〔発明の技術分野〕
この発明は、連続電気めっき処理装置などの電解槽の絶
縁抵抗測定装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an insulation resistance measuring device for an electrolytic cell such as a continuous electroplating processing device.
・〔従来技術とその問題点〕
連続電気めっき処理装置などの電解槽に絶縁不良がある
と、絶縁不良に起因する電解電流の変動によって被処理
材の鋼板に処理むらが発生する。- [Prior art and its problems] If there is an insulation defect in an electrolytic bath such as a continuous electroplating processing device, processing unevenness will occur on the steel plate to be treated due to fluctuations in the electrolytic current caused by the insulation defect.
従って、電解槽の絶縁不良を未然に発見して、予め処置
しておくことが重要である。このようなことかメチスタ
ーを用いて電解槽の絶縁不良を測定することが行なわれ
ていた。Therefore, it is important to discover insulation defects in the electrolytic cell before they occur and take appropriate measures in advance. For this reason, Methystar was used to measure insulation defects in electrolytic cells.
しかしながら、電解槽の廻９の電気回路は複雑につなが
っているため、テスタで電解槽各槽の絶縁抵抗を測定し
ても、電解槽各槽の廻シの電気回路全体の絶縁抵抗を測
定してしまうことになり、絶縁不良箇所が正確に判らな
い。However, since the electric circuit around the electrolytic cell 9 is connected in a complicated manner, even if you measure the insulation resistance of each electrolytic cell with a tester, it will not measure the insulation resistance of the entire electric circuit around each electrolytic cell. Therefore, the location of the insulation failure cannot be accurately determined.
そこで、電解槽各槽のコンダクタロールと対地間、アノ
ードと鉄皮間および鉄皮と対地間の絶縁抵抗を測定して
、電解槽各槽の絶縁抵抗を等価回路的に評価してやれば
、電解槽各槽の絶縁不良を正確に知ることができるが、
電解槽の各部位の絶縁抵抗を電解槽各槽の全てについて
テスタで測定することは、多大な労力を要し、実用上不
可能である。Therefore, if you measure the insulation resistance between the conductor roll and the ground, between the anode and the steel shell, and between the steel shell and the ground of each electrolytic cell, and evaluate the insulation resistance of each electrolytic cell in terms of an equivalent circuit, the electrolytic cell It is possible to accurately know the insulation failure of each tank, but
Measuring the insulation resistance of each part of the electrolytic cell using a tester requires a great deal of effort and is practically impossible.
仮に測定できたとしても、絶縁不良を生じている箇所で
は例えば数１０Ωといった小さな絶縁抵抗を測定するこ
とになるので、テスタでは正確に測定することが困離で
ある。特に、アノードと鉄皮間の絶縁抵抗は、過電圧の
ある電解液を通して測定するので、正確な絶縁抵抗値を
得ることは全く不可能である。Even if it were possible to measure it, it would be a small insulation resistance of several tens of ohms, for example, at a location where insulation failure has occurred, so it would be difficult to measure accurately with a tester. In particular, since the insulation resistance between the anode and the iron skin is measured through an electrolyte with an overvoltage, it is completely impossible to obtain an accurate insulation resistance value.
〔発明の目的〕

る。[Purpose of the Invention] In view of the above-mentioned current situation, the present invention has been made to evaluate the insulation resistance of various electrolytic phases in an equivalent circuit to find out the insulation failure of each electrolytic cell, and to evaluate the surroundings of each electrolytic cell used for this purpose. It is an object of the present invention to provide an insulation resistance measuring device for an electrolytic cell that can easily and accurately measure all types of insulation resistance including electric circuits.
