Problems solved by technology

[0003] The traditional electric opening and closing miniature circuit breakers have the defects of complex structure, easy failure and incomplete functions, which cannot meet the needs of power companies. Key points and difficulties of technicians' work
[0004] In addition, in the traditional electric opening and closing small circuit breakers, the Hall sensor is commonly used to realize the position sensing, but the Hall sensor has the following disadvantages: the induction accuracy is low, and the electromagnetic interference to the circuit board is relatively large due to its magnetism

Abstract

The invention discloses an automatic opening and closing drive device and a used linkage turbine thereof. The drive device comprises a shell, a drive motor, a linkage turbine, a linkage gear, an output main shaft, a release linkage part and a circuit board, wherein the drive motor is provided with a drive turbine; the drive motor drives the linkage turbine to rotate in a reciprocating manner through the drive turbine; the linkage turbine drives the release linkage part to rotate in the reciprocating manner through a cam linkage part and drives an external opening linkage release lever to carry out fast opening action through a driving lever part of the release linkage part; and the linkage turbine drives the linkage gear and the output main shaft to carry out automatic closing action through drive teeth of the linkage turbine. The linkage turbine is sequentially provided with a turbine driven part, a gear drive part and a cam linkage part along the axis direction of a rotation center; a plurality of drive teeth are arranged on partial peripheral wall of the gear drive part; and a driving boss is arranged at one side end, far away from the cam linkage part, of the turbine driven part. The automatic opening and closing drive device can achieve electric opening and closing and effectively reduces electromagnetic interference.

Description

technical field [0001] The technical field of the miniature circuit breaker of the present invention, in particular relates to an automatic opening and closing drive device and a linkage turbine used therein. Background technique [0002] According to the needs of my country's power supply network intelligence, the State Grid Corporation of China requires the power supply network intelligence. Therefore, it is necessary for the terminal actuator of the power supply network - the miniature circuit breaker (or miniature circuit breaker) to execute the upper-end signal and have the functions of tripping and closing. Therefore, the current development trend of miniature circuit breakers is that in addition to the traditional manual opening and closing and overcurrent and overload automatic tripping functions, it also needs to have an electric opening and closing function (commonly known as automatic opening and closing function) to achieve remote control; especially It is a com...
