Description

technical field

[0001] The invention relates to the technical field of light-curing materials, in particular to an acrylate monomer and a preparation method thereof, an acrylate monomer repair material and an application thereof. Background technique

[0002] Dry-type air-core shunt reactors have the advantages of small maintenance, low cost, and easy installation. They are widely used in power systems. As important reactive power compensation equipment in substations, dry-type air-core shunt reactors are mainly used to provide inductive reactance power consumption. The excess capacitive reactive power of the system is used to maintain the voltage level of the power system, and its safe operation is directly related to the power quality and the safety of the power grid. Dry-type air-core shunt reactors are mostly made of glass fibers impregnated with epoxy resin to encapsulate and insulate the coil, and then cured at high temperature to complete. Since dry-type air-core shun...
