Cable on-line detection equipment

Abstract

The invention discloses cable on-line detection equipment which comprises a supporting frame, an upper supporting plate and a lower supporting plate are arranged on the supporting frame, a sliding rail is arranged between the upper supporting plate and the lower supporting plate, two sliding blocks are symmetrically arranged in the sliding rail, and an upper outer ring and a lower outer ring are arranged on the two sliding blocks respectively. The upper outer ring and the lower outer ring are respectively provided with a bearing seat, a bearing is installed in each bearing seat, a rotating ring body is fixedly arranged on an inner ring of each bearing, an annular groove is formed in each rotating ring body, a rotary ring body is rotationally arranged in each annular groove, a driving mechanism for driving the corresponding rotary ring body to rotate is arranged on each rotating ring body, and a plurality of sliding mechanisms are uniformly distributed on the surface of each rotary ringbody around the circle center of the rotary ring body. According to the invention, a cable can be automatically rotated and reset before testing, it is ensured that the cable is detected in a normalstate, and the detection precision is ensured.

Description

technical field [0001] The invention relates to cable detection equipment, in particular to online cable detection equipment. Background technique [0002] The power cable is used to transmit and distribute large-scale electric energy in the main line of the power system, and the control cable directly transmits the electric energy from the power distribution point of the power system to the power connection line of various electrical equipment and appliances. Its main feature is to extrude (wind) the insulation layer outside the conductor, twist several cores (corresponding to the phase wire, neutral wire and ground wire of the power system), and then add a sheath layer, such as plastic or rubber sheathed wire and cable. Main technology has drawing, stranded, insulation extruded (wrapped), stranding, armouring, sheath to extrude etc., and the different operation combinations of various products have certain difference. According to the voltage level, power cables are divid...

Problems solved by technology

However, the existing tension detection devices all use clamp-shaped clamps to clamp the cable. This method is insufficient for clamping tension testing. Because the cable body will be twisted and twisted, when it is sent out at the hoist due to Testing without automatic loosening, the detection of twisted cables will easily cause errors, which affects the accuracy of cable tension detection data
