Devices That Use High Voltage Contactor

By William McDonald


Specific areas require a specific amount of electric current to operate. For example, to light a large building with numerous rooms, one will need electricity devices which can handle great currents. In similar situations, high voltage contactor must be fitted in such devices. Huge power connectors are turned on and off electronically. The paragraphs below outlines various devices that utilize such.

Three elements work together to allow full functioning of fuses. These components are a coil, pole, and auxiliary. To start with, valves are switched on and off by coils. They are spiraled to reduce the distance traveled by signals, hence allow faster action. Poles transmit power signals to fuses. Finally, auxiliaries are used for paneling as well as indicating circuit application.

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.

The other usage is in vacuum contacts. These are specialized switches whose valves are compressed in vacuum containers. During transmission, these valves are pushed by suppressing arcs. They become smaller hence occupy little space than before. This makes it possible to transmit huge currents at the same time. Since switches are internal and need no air, vacuum switches can be used in dirty surroundings such as in mining. This is because they can easily move circuit breakers immersed in oil. Likewise, electric signals are easily broken hence applicable in fast lighting elements.

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.

Next usage is in transformers also known as the camshaft. Sometimes, several contacts may be used sequentially. In such cases, single electromagnets are ineffective thus the need for the camshaft. These camshafts are operated by a power-driven motor or air-filled cylinders. Initially, camshafts were vital in speeding up power-controlled locomotives. Additionally, they are applied in inner combustion machines which are used to control poppet valves.

Connectors may also be used in magnetic starters. These devices are important in starting electric locomotives. Valves are used to control the amount of energy transferred through coils. At any given time, contacts may not overload. For this reason, they are best for the provision of automatic circuit breaking.
