Warmly congratulate Guangdong Keyuan Electric Co., Ltd. SZ (B) 13-M-ZT-30 (10) ~ 500 (160) / 10 series of on-load capacitor-regulating power transformers through the new products and new technologies identification and acceptance!

The identification through the SZ (B) 13-M-ZT-30 (10) ~ 500 (160) / 10 series of on-load capacitor-regulating transformers is the industry's first to do new product technology identification and acceptance. Whether for the industry, or for Keyuan, have great milestone significance!

On August 12, 2023, Guangdong Keyuan Electric Co., Ltd. new products and new technology appraisal meeting was held in the office building of Keyuan Electric 1 floor conference room!

The appraisal will be led by the Guangdong Provincial Machinery Industry Association, the appraisal committee members are China Southern Power Grid Company Limited, Guangdong Power Grid Company Limited, Guangdong Power Grid Company Limited Electric Power Research Institute, South China University of Technology and other units.

The new products and new technology appraisal meeting of our company attended by Qi Zixuan, Li Tao, He Mengju, Qiu Guoxing, Li Lizin, Wu Haiou, Wang Weifeng, Lin Guijun.

Appraisal meeting, the expert judges on the independent research and development of Kewon Electric SZ (B) 13-M-ZT-30 (10) ~ 500 (160) / 10 series of on-load capacitor-regulated voltage regulator power transformer for strict identification, not only on the product's innovative points of the careful questioning, but also fully discussed the product's advanced nature and feasibility.

Its advanced design concept and rigorous technical arguments by the experts of the common praise, and unanimously agreed that the identification of new products with a high level of intelligence, good overall performance, in the domestic similar products with a certain degree of advanced, representative.

Commissioned by the appraisal committee, the performance test group inspected our production tooling and test equipment, and on-site performance sampling test on our trial SZ(B)13-M-ZT-30(10)~500(160)/10(SZ(B)13-M-ZT-400(125)/10) on-load capacitor-voltage regulator power transformer prototype.

After testing and discussion, it was agreed that the performance meets the technical conditions of the product and the requirements of the relevant standards, factory and type test items are complete, test results in line with the relevant technical standards; on-site sampling factory test items, test item results are qualified; tooling equipment and factory test equipment is complete, can meet the production needs.

SZ(B)13-M-ZT-30(10)~500(160)/10 series on-load capacitance-adjusting voltage-regulating power transformer is a full-featured intelligent distribution transformer with automatic capacitance-adjusting voltage-regulating, mainly used for 630kVA and the following distribution substations, to realize the automatic capacitance-adjusting, automatic voltage-regulating function.

The core component is the on-load tap-changer with automatic capacitance-regulation and voltage regulation, bistable permanent magnet mechanism, vacuum arc extinguishing double-break structure contacts, low loss, miniaturization and other characteristics.

It can solve the problem of voltage fluctuation commonly found among distribution network users, and at the same time solve the problem of large load differences and high losses in rural distribution areas, realizing the economic and reliable operation of distribution network areas.
