Abstract
This utility model discloses a special fixing tool for preventing mistakenly opening a brake during a process of switch maintenance, comprising hooks and tension springs. Two ends of the spring are connected to the hooks; a pulling ring is positioned on the outside wall of one of the hooks; the number of the drawing force springs is two; and an insulation hand protection rubber pad is positioned on the pulling ring. The special fixing tool for preventing mistakenly opening the brake during the process of switch maintenance is selectively fixed on a small pull rod of an isolation switch and a base of the isolation switch to fixed the isolation switch at the position where the brake is opened to pass a dead point and the normal maintenance and disassembling of the isolation switch are not affected. As a result, the special fixing tool for preventing mistakenly opening the brake during a process of switch maintenance can solve the safety hazard that the isolation switch can open to hurt people during the processes of maintenance and disassembling.
Description
technical field:
The utility model relates to a kind of fixing specific purpose tool, particularly relates to a kind of isolating switch and overhauls the fixing specific purpose tool of anti-error separating brake.
background technology:
High voltage isolator is widely used in electrical production at present, large-scale substation isolating switch is used more, especially after batch production maintenance is carried out, isolating switch maintenance will enter a new stage, isolating switch runs to after certain state, can carry out a deep decomposition maintenance, because current isolating switch generally adopts counter spring structure, at open position spring, will be to enter factory's maintenance with energy storage state, and removing after the fixing anchor ear of upper and lower conductive arm, disconnecting link state will be difficult to control, very easily release pressure of balancing spring, bullet wound operating personnel separately, heavy fatal, operating risk is very big.
utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple and practical, can prevent that the isolating switch that separating brake surprisingly trips from overhauling the fixing specific purpose tool of anti-error separating brake.
The technical solution of the utility model is: a kind of isolating switch overhauls the fixing specific purpose tool of anti-error separating brake, comprises hook and tension spring, and the two ends of described spring are connected with a described hook respectively, links up with described in one of them a draw ring is set on lateral wall.
Described tension spring is two; On described draw ring, be provided with insulation handguard rubber cushion.Described hook is arc or L shaped, and described hook adopts rivet to be connected with described draw ring.
The beneficial effects of the utility model are:
1, the utility model is selected to be fixed on isolating switch lower link bar and isolating switch base, isolating switch is fixed on to separating brake and crosses dead-centre position, the normal maintenance that does not affect isolating switch is decomposed, and has better solved the potential safety hazard of easily separately hurting sb.'s feelings in isolating switch maintenance decomposable process.
2, the utility model adopts hook as fixture, effective, easy to operate, and between two hooks, adopt tension spring to connect, when thering is good flexibility ratio and pulling force, also there is certain tensile elongation, can be applicable to various isolating switches, handled easily person's operation, thus increase work efficiency.
3, the utility model is simple and practical, is convenient to fixed installation, easy to use, has improved operating efficiency, has eliminated potential safety hazard, and isolating switch is had to broad applicability.
accompanying drawing explanation:
Fig. 1 is the front view that isolating switch overhauls the fixing specific purpose tool of anti-error separating brake.
Fig. 2 is that isolating switch overhauls the fixing specific purpose tool vertical view of anti-error separating brake.
embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, in figure, 1-draw ring, 2-hook, 3-tension spring.
Isolating switch overhauls the fixing specific purpose tool of anti-error separating brake and comprises hook 2 and tension spring 3, and wherein: the two ends of tension spring 2 are connected with a hook 2 respectively, one of them is linked up with a draw ring 1 is set on 2 lateral walls.
As required, tension spring 3 adopts two; On draw ring 1, be provided with insulation handguard rubber cushion.Hook 2 is arc or L shaped, and hook 2 adopts rivet to be connected with draw ring 1.
During maintenance, hook 2 sides are hung on isolating switch bottom tub steel frame, pull draw ring 1 and another is linked up with to 2 sides hang on isolating switch lower link bar, guarantee that isolating switch separating brake crossing dead-centre position, after fixing, can decompose maintenance to isolating switch.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
