The Kinds Of HV Relay And Their Relevance

By Linda Moore


Relays are machine switching apparatus that are used for activating a network or system with a remote signal. This takes out the need to manually handle high voltage setups usually associated with electrical cabling or wiring. These setups are highly insulated and these are often set in media that have greater dielectric values, like transformer oil, high vacuum environments and such.

Specialist companies provide industries with relays that have been engineered and tested to exacting specifications. The HV relay is a small but highly important unit that makes industries run with large scale processes, and the qualities are very demanding because of the workloads involved. You can research about these online and get comparative values.

The switches in use are of several types. The single pole, single throw type is one that comes in normally closed and normally open classes. It is the relay that companies use for direct applications, easy to operate with off and on functions found in basic kinds of usage for it.

SPDT is something with both on and of options, technically this means single pole double throw, with closing and opening options in one relay. The continuity provide by this is something that is important to operating a system of relays under one control bank. This type of large scale switching apparatus can control industrial production and complex networks of lines for electric or telecom companies.

The double pole or double throw relay or the DPDT contains two double throw relays. These units can compartmentalize any part of a production process or electrical network. This means that a factory, say turn on or shut off one part of its operations for servicing or repair while other processes are still running to complete the complex set.

The relays in question will compartmentalize a very long process. For example, a utility network needs to turn off one part of its operations so that some glitches can be repaired. The DPDT enables engineers and worker to switch off this part while the rest of the network still operates so service to consumers is continuous.

The latching relay is also called the bistable switch and is also applied to continue an operation. Failsafes are set with other types of switches, so they must always be coil charged in order to keep on working, but the latching switch only needs a single short pulse to work. The control system will be able to thus operate other necessary processes when an operation is on or off.

Contactors are placed strategically through a switching system. They provide normal throughputs a way to handle great charges of electrical pulses of up to 1500V. Thus, an industrial process can operate at very high capacities through contactor switches without fear of fuses and relays burning out and halting operations.

Relays and contactors come in many different kinds of voltage capacities, sizes and shapes to provide stability and safe operational procedures for industrial applications that need high voltage pulses. Each one is configured to address specific processes or volume distribution for all kinds of applications. Getting to know them requires that you know your specifications or switching needs.
