Integrated cathode protection potential measurement device and method

Abstract

The invention discloses an integrated cathode protection potential measurement device and method. The integrated cathode protection potential measurement device comprises a nature checking piece, an outage checking piece, a first sacrificial anode piece, a second sacrificial anode piece and a reference electrode which are buried under the ground and are located beside a pipeline. The nature checking piece communicates with the first sacrificial anode piece through a first wire, and the first sacrificial anode piece communicates with the second sacrificial anode piece through a second wire. Thesecond sacrificial anode piece communicates with the pipeline through a third wire, the outage checking piece communicates with the first sacrificial anode piece through a fourth wire. The first wireis provided with a first switch A1 and a first insertion hole K1, the second wire is provided with a second switch A2, and the fourth wire is provided with a third switch A3 and a second insertion hole K2. The measuring manner is simple and efficient, and the professional requirement of survey personnel is low.

Description

【Technical field】 [0001] The invention belongs to the technical field of natural gas pipeline detection, and in particular relates to an integrated cathodic protection potential measuring device and a measuring method. 【Background technique】 [0002] At present, when measuring the cathodic protection potential, it is necessary to adjust the different ranges of the multimeter and place the electric pen on 5 different points for measurement. During the measurement process, the staff needs to be very familiar with the principle of cathodic protection to obtain accurate measurements. As a result, its measurement method is relatively complicated, and the professional requirements for the measurement personnel are relatively high. [0003] Therefore, it is necessary to provide a new integrated cathodic protection potential measuring device and measuring method to solve the above problems. 【Content of invention】 [0004] One of the main purposes of the present invention is to pr...
