Electrolytic cell system grounding detection positioning method and detection device

Abstract

The application discloses an electrolytic cell system grounding detection positioning method and a detection device, and aims to provide an electrolytic cell system grounding detection positioning method which can quickly determine whether electrolytic cells are grounded and find the grounding position, and a detection device for realizing the method.The method is as follows: current transformers or wireless receiving coils are installed at the incoming line end and the outgoing line end of each electrolytic cell, and the grounding of a certain electrolytic cell is determined by detecting the size and direction of harmonic current and instantaneous capacitance current or the size and direction of the ground voltage of each electrolytic cell.The detection device comprises a current collector or a voltage collector.The current collector (1-5) is electrically connected with at least two current transformers (3) or wireless collecting coils (6), a PLC controller (1-3) is electrically connected with the current collector (1-5), a display (1-2), an alarm (1-1) and a network communication module (1-4), and the network communication module is electrically connected with a background computer 5.
