The voltage for electrical strength and power frequency sinusoidal is 2000V without breakdown and flash over when lasts 1minute
It can last 1 minute at the rated current of two times
Wave form Distortion
No additional waveform distortion
it offers the protections against over voltage,over current,phase shortage and phase-sequence(The single-phase offers no protection against the phase shortage and phase-sequence)and mechanical failure
≤1s(in the condition that the external voltage changes is 10%)
- 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 elevator lighting transformer installed?
- Is that the kind of 220V change 36V ah, if it is that kind of thing, I think it should be for security reasons. After all, 36V is a safe voltage. The damage to humans is slightly smaller than that of 220V.
- Q:Can the 500 volt lighting transformer be changed into an electric welder?
- The structure of the electric welding machine is different from that of the transformer, and the magnetic gap of the iron core can be adjusted so that the welding current can be changed. In addition, the output voltage of the welder is also soft
- Q:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires
- To 30VA/ square meters, the transformer needs 30KVA, with two 120 square copper wire. Specific should be used to determine the total power of the lighting transformer.
- Q:Is the substation separate from the power and illumination transformer?
- The power and illumination of the substation are all used on a transformer, which is separated by power and lighting by the station screen of this transformer.
- Q:How is the lighting power of the 380V transformer calculated?
- With a light bulb with 4KVA load, the premise of the distance can be Mrs. face light bulb, dark can light the best load, 3KVA bulb brightness
- Q:How to calculate the rated capacity of small transformers for lighting purposes?
- In view of the power [kVA] conversion of each load, multiplied by the amount of consumption, according to the importance of the load, equipment location, voltage statistics, set the load line and load place of plastic case transformer capacity and its connection position. The future load power equipment shall be judged on the basis of prior installation or consideration of the economy in terms of equipment addition, installation, etc..
- Q:Power and lighting transformers, lighting quality will be affected much?
- The quality of transformer itself, coupling coefficient, overload capacity, as well as the impact current of the bulb, the cold resistance of the filament and the starting factor at the same time, it is better to choose the 400VA transformer.
- Q:Lighting, lights, transformers, bulb brightness is too low, what's the matter?
- If you share a power line, you must calculate the current and select the appropriate wire to ensure normal pressure drop and safe use.
- 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.
