1, what is the "Internet + electrical intelligent maintenance"?

With the urban power supply area continues to expand, the line power supply load grows rapidly. The city's existing 10kV distribution lines in the middle of the contact and segment increasing, more and more complex circuit structure, usually overload the load line to reach the peak, the switch will automatically trip. All power supply departments often require large users to be equipped with full-time operation of the duty officer, the user is equipped with the electricity on duty staff is to be very clear the actual operation of the unit distribution network, but also with the grid company familiar with the external grid Structure, otherwise it will increase the line after the switch trip power outage time.

User-side substation is a low-voltage electricity range, generally managed by the ownership of their own units, the traditional management approach is to rely on electrical 24-hour duty, with artificial to stare at the inspection, found abnormal situation will inform the maintenance personnel maintenance, this method inefficient Conservative cost a lot, security is not high. Substation intelligent management project through the application of Internet information technology can achieve substation unattended and intelligent operation and maintenance, which can reduce the cost of management fees, but also improve the safety and reliability of substation operation.

2, electrical maintenance staff equipped



Electrical equipment operation and maintenance in accordance with the standard operating procedures, divided into three levels, daily duty personnel, maintenance personnel, maintenance personnel. Each type of operator has a clear division of labor relations, is based on the technical characteristics of electrical equipment to ensure that personal and equipment safety management of the hierarchical management measures.

3, maintenance staff duties

Daily duty officer duties:

(1) the emergency treatment requirements for abnormal conditions; (2) the sequence of shutdown operations; (3) the operation of the emergency operation; (4) the order of operation; (5) the operation of the operation and inspection and confirmation; (6) the operating point of use of the equipment should pay attention to the source, safety or safety requirements should be implemented.
 Maintenance personnel duties: equipment maintenance procedures to be carried out under the supervision of supervisors. (1) equipment hygiene standards; (2) lubrication "five" requirements; (3) inspection routes, parts, methods, content (4) maintenance of the equipment, maintenance, (5) downtime equipment maintenance; (6) equipment defects, hidden dangers, fault handling requirements; (7) maintenance records requirements. (8) equipment defects, hidden dangers, fault handling requirements; (8) maintenance records requirements; (9) regular testing, adjustment, security requirements;

Maintenance of construction workers duties; construction unit personnel and qualification examination, maintenance plan approval implementation, power cycle to inform. (1) the maintenance program to implement the contents; (2) maintenance sequence process; (3) spare parts replacement and maintenance process requirements; (4) quality acceptance technology (5) maintenance cycle of the record; (6) maintenance personnel to determine the responsibility of the program; Standard; (7) test acceptance; (8) maintenance records for the record.

4, intelligent maintenance advantages

The special nature of the operation and maintenance of electrical equipment makes the operation and maintenance costs of the power users long and high. With the gradual opening of the electricity market, the independent and closed operation and maintenance system is facing the severe impact, more open, flexible and resource-optimized social maintenance Collaborative ecological, Internet maintenance service system to protect the trend of change significantly. (Including maintenance personnel, maintenance technology and advanced maintenance equipment and other equipment, etc.) in a wider range of sharing, effectively reduce costs and improve the quality and efficiency of operation and maintenance, the industry are exploring new development routes The

The core technology of online monitoring is to use high-voltage switchgear and transformer power electrical components, through computer network technology and modern communication technology used in the user high and low voltage distribution room remote maintenance business, to enhance the maintenance of service quality, improve equipment operation Reliability and efficiency.




The specific operation plan is through the establishment of intelligent distribution remote monitoring platform, the distribution room information, signals, and operational data through the communication device remote transmission to the central monitoring room, the central control room on the service network to implement all the power distribution room remote , Centralized monitoring, to ensure that the distribution room even in unattended state can also be in a safe state, the other for fault, maintenance and other issues, the platform can provide 24-hour equipment to run the alarm service.

5, the Internet + intelligent operation and maintenance market size



Any large and medium-sized cities will have more than 20,000 10KV user-side substation, these substations are mainly residential, social public institutions, schools, hospitals, factories and mines, large shopping malls, commercial buildings in use. According to a substation 50,000 yuan technical conversion fee calculation, the initial estimate is more than one trillion the size of the market.
