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.

Companies that specialize in providing these relays provide excellent product qualities because of their engineering, testing and application sets. The HV relay is very important to industry, with large scale uses and applications, and the standards are demanding and exacting. You can track the various kinds of these gadgets through online sites and compare the types in use.

Here are the relevant types of switches that are commonly used. The first type is also the simplest, known as the single pole single throw switch with normally closed or open kinds. The switching in question offers the most direct system found in many applications, which is the simply use of off and on.

The thing called SPDT, or single pole double throw configures both close and open applications in one relay. Because it can offer continuity, this type is relevant to arrays of switches that can control large scale use. Heavy industry, factory operations, arrays for telecom and internet connections, and energy or utility companies all use it.

The DPDT or double pole double throw system is something used for systems that need constant switching. It has two double throw units operating in the relay and thus provides on and off qualities hermetic to its operation, only applicable to one part of a system. This is also used in large production or networked facilities.

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.

Latching or bistable switches are also useful for continuous operations. When all other types of items have failsafes that require them to have continuous coil power for the switch to be at the on configuration, the bistable system needs only a momentary pulse. This means that monitoring and control can turn this switch on or off as needed when it needs supplementary processes.

These also work with contactor switches for controlling high inrushes or overloads. These can range from 100Vdc to 1000V switching, so that normal relays will not overheat and blow up. They are the regulators that enable a system to work at maximum capacity without slowing down or having relay problems related to overloads in the system when in operation.

Contactors and relays are all available for many kinds of capacities, shapes and sizes for securing and stabilizing high voltage networks. Any specific kind is made to handle specified work sets through a distribution and switching network. You have to be knowledgeable about specs for your needs and requirements.
