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.

Disclosed herein is a monitoring probe for observing groundwater, which is put into an observation well for observing the groundwater to indicate a position of a fresh water-salt water interface of the groundwater. According to the present invention, both ends of a probe body are separated from an inner circumference of an observation well by a catch preventing portion having a convex curved portion or a dumbbell-shaped portion, so that the probe body can be smoothly moved up and down without being caught by a ground-water inlet port of the observation well, thus providing an exact position of a fresh water-salt water interface.

摘要:
Die Erfindung betrifft eine Füllstandsmeßvorrichtung, zur Messung des Füllstands eines in einem Behälter (1) befindlichen Mediums (2), mit einem Referenzbehälter (3), der derart mit dem Behälter (1) verbindbar ist, daß der Füllstand in dem Referenzbehälter (3) dem Füllstand in dem Behälter (I) entspricht, wobei der Referenzbehälter (3) eine Anschlußvorrichtung (6) für ein nach dem Radar-Prinzip arbeitendes Mikrowellen-Füllstandsmeßgerät (7) aufweist. Erfindungsgemäß ist vorgesehen, daß die Anschlußvorrichtung (6) eine Einkoppeleinrichtung (8) für ein Mikrowellensignal aufweist. Damit wird eine kostengünstige Lösung für den Anschluß eines Mikrowellen-Füllstanduneßgeräts (7) an einen Referenzbehälter erzielt, mit der eine optimierte Signaleinkopplung gewährleistet wird.
