Haihong 110kV 3D wound core transformer successfully closed at one time

On October 29, 2019, good news came from Baihe Town, Kaiping City. The 110kV main transformer and power transmission of the domestic waste incineration power plant of the first phase of the first phase of the Kaiping Solid Waste Comprehensive Treatment Center project was successfully completed at one time, and it was connected to the grid. This project is included in the 2016-2020 Guangdong Province 2016-2020 Domestic Waste Incineration Power Plant Reserve Project List in the "12th Five-Year Plan for the Construction of Domestic Waste Harmless Treatment Facilities in Guangdong Province". The company won the bid, with an overall investment of about 530 million yuan. It is planned to be completed and put into use in 2020. It can handle 900 tons of domestic waste per day, which can effectively solve the problem of local domestic waste disposal. It has good economic and social benefits and is in line with the national strategy of ecological civilization construction. need.

The successful power transmission of the 110kV main transformer marks the phased victory of the project construction and lays a good foundation for the smooth operation of the project. The 110kV main transformer of this project adopts the 110kV/31500kVA three-dimensional wound core power transformer developed by Haihong Electric Co., Ltd. The no-load loss, load loss, no-load current, noise, partial discharge and other performance indicators of this product are all better than the national standard. In 2018, it passed the appraisal of scientific and technological achievements jointly organized by Guangdong Mechanical Engineering Society and Guangdong Machinery Industry Association. The appraisal committee agreed that: the comprehensive technology of this achievement has reached the international advanced level, and its noise, loss and other indicators are at the international leading level.

According to experts, the three-dimensional wound core transformer used in this project is mainly based on two considerations. First, the three-dimensional wound core transformer has the advantages of energy saving and material saving compared with the traditional planar core transformer. It meets the requirements of national green development and protects the environment with waste incineration power generation. The original intention is consistent; second, after calculation, the three-dimensional wound core transformer is used to save the operation loss of the transformer itself, which helps to improve the conversion efficiency and increase the power generation. Therefore, in terms of comprehensive social and economic benefits, the three-dimensional wound core transformer has obvious advantages compared with other products.

The success of the world's first 110kV three-dimensional wound core main transformer and power transmission has once again proved the advancement and reliability of the three-dimensional wound core technology, as well as the feasibility of applying the three-dimensional wound core technology to high-voltage and large-capacity fields. The success of this power transmission has given Haihong people greater confidence and strength. Haihong people will take this as a new starting point, continue to specialize and refine in the 110kV field, and continue to cultivate deeply to contribute to the transformer industry in China and the world Haihong wisdom, Haihong plan, Haihong power!
