    摘要: The invention relates to a method of protecting against circuit breaker failure, said circuit breaker having contacts capable of moving between a closed position and an open position, and vice versa, and being fitted with protection apparatus including fault detector apparatus for putting into operation an opening electromagnetic coil that actuates circuit breaker contact drive apparatus, with position-indicator contacts of monitor apparatus being changed over as soon as the circuit breaker contacts start to move. According to the invention, in the event of a fault being detected, a time delay is generated from the indicator contacts changing over, and at the end of said time delay it is verified whether the fault current has become zero, and if not an alarm is generated.

    摘要: A density sensor for monitoring a rate of leakage from the case of electrical switchgear filled with dielectric gas under pressure, the sensor comprising a fixing support mounted from the outside in the thickness of the case and communicating with the dielectric gas. A radiator is placed around the fixing support of the density sensor, thereby enabling a measurement artifact that is due to the exposure of the case and of the sensor to solar radiation to be transformed in such a manner that any risk of untimely crossing of a low density threshold is eliminated.

    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.

    摘要: A method and a differential protection apparatus for an electrical link in a medium, high or very high voltage power distribution network. This method, in which two differential protection devices are disposed at the two ends (A, B) of said link, includes a step during which a comparison is made between the current measured locally and the current measured remotely, after said devices have been resynchronized by phase shifting the data received from the end situated remotely by one half of the sum of the outward and return propagation times; and a second step during which, if an angular phase difference is found to exist between two currents after resynchronization, automatic compensation is effected by servocontrolling the angle of the current vectors.

    摘要: The present invention relates to a method of monitoring electrical wear on selector switch disconnectors in a bay of a high voltage station that includes a set of distribution busbars connected to at least three electrical circuits constituted by an inlet bay, an outlet bay, and a bay for coupling together the busbars. During an operation of transferring a bay under load, when the computer of the corresponding bay detects that the disconnectors of its lines for connection to the distribution busbars are closed, the computer sends a message to the other computers which then determine and store data comprising the magnitude and the polarity of the current flowing through the corresponding bays, and when the computer of the bay in which transfer is taking place has detected opening of the selector switch disconnector in the line for connection to the busbar from which distribution has been transferred, said data prior to the opening is stored and the square of the current interrupted by said disconnector is calculated.

    摘要: A method of discriminating an arc detected in metal-clad equipment includes detecting an arc, generating an arc-appearance signal, transmitting the arc-appearance signal to a computer, and determining a time lapse T. The time lapse T is determined according to the formula t.sub.o -t.sub.a ; t.sub.o is an instant at which the computer receives a circuit breaker trigger order, and t.sub.a is an instant at which the arc-appearance signal is first acquired by the computer. The arc is determined to be an internal arc (1) if the time lapse T is positive, or (2) if the time lapse T is negative and its absolute value is less than or equal to 10 ms. On the other hand, if the time lapse T is negative and its absolute value is greater than 10 ms, variation of the arc-appearance signal is analyzed to discriminate the arc.

    摘要: A metal-clad modular power-supply station comprising a main set of busbars interconnecting at least two pairs of components, such as overhead feedthroughs or cable boxes, in an H-station configuration. The components are connected together in pairs by respective rectilinear groups of metal-clad electrical apparatuses that are parallel to and connected to the main set of busbars. Preferably, the groups of electrical apparatuses are in alignment. The length of the set of busbars is thus reduced while complying with the laid-down isolation distances and a station is provided of minimum size and of reduced cost.
