The invention provides fully-insulated and fully-sealed handcart type high-voltage isolating switch equipment, and belongs to the technical field of electrical equipment. The fully-insulated and fully-sealed handcart type high-voltage isolating switch equipment comprises a cabinet body frame, a solid-sealed polar column type isolation handcart switch, a three-phase integrated current transformer,a fully-sealed lightning arrester, an incoming cable terminal and a branch bus expansion cable terminal. The cabinet body frame comprises a secondary bus chamber, an instrument chamber, an isolation switch chamber, a bus chamber and a reserved compartment. According to the invention, the problems of serious dust pollution, easy condensation and the like due to the fact that the insulation capability is reduced are solved. Meanwhile, the problem that existing solid insulation switch cabinets, gas insulation switch cabinets, incoming switch cabinets or bus connection switch cabinets are weak incurrent carrying capacity can also be solved. Te equipment realizes the ideal unity of full insulation, full sealing, dust prevention, condensation prevention, strong current carrying capacity, handcart type high-voltage isolating switch, convenient operation, less operation and maintenance, or free operation and maintenance.
