摘要： An intelligent integrated medium-voltage alternating current (AC) vacuum switchgear based on a flexible switching-closing technology comprises a controller (24), and a vacuum switching tube (1), an insulator (9), and an switching-closing mechanism connecting piece (15), which are connected in sequence. A microprocessor is built in an intelligent circuit (23); a travel sensor is fixed to a movable contact connecting rod (5), and directly detects a motion state of a movable contact (4) and acquires accurate motion parameters of the movable contact (4); switching-closing operating parameters are obtained by comprehensively calculating arc light intensity detected by an arc light transmitter (20) and a temperature measured by an infrared temperature measuring transmitter (22), such that the switching-closing performance of switching on and switching off a medium-voltage power grid is greatly improved, switching-closing time points can be accurately controlled, and “flexible” switching-closing is achieved.

摘要： A device for detecting and locating at least one electric discharge in equipment insulated by fluid contained in an electrically-conductive housing. The equipment includes a plurality of grounding lines connected between the housing and ground. The device includes a plurality of Rogowski coil type current detectors and a mechanism synchronously comparing signals delivered by the current detectors. The coil of each detector is placed around a respective one of the lines. Each detector delivers a signal representative of current flowing in the line, with occurrence of an electric discharge giving rise to a sudden variation in the current, and with electric discharge being located within an inside zone of the housing situated in proximity of the line that is surrounded by the detector that was first to deliver the sudden variation of current.

摘要： Capacitors (5a, 5b) are provided in the insulators of bushings (4a, 4b), respectively. One ends of the capacitors (5a, 5b) are connected to central conductors (3a, 3b) side, and the other ends are connected to a tank (1) side at the ground potential. When a discharge signal from the outside of the tank (1) reaches the capacitors (5a, 5b) through the central conductors (3a, 3b), the capacitors (5a, 5b) work as a filter to attenuate and prevent the signal in the frequency band of the discharge waveform from propagating to the inside of the tank (1). When an antenna (7) placed in the tank (1) receives a signal in the frequency band of the discharge waveform, a discharge detection unit (20) determines that a discharge inside the tank has been detected.

摘要： The method relates to discriminating between an internal arc and a circuit-breaking arc established in the enclosure of a circuit breaker in a bay of a medium or high voltage metal-clad substation. The appearance of an internal arc is detected by a protection system which responds by transmitting a disengagement order to the circuit breaker, thereby causing a circuit-breaking arc to appear. The pressure of the dielectric gas inside the enclosure of the circuit breaker, is continuously measured and recorded so that after the instant at which the disengagement order is transmitted, it is possible to recover a first pressure value measured before the instant. The first pressure value is then compared with a second pressure value measured after the said instant in order to identify whether the internal arc was struck in the circuit breaker enclosure.
