Q: Why should lighting transformers be used in factories and mines?: In some factories and mines (such as power plants), in order to supply power reliability, the power system is grounded in a three-phase, ungrounded, or neutral manner. In this way, the transformer must be connected to a neutral grounding type with a special transformer to supply power to the lighting.

Q: Why is the two side of the lighting transformer grounded?: Neutral grounding of three-phase transformer is called working earthing: the main function is to strengthen the stability of low-voltage system potential, and to reduce the risk of overvoltage caused by grounding, high voltage, short circuit, etc..

Q: The difference between lighting transformers and control transformers: The lighting voltage is 36 and 12V, the signal lamp is 6V, the control winding is 127, 110V, the one or two insulation, and the two one is grounded.Simple lighting transformers, the two voltage is not so diverse.

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: Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40: I don't know how much the output voltage of your transformer is, but the internationally accepted voltage below 36V is the voltage that is not harmful to the human body

Q: Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.: Double winding type safety isolating transformer load end and the power supply terminal is not connected, is safe, and autotransformer primary winding of a share, it is directly connected with the power supply end of the power, not safety.

Q: Power and lighting transformers, lighting quality will be affected much?: The bulb adopts a luminous two stage tube combined lamp holder, and the calculation process is very complicated. The secondary voltage is different in different combinations. Because it is a direct current ignition, but also consider the efficiency of its rectifier, but the total power is unchanged.

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

Q: Lighting, lights, transformers, bulb brightness is too low, what's the matter?: If you share a power line, you must calculate the current and select the appropriate wire to ensure normal pressure drop and safe use.

Q: How to calculate the rated capacity of small transformers for lighting purposes?: But in fact, consider the total load, the importance, the location of the machine, and the future additional plan, according to the following order.
