Description
Technical field
This utility model relates to high voltage electric equipment anti-misoperation technical field, is specifically related to a kind of high-tension switch cabinet isolation
Switch and earthed switch interlock error operation proof mechanism.
Background technology
The high-tension switch cabinet of power supplying and distributing equipment mainly by operating elements such as vacuum circuit breaker, disconnecting switch, earthed switches, with
And transformer etc. is measured, protection element composition current supply circuit.The power transmission of high-tension switch cabinet or power-off are generally by isolator operation
The operating mechanism of mechanism and earthed switch completes, and give, disconnecting switch and earthed switch operation in power-off and maintenance process
The frequency is the highest.According to the requirement of safety regulation for operations, must could will keep apart close first by grounding switch tripping during power transmission
Lock；Otherwise, first disconnecting switch must be in separating brake during power-off, then earthed switch could be closed a floodgate.In conventional art, high pressure
The isolator operating mechanism of switch cubicle and the operating mechanism of earthed switch are usually separate split-type structural, although adopting
With there being anti-misoperation measure, but not only there is volume greatly in this structure, installs the defects such as complicated, inconvenient operation, and anti-error
Poor reliability, is susceptible to maloperation and causes the accident such as device damage or casualties, and safety is the most poor.At present, though
So have five anti-interlocking integrated techniques or disconnecting switch and grounding switch interlocked operation technology, but mostly there is structure more
The shortcomings such as complexity, operation underaction or reliability are poor.
CN204792537U discloses a kind of operating mechanism for high voltage switch cabinet, and it is by earthing switch operating mechanism and isolation
Switch operating mechanism concentrates in same box body, adds can the second rotating shaft blocked in earthing switch operating mechanism
Two baffle plates, add the first baffle plate that can the first rotating shaft be blocked in isolator operating mechanism, and operate at earthed switch
The slide plate that the second rotating shaft or the first rotating shaft can be implemented alternately to block is added between mechanism and isolator operating mechanism.This skill
Although art is it can be avoided that cause a serious accident because of operation sequence error, and can ensure that the correctness of operation order, improve interlocking
The reliability of function, but main member and structure reach 37 more than, and its structure is the most complicated, and making, installation workload are relatively big, and
The reduction of its volume is the most extremely limited.
Utility model content
It is anti-with earthed switch interlocking that problem to be solved in the utility model is to provide a kind of high-voltage switch cabinet isolation switch

Described two driver plates are respectively equipped with locking boss, and respectively with two clutch plate weeks the fit depressions that arranges of side, be used for
Realize the locking of disconnecting switch and grounding switch tripping or "on" position.
Described operation axle and output shaft are connected with switch cubicle inwall by support plate.
The beneficial effects of the utility model are:
1) lock misoperation-proof mechanism of the present utility model uses self-align concentric preset program mode hand-operated structures, suitable
Load onto the miniaturization fixed switchgear of isolation/lower ground connection for wearing side, this mechanism is simple to operate, and operator can disposably connect
Having continued the operation of isolation/lower ground connection, need not operate by substep branch in a traditional way, upper isolation/lower ground connection can be by machine
Structure internal blas successively action, meets " five prevent " requirement, and simple in construction, and component is few, easy for installation, and overall dimensions is little,
(this mechanism can be placed conveniently within the crossbeam between middle door and Xiamen, outside to be not necessary to take the useful space of switch cubicle width
Only set handle hole for deciliter operation just can, the Facad structure that enormously simplify switch cubicle is arranged), switch cubicle broad-ruler can be made
Very little it is reduced to 600MM；
2) by locking the setting of boss, the first clutch plate or second is driven respectively when the first driver plate or the second driver plate rotate
After clutch plate rotate in place, the first locking boss or the second locking boss go to and the first groove or the second fit depressions respectively
Position, when the first clutch plate or the second clutch plate are rotated further, the first clutch plate or the second clutch plate are not rotated further by, Er Qieyou
Boss and the first groove or the inhibition of the second groove fit is locked in the first locking boss or second, no matter the first clutch plate
Or second clutch plate or the first output toggle arm or the second output toggle arm by any external force also will not action, be achieved in isolation
Switch and grounding switch tripping or the locking of "on" position.
