The metering device is the last link in the safe production of smart grid . The operation of the metering device is not only related to the accuracy of marketing measurement , but also related to the safety of sales power management . Its safe and stable operation is a strong guarantee for the social and economic benefits of the power supply company in the corresponding city . At present , the metering device is mainly used to install lead seal and metal mechanical lock for locking protection , more keys , difficult management , the mechanical lock itself is low security level , easy to be unlocked , poor anti - theft effect , but from the form of " lock ". In addition , marketing and production operations are mainly small scattered operations , resulting in marketing and production operations to become the most prone to electric shock personal injury . The intelligent interlock captures the pain points of marketing and production operations , integrates the system with the electricity information acquisition system , combines the marketing and production work order to " authorize unlocking ", standardizes the production process of marketing operations , and realizes the whole process control of on - site operations .

Through the implementation and operation of this system , first of all , the situation of the on - site cabinet door being damaged and the power facilities being stolen can be avoided ; Secondly , it can avoid the operator opening the cabinet door by mistake when working , and reduce the risk of misoperation and straying into the live interval . In addition , in the low - voltage inspection , through the management of the main station to see the geographical line map , you can monitor the development of inspection work , and effectively implement the provincial company on the " first meter reading cycle after the meter change requires on - site check list number house number " work requirements . Finally , the system can complete the data query and management suggestions after data analysis according to different filtering conditions , and constantly improve and improve the monitoring and management level of marketing measurement .
