Verification method for three-phase synchronous debugging of high-voltage isolation switch

Abstract

The invention belongs to the technical field of high-voltage isolation switch installation engineering. The invention specifically discloses a verification method for three-phase synchronous debuggingof a high-voltage isolation switch. The method aims at the action characteristics of a high-voltage isolation switch with the voltage class of 110kV or above. By means of three-dimensional laser scanning techniques, automatic test and datamation analysis are carried out on closing action time, closing action synchronism and closing action smoothness of three-phase opening and closing, an existingoriginal method depending on manual measurement is replaced by equipment data testing and analysis, automation and intelligence of debugging and checking of the high-voltage isolation switch are achieved, in the debugging and checking process, constructors do not need to stand on an isolation switch platform for auxiliary measurement, and the advantages of being accurate in data, easy to operateand high in safety are achieved.

Description

technical field [0001] The invention belongs to the technical field of high-voltage isolating switch installation engineering, and more specifically relates to a verification method for three-phase synchronous debugging of a high-voltage isolating switch. Background technique [0002] In the power system, the transmission path of electric energy is mainly composed of main equipment such as power lines, disconnectors, circuit breakers, and transformers. The main function of the isolating switch in the operation of the power grid is to isolate the power supply, and use the isolating switch to separate the equipment that needs to be overhauled from the equipment that is running live, so that there is an obvious disconnection point to ensure the personal safety of the maintenance personnel; change the operation mode of the power grid , It can be used as a switching device for equipment and circuits for opening and closing operations with small operating currents.

Problems solved by technology

[0004] Due to the high-voltage isolating switch three-phase synchronization results require fine, repeated checks on this data are often required during the installation and acceptance process, but at present most of them rely on the construction personnel to measure on-site with the naked eye and a ruler, the method is backward, the efficiency is low and the data is not accurate enough

Moreover, during the on-site measurement, one person operates the isolating switch to open and close, and another person observes and measures on the high-altitude platform of the isolating switch. This situation poses a great risk to the personal safety of the construction workers and is likely to cause personal injury.
