Document Type and Number:
WIPO Patent Application WO/2020/228427
Kind Code:
A1
Abstract:
Disclosed is a non-contact arc current closing auxiliary contact device for isolation switches, comprising a static contact mechanism and a moving contact mechanism. A discharge mechanism is provided between the static contact mechanism and the moving contact mechanism. The static contact mechanism comprises a first insulating prop, a mounting frame, and a static contact. The mounting frame is provided on the first insulating prop, and the static contact is provided on the mounting frame. The moving contact mechanism comprises a second insulating prop and a conducting rod. A driving device is provided on the second insulating prop. One end of the conducting rod is provided with a moving contact, and the other end of the conducting rod is transmittingly connected to the driving device to drive the moving contact and the static contact to perform opening or closing. The discharge mechanism comprises a static arc striking rod and a moving arc striking rod. One end of the moving arc striking rod is connected to the conducting rod, and the other end extends and goes beyond the end face of the moving contact. One end of the static arc striking rod is fixedly connected to the mounting frame, and the other end extends towards the moving arc striking rod and goes beyond the end face of the static contact.
