1. Explosion-proof plugs and explosion-proof sockets are special control equipment used in various high-risk places. They are used in places where dangerous gases are present to control electrical circuits. The outer shell is made of aluminum alloy, and the electrical components inside are all The mining place is explosion-proof, and all electrical components that can generate electric sparks are sealed to isolate it from the dangerous gas outside.

2. Whether the lightning protection socket is useful can also be seen from the working principle of the lightning protection socket. The working principle of the lightning protection socket is to use a transient voltage absorber such as a lightning arrester or a varistor to be installed between the input lines. During the time, an infinite impedance is formed. When the instantaneous voltage occurs, the impedance is rapidly reduced, and the transient energy is transferred, so as to achieve the effect of protecting the internal electrical equipment. Therefore, the lightning protection socket can effectively absorb the surge pulse from the power system, so that the electrical appliance can be used safely in harsh environments and areas with heavy lightning.
