Description

Fault Indicator Continuous Quick Removal Device

technical field

The utility model relates to an auxiliary tool for an electric power system, in particular to a continuous and rapid removal device for a fault indicator, which belongs to the technical field of electric power distribution.

Background technique

In order to reduce the difficulty of finding the fault point of the power line and improve the maintenance efficiency, the power line is equipped with a short-circuit fault indicator. After a period of use, the short-circuit fault indicator often needs to be removed and replaced due to various reasons such as aging and failure. In current work, there is a lack of dismantling tools that can be continuously, quickly, conveniently and live-worked.

The existing short-circuit fault indicator removal tools produced by a few manufacturers have the disadvantages of old-fashioned and single structure, insufficient comprehensive performance of materials, easy electrochemical aging, brittle damage after long-term on-site use in cold winter, weak mechanical properties, and short service life.

There are a large number of fault indicators installed on the distribution line of the power system. The existing removal tools can only be removed one by one. The removal speed is slow, the operation efficiency is low, and it is very inconvenient to use. It cannot meet the needs of large-scale removal and replacement Existing technical issues.

The utility model aims at the problems existing in the above-mentioned prior art, and provides a fault indicator continuous and rapid dismantling device, which solves the problems of slow dismantling speed and low working efficiency in the prior art.

The technical scheme of the utility model is as follows:

The fault indicator continuous and rapid removal device includes a connection end, a removal rod and a buffer support. The bottom end of the removal rod is fixed on the upper part of the connection end. There are at least four removal rods, and at least four removal rods enclose an open In the accommodating space, disassembly clamps are provided on at least the tops of the two disassembly rods oppositely arranged; a buffer support is provided above the connection end, and the lower part of the connection end is movably connected with the insulating operation rod.

The lower part of the dismounting rod is provided with an auxiliary support rod, and the auxiliary support rod is fixed on the connecting end.

The dismantling rod is L-shaped.

The auxiliary support rod is V-shaped.

The dismantling rods are evenly spaced.

The height of the dismantling rod is greater than that of the three-phase fault indicator.

The disassembly clip is a barbed structure.

The buffer support is a spring.

The lower part of the connecting end is a cavity, the inner wall of the cavity is provided with internal threads, and the internal threads match the external threads of the insulating operating rod.

The advantages and effects of the present utility model are as follows:

(1) The clamping part at the upper end of the removal rod mainly uses a barb structure, which can continuously remove the short-circuit fault indicator of each phase of the power system distribution line, which is convenient for the disassembly of the fault indicator. The overall structure is simple and integrated, and it is practical powerful.

(2) The disassembly rod forms an open storage space, which has a large storage function and can accommodate three-phase fault indicators at the same time. After the three phases are removed, they can be squeezed out from the side port of the disassembly rod, which is very convenient to take out , which saves working time, meets the needs of large-scale replacement of short-circuit fault indicators of power system distribution lines, and greatly improves the work efficiency of operators.

(3) Strong versatility, the internal thread at the lower part of the connection end matches the size of the insulating rod, and can be connected to the insulating rod for use.

(4) The disassembly of the short-circuit fault indicator can be carried out without power failure of the line, so as to realize high-altitude live working, which is safe and reliable; the structure is exquisite and smooth, compact and firm, and has strong mechanical performance, adapting to various seasons and harsh natural environments Conditions; low cost, good economic benefits and practical value, suitable for large-scale promotion and use.
