The Research On The Hydraulic Spring Mechanism Of 550KV GIS

The malfunction of the high voltage switchgear, especially all kinds of operation mechanism is not successful on its design and manufacture, bring great economic lose to the electric power system.It is a important task for which engaged in the new product designed to find a good method and designed a new product.The first, in this article analyzed the development of the hydraulic spring operating mechanism and based on the theory of energy and liquid, founded the athletics equation in the case of no load. So it was certainly to know the fluence of the data which come from the mechanism.This thesis gaved a detail account to the main part. For example: the design of the cylinder and the piston rod; the time calculate of the valve ; the design of the disc spring and how to use it.At last, the mechanism is measured on the simulate device and on the circuit breaker. The result show that the mechanism is reasonable on its structure design, it can be put in the market.With this paper's theory and the experience of the factory , the mechanism have passed the examination of the electric department. It encouraged us to make a great progress constantly through our study and get win in market competition.
