The invention relates to a plum blossom contact finger mounting method. The method comprises the of 1, inserting one end of each contact finger into an annular groove of a mounting seat, 2, sleeving aspring from a conical section at the end, which is back to the annular groove, of the mounting seat, pushing the spring to move along the conical surface from the end, which is back to the annular groove, of the mounting seat in the axial direction of the annular groove, and enabling the spring to slide off from the end, which is provided with the annular groove, of the mounting seat and enter two rear spring mounting grooves of the contact finger; 3, inserting the end, which is back to the mounting seat, of the contact finger into a static contact seat, and retreating the mounting seat to expose the first end part spring mounting groove; and 4, repeating the second step to mount the spring in the first spring mounting groove in a sleeving mode. According to the above steps, the problemsof difficult operation and low mounting efficiency caused by a large number of contact fingers when the contact fingers are mounted on an existing plum blossom contact switch device are solved.
Description
technical field [0001] The invention relates to a method for installing plum-blossom contact fingers. Background technique [0002] The electrical connection in the high-voltage switchgear is generally realized by the connection method of the plum blossom contact, and the plum blossom contact includes a moving contact part and a contact holding part. The contact holding part includes a static side contact finger group and a spring group. The moving contact part can be pulled out and inserted into the hole of the contact finger group on the static side according to the requirements to realize the opening and closing operation. In the closed state, the contact finger group on the static side and the moving contact part must be tightly hugged and have a certain degree of holding force, so as to ensure the reliable flow capacity between the moving contact part and the contact finger group on the static side, otherwise , The switchgear will cause serious heat generation due to ...
