化验室在使用国产JP-1型.JP-1A型.SJP-1型示波极谱仪中最常出现的故障,就是电源部分的B_4变压器短路、击穿、烧坏等现象.主要原因是由于B_4两组高压绕组,遇到阴雨天气和潮湿季节,变压器受潮绝缘性能下降而引起。我们使用的SJP-1型示波极谱仪曾多次出现这一毛病。为了解决这一问题,将B_4用双
Laboratory in the use of domestic JP-1 type. JP-1A. SJP-1 oscilloscope polarography most common failure is the power part of the B_4 transformer short circuit, breakdown, burn out and so on. The main reason is As B_4 two groups of high-voltage windings, encounter rainy weather and wet season, the transformer damp insulation caused by the decline. The SJP-1 Oscillopolaronometer we have used has seen this problem many times. In order to solve this problem, B_4 with double
