    Abstract: It relates to a temperature sensing device and a switchgear. The temperature sensing device comprises: at least one sensor module (1) comprising a temperature sensor (12) and a wire (15), the temperature sensor (12) being configured to measure a temperature of a current carrying conductor and transmit the measured temperature via the wire (15), wherein a first end of the wire (15) is connected to the temperature sensor (12) and a second end of the wire (15) is provided with a first connector (150); and an electronic module (3) configured to receive the measured temperature from the at least one sensor module (1) and comprising a second connector (31) capable of being connected to the first connector (150). Due to the use of the first and second connectors (150,31), the sensor module (1) and the electronic module (3) can be assembled or disassembled in a simple way.

    Abstract: Embodiments of the present disclosure relate to a method for managing a breaker and a controller of a breaker. In the method, at least one test time interval is obtained, the at least one test time interval is between at least one actuation point and at least one change point for at least one test current that is caused by applying at least one test voltage to a coil of the breaker. A change point is detected for an actual current that is caused by applying an actual voltage to the coil. An actuation point is determined for the actual current at least based on the change point for the actual current and the at least one test time interval. With these embodiments, the actuation point may be determined in a simple way without a need of a voltage sensor being deployed in the breaker.

    Abstract: A sensing apparatus and a sensing method are provided. The sensing apparatus (100) comprises a current sensing circuit (104) configured to sense a secondary current generated from a current transformer (102) to generate a secondary current signal representing the secondary current, the current transformer (102) being configured to receive a primary current from a bus bar to generate the secondary current for supplying a power to the sensing apparatus (100); and a controller (106) configured to detect a peak value of the secondary current signal during a saturation of the current transformer (102), and configured to measure the primary current based on the peak value of the secondary current signal by a look-up table.

    Abstract: Embodiments of the present disclosure provide a method for monitoring a circuit breaker, comprising the following steps: obtaining a characteristic force associated with an actuating mechanism of the circuit breaker over the time; and determining the time point when the closing and/or opening of the circuit breaker occurs by identifying a variation of the force. The step of determining further comprises determining the moment when a variation increase of the characteristic force occurs as the time point of the closing of the circuit breaker; and determining the moment when a variation decrease of the characteristic force occurs as the time point of the opening of the circuit breaker. The method can be used to accurately on-line monitor the closing and opening time point 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).
