Problems solved by technology

Because most of the high-voltage isolation switches are outdoors, the operating conditions are harsh, and most of the components are basically exposed. Due to the long-term impact of the external environment and climate, the electrical contacts of the isolation switch are oxidized to varying degrees, and the contact surface turns black.
Frequent operation of the isolating switch, serious damage to the electrical contacts, corrosion, cracks, and peeling off of the coating, etc., resulting in excessive contact resistance and high temperature rise of the electrical contacts, affecting the working performance of the isolating switch, which in turn affects the reliability of the entire circuit Safe and stable operation of permanent power supply and power grid
[0003] However, in the actual use of the prior art, the switch knife is not firmly fixed, and maintenance personnel can easily touch the switch knife by mistake. detachment, thereby creating a hazard to maintenance personnel and appliances

Abstract

The invention discloses a novel high-low voltage isolation switch. The isolation switch comprises a supporting seat, the top of the supporting seat is fixedly connected with a left insulating supporting column and a right insulating supporting column. The top of the left insulating supporting column is fixedly connected with a left wiring contact. A left wiring contact is fixedly connected to thetop of the left insulating supporting column, a right wiring contact is fixedly connected to the top of the right insulating supporting column, a disconnecting link is movably arranged at the top of the left wiring contact and the top of the right wiring contact, insulating partition plates are fixedly connected to the inner wall of the disconnecting link, and a first guide pipe and a second guidepipe are fixedly connected between the two insulating partition plates. According to the invention, the disconnecting link is rotated, so that the disconnecting link drives a movable rod to rotate through the insulating partition plates, the first guide pipe and the second guide pipe; and the movable rod drives the clamping head to rotate, and the surface of the clamping block is clamped with theinner wall of the clamping groove, so that the disconnecting link can be prevented from rotating reversely by matching the clamping block with the clamping head and the clamping groove, and the disconnecting link is firmly arranged at the top of the left wiring contact and the top of the right wiring contact.

Description

Technical field [0001] The invention relates to the technical field of isolation switches, in particular to a new type of high and low voltage isolation switches. Background technique [0002] The high-voltage isolating switch is the key equipment in the power system. It mainly isolates the overhauled high-voltage bus, circuit breaker and other electrical equipment from the live high-voltage line, and switches the high-voltage line under no-load conditions according to the operation requirements of the power grid. Load current, etc., is one of the most widely used high-voltage switchgear in the power system. Because the high-voltage isolation switches are mostly outdoors and the operating conditions are harsh, most of the components are basically exposed, and they are affected by the external environment and climate for a long time. The electrical contacts of the isolation switches are oxidized to varying degrees and the surface of the contacts becomes black. The isolation switc...
