Description

Power equipment surface crack detection device

Technical Field

The utility model relates to a detect technical field, specifically be a power equipment surface crack detection device.

Background

The cable wire is used as a power and signal transmission medium and is widely applied in life. The cable outer sheath is positioned on the outermost layer of the cable and mainly adopts two materials of polyvinyl chloride (PVC) or Polyethylene (PE). It has the main functions as follows: protection and insulation; the cable is prevented from being corroded in the laying environment with moisture and corrosive substances. For cables with metal sheaths, the outer sheath on the outermost layer of the cable is designed to protect the metal sheath (e.g. a corrugated aluminum sheath) from corrosion by the substances surrounding the cable; for cables without metal sheaths, the outer sheaths directly play a role in protecting and sealing the main insulation, and the electromagnetic induction of conductor current is prevented from being generated in the high-voltage transmission process. In order to avoid induced voltage from forming a circulating current on the metal sheath and reduce the current-carrying capacity of the cable, the outer sheath of the cable must have good insulating performance so as to insulate the metal sheath from the ground. The outer sheath of the cable is damaged, and if the outer sheath is damaged, the circulation current of the metal sheath of the cable is increased, so that the transmission capacity of a cable line is reduced; and the metal sheath of the cable is corroded, so that the main insulation of the cable is endangered until the insulation is broken down, and accidents happen.

The crack detection of the existing cable wire is carried out by sleeving the cable wire with a crack detection sleeve, then the cable wire is driven by a driving device to advance, the crack detection is carried out by a sensor, the light is turned on and the advance is stopped when the crack detection sleeve is detected, the detection device of the cable of the Chinese patent publication No. CN204758572U is a detection mode, but the crack detection sleeve needs to be sleeved in from the cable head when the sleeve is sleeved on the cable, the end heads of the common cable wires are provided with connectors which are larger than the diameter of the cable wire, the sleeving is inconvenient, the crack detection cannot be carried out at any position, and the crack detection is stopped when the crack detection sleeve is detected, so that. Therefore, the device for detecting the surface cracks of the electrical equipment is provided.
