Abstract

The invention provides an in-place monitoring method for a knife switch of an isolation switch. The in-place monitoring method involves the following device for implementing the monitoring method. Thedevice comprises a base, a movable contact and a static contact and also comprises the knife switch and a positioning sliding way, wherein the movable contact and the static contact are arranged on the base, the positioning sliding way is fixed on the base, one end of the knife switch is hinged with the movable contact, an insulation positioning plate is fixedly arranged at the other end of the knife switch, an operating ring is arranged at an outer side of the insulation positioning plate, guide rods are respectively hinged with two sides of the insulation positioning plate, the positioningsliding way is perpendicular to the static contact and is arranged at an outer side of the static contact, a positioning groove is formed in a middle part of the positioning sliding way and is corresponding to the insulation positioning plate, the bottoms of the guide rods are arranged in the positioning sliding way in a sliding way, and a fixed clamping buckle is arranged on the base and is corresponding to the operating ring. The in-place monitoring method for the knife switch of the isolation switch has the advantages of scientific design, high practicability, good closing effect and long service lifetime of the knife switch and is convenient to operate.

Description

technical field [0001] The invention relates to a method for monitoring opening and closing of an isolating switch, in particular to a method for monitoring the position of a knife switch of an isolating switch. Background technique [0002] As an important component of the transmission line, the isolating switch is mainly used to cooperate with the circuit breaker and other on-off transmission lines, so that the transmission line has an obvious disconnection point, so as to ensure the safety of maintenance personnel and equipment. However, the existing isolating switch is composed of dynamic and static contacts and a knife switch. With the increase of the number of opening and closing, the coordination error between the static contact and the knife switch is increasing, and the closing effect is poor, and even cannot be closed normally. Cause the isolating switch to not work properly. The replacement of the isolating switch is complicated and the construction is inconvenie...
