Q: 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?: Because some transformers are connected to 380V and 0, they can be 1000VA capacity, but because of the same line diameter, the 220V terminals and 0 can not provide the capacity of 1000VA.

Q: Why is the two side of the lighting transformer grounded?: Single-phase transformer two side lighting to the ground, on the one hand is the lighting products now contain many semiconductor devices such as diodes, transistors, integrated circuits, semiconductor devices vulnerable to electrostatic damage, two side grounding contributes to the surge pressure factors produced by residual electrostatic discharge stay in the main circuit, avoid electrostatic protection, product life. In the 21 aspect, there is distributed capacitance between the two side and the primary side of the power transformer, and the high frequency surge disturbance caused by the primary side current source will directly enter the two side to the main circuit through the distributed capacitor. These unnecessary high frequency interference may jump into the sensitive signal source, make the control system malfunction, and the two side grounding of the power transformer can eliminate most of the undesirable effects of the distributed capacitance.

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 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: 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: 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: Can the 500 volt lighting transformer be changed into an electric welder?: 500 VA transformer should not be used as an electric welding machine, so it is very difficult to reform the system, so it is better to buy a new electric welder

Q: What's the function of the lighting transformer?: Applies to some requirements for safe voltage 24V - 36V lighting sites. Such as: basement, tunnel, dangerous goods warehouse and so on. Then there is the (mobile, temporary) safety lighting for the overhaul.

Q: Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design: Pe=19.5KW, installed capacityKx=1 coefficient of demandPjs=KxPe=19.5KW, calculated loadCOS, phi, =0.85, power factorIjs=KxPe/3/220/cos phi (Ijs calculates current, voltage, 380V/220V, three-phase)=1*19.5*1000/3/220/0.85=34.76A

Q: How to calculate the rated capacity of small transformers for lighting purposes?: If the flow of large capacity motor starting current and welding machine, large current flows in a short period of time in the load even when the power equipment capacity can withstand current flow in a short time, but due to a voltage drop excitation electromagnetic switch relief, the motor can not start, damaged or the undesirable phenomenon of welding. Therefore, the voltage drop rate should be calculated as less than 10% of the supply voltage, as calculated below.
