Monitoring - and evaluation device and method for the determination of a lsoliergasmenge in gas-insulated switching installations as well as in test systems, for switching installations

摘要

The invention relates to a monitoring - and evaluation unit for the determination of an insulating gas quantity in gas-insulated switching installations as well as in test systems, for switching installations, based on a monitor the filling level of the insulating gas is filled with insulating gas in the modules of the switching system or of the test system, with an input device (10) for the input variables determined in advance with respect to pressure and filling quantity of in the modules of the gas-insulated switching installation of the insulating gas, with a measuring unit (20) which continuously the amount of the insulating gas in the gas-insulated modules of the switchgear assembly is determined, wherein said input means (10) and the measuring unit (20) with a monitoring system (30) are connected. The filling quantity in the modules is filled with insulating gas from the measured pressure in the modules is filled with insulating gas, as well as the existing volume in the modules can be determined for the insulating gas. From the previously determined quantity of the insulating gas and the continuously determined insulating gas quantity is filled with insulating gas in the modules of the switching system or of the test system in the monitoring system (30) is a from the modules is filled with insulating gas escaping from the insulating gas quantity ermitteltbar gas balances in an automated manner, and from this are based on the insulating gas amount, can.
