Problems solved by technology

[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

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...
