Abstract

The utility model provides a high-voltage switch contact pressure adjusting mechanism and a pressure sensor, and relates to the technical field of high-voltage switch equipment, and the high-voltage switch contact pressure adjusting mechanism comprises a first connecting seat connected with a high-voltage switch contact, a telescopic adjusting structure of the first connecting seat, and a limiting ring fixedly connected with the bottom of the surface of the telescopic adjusting structure. The top of the surface of the telescopic adjusting structure is movably connected with a pressure plate. The surface of the telescopic adjusting structure is sleeved with a reset spring, the reset spring is located between the pressure plate and the limiting ring, and the bottom of the left side of the telescopic adjusting structure is fixedly connected with a second connecting base movably connected with the high-voltage switchgear. Through the arrangement of the first connecting base, the telescopic adjusting structure, the limiting ring, the pressure plate, the reset spring and the second connecting base, the problems that a mechanical spring structure is mostly adopted for contact pressure adjustment of existing high-pressure switch pressure adjusting equipment, adjustment is inconvenient and low in precision, and meanwhile, shutdown disassembly is usually needed for pressure measurement, and real-time monitoring cannot be achieved are solved.
