Safety Protection Power Supply Manufacturers

how to carry on the electricity safety protection

Every year there are some accidents caused by inadvertent electrocution, as a charger factory, in addition to try to produce safe and reliable power products, here also want to share some knowledge of electricity safety protection.

There are mainly the following protection methods:

1. Protective grounding :In the power neutral point is not grounded in the power distribution system used (three-phase three-wire system). The shell of the power equipment and the earth with the grounding body or wire reliable grounding, once the insulation of the equipment is damaged, the equipment shell charged, due to reliable contact with the ground, its potential is basically zero, the human body touches the equipment shell, the current flowing through the human body is very small, will not be dangerous.

2. work grounding: in the power neutral grounding power distribution system, mostly used in low-voltage systems. Neutral grounding of the transmission system, the role of protective grounding is not perfect, leakage, people still have the risk of electric shock. The most perfect method is to connect the shell of electrical equipment with the neutral wire. Once there is an accident in one phase, and the electrical equipment shell is connected, the instantaneous current between the phase line and the neutral line will fuse, playing a protective role to ensure personal safety. In the same power distribution system, do not allow a part of the equipment using protective grounding and another part of the equipment using the work grounding.

3. Frequent comprehensive safety inspection of electrical equipment: check for leakage, check the degree of insulation aging, check for bare leakage parts, check for irregularities in the installation of equipment.

Eahunt charger factory tell you, through these methods, you can do a good job of electricity safety protection, to ensure the safety of electricity.
