Abstract
The present invention relates to a kind of asynchronous immediate processing methods of split-phase circuit-breaker switching on-off, its processing step is: utilizing the spare contact of the auxiliary switch of GIS device three-phase breaker, multi-parallel 1 is distinguished on three-phase separate, closing circuit respectively to spare normally-closed contact, in addition totally 2 pairs of original 1 pair of contact, after carefully connecting the wire test close a floodgate, separating brake not same period, breaker can successfully solve the problems, such as three-phase switching on and off not same period, it only needs 1-2 hour that can handle three-phase switching on and off not same period problem well, greatly shortens fault handling time.After carefully connecting the wire test close a floodgate, separating brake not same period, breaker can successfully solve the problems, such as three-phase switching on and off not same period.
Description
Technical field
The invention belongs to power supply and distribution technical fields, are related to a kind of asynchronous quick processing side of split-phase circuit-breaker switching on-off
Method.
Background technique
Currently, power supply system largely uses domestic GIS device, and after GIS device uses 3-5, generally existing switch
The defect of auxiliary contact poor contact, the auxiliary contact that access control loop uses be easy to cause oxygen because of multipass direct current
Change, contact resistance is excessive, and the time for causing switching on and off to be connected, there are asynchronous.Causing switching on and off coil to obtain the electric time just has fastly
Slowly, lead to GIS device breaker switching on and off three-phase not same period, even cause breaker can not switching on and off when serious.And it does not connect
Entering the spare auxiliary contact that control loop uses, then there is no such cases because not passing through direct current.The three-phase of breaker is different
Phase can service life, performance and power grid security on breaker, stability there is certain influence.Since breaker has tens pairs of auxiliary touchings
Point, replacement switch auxiliary contact element manipulation amount is big, and replacement is complicated, overlong time, when discovery GIS device breaker exists point,
Close a floodgate not the same period when, replacement the auxiliary switch time it is long, need 6-10 hour, route made not restore electricity as required in time.
Summary of the invention
In order to overcome the disadvantages mentioned above of the prior art, it is asynchronous quickly that the present invention provides a kind of split-phase circuit-breaker switching on-off
Processing method is divided on three-phase separate, closing circuit respectively using the spare contact of the auxiliary switch of GIS device three-phase breaker
Other multi-parallel 1 to spare normally-closed contact (with totally 2 pairs of original 1 pair of contact), after carefully connecting the wire test close a floodgate, separating brake not same period, break
Road device can successfully solve the problems, such as three-phase switching on and off not same period.
The technical solution adopted by the present invention to solve the technical problems is: a kind of split-phase circuit-breaker switching on-off is asynchronous fast
Fast processing method, processing step are:
Using the spare contact of the auxiliary switch of GIS device three-phase breaker, distinguish on three-phase separate, closing circuit respectively mostly simultaneously
Join 1 pair of spare normally-closed contact, in addition totally 2 pairs of original 1 pair of contact, test is closed a floodgate after carefully connecting the wire, the same period, breaker be not equal for separating brake
It can successfully solve the problems, such as three-phase switching on and off not same period, it is only necessary to which 1-2 hour can handle three-phase switching on and off not same period well
Problem greatly shortens fault handling time.
The beneficial effects of the present invention are: quickly solving GIS device auxiliary contact defect causes to switch switching on and off not same period
The problem of；Replacement mechanism (falling on condition that GIS device operating mechanism is intact) is not needed；Replacement auxiliary switch is not needed yet
(on condition that at least there are also 1 pair of normally-closed contacts, the spare contact of 2 pairs of normally opened contacts on every phase auxiliary switch for circuit breaker), it is only necessary to
1 pair of normally-closed contact, 2 pairs of normally opened contacts in parallel, can quickly handle the asynchronous failure of three-phase well；Reduce maintenance breaker
Difficulty shortens maintenance time, while also significantly reducing maintenance cost；It can be generalized to just respectively and mostly a pair of when device fabrication
A possibility that auxiliary contact play the role of shunting, reduce contact oxidation.
Detailed description of the invention
Fig. 1 is auxiliary switch wiring diagram before being transformed；
Fig. 2 is auxiliary switch wiring diagram after transformation.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
Referring to Fig. 1, a kind of asynchronous immediate processing method of split-phase circuit-breaker switching on-off is implemented preceding switch auxiliary contact and is connect
Line situation: the auxiliary of GIS device breaker threephase switch help contact be the series connection of two normally-closed contacts (as shown in figure 1 1.-
3.) or two normally opened contacts series connection (as shown in figure 1 4. -9.), if because there is oxidation contact in one of contact
When bad, will cause control loop cannot form access, and can not close a floodgate switch either separating brake.
Referring to fig. 2, auxiliary contact wiring condition is switched after implementation: in the auxiliary contact of GIS device breaker threephase switch
Respectively on three-phase sub-gate circuit multi-parallel 1 to normally-closed contact (in such as Fig. 2 1. -3. with original 1 pair of normally-closed contact composition 2
1. ' -3. ' to normally-closed contact), respectively on three-phase closing circuit multi-parallel 1 to normally opened contact (in such as Fig. 2 4. -9. with original
By 1 pair of normally opened contact form 2 pairs of normally opened contacts 4. ' -9. '), to improve the reliability of switching on and off circuit conducting, in this way may be used
To guarantee that sub-gate circuit, closing circuit reach the three-phase same period.
