Problems solved by technology

[0005] The purpose of the present invention is to provide a fully sealed spring operating mechanism for a ring network cabinet, which solves the problem that the force value of the energy storage spring is too large, the strength of the mechanism is too high, and the overall sealing cannot be performed; the force value of the energy storage spring is too large, increasing The impact on the operating mechanism leads to low mechanical life or in order to increase the strength, more stable structural support is required, which increases the cost problem; and the structure of the operating mechanism is complex. Once the important transmission parts are rusted, the characteristic parameters of the operating mechanism will be affected. Even the problem of rejection

Abstract

The invention provides a fully-enclosed spring operating mechanism for a ring main unit. The fully-enclosed spring operating mechanism comprises an energy storage member, a switch-on holding and switch-off member, a transmission mechanism member and a state display member which are disposed on a support sheet metal member. The energy storage member provides kinetic energy for the transmission mechanism member by means of manpower or a motor in order to achieve switch-off. The switch-on holding and switch-off member holes a switch-on state and achieves a switch-off operation. The state display member displays switch-on and switch-off states. Respective components are integrally enclosed. The mechanical strength requirement and the cost of the fully-enclosed spring operating mechanism for a ring main unit are reduced, and the operating mechanism is fully enclosed.

Description

technical field [0001] The invention belongs to the technical field of medium-voltage switch cabinets, in particular to a fully-sealed spring operating mechanism for a ring network cabinet for a circuit breaker. Background technique [0002] The circuit breaker is an important equipment of the medium voltage switchgear. The spring operating mechanism of the circuit breaker matches the force curve of the spring with the load characteristics of the vacuum switch to the greatest extent through the ingenious four-bar linkage mechanism and the cam mechanism, so that the circuit breaker It can open and close, carry short-circuit current and meet a series of characteristic parameters required for sufficient mechanical life. At the same time, it also needs to meet the specified operating force, operating specifications and anti-misoperation requirements. For example, the spring operating mechanism must have both manual and electric. There are three kinds of energy storage methods; t...
