Transformer substation equipment online monitoring method and device

Abstract

The invention belongs to the technical field of transformer substation monitoring, and particularly relates to a transformer substation equipment online monitoring method and a transformer substationequipment online monitoring device. The transformer substation equipment online monitoring method comprises the steps of acquiring transformer substation equipment information collected by sensors arranged at different substation equipment by means of a vibration alarm; judging whether the transformer substation equipment information is normal or not according to pre-stored standard transformer substation equipment information by means of the vibration alarm; if the vibration alarm judges that the transformer substation equipment information is not normal, sending a vibration signal to an information processing platform; receiving the vibration signal by the information processing platform, and determining the fault of the transformer substation equipment according to the vibration signal.By the adoption of the scheme, the state of the transformer substation equipment can be monitored through various different sensors. As a result, various fault hidden dangers caused by the long-timeand high-load operation of the transformer substation equipment can be found in time. The safe and stable operation of the transformer substation equipment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of substation monitoring, in particular to a method and device for on-line monitoring of substation equipment. Background technique [0002] Substation equipment mainly includes transformers, switching equipment for opening and closing circuits, busbars for collecting current, transformers for measurement and control, instruments, relay protection devices, lightning protection devices, dispatching communication devices, etc. Some substations also have reactive power compensation equipment. The transformer is the main equipment of the substation, and the switchgear, including circuit breakers, disconnectors, load switches, high-voltage fuses, etc., are all equipment for disconnecting and closing circuits. [0003] At present, substation equipment only relies on remote signaling and telemetry to judge the operating status of substation equipment. If such hidden faults occur, if they cannot be discovered in t...
