Tarihin Amfani na Isali da Kafa Zabi na Isali da Kula Tushen Yadda Ake Sake Amfani Da IEE-Business

A cikin lokacin da ake koyar da zama, yawancin da suka yi aiki suna da shafi daga cikin tushen da ake koyar da zama. A nan isolating switches da take da interlock na farko zuwa biyu, duk fassu uku suna da kyau a yi wasu wanda yana iya taka da tsari mai yawa da 3 mm, idan an rarrabe ko ake koyar da zama.

1. Abubuwa masu Muhaumin Da Dake Koyar Da Isolating Switch

A nan aiki da aki, yawancin da suka yi aiki ya kamata yanka pin da ke interlock, sannan ya fara da aiki. A baya na aiki ya kamata aiki a matsayin hanyar, amma a lokacin da contact da take da aiki ya gama da contact da ba a cika, ya kamata aiki ya kai don in saukar da aiki. Idan an samu arc a baya na aiki, ya kamata isolating switch ya koyar da zama - ba a bayyana aiki ya duba, domin haka za a haɗa arc da za su faɗi abincin. A baya na aiki, ya kamata a tabbatar da ba a yi karfi da kadan, don in ba a yi over-insertion da kuma laƙe da insulator da ke porcelaine. Ba aiki, yawancin da suka yi aiki suna da shafi da shiga cewa contacts suna da shiga - ta haka a cikin contact da take da aiki ya koyar da zama, don in ba a yi poor contact da kuma karfin da ke saukar.

(1) A nan isolating switches da take da rotation (misali, wadanda suke muka a kan shaft), ba aiki, blade ya kamata ya zama na vertical a kan plane da ke fixed contact don in ba da pressure da shiga da resistance da shiga.

(2) A nan wadanda suke muka a kan horizontal misali GW5, blade ya kamata ya zama na horizontal ba aiki, da arm da ke mutum ya ci. Idan cap da ke fixed contact ya ci a kan yau, ya nuna cewa arm da ke mutum ya ci a kan yau.

A lokacin da aiki a kan musamman, idan akwai ice ko frost a kan contacts, za a iya cire da ita a kan lokacin da ake koyar da zama da kuma a koyar da zama, don in ba da friction, don in ba da shiga da shiga ba aiki. Aiki da shiga da isolating switch ya kamata a yi da adjustment daidai na transmission mechanism - idan an samun - ko a yi da insulated operating rod idan aiki da aki.

Duk isolating switches, babu rating, ba su zama da suka koyar da zama automatic a cikin lokacin da short-circuit. Saboda haka, ba aiki, ya kamata suka tabbatar da "Five-Prevention" interlock device. Yawancin da suka yi aiki suna da shafi da shiga cewa wannan device ya koyar da zama, ya fi sanya pin da ke locking, da kuma ya koyar da interlock, don in ba a yi accidental opening da kuma accidents.

A nan tafinan: A nan aiki da aki, ya kamata aiki da shiga da karfi - amma ba a baya na aiki, ya kamata a tabbatar da ba a yi karfi, don in ba a laƙe da insulators da ke support. Idan an samu arc ko isolating switch ya koyar da zama, ba a bayyana aiki, saboda haka za a haɗa load-breaking - wani aiki mai wahala wanda za a haɗa incident.

2. Abubuwa masu Muhaumin Da Dake Koyar Da Isolating Switch

A nan aiki, ya kamata a fara da shiga da karfi. Idan an samu arc a lokacin da moving contact ya ci da fixed contact, ya kamata isolating switch ya koyar da zama da kuma aiki ya kaɓe. Amma a nan interrupting small load currents ko charging currents, arc suna da shiga; a nan lokutan, ya kamata aiki ya kai don in ba da arc da shiga. A baya na aiki, ya kamata aiki ya ci da karfi, don in ba a yi mechanical shock da insulator da ke support da kuma operating mechanism.

A nan tafinan, ya kamata a tabbatar da pin da ke interlock ya koyar da zama. Ba aiki, ya kamata a tabbatar da isolating switch ya koyar da zama: air insulation gap ya kamata ya ci da specifications, moving contact ya kamata ya ci da kadan, da kuma opening angle ya kamata ya ci da requirements da ke manufacturer. A nan isolating switches da ke indoor, idan open insulation distance ba su da shiga, ya kamata a fi sanya insulating barrier; bace, flashover da kuma short-circuit za a haɗa a kan energized side da grounded de-energized side.

A nan tafinan: A nan aiki da aki, ya kamata aiki da shiga da karfi. Idan an samu arc a baya na contacts, ya kamata isolating switch ya koyar da zama da kuma aiki ya kaɓe - sannan ya shirya cewa arc ya samu daga wani aiki mai wahala. Idan an samun cewa arc ya samu, aiki ya kamata a kai don in ba da arc da shiga da kuma ba a yi damage da contacts.

3. Tashin Aiki Idan Electromagnetic Interlock Ya Kasa

Ya kamata a tabbatar da tashin official unlocking procedures na anti-misoperation interlock devices. Ya kamata a shafi position da ke actual na equipment, da kuma a samun authorization daga on-duty dispatcher, idan an kaɓe interlock don aiki. Duk substation da ke modern suke samun isolating switches da earthing switches don grounding a lokacin da maintenance da lines, circuit breakers, ko isolators. Mechanical interlock ya samun a kan main isolating switch da earthing switch: idan main switch ya koyar da zama, earthing switch ba zama; idan earthing switch ya koyar da zama, main switch ba zama. Wannan interlock ya samun don in ba a yi accidental grounding.

4. Tashin Aiki Idan Electric Operation Ya Kasa

Idan isolating switch da ke electrically operated ya kasa, yawancin da suka yi aiki ya kamata a shirya da tabbatar da positions da ke actual na all associated circuit breakers, isolating switches, da earthing switches da suke interlock. Idan an tabbatar da cewa positions da su da shiga da safe, ya kamata operator ya kaɓe motor power supply, da kuma ya fara da aiki da aki.
