No fault breaking phenomenon is mainly due to adverse weather conditions such as storms caused

Traditional drop-out fuse of trouble breaking phenomenon is mainly due to adverse weather conditions such as storms Electric energy meter When the contacts are mounted on a fully enclosed stainless steel cover after fouling avoid electric meter sand and snow, resistance to natural disasters, the performance is very strong, thus eliminating the trouble-breaking electric transformer the safe operation of the line to provide a reliable guarantee . While increasing the contact surface of the conductor, and the silver-plated contact surfaces significantly reduce the contact resistance, the contact heating and flaming phenomenon due to oxidation corrosion can be avoided, the interpolation type structure, but also to solve the pull switch operation caused by the arc short-circuit problem.
