Butt joint tool special for GIS

Abstract

The invention discloses a butt joint tool special for a GIS. The tool comprises a clamp body assembly and a support assembly connected to the clamp body assembly; the clamp body assembly comprises a left clamping plate and a right clamping plate which are hinged together; a left nylon block and a right nylon block are arranged at clamping pins on the upper ends of the left clamping plate and the right clamping plate correspondingly; the support assembly is a threaded rod; a hinged through hole is formed in the upper end of the threaded rod; an adjusting nut is connected to the threaded rod ina threaded mode; the lower end of the right clamping plate is hinged to the adjusting nut through a second hinged bolt; and the middle part of the left clamping plate is hinged to the hinged through hole through a third hinged bolt. According to the tool, with the cooperation of the adjustment by an operator for butt joint, equipment can be stably closed, the size is small, the operation is simpleand flexible, and carrying is convenient; a tool body frame is designed into a clamping structure, the clamping pins are inserted into corresponding bolt holes of two flange plates, and the two flange plates are connected in a butt joint mode by tightening a clamp; and in the using process, no damage is caused to an equipment shell, a bus cylinder and the flange plates.

Description

technical field [0001] The invention relates to the technical field of GIS equipment installation, in particular to a special connection tool for GIS. Background technique [0002] The statements herein merely provide background information related to the present application and may not necessarily constitute prior art. [0003] GIS is the English abbreviation of Gas Insulated Totally Enclosed Combined Electrical Appliance. GIS is composed of circuit breaker, isolating switch, grounding switch, transformer, lightning arrester, bus bar, connector and outlet terminal, etc. These devices or components are all enclosed in a metal grounding shell, and the inside is filled with a certain pressure of SF6 insulating gas , so it is also called SF6 fully enclosed combined electrical appliance. [0004] GIS switchgear is widely used because of its compact structure, small footprint and high reliability. When installing GIS switchgear, the equipment docking process is essential. Amo...

Problems solved by technology

[0005] In the existing installation operation of combined electrical equipment, the connection of GIS busbars depends on cranes outdoors, and tripods or manpower indoors. The stability, balance, and accuracy of the connection process cannot be controlled, resulting in excessive stress on the pot insulators, which can easily lead to damage. ;The levelness and verticality of the GIS main busbar are only measured by the level ruler and the line pendant. The overall deviation of the busbar is large, and the conductive bar of the main busbar deviates from the center of the contact finger. It is easy to generate heat and cause equipment failure; when connecting pot insulators, the insertion depth of the contacts depends entirely on the experience of the installer, and cannot be measured accurately; When the conductor and the plum blossom contact are inserted, the resistance to the docking process of the GIS bus barrel is increased, and it must be pulled in with ropes by additional personnel. At least 6 people are required to complete the whole process

Not only is it difficult to control the stability of the equipment docking, but also a little carelessness will cause damage to the equipment shell, seriously affecting the efficiency of equipment installation
