Document Type and Number:
WIPO Patent Application WO/2024/092956
Kind Code:
A1
Abstract:
Disclosed in the present invention is a small-size high-voltage direct current contactor, comprising a main contact assembly, an auxiliary contact assembly and a push rod assembly. The upper end of the push rod assembly is respectively connected to the main contact assembly and the auxiliary contact assembly to drive and control the main contact assembly and the auxiliary contact assembly to perform working state switching, respectively; a mounting frame is provided to cover outside the upper end of the push rod assembly; a first mounting structure used for bearing and limiting the auxiliary contact assembly is arranged on the side vertical wall of the mounting frame; and the auxiliary contact assembly can be formed into a normally-closed auxiliary contact assembly by means of the combination of the first mounting structure and the push rod assembly. The high-voltage direct current contactor has a novel and reasonable structure, a small size, controllability and high universality and applicability, and can satisfy the use requirements for high-voltage direct current contactors in different working scenarios; in addition, the high-voltage direct current contactor is easy to process and install, so that the assembly efficiency and the assembly precision are improved.
