Description

Water-proof stain-resistant type reactor

Technical field

The utility model relates to a kind of reactor.

Background technology

Reactor is the inductive High-Voltage Electrical Appliances that are used for limiting short-circuit current, reactive power compensation and phase shift etc. in the electric power system.It can be arranged as vertically as required, level and three kinds of assembling forms of isosceles triangle.When electric power system is short-circuited, can produce the very big short circuit current of numerical value.If do not limited, keep electric equipment dynamic stability and thermally-stabilised be very the difficulty.Therefore, in order to satisfy the requirement of some circuit breaker interrupting capacity, the outlet circuit breaker place series reactor of being everlasting increases short-circuit impedance, limiting short-circuit current.

Reactor moves when air humidity is bigger, or make moist back operation of solid insulation, and the breakdown voltage value of air improves, and the dielectric strength of solid insulation descends about 10%.Under adverse weather condition, can continuous moisture film occur and flashover takes place along moist dirty surface.In addition, after core of reactor insulation is made moist, will produce very big eddy current loss, increase the iron core local pyrexia, make high and low winding temperature rise aggravation, and cause reactor winding insulation puncture short and burn.According to investigation, reactor is bigger in humidity ratio, relatively moves in the adverse circumstances, and it is serious that reactor burns phenomenon.

The utility model content

The purpose of this utility model is in order to solve above-mentioned prior art deficiency, a kind of technical scheme to be provided, and this reactor has the good electrical insulation, and water resistance is good, characteristics such as resistant sudden strain of a muscle.

The utility model water-proof stain-resistant type reactor comprises iron core, is enclosed within the coil on the iron core, and coil is fixed by the strutting piece on the upper and lower folder, it is characterized in that being coated with PRTV antifouling flush paint layer on the exposed parts of above-mentioned coil, iron core and upper and lower folder.By being coated with PRTV antifouling flush paint layer, its protection against the tide, waterproof, antifouling, insulation property improve greatly.

During concrete the use, reactor is except that binding post, and complete machine is coated with the PRTV antifouling flush paint.Usually coating layer thickness should be more than 0.4mmmm.

Above-mentioned iron core is for to be formed by the silicon steel sheet closed assembly, and the iron core outside is coated with PRTV antifouling flush paint layer.Iron core is before suit, and the iron core external spray has the PRTV antifouling flush paint, so just avoid core of reactor insulation to make moist after, produces very big eddy current loss, the insulation property of raising iron core.

Above-mentioned coil is the poured with epoxy resin coil.

The PRTV antifouling flush paint claims the electric power overlength to imitate antifouling flush paint again, and PRTV coating has hydrophobicity and the migration of hydrophobicity that is better than the RTV antifouling flush paint, has certain oil repellency and good not viscosity simultaneously.Under adverse weather condition, continuous moisture film can occur and flashover takes place along moist dirty insulator surface.Because it has migration of hydrophobicity, make the pollution layer surface also have hydrophobicity when coating PRTV coating, the pollution layer surface only has discontinuous droplet, and can not be soaked into, in flakes, makes the anti-soil of power equipment dodge performance and is greatly improved.Compare with the hydrophobic group quantity of PRTV inside, the hydrophobic group numbers of poles of Liu Shiing is few naturally, so the useful life of PRTV is very long.Compare with RTV coating, PRTV paint-based glue is in the longer service life of occurring in nature.

PRTV antifouling flush paint of the present utility model uses on reactor, increases substantially reactor external insulation pollution flashover voltage, and pollution flashover voltage can bring up to 200%, ensures the power equipment security of operation; Coating material has hydrophobicity and unique hydrophobicity migrate attribute, and promptly hydrophobicity can migrate to the pollution layer surface, does not form continuous moisture film at bad weather (rain, mist dew, drizzle) coating surface; Under the normal operating position of equipment, the power equipment external insulation can be in order to avoid clean non-maintaining.Save the human and material resources of a large amount of cleaning external insulations; Coating surface has hydrophobicity, thereby has prevented that effectively cement and chemical industry filth at its surface scale, can be widely used in various natural, industrial environments; Excellent insulation performance, mechanical performance are good, strong adhesion, anti-dust adhere to, corrosion-resistant, the life-span long, anti-corona, ageing-resistant, and has good anti-shoe ice effect and good weather resisteant; Coating does not fire, and solidifying the after-combustion grade is the FV-0 level, non-poisonous substances.

The beneficial effects of the utility model are: water-proof stain-resistant type reactor of the present utility model, have protection against the tide, waterproof, antifouling, characteristics such as electric insulating quality is good, and prolong the useful life of reactor.Strong, the anti-marquis of PRTV antifouling flush paint layer hydrophobicity and migration of hydrophobicity, high-low temperature resistant can be at-50 ℃--and 180 ℃ of temperature are medium-term and long-term to keep premium properties such as gentle elasticity, good, the nontoxic non-corrosiveness of adhesive force, storage period length, easy construction, integrated cost is low.
