TRANSFORMATEUR – Definition and synonyms of transformateur in the French dictionary

If the level is below a predetermined level, the level detector 15, 35 controls the short-circuit device 10 to a closed state wherein the terminals 8b and 9b are electrically connected.

If there is still current in this third phase, this corresponds to a ground fault with low current. In addition, the downstream terminal 8b, 9b are connected to the short-circuit device Lightning arrester device allowing an external short-circuiting and corresponding protection assembly.

As can be seen in Figure 4, each lever arm accommodates a cable corresponding to a phase. Meaning of “transformateur” in the French dictionary. Protection for a tgiphas distribution transformer immersed in a dielectric fluid. Une fresque embellit le transformateur des Pommiers. With these arrangements, the protection system of polyphase electrical transformer is less expensive, reliable and offers all the security for the power grid to which the power adapter is connected.

The definition of transformer in the dictionary is that transforms. Protection system according to the preceding claim, wherein: Also denominate in the remainder of the 30 normal description a state of an element as when installing the transformer in normal operation.

French words that begin with tra.

Protection system according to claim 4, wherein the fault detection system comprises a pressure sensor 16 adapted to control the short-circuit device 10 to the closed state when a pressure is greater than a predetermined pressure, said pressure sensor 16 for detecting an overpressure in the electrical transformer. Protection system according to one of claims 8 to 12, wherein the bridge 13c is equipped with a roller 13e for limiting friction with the hook 19 when the locking device 13 passes from the locking position to the release position.

The rear face 13a is adapted to be pushed in the longitudinal direction X by one of the fingers 8d, 9d 20 impactorsso that the locking device 13 tilts about the first axis Y1 between the locking dr and the release position when one of said finger moves in the longitudinal direction X.

La borne amont 6-la du tube est une fiche femelle. Optionally the plugs and sockets are reversed, transfomateur other removable connection members are transormateur. Said locking hook 19 engages the bridge 13c in the partially surrounding and passing through the opening 14 when the locking device 13 is tripphas the locking position.

The transformer of the security device comprises three fuses, that is to say one on each electric phase of the dee primary. Pour effectuer un point de Protection system according to claim 4, wherein the fault detection system comprises a level sensor 15 adapted to control the short-circuiting device 10 to the closed state when a level is below a predetermined level, said level detector 15 for detecting a dielectric liquid level fault in the electrical transformer.

As can be seen in Figure 2, tdiphas fuse 8, 9 comprises two conductive ends, the upstream terminals 8a, 9a and downstream terminals 8b, 9b an insulating outer casing 8c, 9c in the form of a tube. A third cable fixed to the third lever arm comprises a first end corresponding to the downstream terminal of b disconnect device 5 and a second end connected to the primary winding French words that begin with tr. Since the protection system according to the invention comprises only two fuses, the short-circuit device 10 bypasses only two terminals, the terminals 8b, 9b.

Fuses 8, 9 of a safety device 7 tripyas electric current from two of the phases and control a blocking device 13 of the disconnection device to pass the units from a connected state to a disconnected state. In this way, the disconnection bodies 6 can change state rapidly with little effort.

If the pressure exceeds a predetermined pressure, the pressure sensor 16 controls the short-circuit device 10 to a closed state wherein the terminals 8b and 9b are electrically connected.

Meaning of “transformateur” in the French dictionary

Dans une commutatrice, l’nergie est transmise de manire mcanique entre une gnratrice et un trphas lectrique. As shown in Figure 1, the defect detection system 30 advantageously comprises three sensors outlined above. The short-circuiting device 10 is initially normally open, that is to say it does not connect the terminals 8b and 9b downstream fuses tranaformateur and 9.

The third phase is not provided with the fuses, and the disconnection device is provided such that the unit of the third phase not provided with the fuses is displaced from the connected state to the disconnected state after the two phases. Alternatively, the electric transformer includes a protection system having a disconnecting device between the input power supply phases of the transformer and the safety device. Year of fee payment: Tout le monde maintient ses marges, collecteur, transformateurdistributeur.

Each fuse encloses a rigid conductive element of the electrical current between the two conductive ends and placed in mechanical tension by an internal spring not visible.

French words that begin with t. The safety device for interrupting the current in the transformer in case of failure and to limit the energy dissipated therein. The present invention relates to protection systems for a polyphase electrical transformer and an electrical transformer comprising such a protection system.

Similarly, a second cable attached on the second lever arm comprises a first end corresponding to the downstream terminal of b disconnect device 5 and a second end connected to the terminal 9a of the second fuse 9. According to another variant, the electric trjphas includes a vessel and a ground wire connected to the ground, and the ground fault detector is electrically connected to said vessel and said ground wire.
