Ballast Na'Iko: Tsarin Haɗa da Zuwan Kula
Mai wa Ballast Daɗi?
Ballast daɗi (ko ballast daɗi) shine wurin da take kula tsarin hanyar daɗi da kuma yadda ita ce ta hanyoyin magana.
Take ya yi wannan a kan alaka da hanyar daɗi. Ballast daɗi zai canza tsari na daɗi zuwa tsari mai yawa don kula hanyar daɗi a Lambu Daɗi – tare da kula tsari a kan lambu da daɗi a kan lambu.
Amfani da Ballast Daɗi
Akwai abubuwa masu kyau a amfani da ballast daɗi a cikin ballast daɗi na electromagnetic.
Take ya yi a kan daɗi mai yawa.daɗi. Take ya bazu tsari mai yawa don kula hanyar daɗi a kan daɗi.
Take ya yi inganci da ke ci gaba a lokacin da take yi aiki.
Babu effect ko RF interference.
Saboda take ya yi a kan daɗi mai yawa, take ya taimaka wajen kula hanyar daɗi daidai.
Babu starter da ke amfani a cikin ballast daɗi na electromagnetic.
Babu flickering.
Babu vibration da ke faru a lokacin da take bazu.
Zane ya fi girma.
Ballast loss ya fi yawa. Saboda haka, za a iya haɓaka energy.
Take ya nuna ƙaramin ranar da Lambu ke ƙara.
Saboda aiki a kan daɗi mai yawa, hanyar daɗi a kan lambu daɗi ya fi yawa. Saboda haka, mutanen lambu ya fi yawa.
Alaka da Ballast Daɗi
Ballast daɗi ya samu supply a 50 – 60 Hz. Tana bazu AC voltage zuwa DC voltage. Kadan, tana filtra wannan DC voltage tare da amfani da capacitor configuration. Duk da cewa filtered DC voltage an sanar zuwa high-frequency oscillation stage inda oscillation na square wave da frequency range su ne 20 kHz zuwa 80 kHz.
Saboda haka, output current ya fi yawa. A small amount of inductance an sanar don taimaka da rate of change of current a kan high frequency don bazu value mai yawa.
Gaskiya, ana buƙata 400 V na biyu don kula hanyar daɗi a kan fluorescent tube light. Idan switch ya shiga, initial voltage across the lamp ya zama 1000 V saboda value mai yawa, saboda haka, hanyar daɗi ya faru daidai.
Idan hanyar daɗi ya faru, voltage across the lamp ya rage zuwa 230V zuwa 125V, kuma ballast daɗi ya ba da daɗi da ke ɗauke a kan lambu.
Kula voltage da daɗi na wannan shine mafi girma na ballast daɗi. A lokacin da fluorescent lamps ke aiki, ballast daɗi ya taimaka wajen haɓaka daɗi da voltage.
Al'adun Basic Circuitry na Ballast Daɗi
A yanzu, design na ballast daɗi ya fi yawa da ya fi yawa da ya fi yawa da ya fi yawa. Komponantoci basic da ake amfani a cikin Ballast Daɗi suna cikin kasa.
EMI filter: Blocks any electromagnetic Interference
Rectifier: Converts AC power to DC power
PFC: It does Power Factor Correction
Half-Bridge Resonant Output: Converts DC to square waved voltage with high frequency (20 kHz to 80 kHz).
Control Circuit: Controls voltage and current across and through the lamp respectively.
Mai wa Ballast HID?
Ballast HID (HID stands for High-Intensity Discharge) shine wurin da ake amfani don kula voltage da arc current na High-Intensity Discharge lamps a lokacin da suke aiki. Circuit diagram na ballast HID daban-daban ana bayyana a kan kasa.
Abubuwan Ballast HID
Ballast HID zai iya kula a ƙasashe daban-daban:
Reactor ballast
Lag ballast
Regulator ballast
Auto regulator ballast
Bayanai na kowane ƙasa ana bayyana a kan kasa.
Reactor Ballast
Wannan reactor ballast shine wire coil a iron core wanda ake sanya series da lambu.
A capacitor an sanar don kula power factor da kuma capacitor ya kamata a kan line.
Voltage change a kan lambu saboda reactor shine 18%, wattage 5% change da kuma 5% line voltage change.
Take ya kula voltage na lambu daidai, amma take ya kula line voltage daidai.
Reactor ballast ya bazu low current crest factor na about 1.5.
Limitation na starting voltage da take zai iya bazu lambu shine line voltage.
Regulator ballast ana bayyana a kan kasa.
Lag Ballast
A combination of an autotransformer and a reactor forms lag ballast.
This lag ballast has the same regulation characteristics as the reactor ballast.
But lag ballast overcomes the starting voltage limitation, i.e. more than line voltage.
It is bulk in size with a greater loss.
A lag ballast cost higher.
A circuit diagram of a lag ballast is shown below.
