FAQ

What type of low voltage transformer should be adopted for safety lighting power supply?

Isolated transformer, once 380V or 220V, two voltage, 36V, 24V, 12V, several categories, do not allow the use of autotransformer.

3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?

The bulb is used in the two luminescence tube combined type lamp holder, the calculation process is very complex. Different combinations, the secondary voltage is different. Because it is a DC ignition, but also consider the efficiency of rectification, but the total power is constant.

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

Depending on your load capacity, primary voltage, site reservation, etc.. For example, 3.6KW lighting, with 4KVA transformers, the primary side 380V with 2.5 square (copper wire) enough, two times the side of 25 square.

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.

How many A leakage protection switches are used in 5000VA lighting transformers?

It is widely used in the electronic industry or industrial and mining enterprises, in the machine tool and the mechanical equipment, the control power of the general electric circuit, the use of the power supply of the safety lighting indicator lamp.

Why is the two side of the lighting transformer grounded?

Single-phase transformer two side lighting to the ground, on the one hand is the lighting products now contain many semiconductor devices such as diodes, transistors, integrated circuits, semiconductor devices vulnerable to electrostatic damage, two side grounding contributes to the surge pressure factors produced by residual electrostatic discharge stay in the main circuit, avoid electrostatic protection, product life. In the 21 aspect, there is distributed capacitance between the two side and the primary side of the power transformer, and the high frequency surge disturbance caused by the primary side current source will directly enter the two side to the main circuit through the distributed capacitor. These unnecessary high frequency interference may jump into the sensitive signal source, make the control system malfunction, and the two side grounding of the power transformer can eliminate most of the undesirable effects of the distributed capacitance.

Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40

Line lights, lighting transformers in general how many low voltage, can live operation, but to do safety measures. For example, do not short-circuit, damp environment, wear insulation shoes, wearing insulating gloves and so on.In fact, all the voltage levels, as long as safety measures can be done live operation.

Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design

The previous elevator hoistway lighting required the 36V safety voltage, and you can see how many power lamps are required for the hoistway, and select the transformer
