Vacuum thermally-fixed capacitor element with high-temperature early warning function

The utility model discloses a vacuum thermal capacitor element with a high temperature early warning function, comprising a capacitor body, the surface of the capacitor body is sleeved with a fixing ring, the left and right sides of the top of the fixing ring are both glued with plugging shells, and the opposite sides of the left and right plugging shells are both welded with positioning mechanisms. A mounting mechanism is inserted in an inner cavity of the inserting shell, a temperature measuring mechanism is connected to the bottom of the mounting mechanism through bolts, an early warning lamp is connected to the top of the mounting mechanism through bolts, the positioning mechanism comprises a fixed shell, and a movable plate is movably connected to an inner cavity of the fixed shell; positioning pins are welded to the opposite sides of the left movable plate and the right movable plate. Through cooperative use of the temperature sensor, the controller and the early warning lamp, the capacitor temperature
