Q: 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.

Q: 1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires: First of all, make sure your power is too large, but you are not recommended to do so, the cost is too high, the pressure drop is too large, you can raise the voltage to 220V or higher, and then transfer to avoid power losses. If the direct transmission, the power is slightly larger, the line will be very rough, the cost will be very high

Q: Why is the two side of the lighting transformer grounded?: In the three-phase transformer, the neutral point of the three-phase transformer and the metal case are always reliably connected, and the utility model has the advantages of reliable grounding, both working grounding, protection and earthing, and protection of personal safety and equipment safety.

Q: Why is elevator lighting transformer installed?: 9.4.5 well distribution shall comply with the following requirements:1 the elevator hoistway shall be dedicated to the elevator, and no equipment, cables and other devices related to the lift shall be installed in the hoistway.2 the well shall be provided with illumination, and the illumination shall not be less than 501x, and shall comply with the following requirements:

Q: The transformer zero line has broken, has the result to the household illumination circuit?: The zero line is connected to the transformer neutral point of transformer, three FireWire for its voltage is 220 volts, according to regulations, the total can not take the zero line fuse, switch, because once the zero line is disconnected, the rest of the line will no longer be a neutral line, into the use of electrical appliances connected to two the conductor, according to the characteristics of series circuit, each phase with electrical voltage, on load distribution, change the original load smaller which phase by using electrical appliances, will damage due to excessive voltage.

Q: 3 24V100W lights, I need to use a large capacity transformer (220V change 24V)?: First look at this lamp,.24V100W, this specification is common in the headlights of large trucks, filled with inert gas, known as the small sunThe power supply comes from the generator or battery, and the mode of operation is to ignite by alternating current and direct current. In comparison with the power supply of the transformer, the method of alternating current ignition is better to save the cost and reduce the cost

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: 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.

Q: Why can't autotransformer be used as transformer for safety lighting?: The main and auxiliary coils of the autotransformer have common parts. Once the short-circuit is made, the lighting circuit is directly connected with the high voltage circuit, which is very dangerous

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.
