Description

A sliding type gantry crane with rollers and its application

technical field

The invention specifically relates to a sliding type gantry crane with rollers and its application, which belongs to the field of installation and maintenance of GIS equipment.

Background technique

In the power industry, GIS is the abbreviation of "Gas Insulated Switchgear" (Gas Insulated Switchgear), which refers to all equipment in a substation except transformers, including circuit breakers, disconnectors, grounding switches, voltage transformers, and current transformers. , surge arrester, busbar, cable terminal, inlet and outlet bushing, etc., are organically combined into a whole through optimized design, which is the switch station that we often see, also called high-voltage power distribution device.

GIS is high-voltage electrical equipment with high operational reliability, less maintenance workload, and long maintenance cycle. Its failure rate is only 20% to 40% of conventional equipment, but GIS also has its inherent shortcomings. Due to the leakage of SF6 gas and the external moisture Infiltration, the presence of conductive impurities, the aging of insulators and other factors may lead to internal flashover faults in GIS. The fully sealed structure of GIS makes it difficult to locate and repair faults, and the maintenance work is complicated. The average maintenance time after an accident is longer than that of conventional equipment, and its power failure range is large, often involving non-faulty components. Therefore, some hoisting equipment is often used to carry out hoisting operations during construction such as installation and maintenance of GIS.

The existing crane used for hoisting equipment consists of a main beam part, a control part and a supporting part. For the existing crane, if the fixed support moving track is used, permanent moving tracks must be installed on the walls on both sides. A GIS room must use one crane and cannot be used for other purposes. If the fixed support moving track is not used , it is not suitable for the work site of civil construction; the existing crane is strong and has good load-bearing capacity, but it cannot be disassembled and cannot be assembled and used in the GIS room of the substation; the existing crane is too large to be suitable for the narrow space in the substation; the existing The weight of the vehicle is too heavy to be easily transported to the indoor site of the substation GIS.
