Problems solved by technology

However, at present, it is still necessary to send personnel to the site to monitor and measure the various states and performances of the isolating switch. Substations with a relatively high level of automation usually use video monitoring as an auxiliary means to judge the opening and closing status of the isolating switch, but video monitoring exists only It is effective for some parts not in place / over position, but it is also easily affected by subjective human factors, angles, clarity, dirt and weather

Embodiment 1

[0021] figure 1 It is a flow chart of the attitude monitoring method of the disconnector of the present invention.

[0022] In this example, if figure 1 As shown, the present embodiment provides a disconnector posture monitoring method, which includes: collecting the disconnector posture, and performing calculation; outputting the opening and closing angle and action time of the disconnecting switch to judge the disconnecting state of the disconnecting switch; Calibrate the isolator when it experiences a static drift.

[0023] In this embodiment, after collecting the current attitude of the isolating switch in real time, this embodiment judges the opening and closing state of the isolating switch, and automatically calibrates the isolating switch, which can well overcome the difficulty of traditional attitude sensors in judging the opening and closing of the isolating switch. The static drift and dynamic cumulative error in the state provide accurate judgment basis for reali...

Abstract

The invention relates to an isolating switch attitude monitoring method, which comprises the following steps: acquiring an attitude of an isolating switch, and performing calculation; outputting the on-off angle and the action time of the isolating switch so as to judge the on-off state of the isolating switch; and calibrating the isolating switch when the isolating switch generates static drift.According to the invention, after the current attitude of the isolating switch is collected in real time, the on-off state of the isolating switch is judged, and the isolating switch is automaticallycalibrated. Static drift and dynamic accumulated error generated when a traditional attitude sensor judges the on-off state of an isolating switch can be well overcome, and an accurate judgment basisis provided for the realization of intellectualization of a power grid.

Description

technical field [0001] The invention relates to the field of automatic monitoring of an isolating switch, in particular to a method for monitoring the attitude of an isolating switch. Background technique [0002] With the upgrading of the power grid and the promotion of substation automation technology, there are more and more unattended substations. At present, the success rate of one-time closing of the isolating switch cannot reach 100%, and whether the closing of the isolating switch is successful directly affects The normal operation of the power grid system is even related to the personal safety of the operator, so it is necessary to confirm the closing status of the isolating switch to avoid operating accidents caused by insufficient closing. . The isolating switch is very important and has the largest number of primary equipment in the substation. Therefore, it is very important to monitor the status of the isolating switch contacts and accurately judge whether the...
