摘要：
The invention describes a fault gas detection system (10) for a liquid filled high voltage transformer (1), the transformer (1) comprising a main tank (2) and an expansion tank (3) the tanks (2, 3) fluidic connected by an exchange conduit (4) such that gas (G) and/or a transformer liquid (TL) is able to exchange between the tanks (2, 3), the gas detection system (10) comprising:
- a chamber (11) with a top cover (12),
- a predefined horizontal level-plane (P) in the chamber (11) defining a maximum liquid level (L) of a transformer liquid (TL) in the chamber (11) during use,
- a fluid-channel (13) comprising a fluid-egress (15) at a level equal to or higher than the top cover (12) and a fluid-ingress (16) lower than the level of the level-plane (P),
- a level sensor (14) designed to measuring and/or indicating a liquid level (L).
The invention further describes a respective transformer and a respective wind turbine system.
