Embodiment 1

[0018] Fig. 2 is a schematic diagram of the first structure of the present invention, showing the first embodiment of the present invention.

[0019] This embodiment is a reset mechanism for a frame-type circuit breaker, which includes a housing 1, a reset push rod 2, and a spring 3 for providing elastic force for the reset push rod 2 to reset itself; A first force-receiving part 21 is provided, and the housing 1 is also provided with an electric operating mechanism 4 for driving the reset push rod 2 to move through the first force-receiving part 21 . The electric operating mechanism 4 is an electromagnetic operating mechanism fixed on the housing 1 , and the electromagnetic operating mechanism includes a coil fixed on the housing 1 and a moving iron core 41 located in the coil. The reset push rod 2 is arranged under the electromagnetic actuating mechanism, and the first force-receiving part 21 is arranged on the top of the reset push rod 2 .

[0020] In this embodiment, by a...

Embodiment 2

[0022] Fig. 3 is a schematic diagram of the second structure of the present invention, showing the second embodiment of the present invention.

[0023] This embodiment is basically the same as Embodiment 1, except that the reset push rod 2 is longer, and its top protrudes out of the housing 1 to form a pressing handle 23 . The electric operating mechanism 4 is no longer located directly above the reset push rod 2, but on one side thereof, and the first force receiving member 21 of the reset push rod 2 is a blocking piece protruding laterally along the reset push rod 2 ; Such a structure makes the present embodiment can be electric remote operation, but also on-site manual operation.

Embodiment 3

[0025] Fig. 4 is a schematic diagram of the third structure of the present invention, showing the third embodiment of the present invention.

[0026] This embodiment is basically the same as Embodiment 2, except that: the reset push rod 2 is also provided with a laterally protruding second force-receiving part 22, and the reset mechanism also includes a fixed on the housing 1, and The photoelectric converter 5 that can be triggered by the second force-receiving part 22 .

[0027] In this embodiment, a second force-receiving part is arranged on the reset push rod, and after a photoelectric converter is added in the casing, when the reset push rod drives the external interlocking mechanism, the photoelectric converter is also triggered, thereby giving the corresponding The control circuit inputs an electrical signal, so that the intelligent controller of the core component can be reset from the fault tripping state, so that the closing can be carried out smoothly; in this way, t...

Abstract

The invention discloses a reset mechanism of a frame type circuit breaker, the reset mechanism includes a shell body, a reset push rod and a spring which is used for providing the elastic force for self-reset of the reset push rod; a first force receiving part is further arranged on the reset push rod, and an electric operating mechanism which is used for driving the reset push rod to move via the first force receiving part is also arranged in the shell body. The invention is provided with the frame type circuit breaker which can be operated by remote control.

Description

technical field [0001] The invention belongs to the technical field of structural design of circuit breakers, in particular to a reset mechanism of a frame type circuit breaker. Background technique [0002] When the frame circuit breaker has a tripping fault, in order to prevent it from being closed by mistake if the fault is not eliminated, a mechanical interlock mechanism and a reset mechanism to reset the interlock mechanism are usually set on the circuit breaker. [0003] Fig. 1 is a structural schematic diagram of a reset mechanism of a traditional frame-type circuit breaker, showing a reset mechanism of a traditional frame-type circuit breaker; the reset mechanism includes a housing (1), a reset push rod (2), and is used for The reset push rod (2) resets itself to provide a spring (3) with elastic force, and the spring (3) is arranged on the top of the reset push rod; when in use, manually press the reset push rod, the reset push rod moves downward, and the reset push...
