Smart circuit breakers realize electronic operation, change mechanical energy storage into capacitor energy storage, and change mechanical transmission into inverter directly driven by a motor, which improves the reliability of the mechanical system.
Vacuum circuit breakers, also known as VCBs, use a vacuum to extinguish the arc created when the circuit is tripped and the contacts move apart. VCBs work quickly and effectively, making them a solid choice for medium- and high-voltage systems. Below, we will delve into how VCBs work, their applications and some of their benefits and limitations.
A vacuum Circuit breaker is used in medium voltage Switchgear for performing switching operations. In Switchgear the VCB is controlled by Electromechanical or Numerical Relays. Before knowing about Vacuum Circuit breakers, first of all, we will see what the circuit breaker is
Although the physics of interruption is quite complex, the vacuum interrupter works because the arc requires a conducting path to sustain it, but within the vacuum bottle there are no gasses to ionize; therefore, for all practical purposes, there can be no conducting path and the arc cannot be sustained. Vacuum Bottle of Vacuum Circuit Breaker
However, the arc can be controlled by cooling or using media that can withstand high potential strength. Air, Oil, Vacuum, and SF6 gas are some of the quenching media used in a circuit breaker. The breaker is named based on them. They are Air Circuit Breaker (ACB), Oil Circuit Breaker (OCB), Vacuum Circuit breaker (VCB), and SF6 Circuit Breaker.
They protect the network components in case of short circuit currents which are more stress full than traditional circuit breakers. Over the last decades Vacuum Circuit Breakers (VCB) are the most preferred switching devices in the medium voltage levels up to 52 kV. More than 80% of today's new installation employs vacuum switching technology .
The Indoor VCB operating mechanism consists of a closing spring, an energy storage system, an overcurrent release, and a switching system. It can be divided into two types: manual and electric operation. The manual operating mechanism has the functions of manual energy storage, manual opening, closing, and over-current protection.
Because of the complexity of energy storage mechanism and energy storage control process of circuit breaker, power supply fluctuations, drive mechanism jams, shedding of the energy storage spring, and failure of the limit switch may occur, ultimately leading to the circuit breaker cannot complete opening and closing operation normally.
