Abstract

The invention discloses a moistureprood processing method of an electric insulation board, which is characterized in that the electric insulation board is externally provided with a vinyl ester resin material coating which is prepared by vinyl ester resin and a curing agent, wherein the mass of the curing agent is 1.5-2% of the mass of the vinyl ester resin; and the electric insulation board also comprises a curing accelerator, and the mass of the curing accelerator is 0.2-1% of the mass of the vinyl ester resin. According to the invention, by utilizing the known anticorrosive material-vinyl ester resin, the moistureproof requirement of the electric insulation board used under high voltage can be met, the insulation strength of the epoxy resin board can be strengthened, the new use of the vinyl ester resin can be found and utilized, and the unexpected effect is achieved.

Description

technical field [0001] The invention relates to an electrical insulation board, in particular to a moisture-proof treatment method for the electrical insulation board. Background technique [0002] In the current high-voltage electrical equipment, the use of insulating boards is almost ubiquitous, and the use of epoxy resin boards is the most common. Its mechanical properties are superior to PVC boards, PE boards and bakelite boards. For example, the grounding box series products must be used in 110kV cable lines, because the grounding box series products are used for the sheath of 110kV cables, and the required voltage level reaches DC 20kV / min, and these products are usually installed in cable trenches. Moisture will inevitably be encountered during use, and any insulating board material will have its own water absorption rate. If it encounters moisture, the insulation performance of the insulating board will be significantly reduced. If it continues to be used, it is lik...
