Problems solved by technology

[0002] The vacuum contactor module is used as the start-stop action actuator of the mine combination switch. It is usually fixed with the switch by bolts. There are multiple vacuum contactor modules installed in each mine combination switch. Since the vacuum contactor module is a vulnerable part, it needs to be replaced frequently , for each replacement, it is necessary to cut off the power of the relevant lines first, then remove the fixing bolts, and finally pull out the entire vacuum contactor module from the box assembly. This design is not only complicated in operation, long in replacement time, and inconvenient in disassembly and assembly, but also for vacuum contactors. The process of extracting the converter module from the box assembly is also quite difficult

Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be described completely and clearly below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.

[0038] Such as Figure 1 to Figure 8 As shown, the specific implementation of a quick-plug fixing mechanism for a vacuum contactor module is as follows:

[0039] Normal working status:

[0040] The strong electric contact at the rear of the vacuum contactor module 30 is inserted into the terminal seat on the contact backplane 11, and the insertion bearing 36 presses the insertion track 14, so that the weak electric contact assembly 20 is at a low position, and the weak electric contact 23 and the weak electric static The contact 35 contacts and is compressed by a small spring inside the weak electric contact 23 . The handle 33 and the horizontal plane...

Abstract

The invention discloses a fast plug-in installation mechanism and an installation method of a mine switch vacuum contactor module. The mechanism includes box components, weak electric contact components, vacuum contactor modules, springs, etc., wherein the box components include bases, boxes, contact back plates, insulating connecting plates, insertion tracks, etc., and weak electric contact components include weak Electric contacts, cages, pull-out rails, etc., vacuum contactor modules include vacuum contactors, cages, handles, position fixing forks, etc. In the present invention, the mechanism is operated by operating the handle of the mechanism, so that the vacuum contactor is powered off before being pulled out and powered on after being inserted, and the strong electric contact is pulled out from the terminal seat contacting the backboard, inserted and fixed. The reliability of the action is improved, the labor intensity is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of combined switches for underground coal mines, in particular to a quick-plug installation mechanism and installation method for a vacuum contactor module of a mine switch.
