Embodiment 1

[0017] Such as figure 1 As shown, a degassing device for a medium and high voltage cable cross-linking production line includes a degassing pipeline 1 and a cold air pipeline 2, the degassing pipeline 1 is a sealed pipeline, and the degassing pipeline 1 is provided with a heating device and an exhaust system, The cold air duct 2 is provided with a cooling fan, and the cable 3 passes through the degassing duct 1 and the cold air duct 2 in sequence during the production process.

[0018] Under the action of the traction device, the cable 3 passes through the degassing duct 1 and passes out from the cold air duct 2; the heating device heats the degassing duct 1 and the degassing duct 1 The temperature in the gas pipeline 1 is maintained at 60-70°C, and the exhaust system extracts the by-products precipitated from the cable 3 out of the degassing pipeline 1 to avoid the by-products precipitated from the cable 3 in the degassing pipeline 1 internal accumulation, resulting in safet...

Embodiment 2

[0025] The difference between this embodiment and Embodiment 1 is that the heating device is different, and the heating device includes a controller, a temperature sensor arranged in the degassing pipeline, and electric heating wires evenly distributed on the inner wall of the degassing pipeline, The controller controls and connects the heating wire according to the temperature value collected by the temperature sensor.

Abstract

The invention provides a degassing device for a middle-high-voltage cable crosslinking production line. The degassing device comprises a degassing pipeline and a cold air pipeline, wherein the degassing pipeline is a sealed pipeline, a heating device and a ventilation system are arranged on the degassing pipeline, a cold air fan is arranged in the cold air pipeline, and cables sequentially penetrate through the degassing pipeline and the cold air pipeline during production. The degassing device for middle-high-voltage cable crosslinking production line has the advantages of being scientific in design, strong in practicability, high in production efficiency, low in production cost, and reliable in production quality.

Description

technical field [0001] The invention relates to a degassing device, in particular to a degassing device for a medium and high voltage cable cross-linking production line. Background technique [0002] At present, the equipment for producing medium and high voltage power cables in China generally adopts catenary cross-linking production line, which includes extrusion, cross-linking, cooling system, traction, take-up and discharge device and control system. For cables with higher voltage levels, when peroxide insulation is used, the by-products produced during the cross-linking reaction will affect the quality of the cable, so the cross-linked by-products, that is, degassing, should be removed before the insulating core is shielded. At present, the most widely used degassing method is natural degassing, that is, under natural conditions, let the cross-linked by-products be eliminated by themselves, and it takes 2 to 4 days, and with the increase of the cable voltage level, the...
