The intermediate links connecting power plants and users, such as transmission and distribution lines and substations, are part of the power system and are called power networks. The power network is often divided into two parts: the transmission network and the distribution network. The network consisting of 35kV and above transmission lines and the substations connected to them is called the transmission network. The role of the transmission grid is to transmit electricity to various regions or directly to large users. The line below 35kV directly supplying power to the user is called the distribution network or distribution line. If the user voltage level is 380V/220V, it is called low voltage distribution line. The user transformer with a voltage drop of 380V/220V is called the user distribution transformer. If the user is a high-voltage electrical equipment, the power supply line at this time is called a high-voltage distribution line. The line connecting the user distribution transformer and its pre-substation is also called the high-voltage distribution line.

In the power distribution room of the school, the team members carefully checked the operation status of transformers, high-voltage switchgear and other equipment and the operation of protection devices, carried out infrared temperature measurement on the equipment in operation, carried out key inspection on English listening and broadcasting electrical equipment, and carried out pre-test on the standby power supply to ensure that the power supply was safe.

On the morning of the 30th, at the examination center for the college entrance examination, Xiang Bao's power personnel came to the school power distribution room. according to this, together with the electrician on duty, they sorted out and investigated the operation of the school power distribution room's equipment, the distribution of internal important loads and the configuration of self-provided emergency power supply. they also carried out infrared temperature measurement and detection on the power distribution equipment to comprehensively investigate the hidden dangers of safe power supply during the college entrance examination.

During the snowfall, closely follow the weather changes and implement various power supply guarantee measures in accordance with the principles. In the cold wind, the security personnel will step up their inspection and care of power facilities such as substations, power distribution rooms, transmission lines, etc., timely investigate and control all kinds of environmental hidden dangers, and continue to do a good job in differentiated operation and maintenance such as heating equipment operation monitoring and infrared temperature measurement. In addition, in areas prone to icing, deicing personnel and ice melting vehicles are on standby at any time. The personnel on duty at 19 ice observation points and 24 ice observation posts carry out real-time icing observation, test important meteorological parameters such as wind speed, temperature and humidity, and timely grasp the operation status of the line.

Jining Power Supply Company visited key customers of power protection in advance, grasped the electricity demand of customers in time, carried out comprehensive and detailed inspection on the switching of customers' backup power supply and self-provided generators, and arranged special personnel to supervise and assist customers in rectification of problems found. Organize rainbow communist party member service team to stick to the equipment site involved in power protection, carry out dynamic inspection and marking of first-class power distribution equipment such as power distribution room, ring network cabinet, line, etc., supervise and guide the power management units in important places to inspect the electrical equipment inside the activity venues, ensure the safe and stable operation of the equipment, and ensure the power supply during the activity.

With the acceleration of the construction process of the new power system, the new demand for power grid equipment is further emerging, from the ultra-high voltage supply, large power grid configuration, distribution network consumption and other aspects of force, to promote the new and shabby power grid equipment, development and transformation.

Including all equipment and materials and civil construction costs and power bureau related costs, including transportation and handling, safe and civilized construction; Ensure the acceptance of Guanhai Huafu high and low voltage power distribution project, and the transfer of residential electricity to operation and maintenance and business management. The handover scope includes: high-voltage power supply lines and equipment; high-voltage and low-voltage electrical equipment and ancillary equipment in residential stations and distribution rooms, low-voltage power supply lines, one meter box for each household, T-connection box and meter.

On the 22nd, Linxi County Power Supply Company relied on the system to comprehensively carry out the management of heavy overload and light no-load equipment for substations, main transformers, transmission and distribution lines and distribution transformers, so as to comprehensively improve the operation quality of equipment and optimize the power supply structure.

According to the experience of previous years, the electricity load of residents rose sharply during the May Day holiday, and the operating pressure of distribution network in urban areas increased. In order to do a good job in ensuring electricity during the May Day period, preparations and careful arrangements were made in advance. A week in advance to hold the May Day Power Protection Special Meeting, and formulate. According to the analysis of weak lines according to the operation of the power grid in previous years, the potential safety hazards of high and low voltage power distribution lines and power distribution facilities shall be investigated in advance, and rectification plans shall be formulated in time for all kinds of potential safety hazards found and eliminated before the festival.
