Q: What transformer can be used in a safety voltage lighting transformer?: Early European countries used in the power industry, widely used in the electronic industry or industrial and mining enterprises, machine tools and machinery equipment general circuit control power supply, safety lighting and indicator light power supply.

Q: How many can you bring with 220V? How many can you bring with 380V? There are 3 terminals on the transformer. There are 220V, 380V, 0, three terminals. 220V is the 220V terminal and the 0 connection. How can the 380V be connected? Is it 380V and 0 or 380V and 220V?: Connect 220V method, FireWire 220V terminal, zero line 0 terminal, 380V terminal is not connected.Connect 380V method, A phase 380V terminal, B phase 0 terminal, 220V terminal is not connected.

Q: The difference between lighting transformers and control transformers: Lighting transformer voltage is generally rated by a group or two setsControl transformers have many levels of output voltage

Q: Is the substation separate from the power and illumination transformer?: The power and illumination of the substation are all used on a transformer, which is separated by power and lighting by the station screen of this transformer.

Q: The transformer zero line has broken, has the result to the household illumination circuit?: The power supply system in three-phase four line zero line is broken, the breakpoint of the single-phase circuit (220V) electrical burn by voltage to 380V. I met, the incandescent lamp suddenly particularly bright then the blow up of internal fuse TV has burned out. So in the three-phase four wire power supply system zero line asked to do repeat grounding in households is the reason.

Q: How many A leakage protection switches are used in 5000VA lighting transformers?: AC circuit transformer for lighting lamp is suitable for 50-60Hz, is the power supply with safety shell low-voltage safety lights, can choose 220V or 380V power supply input voltage: 0V, 220V, 380V, 0V, 6.3V, output voltage: 12V, 24V, 36V.

Q: Does the lighting work properly? Doesn't that power equipment start voltage unstable?: It is not easy to control, the power and lighting and electricity; if the transformer capacity is small, and relatively large power equipment start frequently, voltage stability will be poor, the lamp brightness will fluctuate dramatically, have effect on visual acuity. But as long as the design is reasonable, it has little effect.

Q: Why can't autotransformer be used as transformer for safety lighting?: The main and auxiliary coils of the autotransformer have common parts. Once the short-circuit is made, the lighting circuit is directly connected with the high voltage circuit, which is very dangerous

Q: What's the function of the lighting transformer?: Illumination transformer: usually refers to the secondary output voltage for the safety voltage 24V - 36V, only for special lighting power supply using voltage converter.

Q: 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=34.76A
