Embodiment 1

[0032] An emergency closing and opening mechanism of a mine circuit breaker, comprising a hollow housing 1, a handle mounting part is formed on the lower part of the side wall of the housing 1 in an arc-shaped protrusion, and a handle opening is opened in the middle of the handle mounting part 4. A handle 3 is inserted into the handle opening 4, and one end of the handle 3 located in the housing 1 is rotated and mounted on the inner wall of the handle installation part through the handle shaft 301, and a partition 5 is fixedly installed in the inner cavity of the housing 1, and The partition 5 divides the housing 1 into an insurance chamber located on the front side and an installation chamber located on the rear side;

[0033] The installation cavity is provided with a closing and opening assembly and a closing and opening drive assembly for driving the closing and opening assembly for emergency closing and opening;

[0034] The closing and opening assembly includes an arc-sh...

Embodiment 2

[0042] The difference between this embodiment and embodiment 1 is that, as figure 1 with 2 As shown, the side of the housing 1 corresponding to the position of the handle 3 is embedded with a status display screen 2 for displaying the connection and disconnection status of the circuit, and is used for judging the status of the mine circuit breaker.

[0043] Refer to Example 1 for other undescribed structures.

Abstract

The invention relates to the technical field of electric power safety equipment, provides a mining circuit breaker emergency switching-on and switching-off mechanism, and aims to solve problems that an existing circuit breaker trips in a short circuit, however, in a high-dust environment such as a mine field and the like, an electric power worker needs to find the circuit breaker in a dark mine tunnel for resetting and switching-on in tripping, and the use is very inconvenient. The mechanism comprises a hollow shell, the lower portion of the side wall of one side of the shell protrudes in an arc shape to form a handle installation part, a handle opening is formed in the middle of the handle installation part, a handle is inserted into the handle opening, and the end, located in the shell, of the handle is rotatably installed on the inner wall of the handle installation part through a handle rotating shaft; and a partition plate is fixedly installed in an inner cavity of the shell and divides the shell into a safety cavity located on the front side and an installation cavity located on the rear side. The mechanism is especially suitable for emergency automatic switching-on and switching-off of the mining circuit breaker, and has a high social use value and an application prospect.

Description

technical field [0001] The invention relates to the technical field of electric power safety equipment, in particular to an emergency closing and opening mechanism of a mine circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break the current under normal circuit conditions and can close, carry and break the current under abnormal circuit conditions within a specified time. The frame circuit breaker is a mechanical switch type circuit breaker. The device can effectively cut off and connect the load circuit, and cut off the fault circuit to prevent the expansion of the accident and ensure safe operation. [0003] The existing circuit breaker will trip when there is a short circuit, but in a high dust environment such as a mine, the trip requires electricians to find the circuit breaker in the dark mine tunnel to reset and close, which is very inconvenient to use, and the trip caused by circuit fluctuations ...
