Problems solved by technology

[0003]The SF6 gas in the existing sectionalizer box will leak, so the sealing performance of the box needs to be improved
[0004]Secondly, the opening and closing control of the existing sectionalizer is not timely enough, which affects the use effect
[0005]In addition, the existing outdoor pole-mounted switch electromagnetic tripping generally requires an external voltage transformer (PT) to provide energy for it. Due to PT failure, the switch often fails to work normally The situation; and the external PT also increased the project cost

Abstract

The invention relates to improvement of a sectionalizer structure and provides an outdoor alternating current high-voltage SF6 automatic sectionalizer which is good in sealing property and capable of dividing and shutting a brake timely. The sectionalizer comprises a box body. SF6 gas is filled in the box body. A rotating shaft is arranged in the middle of the box body. A moving contact is arranged on the rotating shaft. An insulator is arranged on the box body. One end of the insulator extends into the box body and a static contact corresponding to the moving contact is arranged at one end of the insulator. A wiring terminal is arranged at the other end of the insulator. The wiring terminal and the static contact are connected through a conducting rod. The sectionalizer is characterized in that one end of the rotating shaft is connected with a spring mechanism driving a rotating shaft outside the box body to rotate through a magnetic fluid sealing shaft head, an energy storage handle and a divide-shut brake electric buckle releasing device which are used for driving the spring mechanism are arranged outside the spring mechanism, a controlled port of the divide-shut brake electric buckle releasing device is connected with an output controlled port of an electronic controller, and the electronic controller detects current intensity in an upper stage line and controls motion of the divide-shut brake electric buckle releasing device.

Description

technical field [0001] The present invention relates to the improvement of the segmenter structure. Background technique [0002] The sectionalizer is a switching device that cooperates with the front-end switch on the power supply side and automatically opens when there is no voltage or no current. When a permanent fault occurs, the sectionalizer will be locked in the opening state after a predetermined number of opening and closing operations, so as to achieve the purpose of isolating the faulty line section. [0003] The SF6 gas in the box of the existing sectionalizer may leak, so the sealing performance of the box needs to be improved. [0004] Secondly, the opening and closing control of the existing sectionalizer is not timely enough, which affects the use effect. [0005] In addition, the electromagnetic tripping of the existing outdoor pole-mounted switch generally requires an external voltage transformer (PT) to provide energy for it. Due to the failure of the PT...
