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.
Before understanding where connectors are placed, it is important to know various components are making it up. First, there is a coil. These are necessary for energizing valves to turn contacts on or off. Another component is the pole. This part carries current. Finally, there are auxiliary contacts. This controls as well as signals applications of circuits.
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.
Thirdly, connectors are a common element of mercury relays. Mercury transmitters utilize liquid mercury in transmitting electric current. They are unique since mercury is stored in a properly sealed bottled with insulated inner surfaces. Insulation makes such contacts suitable for cycling surfaces which are prone to corrosion. These transmitters are however being discouraged because mercury is known to be environmentally hazardous.
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.
