Cable adapter for power engineering

Abstract

The invention relates to a cable adapter for power engineering and belongs to the field of cable mounting and fixing structures. The cable adapter is mounted on a utility pole and includes a fixing ring, wherein the fixing ring is provided with a cable fixing portion; a wire tightening device is arranged on the fixing ring and adjacent to the cable fixing portion; the wire tightening device is provided with a wire tightening box; the side wall of the wire tightening box is provided with a wire tightening rod hole; the wire tightening device is provided with a wire tightening rod passing through the wire tightening rod hole; the wire tightening rod is provided with a stopping bump at one end outside the wire tightening box; a wire tightening wheel is rotatably connected to one end of the wire tightening rod in the wire tightening box; the wire tightening rod between the wire tightening wheel and the wire tightening rod hole is sleeved with a wire tightening spring; a fixing wheel is arranged on the bottom of the wire tightening box near the cable fixing portion; a wire tightening shaft is arranged on one end of the wire tightening rod in the wire tightening box; and the wire tightening wheel is mounted on the wire tightening shaft. The wire tightening device is arranged on the fixing ring keeps the cable in a moderately tight state in winter or summer.

Description

technical field [0001] The invention relates to the field of cable installation and fixing structures, in particular to a cable adapter for electric power engineering. Background technique [0002] With the rapid development of our country's economy, one after another electric towers stand in the mountains in the west, which also promotes the upgrading of electrical engineering equipment. [0003] Although the currently used cable adapters for power engineering can fix the cables, due to the uncertainty and complexity of the outdoor working environment, the cable adapters will loose the fixed structure and require maintenance by the staff. It is difficult to disassemble and assemble the connector as a whole on the utility pole, which reduces the maintenance efficiency of the staff. Now there is a need for a cable adapter with stable connection and easy disassembly and maintenance. [0004] In view of the above problems, the Chinese patent with the announcement number "C" N2...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned solution solves the problem that the existing cable adapters are integrally sleeved on the distribution brackets, which is difficult to disassemble and assemble conveniently, and reduces the maintenance efficiency of the staff. According to the principle of expansion and contraction, the cables will be very tight due to the low temperature in winter when the cables are lapped, and the cables will become longer and cause excessive sag when the temperature rises in summer. Line accident, arc sag is too large Even if there is no contact mixed line, arc discharge is prone to occur
