MTBF,Mean Time Between Failures. MLVS, Main Low Voltage Switchboard.
When you take a look inside the switchboard, you will see a bank of busbars.The busbars, which are generally bare and supported by insulators, are wide strips of copper that connect to switchgear. It also has gauges that show the frequency and synchroscope.It is important that the amount of electric power that goes into the switchboard is equal to the electric power going. Such switches are fed from a generator which has AC frequency and load sharing controls. The switches in the board control the amount of current that goes into the switchboard. Each panel contains switches to allow electricity to be redirected.With a switchboard, a technician is protected from possible electrocution. It is composed of an assembly of panels.
Switchgear can also be used as a circuit breaker.There are many different types of circuit breaker switchgear. Be ready with your protective equipment such as thick rubber mats and gloves, when working with an open switchboard.Switchboards are isolated and protected with other equipment including substations, motors, high or medium voltage distribution networks and transformers.Switchgear are also essential a type of electrical distribution device that is used to convert incoming electrical power into several smaller voltages. When working on live switchboards, precautionary measures are crucial. These active busbars are a deadly source of power.
The open air switchgear circuit breakers use compressed air to blow out the arc. Oil insulated switchgear depend on an oil vaporization blast through its arc.The gas insulated switchgear stretches the arc with a magnetic field and also depends on the dielectric strength of the gas to quench the stretched arc. It also clears faults downstream and comes in varied parameters, which include number of panels, electrical specifications and mounting style.The common types of switchgear are vacuum circuit breakers, oil insulated switchgear, gas insulated switchgear, and a simple open air circuit breaker. Theyre frequently used in modern medium-voltage switchgear of up to 35,000 volts.If you need to de-energizing equipment, you can use switchgear. The arc quenches when it is stretched to less the 2 to 3 mm.
Their design is especially made for interruption of fault currents.The Classifications of switchboards are based on the current rating, the amount of interrupting rating, by voltage class, insulating medium, construction types, operating method, type of current, interrupting type, and application.
