The utility model provides an arc extinction device used for live working. The device comprises a cable clamp fixture, the lower portion of the cable clamp fixture is provided with a vacuum arc extinction switch tube, the upper end of the vacuum arc extinction switch tube is fixedly connected with the cable clamp fixture, the lower end of the vacuum arc extinction switch tube is connected with a pull rod through a connection head, the outer portions of the vacuum arc extinction switch tube and the connection head are sleeved with an insulation sleeve, the outer portion of the pull rod is sleeved with an insulation rod, the side wall of the insulation rod is provided with a spacing switch device, the bottom portion of the pull rod is provided with a handle, the outer wall of the insulationsleeve is provided with a rotation rod, the rotation rod is provided with an insulation elastic clamp and a metal clamp, the lower portion of the vacuum arc extinction switch tube is connected with the metal clamp through a bypass wire, and a branch drainage wire is fixed on the rotation rod through the insulation elastic clamp and the metal clamp. The 'one-rod multi-purpose' mode provided by theinvention optimizes the operation flow, the main wire and the branch drainage wire are independently fixed and installed to improve the operation comfort; and moreover, the rotation rod is employed toachieve that the branch drainage wire is fixed in the groove so as to achieve the integration function of the arc extinction tool, and the insulation design ensures the safety performance.
Description
technical field [0001] The invention relates to a safety protection tool for live work on distribution network lines, in particular to an arc suppression device for live work. Background technique [0002] With the rapid development of the market economy, the reliability of power supply is required to be higher and higher. The development of enterprises is inseparable from the reliable guarantee of power. The original power outage maintenance and power outage transformer capacity expansion are no longer suitable and have seriously affected the reliability of enterprise production and power consumption. As a novel non-stop maintenance method, live work solves the contradiction between power and user needs. More and more attention has been paid to non-stop maintenance, and it has gradually formed a trend. Due to the importance of insulating tools and hardware equipment in the process of live work, it determines the efficiency and safety of live work. As a highly professional ...
