Principle of Energy Storage Switch | Nader Circuit Breaker

The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the segmentation fault has a large current (excessive current will melt the

Is a bidirectional insulated-gate bipolar breaker suitable for low-voltage DC networks?

What are the operating characteristics of IGBT breaker?

The operating characteristics of this breaker are based on changes in the circuit current and terminal voltage of IGBTs. It detects the abrupt change of the terminal voltage as an abnormal condition and isolates the faulted branch in a short time to prevent the operation disturbance in the healthy part of the network.

What are the different types of circuit breakers?

When faults occur, the current which flows through the related branch diverges from the normal value. Usually, five types of protection devices, such as mechanical breakers (Molded-Case Circuit Breakers (MCCB) and Miniature Circuit-Breakers (MCB)), fuses, SSCB, and the hybrid SSCB have been used for DC fault interruptions.
