Description
Technical field
The invention belongs to power equipment earth connection technical field.
Background technology
High-voltage grounding wire is in circuit and Substation construction, during for preventing from closing on electrified body generation electrostatic induction electric shock or false switching, ensures the use of safety.High-voltage grounding wire has split-phase type and the large class of composite type two, and line card divides spring compression type and spiral two large classes.Wherein the flat mouth line card of spiral compression formula is applicable to the use of interruption maintenance in copper, aluminium row's bus and cubicle switch cabinet, and spring compression type (two-man act bayonet type) is applicable to the use of 500 kilovolt interruption maintenances.Short-circuit grounding wire is made up of insulating bar, wire clamp, short-circuit line, earth connection, the auspicious son of ground connection, the folder that confluxes, earth clip, often overlaps three groups, and often group is linked into an integrated entity by conductor wire end line card, short-circuit line and earth terminal line card.Press regulations stipulate first electrical verification during use, after confirmation has a power failure, first by earth wire clip, be fastened on earth electrode, then press dead line electric pressure, selected hook stick, hangs over wire card on wire.
In the work of current electric grid grid switching operation, part bus goes between, main transformer aluminium row and lead-in wire, main feed lock lead-in wire, circuit line and capacitor, PT connecting line installation position is higher, simultaneously with the super phenomenon such as thick of mounting position ultra-wide, existing earth connection attaching tool one is adopted to be grounding wire connector may be caused to come off in handling journey to hurt sb.'s feelings, two is that in dismounting earth connection process, grounding wire connector may rotate with brake pull-rod power thrusts, cause dismounting difficulty, three is that work is complete, should first remove wire card, rear dismounting earth wire clip, operating process is very loaded down with trivial details, waste the extensive work time.
Through retrieval, application number be 201120563025.4 patent relate to a kind of can quick despatch high-voltage grounding wire clamp, this wire clamp is by being connected by push-and-pull connecting rod between handle with metal block, and composition slide block mechanism, for clamping high-tension bus-bar.This structure clamps high-tension bus-bar only by chuck and fixed mount, and reliability is not high, easily falls or wire clamp occurs to rotate and operating difficulties with pull bar.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of high-voltage grounding wire safety loading device, this apparatus structure is simple, easy to operate, safety, and reliability is high, the falling from high altitude produced in earth connection cargo handling process and the problem causing operating difficulties with brake pull-rod rotation can be stopped, improve the efficiency of earth connection handling.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of high-voltage grounding wire safety loading device, it is characterized in that the hollow insulating sleeve comprising insulation, chuck, pull bar and operating trigger thereof, the inside, one end of described insulating sleeve is provided with chuck, the other end of insulating sleeve is provided with operating trigger and back-moving spring thereof, insulating sleeve inside is provided with the pull bar of connecting clip and operating trigger, described chuck comprises permanent joint, stator and hook, described permanent joint inside is hollow, permanent joint end is provided with leg-of-mutton stator, three limits of stator are hinged with three open-close type hooks respectively, the other end of permanent joint is connected with pull bar.
Said structure is described further, described operating trigger outside be provided with for the protection of framework, one end of operating trigger and frame articulation, the other end of operating trigger enters the inside of insulating sleeve, and is connected with pull bar.
Said structure is described further, in the junction of operating trigger and pull bar, is provided with release-push.
Be described further said structure, the tail end of described insulating sleeve is also socketed with the handle of insulation.
The beneficial effect adopting technique scheme to produce is:
The present invention is the operation tool in the work of a kind of electrical network grid switching operation, be connected with stator by arranging three hooks, utilize operation spanner fluctuation pull bar, drive hook folding, earth wire loads and unloads, earth connection can be stopped install and the contingent phenomenon of hurting sb.'s feelings that comes off in unloading process at all, eradicate the dismounting difficulty situation of removing earth connection point in earth connection process and causing with the rotation of brake pull-rod simultaneously, fail safe and the operating efficiency of handling high-altitude earth connection can be improved simultaneously; Structure of the present invention is simple, easy to operate, safety, and reliability is high, and operability is good, utilizes release-push can realize fast discharging hook, increases work efficiency.
