Insulation monitoring is not directly perceived, and operator can only carry out artificial judgment by the show value of voltmeter, nor can send into rectifier
Monitoring system (SCADA) system, it is impossible to show electrolysis bath earthing position intuitively.
Summary of the invention
The technical problem to be solved in the present invention: a kind of cell insulation detection device is provided
With solve: currently employed control dish installing voltmeter carry out judging what cell insulation was the most well brought
Causing control room and the harm of control dish as high pressure enters control room, detection needs artificial judgment not directly perceived, with voltmeter detection letter
Breath can not be with problems such as monitoring system networkings.
Technical solution of the present invention:
A kind of cell insulation detection device, it comprises positive electrode bus, negative electrode bus and electrolysis bath, and positive electrode bus is by the
One high-tension fuse accesses voltage shielded box, and negative electrode bus accesses voltage shielded box, the first voltage by the second high-tension fuse
Positive electrode bus in isolator input termination voltage shielded box and ground wire, in the second voltage isolator input termination voltage shielded box
Negative electrode bus and ground wire, tertiary voltage isolator input termination voltage shielded box in positive electrode bus and negative electrode bus, three
The outfan of voltage isolator is coupled with the analog quantity input of intelligent control unit, and intelligent control unit communication cable connects
To monitoring system.
High-tension fuse device the one, second high-tension fuse, the first voltage isolator, the second voltage isolator and tertiary voltage
Isolator is arranged in voltage shielded box.
Beneficial effects of the present invention:
Dc bus is accessed voltage shielded box by two high-tension fuses by the present invention, and voltage shielded box is arranged on whole
By stream institute bus, it is achieved that high pressure is limited at the scene, solve high pressure entrance control room and cause control room and the harm of control dish
Problem；Measure positive pole voltage-to-ground respectively with three voltage isolators, negative pole voltage-to-ground and series voltage Vpe, Vne,

Mouthful, utilize intelligent control unit to record, process the magnitude of voltage of detection, display earthing position and warning message, solve electricity consumption
Pressure table is directly by problems such as artificial judgment are the most directly perceived；Intelligent control unit is connected to monitoring system by communication cable
(SCADA), monitoring system collection related data carries out Centralized Monitoring.Solve and can not and monitor with voltmeter detection information of voltage
The problems such as systems connection.
Accompanying drawing illustrates:
Fig. 1 is elementary diagram of the present invention.
Detailed description of the invention:
A kind of cell insulation detection device, it comprises positive electrode bus 1, negative electrode bus 2 and electrolysis bath 11, positive electrode bus 1
Accessing voltage shielded box 5 by the first high-tension fuse 3, negative electrode bus 2 accesses voltage by the second high-tension fuse 4 isolates
Case 5, the first voltage isolator 6 inputs the positive electrode bus in termination voltage shielded box 5+and ground wire PE, and the second voltage isolator 7 is defeated
Entering the negative electrode bus in termination voltage shielded box 5-and ground wire PE, tertiary voltage isolator 8 inputs in termination voltage shielded box 5
Positive electrode bus+and negative electrode bus-, three voltage isolator outfans are coupled with the analog quantity input of intelligent control unit 9,
Intelligent control unit 9 communication cable receives monitoring system 10.
First high-tension fuse the 3, second high-tension fuse the 4, first voltage isolator the 6, second voltage isolator 7 and the 3rd
Voltage isolator 8 is arranged in voltage shielded box 5, and voltage shielded box 5 is arranged on by rectifier bus.
Measure positive pole voltage-to-ground respectively with three voltage isolators, negative pole voltage-to-ground and series voltage Vpe, Vne,
Vpn, when electrolysis bath is properly functioning, Vpe, Vne should keep constant, and Vpe=Vne, such as Vpe ＜ Vne, then judge positive pole side A factory
Room electrolysis bath ground connection abnormal conditions, need to process, otherwise, such as Vpe ＞ Vne, then judge that negative pole side B Factory Building electrolysis bath ground connection is different
Reason condition, needs to process, and intelligent control unit (monitor) sends alarm signal；
Earthing position is calculated as follows estimating that N1=N*Vpe/Vpn rounds, and ground connection feelings occur near A Factory Building N1 groove
Condition, wherein N is electrolytic series total run channel number；Otherwise N1=N*Vne/Vpn rounds, near B Factory Building N1 groove, there is ground connection
Situation, intelligent control unit is added up and makees form.
The high pressure of electrolysis production line is limited in working site and does not introduce control room by this patent, utilizes intelligent control single simultaneously
Unit, records, processes the voltage of detection, display earthing position and warning, transmit relevant data to rectifier SCADA system simultaneously.
