Description
Technical field
The utility model relates to insulating shield technical field more particularly to a kind of grid switching operation club head insulating shields.
Background technique
Grid switching operation, which refers to, is transformed into the system that another working condition is carried out from a kind of working condition for electrical equipment
Column operation, required during the operation and maintenance of 10 daily KV line electrical equipments carry out grid switching operation, 10,000
The common tool of hint road electrical equipment grid switching operation is back brake operating lever, in falling for daily 10 KV line electric equipment operation
Light is bad when in lock operating process due to disconnecting switch rust card, operation, and dust storm is larger etc. is not easy in the environment of grid switching operation
Back brake operating lever metal club head, which accidentally touches disconnecting switch pedestal, causes the metab of disconnecting switch and the moving contact of disconnecting switch to lead to
The metal club head for crossing back brake operating lever is connected, and the single-phase grounding fault caused by influences the safe operation of power grid, is endangered
The person and the electrical equipment safety of route.
Utility model content
Purpose of the utility model is to solve metal club heads existing in the prior art accidentally to touch disconnecting switch pedestal, causes
The shortcomings that making single-phase grounding fault, and a kind of grid switching operation club head insulating shield proposed.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of grid switching operation club head insulating shield, including shield casing, the shield casing are set in the back brake behaviour
Make on bar, the internal preset of the shield casing has cavity, the default sealing in one end of shield casing, and the other end of shield casing connects
It is connected to adjustable joint, the internal run-through of the adjustable joint, and adjustable joint and one end of shield casing is provided with import, the cavity
Inside be placed with support bar, the support bar is arranged in the shape of a spiral on the inner wall of the cavity.
Preferably, the material of the shield casing and adjustable joint is rubber, and rubber material at least selects EPDM
Rubber.
Preferably, the material of the support bar is plastics.
Preferably, the tube wall of the adjustable joint is raised outward and draws arc groove, and the support bar extends to the work
The inside of adapter tube, and support bar is arranged in the shape of a spiral on the inner wall of the arc groove.
Preferably, pass through loose joint tear tape pair between the pipe end of the shield casing and the pipe end of the adjustable joint
Connect fixation.
The beneficial effects of the utility model are:
1, grid switching operation club head insulating shield may be implemented not increase staff, not increase mechanical equipment, not change
On the basis of operating environment, the disconnecting switch for avoiding using operating stick to cause due to mistake during grid switching operation can be played
Single-phase grounding fault caused by metab and the moving contact of disconnecting switch are connected by the metal club head of back brake operating lever,
So having very strong feasibility.
2, grid switching operation club head insulating shield is the adapted components that back brake operating lever newly adds, it is only necessary to be used at present
Grid switching operation club head install wear, do not need to eliminate back brake operating lever used at present or disconnecting switch, popularization makes
Used time has the characteristics that economical and efficient, convenient for popularization.
To sum up, present apparatus structure is simple, novel in design, is avoided that during grid switching operation since mistake causes single-phase connect
It is the case where ground short circuit failure, and high financial profit, practical, convenient for promoting the use of.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-4, a kind of grid switching operation club head insulating shield, including shield casing 1,1 shroud casing 1 of shield casing
Material with adjustable joint 3 is rubber, and rubber material at least selects ethylene propylene diene rubber, and the material of support bar 6 is plastics, living
The tube wall of adapter tube 3 is raised outward and draws arc groove 5, and support bar 6 extends to the inside of adjustable joint 3, and support bar 6 is helically
Shape is arranged on the inner wall of arc groove 5, is torn between the pipe end of shield casing 1 and the pipe end of adjustable joint 3 by loose joint
The docking fixation of item 7 is located on back brake operating lever 8, and the internal preset of shield casing 1 has cavity 2, and one end of shield casing 1 is preset close
Envelope, the other end of shield casing 1 are connected with adjustable joint 3, the internal run-through of adjustable joint 3, and adjustable joint 3 far from shield casing 1
One end is provided with import 4, and the inside of cavity 2 is placed with support bar 6, and support bar 6 is arranged in the shape of a spiral on the inner wall of cavity 2,
Shield.
In the present embodiment, in conjunction with Figure of description, the utility model is suitable for daily 10 KV line electric equipment operation
Grid switching operation during, it is bad to be particularly suitable for light when disconnecting switch rust card, operation, under the adverse circumstances such as dust storm is larger
Grid switching operation, installation method is portable, only the shield casing 1 of grid switching operation club head insulating shield need to be mounted on back brake operating lever
In 8 head, when back brake operating lever 8 is touched in the bottom end of adjustable joint 3, shield casing 1 is firmly pulled down, so that adjustable joint
3 deformations, arc groove 5 squeezes outward, in this way, one pressure is gradually increased, shield casing 1 is covered will completely in back brake operating lever
On 8, second, adjustable joint 3 is since deformation, loose joint tear tape 7 are ripped, adjustable joint 3 falls off from shield casing 1, and adjustable joint 3 deforms
Later, bore increases, and abjection adjustable joint 3 can be then taken out from shield casing 1, and outside the support bar 6 of 3 inside of adjustable joint
Dew, then extract support bar 6 out, in this way, final 8 head insulating shield casing 1 of back brake operating lever is wraps closely about in head.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
