According to "Product Quality Law of the People's Republic of China" and "product quality supervision and spot checks management approach," the provisions of AQSIQ on domestic production of consumer goods, building decoration materials, food, agricultural means of production, industrial production, 26 categories Product quality of the national supervision and spot checks, the results will now be announced.
A total of 58 enterprises in 17 provinces and municipalities, including Beijing, Tianjin, Hebei, Shanxi, Shanghai, Jiangsu, Zhejiang, Anhui, Jiangxi, Shandong, Henan, Hubei, Hunan, Guangdong, Chongqing, Sichuan and Shaanxi, Power transformer products.
The spot checks based on "Power Transformer Part 1 General" GB1094.1-1996, "Power Transformers Part 11: dry-type transformers" GB1094.11-2007, "three-phase distribution transformers energy efficiency limit value and the value of energy-saving evaluation" GB20052 And other standard requirements, the power transformer winding insulation resistance, winding resistance measurement, the voltage ratio measurement and connection group label test, short circuit impedance and load loss measurement, no-load current and no-load loss measurement, Pressure test, induction voltage test, temperature rise test, partial discharge measurement, insulation oil test (breakdown voltage) and other 10 items were tested.
Spot checks found that 14 kinds of products do not meet the requirements of the standard, related to the temperature rise test, partial discharge measurement, external voltage withstand test, short circuit impedance and load loss measurement, no-load current and no-load loss measurement, Voltage) project.
In addition, Hunan General Transformer Manufacturing Co., Ltd. and Guangzhou dry-type Transformer Co., Ltd. 2 companies refused
