Problems solved by technology
[0017] It has been seen that both of these key aspects can lead to large imprecisions in the assessment activities
[0018] Furthermore, current situation-based assessment methods typically do not provide information about the accuracy of their assessment data and how to improve the accuracy of their assessment data

Embodiment Construction
[0031] The present invention relates to a method 1 for evaluating the health status of industrial equipment S.
[0032] In principle, the device S may be any industrial equipment or system of a group having a component or component that is mutually active.
[0033] Preferably, the device S is a low pressure, a medium voltage or a high pressure electrical device or system, such as low pressure, medium pressure or high pressure switching devices, switching devices, distribution networks, and the like.
[0034] Typically, the following theoretical assumptions are based on the method of the invention:
[0035] - Any industrial equipment may suffer from faults;
[0036] - One or more mutually exclusive "fault mode" together leads to the failure of the device;
[0037] - One or more mutually exclusive failure causes work together at the origin of each fault mode.
[0038] Within the framework of the present invention, the "fault mode" of the industrial equipment is defined as the determ...

A method (1) for assessing the health of industrial equipment (S) having one or more identified failure modes (F 1 ,...,Fn), each of the failure modes has one or more identified failure causes (FC D1 ,…,FC DK ) and / or one or more undetermined fault causes (FC U1 , FC UM ), characterized in that it comprises: - Obtaining (2) input data relevant to said device (D IN ); - for each failure mode identified for the device in question (F i ) calculation (3) failure mode evaluation data (R Fi 、RUL Fi 、A Fi 、RSK Fi 、POF Fi ), wherein the calculation of the failure mode evaluation data includes: - If the failure mode (F i ) with one or more identified fault causes (FC D1 ,…,FC DK ), then: - perform (31) the first calculation process (11) to determine for each fault cause (FC Dj ) to calculate the failure cause evaluation data (R FCj 、RUL FCj 、A FCj ), the fault cause evaluation data is based on the input data (D IN ) calculations; - based on each failure cause (FC Dj ) Calculated fault cause evaluation data (R FCj 、RUL FCj 、A FCj ), calculate (32) said failure mode evaluation data; - if said failure mode (F i ) with one or more undetermined fault causes (FC U1 ,…,FC UM ), then perform (33) a second calculation process (32) to calculate the failure mode assessment data, the failure mode assessment data based on the input data (D IN ) calculation; - calculation (4) system evaluation data (R S 、RUL S 、A S 、RSK S 、POF S ), the system assessment data is based on the failure mode assessment data (R Fi 、RUL Fi 、A Fi 、RSK Fi 、POF Fi )calculate.
Description
Technical field [0001] The present invention relates to a method for evaluating a health condition of an industrial equipment. [0002] The method according to the invention is particularly suitable for health assessment of low, medium or high voltage electrical or systems (e.g., switching devices, switching devices, Switchgear), distribution networks, etc.). Background technique [0003] For purposes of the present invention: [0004] - The term "low pressure" (LV) relates to an operating voltage of the power distribution level, the operating voltage below AC 1kV and DC 1.5kV; [0005] - The term "medium pressure" (MV) involves an operating voltage of the power distribution level, the operating voltage above AC 1kV and DC 1.5kV, up to tens of kV, such as high exchange of 72kV and DC 100kV; [0006] - The term "high pressure" (HV) relates to an operating voltage of the transmission level, the operating voltage above tens of kV, such as above the exchange of 72kV and DC 100 kV. ...
