A support structure for a HVDC disconnector is disclosed. The support structure comprises a support insulator having a body enclosing a chamber; an insulating gas provided in the chamber; and a first flange and a second flange positioned at opposite ends of the support insulator. A rotating insulator may be positioned in the chamber.

The invention relates to a device for measuring temperature in a high-voltage portion of a switchgear station, characterised in that it comprises: at least one temperature sensor () located at a point on the high-voltage portion of which the temperature is to be monitored, at least one antenna () connected to the at least one temperature sensor, a control module () located in a low-voltage portion of the switchgear station, and at least one antenna () connected to the control module. The at least one temperature sensor () is suitable for transmitting a signal representative of a temperature measurement and the control module () is suitable for receiving the representative signal, via the antennas, and for processing said signal in order to produce a message.

A HVDC disconnector is disclosed. The HVDC disconnector comprises a fixed contact comprising a guide and a pair of conducting members positioned in the guide wherein the first and second conducting members are both tulip contacts; a movable contact comprising a fixed arm and a mobile arm having a conducting terminal, wherein the mobile arm is movable from an open position to a closed position to close a connection between the fixed contact and the second contact.

This invention relates to a supporting structure for contacts of high-voltage disconnectors, characterized in that it comprises at least one vertical central composite insulator that is stayed by means of at least two inclined insulators, each of which is coupled at a first end to said at least one central composite insulator and at the second opposite end to a base body for said at least one vertical central composite insulator.

Supporting structure for contacts of high-voltage disconnectors

A disconnector for high voltage, including columnar supporting elements which are electrically isolating and are adapted to support electromechanical elements of opening and closing a circuit or an electrical line. At least one columnar supporting element, which is tubular, supports an optical current transformer, the optical fiber of which, surrounded by protection elements, extends inside the tubular columnar supporting element.

Disconnector for high voltage

A disconnector, including a crossmember, which has contact pins at its opposite ends, C-shaped contact sockets, which are aligned so as to correspond to the pins in order to receive them by insertion, along a trajectory that is circumferential with respect to a first rotation axis of the crossmember, which is substantially transverse thereto, a support of the crossmember that defines for it the first rotation axis, and a second rotation axis, which is substantially longitudinal to the crossmember, elements for the rotation of the crossmember about the first rotation axis and about the second rotation axis, where fixed contacts are connected electrically, in two separate regions, to supporting arms that belong to the sockets, and have a portion that is intermediate with respect to the two regions, is adapted for contact with the moving contacts, and divides the fixed contacts into two opposite conducting arms.

Disconnector, particularly of the double-break double-movement type

An actuation control, for electrical disconnectors, including a device for driving the actuation motor of a movable element of an electrical disconnector, elements for detecting operating parameters of the disconnector, a device for processing the operating and control parameters of the driving device, elements for storing the operating parameters, which are connected to the processing and control device in order to receive from it and store the processed operating parameters, and interface elements of the actuation control, for its activation for opening or closing the disconnector.
