Background technology
Along with electrolysis of aluminum enterprise production line development, series voltage improves constantly, high pressure reaches more than the 1500VDC, originally adopt two voltmeters of serial controlling board installing to judge cell insulation whether good (whether ground connection), difficulties: first voltage is high, high pressure is introduced controlling board watch-keeping cubicle, controlling board are worked the mischief, therefore do not allow to introduce high pressure; Two to be that insulation detects not directly perceived for it, and the operator can only carry out artificial judgment by the displayed value of voltmeter, nor can send into rectifier supervisory system (SCADA) system, can not show intuitively the electrolyzer earthing position.
Summary of the invention
The technical problem to be solved in the present invention: a kind of cell insulation proofing unit is provided
To solve: current employing is judged whether good entering the watch-keeping cubicle such as high pressure and causing watch-keeping cubicle and controlling board harm of being brought of cell insulation at controlling board installing voltmeter, detection needs artificial judgment not directly perceived, with voltmeter detect information can not with the problem such as supervisory system networking.
Technical solution of the present invention:
A kind of cell insulation proofing unit, it comprises positive electrode bus, negative pole bus and electrolyzer, positive electrode bus is by the first high-tension fuse access voltage shielded box, the negative pole bus is by the second high-tension fuse access voltage shielded box, positive electrode bus and ground wire in the first voltage isolator input termination voltage shielded box, negative pole bus and ground wire in the second voltage shield retaining input termination voltage shielded box, positive electrode bus and negative pole bus in the tertiary voltage shield retaining input termination voltage shielded box, the output terminal of three voltage isolators is received respectively the analog quantity input of intelligent control unit, and intelligent control unit is received supervisory system with communication cable.
High-tension fuse device one, the second high-tension fuse, the first voltage isolator, second voltage shield retaining and tertiary voltage shield retaining are installed in the voltage shielded box.
Beneficial effect of the present invention:
The present invention accesses the voltage shielded box by two high-tension fuses with dc bus, and the voltage shielded box is installed in by the rectifier bus, has realized with high-pressure limit at the scene, has solved high pressure and has entered the problem that watch-keeping cubicle and controlling board harm are caused in the watch-keeping cubicle; Measure respectively anodal voltage to ground with three voltage isolators, negative pole voltage to ground and series voltage Vpe, Vne, Vpn, by voltage isolator high pressure is become the 4-20mA current signal, signal is sent into the analog quantity input of intelligent control unit, utilize intelligent control unit to record, process the magnitude of voltage of detection, show earthing position and alarm message, solved with voltmeter directly by problems such as artificial judgment are not directly perceived; Intelligent control unit is connected to supervisory system (SCADA) by communication cable, and supervisory system gathers related data and carries out centralized supervisory control.Solved with voltmeter detect information of voltage can not with the problem such as supervisory system networking.
