Abstract
The utility model relates to an assembler for rapidly disassembling and assembling high-voltage segregate switch contacts, which belongs to a special tool of electrical operation of a power supplying and distribution system and mainly comprises a thrust screw bolt (1), a thrust screw bolt movable top (2), bearings (4) and bearing racks (7), a thrust screw bolt base (3), a bottom board (6) and the like. The assembler selects required number of the bearings to sleeve on an upright stanchion according to the contact index of a high-voltage isolating switch contact. The thrust screw bolt enables the top to push a contact finger rack to enable to move, and the natural bending of the contact finger and the pushing force of the thrust screw bolt are used to enable the contact finger to open, a fixed screw is screwed off, thereby the maintenance or the assembling work of the high-voltage isolating switch contact, and the products of the utility model have the advantages of simple structure, low manufacturing cost, convenient carry, safe operation and rapid speed.
Description
Technical field
The utility model belongs to the electric power operation specific purpose tool of power supply, distribution system, particularly a kind of assembly appliance that keeps in repair high voltage isolation switch contact.
Technical background
High voltage isolator be used for branch, close the no load condition circuit, safety is isolated repair apparatus and change-over circuit, and can pass through rated current reliably in running status.Present 35kV and above electric pressure high voltage isolator, it is the maximum electric equipment of power industry consumption, its structure is to be assembled by fingertip, tension spring, support and fingertip seat etc., the operation principle of its contact is: provide the contact pressure of fingertip and fingertip seat and cylindrical contact by spring, guarantee that its contact is good.The fingertip that is distributed in a cylindrical pillars both sides during combined floodgate contacts with cylindrical contact is electric, the contact site only limits to the contact both sides, thereby contact wire often becomes the principal element of restriction contact ampacity, therefore contact is subjected to the influence of external environment condition when current-carrying moves, for example dust and high temperature etc. very easily cause the contact heating, constitute bridge circuit because of the contact of fingertip and spring on the other hand, the fingertip resistance unbalance increases, and causes that contact is overheated to be burnt.Therefore, the accident probability height that is in operation, the repair and maintenance workload is big, and power department need drop into that great amount of manpower and material resources is overhauled and periodic maintenance.When repair and maintenance, contact is disintegrated and assemble.Because this modular construction is special, at present, electric power system all is the manual dismounting of carrying out to its repair and maintenance, existence overcomes the spring force difficulty and the fingertip support is as easy as rolling off a log crooked, therefore is difficult to it is fixed, cause assembling or dismounting not only to require great effort but also time-consuming, intensity of workers is big, in operating process, because misoperation also can cause spring or fingertip to damage.Technical problem to be solved in the utility model just provides the dismounting utensil of a kind of present repair and maintenance 35kV and above electric pressure high voltage isolation switch contact.
Summary of the invention
For the high voltage isolation switch contact repair and maintenance that overcomes present 35kV and above electric pressure needs the manual dismounting of carrying out, the fingertip support is difficult to fix, damage spring and fingertip easily, the problem that intensity of workers is big, the utility model provide the utensil of a kind of high voltage isolation switch contact maintenance without hand disassembly and assembling.
The scheme that the utility model employing technology solves is: a kind of assembler of fast assembling-disassembling high voltage isolation switch contact, mainly by thrust screw rod (1), the movable top of thrust screw rod (2), the pressing plate (7) of rolling bearing (4) and rigid bearing, thrust screw rod pedestal (3) and base plate (6) constitute, it is characterized in that: thrust screw rod pedestal (3) is fixed on the base plate (6), thrust screw rod (1) is screwed in the thrust screw rod pedestal (3), rolling bearing (4) is fixed on the support of bearing (9), again according to the fingertip number of high voltage isolation switch contact (10), select the bearing (4) of requirement, bearing holder (housing, cover) is contained in vertical rod (8) goes up formation two string bearing group, be separately fixed on the block plate (6) according to certain size with thrust screw rod (1), the activity top (2) of thrust screw rod promotes fingertip support (12) and moves, utilize the natural torsion part of fingertip (10) and the top power of thrust screw rod (1) to make the fingertip (10) that hangs up tension spring open; Rolling bearing (4) assurance fingertip (10) is exempted from damage, and not crooked in guiding fingertip (10) and support (12) moving process.Back out the hold-down screw of fingertip support (12), easily extract the fingertip seat, or insert the fingertip seat smoothly, tighten hold-down screw, thereby finish the dismounting or the assembling of high voltage isolation switch contact.
It can make the electrician easily finish dismounting and assembling to high-voltage switch contact, guarantees the excellent of each part of high voltage isolation switch contact, increases work efficiency, and improves practitioner's working condition, and can reduce the production cost of application industry.This product structure is simple, and low cost of manufacture is easy to carry.
The beneficial effects of the utility model are: utilize 220kV high voltage isolation switch contact of manual dismounting to need one time of two people, use this product one people only to need about 20 minutes, and easily finish in operating process.
