Embodiment Construction

[0071] The double locking mechanism (M) in the prior art has been described above, and the description will not be repeated.

[0072] For the sake of clarity, the common elements of the double locking mechanism (M) in the prior art and the double locking mechanism (Mi) of the present invention are denoted by the same reference numerals.

[0073] Considering the direction of component stacking, the mechanism (Mi) of the present invention includes the following main elements:

[0074] -The first rotating piece, called the actuation wheel 1, is fixed to a shaft 10 called the actuation shaft and is adapted to be rotated by a manual key 9. As explained above, this round also performs the function of disconnecting round 3 and includes the equipment system 2.

[0075] -Control shaft 12, fixed to the combined actuating, equipping and disconnecting wheels 1, 2, 3,

[0076] -The second rotating member, called the output and closing wheel 4, which includes a shaft called the output shaft 40, whic...

Abstract

The mechanism (Mi) has a closing spiral spring (6) and an open spiral spring (5) including interior ends that are fixed to a control shaft (12). An exterior end of the open spiral spring is fixed to a frame of the mechanism. An exterior end of the closing spiral spring is fixed to a closing wheel (4). A coupling unit is integrated with respect to thickness of opening, configuring and controlling wheels (3, 2, 1). The coupling unit realizes uncoupling between the opening, configuring and controlling wheels and a manual lever at the end of configuration.

Description

Technical field [0001] The invention relates to the field of control devices for high-voltage or medium-voltage switchgear having at least one circuit breaker. [0002] The switchgear involved in the present invention can have up to three circuit breakers with different functions: for example, a current circuit breaker, a bus circuit breaker and a grounding circuit breaker. [0003] More specifically, the present invention relates to a control device including a locking mechanism, and the disarning mechanism has the effect of causing at least one circuit breaker to perform a closing and opening cycle in the operation of the switchgear. [0004] The present invention aims to propose a new structure of the locking mechanism. Background technique [0005] The control device for a high-voltage or medium-voltage switchgear having at least one circuit breaker includes a mechanism of the type commonly referred to as a double locking mechanism. [0006] The double locking mechanism for the con...
