Title: Partial discharge detecting method for power cable line
Inventor: MABUCHI TOSHIAKI
IPC: G01N21/3563
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To specify generation of partial discharge on a power cable line and the generated part position by detecting acetylene or ethylene contained in the constituting member of the power cable line, and detecting the concentration distribution. SOLUTION: A power cable line is electrified to confirm generation of partial discharge by electrical measurement, and the power cable or the connection part of part position estimated to generate partial discharge is dismembered. Next, samples are picked up from the respective part positions of respective constituting members of the dismembered part. Acetylene or ethylene fused in a small piece is expelled from the small piece and collected. This gas-like acetylene or ethylene is qualitatively and quantitatively analysed by an analyser such as a gas chromatograph, an infrared spectroscopic device, or a mass spectrometer. When acetylene or ethylene is detected by the analysis, it can be confirmed that partial discharge is generated on the part position of the constituting member, and the generated part position is also decided.

Abstract: PURPOSE:To eliminate overshoot when heating with a heater and to execute a stable temperature control, by applying high voltage to a heater provided on a lamp at the time of a reference temperature or below, and switching it to low voltage at the time of reference temperature or above. CONSTITUTION:Immediately after an electric power source is turned on, or under low temperature environment, high voltage V1 is supplied to a heater 2 through a relay contact PL1, therefore, a lamp tube wall temperature rises quickly. Subseqently, when the tube wall temperature reaches a prescribed value, a thermostat contact THS2 is closed and a relay coil RLC is energized. As a result, a relay contact PL2 is closed, and low voltage V2 is applied to the heater 2, therefore, a rise of the tube wall temperature becomes gentle and overshoot becomes small. Thereafter, the heater 2 is subjected to a temperature control by opening and closing of a thermostat contact THS1. In this way, overshoot in case of heating by a heater is eliminated and a stable temperature control can be executed.
