Abstract

The invention relates to a softening device. The softening device includes: a heating mechanism; a supporting mechanism, the supporting mechanism is installed on the cable, the supporting mechanism has a circulating air duct, and the circulating air duct is arranged along the circumference of the cable; the heat generated by the heating mechanism can be transferred to the circulating air duct, and the circulating air duct has Thermals. The softening device can form a circulating air duct around the cable on the outside of the cable, and transfer heat to the cold air flow in the circulating air duct through the heating mechanism, so that the cold air flow in the circulating air duct can be converted into a hot air flow, which is circulated by the hot air flow Flow heating protection layer in the air duct. During the whole heating process, there is no need for a heating mechanism to directly heat the cable, thereby reducing the risk of the cable being burned. At the same time, the operator does not need to operate the whole process during the heating process, thereby reducing the risk of scalding the operator.

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...
