A voltage series of a specific power supply used to prevent electric shock accidents. The upper limit of this
series isIn any case, the current between two conductors or between any conductor and the ground shall not exceed the effective value of 50V AC (50-500Hz). When the grid leakage current exceeds the set value, the function that can automatically cut off the circuit or send a signal. The phenomenon, state and nature of dangerous damage caused by electrostatic discharge or electrostatic force. Relatively large hazards and damages caused by electrostatic discharge. Such as fire, explosion, human static electric shock and secondary accidents, etc. Any protection device that does not flow according to the specified flow, with short circuit, overload, phase failure, leakage and other functions. When the cable or electrical equipment fails, it can cut off the power supply before the electric spark (or high temperature) ignites the explosive mixture. When the explosive gas mixture specified inside the shell explodes, it will not ignite the explosive gas mixture around the shell. Under the action of the explosion pressure of the explosive gas mixture in the shell, the shell has sufficient mechanical strength so as not to cause deformation or damage that may impair the explosion isolation performance.
