Description

Technical Field

[0001] The utility model belongs to the technical field of electric power engineering equipment manufacturing, and in particular relates to a tooling for tensile testing of insulating swinging parts of disconnecting switches. Background Art

[0002] Gas insulated ring main unit is widely used in industrial and civil cable ring network and distribution network terminal projects for receiving and distributing electric energy. It is particularly suitable for power distribution in urban residential areas, small secondary substations, cable branch boxes, box-type substations and other places. At present, the commonly used gas insulated ring main unit on the market mostly adopts a structure combining a three-position isolating switch and a circuit breaker. Common three-position switches are mostly composed of a frame made of metal plates, isolating and grounding contacts, swinging three-phase moving contacts and insulating swinging parts covering the outside of the moving contacts. The movement of the three-phase moving contacts is completed by the operating mechanism driving the insulating swinging parts. When the ring main unit is in operation, the resistance of the three-position switch closing and opening operations and the electric force generated when the fault current passes through directly act on the insulating swinging parts. Therefore, the quality of the insulating swinging parts is directly related to the operating safety of the gas insulated ring main unit.

[0003] In the prior art, most common insulating swing parts are made of engineering plastic injection molding, and defects are inevitable during the production process. However, there is usually a lack of performance test and inspection of the insulating swing parts before the disconnector is assembled, which leads to poor safety. Therefore, a pressure testing machine can be used to perform performance test and inspection on the insulating swing parts. During the inspection, a tooling for installing the insulating swing parts needs to be set up to ensure the smooth and effective conduct of the experiment. Utility Model Content
