This invention discloses a modular, replaceable JP cabinet capacitor compensation switching integrated unit, comprising a cabinet interior including wiring terminals, two parallel vertical brackets, a first fixing bracket, a second fixing bracket, an air switch, a switching composite switch, a power capacitor, and a cooling fan. This invention pre-assembles the air switch and switching composite switch onto a single integrated mounting plate, achieving modular pre-assembly of the integrated unit.
