Description
Technical Field
[0001] The utility model belongs to the technical field of current shunting and regulating balance of combined cathode protection of storage tanks, and specifically relates to a device for realizing current shunting and regulating balance of combined cathode protection of storage tanks. Background Art
[0002] Since the 21st century, the national economy has developed rapidly, energy production and storage and transportation have increased exponentially, and my country's oil storage tank construction has also entered a period of explosive growth. Based on the flammable and explosive characteristics of oil (finished oil and crude oil), the protection of oil storage tanks has received great attention from industry authorities, construction units, design units and construction units. The outer wall of the tank bottom plate has been in contact with ionized water and oxygen for a long time, and the corrosion environment is special. The risk of corrosion damage is also greater than other parts. The corresponding cathodic protection technology has also been pushed to the forefront and has been widely used. Compared with large storage tanks with one tank and one protection, tanks with smaller capacity (especially those with a bottom plate diameter of less than 30 meters) generally require the use of combined cathodic protection technology for protection. In the actual operation process, due to the different environments of each tank, the resistance of each branch loop is also different, and the current output of each branch loop in the combined cathodic protection is also different, resulting in uneven cathodic protection effects of each tank: a tank in the combined cathodic protection system is over-protected due to the unexpected current; while other tanks are in an under-protected state due to insufficient cathodic protection current.
[0003] In view of this, the present utility model is proposed. Utility Model Content
