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.
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.
Next, contacts are used in vacuum switches. Such is designed to use vacuity bottles condensed valves for arc suppression. Suppression of arcs reduces contact size hence consume less space during excess currents. Encapsulation allows similar valves to be used in dirty environments like mining. Similarly, they may be used in numerous applications with medium currents of about 1000 to 5000 volts since they can efficiently displace circuit breakers filled with oil. These type of switches can only be used with alternating current. Therefore vacuum connectors can effectively be used to disrupt electric arc power as well as where quick lighting is necessary.
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.
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.
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.
