工频介电常数及介质损耗测试仪产品概述:(The frequency of dielectric constant and dielectric loss tester overview of products:)主要用于测量高压工业绝缘材料的介质损失角的正切值及电容量。主要可以测量电容器、互感器、变压器、绝缘纸、电容器薄膜等各种电工油及各种固体绝缘材料在工频高压下的介质损耗(tgδ)和电容量( Cx),其测量线路采用“正接法”即测量对地绝缘的试品。由于电桥内附有一个2500KV的高压电源及一台高压标准电容器,并将副桥和检流计与高压电桥有机的结合在一起,特别适应测量各类绝缘油和绝缘材料的介损(tgδ)及介电常数(ε)。
(Mainly used for dielectric loss measurement of high pressure industrial tangent insulating material angle value and capacitance. The main measurement of capacitor, transformer, transformer, insulation paper, capacitor film and other electrical oil and all kinds of solid electrical insulating materials at power frequency high voltage of the dielectric loss (TG delta) and capacitance (Cx), the measuring circuit adopts "positive connection method" is the measurement of insulation test. Because of high voltage power supply bridge with a 2500KV and a high voltage standard capacitor, and the vice bridge and galvanometer and high voltage bridge together, especially suitable for the measurement of dielectric loss of insulating oil and insulation materials (TG delta) and Permittivity (epsilon).)
