- 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: Who knows how big transformers and lines the 36V transformer uses in lighting?
- Depending on your load capacity, primary voltage, site reservation, etc.. For example, 3.6KW lighting, with 4KVA transformers, the primary side 380V with 2.5 square (copper wire) enough, two times the side of 25 square.
- Q: What type of low voltage transformer should be adopted for safety lighting power supply?
- Isolated transformer, once 380V or 220V, two voltage, 36V, 24V, 12V, several categories, do not allow the use of autotransformer.
- Q: Why should lighting transformers be used in factories and mines?
- In some factories and mines (such as power plants), in order to supply power reliability, the power system is grounded in a three-phase, ungrounded, or neutral manner. In this way, the transformer must be connected to a neutral grounding type with a special transformer to supply power to the lighting.
- 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: 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 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: 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?
- Illumination transformer: usually refers to the secondary output voltage for the safety voltage 24V - 36V, only for special lighting power supply using voltage converter.
- 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
