Abstract
The utility model discloses a padlock for a grounding switch operation mechanism, which comprises a fixed part and a moving part, wherein an operation hole used for accommodating a moving contact operation handle of a grounding switch and enabling the operation handle to rotate in the operation hole is arranged in the middle of the fixed part, connection holes capable of fixing the fixed part on a switch cabinet are respectively arranged above and below the fixed part, a hinge seat is arranged on the left side of the fixed part, a lock buckle protruding out of the surface of the fixed part is arranged on the right side of the fixed part, and the moving part is hinged onto the hinge seat of the fixed part. A lock buckle protruding out of the surface of the moving part is arranged on the side of the moving part opposite to the hinge point of the moving part, and the lock buckle on the moving part is matched with the lock buckle on the fixed part. The padlock for the grounding switch operation mechanism has the advantages that the padlock is suitable for the switch cabinet grounding switch, the moving contact operation handle of the grounding switch can be locked as required during use, misoperation of another operator is avoided, and further safety of the operator is guaranteed.
Description
Technical field
The utility model relates to a kind of padlock, and particularly a kind of earthed switch operating mechanism is used padlock.
Background technology
Switch cubicle is when being in states such as operation, test, maintenance; Circuit breaker and earthed switch then need be in the use of corresponding working position with the compounding practice personnel; If in a single day third party's misoperation takes place this moment, mistake is divided, splice grafting ground switch will cause serious consequence.Existing switch cubicle owing to there is not the special-purpose device that is used to prevent the earthed switch misoperation, therefore often need be equipped with special messenger's nurse when operation, time-consuming, and fail safe is not high.
The utility model content
The purpose of the utility model is to overcome the weak point of prior art, and provides a kind of switch cabinet grounding switch that prevents to be used padlock by the earthed switch operating mechanism of misoperation.
A kind of earthed switch operating mechanism is used padlock; Its structural feature is: comprise fixture and movable part; Described fixture offers at the middle part and is used to hold handle hole earthed switch moving contact lever, that also can rotate within it, below reaching above the fixture, is provided with and can fixture be fixed in the connecting hole on the switch cubicle, is provided with hinge seat in the left side of fixture; Be provided with the snap close that protrudes from the fixture surface on the right side of fixture
Described movable part is articulated on the hinge seat of fixture; Be provided with the snap close that protrudes from the movable part surface with respect to that side of movable part pin joint on the movable part; Snap close on the movable part and the snap close on the fixture are complementary, and described movable part and fixture movable part when being in tightening state partly hides the handle hole of fixture.
In use, utilize connecting hole on the fixture, fixture is fixed on the switch cubicle, and movable part is articulated on the fixture.Then according to the needs of operation, with movable part with respect to fixture locking or open, thereby guarantee operating personnel's safety.
In sum, the utility model is compared the following advantage of prior art:
The utility model being provided with is applicable to the padlock that switch cabinet grounding switch is used, and so in use, just can be as required the moving contact lever of earthed switch be pinned, thereby avoids the third party's misoperation, to guarantee operating personnel's safety.

Embodiment
Below in conjunction with embodiment the utility model is described in more detail.
A kind of earthed switch operating mechanism shown in Fig. 1-5 is used padlock; Comprise fixture 1 and movable part 2; Described fixture offers at the middle part and is used to hold handle hole 11 earthed switch moving contact lever, that also can rotate within it, below reaching above the fixture, is provided with and can fixture be fixed in the connecting hole 12 on the switch cubicle, is provided with hinge seat 13 in the left side of fixture; Be provided with the snap close 14 that protrudes from the fixture surface on the right side of fixture
Described movable part 2 is articulated on the hinge seat of fixture; Be provided with the snap close 21 that protrudes from the movable part surface with respect to that side of movable part pin joint on the movable part; Snap close on the movable part and the snap close on the fixture are complementary, and described movable part and fixture movable part when being in tightening state partly hides the handle hole of fixture.
When switch cubicle in running status following time, circuit breaker is in the service position, earthed switch is at gate-dividing state simultaneously; Handle hole is pinned in earthed switch padlock mechanism, prevent operating personnel's mistake splice grafting ground switch; Reach " five is anti-" forced blocking requirement.
When switch cubicle in trystate following time, circuit breaker is in test position, earthed switch is gate-dividing state (also can in "on" position) simultaneously; Handle hole is pinned in earthed switch padlock mechanism, prevent operating personnel's mistake deciliter earthed switch.
When switch cubicle in inspecting state following time, circuit breaker is in the maintenance position, earthed switch is in "on" position simultaneously; Handle hole is pinned in earthed switch padlock mechanism, prevent operating personnel's mistake branch ground connection switch; Guarantee maintainer's safety.
It is identical with prior art that present embodiment is not stated part.
