    摘要: Le disjoncteur est constitué par deux boîtiers moulés multipolaires standards accolés, de la résine (68) étant coulée à froid entre les parois latérales opposées, comportant des dépouilles (56,60), des deux boîtiers de manière à en assurer la fixation. Une entretoise (62), fixée par vis aux parois latérales des deux boîtiers, en définit l'écartement et peut être utilisée pour coopérer avec une came d'embrochage (74) lors de l'embrochage du disjoncteur dans un châssis fixe (42). Le disjoncteur comporte un déclencheur électronique, un mécanisme de commande et un barreau de commande des pôles communs à l'ensemble des pôles. Au moins deux pôles adjacents sont jumelés, c'est à dire connectés électriquement en parallèle.

    摘要: On opening of a circuit breaker, an end portion 19 of a pivotable contact arm 12 disengages from fixed contacts 7 such that an arc is drawn therebetween radially across the pole face of a field coil 9, the end portion 19 moving transversely to the field coil axis. The arc then transfers from the contacts 7 to a tubular electrode 24 thereby bringing the field coil 9 into circuit so that a magnetic field is generated which causes the arc to rotate and become extinguished. In the fully-open position of the circuit breaker, the end portion 19 lies along the field coil axis. The whole assembly is disposed in a housing 2 which contains the highly insulating gas sulphur hexafluoride. A single field coil and electrode can be shared between two such constructions. Arrangements are also disclosed (Figures 11 to 14) in which the initial arc is drawn directly between the contact arm 12 and the electrode 24.

    摘要: The present invention relates to a system (10) for monitoring a switchgear, the system comprising:
    - at least one temperature sensor (20);
    - a processing unit (30); and
    - an output unit (40).
    The at least one temperature sensor is configured to acquire temperature data for each location of at least one location of a switchgear (50) at n time points. The at least one temperature sensor is configured to provide the temperature data to the processing unit. The processing unit is configured to determine n-1 rates of change of temperature for one or more locations of the at least one location with respect to the n temperature data for the one or more locations at the n time points. The processing unit is configured to determine a state of the switchgear, wherein the determination of the state of the switchgear comprises utilization of the n-1 rates of change of temperature for the one or more locations and at least n-1 of the n temperature data for the one or more locations. The output unit is configured to output the determined state of the switchgear when the determined state of the switchgear is determined not to be normal or not to be healthy.

    摘要: The invention relates to a current transformer for high voltage gas insulated switchgear substation, wherein the the current transformer is arranged in a tubelike insulating housing, which is connected with a fastening flange at both ends of the tubelike housing, according to the preamble of claim 1. In order to enhance the connection of the aforesaid two flanges, in order result in high level mechanical stability and sealing, the invention is, that the aforesaid flanges are fixed to the insulating tubelike housing (1) by glueing in that way, that both flanges (2) are provided with a peg-like portion (2*), whose external diameter corresponds with the inner diameter of the insulating tubelike housing (1), in such, that the peg-like portion is pushed tightly into the insulating housing, and that the intersurface between both corresponding surfaces is provided with a glue.
