Isolated switch device based on automatic opening and closing function

Abstract

The invention discloses an isolated switch device based on an automatic opening and closing function. The isolated switch device comprises an isolated switch, a control mechanism, an automatic openingand closing execution mechanism and a manual opening and closing mechanism, wherein the control mechanism comprises a remote control terminal, a control cabinet, a controller and an operation panel;the automatic opening and closing execution mechanism comprises a first supporting plate, an insulated rod, a spring and an electric drive pusher; the manual opening and closing mechanism comprises apull rope. In the actual application, opening or closing of the isolated switch on a tower can be realized by operating the remote control terminal, operating the operation panel on the ground or pulling the pull rope, so that working intensity of a worker is greatly reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an isolating knife switch device based on an automatic pulling function. Background technique [0002] When the line branch line is powered off for maintenance and defect elimination work, the staff need to operate the switch and isolation knife switch that controls the branch line. The staff uses the insulating operating rod to pull the isolation knife switch, so that the main line and the branch line have a clear disconnection point. . The isolating knife switch is a kind of high-voltage switch. It plays an important role in isolating the power supply, changing the operating mode of the system, switching on and off the small load current, and performing switching operations in the operation of the power system. The main function is that when the circuit breaker disconnects the circuit, Due to the disconnection of the isolation knife switch, the active and non-electrical parts can be clearly isolated and act as an auxiliary s...

AI Technical Summary

Problems solved by technology

The high-voltage isolation switch is a device that disconnects or connects high-voltage lines under no-load conditions, and electrically isolates electrical equipment such as high-voltage busbars and circuit breakers that are being repaired from live high-voltage lines. There is a lot of work to close the isolation knife switch, which causes a heavy workload for the staff, and when the isolation knife switch is at a high position, the staff can only work on the pole or use a crane to work, which brings inconvenience and safety risks to the staff and poses a threat to maintenance. , Elimination of power outages increases the difficulty
