MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202627025630 A) filed by Xiamen Hongfa Electric Power Controls Co. , Ltd. on March 04, 2026, for Vacuum Circuit Breaker.

Inventors include Zhuang, Zhijian; Zhong, Shuming; Guo, Lunduo; and Cao, Xiaojun.

The application for the patent was published on August 07, 2026, under issue no. 32/2026.

Abstract: Provided in the present disclosure is a vacuum circuit breaker, comprising: a solid-insulation-embedded pole (200). The solid-insulation-embedded pole (200) comprises a static conductive assembly (210) and a dynamic conductive assembly (220), the dynamic conductive assembly (220) being configured to adjustably move towards the static conductive assembly (210) and come into contact with the static conductive assembly (210) thus realizing a closing action of the vacuum circuit breaker. The solid-insulation-embedded pole (200) further comprises an energy-absorption buffering mechanism, the energy-absorption buffering mechanism comprising a first movable member and a second movable member, wherein the first movable member is located on the side of the static conductive assembly (210) facing away from the dynamic conductive assembly (220), and the second movable member is located on the side of the static conductive assembly (210) facing away from the dynamic conductive assembly (220) and is movably connected to the static conductive assembly (210), the second movable member being movably connected to the first movable member; the energy-absorption buffering mechanism is used for absorbing impact energy generated when the static conductive assembly (210) comes into contact with the dynamic conductive assembly (220). By means of the above design, the present disclosure uses the design of movable connection between the first movable member and static conductive assembly (210) and the design of movable connection between the second movable member and first movable member to construct a buffering structure having two degrees of freedom, thus achieving a buffer function in the aforementioned two degrees of freedom.
