Abstract

The invention discloses a double-insulating layer electric wire provided with a spiral ring sliding sleeve for arc-extinguishing interception and capable of preventing fire. The double-insulating layer electric wire structurally comprises a double-layer insulating sleeve, an inner tube shell, a spiral ring sliding brush device, a sealing ring, a three-hole slot bundled tube, a wire core thin shelltube and a copper core wire rod. The double-layer insulating sleeve matches with the spiral ring sliding brush device, reverse hook spikes for protecting the copper core wire rod are rotated hierarchically, and the spikes are pressed for avoiding the phenomenon of extension deformation; and arc static electricity input into an inner circuit is also provided with the magnetic guided winding rotation arc extinguishing effect of a lining plate pulley frame, so that static electricity caused by reverse ion collision is avoided, a same-direction trajectory of the inner circuit is improved, the effect of spirally transmitting a current is achieved, a ratchet type motion trajectory of a ratchet ring groove and an outer ring soft brush needle is enhanced, structural relationships between the spikes at all angles and the outer surface of a copper core are differentially distributed around the center of a circle according to scale values, the prevention of inner and outer fire hidden dangers ofthe electric wire is guaranteed, and the sudden increase of electric arcs and electric sparks is effectively prevented.

Description

technical field [0001] The invention relates to an arc-extinguishing and current-cutting double-layer electric wire with a spiral ring sliding sleeve capable of preventing fire, which belongs to the field of electric cables. Background technique [0002] Double-layer insulated wires are circuit transport components used in high-voltage electricity and household distribution lines. High-voltage electricity is the impact force of circuit transmission, which requires double-layer rubber insulation to withstand high-altitude currents and air friction. The double-layer insulation effect of the electric wire is to avoid the potential safety hazard caused by people directly touching and repairing the electric wire, so that the relatively high-safety electric wire has a built-in structure. The shortcomings of the current technology to be optimized are: [0003] In the double-layer insulation wire, the phenomenon of external leakage is prevented, but the anti-hook tip on the outer su...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a double-layer insulation electric wire with a spiral ring sliding sleeve arc extinguishing and interception that can prevent fire, so as to solve the problem of external leakage in the double-layer insulation wire. , but the anti-hook tips on the outer surface of the inner battery core rod will cause the friction and deformation of the two thorn tips to short-circuit the electric spark. The cumbersome operation of truncating and lapping also makes the friction between the double-section cells and the internal circuit unstable, and the horizontal free electrons cause dissipation, causing excessive consumption of internal circuits and wasting power, causing early replacement of wires and cables, shortening service life and wasting material costs. , leading to the problem that the peripheral material of the wire is complete, but the internal heat of the inner core electric spark is particularly fragile
