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?
Today's lighting products, regardless of the control system or the electronic power system itself, contain many semiconductorsComponents such as rectifier diodes, transistors, integrated circuits, LED, and so on. Semiconductor components are susceptible to staticElectrical damage, the two side of the power transformer grounding, help to produce a variety of factors, high pressure, residual static electricityDrain to avoid static electricity on the main circuit, to ensure product life.
Q: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
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: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.
Q:Who knows how big transformers and lines the 36V transformer uses in lighting?
The sectional area of the wire can be calculated according to the electric power formula. The current required by the wire is calculated, and then the reference to the national standard "500 volt copper core insulated wire, long term continuous load allowable ampacity meter" is selected.
Q:Is the substation separate from the power and illumination transformer?
There is only bus in the substation, and the station is connected with the transformer from the bus. If there is no electricity even in the bus, then the substation should not be considered active.
Q: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,
Q:Why can't autotransformer be used as transformer for safety lighting?
When a fault occurs, leakage of electric leakage occurs, and the original coil is transmitted to the residents at high voltage, causing disastrous effects on the human body and property!
Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
If there is no painting can be used with a diode symbol file (measuring probe connected to the capacitor to hear a sound if the table does not ring at the table and then the general display is 1, then the pen on the emergence of the phenomenon that the capacitance is still good. If one table has been ringing that received the capacitor capacitor breakdown is broken)
