Distribution box manufacturers: what is the electrical gap and breakdown voltage

1. Breakdown voltage is based on the diameter of common faults in the middle of two electronic devices measured along the surface of the cable sheath or in the middle of the web page for safety prevention of electronic components and mechanical equipment (the current value is not in the two aspects of high-power electrical appliances and switching power supply circuits). That is to say, under different circumstances, because the cable sheath raw material (composite resin) around the metal conductor is electrically conductive, the cable sheath raw material may be induced to be electrified, in other words, the breakdown voltage.

2. Electrical equipment gap is the indoor space design interval that can be measured in the middle of two electronic devices or between electronic devices and mechanical equipment safety prevention web pages. In other words, under the premise of ensuring the stability of electrical equipment characteristics and safety factor, the cable sheath route is guaranteed according to the vapor.

Distribution box manufacturers: indicators of bare transmission lines

The gap between the bare transmission line in the middle of the low-voltage metal material meter box and the electrical equipment in the middle of the shell is much larger than 20mm, and the gap between the bare transmission line in the control circuit and the metal product of the grounding system is much larger than 20mm. When the distance between the enclosed buses is less than 20mm, the method of binding the cable sheath shall be used, and the distance shall be as far as possible according to the following regulations:

Distribution box manufacturers: the role of electrical equipment gap and breakdown voltage

Simply speaking, the gap and breakdown voltage of electrical equipment inside the low-voltage distribution box are actually two basic parameters related to the electrical insulation layer. In the application of industrial control products such as relays and power switches, in accordance with relevant standards, appropriate electrical equipment intervals and breakdown voltages should be set to maintain the stability of their electrical characteristics.

distribution box manufacturers: distribution box clean

The distribution box is closely related to our lives, the daily maintenance of the distribution box is to be done, then how should the distribution box be cleaned.

Before cleaning the distribution box, the switching power supply must be cut off before it is cleared. If it is cleaned under the condition of plug-in, it is very easy to cause problems such as short-circuit faults. Therefore, it is necessary to check whether the power supply circuit has been cut off before clearing.

Attention should be paid not to attach water to the distribution box. Once water is found, it is usually wiped with a dry towel. Water is conductive, needless to say, everyone knows this. Therefore, the distribution box must be placed in a dry and manic environment before it can be plugged in. In addition, it must not be possible to use irritating chemicals to clean the distribution box, and the distribution box should be prevented from touching irritating solutions or gases. If the distribution box encounters irritating solution or gas, it is easy to cause its surface to be rusted and rusted, which endangers its beauty and is not beneficial to the daily maintenance of the distribution box. Therefore, a good method is to apply a special cleaning liquid for electrical equipment.
