the computer and one small printer ar work. Also, I had a period where remote controled TV's would go on by themselves. I don't have that problem now, though.
- there is alot that god will do to help people belive somthing if thats truely what they want to blive i belive if a shirital being is still omn earth other than Gods angles that will never give people supernatual powers i think thant evel can give others pwoers to tell the fucture to do the imposible suck as wich craft God said he would not saport wich craft becousr the evel ones are the ones that give the flesh the powers anf if you belive you have the powers tp do somting enough i think sata will give it to you in away that gives you power that you belive is your own ang will drive you away from God im sorry if you dont belive in God i dont want to push ant thing on to you eather way this it just my beliefe and if the electriity in ones body is chaneled difrent then other its eather that or couse were created difrent then others and its afact every one has a eletric charch that keeps them alive ive never exped this but i belive some have i cant say waether its a gift from satan or how God created you mabe somthing you were exposed to or a defect in the geans when you were born mabe a posative afevct and mabe taking in the eletricity is what keeps some one alive becouse the produce normaly less charge than there body needs its somthin that one day will be studied as it becomes more comon as all thing do or they just die out like spontanios cumbustion did eather so rare it is not studird or just a mith or somthing that is of the past this is just an opinion i have never herd of this but i do know that eletricity is a major part of hat amd mind function and existed sence the begining of the earth and space and was not nvented but descovered i hope this helped feel free to contact me id love to talk futher and here about you experinces thank you and have a nice day
- Q: And what is an MBA? My sweetie is studying that at a community college will that mean he won't learn as much as if he took it in university?
- An EE learns the principles of electricity and puts them into practice. He designs and builds things that use electricity, like an electric power plant. MBA is Masters of Business Administration degree. Community college does not have as much prestige as elite universities. His learning depends on his ability and willingness to work.
