Method and apparatus for detecting insulating resistance and releasing static electricity

Abstract

The invention relates to a method for detecting an insulating resistance and releasing static electricity and a device thereof. An insulating detection point is set in each position of detected equipment which needs the insulating resistance detection; a direct current power supply is arranged outside the detected equipment; direct current with certain voltage is generated through the direct current power supply and is transported to the insulating detection point set in each position of the detected equipment which needs the insulating resistance detection; simultaneously, a voltage and current detection device is arranged in the middle of a direct current loop; the change of the direct current voltage and current of the insulating detection point set in each position of the detected equipment which needs the insulating resistance detection is detected and compared through the detection device; a monitoring device carries out voltage and current calculation to obtain the insulating resistance of the insulating point, judges whether the insulating resistance of the insulating point is normal and forewarns or warns according to the detected insulating resistance; simultaneously, according to the monitoring device, the output static voltage is determined, whether static release is needed is judged, and under the condition of needing static release, the static voltage is released for passing through a resistance network.

Description

Technical field: [0001] The invention relates to an insulation monitoring and electrostatic discharge method and device, in particular to an on-line real-time insulation monitoring method and an electrostatic discharge device for an aluminum electrolysis multifunctional unit. Background technique: [0002] At present, in order to ensure the safety of production and avoid human and machine casualties and losses caused by insulation damage, the insulation resistance of aluminum electrolytic multifunctional machines must be tested regularly during the production of aluminum electrolytic multifunctional machines. At present, when electrolytic aluminum factories use domestic aluminum electrolytic multi-functional units, the insulation resistance is detected manually, so it cannot achieve real-time, online and automatic detection of aluminum electrolytic multi-functional units during the production process, so that the insulation layer cannot be damaged in a timely manner. And bec...

Problems solved by technology

At present, when electrolytic aluminum factories use domestic aluminum electrolytic multi-functional units, the insulation resistance is detected manually, so it cannot achieve real-time, online and automatic detection of aluminum electrolytic multi-functional units during the production process, so that the insulation layer cannot be damaged in a timely manner. And because the insulation points are many and difficult to detect, it brings a huge workload and safety hazards to the maintenance workers; in addition, the existing aluminum electrolysis multi-function machine lacks the system of electrostatic discharge function, and for static electricity The artificial method of releasing the function is not easy to implement
