Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1 to Figure 2 As shown in , a device for controlling the bending radius of a cable consists of

[0024] A device for controlling the bending radius of a cable, comprising two range finders 1, one of which is used to transmit a distance measurement signal, and the other range finder is used to receive a distance measurement signal, and the two range finders are respectively set At both ends of the arc cable 2 to be tested. The rangefinder is provided with an elastic buckle 3, and the elastic buckle is provided with a notch 4 for snapping into the curved cable to be tested. The elastic buckle can be easily stuck on the cable to fix the position of the distance finder. The elastic buckle is arc-shaped, and the inner ring of the elastic buckle matches the outer ring of the cable. The elastic buckle surrounds the cable to facil...

Abstract

The invention relates to the field of electric power construction, in particular to a device used for controlling the bending radius of a cable and a use method thereof. The device includes two distance measurers, wherein one is used for emitting a distance measuring signal and the other is used for receiving the distance measuring signal, and the two distance measurers are arranged at the two ends of a to-be-measured arc cable respectively. When the straight-line distance, measured by the distance measurers, between the two ends of the to-be-measured arc cable is smaller than a threshold value, and an alarm sends alarm voice to warn that the optical cable needs reconstruction. The device can accurately control the cable bending radius to prevent the cable from over bending.

Description

technical field [0001] The invention relates to the field of electric power construction, in particular to a device for controlling the bending radius of a cable and an application method thereof. Background technique [0002] Cables often need to be bent during cable laying, especially in the process of working in cable wells. Some cables have too much margin and need to be coiled in the cable well; some cables need to pass through the hole in the side wall of the cable well to lead to the pole; location and so on; when it comes to these jobs, the need to bend cables is unavoidable. There are relevant national standards for the minimum bending radius of cables. The value of the minimum bending radius is directly related to the outer diameter of the cable. For example, the minimum bending radius of a multi-core XLPE cross-linked polyethylene insulated power cable is usually 15 times the outer diameter. Other cables The ratio between the minimum bending radius and the outer ...
