In the case of charging, take the insulating arm car to the high altitude, and touch the line with both hands. A scary, but the professionals who do not stop power. On July 21, the State Grid Zhengzhou Power Supply Company organized the first 0.4 kV distribution network non -stop power operation in the province, which means that the provincial distribution network non -stop power operation achieved a breakthrough in the low voltage field.

[On -site] The staff is fully armed, and the operation is completed under the condition

At 9 am, the north side of the Jinpeng Times Community in Xinyi Road, Zhengzhou City, five non -stop power operators gathered, and a low -voltage special insulating bucket car was also prepared. On the base rod next to them, 10 kV lines are set up on the top, and the middle part is a transformer. The 10 kV voltage transformed through this transformer to become 0.4 kV into the surrounding communities.

"Today, we are going to do non -stop power operation. The main content of the operation is to install the‘ intelligent fusion terminal ’under the situation of the transformer." Said Wang Yunlong, a senior expert of State Grid Henan Electric Power Company.

(Preparation before homework)

Before carrying out non -stop power operation, the five operators were armed: they were wearing special work clothes to prevent the arc;

After the start of the power -stop operation, a staff member took the insulating arm car and rose to the low -voltage side of the transformer in the high -altitude. He carefully took out the insulation blanket to wrap it to prepare for the later period of power.

After all preparations were ready, the staff began to implement homework. After more than two hours of busy, the entry and exit line of "intelligent integration terminal" successfully connected to the transformer.

(Operation site)

"After installing the intelligent fusion terminal, it can remotely monitor the operating status of the transformer, especially in the peak period of summer electricity consumption, and can closely track various information such as current, voltage, and parking power of the transformer. Equipment abnormalities, eliminating abnormalities, and improving residents' power supply reliability. "Wang Yunlong said that although it is common to install the integrated terminal, it was previously carried out in the state of power outage. In the first time, it is the first time that the implementation of power operations on the 0.4 kV wire of the power outlet is the first time in Henan.

(Before each job, prepare carefully)

[Behind the scenes] The voltage is low but the danger is high.

As we all know, with the continuous development of my country's power industry and the iterative upgrade of scientific and technological means, non -stop power -stop operations are common, but it has been implemented online at 0.4 kV to fill the gap in Henan.

"The power distribution transformer is the" last hundred meters' to supply residents. Considering the high temperature weather, in order to prevent residents from being affected, it takes a higher -voltage non -stop power operation method. "State Grid Henan Power Company Senior expert Wang Yunlong said.

It is reported that my country's power grid structure is very rich. According to the voltage level, 1,000 kV ACs, ± 1,000 kV, ± 800 kV DC belong to the UHV line; ; 220 kV, 110 kV, and 35 kV are high -voltage lines; 10 kV and below belong to the distribution line.

"0.4 kV is 400 volts. This time the non -stop power operation on the 0.4 kV network is a low -voltage operation." Wang Yunlong said that the current highest voltage level in the world is 1100 kV, which is often said that 1.1 million volts often said Don't look at the low voltage level of this non -stop power operation, but it is also challenging and dangerous.

(Be careful)

Wang Yunlong said that the high -voltage and ultra -high -voltage lines are used for power. The equipment on the line is very large, so the operation space is also very large, and the low -voltage line electrical equipment is densely arranged, and the operation space is very limited.

"The development of non -stop power operations at the 0.4 kV distribution network means that our non -stop power operation has officially extended to the power consumption terminal, allowing our power supply services to go closer to users, and provided the province's promotion of low -voltage non -stop power operation operations in the province. Performance experience. "Said Wang Jianxin, senior expert of State Grid Henan Electric Power Company. (Before the job, use the insulating blanket to wrap the equipment for protection)

[Future] Give the distribution network non -stop power operation power to enhance the reliability of power supply

"Low -voltage networks are becoming more and more diversified. For example, many companies and families have power generation devices. The power -on -time uses can also enter the power grid. "One hundred meters", the low -voltage network is closely connected to the user, and the relationship is the most closely. Therefore, in the new situation, it is necessary to do a good job of extended services. The successful completion of the 0.4 kV distribution network is the result of the active implementation of the relevant requirements of the State Grid Corporation and the provincial company's promotion of 0.4 kV distribution network.

(Install intelligent fusion terminal)

Forewarned is forearmed, without prejudging the waste. In order to non -stop power operation this time, they configured the 0.4 kV distribution network non -stop power operation arc protective supplies, equipment and other equipment, which provided equipment conditions for the operation. In late June this year The company's technical training center jointly organized the first 0.4 kV distribution network non -stop power operation qualification training course in the province. A total of 29 people passed the assessment, becoming the first batch of 0.4 kV distribution network non -stop power operators in the province. Carrying out the talent team.

At the same time, before this non -stop power -stop operation, they also focused on training to consolidate the work skills to ensure that all personnel were proficient in all projects.

"In the next step, we will continue to promote 0.4 kV distribution network non -stop power operators to obtain evidence, continuously strengthen the power of non -stop power operating operations, and promote the transformation of the distribution network from the" power outage and maintenance 'to the' non -stop power maintenance '. Power supply reliability and promote the optimization of the business environment to enter the new level. "Said Xin Zhongliang, deputy general manager of the State Grid Zhengzhou Power Supply Company.
