Abstract

The invention relates to a softening device. The softening device comprises a heating mechanism and a supporting mechanism; the supporting mechanism is installed on a cable, the supporting mechanism is provided with a circulating air duct, and the circulating air duct is arranged in the circumferential direction of the cable; and heat generated by the heating mechanism can be transmitted to the circulating air duct, and a hot air flow exists in the circulating air duct. The softening device can form the circulating air duct arranged around the cable on the outer side of the cable, and the heatis transmitted to a cold air flow located in the circulating air duct through the heating mechanism, so that the cold air flow in the circulating air duct is converted into the hot air flow, and a protective layer is heated through flowing of the hot air flow in the circulating air duct. In the whole heating process, the cable does not need to be directly heated by the heating mechanism, so thatthe risk that the cable is burnt is reduced. Meanwhile, whole-process operation of an operator is not needed in the heating process, so that the risk of scalding the operator is reduced.

Description

technical field [0001] The invention relates to the technical field of electrical machinery, in particular to a softening device. Background technique [0002] Both high-voltage land cables and 110KV cables are coated with an anti-corrosion protective layer. Generally, the outer layer of the cable aluminum is coated with an asphalt layer for anti-corrosion, and the plastic sheath is coated. But when the cable is used as a cable accessory, the anti-corrosion protection layer on the outer layer of the cable needs to be removed. However, because the protective layer is thick and the cable is firmly bonded to the asphalt layer, the stripping operation will be more difficult. In traditional technology, gas guns are mostly used to heat the protective layer, so that the asphalt layer and plastic sheath are softened and then removed and cleaned. However, there is a relatively large operational risk in this method. In case of improper operation, it may cause the protective layer to...
