Kontaktar ana cikin electromagnetic mechanism, contact system, arc extinguishing device, da sauransu. Idan kontakin kontaktar ta ci, electromagnetic force tana ci armature da kuma tana ci main contact, saboda hakan tana kudanta jirgin; idan kontakin kontaktar ta kudeta, armature tana ci rike a kan spring, main contact tana kudeta, da kuma tana kudeta jirgin.

Wurare da ake amfani da ita

A cikin sistema na kontrola lift, an amfani da kontaktar don kontrola amfani da motor don in yi lift. A cikin sistemas na AC, an amfani da kontaktar don kontrola kudancin da kudeta abubuwan da ke da inganci kamar compressors.

Relay na hoton

Faifan

Relay na hoton yana daidaitar da overload protection ta motor. Ita tana ci a kan thermal effect ta current. Idan motor yana da overloading da rike da current yake ci, bimetal sheet tana ci da kuma tana ci. Idan ciyan yana kafa da darasi, contact tana ci, saboda hakan tana kudeta control circuit ta motor da kuma tana haifar da motor. Saboda motor yana da starting current da yake da karfi a lokacin da ita tana ci, relay na hoton tana da thermal inertia da kuma tana ci da starting current.

Wurare da ake amfani da ita

Relay na hoton an amfani da ita a cikin control circuits ta duk motors na industries, kamar motors a cikin lathe, milling machines, drilling machines, da sauransu, don in haifar da motors a cikin amfani da rike.

Current transformer da voltage transformer

Current transformer

• Muhimmanci: Yana ci current da yake da karfi a kan current da yake da ƙarin (5A ko 1A), don in iya amfani da ita a cikin measuring instruments (kamar ammeter), relay protection devices, da sauransu, don in iya amfani da ita a cikin measurement, protection, da sauransu. A cikin alternating current systems, idan an buƙata ci current da yake da ƙarin (kamar those in high-voltage transmission lines), direct measurement yana da rike da kuma yana da ƙasar, current transformers zai iya haifar da wannan abu. A cikin principle of electromagnetic induction, primary winding tana ci a kan measured circuit, da kuma secondary winding tana ci a kan measuring instrument ko protection device.

• Wurare da ake amfani da ita: An amfani da ita a cikin power system substations, power plants, da sauransu, don in iya kontrola running current ta lines da equipment.
  

Voltage transformer

• Muhimmanci: Yana ci high voltage a kan low voltage (kamar 100V) proportional, don in iya amfani da ita a cikin measuring equipment kamar voltmeter da relay protection device, don in iya amfani da ita a cikin measurement da monitoring ta voltage. Misali, a cikin high-voltage transmission line, don in iya amfani da ita a cikin voltage ta line, voltage transformer tana ci high voltage a kan low voltage da ke da muhimmanci a cikin measuring da protection device. Ita tana ci a kan principle of electromagnetic induction, da kuma primary winding tana ci a kan circuit under test, da kuma secondary winding tana ci a kan measuring equipment.

• Wurare da ake amfani da ita: Ita tana da muhimmanci a cikin measurement, monitoring, da protection ta power system.

Varistor

Faifan

Varistor yana daidaitar da nonlinear resistance element da ke da sensitivity ta voltage. A lokacin da voltage tana da ƙarin, tana da resistance da yake da ƙarin da kuma tana da ƙarin da yake da tabbacin jirgin. Idan an buƙata ci overvoltage a cikin jirgin (kamar surge voltage da ke samu da lightning strikes ko peak voltage a cikin grid), resistance value ta varistor tana ci da kuma tana ci overvoltage, don in iya haifar da following circuit equipment daga damage ta overvoltage.

Wurare da ake amfani da ita

A cikin input end ta AC power supply, kamar computer power supply, TV power supply, da sauransu, an samun varistor don in iya haifar da damage da ke samu da lightning strikes da kuma grid voltage fluctuations.

Common-mode inductance

Faifan

Common mode inductors ana amfani da ita don in iya haifar da common mode interference a cikin AC circuits. A cikin electronic equipment, saboda presence of various electromagnetic interference sources, common mode interference signals (interference signals da ke da same direction da ke da biyu ko da sauransu wires) zai samu. Common mode inductor tana da biyu windings da ke samun iron core. Idan common mode interference signal tana ci common mode inductor, magnetic field da ke samu da current a kan biyu windings tana ci da kuma tana ci large inductive reactance to common mode interference signal, don in iya haifar da ita, while normal differential mode signal (signal da ke da opposite direction a kan biyu wires) tana da ƙarin influence.

Wurare da ake amfani da ita

A cikin switching power supply, communication equipment, computer motherboard, da sauransu, an amfani da ita don in iya ci electromagnetic compatibility (EMC) ta circuit da kuma haifar da impact ta common mode interference a cikin performance ta equipment.
