Abstract
Some embodiments relate to a switchgear is disclosed, which comprises a tank system filled with an insulating gas and a switching device and at least one electronic sensor within the tank system. Moreover, the switchgear comprises a contactless power transmission system with a power transmitter outside of the tank system and with a power receiver within the tank system, wherein the power receiver is coupled to the power transmitter. Further on, the power receiver is electrically connected to the electronic sensor and designed to supply electric power to the same.
Claims15
A Switchgear, comprising a tank system filled with an insulating gas and comprising a switching device and at least one electronic sensor within the tank system,
- a contactless power transmission system with an electromagnetic power transmitter outside of the tank system and with an electromagnetic power receiver within the tank system, wherein
- the electromagnetic power transmitter is designed to receive electric power (P) from a power source and to convert it into an electrically non-conductive form of power,
- the electromagnetic power receiver is coupled to the power electromagnetic transmitter and designed to receive the electrically non-conductive form of power from the power transmitter and designed to convert it into electric power (P),
- the power receiver is electrically connected to the electronic sensor (7) and designed to supply electric power (P) to the same,
- load modulation means connected to the electromagnetic power receiver,
- current sensing means connected to the electromagnetic power transmitter,
- a microcontroller with a microcontroller input and a microcontroller output,
- wherein the microcontroller is connected to the electronic sensor and designed to receive measurement data from the electronic sensor via its microcontroller input,
- wherein the microcontroller output is connected to the load modulation means and wherein the microcontroller is designed to send measurement data to the load modulation means via its microcontroller output, and
- wherein the current sensing means are designed to receive measurement data from the electromagnetic power receiver.
