Description
Technical field
The invention belongs to high-tension switch gear, specifically a kind of breaker in vacuum circuit breaker operating mechanism is grasped and passed
Motivation structure.
Background technology
Its moving contact is manipulated by operating mechanism to move along a straight line, realize that divide-shut brake is grasped in vacuum circuit breaker running
Make.The power of its energy-stored spring exports a linear motion by transmission mechanism, and in traditional structure, transmission mechanism is usually and connects
Linkage, its each transmission link positions and dimensions set unreasonable, cause transmission resistance to be carried out, it is necessary to set larger spring greatly
Energy storage simultaneously exports power, not only increases manufacturing cost, reduces Reliability of Microprocessor, also increases operation energy consumption.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of simple structure, manufacture and easy for installation, running resistance
Small, reliability breaker behaviour's transmission mechanism high.
Breaker operator transmission mechanism of the invention includes the base plate of fixed installation, is provided with base plate and is grasped with breaker
Make the output shaft of mechanism's output par, c connection, driving connecting lever is installed on output shaft；Connecting lever is driven to be cut with scissors with the front end of first connecting rod
Connect, the rear end of first connecting rod is hinged by the first pivot pin with the front end of second connecting rod, the first pivot pin is led through first on base plate
Groove, and can be in the spacing lower movable of the first guide groove；Second connecting rod rear end is provided with the second pivot pin, and the second pivot pin passes through base plate
On the second guide groove, and can be moved linearly along the second guide groove in the vertical direction；Second pivot pin connects the biography of moving contact of breaker
Dynamic pull bar, can directly drive moving contact point, feed motion；First guide groove extends along the longitudinal direction, its bearing of trend to
Front lower place inclines and has one 2 ° -4 ° of angle with horizontal direction；Second guide groove vertically extends.
First pivot pin is contacted by the first roller with the guide edge of the first guide groove.
Second pivot pin is contacted by the second roller with the guide edge of the second guide groove.
The driving connecting lever is connected by an elastic jacket with the output shaft.
The present invention can drive the second pivot pin to drive moving contact of breaker to move linearly by the driving connecting lever for rotating, while
The first guide groove set by particular orientation and the second guide groove are coordinated, and optimize transmission link, whole stroke resistance is subtracted significantly
It is small, Reliability of Microprocessor is improve, the requirement to spring force is also reduced, so as to manufacturing cost can be reduced.
