Cooling and waste heat utilization system for reactive power compensation device of booster station and use method of cooling and waste heat utilization system

The invention discloses a cooling and waste heat utilization system for a reactive power compensation device of a booster station and a use method. The cooling and waste heat utilization system comprises an SVG power cabinet and a cooling assembly. The waste heat recovery system is communicated with the SVG power cabinet and the cooling assembly through a refrigerant water pipeline; the absorption refrigerating unit comprises a generator, a condenser, an evaporator and an absorber, the generator and the condenser are communicated with each other, the evaporator and the absorber are communicated with each other, lithium bromide-water solution working medium pairs are arranged in the generator, the first condenser, the first evaporator and the absorber, and a solution heat exchanger is arranged between the generator and the absorber. A working medium circulating pipeline is arranged among the solution heat exchanger, the generator and the absorber; the waste heat recovery system is inserted into the generator;
