Description
Technical Field
The utility model relates to an electric power infrastructure field specifically is an improve positioning accuracy's isolation switch operating device.
Background
In the power industry, effective adjustment and positioning measures after the high-voltage isolation disconnecting link of electrical equipment is operated are very important.
In actual operation and maintenance, an operator uses an old-fashioned isolation switch with incomplete adjusting and positioning measures to operate, reliable locking is not available after the switch operation is completed for many times in work, electric arc discharge is caused due to the fact that moving and static contacts are separated by electric power, and the accident that nearby personnel are damaged due to equipment burning is caused.
Disclosure of Invention
The utility model aims at providing an improve positioning accuracy's isolation switch operating device in order to solve the problem that traditional isolation switch positioning accuracy is not enough to easily take place dangerous accident when leading to the operation.
The utility model has the following concrete scheme: the utility model provides an improve positioning accuracy's isolation switch operating device, includes the transmission case, and the input of transmission case is equipped with a drive shaft, is equipped with an action bars on the drive shaft, and the action bars is perpendicular with the drive shaft, and rotatory action bars drives the drive shaft and realizes the switch deciliter, be equipped with separating brake position jack and closing position jack in the drive shaft, the last fixed bolster that is equipped with of transmission case is equipped with the pinhole, is equipped with the bolt in the pinhole, the bolt with separating brake position jack matches the separating brake position that is used for locking the drive shaft, the bolt with closing brake position jack matches the closing brake position that is used for locking the drive shaft.
Still be equipped with the pressure spring in the fixed bolster, the pressure spring is used for pushing up the bolt tight to separating brake position jack or closing brake position jack direction.
Bolt outer end is equipped with a jam plate, is equipped with lockhole A on the jam plate, correspond lockhole A position on the fixed bolster and be equipped with lockhole B, be equipped with a safety lock in lockhole A and the lockhole B, lockhole A and lockhole B intercommunication when the bolt inserts branch floodgate position jack or closing position jack.
Be equipped with the backstop round pin on the action bars and be used for restricting the degree of depth that the action bars inserted the drive shaft.
The working principle of the utility model is as follows: when the switching-off or switching-on operation is required, the safety lock is firstly released, then the plug pin is pulled out, meanwhile, the operating rod is operated to rotate the driving shaft, the jack and the plug pin are staggered, the plug pin is loosened, and when the driving shaft rotates to the switching-off or switching-on position, the plug pin is automatically pushed into the jack locking position under the pushing of the pressure spring.
The utility model discloses following beneficial effect has: when the opening or closing is operated, the opening position or the closing position is more accurately positioned, and accidents caused by poor contact of the disconnecting link due to insufficient opening or closing or passing can be avoided.
