FAQ

Who knows how big transformers and lines the 36V transformer uses in lighting?

No matter how many volts the output / input voltage of the transformer is, the size and the amount of the core of the transformer, the wire diameter of the winding lead and the lead thickness must be determined by the transformer capacity. Example: input 220V, output 36V load is 36v/40w light bulb 6, so the primary needs 0.72, secondary use 1.81 diameter enameled wire winding system. The transformer capacity is about 250VA.

The difference between lighting transformers and control transformers

A control transformer is a low voltage appliance, usually used as a power supply or part of a lighting for the control of electrical equipment such as machine tools. There are usually two different voltage outputs,

Why is the two side of the lighting transformer grounded?

The metal shell transformer grounding grounding protection is called: under normal circumstances is not charged, electrical metal and in the damaged insulation or other circumstances may be charged part (i.e. metal structure and insulation electrical parts part) and grounding wire connected to a reliable way to protect people.

Is the substation separate from the power and illumination transformer?

The power and lighting power supply in the substation need not be separated. In a large capacity power plant, the lighting can be electrically powered to ensure that the generator is stopped. The lighting source is often separated from the lighting transformer and powered by other power supplies.

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.

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.

Can the 500 volt lighting transformer be changed into an electric welder?

500 VA transformer should not be used as an electric welding machine, so it is very difficult to reform the system, so it is better to buy a new electric welder

What transformer can be used in a safety voltage lighting transformer?

An isolated transformer is a transformer that is electrically isolated from an input winding and an output winding. The isolated transformer is used to avoid accidental touching of the charged body at the same time, and the isolation of the transformer is to isolate the current of the former side winding coil.
