    Abstract: A motor apparatus for a high voltage switch device, comprising a brushless DC motor (20), a drive and control apparatus (30), and a speed reduction apparatus (40). The brushless DC motor (20) comprises a rotor (202) and a stator (203). The rotor (202) is sleeved in the stator (203) and mounted in a motor housing (201). Two ends of the rotor (202) are respectively sleeved with rolling bearings (204), and the bearings (204) are sleeved on a motor drive shaft (208). The drive and control apparatus (30) comprises a microprocessor (301), a semiconductor switch (302), and a power supply module (303) for powering the microprocessor (301). The microprocessor (301) controls the start, stop, and forward and reverse rotation of the brushless DC motor (20) via the semiconductor switch (302). The speed reducer (40) comprises a gear transmission system (401) composed of a plurality of mutually meshing gears as well as an output shaft (402). The gear transmission system (401) transmits motion of the motor drive shaft (208) to the output shaft (402).

    Abstract: A pivot supporting structure for a circuit breaker and a circuit breaker. The pivot supporting structure comprises: a supporting body having a supporting hole for receiving and pivotally supporting a pivot pin connected to an actuating mechanism of the circuit breaker, wherein at least one strain gauge are mounted to the supporting body for sensing the force acting on the pivot supporting structure by the actuating mechanism. This pivot supporting structure can accurately sense the characteristic force applied, such that the contact force and mechanical characteristics of the circuit breaker can be on-line monitored.

    Abstract: Disclosed is a fuse device with a micro-powered switch comprising a micro-powered switch (2), a fuse device interlocking mechanism (5), a fuse wire striker pin assembly (6) and a connecting rod (7), wherein the fuse wire striker pin assembly (6) comprises a main shaft (601), striker pin pieces (602) and trigger pieces (603); the striker pin pieces (602) and the trigger pieces (603) are radially fixed on the main shaft (601), and can axially move around the main shaft (601); and when one or more fuse wires are not installed, or when one or more fuse wires have fused, the fuse device interlocking mechanism (5) cooperates with the fuse wire striker pin assembly (6) and drives the connecting rod (7) to trigger the micro-powered switch (2), whereby the switch device cannot close. The fuse device with a micro-powered switch has a simpler structure, effectively reducing production costs, and the modularised assembly saves on assembly time.
