Problems solved by technology
[0002] The three-position isolating switch currently on the market uses ambient air or high-pressure sulfur hexafluoride gas in a closed metal box as the insulating medium, and its insulation strength is greatly affected by the quality of the ambient air and the pressure of sulfur hexafluoride gas. , if the humidity and pollution of the ambient atmosphere are large and the pressure of sulfur hexafluoride gas is low, electrical breakdown may occur, causing power grid accidents and causing major economic losses

The invention discloses a three-position isolation switch, which comprises a housing, a line room and an insulating room, wherein the line room and the insulating room are arranged in the housing; theline room is arranged at the top of the insulating room; a partition plate is arranged between the line room and the insulating room and arranged at the bottom end of the line room; an electrified coil is arranged in the line room; a first support post is arranged at one side of the top end of the insulating room; a connection plate is arranged at one side of the first support post; a second support post is arranged at one side of the bottom end of the connection plate; a contact column is arranged at one side of the second support post; and a connection element is arranged at one side of thecontact column. Through the arrangement of the insulating room, isolation of the influence of internal voltage on the outside is facilitated and the damage to a human body is prevented; and through the arrangement of the partition plate, isolation of the line room from the insulating room is facilitated and a closed environment is provided for the insulating room, thereby achieving the target ofthe three-position isolation switch.
Description
technical field [0001] The invention relates to the technical field of control switches, in particular to a three-position isolating switch. Background technique [0002] The three-position isolating switch currently on the market uses ambient air or high-pressure sulfur hexafluoride gas in a closed metal box as the insulating medium, and its insulation strength is greatly affected by the quality of the ambient air and the pressure of sulfur hexafluoride gas. , if the humidity and pollution of the ambient atmosphere are large and the pressure of sulfur hexafluoride gas is low, electrical breakdown may occur, causing power grid accidents and causing major economic losses. Therefore, it is necessary to invent a three-position isolating switch to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a three-position isolating switch to solve the problems raised in the above-mentioned background technology. [0004] I...
