The invention discloses a high-voltage explosion-proof power distribution cabinet for electrical equipment. The high-voltage explosion-proof power distribution cabinet comprises a power distribution cabinet body. Bottom legs are arranged at the lower end of the power distribution cabinet body. The power distribution cabinet body is manufactured through three layers of materials, a structural steel layer is arranged on the outermost layer, an anti-flaming plate is arranged on the middle layer, and a high-strength explosion-proof plate is arranged on the innermost layer. The interior of the power distribution cabinet body is divided into five spaces which include a busbar chamber, an upper disconnecting switch cabinet, a functional chamber, a lower disconnecting switch chamber and a cable chamber from top to bottom through cross beams. According to the high-voltage explosion-proof power distribution cabinet for the electrical equipment, cables are managed in order, the service life is long, the power distribution cabinet body achieves anti-corrosion and explosion-proof functions, and the high-voltage explosion-proof power distribution cabinet is especially suitable for being applied to electric systems of petroleum and petrochemical and ore industries in severe environments.
