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.
Claims27
An electrical equipment device of an electricity distribution network, the device comprising:
- at least one electrical element corresponding to at least one phase of the distribution network and housed in a tank, the device being insulated with a dielectric liquid wherein the electrical element is immersed and which, at least partially, fills the tank;
- an input for each phase in the tank;
- 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 phases if there is an event indicative of the detection of the failure, wherein the short circuit is located along an electrical path before any of a over-current protection device, a control element, and a transformer.
