Description

Cable conductor and return line fixer Technical Field The utility model relates to a cable and return line fixer, and belongs to the technical field of cable and return line installation. Background When the single-point direct grounded single-core cable line is in power frequency short circuit, firstly, according to the requirement of whether the sheath induction voltage is met or not by taking the ground as a loop, if the power frequency induction voltage generated by the cable metal sheath exceeds the power frequency withstand voltage of the cable sheath insulation withstand strength or the sheath voltage limiter when the system is in short circuit, or when the electric interference strength of the adjacent weak current line needs to be restrained, a return line with lower impedance needs to be laid in parallel along the cable line, and the return line is generally provided with an insulating layer. The impedance of the return line and the grounding resistances at the two ends should achieve the aim of inhibiting the power frequency induction overvoltage of the cable metal sheath, and the section of the return line should meet the thermal steady-state requirement under the action of the maximum transient current. The arrangement of the return lines should minimize losses on the return lines during normal operation of the cable. When any terminal of the cable line is in a power plant or a transformer substation, the return line is communicated with a grounding grid with the electric, source and neutral wires grounded. When the single-loop cables are arranged in a straight shape (horizontal or vertical), the return lines are arranged according to three-seven openings, and the positions of the return lines are equidistantly changed for 1 time. However, in the engineering, the cable and the return line are usually installed in a fixed manner, and the distance between the return line and the cable is often not effectively ensured due to the differences of the laying environment and the construction technology, so that a certain safety risk exists. Disclosure of utility model Based on the above, the utility model provides a cable and return wire fixer, so as to overcome the defects in the prior art. The technical scheme of the utility model is that the cable and return line fixer comprises: the hoop unit comprises a first hoop and a second hoop which are arranged in parallel; The adjusting unit comprises an arc-shaped seat, a sliding block and a sliding rod, wherein the arc-shaped seat is arranged on the periphery of the first hoop, a sliding groove is formed in the arc-shaped seat along the periphery of the arc-shaped seat, the sliding block is slidably installed in the sliding groove, the sliding rod is arranged on the radial direction of the sliding groove, one end of the sliding rod is connected with the sliding block, and the other end of the sliding rod is connected with the second hoop. In one example, the sliding rod comprises a threaded rod, a threaded sleeve, a first nut and a second nut, the threaded rod is connected with the sliding block, the threaded sleeve is sleeved on the threaded rod, the outer end of the threaded sleeve is connected with the second hoop, the first nut is sleeved between the threaded sleeve and the sliding block, and the second nut is sleeved outside the threaded sleeve. In one example, the sliding groove is a convex groove or a dovetail groove. In one example, the first anchor ear comprises two first half anchor ears and a first fastener for closing and connecting the two first half anchor ears, and the arc-shaped base is arranged on the outer side of the circumference of the first half anchor ears. In one example, the second anchor ear comprises two second half anchor ears and a second fastener for closing and connecting the two second half anchor ears, and the end part of the sliding rod is connected with the middle part of the outer side of one second half anchor ear. The cable and the return line are fixed, and meanwhile, the position and distance adjustment limitation of the cable and the return line can be realized, so that the mounting efficiency is improved, and the safety distance of the cable and the return line can be ensured.
