Abstract

The invention discloses an online monitoring system for carrying capacity of a cable, belonging to the technical field of electrical equipment. The online monitoring system comprises an optical fiber grating temperature sensor, a load current collector and a micro processor, wherein the optical fiber grating temperature sensor is used for monitoring the ambient temperature of the outer skin of the cable and the cable in real time; the load current collector is used for monitoring the cable load current in real time; and the micro processor is used for receiving the temperature information monitored by the optical fiber grating temperature sensor, and the current magnitude information collected by the load current collector, and acquiring the carrying capacity of the cable by combining structure parameters and the arrangement state of the cable, wherein the load current collector is connected with the micro processor by a photoelectric converter; and the optical fiber grating temperature sensor is connected with the micro processor. The online monitoring system achieves real-time monitoring on the cable current, can acquire the current residual carrying capacity of the cable in real time, and can randomly expand according to the requirements, so that overload and light-load of the cable can be effectively avoided to improve the utilization efficiency of the cable and guarantee the stable operation of the circuit.

Description

Technical field [0001] The invention belongs to the technical field of power equipment, and particularly relates to an online monitoring system for the current carrying capacity of a cable. Background technique [0002] At present, with the rapid development of society, electric energy as a clean energy is playing an increasingly important role in human society. As one of the indispensable carriers in the process of electric current transmission, the performance and characteristics of cables determine the quality of power transmission. Every aspect of the power transmission safety performance; among the multiple performance indicators of the cable, the current carrying capacity of the cable, as an important parameter during the operation of the cable, has attracted increasing attention; [0003] Traditional methods for monitoring the current carrying capacity of cables include thermocouple method and infrared thermal imaging camera. These methods have certain defects and cannot mee...
