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: Why is the two side of the lighting transformer grounded?: In the three-phase transformer, the neutral point of the three-phase transformer and the metal case are always reliably connected, and the utility model has the advantages of reliable grounding, both working grounding, protection and earthing, and protection of personal safety and equipment safety.

Q: Why is elevator lighting transformer installed?: 3 a power outlet shall be provided at the bottom pit.4 the cables and wires laid in the hoistway shall be flame retardant and damp resistant, and shall be protected by a nonflammable wire, conduit, or wire slot, with no use of wires, conduits, or wire slots made of combustible material.5 an elevator attached to a building whose wiring, materials and methods and electrical components used shall take into account the effects of climatic conditions and shall take waterproof measures.Lighting transformers in order to obtain 36V voltage

Q: Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40: What you think? Your light is 220V, right. Over 36V, it's better not to live with electricity unless there is good protection

Q: How many A leakage protection switches are used in 5000VA lighting transformers?: According to the working principle of the protector, it can be divided into three kinds: voltage type, current type and pulse type. The voltage protection device is connected to the transformer neutral point and the ground, when the electric shock when the neutral point voltage offset to the real estate, in order to make the action to protect the power off, but because it is the protection of the transformer low voltage network, cannot be classified protection, so the power range is large, frequent moves, so has been eliminated. The pulse current protector is a sudden change in the phase and amplitude of the three-phase unbalanced leakage current when an electric shock occurs, which is used as an action signal, but also a dead time. The current type current leakage protector is widely used, so the protector of current type is mainly introduced below.

Q: How is the lighting power of the 380V transformer calculated?: The transformer (Transformer) principle should change the AC voltage of the primary coil, the main component of the device level by using electromagnetic coil core (core) main functions: voltage transformation, current transformer, impedance converter, isolation, voltage regulator

Q: Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.: So, safety regulations: lighting transformer must double winding type safety isolating transformer, prohibited the use of autotransformer.

Q: Power and lighting transformers, lighting quality will be affected much?: Corresponding to the transformer power supply, in order to save costs and reduce costs, the choice of AC ignition method is better. Pure resistive load, the power factor is 1. The 3 *100W=300W is the capacity of the required transformer

Q: Why can't autotransformer be used as transformer for safety lighting?: The transformer of the lighting circuit is a step-down transformer (general input 10kv., 220V). The first coil of the autotransformer is shared and connected together

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.
