Problems solved by technology

This fire-fighting type control and protection switch operating mechanism has the following disadvantages: (1) it cannot be manually controlled on the spot, that is, the on-off control of the main circuit cannot be realized through the control handle, and it can only be controlled by buttons on the spot or remotely. The use and maintenance of the product brings a lot of trouble
(2) The wiring lines are relatively cumbersome, which reduces the overall reliability of the product

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the embodiments and the drawings.

[0023] See Figure 1-Figure 4 , An operating mechanism for controlling and protecting switch electrical appliances, which includes a mounting plate 1 and a face shell 12. The face shell 12 is marked with automatic control position (Auto), trip position (Trip), breaking position (Off), and reset position (Reset), isolation position (O), the mounting plate 1 is equipped with a thermal-magnetic trip unit, a main circuit contact group, an electromagnetic transmission mechanism, and an isolation mechanism that can be connected with KB0 to control and protect the switching device. Push rod 8, and push plate in parallel 7. Rocker arm 9, pull rod 10, and manually operated indicating knob 11, which can be placed in automatic control position (Auto), trip position (Trip), breaking position (Off), reset position (Reset) ), isolation position (O), the mounting plate 1 is also e...

Description

1. Technical field [0001] The present invention belongs to the control and protection switching equipment in the field of low-voltage electrical appliances. More specifically, the present invention is an operating mechanism for KB0 control and protection switching equipment with fire-fighting function. 2. Background technology [0002] "Control and Protective Switching Device" (control protector) is a new product in low-voltage electrical appliances. As a new category of products, its product category code is "CPS", which is the abbreviation of "Control and Protective Switching Device" in English. The main feature of CPS is: to achieve integrated, internally coordinated control and protection functions on a single structure product, which can replace circuit breakers (fuse), contactors, overload (or overcurrent, open phase) protection relays , Starters, isolators and many other traditional separation components. KB0 is the first generation of CPS products. KB0...
