Problems solved by technology

[0004] An "insulation checker" of the kind described above requires the probes of the tester to be placed on each side of the insulation in direct contact with the structure, and cannot be inspected where the tester probes cannot be directly connected to the insulating structure. It is suitable for relatively large metal insulation structures, structures with anti-corrosion insulation layers, insulation structures buried in the soil and not exposed to the ground, etc.

Embodiment Construction

[0042] The invention provides a cathodic protection insulation tester and a test method thereof.

[0043] Such as figure 1 As shown, the tester is applied to a cathodic protection system. The system includes a protected end and a non-protected end. The protected end is provided with a protected structure, and the unprotected end is provided with a non-protected structure and a grounding body. The protected end 1. An insulating device is arranged between the non-protected ends, and the tester includes a power supply, a signal applying unit, a signal introducer, and a signal receiving unit.

[0044] The signal applying unit is used for transmitting an AC signal with a frequency of a predetermined signal. Existing AC signal transmitters can be used. It is preferable to choose between 50Hz-65KHz frequency. Since the low-frequency signal has a large wavelength, the transmission distance is long and it is not easy to radiate to other devices, the low-frequency signal is preferred....

Abstract

The invention provides a cathodic protection insulation tester and a test method thereof. The tester is applied to a cathodic protection system, the system includes a protection end and a non-protection end, the protection end is provided with a protected structure, the non-protection end is provided with an unprotected structure and a grounding body, an insulating device is arranged between the protected end and the unprotected end, and the tester includes a power source, a signal applying unit, a signal importer and a signal receiving unit. The tester has high precision, high efficiency andexcellent application value, and misjudgment is not easily generated.

Description

technical field [0001] The invention belongs to the technical field of insulation testing, in particular to a cathodic protection insulation tester and a testing method thereof. Background technique [0002] In the cathodic protection system, the electrical insulation performance of the structure is very important to whether the cathodic protection system applied is effective. In the operation of the cathodic protection system, in order to prevent it from protecting the non-protected structures in the laying environment, it should be ensured that the structural systems such as pipelines and storage tanks where the cathodic protection plays a role have good electrical insulation performance, so that they are not separated from the non-protected structures. Insulation (resistance between each other reaches megohm level or above). When the level of cathodic protection cannot be maintained within the scope of design or standard requirements, it is likely to be caused by electri...
