Contact-finger installing tool for high-voltage isolating switch

Abstract

The invention discloses a contact-finger installing tool for a high-voltage isolating switch, wherein a transverse passage is arranged in the lower part of an installing part, a connecting rod is arranged in the transverse passage, a hook is arranged at the front end of the connecting rod, the hook extends out of the front end of the installing part, the rear end of the connecting rod is connected with a hand-pressing handle through an inclined rod, a shaft-pin passage which is vertical to the transverse passage is arranged at the front end of the installing part, a pin outlet is arranged at the lower part at the front end of the installing part, the pin outlet is communicated with the shaft-pin passage, the pin outlet is communicated with the transverse passage, an open slot which can beused for containing the end part of a contact-finger stretched spring is arranged at the front end at the lower part of the installing part, the upper end of the installing part is in shaft connection with a pressure plate, a second reset spring is arranged between the pressure plate and the installing part, a column body for downwards pushing and pressing a shaft pin is arranged at the front endof the pressure plate, and a pushing and pressing mechanism is arranged between the pressure plate and the hand-pressing handle. The invention has the advantages that when the installing tool is operated, the hand-pressing handle only needs to be pressed to pull out the contact-finger stretched spring, meanwhile, the shaft pin is nailed into the end hole of the contact-finger stretched spring, and the installing tool is quite convenient to operate.

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 ...

AI Technical Summary

Problems solved by technology

There are no relevant tools in this assembly process, and the pulling operation is done directly by hand, which is likely to cause injuries to electric workers during the operation, so the safety is not enough

At the same time, manual operation leads to relatively low work efficiency, and it is easier to damage the conductive coating on the surface of the contact finger, reducing the service life of the contact finger
