At present, the field operation metering device is usually protected by adopting a technical measure of applying a seal, namely, a sealable cover plate or a box is arranged on an operation part of the metering device, a special seal is arranged at a switch, the seal can not be reused once being disassembled, but the seal is relatively simple in structure and lacks necessary anti-counterfeiting measures, in recent years, the potential hazards of electricity stealing/illegal electricity utilization and safety hazards caused by unauthorized operation of the metering device appear to be increased, the traditional seal is difficult to fundamentally forbid illegal operation and lacks effective alarm function, discovery and check of related events are often delayed, great difficulty is brought to evidence obtaining, rectification and check, and good protection measures are difficult to obtain for the problems of electricity stealing, illegal operation, unauthorized operation, especially the technical electricity stealing and the like which are gradually raised at present in long-term work, so that a plurality of problems exist, the details are as follows:

in the recent technical electricity stealing cases, the situation that electricity is stolen by adopting a mode of imitating and forging seals presents a high situation, and the existing technical measures and means lack the protection effect on the operation.

From the aspect of a protection implementation mode, the interception and the negation of violation and unauthorized operation are difficult to realize by the currently adopted management and control means, on one hand, in the scene of electricity stealing, the validity of electricity stealing operation is continued until electricity stealing is discovered, which brings inconvenience to the compensation of error electricity quantity and the punishment of electricity stealing and default electricity utilization behaviors and also seriously influences the operation performance of the metering device; on the other hand, to

The misoperation of staff lacks the protective capacities, because seal and the tool to lock that use are normal equipment under this scene, will make the effect duration of maloperation longer, and the influence is more serious.

From the view of a discovery and control mechanism, the control means of the currently adopted running electric energy metering device lacks active warning and prompting capabilities, and the time from illegal and unauthorized operations to discovery is usually unequal to weeks, months and even years, so that adverse factors are caused for anti-theft and illegal electric quantity compensation, the site damage is serious during electricity stealing and illegal unauthorized operation investigation, clues or fixed evidences are difficult to discover, and the technical problems are solved.
