FAQ

Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?

See whether the lamp power saving, can not see whether it has a transformer, but to see the light efficiency of the lamp, that is, the ratio of light flux to power!Popular speaking, that is, spend the same electricity to see who sends more light!So, when comparing, ask what the light is, then judge again!The luminous efficiency unit is LM/W

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

How many transformers should be used in the lighting of the 36V transformer, which should be chosen according to the power required. The greater the load (power), the greater the power to select the transformer.

The transformer zero line has broken, has the result to the household illumination circuit?

The lighting circuit mostly 3 phase unbalanced load, there will be zero drift, zero if the transformer line is broken, part of the lighting circuit to form a series of equipment in the case of two-phase circuit, circuit voltage is decreased and the lighting brightness is not enough, circuit voltage increases, the lamp burned;

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.

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?

The no-load voltage is higher (about 70~90 V), the arc can be smoothly started, and the voltage will be reduced to about 30 V when welding.

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.

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.
