Distribution box manufacturer: What is the clearance of electrical equipment in distribution box?

Distribution box manufacturer: What is the clearance of electrical equipment in distribution box? Because the cable sheath raw material (composite resin) around the metal conductor is electrically conductive, it may cause the cable sheath raw material to exhibit induced electrification, in other words, breakdown voltage.

Distribution box manufacturers: explosion-proof distribution box actual operation should pay attention to what key points?

The distribution box manufacturer said that after the explosion-proof distribution box is connected to the switching power supply, many people will check whether the route of the explosion-proof distribution box is plugged in. At this time, even if the explosion-proof distribution box has factory inspection, do not directly use hand touch or body contact, but it is safe not to remove all places. In addition, when the explosion-proof distribution box is in operation, it is impossible to disassemble and assemble. First, disconnect the switching power supply, and then use the test pen to detect that there is no switching power supply, in order to carry out disassembly, assembly and operation and maintenance work.

Distribution box manufacturers: stainless steel distribution box should be how to achieve the ideal state?

Distribution box manufacturers said that in recent years, with the rapid development of science and technology at the level of substation equipment, the demand for substation equipment is getting higher and higher. The distribution box manufactured by the distribution box manufacturer is an indispensable part of the substation equipment, and it is also very important to update and transform it. In order to adapt and facilitate the knowledge of electricity safety, the distribution box looks very important. All aspects of the distribution box must be improved. The improvement of the distribution box starts from the following aspects:

Dry-type transformer manufacturers: dry-type transformer selection techniques

Dry-type transformer manufacturers said that the safe operation and service life of dry-type transformers largely depend on the safety and reliability of the insulation of the transformer package components. The heat and cold of the package components exceed the heat and cold of the insulation and damage the insulation, which is one of the main reasons for the normal operation of the transformer. Therefore, it is very important to monitor and alarm the working cold and hot of the transformer.

Dry-type transformer manufacturer: working principle of dry-type isolation transformer

Dry-type transformer manufacturers, dry-type isolation transformers are widely used in AC 50Hz to 60Hz, voltage below 660V circuit. The various input and output voltages of the product, the connection group, the number and position of the adjustment tap (usually ± 5%), the distribution of winding capacity, the configuration of the secondary single-phase winding, the use of the rectifier circuit, and whether the housing is required, can be carefully designed and manufactured according to user requirements.

Dry type transformer manufacturers: dry type transformer how to check?

Dry-type transformer manufacturers said that the input and output three-phase power lines are connected to phase A, phase B and phase C respectively according to the bus color of the transformer wiring board, green and red. The neutral line is connected to the neutral zero line of the transformer voltage, and the grounding line, the transformer shell and the transformer center point are connected. Usually, the grounding line and the neutral line are led out from the neutral point of the transformer. (If the transformer has a cabinet, it should be connected with the grounding mark of the cabinet). Check the input and output lines to make sure they are correct.

Temperature Control System of Dry-Type Transformer

The safe operation and service life of dry-type transformers largely depend on the safety and reliability of transformer winding insulation. The insulation damage caused by the winding temperature exceeding the insulation withstand temperature is one of the main reasons why the transformer cannot work normally, so it is very important to monitor the operating temperature of the transformer and control its alarm.
