Abstract

The utility model relates to electric power maintenance tools. An existing centrally installed switchgear in the electric power field drops easily and has potential safety hazards. The solution adopted is that the isolation tool for maintaining the 10kV centrally installed switchgear comprises a baffle plate used for isolating an electrified part, the baffle palate is provided with a supporting arm, the supporting arm comprises rack-shaped upper and lower arms, a gear is connected between the upper arm and the lower arm, and the gear drives the upper arm and the lower arm to move horizontally toward the opposite directions so as to support at two sides of the switchgear. According to the utility model, the upper arm and the lower arm can be driven by rotating the gear to move horizontally along the baffle plate, and the upper arm and the lower arm move away from each other and support at the two sides of the switchgear, thereby isolating the electrified part.

Description

The mid-cabinet maintenance of 10kV isolating tool
Technical field
The utility model relates to a kind of mid-cabinet maintenance instrument.
Background technology
At present, there is serious potential safety hazard in the maintenance position in the isolation baffle plate of the mid-cabinet of most of transformer station under the situation of bus operation, checks and disappear to cause when lacking that isolating baffle plate opens, and has Danger Electric shock risk in carrying out cabinet.All expose outside owing to isolate the running part of baffle plate, the possibility that touches running part and the isolation baffle plate is opened is arranged when maintenance.
The utility model content
The technical problem that the utility model solves provide a kind of safe, the get an electric shock mid-cabinet maintenance isolating tool of hidden danger of live line working personnel has been blocked, has eliminated at charged position in the cabinet.
Its technical problem that solves the utility model adopts the mid-cabinet maintenance of following technical scheme: 10kV isolating tool, comprise the baffle plate of isolating charged position, described baffle plate is provided with support arm, described support arm comprises upper arm and the underarm of spline-simulating, be connected with gear between described upper arm and the underarm, described gear driven upper arm and underarm move horizontally support in the opposite direction in the switch cubicle both sides.
Further technical scheme is: described baffle plate is provided with stationary magazine creel, and described support arm is located at also can moving axially along stationary magazine creel in the stationary magazine creel.
Further technical scheme is: described stationary magazine creel is fixed on the described baffle plate by back-up block.
Further technical scheme is: described gear is provided with rotating shaft, and described baffle plate is provided with the axis hole of the described rotating shaft of cross-under.
Further technical scheme is: described baffle plate is provided with the axle bed of supporting revolving shaft, and described rotating shaft is provided with lockhole, and described axle bed is provided with positioning through hole, articulates the micro_computer five_proof lock on described lockhole and the positioning through hole and makes gear not rotate.
Further technical scheme is: described rotating shaft is passed axle bed and is connected with rotating disk.
Further technical scheme is: the end of described support arm is provided with supporting seat.
Further technical scheme is: described supporting seat is the elastomer that flexible material is made.
The beneficial effects of the utility model are: it is laterally mobile along baffle plate that transmitting gear can drive upper arm and underarm, upper arm and underarm mutually away from, strut in the switch cubicle both sides, isolate charged position.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is front view of the present utility model;
Fig. 2 is right view of the present utility model.
Embodiment
With reference to figure 1 and Fig. 2, shown in the mid-cabinet of the utility model 10kV maintenance isolating tool, comprise the baffle plate 1 of isolating the charged position of mid-cabinet, described baffle plate 1 is provided with two support arms, described support arm comprises upper arm 31 and the underarm 32 of spline-simulating, be connected with gear 2 between described upper arm 31 and the underarm 32, described transmitting gear 2 drives upper arm 31 and underarm 32 moves horizontally support in the opposite direction in the switch cubicle both sides.
The fixed form of support arm and baffle plate: at described baffle plate 1 stationary magazine creel 4 is set, described support arm is located in the stationary magazine creel 4 and can moving axially along stationary magazine creel; Described stationary magazine creel 4 is fixed on the described baffle plate 1 by back-up block 5, can back-up block 5 be fixedlyed connected with baffle plate 1 by screw.
Be provided with rotating shaft 21 at described gear 2, described baffle plate 1 is provided with the axis hole of the described rotating shaft 21 of cross-under, make rotating shaft and workpiece on the not coplanar of baffle plate, the running part that backboard is installed can not expose outside, prevents from because touching running part the isolation baffle plate being opened when maintenance.Described rotating shaft 21 is passed axis hole and is connected with the rotating disk of being convenient to rotate 22, and rotating disk is arranged on the end of rotating shaft, is fixed as one with rotating shaft, can resilient sleeve be set in sabot.
For preventing this mid-cabinet maintenance misoperation of isolating tool, be provided with the axle bed 11 of supporting revolving shaft 21 at described baffle plate 1, be provided with the lockhole 7 that connects described rotating shaft 21 and axle bed 11, articulating the micro_computer five_proof lock on the described lockhole 7 makes gear not rotate, have only the workmen just can open five anti-locks, take out isolating tool, prevent under unmanned situation being opened by other people and cause workmen's contingency.
The two ends of above-mentioned upper arm 31 and underarm 32 are equipped with supporting seat 6, need not distinguish during rotary turnplate 2 to turn to, and by supporting seat 6 baffle plate are supported in the switch cubicle; The elastomer that described supporting seat 6 is made for flexible material fits tightly by elastomer and sidewall when support arm and main switch cabinet sidewall clamp, and strengthens active force, and the shrinkage of elastic component can guarantee that the lockhole 7 on rotating shaft 21 and the axle bed 11 is communicated with.
Those skilled in the art can make various changes and distortion to the utility model after knowing principle of the present utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
