Problems solved by technology

[0002] At present, during the use of high-voltage circuit breakers, due to the different types of cabinets and cost considerations, manufacturers often choose some fixed high-voltage circuit breakers. This type of circuit breaker is fixed in the cabinet and does not need to be moved, so the chassis is removed. car, resulting in the lack of five-proof interlocking, which may easily lead to misoperation by the operator and cause property damage or even personal injury.

Embodiment Construction

[0022] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0023] The invention provides such a circuit breaker, which has an interlocking device, which can be used on the circuit breaker to connect it with the matching cabinet to play the role of five-proof interlocking. The circuit breaker, such as figure 1 As shown, it includes a circuit breaker frame 21, one side of the circuit breaker frame 21 is connected to a rotatable rotating shaft 5, and one end of the rotating shaft 5 is connected to the switch cabinet through the connecting piece 1, and the rotating shaft 5 drives the opening shaft 24 to rotate through the pressure rod 7, and the opening shaft 24 rotation reversely pushes the connected holding shaft 16 to rotate, so that the holding shaft 16 and the holding detent 17 are tripped to realize opening, as Figure 4 Shown in; The circuit br...

Abstract

The invention discloses a novel circuit breaker. The novel circuit breaker comprises a circuit breaker framework (21); a rotatable rotary shaft (5) is connected with one side of the circuit breaker framework (21); one end of the rotary shaft (5) is connected with a switch cabinet through a connecting sheet (1); the rotary shaft (5) drives a brake-separating shaft (24) to turn through a compression bar (7) to inversely push a connected retaining shaft (16) to turn and to de-buckle a retaining latch (17) so as to realize brake separating; the circuit breaker is further provided with an energy storage apparatus; when the retaining shaft (16) and the retaining latch (17) turn in a buckled manner, the energy storage apparatus is driven to store energy. The novel circuit breaker can ensure that the circuit breaker is in a switch-off state in overhauling by a working staff so as to ensure the personnel security.

Description

technical field [0001] The invention relates to a switchgear, in particular to a circuit breaker with an interlocking device. Background technique [0002] At present, during the use of high-voltage circuit breakers, due to the different types of cabinets and cost considerations, manufacturers often choose some fixed high-voltage circuit breakers. This type of circuit breaker is fixed in the cabinet and does not need to be moved, so the chassis is removed. The car, resulting in the lack of five-proof interlocking, may easily lead to misoperation by the operator and cause property damage or even personal injury or death. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and provide a circuit breaker that can ensure that the circuit breaker is in the disconnected state when the staff inspects and repairs, so as to ensure the safety of personnel. [0004] In order to achieve the above object, the techn...
