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: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 lighting power supply in the substation need not be separated. In a large capacity power plant, the lighting can be electrically powered to ensure that the generator is stopped. The lighting source is often separated from the lighting transformer and powered by other power supplies.

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:Who knows how big transformers and lines the 36V transformer uses in lighting?

The sectional area of the wire can be calculated according to the electric power formula. The current required by the wire is calculated, and then the reference to the national standard "500 volt copper core insulated wire, long term continuous load allowable ampacity meter" is selected.

Q:1000 square meters low voltage.36 volts lighting power supply with multiple transformers and wires

You must know the quantity and power of the lamp to determine the transformer

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: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:How to use digital multimeter to detect the quality of 36 volt low voltage lighting transformer?

The number of tables in this table is increasing when the table rings to show 1.Method 2 is only to measure the capacitance is good or bad, can not be measured capacity.

Q:Why the 21 lighting transformer must double winding type safety isolating transformers, prohibited the use of autotransformer.

The self winding transformer is connected by all its windings, and depends on the position of the sliding contacts to change the magnitude of the voltage. Therefore, there is not only a magnetic connection between the primary winding of the autotransformer (the power circuit) and the two winding (the power supply circuit), but also the direct connection of the circuit. It forms a circuit with the earth, so it can not be used as the power source of the safety voltage
