Problems solved by technology

However, since the connecting rod is a straight rod, one end of the connecting rod hangs high in the air when the gate is opened, and the insulating support of the moving contact must bear a large torque, which affects the stability of use; at the same time, when used in ultra-high voltage lines, the volume of the disconnector Very large, it takes up a lot of space after opening, and the wind resistance is weakened; the huge volume and long connecting rod make the inertial impact force large when opening and closing, which is easy to cause mechanical damage; the speed of opening is slow, which does not meet the requirements. Opening and closing characteristic requirements
At the same time, the traditional vertical disconnection switch adopts multiple sets of crank arm drive mode, which has complex structure, poor stability, and large action error, which may easily cause improper action or over-action

Abstract

The invention relates to a disconnecting switch, especially the double fractures folding vertical separated switch used in extra-high tension or high tension electrified wire netting. It uses folding connecting link in the structure of parallelogram to replace the common vertical-breaking separated straight connecting link, and instead of the bended arm, it uses wheel gear to transfer actuator force. The invention increases the accuracy and stability of movement of product. Since the structure of double fractures, the altitude of space is reduced; while in the same power, the speed of detaching brake and the frequency of effective application are markedly increased.

Description

Technical field [0001] The invention relates to an isolating switch, in particular to a double-break foldable vertical switching isolating switch for ultra-high voltage or ultra-high voltage power grids. Background technique [0002] Vertical disconnect switch is a common equipment used in ultra-high voltage substations. Its working principle is to use a connecting rod set on each phase line that can be rotated vertically 90 degrees to connect the end. The connecting rod is a fixed straight rod. , Rotate the connecting rod to insert the contact into the contact terminal when closing, and rotate the connecting rod 90 degrees to lift it when opening. But because the connecting rod is a straight rod, one end of the connecting rod hangs high in the air when opening, the movable contact insulation pillar has to withstand greater torsion, which affects the stability of use; at the same time, when used in ultra-high voltage lines, the volume of the isolating switch Very large, it takes ...
