Title:
BURIED GAS PIPELINE MULTI-MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/062687
Kind Code:
A1
Abstract:
The present invention provides a buried gas pipeline multi-measurement device for identifying a gas pipeline among a plurality of pipelines, which are buried underground and have temporarily exposed parts, or identifying a protective potential measurement line for measuring the protective potential of the gas pipeline among a plurality of lines in a test box for measuring protective potential, or determining whether the protective potential measurement line has shorted, the device comprising both of: a current supply unit capable of supplying an on/off direct current to an exposed pipeline, which is exposed in the ground in a state in which exposed pipeline is directly connected to the gas pipeline; and an electric potential measurement unit capable of measuring the electric potential of each of the plurality of pipelines, which are buried underground and have temporarily exposed parts, or the electric potential of each of the plurality of lines in the test box for measuring protective potential, by means of the on/off direct current supplied by the current supply unit, wherein the current supply unit comprises a power source unit for generating a current and an interrupter for generating an on/off direct current by interrupting the current generated by the power source unit, and the power source unit comprises a built-in battery and/or an external battery for supplying a current. The buried gas pipeline multi-measurement device further comprises a microprocessor controller for controlling the current supply unit, the interrupter, and the power source unit.
