Filed: 1991-01-31
Abstract: PURPOSE:To prevent a water leak by detecting the corrosion of a joint fitting at an early stage by providing a gold electrode to the leading end part of the joint fitting becoming a positive side in an insulating joint for DC high voltage machinery and measuring the potential change of the joint fitting. CONSTITUTION:Since a joint metal fitting 1 is usually formed using a highly corrosion-resistant metal such as stainless steel hard to corrode, the presence of the corrosion of the fitting 1 can be judged by monitoring the potential of the fitting 1. A gold electrode 5 and a potential difference measuring device E detect the potential of the fitting 1. A frequency analyser 4 converts the detected potential change to a spectrum easily judged by a corrosion judging device CPU and the device CPU automatically judges the presence of corrosion on the basis of the spectrum. By this constitution, the corrosion of the joint fitting 1 is detected at an early stage to prevent a water leak.
