On May 9th, the scorching sun in eastern Yunnan in early summer. In Zanyi District, Qujing City, the replacement of two main transformers of the 220 thousand volt Zhanyi substation is in full swing. As an important substation under the jurisdiction of Yunnan Qujing Power Supply Bureau of China Southern Power Grid, the replacement of the two main transformers is of great significance for Qujing Power Grid to meet the peak summer and consolidate the safety foundation of the west-to-east power transmission channel.
Under the strict management of safety production, the professional work of substation repair and testing of Qujing Power Supply Bureau is remarkable. Last year, the completion rate of the equipment operation plan was 100%, the completion rate of the countermeasure plan was 100%, and the equipment availability coefficient was 100%......
In Qujing Power Supply Bureau, the professional work of substation repair and testing is not only a representative, but also universal. In the context of the construction of intrinsically safe enterprises, the bureau focuses on the core of "people", improves the safety literacy of employees by linking safety with salary performance, improves the safety literacy of employees through skill output, and implements measures such as "three senses and one force" to care for employees, which effectively boosts the spirit of safety production of all employees and realizes the transformation of safety behavior from "compulsory" to "conscious".

Make up for shortcomings: find out the actual situation of safety production
"People are the core element of safety management." Talking about safety management, Zhang Cuijin, manager of the safety supervision department of Qujing Power Supply Bureau, said. In his view, safety accidents are often caused by people's unsafe behaviors and unsafe state of things, and most of the unsafe state of things are also caused by human factors. When the intrinsic safety of people is realized, various other insecurity factors will also be solved. Therefore, "to build an intrinsically safe enterprise in an all-round way, it is necessary to fundamentally solve the problem of intrinsically safe 'people'." ”
In the process of solving the problem of intrinsic safety "people", Qujing Power Supply Bureau systematically considered the awareness, ability, habits, responsibilities, guarantees and other elements of employees' safety production, and established an evaluation system for intrinsic safety personnel. At the same time, combined with the actual situation of its own "weak distribution network", it comprehensively collects and sorts out data on employees' working years, certificates, skill levels, job distribution, illegal distribution, historical violations, historical unsafe behaviors, daily safety learning, etc., and through in-depth and systematic analysis, identifies the high-incidence areas and shortcomings of employees' violations and unsafe behaviors, and then clarifies the key groups of supervision and inspection, and effectively promotes the matching of employee positions and the reasonable allocation of personnel.
While focusing on the "point" of individual employees, Qujing Power Supply Bureau has also done a lot of work in strengthening the safety management capabilities of county (district) bureaus and grassroots units. Clarify the performance rate of safety production responsibilities, the pass rate of the commissioning examination, the one-time pass rate of the safety examination, the rate of holding the special operation certificate, the proportion of zero violators, the proportion of zero AB violators, the proportion of zero party members with zero violations, the proportion of party members with zero AB violations, and other indicators, establish a "horse racing mechanism" with vertical and horizontal comparison, promote the quality control of all employees, all businesses, and the whole process, and then promote the deep integration of "organization + individual" to achieve common progress.

Improving ability: integrated management promotes the progress of all employees
In the Yuewang Power Supply Station of Qujing Malone Power Supply Bureau, Purong has won the recognition of the whole institute by relying on the real ability to manage safety.
As an expert who has served as a safety officer for many years, he has a high level of safety skills for the safety management of the power supply station, Pu Rong told the author that in addition to his own efforts, there is also an important factor, that is, the superior unit "sends education to the door".
Last year, the Party Committee of Qujing Power Supply Bureau combined with the actual situation and put forward the management concept of "five concentric and five peers" of the main distribution network, the concentric prefecture and county, the left and right associations, the cadres and the masses, and the upper and lower wins. Focusing on this concept, safety management has taken the integrated construction of safety supervision at the city and county levels as the carrier, and has made great efforts to improve the safety supervision capabilities of county (district) bureaus and grassroots teams, and has taken a series of effective measures.
In order to enhance the safety supervision force and safety production capacity of the county (district) bureau and the grassroots team, Qujing Power Supply Bureau organizes personnel from professional departments such as the safety supervision department to go down to the grassroots level every year to teach the safety management system, requirements and skills to the front-line personnel face-to-face. It should be carried out at least 10 times a year, covering all fields and links such as safety production responsibility system, safety education and training, safety hazard investigation and management, and safety tool management.
In addition to sending education to the door, the safety supervision department of Qujing Power Supply Bureau also improves the efficiency of safety supervision and safety production capacity in an all-round way through the follow-up study of grassroots safety supervisors and the cross-inspection of safety production in various counties (districts) bureaus.

Reduce the burden: Give employees the time and energy to improve their safety literacy
For Xie Yanqiong, who has worked in the substation operation position for more than 20 years, 2023 is definitely a milestone year. In this year, Qujing Power Supply Bureau developed and used digital systems such as substation production and operation support system and intelligent operation and maintenance control platform for secondary equipment, installed a total of 492 remote patrol cameras in 14 substations in the Shizong area, and included 14 substations from 35 thousand volts to 220 thousand volts into the real-time monitoring scope, and built a full-function patrol and maintenance center in the Shizong area, so that the work that originally required personnel to arrive at the scene to carry out became a remote "key" operation. During each inspection, each camera will carry out inspections according to the predetermined procedure, check the status of each part of each device one by one, and record and feedback relevant abnormalities in detail. While greatly reducing the amount of labor, it effectively improves the quality of substation operation and maintenance, and realizes the digital and intelligent transformation of the power grid.
Xie Yanqiong told me that this kind of operation saved them a lot of travel and hardships. "Some substations are located in remote locations, and each operation takes more than 3 hours on the road, plus on-site work, often a whole day of operation. When the road surface is icy in winter and slippery in summer when it rains, there is a big safety hazard in terms of traffic alone. Now, we can do it while sitting in the office, which brings us great convenience. ”
It is understood that the remote operation of power grid equipment with the support of modern digital systems not only saves a lot of manpower and material resources, but also greatly improves the quality and efficiency of work.
"If a worker wants to check the condition of a certain part of a piece of equipment in a substation, they only need to enter the data into the computer, and the remote monitoring camera will quickly locate it. Many equipment parts and instruments are located above the charged body, at a height of four or five meters from the ground. In the past, even if there were hidden dangers, it was impossible to see them with the human eye alone, and even with the help of telephoto cameras, telescopes, etc., it was difficult to see every hidden danger. Now, we have installed cameras at relevant points so that even the most hidden hidden dangers have nowhere to hide. Wu Mingwei, the squad leader of the patrol center, said.
The work burden reduction brought by digitalization not only reduces the safety risk of operations, improves the efficiency of equipment inspection, but also allows employees to have more time and energy to learn business skills related to safety production, and effectively improves the safety literacy of employees.
