Q:Why can't autotransformer be used as transformer for safety lighting?
The main and auxiliary coils of the autotransformer have common parts. Once the short-circuit is made, the lighting circuit is directly connected with the high voltage circuit, which is very dangerous
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: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:How to calculate the rated capacity of small transformers for lighting purposes?
If the flow of large capacity motor starting current and welding machine, large current flows in a short period of time in the load even when the power equipment capacity can withstand current flow in a short time, but due to a voltage drop excitation electromagnetic switch relief, the motor can not start, damaged or the undesirable phenomenon of welding. Therefore, the voltage drop rate should be calculated as less than 10% of the supply voltage, as calculated below.
Q:Does the lighting work properly? Doesn't that power equipment start voltage unstable?
The transformer that power supply company manages, it is to supply motive power and illumination generally, namely the lighting transformer that does not have special illumination to illuminate. Units of their own transformers, is generally the case. The utility model has the advantages that the transformer and other equipment can be fully utilized, the efficiency is high, and the external power supply circuit does not need to be divided into power transmission lines and lighting circuits, and is simple and orderly, and the cost is low. As for the price of electricity, it is usually negotiated a power and lighting each percentage of the electricity to calculate and receive.
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: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 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:What's the function of the lighting transformer?
In addition, can be rated power supply voltage of not more than 1000V AC circuit, as a machine tool and mechanical equipment control power, work lighting and signal light power supply, can also be used as a small power supply!
Q:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?
General digital multimeter has a capacitor (some of the files with a million capacitance test table of Jack, some use pen)
