Abstract

An embodiment of the invention provides a method for detecting a service life of a bus capacitor and an apparatus thereof and relates to the electronic technology field. Accuracy of estimating a residual life of the bus capacitor can be increased and an accurate and effective reference can be provided for equipment maintenance and capacitor replacement. The scheme comprises the following steps of collecting a condition parameter of the bus capacitor at a current moment; according to the condition parameter of the current moment and a preset corresponding relation, acquiring a total service life of the bus capacitor under the condition parameter of the current moment; and calculating a residual life value of the bus capacitor at the current moment under a standard condition. The method and the apparatus are used for detecting the service life of the bus capacitor.

Description

technical field

[0001] The present application relates to the field of electronic technology, in particular to a method and device for detecting the life span of a bus capacitor. Background technique

[0002] In switching power supply equipment, the bus capacitor is a vulnerable part, and the failure of the bus capacitor will lead to major accidents in the power system. Therefore, knowing the service life of the bus capacitor accurately and maintaining and replacing it in time can avoid losses as much as possible.

[0003] At present, the switching power supply sold in the market, taking the uninterruptible power system (full name in English: uninterruptable Power System, UPS) product as an example, the life of the bus capacitor is usually obtained by the countdown method and the capacitance value calculation method of the bus capacitor.

[0004] The bus capacitor life countdown method is to test the bus capacitor under the worst working condition of the product to get the ...
