Description

A kind of grid switching operation club head insulating shield
Technical field
The present invention 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.
Summary of the invention
The purpose of the present invention is to solve metal club heads existing in the prior art accidentally to touch disconnecting switch pedestal, causes list The shortcomings that phase ground short circuit failure, and a kind of grid switching operation club head insulating shield proposed.
To achieve the goals above, present invention employs following technical solutions:
A kind of grid switching operation club head insulating shield, including shield casing, the shield casing are set in the back brake operating lever On, 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 is connected with Adjustable joint, the internal run-through of the adjustable joint, and adjustable joint are provided with import far from one end of shield casing, the cavity it is interior Portion is placed with support bar, and 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 present invention are:
1, grid switching operation club head insulating shield may be implemented not increase staff, not increase mechanical equipment, not change operation On the basis of environment, the metal for avoiding the disconnecting switch caused due to mistake using operating stick during grid switching operation can be played Single-phase grounding fault caused by pedestal and the moving contact of disconnecting switch are connected by the metal club head of back brake operating lever, so With 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
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
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 present invention is suitable for falling for daily 10 KV line electric equipment operation Back brake in lock operating process, under the adverse circumstances such as light is bad when being particularly suitable for disconnecting switch rust card, operating, and dust storm is larger 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 8 In 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 becomes Shape, arc groove 5 squeeze outward, in this way, one pressure is gradually increased, shield casing 1 are covered will completely in back brake operating lever 8 On, 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 foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
