The topology principle of DC circuit breakers is very complex. According to the different key breaking devices in DC circuit breakers, they can be divided into three types: mechanical DC circuit breakers, all solid-state DC circuit breakers, and hybrid DC circuit breakers that combine mechanical switches and solid-state switches. The different structures and working principles of these DC circuit breakers can be applied to different DC circuits to achieve reliable circuit protection and switch control.
There are two main wiring methods for DC circuit breakers: backboard wiring and plug-in wiring. The advantage of backboard wiring is that when maintaining DC circuit breakers, only the front power supply needs to be disconnected without the need for rewiring. However, this type of structure is quite special and needs to be installed according to the manufacturer's requirements to avoid affecting the normal use of the circuit breaker. The advantage of plug-in wiring is that it is more convenient. When the circuit breaker needs to be replaced, simply unplug the old circuit breaker and replace it with a new one. When installing using this method, ensure that the plug is securely fastened to reduce contact resistance and improve safety and reliability.
