Abstract
The utility model discloses a grounded misoperation-preventive locking device of a 10kV centrally installed switchgear, and relates to the field of electric power. An existing centrally installed switchgear is lack of a misoperation-preventive device and has potential safety hazards. The novel technical solution is that the grounded misoperation-preventive locking device comprises a base and a bolt disposed on the base, wherein the base is mounted beside an operating hole of a grounding switch; the bolt can move around the base to cover or expose the operating hole; a retaining plate in the operating hole can abut against the side wall of the bolt; the bolt is provided with a locking member which keeps the bolt to cover the operating hole of the grounding switch; and the retaining plate in the operating hole of the switch can be operated by turning over the bolt only after the locking member is opened.

Its technical problem that solves the utility model adopts the mid-cabinet ground connection of following technical scheme: 10kV anti-misoperation locking device, comprise the base that is installed in earthed switch handle hole one side and the latch that is located on the base, described latch can block the earthed switch handle hole or exposes around base upset, the sidewall of described latch can prop up the baffle plate in the earthed switch handle hole, and described latch is provided with the locking member that keeps latch to block the earthed switch handle hole.
Further technical scheme is: described base is provided with rotating shaft, and described latch is provided with the axis hole that connects rotating shaft.
Further technical scheme is: described latch is provided with connecting axle, and described base is provided with axle bed.
Further technical scheme is: described locking member comprises the Connection Block that is located on the earthed switch handle hole opposite side, and described latch connects described Connection Block.
Further technical scheme is: described Connection Block is provided with lock dog, and described lock dog is provided with through hole, and the end of described latch is provided with the groove of cross-under lock dog, and described lock dog passes groove and articulate the micro_computer five_proof lock in through hole.
Further technical scheme is: the end of described latch is provided with lockhole, described Connection Block is provided with the positioning through hole consistent with described lockhole aperture, and described micro_computer five_proof lock passes lockhole and the positioning through hole dead bolt makes latch keep blocking the earthed switch handle hole.
Further technical scheme is: described latch is provided with handle.
Further technical scheme is: be provided with installing hole away from earthed switch handle hole one end on described base and the Connection Block.
The beneficial effects of the utility model are: described latch can block the earthed switch handle hole or exposes around base upset, the sidewall of described latch can prop up the baffle plate in the earthed switch handle hole, described latch is provided with the locking member that keeps latch to block the earthed switch handle hole, only after locking member is opened, the baffle plate of upset latch in could the console switch handle hole.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment
With reference to figure 1, shown in the mid-cabinet ground connection of the utility model 10kV anti-misoperation locking device, comprise the base 2 that is installed in earthed switch handle hole 5 one sides and the latch 1 that is located on the base, described latch 1 can block earthed switch handle hole 5 or exposes around base 2 upset, the sidewall of described latch 1 can prop up the baffle plate 6 in the earthed switch handle hole 5, and described latch 1 is provided with the locking member that keeps latch 1 to block earthed switch handle hole 5.Described locking member comprises the Connection Block 3 that is provided with on earthed switch handle hole 5 opposite sides, and described latch 1 connects described Connection Block 3.
The substitute mode of base and latch: described base 2 is provided with rotating shaft 21, and described latch 1 is provided with the axis hole that connects rotating shaft 21.Perhaps described latch 1 is provided with connecting axle, and described base 2 is provided with axle bed, is provided with the handle of being convenient to operate 11 in described latch 1 end.
With reference to figure 1, embodiment 1: the end of described latch 1 is provided with lockhole 4, described Connection Block 3 is provided with the positioning through hole consistent with described lockhole 4 apertures, lockhole was connected with positioning through hole when latch 1 blocked earthed switch handle hole 5, and the micro_computer five_proof lock passes lockhole and the positioning through hole dead bolt makes latch keep blocking the earthed switch handle hole.
With reference to figure 2, embodiment 2: described Connection Block 3 is provided with lock dog 7, the side of described lock dog 7 is provided with through hole, the end of described latch 1 is provided with the groove of cross-under lock dog 7, lock dog 4 passed groove when latch blocked the earthed switch handle hole, articulates the micro_computer five_proof lock and make latch keep blocking the earthed switch handle hole in through hole.
Be provided with base installing hole 22 and Connection Block installing hole 31 away from earthed switch handle hole one end on above-mentioned base 2 and the Connection Block 3, by screw base fixedlyed connected with mid-cabinet with Connection Block.
During the earthed switch separating brake, the baffle plate in the earthed switch handle hole is positioned at the upper end of earthed switch handle hole in the raw, and latch keeps off on the earthed switch handle hole, has articulated the micro_computer five_proof lock, and latch can not arbitrarily move, and the earthed switch handle hole can not be operated.If will operate ground connection switching manipulation hole, need to such an extent that untie the micro_computer five_proof lock, latch is opened from the earthed switch handle hole, just baffle plate can be left behind and operate.
