According to embodiments of the present disclosure, there is provided an apparatus and method for protecting a solid-state circuit breaker. The apparatus comprises: a temperature detection unit configured to detect a case temperature of each transient voltage suppressor in one or more transient voltage suppressors; and a control unit configured to: receive the case temperature of one or more transient voltage suppressors from the temperature detection unit; for each of the one or more transient voltage suppressors, predict a junction temperature of each of the one or more transient voltage suppressors after the first switching device and the second switching device are switched from an on state to an off state, based on the case temperature before the first switching device and the second switching device are switched from the on state to the off state; and in response to the junction temperature of at least one transient voltage suppressor of the one or more transient voltage suppressors exceeding a predetermined temperature threshold, generate a first alarm signal.
An apparatus for protecting a solid-state circuit breaker, the solid-state circuit breaker comprising a first switching device, a second switching device, and a first transient voltage suppression unit, the first switching device being connected in series with the second switching device, both the first switching device and the second switching device being connected in parallel with the first transient voltage suppression unit, the first transient voltage suppression unit comprising one or more transient voltage suppressors, the apparatus comprising:
A method for protecting a solid-state circuit breaker, the solid-state circuit breaker comprising a first switching device, a second switching device, and a first transient voltage suppression unit, the first switching device being connected in series with the second switching device, both the first switching device and the second switching device being connected in parallel with the first transient voltage suppression unit, the first transient voltage suppression unit comprising one or more transient voltage suppressors, the method comprising:
