Description

Technical Field

[0001] The present invention relates to the technical field of transformer substations, and in particular to a transformer substation internal fault inspection device and an implementation method thereof. Background Art

[0002] Substation is a place where voltage is changed. Electric energy generated by power plants is transmitted to distant places through substations. The voltage must be increased and converted into high voltage electricity. When it reaches the vicinity of users, the voltage must be lowered as needed. This work of raising and lowering voltage is completed by substations. The main equipment of substations is switches and transformers. According to the size, small ones are called substations. Substations are larger than substations. Substations generally refer to step-down substations with voltage levels below 110kV; substations include "step-up and step-down" substations of various voltage levels. Substations need to be monitored in real time, and if a fault occurs, it needs to be handled immediately.

[0003] Patent number CN201510357560.7 is a method for online fault analysis of substation network, including two parts: module setting and implementation process. The module is provided with four modules, which are connected in sequence as: fault message acquisition module, fault message parsing module, analysis and diagnosis module and result display module; the implementation process is to parse and analyze the message information online, in real time or in the substation, and finally determine whether there is a fault in the substation network system, and inform the operator of the result. The invention can automatically and quickly find out the cause of the substation network fault, make up for the defect of the existing technology that manual troubleshooting is required, shorten the time for determining network faults, and improve the efficiency of substation network fault handling. However, the existing substation faults are all detected by line faults through the network where the substation is located, resulting in the inability to collect images of components inside the substation in real time. Fault information of external force destruction and line burnout cannot be collected. If an image collector is installed inside the substation, its wireless transmission will interfere with the normal operation of the substation. Summary of the invention
