Spring operating mechanism and closing lock latch system thereof

Abstract

The invention provides a spring operating mechanism and a closing lock latch system thereof. The closing lock latch system comprises a closing lock latch, wherein the closing lock latch is provided with a stopping end for stopping an energy storage stone roller and a limiting end for limiting a closing electromagnet. The closing lock latch is provided with a first working position at which the stopping end stops the energy storage stone roller and a second working position at which the closing electromagnet is not limited. The closing lock latch system further comprises an anti-idle-closing piece. The anti-idle-closing piece is provided with an anti-idle-closing working position which is matched with the closing lock latch in a stopping manner to avoid secondary closing when the closing lock latch is located at the first working position, and the anti-idle-closing piece is provided with an avoidance working position rotating away from the closing lock latch. Space can be provided for the closing lock latch to rotate in the unlocking direction when the anti-idle-closing piece is located at the avoidance working position, and the anti-idle-closing piece forms a limiting piece for limiting the rotating limit of the closing lock latch in the unlocking direction. The effects are that the anti-idle-closing piece is linked with an output shaft and does not depend on easily faulty components such as a reset spring, and the performance is more stable. In addition, the anti-idle-closing piece is fully utilized, other stopping structures do not need to be arranged, and the number of parts can be reduced.

Description

technical field [0001] The invention relates to a spring operating mechanism and a closing latch system thereof. Background technique [0002] The operating mechanism is an important equipment in the field of high-voltage power transmission and transformation, and is an important part of the high-voltage circuit breaker. The opening and closing operations of the high-voltage circuit breaker are realized through the operating mechanism. At present, the spring operating mechanism has been widely used in 252kV power grid equipment, but due to the short development time of the spring operating mechanism, the technology is not yet complete, and there are still certain technical difficulties in manufacturing a spring operating mechanism with stable and reliable performance. The closing latch system is the main component to ensure the stability of the opening and closing characteristics of the spring operating mechanism, which is directly related to the stability of the spring oper...

AI Technical Summary

Problems solved by technology

[0007] Although the above-mentioned closing latch system is provided with an air-proof closing structure, the air-proof closing member is also a component that pushes the closing latch to unlock. Manufacture and installation are relatively difficult, and the cooperation of the anti-aircraft return spring is required. Once the spring fails or fails, the anti-aircraft function of the mechanism will no longer be realized.
