Description

Technical Field

[0001] This utility model relates to the intersection of electrical automation and corrosion protection, specifically an integrated intelligent cathodic protection station for regional cathodic protection. Background Technology

[0002] In the petrochemical and natural gas industries, regional cathodic protection technology is often used for corrosion protection of complex buried pipeline systems within plant areas and stations. However, due to the widespread grounding systems within plant areas and stations, and the difficulty in effectively isolating these systems from the pipelines, a significant amount of cathodic protection current is lost through the grounding system when implementing cathodic protection for buried pipelines. To achieve the desired protection effect for buried pipelines, large petrochemical plants and natural gas stations typically require multiple impressed current protection systems to be used simultaneously to provide sufficient protection current. Some petrochemical plants and natural gas stations did not implement impressed current cathodic protection during construction and did not consider the power supply system requirements when adding cathodic protection systems, resulting in a lack of suitable locations for installing potentiostats when adding cathodic protection systems.

[0003] The potentiostat is the core equipment of the impressed current cathodic protection system. Its function is to convert the AC power from the mains into DC power suitable for cathodic protection and to intelligently control the output current. When placed outdoors, the potentiostat is easily affected by harsh environmental conditions such as temperature and humidity, corrosive gases, wind, rain and dust, resulting in a high failure rate and shortened lifespan. It is also easily damaged during petrochemical maintenance and station upgrades. Furthermore, its structure and operation do not meet the explosion-proof requirements of petrochemical plants and natural gas stations.

[0004] Therefore, there is an urgent need for a cathodic protection station suitable for regional cathodic protection to ensure the safe operation of the potentiostat and to be suitable for explosion-proof areas. Utility Model Content
