For example, the insulation thickness of the transformer can't be as high as that of the naked eye Ultra high voltage assembly workshop lead team leader Zheng Yunfei said.
In the past 2018, the annual output of TBEA transformer reached 2. 600 million KVA, ranking first in the world.
Zheng Yunfei has worked in TBEA for 15 years. From the trial production of the first 330 kV transformer to the production of 1100 kV high-voltage transformer, Zheng Yunfei has gradually grown into the technical backbone of the enterprise. When asked about the knack, he replied, "keep improving, meticulous in the wind shower, and persistent in concentration."!
On the production line of the workshop, only the machines are flying, and the workers are busy. The lead wire, assembly and air shower room go to the basic level in spring: test box Each process is in order.
"This is the 500kV transformer production project of State Grid provincial electric power company. There are three transformers in total, which will be started at the end of December 2018 and will be delivered at the end of February this year." Su Wenjun said that the project needs to complete a series of processes, such as insulation parts, coils, iron machine, spare cylinder, cutting and general assembly, with tight time and heavy tasks. Therefore, the company has organized a team of hundreds of people to fully guarantee, reverse the construction period, and even refine the project progress to hourly calculation.
"Although we should stick to the production line at this time of every year, we have enough energy to contribute to the development of enterprises, rush orders with" ingenuity "and guarantee key national energy construction projects Zheng Yunfei said. (Shi Xin)!
At the same time, there are also a number of railway traction transformer projects of China Railway and Inner Mongolia railway.
On January 26, the reporter came to the transformer plant, changed into clean tooling, put on two layers of shoe covers successively, and entered the UHV assembly workshop through the air shower room. Because the production and testing of products have strict environmental requirements, no dust and dust are allowed. The plant is sealed and shielded with special design to avoid all kinds of radiation and clutter interference, so as to ensure the accuracy of key experimental data.
"The transformer factory is in the leading position in China in the design and manufacture of railway traction transformer." Su Wenjun said with pride that the great technical difficulty of railway traction transformer lies in its ability to resist sudden short circuit. The requirements for the production of transformer internal coil and the compactness, roundness and lamination of iron core are very high, with an error of 0. Within 5mm, the air shower room, otherwise the transformer in sudden short circuit, the coil will be deformed, fault, loss can not be estimated.
With the Spring Festival approaching, the festive atmosphere is getting stronger. TBEA transformer plant is still a busy scene, the production line full power to rush orders, busy production.
