Abstract

This invention discloses a high-voltage AC electrical signal isolating switch. The isolating switch includes a moving knife assembly and two connecting parts disposed on the moving knife assembly. One end of the moving knife assembly is configured as a rotating end, and the other end is configured as a moving end. The rotating end and the moving end of the moving knife assembly are respectively located on two stationary contacts. This invention has the following beneficial effects: Through the two stationary contacts and the isolating switch disposed on the stationary contacts, the synchronous and stable switching of the stationary contacts of the two electrical signals is realized. This design overcomes the shortcomings of traditional high-voltage knife switches, such as large operating force and difficulty in remote control. At the same time, it avoids the defects of wireless remote control switches that rely on external power and require regular maintenance. The structure is compact and can achieve safe and convenient manual operation in high-voltage environments without external power supply. It significantly improves the reliability, convenience and installation adaptability of the high-voltage signal control link, and better meets the requirements of intelligent and high-reliability equipment in the context of the power Internet of Things.
