Q:In the transformer load calculation to be calculated when the fire pump
Calculated in two states, the normal state and fire status. Normal does not calculate the capacity of fire equipment, such as fire pumps, fire engines and so on.
Q:KW how to know how much transformer?
Know the number of KW, how to calculate how much transformer is needed. In general, our calculation is based on the nature of the equipment, the production process, the development prospects of the production enterprises to analyze the size of the transformer, some companies, how many kilowatts to choose the number of KVA, and some enterprises have all the equipment must boot Run, then, on the choice of a little bigger, the machinery industry enterprises, generally in accordance with the installed capacity of 4-5 fold to select the transformer capacity. For reference only.
Q:What is the use of the lower part of the transformer made of rail?
This approach facilitates the handling and installation of the transformer, but due to the large and larger transformers, the use of wheels is already less. Transformer The lower part of the box has two structures: (1) Set the wheels, which requires the installation of the track on the basis of the transformer, and then the wheels fixed on the I-beam track, this way to facilitate the maintenance and installation of the transformer handling, but because of the large and larger transformers, the use of wheels Has been less; (2) set I-beam or channel as a load-bearing beam. This transformer does not need to set the track, on the basis of the transformer relative to the location of the beam weighing embedded flat steel, the transformer in place after the load-bearing beam fixed fixed on the base embedded parts. Need to move the transformer, the chisel spot welding, with the hoist and other machinery will slowly drag the transformer.
Q:What is a transformer paused?
3. If the user fails to apply for the resumption of electricity, the power supply enterprise shall, from the date of expiry date, calculate the basic electricity bill according to the capacity stipulated in the contract; 4. During the period of suspension, the user shall apply to the power supply enterprise five days before the scheduled restoration date when the user applies for the resumption of the suspension of electricity consumption. The suspension time is less than fifteen days, the suspension of the basic electricity charges during the period;
Q:Transformers are divided into several. What is the role of each? To be specific!
(Ii) Classification by purpose Transformers according to their use can be divided into power transformers, audio transformers, pulse transformers, constant voltage transformers, coupling transformers, autotransformers, isolation transformers and other. (C) according to the core (or core) shape classification Transformers according to the core (core) shape can be divided into "E" type transformers, "C" type transformers and ring transformers.
Q:Transformer oil filter method
So only on-line oil treatment. Oil filters require an external oil filter and oil tank. The new oil (has been qualified, insulation pressure are qualified oil into a clean oil tank inside, the external oil filter and oil drums and transformer tubing as a whole, the external circulation of online filter oil). Mainly: 1, online filter to continuous operation, to ensure that the weather is fine air humidity less case, under the conditions of the best conditions for 214 hours of continuous operation.
Q:How is the insulation of the transformer divided?
Insulation can be divided into two parts: main insulation and vertical insulation. The main insulation is between the winding and the ground part, and the insulation between the windings.
Q:Which transformers belong to special transformers
These special-purpose transformers are known as special transformers. Because of the working conditions and load conditions of these transformers, they can not be calculated by the general transformer calculation method.
Q:Why is the transformer coil insulation?
Insulation grade refers to the heat resistance of the insulation material used, divided into A, E, B, F, H grade. Allowable temperature rise is the limit of the temperature of the motor compared to the ambient temperature. Insulation temperature Class A Class E Class B Class F Class H Maximum allowable temperature (° C) 105 120 130 155 180 Winding temperature limit (K) 60 75 80 100 125 Performance reference temperature (° C) 80 95 100 120 145 Generators and other electrical equipment, the insulation material is the most weak link. Insulation material is particularly susceptible to high temperature and accelerated aging and damage. Different insulation materials have different heat resistance, the use of different insulation materials, electrical equipment, the ability to withstand high temperatures are different. So the general electrical equipment is specified in the maximum temperature of its work. According to the different insulation materials to withstand the high temperature of its ability to set the maximum allowable temperature of seven, according to the temperature size were: Y, A, E, B, F, H and C. Their allowable operating temperatures are: 90,105,120,130,155,180 and 180 ℃ above. Therefore, Class B insulation indicates that the insulation temperature of the generator used is 130 ° C. The user should ensure that the generator insulation does not exceed the temperature during operation of the generator to ensure proper operation of the generator. Insulation class for the B-class insulation material, mainly by the mica, asbestos, glass fiber by the organic glue or impregnated from. Commonly used B-class insulation materials are PVC glass fiber casing (yellow wax tube), 6520 composite paper, DMD insulation paper.
Q:Transformer noise reduction
Transformer noise is mainly caused by magnetostriction of silicon steel sheet. method: 1, choose a reasonable magnetic density; 2, core clamping; 3, pad to take shock measures; 4, the tank within the parts fastening, does not allow loose metal parts or standard; 5, all the accessories on the tank must be tightened; 6, the use of low noise fan; 7, the installation of the basic level. Dry-type transformers do not have fuel tanks, remove the other 5, the same, because the dry-type transformers do not have the mailbox, the core magnetic choice, parts fastening, installation foundation leveling is more important
