Description

technical field

[0001] The invention relates to the field of medium and low voltage switches, in particular to a rotary clutch. It can be adapted to spring operating mechanisms of various medium and low voltage load switches and circuit breakers, and is used as clutch and protection for operating force, spring energy storage, and closing action. Background technique

[0002] At present, in the spring operating mechanisms of various medium and low voltage load switches and circuit breakers at home and abroad, the clutch and protection of the operating force, spring energy storage, and closing action are all controlled in the form of friction lock; due to the friction lock form The friction of the locking point is very large and easy to wear, which has a relatively large negative impact on the reliability, stability, and durability of the clutch action. This friction locking form is now widely used in various types of spring operating mechanisms. The reliability of the action...
