一种用于检测蓄电池电源装置绝缘状况的新型直流接地漏电检测器,由煤炭科学院上海研究所和无锡县整流设备厂共同研制成功,最近通过了煤炭部技术发展司组织的鉴定,取得了“产品鉴定证书”。这种型号为JL—48(96)的直流接地漏电检测器,适用于2.5吨和5吨等级的煤矿防爆特殊型蓄电池电机车。使用时,只需将该检测器安装在电机车上便于观察的部位,接入电源并使其外壳和电机车车架保持良好的电气接触,即可对电源装置的对地漏电情况自动监视。当电源装置对地等效绝缘电阻下降到规程规定值以下时,检测器的红色发光二极管发光,表示“漏电”。该检测器中个别
A new type of DC ground leakage detector used to test the insulation status of battery power supply units was successfully developed jointly by Shanghai Institute of Coal Science and Wuxi Rectifier Equipment Factory and recently passed the appraisal organized by the Ministry of Coal Technology Technology Development and obtained the “ Certificate of authenticity”. This model is the JL-48 (96) DC Earth Leakage Detector and is suitable for coal mine explosion-proof special battery electric vehicles in the grades of 2.5 and 5 tons. Use, simply install the detector in the locomotive to facilitate the observation of the site, access the power and make the shell and the motor car frame with good electrical contact, you can automatically monitor the power supply ground leakage. When the power unit equivalent to the ground insulation resistance down to regulations below the value, the detector’s red light-emitting diode light, said “leakage.” The detector is individual
