Optical fiber composite high-voltage power cable

Abstract

The invention belongs to the technical field of cables, and particularly relates to an optical fiber composite high-voltage power cable, which comprises a composite cable and a bracket, and is characterized in that the bracket is used for fastening the composite cable; an air cylinder is fixedly installed on the side wall of the support. Two air outlet pipes are fixedly mounted on the side wall of the air cylinder, electromagnetic valves are fixedly mounted in the air outlet pipes, and after the electromagnetic valves in the air outlet pipes away from the push plate are switched on, the electromagnetic valves in the air outlet pipes close to the push plate are switched off; the air outlet pipe is externally connected with a whistle; after the composite cable is broken, the corresponding cable is shrunk, so that the push plate in the air cylinder with a large amount of air moves upwards under the action of the pushing force of the air, the push plate crosses the air outlet pipe, the air in the air cylinder enters the siren externally connected with the air outlet pipe through the air outlet pipe, and a warning sound effect is generated; and the effect of automatically prompting the maintenance personnel of the fracture position point after the optical fiber is fractured due to the stress influence is achieved.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to an optical fiber composite high-voltage power cable. Background technique [0002] The cable is usually a type of rope cable twisted by several or several groups of wires. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering. Composite cables refer to the twisting of optical fibers and wires, capable of carrying both optical and electrical signals. [0003] For example, a Chinese patent with application number CN201811410028.7 discloses a composite cable, which relates to the field of cables, including a cable core, an elastic layer is wrapped on the cable core, an optical fiber is spirally wound around the elastic layer, and an optical fiber is sleeved on the elastic layer. There is an elastic sleeve, an insulating layer is wrapped around the elastic sleeve, and a plurality of ...

Problems solved by technology

[0004] However, when users use composite cables to connect networks and circuits, they are limited by the indoor layout and need to bend the composite cables. The bending resistance of optical fibers and wires in composite cables is different. Wires and optical fibers bend synchronously, and optical fibers tend to break when subjected to large bending stresses

Since it is difficult for the naked eye to capture the specific situation of the fiber break, when the fiber is broken, it is difficult for the maintenance personnel to judge the fault, and it is not convenient for the maintenance personnel to repair the fiber;
