电瓷厂主要是生产耐高压的电瓷绝缘体。为满足产品质量筛选要求,产品出厂前必须在高电压试验间进行耐压性能的试验和检测。被试验的成批电瓷产品在通过高电压试验区域时,会迸发出强烈刺耳的“噼噼拍拍”高强噪声,可达114分贝(A)左右,有时甚至更高。因此,电瓷厂高压放电试验间的噪声治理,成为各方日益重视的治理课题。 Electric porcelain factory mainly produces high voltage ceramic insulator. In order to meet the requirements of product quality screening, the products must be tested and tested for the withstand voltage performance before leaving the factory. The bulk electric porcelain to be tested passes a high voltage test area and emits a strong, harsh “snap shot” high-intensity noise of around 114 decibels (A), sometimes even higher. Therefore, electric porcelain high pressure discharge test between the noise control has become an increasingly important issue of governance.
