Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 and fig. 2, the present invention provides an apparatus for preventing a filter grounding switch from being touched by an error. The anti-misoperation device for the grounding switch static contact of the combined filter comprises an insulating protective shell 1 and a locking mechanism 2 installed on the insulating protective shell 1, wherein the locking mechanism 2 comprises a bolt 21, a lock cylinder 22, a lock sleeve 23, a nut 24 and a bolt 25, the lock sleeve 23 is locked on the insulating protective shell 1 through the nut 24, one end of the lock sleeve 23 extends into the insulating protective shell 1, the other end of the lock sleeve 23 is fixed on the insulating protective shell 1, the lock cylinder 22 can be rotatably installed in the lock sleeve 23, the bolt 25 locks the bolt 21 at one end of the lock cylinder 22 arranged in the insulating protective shell 1, and a slot 10 used for inserting the grounding switch static contact A is formed in the insulating protective shell 1. As shown in fig. 3 and 4, after the grounding switch fixed contact a is inserted into the slot 10, the insulating protective shell 1 covers the grounding switch fixed contact a, and the lock cylinder 22 can drive the lock tongue 21 to rotate to lock the grounding switch fixed contact a, so that the grounding switch fixed contact anti-collision device combined with the filter can be installed on the grounding switch fixed contact a.
