High-voltage direct-current voltage measuring system based on electrolyte voltage division

Abstract

The invention discloses a high-voltage direct-current voltage measuring system based on electrolyte voltage division; the system comprises a high-voltage direct-current power supply, an electric appliance, an electrolyte variable resistor, a voltmeter and a processing terminal; the processing terminal controls a capture fiber blanket of the electrolyte variable resistor to capture floccules and precipitates on the same layer of the capture fiber blanket in electrolyte; capture space is provided for captured floccules and sediments; an electric telescopic rod is controlled to be connected with a capture rubber sleeve in a sleeving manner to capture floccules and sediments on different layers in the electrolyte, and the floccules and sediments are fed on different layers into the capture fiber blanket for latching, so that the resistance value of the electrolyte is prevented from being influenced. According to the application, the problem that the resistance value of the electrolyte is influenced due to the concentration change of the electrolyte caused by floccules or precipitates formed by the electrolyte precipitation phenomenon of the electrolyte varistor due to long-time work in the use process of the electrolyte varistor is solved, and the measurement accuracy is greatly improved.
