Abstract

The utility model relates to an outdoor high-voltage isolating switch which comprises three-phase monopole isolating switches same in structure, wherein each of the monopole isolating switches comprises an inlet wire connecting base, an outlet wire connecting base, a contact finger conductive rod, a contact bar conductive rod and a base; the inlet wire connecting base and the outlet wire connecting base are respectively mounted on two insulating pillars; the contact finger conductive rod is fixed on the inlet wire connecting base; the contact bar conductive rod is fixed on the outlet wire connecting base; the contact finger conductive rod comprises a U-shaped self-powered contact finger; the rear end of the U-shaped self-powered contact finger is fixed on a contact finger base; and upper and lower long fixing pins are respectively arranged on upper and lower two sides of the U-shaped self-powered contact finger, pass through a contact finger spring and a contact finger pressing plate in turn and are fixed in a fixing sleeve. A clamping force of the contact finger is adjusted to the best state by adjusting the long fixing pins and compressing the contact finger spring, so that the minimum contact resistance of the contact finger and the contact bar is ensured, the current through capacity of the isolating switch is increased, no shunt exists between the external contact finger spring and a conductive circuit and the service life of the contact finger conductive rod is prolonged.

Description

A kind of outdoor high-voltage isolating switch

Technical field

The utility model relates to a kind of outdoor high-voltage isolating switch.

Background technology

For the queen post isolating switch, its contact fracture texture and the action when divide-shut brake cooperate the through-current capability that has determined isolating switch largely.Existing queen post isolating switch generally adopts internally installed pull-spring tension fingertip to contact with contact; This built-in spring lost efficacy easily, caused between contact and the fingertip gappedly, and contact resistance is big and conductive capability is poor; In addition, internally installed pull-spring in addition may be from the conducting wire branch part that flows away.

Summary of the invention

The purpose of the utility model is to overcome the defective of prior art, provides a kind of spring of the contact of relying on oneself external, and the fingertip electric conductivity is strong, and the outdoor high-voltage isolating switch of durable more.

For realizing above-mentioned purpose, the utility model adopts a kind of like this outdoor high-voltage isolating switch, comprises that three-phase has the single-pole isolator of same structure; Described single-pole isolator comprises inlet wire junction block and the outlet junction block that is installed on respectively on the two insulated pillars, is fixed on the fingertip conducting rod on the described inlet wire junction block, is fixed on the excellent conducting rod that touches on the described outlet junction block; And base; Drive the operator vertical links by operating mechanism, make described two insulated pillars backward rotation simultaneously through connecting lever, gangbar, described fingertip conducting rod comprises the U-shaped fingertip of relying on oneself; The rely on oneself rear end of fingertip of described U-shaped is fixed on the fingertip seat; The rely on oneself both sides up and down of fingertip of described U-shaped are established respectively and are upper and lowerly fixedly had strong market potential, and pass fingertip spring, fingertip pressing plate successively, are fixed in the fixed cover.

Especially; Described touch excellent conducting rod comprise with described U-shaped rely on oneself connecting plate that fingertip contact is connected, conductive strips, be connected and be furnished with the conductive head of lining with described outlet junction block; And protective cover; Described connecting plate and described conductive head are fastened fixing by described conductive strips, described protective cover holds the part that is fixedly connected of described connecting plate and described conductive head.

Especially, be fixed in the left alternate arm-tie on the main shaft, draw right alternate arm-tie, the described gangbar between the adjacent phase is synchronized with the movement through the operator interphase connecting rod.

Compared with present technology; The beneficial effect of the utility model is embodied in: through adjusting the compression fingertip spring of fixedly having strong market potential; Make the chucking power adjustment optimal state of fingertip, can guarantee that promptly fingertip and the contact resistance that touches rod reach minimum, have improved the through-current capability of isolating switch; The fingertip spring of external can not shunted from the conducting wire simultaneously, has prolonged the useful life of fingertip conducting rod; In addition, the excellent conducting rod that touches with matching is set, wherein protective cover can prevent that rainwater, dust from dropping into the part that is fixedly connected of connecting plate and conductive head, has improved the electric conductivity that touches the rod part.The utility model product has simple in structure, and alternate arm-tie reliably links, the characteristics that conducting rod can rotate flexibly.
