Q: 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.

Q: 1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires: To 30VA/ square meters, the transformer needs 30KVA, with two 120 square copper wire. Specific should be used to determine the total power of the lighting transformer.

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: 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.

Q: The transformer zero line has broken, has the result to the household illumination circuit?: When the zero line break line is not broken, the voltage drift of the point voltage leads to the rise of the 220V branch voltage and the reduction of the 220V branch voltage

Q: Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40: I don't know how much the output voltage of your transformer is, but the internationally accepted voltage below 36V is the voltage that is not harmful to the human body

Q: 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.

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: What's the function of the lighting transformer?: In addition, can be rated power supply voltage of not more than 1000V AC circuit, as a machine tool and mechanical equipment control power, work lighting and signal light power supply, can also be used as a small power supply!

Q: Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design: Because of the brightness of the 36V safety voltage lamp brightness in the overhaul work is not enough, so now the well lighting design should not be 36V, and replaced by 220V, and only need to add a leakage protector on it.
