Embodiment Construction

[0038] Any feature disclosed in this specification, unless specifically stated, can be replaced by other alternative features that are equivalent or have similar purposes. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features. In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] The life monitoring detection of low-voltage circuit breakers and their control units is affected by the following factors:

[0040] The number of circuit breaker operations (including opening and closing and tripping), as well as the magnitude and duration of interrupted current under each operating condition; operating temper...

Abstract

The invention provides a method for analyzing the service life aging of a circuit breaker, and relates to the field of electrical element operation performance. The method comprises the following steps: judging the operation aging of the circuit breaker; calculating the environmental aging of the circuit breaker; calculating thermal aging of a control unit of the circuit breaker; calculating corrosion aging of the control unit of the circuit breaker; calculating the environmental aging of the control unit of the circuit breaker. According to the method for calculating the aging value of a circuit breaker, the aging value of the circuit breaker is calculated by comprehensively considering the operation state of the corresponding circuit breaker according to the temperature, humidity, salt mist environment and / or corrosive gas of the environment, subsequent replacement of an aged circuit device is facilitated, the failure rate of equipment is reduced, and the reliability is improved.

Description

technical field [0001] The invention relates to the field of operating performance of electrical components, in particular to a method for analyzing the life aging of a circuit breaker. Background technique [0002] The aging analysis of circuit breaker life is a statistical analysis model based on the operation of a large number of on-site equipment. As with any statistical model, aging predictions are not strictly accurate 100% of the time. It provides an estimate of the probability of failure due to aging. If a device ages to 100%, it does not mean that the device will fail immediately, but that the probability of failure of the device is very high, and the risk of failure will be high. Contents of the invention [0003] The technical problem to be solved by the present invention is: how to predict the operating state of the circuit breaker in advance, replace the old circuit breaker in time, and reduce the failure probability of the equipment. [0004] A method for ...
