Communication device comprising a mounting structure and valve unit
A communication device can be used for communicating between a power equipment controller and power equipment devices of a high-voltage power electronics system. The communication device includes a controller interface communicatively coupled with the power equipment controller, an RF module coupled to the controller interface, and an antenna port coupled to the RF module. A mounting structure is configured to attach the communication device to a valve hall containing the power equipment devices. The mounting structure is permeable for RF signal communication between the communication device and power equipment devices in the valve hall. The mounting structure has a low voltage side to enable placement of the controller interface, the RF module and the antenna port so as to be shielded from disturbances due to high voltages inside the valve hall.
