Description
Technical field
The utility model belongs to the switch cubicle field, and particularly a kind of circuit breaker with novel five anti-linkage structures is specially the circuit breaker of 35KV metal armouring high-tension switch cabinet.
Background technology
But polygamy has the 35KV high voltage switchgear of circuit breaker cart withdraw-type in the power supply-distribution system, and its equipment has five anti-chain requirements.Comprise in the five anti-chain requirements: the switch cubicle inner breaker can not enter into the service position after test position is closed a floodgate; When the switch cubicle inner breaker closes a floodgate operation in the service position, can't be with the circuit breaker position of deactivating.
At present; Realize that above-mentioned chain method adopts mostly: at circuit breaker set inside interlocking gear; Under the situation that circuit breaker closes a floodgate in test position or service position, circuit breaker is led in/out operation when producing initial less displacement, interlocking gear drives close/open machine and makes breaker open operation; Just in the process that circuit breaker is advanced by force with breaker open operation, and then realize chain requirement.
This structure possibly occur under the situation of Circuits System charging operation, and moving contact on the circuit breaker and the fixed contact on the switch cubicle produce relative motion, and it is stable to influence Circuits System.And, because of processing and rigging error can cause making the initial displacement size control of breaker open operation not accurate enough, dynamic/static contact disengaging in advance under the separating brake situation possibly appear not having, chain fail safe is exerted an influence.
The utility model content
The purpose of the utility model provides a kind of circuit breaker with novel five anti-linkage structures, can solve the above problems.
The technical scheme that adopts is:
A kind of circuit breaker with novel five anti-linkage structures; The three-phase contact arm, the pole that comprise mutual corresponding assembling; The protective plate, major loop framework, the spring that also comprise mutual corresponding assembling divide and lock operating mechanism, preceding guidance panel, chassis and grounding contact; This is known technology, so repeated description not.
Its technical essential is:
Spring divides and lock operating mechanism bottom mechanism for mounting push rod.
Installing moving block stent support divide-shut brake control moving block on the chassis; Divide-shut brake control moving block is connected with rotation axis with third connecting rod through interconnective first connecting rod, second connecting rod; Turning block is fixed on the rotation axis, and the turning block position is corresponding with the handle hole interstage sleeve.Rotation axis is installed on the chassis through axle bed.
Setting operation hole, handle hole position interstage sleeve.
Spring divides and lock operating mechanism bottom mechanism for mounting push rod, is known technology, so repeated description not.
Through in circuit breaker, be provided be linked mutually lead in/out handle hole interstage sleeve and divide-shut brake control structure; Make circuit breaker cart when closing a floodgate, can not be inserted into and lead in/out in the handle hole, and then can not lead in/out operation circuit breaker cart with leading in/out handle; Divide-shut brake controlling organization limiting circuit breaker can not close a floodgate in the operating process when circuit breaker cart is leading in/out.Realize that the switch cubicle inner breaker can not enter into the service position after test position is closed a floodgate; When the switch cubicle inner breaker closes a floodgate operation in the service position, can't be with deactivate five anti-chain requirements of position of circuit breaker.
The controlling organization that can control circuit-breaker switching on-off is set in the chassis of circuit breaker cart.Interstage sleeve of design in circuit breaker leads in/out handle hole makes to lead in/out operating grip and only after interstage sleeve is pushed to certain position, could insert in the handle hole circuit breaker cart is led in/out operation.A turning block that links with the divide-shut brake controlling organization is set below the interstage sleeve.Drive the action of divide-shut brake controlling organization when slide block turns to when stoping the position that the handle hole interstage sleeve is pushed into, make circuit breaker can carry out divide-shut brake; Drive the action of divide-shut brake controlling organization when slide block turns to when not stoping the position that the handle hole interstage sleeve is pushed into, limiting circuit breaker closes a floodgate when making circuit breaker carry out sub-switching operation.
Formed like this and want to make breaker closing just must slide block be turned to the position that stops the handle hole interstage sleeve to be pushed into, and then can not operating grip have been inserted handle hole, can not lead in/out operation circuit breaker cart; Want circuit breaker cart is led in/out operation, just must slide block be turned to the position that does not stop the handle hole interstage sleeve to be pushed into, drive the action of divide-shut brake controlling organization, limiting circuit breaker closes a floodgate when making circuit breaker carry out sub-switching operation.
Spring divides and lock operating mechanism bottom mechanism for mounting push rod.This is a known technology, so repeated description not.
Its advantage is:
Independent divide-shut brake control structure and turning block interlock control circuit-breaker switching on-off is set and leads in/out the handle hole interstage sleeve chain, avoided handcart in the operating process of advancing, to make the destabilizing factor of breaker open operation, the Circuits System operation is safer.Circuit breaker cart is provided with turning block, the handle hole interstage sleeve, and to the locking of handle hole interstage sleeve control, and then control leads in/out handle and inserts the handle hole rival car and lead in/out operation through turning block.Make chain more safe and reliable.
