There is also a greater risk of associated devices within the heat radiation range and within the electrical radiation range when the abnormal device temperature exceeds a threshold. And the risk of the associated equipment meeting the heat radiation range and the electric radiation relation is higher, and the risk level of the associated equipment can be quickly determined by operation and maintenance personnel through carrying out risk display of different levels on the associated equipment with different risks so as to formulate a differential coping strategy.

Wherein, the step 4 further comprises:
step 4.1: when the operation state of the secondary equipment is abnormal, an operation and maintenance person controls the virtual isolating switch in the digital twin model of the transformer substation to enable the corresponding entity isolating switch to be opened, so that the secondary equipment and the corresponding primary equipment are subjected to signal isolation, and misoperation is prevented.
Step 4.2: and after the fault of the secondary equipment is relieved, the virtual isolating switch is automatically closed according to a fault relieving signal, so that the physical isolating switch is closed, and the secondary equipment is isolated from the corresponding primary equipment relieving signal.
The secondary equipment is equipment for measuring, monitoring, controlling and protecting the operation conditions of the primary equipment and the system, so that when the secondary equipment fails, the measurement data of the primary equipment can be inaccurate or the primary equipment is erroneously controlled, and therefore, signal isolation is carried out through the isolating switch, and the system is automatically recovered after the failure is relieved.
Compared with the prior art, the invention provides the operation and maintenance health analysis method and system for the transformer substation based on digital twinning, which are used for constructing the digital twinning transformer substation which is completely the same as the entity transformer substation in a digital space, realizing virtual-real interaction and iterative symbiosis, thereby realizing the whole domain perception, the accurate judgment of faults, the accurate and clear positioning, early warning and time effectiveness of the transformer substation equipment, ensuring the safe and reliable operation of the transformer substation and reducing the operation and maintenance cost. By constructing a relation map for each virtual device in the model, when the fault diagnosis is carried out on the device, the potentially-risky device associated with the current device can be obtained through the relation map, and corresponding prompt is carried out through the digital twin model. The primary equipment and the secondary equipment acquire associated equipment according to different relation mappings, so that different security levels and functional characteristics of the primary equipment and the secondary equipment are met. By displaying the risks of different levels on the associated equipment with different risks, the operation and maintenance personnel can be helped to quickly determine the risk level of the associated equipment so as to formulate a differential coping strategy.
