Embodiment 1

[0018] figure 2 It is a schematic diagram of the first structure of the present invention, and shows the first embodiment of the present invention.

[0019] This embodiment is a reset mechanism of a frame type circuit breaker. The reset mechanism includes a housing 1, a reset push rod 2, a spring 3 for providing elastic force for the reset push rod 2 itself; the reset push rod 2 is also A first force receiving portion 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 portion 21. The electric operating mechanism 4 is an electromagnetic action mechanism fixed on the housing 1, and the electromagnetic action 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 action mechanism, and the first force receiving portion 21 is arranged on the top of the reset push rod 2.

Embodiment 2

[0022] image 3 It 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 the first embodiment. The difference is that the reset push rod 2 is longer, and the top of the reset push rod 2 extends 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. The first force receiving member 21 of the reset push rod 2 is a baffle which protrudes laterally along the reset push rod 2. ; Such a structure allows this embodiment to be electrically operated remotely or manually on site.

Embodiment 3

[0025] Figure 4 It is a schematic diagram of the third structure of the present invention, and shows 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 portion 22, and the reset mechanism also includes a second force receiving portion 22 fixed on the housing 1 and The photoelectric converter 5 can be triggered by the second force receiving part 22.

[0027] In this embodiment, after the second force receiving part is provided on the reset push rod and the photoelectric converter is added to the housing, 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 electric signal, so that the core component intelligent controller can be reset from the fault trip state, so that the closing can be carried out...

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 a frame-type circuit breaker has a tripping fault, in order to prevent it from being closed by mistake when the fault is not eliminated, a mechanical interlocking mechanism and a resetting mechanism for resetting the interlocking mechanism are usually set on the circuit breaker. [0003] figure 1 It is a schematic structural diagram of the reset mechanism of a traditional frame type circuit breaker, showing the reset mechanism of the traditional frame type circuit breaker; the reset mechanism includes a housing (1), a reset push rod (2), and is used for resetting The lever (2) resets itself to provide a spring (3) with elastic force, the spring (3) is arranged on the upper part of the reset push rod; when in use, the reset push rod is manually pressed, the reset push rod m...
