Common Usages Of High Voltage Contactor

By William McDonald


Electrical components carry current that needs to be controlled regularly. For this reason, there ought to be components connected to devices transmitting electricity. Markedly, a high voltage contactor is used to regulate current by allowing devices to be switched on and off. Various devices that must have fuses are explained in the paragraphs 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.

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.

Another usage is in mercury-wetted relays. These are transmitters whereby valves are first moistened with mercury before use. However, they may not be categorized as contacts due to the amount of voltage used. Normally, they operate on currents below 15 amperes, unlike other circuits.

Another usage is in camshafts also known as transformers. Camshafts are special transmitters that utilize numerous circuits aligned sequentially. Electric magnets would be best, but they cannot be used individually. Switch efficiency in transformers is more improved since electric current may be powered by electric motors or gas cylinders. Initially, camshafts were widely used to speed up electric locomotives.

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.
