Problems solved by technology

[0002] Traditional fuses, circuit breakers, residual current protectors, etc. are used as backup protectors for surge protectors. Because their lightning wave current capacity is smaller than that of surge protectors, surge protectors cannot fully exert their ability to discharge lightning waves. At the same time, after the surge protector is slowly aging, it will not trip when the leakage current gradually increases, which may easily cause a fire

Embodiment Construction

[0012] In order to further understand the content, features and effects of the present invention, the following examples are given, and detailed descriptions are given below with reference to the accompanying drawings.

[0013] The structure of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] A backup protector, comprising a first connection terminal 2 and a second connection terminal 9 respectively installed at both ends of a casing 1, an electromagnetic release 12 located in the upper compartment and a discharge tube 11 located in the lower compartment;

[0015] A reset metal wire 13 is connected between the touch buckle 3 and the hand brake 4, and the reset metal wire 13 can be a coil spring, which is used to push the hand brake 4 to reset the touch buckle 3 to the movable end of the electromagnetic release 12 after tripping ;

[0016] Discharge tube 11 can adopt discharge elements such as discharge tube, graph...

Abstract

The invention discloses a backup protector. A resetting metal wire is used to connect the touch buckle and the handbrake. One end of the electromagnetic trip is connected with the lead-out pin of thefirst wiring terminal and the other end is connected with the movable contact through a soft copper braid wire. One end of the static contact is contacted and connected with the extraction pin of thesecond connection terminal and the other end of the static contact is connected with the discharge tube. The touch buckle and the movable contact are respectively positioned at the two ends of the electromagnetic trip. The touch buckle is connected with the tripping switch. The tripping switch is respectively connected with the handbrake and the tripping contact and the tripping contact is connected with the movable contact. The electromagnetic release of the upper bin solves the problem that the leakage current slowly increases and is easy to cause fire or explosion. The discharge tube of thelower bin solves the problem that the fuse, the circuit breaker, the residual current protector and the like are used as the backup protector of the surge protector. The surge protector cannot give full play to the problem of the ability to drain the lightning wave due to the fact that the through-flow capacity of the lightning wave is smaller than the surge protector.

Description

technical field [0001] The invention belongs to the field of surge protection, in particular to a backup protector. Background technique [0002] Traditional fuses, circuit breakers, residual current protectors, etc. are used as backup protectors for surge protectors. Because their lightning wave current capacity is smaller than that of surge protectors, surge protectors cannot fully exert their ability to discharge lightning waves. At the same time, after the surge protector slowly ages, it will not trip when the leakage current gradually increases, which may easily cause a fire. Contents of the invention [0003] Aiming at the problems existing in the prior art, the invention provides a backup protector. [0004] The present invention is achieved in that a kind of back-up protector comprises: [0005] The first terminal and the second terminal are respectively installed at both ends of the shell, the electromagnetic tripper located in the upper compartment and the disc...
