Applications Of High Voltage Contactor

By William McDonald


Electrical circuits are started as well as cut off by valves built in electrical devices. Such components vary in the amount of current they can withstand. There are low versus strong power fuses. Notably, a high voltage contactor is widely used for controlling extremely great currents. Numerous devices use this and a few are discussed below.

Connectors have a number of applications. It is paramount to first understand the features of valves before delving into these applications. Contacts have three components. Each of these is designed to perform differently. The first part is known as a coil. Coils are used to power switches on or off. They are coiled to help pass current fast as well as cut it off. Secondly, there is a pole. Poles are suited for transmitting current. Then there are auxiliaries which panel and signals circuit usage.

The first application point is in lighting control. Bigger lighting connections are done in offices, or merchandising buildings require connectors that can withstand great power. Such is sustained by these contacts. They are designed to have two working coils. One is temporarily energized to close connections in valves while the other is used to open switches. Latching strong current connectors are used to prevent a lot of power consumption in the opening and closing coils.

Great current connectors are also used in vacuum contacts. Vacuum connectors are switches which make use of valves compressed in void bottles. These allow suppression of arcs which in turn pushes valves to a smaller size. For this reason, those fuses can be used in dirty processes such as mining. Additionally, vacuum valves are preferred in applications which utilize relatively strong electric energy. This is because they displace oil-filled circuit breakers easily.

Another application of these valves is in mercury relay. Mercury displacement transmitter uses liquid mercury. This substance is contained in an insulated bottle which is completely sealed. This acts as the powering agent. Notably, one feature of such transmitters is that they prevent corrosion in components used in cycling. However, mercury is not eco-friendly. Thus those transmitters are quickly being displaced with non-mercury great current switches.

Mercury wetted transmitters are another version of mercury controlled switches. However, instead of immersion, contacts are smeared with mercury before being used. Unlike any other great current circuits, this is considered low power. This is because they only operate on strengths below 15 amperes. Other valves operate in higher rechargeable currents.

Besides the aforementioned applications, contacts are widely used in transformers. Camshafts require a number of fuses to be arranged and used in a sequential manner. Standalone rechargeable magnets are not best suited for such arrangements. Contacts are more efficient since camshafts are controlled by electric engines or gas cylinders. Motor-driven transformers were preferred in plug-in locomotives since they could easily be speed up. They are also used in internally burning locomotives used to control poppet regulators.

These components are used in magnetic starters. These are devices for energizing electricity driven motors to move. Valves are important in such devices since they not only limit the amount of power passing through but also protect the circuit from overloading. In case of power outage, they offer automatic cut-off.
