Abstract

The invention discloses a single-column double-arm vertical telescopic isolating switch closing and opening in-place detection method, which comprises the following steps: closing detection: S11) setting a closing pressure sensor in a busbar static contact rod of an isolating switch; and S12) making the closing pressure sensor collect the closing pressure of the busbar static contact rod, whereinif the closing pressure exceeds a preset closing pressure threshold value, the closing is in place; and opening detection: S21) arranging an opening pressing plate device on the conductive base limiting mounting plate of the isolating switch, and arranging an opening pressure sensor in the opening pressing plate device; and S22) making the opening pressure sensor collect the opening pressure of the crank arm extruding the opening pressing plate device of the isolating switch, wherein if the opening pressure exceeds a preset opening pressure threshold value, the opening in-place signal is achieved. According to the embodiment of the invention, the pressure sensor is directly arranged on the busbar static contact rod, so that the closing pressure is directly acquired. Direct collection of the opening pressure in the opening process is achieved through the opening pressing plate device and the opening pressure sensor.

Description

technical field [0001] The invention belongs to the field of electrical equipment state monitoring, in particular to a method and a device for detecting the opening and closing position of a single-column double-arm vertical telescopic isolation switch. Background technique [0002] As one of the important components of the power transmission and transformation system, the high-voltage isolating switch is the most used primary equipment in the power grid. The isolating switch must be closed in place to ensure that the contacts and fingers are in good contact. To ensure the safety of maintenance personnel, therefore, by adding intelligent components to the isolation switch body, the purpose of real-time monitoring of the opening and closing of the switch body in the maintenance operation is achieved, which can improve the operation efficiency of the power grid, reduce the workload of personnel inspection, and improve the operation accuracy. It plays an important role in reali...
