The electrical insulation plate is characterized in that a vinyl ester resin material coating is arranged outside the electrical insulation plate and on all the outer surface of the electrical insulation plate. By coating the vinyl ester resin material coating on the electrical insulation plate, the moisture-proof treatment requirements of the electrical insulation plate used under high voltage can be met, the insulation strength is enhanced, and unexpected effect can be achieved.
Description
Technical field
The utility model relates to a kind of electric insulation plate, particularly a kind of electric insulation plate that strengthens the damp proof insulation performance.
Background technology
In present high voltage electric apparatus, the use of insulation board is almost ubiquitous, and the use of epoxy resin board is the most common, and reason is that epoxy resin board adopts epoxy resin and glass wool cloth is high and is pressed into, good insulation preformance, and its mechanical performance is better than PVC plate, PE plate and bakelite plate.as necessary matching used grounding box series of products in the 110kV cable line, because the grounding box series of products are used for the sheath of 110kV cable, the electric pressure that requires reaches direct current 20kV/min, and these products all are mounted in cable trough usually, inevitably can run into moisture in routine use, and any insulation board material all can existence itself water absorption rate, if run into moisture, the insulation property of insulation board will obviously descend, if continuing to use probably to make electric equipment break down, affect the normal operation of cable line, so being necessary use carries out protection against the tide and processes, make not affected by moisture of high voltage electric equipment, can continue normal operation.
In prior art, the protection against the tide of low-voltage (being 400V and following) electric insulation plate is processed very common, and moistureproof treatment process is also very ripe.But in higher voltage, namely reach 10kV in insulating requirements, 20kV even, so present moistureproof treatment process is with inapplicable: existing moistureproof treatment process can cause the sharply resistance of insulation board to descend under the impact of moisture, make leakage current increase under the voltage of direct current 10kV, finally cause high-pressure side to discharge over the ground, electric equipment will break down like this, affects the normal operation of circuit.That is to say, existing moistureproof process application can not satisfy at high pressure the instructions for use that takes into account in electric insulation plate humidity resistance and the dielectric strength of high pressure use simultaneously.
As everyone knows, vinyl ester resin is a kind of anti-corrosion material commonly used, and it has good mechanical performance and good chemical-resistance.But it is used for performance moistureproof and that take into account dielectric strength and is never put down in writing and utilized.
The utility model content
The purpose of this utility model is to provide a kind of electric insulation plate that strengthens the damp proof insulation performance, and this electric insulation plate moisture effect is good, has simultaneously good dielectric strength concurrently.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of electric insulation plate that strengthens the damp proof insulation performance is characterized in that, in the outer setting vinyl ester resin material coating of electric insulation plate.
Described vinyl ester resin material coating is arranged on whole outer surfaces of electric insulation plate.
Described vinyl ester resin material coating layer thickness L:0＜L≤0.5mm.
Above-mentioned vinyl ester resin material is made by vinyl ester resin and curing agent; Wherein, the quality of curing agent is 1.5% ~ 2% of vinyl ester resin quality.
It is one of following that described curing agent refers to: methyl ethyl ketone peroxide; Low content of hydrogen peroxide, the MEKP of high dimer content; Isopropyl benzene hydroperoxide; The dibenzoyl peroxide powder.
Described vinyl ester resin material also comprises curing accelerator, and the quality of curing accelerator is 0.2% ~ 1% of vinyl ester resin quality.
As preferably, described curing accelerator refers to cobalt accelerator.
As optimum embodiment, described curing agent refers to methyl ethyl ketone peroxide, and methyl ethyl ketone peroxide is that quality is 2% of vinyl ester resin quality; The quality of described cobalt accelerator is 0.5% of vinyl ester resin quality.
Described vinyl ester resin material coating is arranged on electric insulation plate by the mode of brushing.
Vinyl ester resin material in the utility model stirs all material at normal temperatures and makes.
Design principle of the present utility model is such: 1, vinyl ester resin is a kind of anti-corrosion material commonly used, and it has good mechanical performance and good chemical-resistance, is applied in numerous fields as corrosion-inhibiting coating.But the moisture barrier coatings of making electric insulation plate take it as main component is Records never also.The moisture barrier coatings of the electric insulation plate that it is made as main component makes electric insulation plate possess very strong dielectric strength, reached purpose less than effect, solved and perplexed the moistureproof problem that electric insulation plate uses at high pressure conditions always.2, the vinyl ester resin ratio of viscosities is larger, the structure of epoxy resin board of considering the electric equipment that high pressure conditions uses is changeable, if with the mode of soaking, be difficult to make vinyl ester resin to cover equably the surface of epoxy resin board, and vinyl ester resin has higher mechanical strength, if cover layer is blocked up, easily ftracture at product installation process floating coat, so select the mode of brushing, and guarantee that coating layer thickness is no more than 0.5mm, do not need to be heating and curing (after adding curing agent, normal temperature cure).
The utility model possesses following outstanding advantages and effect with respect to prior art:
The disclosed electric insulation plate of the utility model by utilizing known anti-corrosion material---vinyl ester resin, has not only satisfied the moistureproof processing requirements of the electric insulation plate of high voltage use, has also strengthened the dielectric strength of electric insulation plate.
