LT switcher is a safety panel consisting of a number of disconnect-switches that turns on and off the motors, transformers or other electrical appliances. It can be regarded as a power source in the building and production houses, which supply and check the flow of electricity and even protect the circuit from wear and tear.
Circuit Breakers
Circuit breaker disrupts a circuit when any fault occurs in an electric subsystem. It safeguards an electric circuit in the case of short circuits and overloads. These devices play a key role in switchgear installations as the electrical engineers can easily approach the circuit after fixing the possible fault.
Disconnect Switches
Disconnect switches are generally used to detach electric power supplies and loads in case of fault or when a system need to undergo the maintenance process. Unfortunately, it is not capable of switching currents. They are used as safety components in switchgear assembly. This helps the technicians to detect faults in the circuit and assure that it is disconnected from power. These switches are attached to locks to fasten them and ensure that the electrical circuit is free from voltage and is safe too.
Load Break Switches
Load break switches are not really meant to break up short circuit but instead change the loads on or off. These devices are mainly employed at production houses for disconnecting the loads manually or at substations in order to attach power lines with transformers. Load break switches are cost effective way of using electrical switches at houses or industries.
Contractors
Contractors are used in the case when switchgear needs to turn the loads on or off multiple times. The LT switchgear handling such components use heavy contacts that are associated with load capable of handling several switching cycles. The operator stimulates magnetic coil as the contacts move on and hence a circuit is closed.
Fuses
Fuses are highly cost-effective as compared to circuit breakers and used with non-critical switchgear applications that perform the same functionality. The main function of a switch is to disconnect the flow of electricity in the circuit and often use fuses for it. When the fuse blows due to access electricity flow, the technicians unbolt the switch to know the possible faults. After mending it, the fuses are replaced in its position for smooth distribution of electricity.
Enclosures
Electrical appliances are very useful but due to heavy currents and voltages, it is pretty dangerous if not handled carefully. Signboards and fences can work well if the switchgear is developed for outdoor applications. Metal cabinets and enclosures are used in the cases of heavy industrial or commercial applications as it forbid technical staff and public from touching those live appliances that can cause great harm or even take the lives of many. Several safety enclosures are employed when LT switchgear is developed for indoor applications.
Summary
LT Switchgear holds a number of disconnect switches used in buildings or production houses as a power source and capable of turning on or off when required. It is used to render and control power; and even prevent the system from various unfavorable conditions to ensure smooth performance.
