Abstract

The invention provides a surge backup protector which comprises a shell; a circuit module; an electromagnetic tripper which is provided with a jacking rod; a jacking rod reset member which is pivotally arranged on the shell and cooperated with the position of the jacking rod; an operating mechanism which comprises a base frame which is pivotally mounted on the shell in a resettable way; and a conductive system which comprises a wiring assembly, a main lead, a moving contact rod assembly and a static contact rod assembly which can be contacted and cooperated with the moving contact rod assembly. An iron core assembly is arranged at the outer periphery of the main lead. The iron core assembly is communicatively connected with the input end of the circuit module through a mutual inductance assembly. The moving contact rod assembly is drivingly cooperated with a transmission rod. According to the surge backup protector, the functions of no gap, zero arc and instantaneous high-frequency high current of the conductive system can be realized and the technical requirements of cutting off power frequency current can also be met, and the surge backup protector has low residual voltage and long service life.

Description

technical field [0001] The invention relates to the field of surge protection equipment, in particular to a surge backup protector. Background technique [0002] Lightning disasters are one of the most serious natural disasters, causing countless casualties and property losses all over the world every year. With the extensive application of electronic and microelectronic integrated equipment, lightning overvoltage and lightning electromagnetic pulse cause more and more damage to systems and equipment. The use of surge protectors to suppress surges and instantaneous overvoltages on the lines, and to discharge overcurrents on the lines has become one of the important links in modern lightning protection technology. [0003] Surge backup protectors (that is, backup protectors for surge protectors) are suitable for places where surge protectors (SPD) and other lightning protection equipment have been installed (such as industrial and civil buildings, electrical power stations, ...
