CIRCUIT BREAKERS
Abstract:
A circuit breaker is an automatically-operated electrical switch which is designed to protect an electrical circuit from damage caused by overload or short circuit.
Used to prevent the heavy current from damaging power system components.
Unlike fuses, normal operation can be resumed with minimal turn around time.

SION Vacuum Circuit-Breaker For Standard Applications


SION Vacuum Circuit-Breaker - OEM Package 3. Product Features


Product Features


The slide-in module contains all necessary components for the circuit-breaker compartment of a panel.
Signals for the service and disconnected positions are transmitted to the module connector at the low-voltage interface of the vacuum circuit-breaker via the position switches of the drawout element.

Vacuum circuit breakers are circuit breakers which are used to protect medium and high voltage circuits from dangerous electrical situations. In a vacuum circuit breaker, two electrical contacts are enclosed in a vacuum. One of the contacts is fixed, and one of the contacts is movable. When the circuit breaker detects a dangerous situation, the movable contact pulls away from the fixed contact, interrupting the current. Because the contacts are in a vacuum, arcing between the contacts is suppressed, ensuring ....etc

INTROUCTION



ESSENTIAL QUALITIES OF HV CIRCUIT BREAKER

High-voltage circuit breaker play an important role in transmission and distribution systems. They must clear faults and isolate faulted sections rapidly and reliably. In-short they must possess the following qualities.

In closed position they are good conductors.
In open position they are excellent insulators.
They can close a shorted circuit quickly and safely without unacceptable contact erosion.
They can interrupt a rated short-circuit current or lower current qui ....etc

INTROUCTION



New maintenance techniques and methodologies are emerging, while the circuit breakers keep improving in their designs and functions . As an example, some new circuit breakers have embedded monitoring instruments available to measure the coil current profiles and the operation timing . The recorded information can be used to monitor the condition of breakers during each operation. In this case, it may be more appropriate to replace the time-directed maintenance by condition-directed maintenance practice . When applied properly ....etc
