- Q: How many power illuminator can 5Kva 36V transformer drive?
- Of course, if you want to bring more is not impossible, but depends on the working conditions, the actual power = nominal power, short time use (to ensure that the transformer temperature rise is not too high) is also available
- Q: What transformer can be used in a safety voltage lighting transformer?
- 220V/36V or 24V isolation transformer. Double winding, high and low voltage coils, not connected.
- Q: Why is the two side of the lighting transformer grounded?
- The metal shell transformer grounding grounding protection is called: under normal circumstances is not charged, electrical metal and in the damaged insulation or other circumstances may be charged part (i.e. metal structure and insulation electrical parts part) and grounding wire connected to a reliable way to protect people.
- 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: Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
- What you think? Your light is 220V, right. Over 36V, it's better not to live with electricity unless there is good protection
- 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: Does the lighting work properly? Doesn't that power equipment start voltage unstable?
- As long as the capacity of the transformer is enough, the voltage fluctuation of the line will be sure to occur when the high power equipment is started. Such fluctuations do not have much impact on the lighting.
- Q: Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.
- The self winding transformer is connected by all its windings, and depends on the position of the sliding contacts to change the magnitude of the voltage. Therefore, there is not only a magnetic connection between the primary winding of the autotransformer (the power circuit) and the two winding (the power supply circuit), but also the direct connection of the circuit. It forms a circuit with the earth, so it can not be used as the power source of the safety voltage
- Q: 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
- 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
