Devices That Use 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.

In huge buildings such as business premises and office apartments, it is common for a large amount of electric power to be used up. In such cases, connectors are used in paneling lighting. This enables power to be controlled from one specific point. Additionally, those valves efficiently supply large currents to such buildings. Latching switches are preferred in big buildings since coils consume a lot of electric energy in those applications.

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.

Mercury transmitters also utilize connectors. Electric signals in such devices are moved through liquefied mercury. Since mercury reacts easily with air, it is contained in an airtight container. Containers are further lined with insulation materials to prevent heating. For this reason, cycling surfaces which easily corrode with time may utilize such valves. However, usage of mercury relays is reducing since mercury is not environmental friendly. Solid connectors are used in place of these.

A different version of mercury transmitters is mercury wetted relays. These minimize the amount of liquefied mercury infuses. Unlike in mercury relays, valves are coated with a little mercury before use. For this reason, they cannot relay greater capacities compared to other connectors. As a matter of fact, their carrying capacity is limited to 15 amps and below.

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.
