Industrial switchgears have been in use ever since electricity was discovered. A Switchgear is an equipment used to control and protect any type of Electrical equipment. It usually consists of a set of fuses or electrical switches to isolate the electrical circuit when required. These are mainly used to switch off equipment safely to work with them or upgrade them or to repair any faults.
The major functions of Industrial Switchgears have been stated below.
- During the maintenance of different electrical components, these switchgears play an important role in distributing the load uniformly, which helps prevent any form of system wide failure.
- It is immensely useful in lessening the amount of circuit outages during maintenance or repair work in power plants.
- It can prevent further damage by making it easier to discover faults in the system.
The location of these Switchgears depend on the location of voltage applied. When the voltage is on the lower side, the switchgear might be placed in a building but if the applied voltage is more than 66 kV, then it has to be placed outdoors.
A circuit breaker is one of the primary components of a switchgear. It is necessary to interrupt fault currents and can be categorized into the following 5 types.
Air is an electrical insulator and is often used as a cheap form of insulation for circuit breakers.
It is even a better insulator than air and is often used in switchgears where medium voltage is applied.
These are based on the vaporization of some part of the oil to prevent the arc, and are one of the oldest forms of circuit breakers. The vapour is a better insulator than air.
Sulphur hexafluoride is mainly used in these circuit breakers.
These work on a combined effect of air as well as gas insulators.
Another important invention which has revolutionized the modern world is PVC-U pipes. These pipes are extremely versatile and can be used to transport even corrosive materials since they are usually resistant to such chemicals. An additional advantage is that unlike traditional metal pipes, these are free from any rust and are extremely durable.
They are mainly used to transport drinking water from one place to another, and are also used in drainage and sewage plants.
Industrial switchgears and PVC-U pipes have played an important role in modernizing our societies. One must purchase these items from trusted brand like Polycab for the best quality.
