Abstract: A fault diagnosis apparatus (100) and method (1200) for a circuit breaker (200), comprises at least one sensor (101) coupled to at least one mechanism (201) arranged in the circuit breaker (200) and configured to obtain waveform data of a parameter over time, the waveform data related to an operation state of the at least one mechanism (201); and a processing unit (102) coupled to the at least one sensor (101) and configured to analyze the waveform data to obtain at least one feature value (1220); determine a dissimilarity between the at least one feature value and a threshold matrix (1230); and in response to the dissimilarity being greater than a threshold dissimilarity, determine that the at least one mechanism (201) has a fault (1240). With the fault diagnosis apparatus (100), the fault in the at least one mechanism (201) of the circuit breaker (200) may be determined in advance.

Abstract: An apparatus and a method for monitoring a temperature of a cable joint (201) of a cable (200) connected to a gas insulated switchgear (300). The apparatus comprises an adaptor (101) adapted to be coupled to a cable socket (31) of the switchgear, the cable socket being provided with a mounting hole (311) for connecting the cable joint, the mounting hole being provided at a mounting surface (312), wherein the adaptor, when coupled to the cable socket, is situated at the mounting surface and outside the mounting hole; a temperature sensor (102) arranged in the adaptor and configured to detect a temperature of the adaptor; and a processor (103) configured to determine the temperature of the cable joint based on the detected temperature of the adaptor. Then the temperature of the cable joint may be determined conveniently and precisely.

Abstract: It provides a method for monitoring a circuit breaker and an apparatus and an internet of things using the same. The method includes: obtaining a first data set representing force applied to a fixed point of an element of an actuating mechanism of the circuit breaker in present operation cycle, judging a health condition of the circuit breaker in consideration of normal operating condition related parameters of the element according to a history profile when the circuit breaker operated normally and current operating condition related parameters of the element in the present operation cycle extracted from the force represented by the first data set, and generating a signal indicating the health condition of the actuating mechanism of the circuit breaker the circuit breaker. The force applied to the fixed point of the actuating mechanism of the circuit breaker, which corresponds to a health condition of mechanical parts of the circuit breaker as a whole, is selected as an indicator for condition monitoring of the mechanical parts of the circuit breaker. The operating condition related parameters derived from the measurements of the force are considered giving a relatively high accurate judgement of the whole mechanical parts of the circuit breaker.

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).
