Mai shi ne Static Relay?

Mi ce Static Relay?

Takardan: Wani relay wadanda bai da dukkan mutum-ba shi ne ana kiran static relay. A wannan ƙarin relay, a gina aiki na farko ta hanyar muhimman suka zama da cikin jirgin magana da taurari. Idan relay ya samun static elements tare da electromagnetic relay, yana iya kiran static relay. Wannan shine saboda static units suna da amfani a kan sake fahimta input da kuma sake gina aiki, sannan electromagnetic relay yana amfani a kan aiki na farko.

Muhimmanci suka zama da cikin static relay an samu a cikin takarda. Input na current transformer an haɗa a kan line na ƙarfi, sannan output shi an haɗa a kan rectifier. Rectifier ya fi tsara input signal ko haɗa a kan relaying measuring unit.

Relaying measuring unit yana da comparators, level detector, da kuma logic circuit. Output signal na relaying unit an samu idan input signal ya kai lissafin cutar. Output na relaying measuring unit yana haɗa a kan amplifier.

Amplifier yana fi tsara signal da kuma haɗa a kan output devices. Output device yana faɗa trip coil idan relay yana yi aiki. Output yana samu a kan output devices idan measurand yana da cutar mai kyau. Idan an faɗa, output device yana ba aiki na tripping a kan trip circuit.

Static relays suna jawabi musamman a kan electrical signals. Abubuwa masu inganci kamar heat, temperature, da sauransu, suna buƙata a yi rubutu zuwa analogue ko digital electrical signals idan za su amfani a kan input relay.

Fadada Static Relay

Wadannan ne fadada static relays:

• Static relays suna ɓace mafi girma. Saboda haka, burin da ake ke measuring instruments yana rage, sannan zanen kansu yana ƙare.

• Sun ba da aiki mai zurfi, tsawon rike mai tsawo, zanen kansu mai tsawo, da kuma ba su kaɗe a bangaren shiga.

• Reset time na relay yana da tsawon mai tsawo.

• Ba suna da abubuwa masu thermal storage ba.

• Relay yana fi tsara input signal, wanda yake ƙara zanen kansu.

• Yawan ƙarfafa na tripping da ba a tabbas ba yana da ƙarfin da ba a tabbas ba.

• Static relays suna iya yi aiki a ƙasashen da aka fi sani da earthquake saboda zanen kansu mai tsawo a kan shock resistance.

Kwalaye Static Relay

• Abubuwan da ake amfani a kan static relays suna da zanen kansu mai tsawo a kan electrostatic discharges. Electrostatic discharges yana nufin ƙarshen electrons da ba a tabbas ba a kan abubuwan da suka shiga. Saboda haka, za su yi ayyuka mai amfani don in ba su kaɗe a kan abubuwan da suka shiga electrostatic discharges.

• Relay yana da zanen kansu mai tsawo a kan high-voltage surges. Saboda haka, za su yi ayyuka don in ba su kaɗe a kan damage da voltage spikes.

• Aiki na relay yana da zanen kansu a kan electrical components.

• Yana da overloading capacity mai tsawo.

• Static relays suna da rahotanni mai yawa daga electromagnetic relays.

• Construction na relay yana da zanen kansu a kan surrounding interference.

Don integrated protection da monitoring systems, programmable microprocessor-controlled static relays suna da amfani.
