Description

Technical Field

[0001] The present application relates to the technical field of switch technology, and particularly relates to a closing spring assembly device for a disconnector. Background Art

[0002] With the rapid development of the machinery manufacturing industry, there are increasing requirements for reducing the level of manual operation, simplifying the operation process, and reducing manual physical consumption. The assembly tooling for assembly workers has become increasingly important.

[0003] A high-voltage disconnector is a switching device that has a specified insulation distance between contacts and an obvious disconnection mark in the open position; and can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time in the closed position.

[0004] Currently, for the assembly of the finger contacts of GW4D and GW5D disconnectors, generally, manual loading of the closing compression spring for the finger contacts is adopted. And due to the simple assembly process, it is generally a pure manual assembly. The closing spring is forcefully compressed and pressed into the finger contact. It is very difficult to ensure that the spring is accurately pressed into the finger contact, and it is also difficult to ensure that each assembly can be successful at one time. Moreover, there are safety risks of finger injury and quality problems of scratching the coating of the finger contact.

[0005] The existing situation of the finger contact spring is pure manual assembly. Although the assembly process is relatively simple, but using pure manual assembly, not only does it require assembly workers to consume more physical strength, at the same time, because each assembly depends on manual compression of the spring into the finger contact, it is also difficult to ensure that each assembly can be successful at one time, and there are often situations of finger injury and scratching, with relatively large safety risks. Affected by various factors, the assembly efficiency is greatly reduced, which greatly affects the production efficiency.
