Special nut for preventing heating of outdoor 10kV pole-mounted circuit breaker pile head

The invention discloses a special anti-heating nut for a pile head of an outdoor 10kV pole-mounted circuit breaker, and belongs to the technical field of electrical mechanical equipment. The device comprises an insulator. A vertically upward copper screw rod is arranged on the insulator; a first copper nut and a second copper nut which can move are mounted on the copper screw rod; the lower side of the first copper nut is attached to the top end face of the insulator. A first cushion clamp and a second cushion clamp are fixedly installed on the opposite end faces of the first copper nut and the second copper nut respectively. A flow guide transition piece is further installed between the first cushion clamp and the second cushion clamp. The side part of the diversion transition sheet extends outwards, and the extending end is provided with a drainage connector lug; a positioning screw hole is further formed in the top of the second copper nut; a locking assembly is mounted at the positioning screw hole; the s
