Abstract

The invention relates to the field of monitoring in new energy power generation, and particularly discloses a buried cable temperature wireless monitoring system, which comprises a plurality of cable temperature monitoring devices, a power management module, a Lora communication module, a low-power-consumption processor module, a storage module, a clock module, an analog-to-digital conversion module, a signal processing module and a cable temperature data management platform. Herein, whether the temperature of the cable is normal or not can be judged according to the temperatures measured by the two temperature sensors, and when it is monitored that the cable is abnormal, the cable temperature data management platform can send out an alarm signal, so that the temperature of which monitoring point of the cable is abnormal can be quickly positioned, and the cable can be timely checked on site and quickly repaired.

Description

technical field [0001] The invention relates to a monitoring system in new energy power generation, in particular to a cable temperature monitoring system. Background technique [0002] In new energy wind farms, the voltage level from the fan to the box transformer is generally 690V, and a 1KV transmission cable is used; the voltage level from the box transformer to the step-up station is generally 35KV, and a 35KV transmission cable is used; The grid-connected voltage output by the compressor station is generally 110KV or 220KV, and the overhead cables of 110KV or 220KV are used to connect to the entire power transmission grid. [0003] In the new energy power generation on land, the 1KV power transmission cables from the fan to the box transformer and most of the 35KV power transmission cables from the box transformer to the step-up station are generally buried directly in the ground. The interference of the electronic switch itself makes the power generated by it contain...
