Relay na farko da tsari
Ma'ana: Rilē na tsarin kashi shine wata rilē mai gudummawa ta hanyar tasiri na tsarin kashi daban-daban. Yana nuna wurin da ya fi sani a cikin rilē na tsarin kashi. Binciken bayan wannan rilē da sauraron rilē na tsarin kashi yana cikin inganci na coil mai hauwarta. Rilē na tsarin kashi tana da coil mai hauwarta don bincika masu lalace-ma a kan tsari a lokacin da ke faruwa masu adadin kashi mai yawa.
A cikin sassan rilē na tsarin kashi, ana haɗa coil mai hauwarta a kan wire mai sarrafa, kamar yadda aka bayyana a nan. Kashi mai haɗa suka shiga a kan current transformers (CTs) suna dole a kan coil mai hauwarta. Amma, coil mai yi ake haɗa a kan tsakiyar coil mai hauwarta.
Coil mai hauwarta tana gudummawa halayen rilē. Tana taimakawa zama ba ta kashe transformer ba saboda kashi mai lafiya. Kuma, coil mai hauwarta tana juye harmonics a kan inrush current.
Sassan Yiwa a Kan Rilē na Tsarin Kashi
Torque mai haɗa a kan coil mai hauwarta tana taimakawa ba a sake masu trip circuit, amma torque mai haɗa a kan coil mai yi tana taimakawa zuwa masu trip circuit. A lokacin da zaɓi da kusa da kai, torque mai haɗa a kan coil mai hauwarta tana fiye da torque mai haɗa a kan coil mai yi. Saboda haka, rilē tana zama a cikin yanayi ba.
Idan an faruwa a kan gida, torque mai haɗa a kan coil mai yi tana fiye da torque mai haɗa a kan coil mai hauwarta. A wannan lokaci, masu trip circuit suna zuwa, kuma suna kawo circuit breaker. Torque mai haɗa a kan coil mai hauwarta zai iya canzawa tare da gudummawa adadin turns a kan coil mai hauwarta.
Saboda taimakawa a kan coil mai hauwarta, kashi mai haɗa a kan rilē tana zama wata abu mai yawa. Kashi mai haɗa a kan coil mai yi tana mutane (I1 - I2). Saboda coil mai yi tana haɗa a kan tsakiyar coil mai hauwarta, kashi mai haɗa a kan coil mai hauwarta tana mutane (I1 + I2)/2. Idan an faruwa a kan gwamna, I1 da I2 suna zama, kuma torque mai haɗa a kan coil mai hauwarta tana zama. Wannan tana taimakawa ba rilē ba ya yi kasa.
Halayen Yiwa a Kan Rilē na Tsarin Kashi
Halayen yiwa a kan rilē na tsarin kashi tana bayyana a nan. Chart tana nuna cewa ratio na operating current zuwa restraining current tana zama a cikin tsari mai yawa. Wannan wata rilē tana da sunan biased differential relay. Saboda, coil mai hauwarta tana da sunan bias coil, saboda tana haɗa magnetic flux, wanda tana taimakawa yiwa a kan rilē.
Abubuwan Rilē na Tsarin Kashi
Rilē na tsarin kashi tana da biyu na abubuwan, kamar:
Wannan rilē suna amfani a cikin muhimman electrical components kamar generators, transformers, feeders, transmission lines, kuma wasu.
1. Amfani a Cikin Sassan Uku-Terminal
Wannan wata rilē na tsarin kashi tana iya amfani a cikin electrical elements da suka da terminals da su duka biyu. A cikin sassan uku, har terminal tana haɗa a kan coil da adadin turns. Torques mai haɗa a kan coils suna yi waɗansu da ba su ji koyarwa, kuma suka haɗa arithmetically.
Tsari mai haɗa a kan rilē tana yawan haɗa saboda distribution na kashi a cikin coils mai hauwarta. Wannan rilē suna daƙe yiwa a lokacin da kasa ko a lokacin da suka yi a matsayin high speeds, tare da taimakawa yi aiki da kasa a lokacin da zaɓi.
2. Rilē na Induction-Type Biased Differential
Rilē na induction-type biased differential tana da disc mai haɗa a kan air gaps na electromagnets biyu. Copper ring tana haɗa a kan pole, kuma ring tana iya haɗa zuwa, a kan, ko karfin pole. Wannan sassan mechanical tana taimakawa yiwa a kan rilē, tare da taimakawa tafi fadada a kan electrical quantities da kuma yi aiki a lokacin da ya shafi.
Disc tana haɗa a kan biyu na torques, torque mai haɗa a kan element mai yi da torque mai haɗa a kan element mai hauwarta. Idan shading rings na biyu suka haɗa a kan yadda ake haɗa, torque mai haɗa a kan ring tana zama zero. Amma, idan shading ring na element mai hauwarta tana haɗa zuwa iron core, torque mai haɗa a kan element mai hauwarta tana fiye da torque mai haɗa a kan element mai yi.
