Problems solved by technology

[0002] With the wide application of drawer-type low-voltage switchgear in power distribution systems, the drawer interlock mechanism commonly used is to control the work, test, isolation and withdrawal of the drawer unit by rotating the opening and closing handle. This drawer interlock mechanism The structure is complex, the cost is high, the drawer takes up a lot of space, and the operation is not flexible enough. At the same time, the indication points of the working, testing, isolating, and withdrawing positions are located on the arc surface of the opening and closing handle, and the action signs are not obvious, which is easy to cause misoperation.

Abstract

The invention discloses a hand pulling type propulsion mechanism which comprises the components of a switching on-and-off handle, a switch handle shaft, an interlocked base board, a propulsion interlocked hand pulling mechanism and a switching-on interlocking component. The propulsion interlocked hand pulling mechanism is fixed on the interlocked base board. The switch handle shaft is provided with the switching-on interlocking component. Through operating the switching on-and-off handle and a propulsion interlocked hand pulling mechanism connecting rod, unit drawers are separated, tested and connected. The hand pulling type propulsion mechanism has advantages of simple structure, convenient operation, high economic performance, high practicability and high universality. The hand pulling type propulsion mechanism is suitable for use in power distribution operation of an electrical department.

Description

technical field [0001] The invention belongs to the technical field of power distribution devices, and in particular relates to an operating mechanism on a drawer-type switchgear that enables the drawer to be pushed and pulled out accurately and reliably. Background technique [0002] With the wide application of drawer-type low-voltage switchgear in power distribution systems, the drawer interlock mechanism commonly used is to control the work, test, isolation and withdrawal of the drawer unit by rotating the opening and closing handle. This drawer interlock mechanism The structure is complex, the cost is high, the drawer takes up a lot of space, and the operation is not flexible enough. At the same time, the work, test, isolation, and withdrawal position indication points are located on the arc surface of the opening and closing handle, and the action signs are not obvious, which is easy to cause misoperation. Contents of the invention [0003] The purpose of the present...
