Description

Technical Field

[0001] The present invention relates to the field of power transmission equipment management, and in particular to a power transmission cable safety monitoring system. Background Art

[0002] The backup protection of transmission cables mainly includes distance protection, zero sequence protection, direction protection, etc. Voltage protection and current protection are generally not used alone because they cannot meet the reliability and selectivity requirements. Generally, the two are used together. And all kinds of protection are equipped with automatic reclosing devices. And the protection is divided into phase-to-phase and single-phase. If it is a double-circuit line, the direction needs to be considered.

[0003] When setting, attention should be paid to the coordination between various protections. The capacitance, mutual inductance, and branch lines of the transmission cables should also be considered. The branch transformer, system operation mode, grounding mode, reclosing mode, etc. Another important point is that for transmission cables of 220KV and above systems, due to the high voltage level, the fault is mainly a single-phase grounding fault, and sometimes the fault current may be less than the load current. And it is greatly affected by various line parameters. When configuring protection, it is especially important to fully consider the influence of various situations and parameters.

[0004] For example, CN118898810A discloses a method, device, electronic device and storage medium for identifying hidden dangers of external damage to power transmission cables, the method comprising: obtaining a monitoring image for monitoring construction machinery and power transmission cables, the monitoring image comprising a first image area where the construction machinery is located and a second image area where the power transmission cables are located; if the first image area and the second image area are at the same relative depth in the monitoring image, then calculating the actual distance between the construction machinery and the power transmission cables according to the first image area and the second image area; the relative depth represents the front-to-back relationship between the construction machinery in the first image area and the power transmission cables in the second image area in the monitoring image; if the actual distance is less than a preset threshold, then determining that the power transmission cables have hidden dangers of external damage. This technology can improve the accuracy of identifying hidden dangers of external damage to power transmission cables and accurately warn of hidden dangers of external damage to power transmission cables.
