Embodiment Construction

[0015] In order to better understand the technical solution of the present invention, the following will be described in detail through specific examples:

[0016] A method for laying a temperature-measuring optical cable of the present invention specifically includes the following steps:

[0017] Step 1. Connect the optical cable from the side of the monitoring host in the substation, and lay it along the far end of the cable to be temperature monitored.

[0018] Step 2, extend the optical cable close to the surface of the cable, and relay laying for a connection section every 100 meters in the forward direction of the optical cable.

[0019] Step 3, the optical cable is laid on the side of the cable, and the optical cable is fixed on the surface of the cable with nylon cable ties or fixing fixtures at intervals of 1-2 meters. If the cable is placed in a zigzag shape, use a fixing fixture to tightly fix the optical cable on the surface of the cable to be tested; if the cable...

Abstract

The invention discloses a temperature measurement optical cable laying method. The method comprises the following steps: 1, laying an optical cable from the side of a monitoring host in a transformersubstation to a far-end; 2, enabling the optical cable to extend by clinging to the surface of the cable, and performing relay laying by taking every 100m as a connecting section in the advancing direction of the optical cable; 3, arranging the optical cable on the surface of the cable by adopting a nylon binding tape or a clamp; and 4, setting a section of optical cable allowance every 500m, setting a section of optical cable allowance every time the laying environment of the temperature measurement optical cable changes, setting a section of optical cable allowance every time the temperaturemeasurement optical cable jumps from one section of electric cable to another section of electric cable, and setting a section of optical cable allowance at the tail section of the optical cable. According to the invention, reliable laying of attached optical cables of cables can be realized.

Description

technical field [0001] The invention relates to a method for laying a temperature-measuring optical cable used in the field of electric power engineering. Background technique [0002] With the increase of power load density, the load of power cables continues to rise. Superconducting cables have become a solution to ensure high-load and long-term power supply due to their super-carrying capacity. The first kilometer-level superconducting cable has been built in China, and the construction application and operation and maintenance management technology of superconducting cables are becoming increasingly mature. Due to the high cost of superconducting cables, the operation and maintenance work has many particularities compared with ordinary power facilities. The all-round and full-time online monitoring technology for cable operating status, operating environment, and external breakage risk has become an important support for the safe and stable operation of superconducting...
