Abstract
The invention relates to a rust prevention method for an outdoor current transformer. The current transformer is soaked with an imidazoline corrosion inhibitor solution, an adsorption thin film is formed on the surface of the current transformer, and therefore the function of rust prevention is achieved. According to the rust prevention method, electric conductivity and magnetic conductivity of the current transformer are not influenced, adsorption force is high, the current transformer cannot be washed away by rainwater, the rust prevention effect is good, the process is simple, and operation is easy.
Description
Technical field
The present invention relates to the technical field of rust prevention of device of outdoor electrical equipment, specifically one imidazoline inhibitor
Prevent the current transformer on outdoor high-voltage line from getting rusty.
Background technology
Current transformer on outdoor high-voltage line, the most exposed in atmosphere, by weather and the shadow of variations in temperature
Ringing and get rusty easily, and equipment needs high permeability, once seam gets rusty, and permeability can decline to a great extent, shadow
Ring and use.Owing to being under high-altitude, high voltage environment not easy-maintaining, thus current transformer is antirust becomes one
Individual critically important problem.The antirust paint painted has certain thickness, understands conduction and the permeability of jamming equipment,
Affect the normal use of equipment, thus antirust paint can not be painted.The rust-proofing method used at present is that installation is external
Protecting box, smears protection oil, prepares transformer etc. with high-quality anti-rust metal material.External guarantor is wherein installed
Protect box not only to bother, and have an impact high-tension line is properly functioning；Smearing protection oil can only be at short notice
Protection equipment；Being prepared transformer by high-quality anti-rust metal material, its effect is more excellent, has good antirust
Effect, but cost is high.
Imidazoline inhibitor is a widely used corrosion inhibiter of class, has low toxicity non-stimulated, and biological degradability is high,
Environmental protection, the features such as heat-resistant stability is good, and rust inhibition is excellent, CO can be prevented by blanketing effect2To metal
Corrosion, have excellent corrosion inhibition, be widely used in oil, natural gas extraction and transport.Due to miaow
Oxazoline corrosion inhibiter is one layer of very thin film metal surface absorption formation, does not interferes with its conduction and magnetic conduction
Rate, can be used on device of outdoor electrical equipment.
Summary of the invention
It is an object of the invention to overcome the deficiency of current transformer rust-proofing method on above-mentioned existing high-voltage line, carry
For the antirust new method of current transformer a kind of simple to operation, that rust-proof effect is good.
The realization of the object of the invention, comprises the steps:
(1) current transformer is soaked with imidazoline inhibitor；
(2), after soaking absorption, Outdoor Current Transformer is taken out, dries or dry.
In described step (1), imidazoline inhibitor can use solvent furnishing finite concentration as required.
Described step (1) soaking temperature is 0～120 DEG C.
Described step (1) soak time is 0.5～2 day.
In described step (1), in order to improve adsorption effect, soak can be allowed to flow.
In described step (2), the current transformer soaking imidazoline inhibitor dries or dries, and works as table
Just can use when face without humidity or is not glued.
Beneficial effect: rust-proofing method of the present invention is to delay at one layer of imidazoline of current transformer surface adsorption
Erosion agent film, does not interferes with its conduction and permeability, and will not be washed away by rainwater, favorable rust preventing effect, work
Skill is succinct, simple to operate.
Specific implementation method
Illustrative and be further appreciated by the application below in conjunction with specific embodiment, but embodiment is only

Existing rust spot on current transformer, and soaked there is no rust spot.
Embodiment 2
In 1000mL beaker, by 203.81g oleic imidazolinone 800mL xylene soluble, in temperature
It it is immersion current transformer in about 50 DEG C environment.Every 1-2 hour, take out transformer, after agitation solution
Continue to soak, take out after 8 hours and dry.Two current transformers that will soak with corrosion inhibiter and do not soaked
The hydrochloric acid mist test of 5 it is about with pH, after 24 hours, it was observed that the electricity not soaked under similarity condition
Existing a large amount of rust spots on current transformer, and only 6 rust spots soaked.
Embodiment 3
In 1000mL beaker, by 85.45g oleic imidazolinone 400mL xylene soluble, it it is 60 DEG C in temperature
Left and right environment soaks current transformer.Every 1-2 hour, take out transformer, continue to soak after agitation solution,
Take out after 10 hours and dry.By two current transformers soaking with corrosion inhibiter and do not soaked at same batten
The hydrochloric acid mist test of 5 it is about with pH, after 38 hours, it was observed that the current transformer not soaked under part
Entirety is got rusty, and the only several rust spots soaked.
