Abstract
The invention belongs to breaker technical field, and in particular to a kind of anti-jump method of breaker.The anti-jump method of the breaker, comprises the following steps：Connected again in combined floodgate monitoring circuit anti-trip relay 1KA normally closed contact, this improvement is after the completion of anti-jump, when closing circuit not yet recovers, by 1KA normally closed contact TWJ loops are temporarily disconnected, treat closing circuit return, i.e., 107 without positive electricity arrive and 1KA return when, 1KA normally closed contact closure, TWJ loops connect, so as to solve it is anti-jump after can not close a floodgate the problem of.Its advantage is：It can match with the control loop of original microcomputer protecting device; realize reliable breaker tripping and closing function; breaker open operation speed is shorter after being transformed by electric loop can make electrical equipment more rapid breaking arc, high current system when short circuit accident occurs, so as to protect the injury of the high-power electric equipment of system to be preferably minimized.
Description
Technical field
The invention belongs to breaker technical field, and in particular to a kind of anti-jump method of breaker.
Background technology
Electric fault have divide-shut brake contact adhesion or can not disconnect, anti-trip relay failure can not disconnect divide-shut brake in time,
The auxiliary contact of breaker can not be opened, energy storage limit switch is not in place etc., after relay protection automatic unit startup, may be gone out
Now close a floodgate or switching winding is smoldered because of overheat so that the electrification time of divide-shut brake coil is long and causes coil to overheat and burn
Ruin, energy storage motor burns.
The content of the invention
The present invention realizes the breaker of reliable breaker tripping and closing function to make up the defect of prior art there is provided a kind of
Anti-jump method.
The present invention is achieved through the following technical solutions：
A kind of anti-jump method of breaker, comprises the following steps：Connect an anti-trip relay 1KA again in combined floodgate monitoring circuit
Normally closed contact, this improvement is after the completion of anti-jump, when closing circuit not yet recovers, and is caused by 1KA normally closed contact
TWJ loops temporarily disconnect, treat closing circuit return, i.e., 107 without positive electricity arrive and 1KA return when, 1KA normally closed contact is closed
Close, TWJ loops connect, so as to solve it is anti-jump after can not close a floodgate the problem of.
The beneficial effects of the invention are as follows：A kind of anti-jump method of breaker of the present invention can be with original microcomputer protecting device
Control loop matches, and realizes reliable breaker tripping and closing function, and breaker open operation speed is shorter after being transformed by electric loop can
So that electrical equipment more rapid breaking arc, high current system when short circuit accident occurs, so as to protect the big work(of system
The injury of rate electrical equipment is preferably minimized.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Accompanying drawing 1 is the circuit diagram of the anti-jump loop of breaker operation mechanism of the present invention.
Embodiment
Accompanying drawing 1 is a kind of specific embodiment of the invention.A kind of anti-jump method of breaker of the invention, comprises the following steps：
Connected again in combined floodgate monitoring circuit anti-trip relay 1KA normally closed contact, this improvement is closed a floodgate after the completion of anti-jump
When loop is not yet recovered, by 1KA normally closed contact TWJ loops are temporarily disconnected, treat that closing circuit is returned, i.e., 107
Without positive electricity arrive and 1KA return when, 1KA normally closed contact closure, TWJ loops connect, so as to solve it is anti-jump after can not close
The problem of lock.
The present invention is not limited to the above-described embodiments, anyone should learn the present invention enlightenment under make with the present invention
With same or like technical scheme, each fall within protection scope of the present invention.
The technology of the invention not being described in detail, shape, construction part are known technology.
Claims (1)
1. a kind of anti-jump method of breaker, it is characterised in that comprise the following steps：Connect one and prevent again in combined floodgate monitoring circuit
Relay 1KA normally closed contact is jumped, this improvement is after the completion of anti-jump, when closing circuit not yet recovers, and passes through the normal of 1KA
Contact is closed so that TWJ loops temporarily disconnect, treats that closing circuit is returned, i.e., 107 arrive without positive electricity and during 1KA returns, 1KA's
Normally closed contact close, TWJ loops connect, so as to solve it is anti-jump after can not close a floodgate the problem of.
