Q:Power and lighting transformers, lighting quality will be affected much?

The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, the cold resistance of the filament and the starting factor at the same time, it is better to choose the 400VA transformer.

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

If the transformer is not calculated, the loss is the same. If the calculation is the latter, save electricity.

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

We have produced many low voltage lighting transformers, such as outdoor waterproof, high-power stage lighting, as well as indoor small power transformers, customer response, but also good! For example, Guangzhou Color Art Lighting Co., Ltd., before them, our reputation is good!

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

Pure resistive load, the power factor is 1.3 *100W=300W, is required for the capacity of the transformer.

Q:Why should lighting transformers be used in factories and mines?

But in many cases, such as mines and machinery, the voltage is too high and unsafe. The lighting transformer is then used to reduce the voltage to the so-called "safety voltage""

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: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.

Q:Why is elevator lighting transformer installed?

1) a lamp shall be installed at the highest and lowest point 0.5m away from the hoistway, and a light shall be installed at intervals not exceeding 7m, and a control switch shall be installed in the engine room and the bottom pit respectively;2) the lighting power supply for car top and hoistway shall be 36V; when 220V is adopted, the residual current action protector shall be installed;3) there is no lighting device for a closed well road with sufficient lighting conditions around the hoistway.

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

General line lights are 36 volts, especially in the damp and harsh environment, the light transformer adopts 24 volts voltage;After the use of light transformers, can generally live operations, first, low voltage, less dangerous, and the two is a transformer isolation, safety is greater, so you can live work, generally there will be no electric shock accident. (as long as the power is not in the hands and hands, the two end of the power supply, there will be no electric shock.)

Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?

The number of tables in this table is increasing when the table rings to show 1.Method 2 is only to measure the capacitance is good or bad, can not be measured capacity.
