How many A leakage protection switches are used in 5000VA lighting transformers?
- It is widely used in the electronic industry or industrial and mining enterprises, in the machine tool and the mechanical equipment, the control power of the general electric circuit, the use of the power supply of the safety lighting indicator lamp.s
How is the lighting power of the 380V transformer calculated?
- Special transformer power transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, transformer, audio, mine variable frequency transformers, high frequency transformer, transformer, instrument transformer, impact power transformer, reactor, mutual inductor etc.) circuit with T symbol number. For example: T01, T201 etc.s
Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design
- Pe=19.5KW, installed capacityKx=1 coefficient of demandPjs=KxPe=19.5KW, calculated loadCOS, phi, =0.85, power factorIjs=KxPe/3/220/cos phi (Ijs calculates current, voltage, 380V/220V, three-phase)=1*19.5*1000/3/220/0.85=34.76As
Why should lighting transformers be used in factories and mines?
- But in many cases, such as mines and machinery, the voltage is too high and unsafe. The lighting transformer is then used to reduce the voltage to the so-called "safety voltage""s
What's the function of the lighting transformer?
- Applies to some requirements for safe voltage 24V - 36V lighting sites. Such as: basement, tunnel, dangerous goods warehouse and so on. Then there is the (mobile, temporary) safety lighting for the overhaul.s
Can the 500 volt lighting transformer be changed into an electric welder?
- The structure of the electric welding machine is different from that of the transformer, and the magnetic gap of the iron core can be adjusted so that the welding current can be changed. In addition, the output voltage of the welder is also softs
Our power lines and lighting lines are connected to the same transformer. Is there any effect?
- The transformer that power supply company manages, it is to supply motive power and illumination generally, namely the lighting transformer that does not have special illumination to illuminate. Units of their own transformers, is generally the case. The utility model has the advantages that the transformer and other equipment can be fully utilized, the efficiency is high, and the external power supply circuit does not need to be divided into power transmission lines and lighting circuits, and is simple and orderly, and the cost is low. As for the price of electricity, it is usually negotiated a power and lighting each percentage of the electricity to calculate and receive.s
