Dalilai na Mafi Girgiza na Kirkiro Vacuum

Idan da zai wajen yadda ake gina ko kuma a yi a tsakiyar masu amfani, akwai uku na bikin da ake amfani don inganta abin da suka shiga: 1. Bincike na Nisa ga Gwargwadon Rukunin; 2. Bincike na Tsari Mai Yawa; 3. Bincike na Tsarin Tashin.

Bincike na Nisa ga Gwargwadon Rukunin

• A cikin binciken nisa ga gwargwadon rukunin, ana amfani da micro-ohmmeter zuwa gwargwadon rukuni mai fada ta vacuum interrupter (VI), kuma an kefa da ya ra'ayi. An taka wannan resultoci da kula ce da ke kula da asusun bayanai ko da misalai daban-daban na vacuum interrupter daga wata babban sauyin.

• Hakan ya tabbatar da cewa nisan gwargwadon rukuni na kowane vacuum interrupter ya kula da asusun bayanai da aka tabbatar, kuma hakan ya ba da kyau da gyarwa da inganci. A cikin taka wannan resultoci da misalai daban-daban, za a iya samun abubuwan da ba suna daidai, kuma za a iya yi nasarori a lokacin da ya danganta.

Bincike na Tsari Mai Yawa

A cikin binciken tsari mai yawa, ana amfani da tsari mai yawa zuwa gwargwadon rukuni mai fata ta vacuum interrupter (VI). Ana zama tsarin tsari har zuwa tsari mai yawa, kuma ana ra'ayi tsarin tashin. A cikin binciken fabrika, ana iya yi hakan ta hanyar AC ko DC high-potential test sets. Mafarurar sana'a suna bayar da abubuwan da dama da za su iya amfani don yi binciken tsari mai yawa zuwa gwargwadon rukuni mai fata. Daga cikin hakan, mafiya suna da DC test sets saboda hakan ya fi karfi da ya fi yawan da ya ba da shi da AC high-potential test sets.

Idan ake amfani da DC test voltage, ana iya ra'ayi tsarin tashin mai yawa daga wurin mai kyau a kan kowane rukunin, kuma hakan ya iya kasance da alamun cewa vacuum interrupter ya ci haɗin. Don in ba hakan ba, ya kamata a yi binciken zuwa vacuum interrupter a kan biyu na tsari mai yawa, kuma hakan ya ba da tsari mai yawa da tsari mai fata. Vacuum interrupter mai haɗin da aka faruwa za a iya rasu da tsarin tashin mai yawa a kan biyu na tsari mai yawa.

Interrupter mai kyau da tsari mai yawa mai kyau ya iya rasu da tsarin tashin mai yawa, amma wannan shi ne domin kowane tsari mai yawa. Interrupter da wurin mai kyau a kan rukunin ya iya rasu da tsarin tashin mai yawa ne domin idan ya ci gaba, ba idan ya ci gaba-ba. Saboda haka, a yi binciken zuwa biyu na tsari mai yawa zai iya ba da damar hakan. Tsari mai yawa da za a amfani don yi bincike zuwa vacuum interrupter ya kamata a yi kula da asusun bayanai na vacuum interrupter manufacturers.

Tare da misali a nan na tester mai tsari mai yawa na vacuum interrupter, da ita daga 10 zuwa 60 kV DC, da Megger company ta bayar:

Bincike na Tsarin Tashin (MAC Test)

Bincike na tsarin tashin tana gane da Penning Discharge Principle, wanda ake kira wa Frans Michael Penning (1894-1953). Penning ya nuna cewa idan ake amfani da tsari mai yawa zuwa gwargwadon rukuni mai fata a cikin gas, kuma ake amfani da magnetic field zuwa gwargwadon rukuni, tsarin tashin da ya rasu daga bayanai na gas, tsari mai yawa, da kuma tsarin magnetic field.

Muhimmanci na Binciken

Misali a nan ya nuna muhimmanci na binciken tsarin tashin zuwa vacuum interrupter (VI). A cikin binciken tsakiya, VI ya ci a kan portable fixed magnetic coil, ko kuma flexible cable ya ci a kan sample daga wata babban sauyin. Idan ake faru binciken, ana amfani da DC tsari mai yawa zuwa VI, kuma ana ra'ayi baseline leakage current. Sannan, a cikin faruwar biyu, ana amfani da DC voltage pulse zuwa magnetic field coil, kuma ana ra'ayi total current a cikin wannan pulse. Ion current ya ci da total current minus leakage current. Saboda haka, tsarin magnetic field da tsari mai yawa su da suka san, wanda ba suka da shi shine tsari na gas. Idan ana sanne cewa adadin gas da current flow, za a iya kula da internal pressure da kula da measured current.

Hakan ya ba da damar cewa ake ra'ayi tsarin tashin zuwa vacuum interrupter, kuma hakan ya ba da kyau da gyarwa da inganci. A cikin taka changes in current under different conditions, za a iya samun abubuwan da ba su daidai, kuma hakan ya ba da damar cewa ake yi amfani da abubuwan da za su iya amfani.

Duk da cewa mafiya vacuum interrupters (VIs) suka da tsarin tashin, amma wannan tsarin tashin ya iya ci haɗin da VI ya kula da kula da asusun bayanai. Amma, tsarin tashin mai yawa ya iya kadan VI's lifespan. Idan ake bincike VIs a cikin circuit breakers a cikin routine maintenance ta hanyar traditional methods, suna ci aiki da kula da damar cewa suka yi a wannan lokaci, kuma ba suka ba da damar cewa suka yi a lokutan.

Farkon Binciken Tsarin Tashin

A yi binciken tsarin tashin ba shi da damar cewa ake yi many of the field tests da maintenance personnel suka san, kuma results su ne da damar cewa ake ra'ayi tsari na internal pressure. A cikin continued adoption of leak rate testing, electrical industry zai iya samun farko mai yawa a cikin efficiency da kula da reduction in the number of unexpected failures of VIs.

A yi binciken tsarin tashin, ake ba da damar cewa ake ra'ayi tsarin tashin zuwa abubuwan da za su iya amfani, kuma hakan ya ba da damar cewa ake yi amfani da abubuwan da za su iya amfani. Hakan ya taimaka wajen kadan tsarin tashin zuwa abubuwan, kuma ya taimaka wajen yi amfani da abubuwan da za su iya amfani, kuma hakan ya ba da damar cewa ake yi amfani da abubuwan da za su iya amfani.

Wannan bayanin ya ci a cikin refined to clearly and accurately convey the information while enhancing readability. It highlights the importance of leak rate testing and its advantages over traditional testing methods, pointing out the potential positive impacts on the electrical industry.

Using the Rigid Magnetic Coil in MAC Test on the Entire Pole

Misali a nan ya nuna cewa ake amfani da rigid magnetic coil a cikin MAC test zuwa entire pole idan a ba sai vacuum interrupter (VI) da ake amfani. A cikin many of the medium-voltage vacuum circuit breakers a cikin field, ake amfani da coil zuwa individual VIs ko individual poles, amma some do not have sufficient space or configuration to accommodate this.
