A disconnector to reduce considerably high voltage and high frequency current generated during the service no-load opening and closing,

High frequency transients suppression for hvdisconnectors with sliding resistor

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.

Temperature measurement in switchgear stations

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.

Actuation control and control method, particularly for electrical disconnectors
