FAQ
- The difference between lighting transformers and control transformers
- A control transformer is a low voltage appliance, usually used as a power supply or part of a lighting for the control of electrical equipment such as machine tools. There are usually two different voltage outputs,
- 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;
- Why is the two side of the lighting transformer grounded?
- Neutral grounding of three-phase transformer is called working earthing: the main function is to strengthen the stability of low-voltage system potential, and to reduce the risk of overvoltage caused by grounding, high voltage, short circuit, etc..
- Lighting, lights, transformers, bulb brightness is too low, what's the matter?
- Line light for safety light, voltage 24 volts and 36 volts, pay attention to the bulb and transformer voltage matching.
- Why should lighting transformers be used in factories and mines?
- There are two cases. One is the general factories and mines, and the low voltage is three-phase four wire system, and the neutral point is directly grounded. Between the phase line and the zero line is 220V, which can be connected with the illumination load.
- Power and lighting transformers, lighting quality will be affected much?
- Corresponding to the transformer power supply, in order to save costs and reduce costs, the choice of AC ignition method is better. Pure resistive load, the power factor is 1. The 3 *100W=300W is the capacity of the required transformer
- Why is elevator lighting transformer installed?
- 3 a power outlet shall be provided at the bottom pit.4 the cables and wires laid in the hoistway shall be flame retardant and damp resistant, and shall be protected by a nonflammable wire, conduit, or wire slot, with no use of wires, conduits, or wire slots made of combustible material.5 an elevator attached to a building whose wiring, materials and methods and electrical components used shall take into account the effects of climatic conditions and shall take waterproof measures.Lighting transformers in order to obtain 36V voltage
- How many can you bring with 220V? How many can you bring with 380V? There are 3 terminals on the transformer. There are 220V, 380V, 0, three terminals. 220V is the 220V terminal and the 0 connection. How can the 380V be connected? Is it 380V and 0 or 380V and 220V?
- Connect 220V method, FireWire 220V terminal, zero line 0 terminal, 380V terminal is not connected.Connect 380V method, A phase 380V terminal, B phase 0 terminal, 220V terminal is not connected.
