Abstract
The electrical equipment comprises electrical elements corresponding to at least one phase of the distribution network and housed in a tank. The equipment is insulated with a dielectric liquid wherein the elements are immersed. The equipment comprises an input for each phase in the tank, and also a protection device, associated with at least one failure detector and configured so that, in the event of detecting such a failure, a short circuit will be established in the phases. The protection device is situated so as to establish the short circuit in a position before any protection, control or transformer element of the electrical equipment.
Claims29
An electrical equipment device of an electricity distribution network, the device comprising:
- a tank insulated with an insulation comprising a dielectric liquid, wherein the liquid at least partially fills the tank, the tank having a circuit to generate a signal based on at least one input phase;
- an input for each phase;
- an output;
- an electrical path connecting the inputs and the output;
- an over-current protection device on the electrical path between the one or more inputs and the output;
- and
- a short-circuiting device associated with at least one failure detector, configured to detect a failure due to a fault in the insulation, the short-circuiting device being configured to establish a short circuit in the one or more phases if there is an event indicative of the detection of the failure, wherein no over-current protection device, no control element, and no transformer is on the path between the short circuit and the input, wherein the short-circuiting device is configured to establish the short circuit independent of the function of the over-current protection device, and the short circuit does not cause an over-current condition in the over-current protection device.
