- Q:How many A leakage protection switches are used in 5000VA lighting transformers?
- AC circuit transformer for lighting lamp is suitable for 50-60Hz, is the power supply with safety shell low-voltage safety lights, can choose 220V or 380V power supply input voltage: 0V, 220V, 380V, 0V, 6.3V, output voltage: 12V, 24V, 36V.
- Q:Which is more energy saving by using 24V500W transformer lighting and 220V500W lighting?
- See whether the lamp power saving, can not see whether it has a transformer, but to see the light efficiency of the lamp, that is, the ratio of light flux to power!Popular speaking, that is, spend the same electricity to see who sends more light!So, when comparing, ask what the light is, then judge again!The luminous efficiency unit is LM/W
- 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:The transformer zero line has broken, has the result to the household illumination circuit?
- The zero line is connected to the transformer neutral point of transformer, three FireWire for its voltage is 220 volts, according to regulations, the total can not take the zero line fuse, switch, because once the zero line is disconnected, the rest of the line will no longer be a neutral line, into the use of electrical appliances connected to two the conductor, according to the characteristics of series circuit, each phase with electrical voltage, on load distribution, change the original load smaller which phase by using electrical appliances, will damage due to excessive voltage.
- 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:How many 40W bulbs can be brought into the 1000VA lighting transformer?
- The key is that the 220V terminals and 0 can not provide 1000VA capacity?
- Q:Line lights, lighting transformers in use!! Can live line work?!! Be afraid of electric shock 40
- Line lights, lighting transformers in general how many low voltage, can live operation, but to do safety measures. For example, do not short-circuit, damp environment, wear insulation shoes, wearing insulating gloves and so on.In fact, all the voltage levels, as long as safety measures can be done live operation.
- Q:Why can't autotransformer be used as transformer for safety lighting?
- The transformer of the lighting circuit is a step-down transformer (general input 10kv., 220V). The first coil of the autotransformer is shared and connected together
- 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:Please tell me how to calculate the transformer in the lighting circuit of elevator shaft in building electrical design
- The previous elevator hoistway lighting required the 36V safety voltage, and you can see how many power lamps are required for the hoistway, and select the transformer
