1. What is "Internet + electrical intelligent maintenance"?

With the continuous expansion of the power supply area of the urban power grid, the power supply load of the line has increased rapidly. The number of connections and sections between the original 10kV power distribution lines in the city is increasing, and the line structure is becoming more and more complex. When the line with a heavy load reaches the peak of electricity consumption, the switches will automatically trip. All power supply departments often require users with large power consumption to be equipped with full-time operation staff. The staff on duty in the electrical room must be very clear about the actual operation of the unit’s distribution network and cooperate with the grid company to be familiar with the external grid. Structure, otherwise it will increase the line outage time after the switch trips.

The user-side substation belongs to the scope of low-voltage power consumption, and is generally managed by the ownership unit itself. The traditional management method is to rely on electricians on duty 24 hours a day, use manual inspections, and notify the operation and maintenance personnel to check if abnormal conditions are found. This method is inefficient. There are a lot of maintenance costs and low safety performance. Intelligent substation management projects can realize unattended and intelligent operation and maintenance of substations through the application of Internet information technology, which can not only reduce management expenses, but also improve the safety and reliability of substation operation.

Through the Internet remote monitoring platform, the electrical equipment distributed in the power distribution room of the user is monitored in real time for 24 hours, the operation information of the electrical equipment is collected and evaluated, the equipment is judged whether the equipment is in a normal state, and an alarm prompt is issued in time for abnormal conditions found. It is convenient for operation and maintenance personnel to handle in time. Provide accurate information and basic data to predict the occurrence of failures in advance, thereby reducing maintenance outage time and saving daily operation and maintenance costs.

Use the Internet and cloud services to test the connection of remote electrical switchgear maintenance. Online monitoring is the use of information technology to collect the operating signals of switch electrical equipment through Internet applications, and send them back to the control room for background monitoring. It can discover hidden operating hazards in time, notify equipment maintenance personnel of various statuses, and handle failures in time.

2. Staffing for electrical maintenance

The operation and maintenance of electrical equipment is carried out in accordance with standard operating procedures and is divided into three levels: daily duty personnel, maintenance personnel, and overhaul construction personnel. Each type of operator has a clear division of labor and cooperation, which is a hierarchical management measure to ensure the safety of personnel and equipment according to the technical characteristics of electrical equipment.
