HGIS self-adaption emergency first-aid repair device and applications thereof

Abstract

An HGIS self-adaption emergency first-aid repair device and applications thereof belong to the field of first-aid repair device. The emergency first-aid repair device is assembled on site through the following steps: a cantilever hanging base plate is arranged on a fork of a fork truck, the cantilever hanging base plate is provided with a cantilever hanging unit, a butt-joint crossbeam is arranged on the tail end of a cantilever crossbeam, a bearing pillar is arranged on the tail end of the butt-joint crossbeam, a bearing base is arranged on the lower part of the bearing pillar, the tail end of the butt-joint crossbeam and the top part of the bearing pillar are in a pin connection or hinge connection, and the cantilever hanging base plate, the cantilever hanging unit, the butt-joint crossbeam, the bearing pillar and the bearing base are all self-contained. When performing the first-aid repairing, the connections between group/part elements are in a fastener connection mode, and rapid assembly on the first-aid repair site is realized. After the first-aid repairing is finished, group/part elements can be rapidly decomposed, which is convenient for transportation, storage and maintenance separately. The whole emergency first-aid repair device adopts modular construction, and improves the work efficiency of examination, repairing and maintenance on site.

Description

technical field [0001] The invention belongs to the field of emergency repair devices, in particular to a portable hoisting system for compact combined high-voltage switchgear. Background technique [0002] High-voltage switchgear is generally divided into air-insulated switchgear (AIS), gas-insulated metal-enclosed switchgear (GIS, Gas Insulated Substation). In the late 1990s, a compact combined high-voltage switchgear (HGIS) appeared in the world. This device combines the advantages of open and closed switchgear, and the high-voltage components are highly integrated, making the high-voltage switchgear more compact. [0003] Compared with open switchgear, HGIS (Hybrid Gas Insulated Switchgear, mixed gas insulated switch) integrates circuit breaker, isolation / grounding switch, CT (current transformer), PT (voltage transformer), lightning arrester, etc. into one module, It greatly saves the floor area and improves the reliability of the equipment; compared with GIS equipmen...

AI Technical Summary

Problems solved by technology

[0007] The traditional construction of scaffolding is time-consuming and laborious, with long working hours and low maintenance efficiency. After the maintenance is completed, it still needs to be disassembled, which often results in too long interval power outages. In some interval circuits, the aisle is narrow. There is no place to park the crane, and the hoisting operation is difficult. It is difficult to park a large crane or the boom of the crane cannot be extended, and it is easy to touch the overhead line with a small charging distance, etc. It is impossible to quickly unload and repair the faulty equipment.

[0008] In actual work, in order to reduce the power outage time at the interval where the equipment is located, the maintenance and replacement time of the faulty component must be as short as possible, so the lifting and unloading process of the faulty component must be as fast and simple as possible. The distance is short, there is no place for large cranes to park, and the hoisting operation is difficult. There is an urgent need for a hoisting device to hoist and replace HGIS faulty parts (porcelain sleeves, current transformers, CB, mechanisms, etc.) to facilitate repair and maintenance. The hoisting device must be able to adapt to the narrow working environment of the existing substation, and at the same time meet the requirements of detachability and assembly, so as to facilitate the transportation of the parts of the device to the destination or return to the station by a small truck
