Muhimmin AC motor starter

Starter na AC motor shine tauri da ake amfani da ita don kawo karfi AC motor, kuma muhimmin cikin shi sun hada da wasu abubuwa masu muhimmanci:

1. Muhimmin Electromagnetic

Muhimmin electromagnetic sun hada da mafi yawan cikin muhimmin AC motor starter. Sun amfani da siffar electromagnetic don kofin da kuka kan starter da motor. Idan an kofin da starter ta hanyar zabe, akwai kisan gaji ya zo ne a ciki da ke tsara magnetic field. Wannan magnetic field ya kula iron core a cikin starter, wanda ya haifar da ita zuwa yankin. Zukan iron core ya haifar da mechanical switch a cikin starter zuwa yankin, wanda ya kofin da zabe zuwa ciki na motor da kuma ya ba motor lalacewar da ita.

2. Control Circuit

Control circuit ana amfani da ita don inganta da kafin motor. Idan an bukata don kawo karfi motor, control circuit zai taka signal na kawo karfi zuwa starter, wanda zai kofin da zabe da kuma ya kawo karfi motor. Idan an bukata don kafin motor, control circuit zai taka signal na kafin zuwa starter, wanda zai kafin da zabe da kuma ya kafin motor.

3. Main Contactor

Main contactor ana amfani da ita don inganta da kafin motor, kuma shi ne maimaita daga cikin muhimmin starter. Ya kofin da zabe idan an kawo karfi motor, da kuma ya kafin da zabe idan an kafin motor.

4. Thermal relay

Thermal relay ana amfani da ita don inganta electric motors daga hasare da ke faruwa da overloads da short circuits. Idan kisan gaji mai 1.2 darasi da rated current ya zo ne, thermal relay zai iya trip automatically da kuma kafin da zabe a lokacin da 20 minutes.

5. Button Switch

Button switch ana amfani da ita don inganta manual motor na kawo karfi, kafin, da kuma inganta direction. Ta hanyar amfani button switch, za a iya samun remote control na motor.

6. Auxiliary Components

Auxiliary components sun hada da filters da contactors. Filters ana amfani da su don kafa electromagnetic interference wanda ke faru a lokacin da motor ya yi aiki, tare da tabbacin aiki na motor. Contactors, na'am, sun amfani da su don inganta direction na motor, tare da kudaden forward da reverse functions.

7. Autotransformer (Autotransformer Voltage Reduction Starter)

Autotransformers ana amfani da su don reduced voltage starting, inda autotransformer ya amfani da su don kafin voltage don infrequent starting na electric motors. Autotransformer voltage reduction starters suna da overload protection, wanda zai iya trip automatically da kuma kafin da zabe a lokacin da 20 minutes idan kisan gaji ya zo mai 1.2 darasi da rated current.

8. Time Relay (Star-Delta Starter)

Time relay ana amfani da ita a star-delta starter don samun reduced voltage starting tare da kudaden connection mode na stator winding. Star-delta starter yana daidaita low-voltage cage-type motors da delta winding a lokacin da aiki na yau da six output terminals.

Wadannan ne muhimmin cikin AC motor starter, da kuma waɗannan muhimmiyar suka yi aiki tare da kudaden inganta cewa motor zai iya kawo karfi da kuma yi aiki da dalilai da tattalin arziki.
