Optionally, when diameter measurement is needed, an opening control instruction is sent to the first wire and cable diameter detection assembly and the second wire and cable diameter detection assembly, so that the control device in the first wire and cable diameter detection assembly and the second wire and cable diameter detection assembly can control the telescopic device to perform telescopic motion, when the telescopic device reaches the motion top end, the telescopic device stays for a preset time, so that the control device can obtain the motion distance of the measuring scale, the diameter of the wire and cable is obtained, and the diameter is sent to the control assembly. And after the preset time is up, the control equipment controls the telescopic equipment to lift. When diameter detection is not required, a closing control command is sent to the first wire and cable diameter detection assembly and the second wire and cable diameter detection assembly. The moving top end is the position where the second bearing cannot move downwards continuously due to the existence of the internal wire and cable, and the preset stopping time is used for obtaining the more accurate diameter of the wire and cable after the measuring scale is stabilized.
The predetermined diameter range may be a range of two diameters, for example, a typical diameter plus or minus 1mm is a standard diameter range, for example [0.9, 1.1], in centimeters. It should be noted that, when the preset diameter range corresponding to the first diameter is [0.9, 1.1], the corresponding plastic-coated thickness, for example [1.0, 1.2], needs to be added to the preset diameter range corresponding to the second diameter.
The quality detection method of the electric wire and the electric cable further comprises the following steps:
when the first resistor clamping clamp and the second resistor clamping clamp respectively clamp the two ends of the wire and the cable, receiving a first resistor sent by a resistor tester;
and when the first diameter and the second diameter both accord with the preset diameter range and the first resistance accords with the preset resistance range, determining that the quality of the electric wire is qualified.
When the first resistor clamping clamp and the second resistor clamping clamp respectively clamp two ends of a wire and a cable, the air heater or the refrigerator is started, and the temperature of the sealed space in the insulating box is stable, the second resistor sent by the resistor tester is received;
and when the first diameter and the second diameter both accord with a preset diameter range, and the first resistor accords with a preset resistance range, and the second resistor accords with a preset high-temperature resistance range or a preset low-temperature resistance range, determining that the quality of the wire and the cable is qualified.
It should be noted that, when the air heater is used to heat the air in the insulating box, when the air is heated to the preset temperature, the preset time is delayed, so that the air in the insulating box is stabilized to the preset temperature, and the temperature of all the wires and cables is uniform. The preset time is not limited in this embodiment, and may be specifically set according to the weight of the electric wire and the cable.
According to the quality detection method of the electric wire and the electric cable, the quality of the electric wire and the electric cable is determined to be qualified when the diameter before plastic coating, the diameter after plastic coating, the normal temperature resistance and the high temperature or low temperature resistance of the electric wire and the electric cable are detected respectively and meet preset conditions, and the quality of the electric wire and the electric cable is determined to be unqualified when any one of the detection of the diameter before plastic coating, the diameter after plastic coating, the normal temperature resistance and the high temperature or low temperature resistance does not meet the preset conditions, so that comprehensive quality detection can be carried out on the electric wire and the electric cable, and the detection result is accurate.
