On November 18, Baobian Electric Baoling's first SQPZ-50000/132TH SF6 gas insulated transformer developed for CLP Power Hong Kong successfully passed the factory test. The test results all met the requirements of the agreement and the trial production was successful.
This is the first time that a domestic gas-insulated transformer has been selected in Hong Kong. At the same time, this transformer is quite different from the previous SF6 gas-insulated transformer. It has high performance parameters, large impedance, low noise, complex appearance and structure. There are special requirements in various aspects such as the safety and environmental certification standards and operating habits in Hong Kong. The noise requirement is 52dB, the design is difficult, and the details are required. Faced with unconventional and new products, Baoling established a special R&D team in time to coordinate and conduct special R&D to ensure the smooth progress of R&D.
Because it is the first time to select a domestic gas insulated transformer, Hong Kong users have very strict confirmation of the preliminary drawings. The selection of each component and the determination of each technical parameter must be repeatedly demonstrated. At the same time, many new requirements outside the agreement have been added. With a high sense of responsibility, the designers in charge bravely shoulder heavy burdens, overcome difficulties, and give full play to the spirit of bold innovation, constantly trying, careful argumentation, and repeated revisions. Each different plan must be repeatedly considered for the advantages and disadvantages; each subtle Improvement must go through all aspects of consideration. Design and R&D personnel have actively communicated with users many times and explained to users patiently. The final design plan has been 100% approved by users.
Before each process enters the production, the technical department and quality assurance department personnel will make technical clarifications to the operator in advance, and carefully explain the differences between this transformer and the previous SF6 gas insulated transformers and what details should be paid attention to during the production process. The Quality Assurance Department prepares a quality control plan and conducts on-site supervision of the production of key components, air boxes, structural parts, stays, etc. When there is a problem in the production process, the technical department and quality assurance department personnel will be on call to discuss the problem-solving plan in time to ensure that the problem does not stay overnight. In the process of product production, the personnel of the Quality Assurance Department of Baoling Company give full play to their quality management functions, strictly control product quality, especially process control, and organize joint inspections many times to accurately grasp each quality control point to ensure products to the utmost extent. quality.
The first pass of the Hong Kong CLP Power’s gas-insulated transformer indicates that Baoling’s independent design and innovation capabilities and production capabilities have reached a new level. It is of great significance for the company to further expand the gas insulated transformer market, enhance its core competitiveness, and increase the company's reputation.
Baoling company has many years of gas insulated transformer production experience, mature and stable production technology, has been favored by users. Since the company began to produce gas insulated transformers in 2005, it has provided dozens of products for large cities such as Beijing, Shanghai, Shenzhen, etc., and these transformers are currently running smoothly on site. This product successfully passed the test and laid a solid foundation for further development of the Hong Kong market.
