A detection device and method for the position of an isolating switch after closing based on optical characteristics are disclosed. The detection device includes a fixed bracket. A left cursor laser lamp, a right cursor laser lamp and an intermediate adjustment laser lamp are arranged from left to right on the same plane of the fixed bracket. The tail ends of the left cursor laser lamp, the rightcursor laser lamp and the intermediate adjustment laser lamp are hinged to the fixed bracket. Locking elements are respectively installed at the other ends of the left cursor laser lamp, the right cursor laser lamp and the intermediate adjustment laser lamp. The locking elements are arranged in a sliding manner on first chutes of the fixed bracket. The detection device for the position of an isolating switch after closing based on optical characteristics provided by the invention is used to detect the position of a high-voltage isolating switch after closing so as to make compensation for theerror of artificial naked-eye observation.
Description
technical field [0001] The invention relates to a position detection device in the switching operation of a high-voltage isolation switch, which is used for position detection after the high-voltage isolation switch is closed, in particular to a detection device based on optical characteristics. Background technique [0002] The high-voltage isolation switch, also commonly known as the knife switch, plays the role of isolating voltage and switching off in the power system. Since the isolation switch does not have an arc extinguishing device, it can usually only switch and close small current circuits. For high-voltage isolating switches with voltage levels of 35kV and above, outdoor open layouts are usually used. At present, in power systems, isolating switches with voltage levels of 35kV-110kV are mainly switched on and off manually, while for open type isolating switches, When separating, a clearly visible disconnection point can be formed, which can ensure the safety of m...
