Din daɗi na ƙarfin yadda ake amfani da potentiometers kafin resistors don rarraba hanyoyi a makarantun nuna?

Potentiometers da kuma resistors suna cikin kayayyaki na iya amfani da su don haɗa tsari ko voltage a cikin circuit, amma sun yi a hanyar bambanta da tushen bayanai. A cikin power stations da wasu abubuwa masu amfani game da voltage, yana da kyau a kan amfani da potentiometers mafi yawan resistors na musamman don haɗa voltage

• Tunability: Potentiometer yana ba mai amfani da shi aiki a zama ya yi haɗa tsari a cikin fadin batu, wanda yake taimaka waɗannan a yi gaba-gaban da voltage ko current a cikin circuit. Duk da haka, tsarin resistors na musamman yana da tsari na musamman.

• Flexibility: Aiki na haɗa da ke samu da potentiometer yana ba operator aiki a zama ya yi haɗa parametoroji a cikin circuit a baya-bayan idan an bukata, wanda yana da muhimmanci a cikin abubuwa masu amfani da voltage na haɗa.

• Cost savings: A cikin wasu batu, amfani da potentiometer ta da haɗa a kan haɗa voltage yana iya baƙe aiki a kan amfani da kungiyoyi na resistors na musamman don samun aiki, wanda yana iya haifar da cost na gaba-gaba.

• Simplified circuit design: Amfani da potentiometers yana iya haifar da tsarin circuit, saboda ba a tabbas ba a canza resistors na musamman don haɗa operating point na circuit.

• Easy commissioning: A cikin lokacin da ake yi development ko commissioning, potentiometers yana ba engineers aiki a zama ya yi haɗa parametoroji a cikin circuit a baya-bayan idan an bukata, ba a tabbas ba a canza hardware components.

Amma, yana da kyau a nuna cewa a cikin power system mai yawa kamar power station, yana da wani batu a canza voltage tun daga potentiometer na haɗa, saboda fadin adjustment range da accuracy yana da yawa da yin aiki a kan potentiometers na musamman. A cikin abubuwa masu amfani, voltage regulation na power stations ana samun a hanyar automatic control systems, wadannan suna iya kasance automatic voltage regulators, power electronics (kamar static inverters ko inverters), etc.

Duk da haka, potentiometer na da batutuwar, misali, ba ta daidai da yake da amfani a cikin high-power environments, saboda contact points na yana da yawa a faruwa da kuma lafiya. Saboda haka, a cikin abubuwa masu amfani, zaɓi na component na da take yi haɗa voltage yana da kyau a duba muhimmin requirements na application scenario, kamar power level, adjustment accuracy, reliability da cost.
