Me kana wani ɗace a cikin ɗauke na gajarta da ɗauke na tushen hankali?

Za a iya tafi dacewa a kan trip speed da ke bayan Overload da Short-Circuit Protection?

Trip cikin circuit ta overload da trip cikin short-circuit sun fi dacewa sosai domin hakan yadda suke yi waɗannan kuma mafita suke gani. Wannan shi ne bayanin mai zurfi:

1. Overload Protection (Overload Protection)

Takaitaccen

Overload yana nufin yanayin da current a cikin circuit ya kawo karfin da ake sani, amma bai samu masu short circuit ba. Overload yana faruwa ne domin overcurrent da ya zama da lokaci, wanda zai iya haɓaka hoton wires, damage zuwa insulation, da sauransu.

Trip Speed

• Amsa Mai Tsabta: Overload protection ana gina don amsa mai tsabta saboda currents na overload zai iya zama da lokacin da ba sa bafore ba. Overload protectors, kamar thermal-magnetic circuit breakers, suna da mekanismi na time delay wanda yake iya haɓaka short-term overcurrents za ta dole, amma zai trip idan current ya ci gaba da karfin da ake sani a lokacin da ya kawo lokaci.

• Time-Current Characteristics: Curve na time-current (TCC) na overload protector yana nuna cewa trip time yana ƙasance a lokacin da overload current yana ƙasance, amma har yanzu yana bukata seconds da kuma minutes.

Applications

• Circuits na Gida: Circuit breakers a cikin circuits na gida suna da overload protection don haɓaka hoton da biyu.

• Equipment na Karkashin Iya: Overload protectors a cikin equipment na karkashin iya suna amfani a matsayin haɓaka motors da sauran electrical devices daga long-term overcurrent damage.

2. Short-Circuit Protection (Short-Circuit Protection)

Takaitaccen

Short Circuit yana nufin yanayin da abubuwan low-impedance connection ta shiga bayan biyu a cikin circuit, wanda yake haɓaka ƙarshen current da kuma yake ƙara jiki da normal operating current. Currents na short-circuit suna da muhimmanci da zai iya haɓaka damage mai yawa a cikin equipment, hoton da kuma explosions.

Trip Speed

• Amsa Mai Yawanci: Short-circuit protection ana gina don amsa mai yawanci saboda currents na short-circuit suna da muhimmanci da zai iya haɓaka damage mai yawa a lokacin da yawan lokaci. Short-circuit protectors, kamar instantaneous circuit breakers, suna da design don trip a lokacin da milliseconds, don kudan current da yawa.

• Instantaneous Tripping: Curve na time-current na short-circuit protector yana nuna cewa device zai trip da yawa idan current ya kawo karfin da ake sani, ba a da time delay ba.

Applications

• Circuits na Gida: Circuit breakers a cikin circuits na gida suna da short-circuit protection don haɓaka hoton da biyu da kuma damage da equipment da ke faruwa saboda short circuits.

• Equipment na Karkashin Iya: Short-circuit protectors a cikin equipment na karkashin iya suna amfani a matsayin haɓaka complex electrical systems daga damage mai yawa saboda short circuits.

Summary

• Overload Protection: Ana gina don amsa mai tsabta, ta haɓaka short-term overcurrents za ta dole amma zai trip idan current ya ci gaba da karfin da ake sani a lokacin da ya kawo lokaci. Har yanzu yana bukata seconds da kuma minutes.

• Short-Circuit Protection: Ana gina don amsa mai yawanci, trip a lokacin da milliseconds don kudan current da yawa da kuma haɓaka damage mai yawa a lokacin da yawan lokaci.

Fahimtarsa da dacewar speed da ke bayan wannan labaran protection mechanisms yana taimakawa wajen gina da kuma haɓaka circuits don haɓaka safe da reliable operation su.
