[0002] Switchgear is a kind of electrical equipment, which mainly plays the role of power generation, transmission, distribution and power conversion in the power system. There are various main control lines and sub-control lines inside, and the structure is complex;
[0003] Most of the traditional switchgear diagnosis methods are based on the failure evaluation model proposed by the failure probability and failure consequences. However, in the actual use process, only the detection and diagnosis of failure probability and failure consequences cannot fully reflect the health status of the switchgear operation, for example: The actual number of operating equipment in the switchgear, the factors affecting the operation of the equipment, and the proportion of the impact of each equipment in the overall operation are all part of the health index of the switchgear; this makes the status evaluation of the switchgear deviate greatly

Embodiment Construction
[0053] Hereinafter, the technical solutions of the present invention will be described in detail through specific embodiments.
[0054] like figure 1 As shown, the present invention proposes a method for evaluating the state of health of a switchgear. The switchgear includes various devices or circuits, and the evaluation method includes the following steps S1 to S6:
[0055] S1: Establish a health risk assessment model for switchgear operation, and perform detection and configuration on the health risk assessment model;
[0056] Use the existing health risk assessment model, and perform detection configuration processing on the health risk assessment model. The detection configuration includes parameters such as equipment rated power, operating temperature, and load topology correlation. The specific detection configuration can be set according to specific conditions, and then The operating health level of the specific switchgear can be obtained.
[0057] S2: According to t...

The invention discloses a switch cabinet health state evaluation method and system. The method comprises the following steps of establishing a health risk assessment model of operation of a switch cabinet; detecting m influence factors of each device or circuit in the switch cabinet, and obtaining m influence factor detection data; comparing the m influence factor detection data with an influencefactor predetermination threshold ni to obtain a health state value wi of each device or circuit; calculating and acquiring a health degree value hj of each device or circuit according to the influence factor predetermination threshold ni and the health state value wi; through the health degree value hj, calculating and acquiring an operation health degree value H of an overall switch cabinet; obtaining an operation health level of the switch cabinet through comparing the operation health degree value H of the overall switch cabinet with a predetermined health degree threshold in the health risk assessment model; and according to the health risk assessment model, accurately evaluating an operation health state of each device or circuit in the switch cabinet.
