Temperature-measuring outdoor high-voltage enclosed isolating switch with switching-on indication and assistance

Abstract

The invention relates to the technical field of power systems, in particular to a temperature-measuring outdoor high-voltage enclosed isolating switch with switching-on indication and assistance. The switch includes a base, insulators, an incoming line contact box, an outgoing line contact box and a movable contact knife, wherein one ends of the two insulators are symmetrically arranged at the two ends of the upper surface of the base, the lower ends of the incoming line contact box and the outgoing line contact box are fixed to the upper ends of the insulators respectively, and the movable contact knife is hinged to the outer side of the outgoing line contact box. When the movable contact knife is in a closed state, the movable contact knife is in close contact with static contacts arranged in the incoming line contact box and the outgoing line contact box, and wiring terminals are arranged on one side face of the incoming line contact box and one side face of the outgoing line contact box respectively. The invention aims to solve the problems that virtual closing and false closing are easy to occur when a disconnecting switch in the prior art is switched on to cause heating of a contact part, and the temperature of the contact part is difficult to measure, so that the maintenance difficulty of operation and maintenance personnel is increased.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to an outdoor high-voltage closed isolating switch with temperature measurement belt closing indication and power assistance. Background technique [0002] Outdoor high-voltage isolating switches are widely used on distribution lines for isolation or branching. For example, Patent No. CN201810954312.4 "A Power Safety Isolating Switch", which includes a main body of the isolating switch, a rotating mechanism, a handle, a driving mechanism, a connecting mechanism, and a control mechanism of the isolating switch; mechanism, the isolating switch control mechanism is used to control the on-off of the isolating switch; the isolating switch control mechanism is connected to the driving mechanism through the connecting mechanism, and the driving mechanism is used to drive the isolating switch control mechanism to rotate , the connecting mechanism is used to adjust the position of the...
