Abstract
The utility model relates to a one station multiple point testing and controlling cathode protector of a long distance pipeline, which is mostly suitable for the corrosion protection of an underground long pipeline steel gas pipeline. An insulation joint under the ground is arranged in a tested and controlled pipeline. Spare testing contacts are arranged on the steel pipeline at the both ends of the insulation joint under the ground. The function which is realized by three cathode protection stations is achieved only through one cathode protection station, three potentiostats, three anode ground beds and three reference electrodes. The effect of the actual application is good; not only the administrator is saved, but also the precious land resource and the expensive device cost are saved. When a running device is out of order, a spare device can run in time, which ensure the cathodic protection of the steel pipeline. The utility model has the advantages of simple structure, convenient operation and maintenance and wide practicability.
Description
One, technical field
The utility model relates to long-distance pipe one station multi-spot measurement and control cathodic protector, is particularly useful for the galvanic protection of big and medium-sized cities long distance line underground petroleum Sweet natural gas steel conduit.
Two, background technology
Galvanic protection is general in the world one of the most economical effective anti-corrosion measure of steel pipe that prevents, adopts cathodic protector, and the steel pipe erosion resistance of underground gas transmission is improved greatly, and the life-span prolongs more than 50 years.West-East National Gas Transmission Project has driven the development of each city oil and gas along the line, gasification engineering.Because the gas industrial expansion brings great convenience for resident's life, has also driven the development of every industrial technology simultaneously.Preresearch estimates: general city is on urban duct is built, and urban duct main line (gas transmission line) generally reaches the 30-100 kilometer, and such distance has brought very big difficulty for the design of cathodic protector.For example: 1) at one 60 kilometers gas transmission line one cover protector only is installed, the protection effect reaches possible at short notice, and long-time running is infeasible; 2) adopt two cover cathodic protectors, be installed in pipeline two ends (two websites of first and last) and can reach the protection effect, but the problem that exists is that the galvanic protection effect of short-term operation is passable, in the long-time running, quit work in case a covering device hinders for some reason, then another set of device is difficult to implementing effective galvanic protection completely; 3) adopt three cover cathodic protectors; from the effect of galvanic protection is the most desirable, the safest, the most reliable, the most effective, but from the angle of economic benefit, because safety coefficient is excessive; cause disposable infusion of financial resources volume too big, later period maintenance, overhead charges are too high.
Three, technology contents
(1) goal of the invention
In view of the weak point of prior art, the object of the invention provides a kind of safe and reliable, and is effective, uses manpower and material resources sparingly, economical and practical long-distance pipe one station multi-spot measurement and control the moon degree protector.
(2) technical scheme
The utility model long-distance pipe one station multi-spot measurement and control cathodic protector; it comprises cathodic protection station; potentiostat; anode groundbed; permanent reference electrode, test contact and mutual wire are provided with many potentiostats, organize anode groundbed and a plurality of reference electrode more in a cathodic protection station; be provided with on by the observing and controlling long-distance pipe and bury the ground isolating joint, the two ends of burying ground isolating joint linking steel tubes are provided with standby test contact.
The utility model long-distance pipe one station multi-spot measurement and control cathodic protector is provided with on pipeline and buries the ground isolating joint, buries the middle part that the ground isolating joint is located at long-distance pipe.Many potentiostats are three in the cathodic protection station; two operations; one standby; many group anode groundbeds are three groups; two groups of operations, one group is standby, and a plurality of permanent reference electrodes are three; be located in the pipeline section that buries isolating joint both sides, ground the other connector lug that is connected with standby potentiostat that is provided with of standby test contact.
(3) technique effect,
The utility model long-distance pipe one station multi-spot measurement and control cathodic protector; be best suited for the galvanic protection of underground long distance line steel gas pipe line; in tested keyholed back plate line, be provided with and bury the ground isolating joint; bury isolating joint two ends, ground steel pipe and be provided with standby test contact; only use a cathodic protection station; three potentiostats; three groups of anode groundbeds and three reference electrodes; just can finish the function that three cathodic protection stations could realize; practice is effective; managerial personnel had both been saved; saved valuable land resources and expensive cost of equipment again, when operational outfit broke down, stand-by facilities can in time move; guarantee galvanic protection to steel pipe; it is simple in structure, and operation and maintenance is convenient, has practicality widely.
Four, description of drawings:
Accompanying drawing is that the utility model structure connects view.
Five, embodiment
Below in conjunction with accompanying drawing an embodiment of the present utility model is described further:
The utility model long-distance pipe one station multi-spot measurement and control cathodic protector; with 60～100 kilometers pipelines is example: buried ground isolating joint 2 by the setting of the pipeline 1 of 60～100 kilometers distances of observing and controlling (protected pipeline) middle part; the steel conduit that buries the connection of isolating joint 2 two ends, ground is provided with 10, two standby test contact 10 other being provided with and standby potentiostat wire joint 11 of two standby test contact.A cathodic protection station is set, 4, three permanent reference electrodes 6 of 3, three groups of anode groundbeds of three potentiostats, wherein potentiostat 2, one group of anode groundbed 4, a permanent reference electrode 6 are standby.Potentiostat 3 is selected the PS-1 type for use, and anode groundbed 4 is rearranged by many high silicon cast iron Kun lines, and permanent reference electrode 6 is the black electrical conductor of insoluble stone.Anode line 5 links together anode groundbed 4 and potentiostat 3, and cathode rays 8 is connected with potentiostat 3 with ground wire (zero-bit scoops out line) 9 one ends, and an end is connected with test contact on the protected pipeline 1.Permanent reference electrode wire 7 links together permanent reference electrode 6 with potentiostat 3, routinely can apart from respectively positioning instant being set.When being a problem appears in the pipeline cathode protection that buries ground isolating joint 2 duct couplings 1 any end; perhaps two ends go wrong simultaneously; when quitting work; edge-only promptly reinstate standby potentiostat 3; standby group of sun level groundbed 4 and standby permanent reference electrode 6; one or two standby contacts 10 that bury on the ground isolating joint 2 two ends pipelines will be located at; be connected with standby potentiostat wire joint 11; by standby potentiostat 3; standby sun level groundbed 4 and 6 work of permanent reference electrode; make pipeline work completely not out of service, guarantee galvanic protection steel pipe.
