Abstract

The invention relates to the field of cable accessories, and specifically relates to an isolating insulation piece for a hexagonal insulating guide rod. The isolating insulation piece is provided witha tubular body made of an elastic insulating material, wherein the tubular body is internally provided with a hexagonal inner hole matched with the rod body of the hexagonal insulating guide rod in shape, the outer wall of the tubular body is provided with at least seven insulating umbrella skirts arranged side by side, the skirt edges of each insulating umbrella skirt at two sides are symmetrically inclined outwards, the inclination angle is 3-5 degrees, the internal part of the hexagonal inner hole of the tubular body is further tightly equipped with a detachable a support strip winding tube, and the radius of the support strip winding tube is not less than the side length of the cross section of the rod body of the hexagonal insulating guide rod. The sealing performance and the safetybetween the isolating insulation piece and the hexagonal insulating guide rod are greatly improved. Meanwhile, the isolating insulation piece is convenient and efficient to operate and improves the construction efficiency.

Description

technical field [0001] The invention relates to the field of cable accessories, in particular to an isolation insulating part for a hexagonal insulating guide rod. Background technique [0002] Due to the SF in the 10kV ring network cabinet 6 The three-phase space of the circuit breaker is small, limited by the internal space of the ring network cabinet, SF 6 The three-phase isolating switch of the circuit breaker is usually installed on the hexagonal insulating rod, while the SF 6 The main shaft connection sleeve accessories of the circuit breaker are installed outside the ring network cabinet to facilitate the operation of closing and opening. However, in the actual power distribution process, due to the relatively compact internal space of the ring main unit, the conductors of the three-phase isolating switch installed on the hexagonal insulating guide rod and the SF 6 The distance between the main shaft connection sleeve of the circuit breaker is relatively close, and...
