Description

technical field

[0001] The invention relates to a high-voltage electrical isolation switch installation tool, in particular to a high-voltage electrical isolation switch contact finger installation tool. Background technique

[0002] High-voltage isolating switches are the most widely used electrical equipment in power systems. Existing high-voltage isolating switches generally use finger-shaped contacts (contact fingers), such as GW4, GW5, GW14, GW25 and other isolating switches. Among them, there is a structure of a high-voltage isolating switch including a contact finger holder, a contact finger and a tension spring. The contact fingers are distributed on both sides of the contact finger holder, and the contact fingers located on both sides of the contact finger holder are tensioned by the tension spring arranged in the middle of the contact finger holder; the two ends of the tension spring respectively have an end hole, and the end hole is inserted with a The shaft pin ...

Examples

Embodiment 1

[0030] Embodiment 1: A contact finger installation tool for a high-voltage isolating switch, including a main body 1 and a hand pressing handle 2. The main body 1 includes a mounting part 11 and a fixed handle 12 extending from the rear end of the mounting part 11. The hand pressing handle 2 is axially connected to the At the rear end of the installation part 11, the hand pressure handle 2 is located above the fixed handle 12,

[0031] The lower part of the mounting part 11 is provided with a transverse channel 3, and the transverse channel 3 is provided with a connecting rod 4. The front end of the connecting rod 4 is provided with a hook 41, and the hook 41 stretches out from the front end of the mounting part 11. The rear end of the connecting rod 4 passes through the inclined The rod 5 is connected with the hand pressure handle 2, one end of the oblique rod 5 is axially connected to the hand pressure handle 2 through the first connecting shaft 6, the other end of the obliqu...

Embodiment 2

[0041] Embodiment 2: The other parts are the same as Embodiment 1, the difference is that the connecting rod 4 is connected with an adapter rod 30 , and the inclined rod 5 is axially connected with the transfer rod 30 .
