Multifunctional solid-sealed polar pole

The invention relates to a multifunctional solid-sealed polar pole, which comprises a polar pole shell; a double-chamber arc extinguishing chamber which is provided with an upper isolation chamber anda lower arc extinguishing chamber, wherein the upper isolation moving contact and the static contact structure form an isolation fracture in the upper isolation chamber, the lower arc extinguishing moving contact and the static contact structure form an arc extinguishing fracture in the lower arc extinguishing chamber, and the design opening distance of the isolation fracture is larger than thatof the arc extinguishing fracture; the arc extinguishing insulation pull rod controls the arc extinguishing fracture to open and close; the isolation insulation pull rod controls opening and closing of the isolation fracture; the arc extinguishing insulation pull rod and the isolation insulation pull rod extend in parallel, the arc extinguishing insulation pull rod is located below the double-chamber arc extinguishing cham
