Abstract
This utility model relates to the field of overvoltage protection devices and discloses an overvoltage protection device with a disconnection device. It includes a base, with insulators at both ends of the upper surface of the base. A mounting base is fixedly connected to the upper surface of the insulator on the right side, and a gate seat is fixedly connected to the upper surface of the insulator on the left side. A knife switch is hinged to the outer wall of the mounting base. A disconnection mechanism is provided on the inner surface of the base, and a switch assembly is provided on the upper surface of the base. The disconnection mechanism includes a positioning component, which includes a rotating rod. In this utility model, the positioning component of the disconnection mechanism, in cooperation with the engaging component, allows for manual disconnection of the gate seat and the knife switch. Furthermore, the locking groove and locking block prevent accidental opening and closing, ensuring stable connection between the knife switch and the gate seat during use and ensuring safe circuit disconnection during maintenance, avoiding reconnection due to external force, thus improving operational convenience and safety.
