Q: Who knows how big transformers and lines the 36V transformer uses in lighting?: No matter how many volts the output / input voltage of the transformer is, the size and the amount of the core of the transformer, the wire diameter of the winding lead and the lead thickness must be determined by the transformer capacity. Example: input 220V, output 36V load is 36v/40w light bulb 6, so the primary needs 0.72, secondary use 1.81 diameter enameled wire winding system. The transformer capacity is about 250VA.

Q: What type of low voltage transformer should be adopted for safety lighting power supply?: In general, indoor transformers are used in general practice

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: 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: 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: Can the 500 volt lighting transformer be changed into an electric welder?: The no-load voltage is higher (about 70~90 V), the arc can be smoothly started, and the voltage will be reduced to about 30 V when welding.

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: 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

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.
