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 ...
