Vertically Disconnecting High-voltage Disconnect Switches Have A Relatively Simple Structure.
hv isolator switch typically consists of main components such as supporting insulators, conductive blades, operating mechanisms, and fixed bases. When closed, the conductive blades are in close contact with the fixed contacts, isolating the live parts from the ground via the support insulators. The operating mechanism transmits external mechanical force to the moving contact, causing it to open and close vertically. The overall structural arrangement of high voltage electrical isolator ensures that the air gap dimensions between the various parts meet the design requirements to satisfy the dielectric performance under high voltage levels.
For vertical pull-out designs, the moving contact is directly pulled apart from the stationary contact vertically, with a clear and intuitive movement path. Some isolator high voltage circuits use a three-insulating support combination, achieving the breaking action by rotating the insulator. The mechanical transmission components of this method focus on ensuring the repeatability and mechanical life of the high voltage isolator action, while providing a clearly visible separation state at the break point.
