国家质量监督检验检疫总局近期对固定式电气装置开关(简称墙壁开关)进行了监督抽查,抽样合格率为85.4%。本次主要抽查了浙江、广东、江苏、北京、上海等5个省(市)的41家企业的41种产品,合格35种。抽查结果表明,该行业中生产规模较大的企业产品质量较好,而一些小型企业的产品质量问题较多。抽查中反映出的主要质量问题有爬电距离、电气间隙不合格,易引起电弧,造成起火;绝缘材料耐热、耐燃试验不合格,一旦使用,极易引起火灾事故。造成产品质量不合格的主要原因是:产品在设计、生产过程中未能严格执行国家标准:部分企业的产品生产工艺不过关;少数企业技术力量薄弱、偷工减料。
The General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China recently conducted supervision and random inspections of switches for fixed electrical devices (wall switches), and the sampling pass rate was 85.4%. This time, 41 samples of 41 companies in five provinces (municipalities) including Zhejiang, Guangdong, Jiangsu, Beijing, and Shanghai were selected, and 35 were qualified. The results of random inspections indicate that the products of large-scale production enterprises in this industry are of good quality, while some small-scale enterprises have more product quality problems. The main quality problems reflected in spot checks are creepage distances, unacceptable clearances, easy to cause arcs, and fires; heat-resistant and flame-retardant tests of insulation materials are unqualified. Once used, fire accidents can easily occur. The main reasons for the unqualified product quality are: The product fails to strictly enforce the national standards in the process of designing and producing: Part of the company’s product production process is not enough; a small number of companies have weak technical strength and cut corners.
