Electrical Substation Equipments

हम इस ELECTRICAL BLOG मे SUBSTATION EQUIPMENT कोणसे होते है और उनका उपयोग कैसे किया जात है ये देखने की कोशिश करेंगे इलेक्ट्रिकल EQUIPMENT’S ये उनके VOLTAGE LEVEL की हिसाब से जैसे 11KV ,22KV ,33KV 110KV ,220KV ,400 KV ,764 KV ये बिठाये जाते है , SUBSTATION ये PRIVATE CONSUMER के लिए भी INSTALL किया जाता है . जादातर SUBSTATION ये ELECTRICAL TRANSMISSION मे जहापर POWER तयार होती है और जहाँपर ये इस्तीमल होनी होती है वाहापर दोन्हो हि जगहपर बनाये जाते है . जब VOLTAGE को STEP UP (WHERE THE POWER IS STEPUP BY LOWER VOLTAGE TO HIGHER VOLTAGE) या STEPDOWN (WHERE THE POWER IS STEPDOWN BY HIGHER VOLTAGE TO LOWER VOLTAGE) करणा होता है वाहापर SUBSTATION का ERECTION किया जाता है . ELECTRICAL SUBSTATION मे POWER का METERING भी किया जाता है जो बहुत ही महत्वपूर्ण होता है . POWER BALANCING करणे के लिये भी SUBSTATION का उपयोग किया जाता है ।

TYPES OF SUBSTATION

AC SUBSTATIONS कई तरह के होते हैं. उन्हें विभिन्न मानदंडों के आधार पर विभिन्न प्रकारों में वर्गीकृत किया जाता है SOME OF THEM ARE DISCUSSED BELOW.

BASED ON THE CONSTRUCTION AND INSTALLATION OF SWITCHGEAR, ELECTRIC SUBSTATIONS ARE OF TWO TYPES.

AIR-INSULATED SWITCHGEAR SUBSTATION (OPEN TERMINAL SUBSTATION)

GAS-INSULATED SWITCHGEAR SUBSTATION (GIS SUBSTATION)

BASED ON TRANSMISSION VOLTAGE AND FUNCTION, THE ELECTRIC SUBSTATION IS CLASSIFIED INTO TWO TYPES.

TRANSMISSION SUBSTATION

DISTRIBUTION SUBSTATION

SUBSTATIONS ARE CLASSIFIED INTO VARIOUS TYPES DEPENDING UPON THEIR APPLICATIONS, NAMELY INDOOR SUBSTATION, OUTDOOR SUBSTATION, GENERATION SUBSTATION, CONVERTER SUBSTATION, DISTRIBUTION SUBSTATION, SWITCHING SUBSTATION, TRANSMISSION SUBSTATION,

A SUBSTATION IS A COMBINATION OF VARIOUS ELECTRICAL EQUIPMENT, WITH THE MOST IMPORTANT ONES BEING TRANSFORMERS, CONDUCTORS, INSULATORS, ISOLATORS, CIRCUIT BREAKERS, RELAYS, LIGHTNING ARRESTERS, BUS BARS, AND CAPACITOR BANKS.) अब हम ELECTRICAL SUBSTATION EQUIPMENT के बारे मैं देखते है , SUBSTATION मे USE किये जाने वाले EQUIPMENT’S को ELECTRICAL MAJOR EQUIPMENT’S भी कहते है . जाणते है EQUIPMENT’S के FUNCTIONS के बारे मे

TRANSFORMERS

TRANSFORMERS हैं जिनका उपयोग VOLTGE को बदले के लिए किया जाता है। इन ट्रांसफॉर्मर का उपयोग TRANSMISSION और GENRATION लिए सिस्टम के VOLTAGES स्तर को UP या DOWN करने के लिए किया जाता है। उनके डिजाइन, उद्देश्य, उपयोग और स्थापना के आधार पर TRANSFORER TYPE से FINAL किया जाता है । TRANSFORMER ये OLTC,BUCOZ RELAY,RADITORS,WINDING ,OIL,TANK इन सबी से बना होता है. ट्रांसफार्मर ये 220/110kv, 220/33kv ,110/33Kv ,33/11 kv इस तरह की रेटिंग में SUB STATION में बिठाए जाते हैं, हमेशा TRANSFORMER का जो रेटिंग होता है वह बहुत ही महत्वपूर्ण होता है.

उदाहरणार्थ, 250 KVA कॅपॅसिटी चा DG set आहे व त्याचा पवार फॅक्टर 0.8 आहे. तर खालील formula वरून आपण KW rating कसं calculate करावं ते पाहू,

ELECTRICAL CONDUCTORS

अब आगे बढते है, CONDUCTORS धातुओं से बने होते हैं जो विद्युत ENERGY को एक जगह से दुसरे जगह ट्रान्सफर करणे मे इस्तेमाल केले है । THIS HELPS IN POWER TRANSMISSION OR ELECTRIC ENERGY TRANSFER FROM GENERATING STATION TO CONSUMER POINT, WHERE POWER IS CONSUMED BY THE LOADS. THE MOST COMMONLY USED CONDUCTORS USED IN POWER SYSTEMS ARE THOSE MADE OF ALUMINUM.

Wolf – AREA (mm2)150 Current Carrying Capacity 470

Panther – AREA (mm2) 200 Current Carrying Capacity 560

Zebra – AREA (mm2) 420 Current Carrying Capacity 860

Moose – AREA (mm2) 520 Current Carrying Capacity 980

ये कुछ CONDUCTORS के TYPES है जो SUB STATION मैं COMMEONLY USE किये जाते है .

INSULATORS

INSULATORS, UNLIKE CONDUCTORS, DO NOT ALLOW FREE MOVEMENT OF ELECTRONS OR ELECTRIC CHARGE THROUGH THEM. यही कारण है कि इंसुलेटर अपने HIGH RESISTANCE के साथ बिजली का विरोध करते हैं, और शॉर्ट सर्किट से बचने के लिए कंडक्टर के साथ बिजली के खंभों को खड़ा करते समय इन्सुलेशन के लिए उपयोग किया जाता है. VARIOUS TYPES OF INSULATORS INCLUDE SUSPENSION, DISK INSULATOR, POST INSULATOR, BUS POST INSULATOR, STAY INSULATOR, PIN INSULATOR, STRAIN INSULATOR, DISK INSULATOR, AND SHACKLE INSULATORS.

INSULATORS ये दो TYPES के होते है

1) POLYMER
2) PORCELAIN

SUBSTATION और TRNASMISSION LINE मै HIGH QUALITY INSULATORS USE करणे होते है जिस से POWER TRNASMISSION ये WITHOUT TRIPING CONTINOUSLY चालता है .

DISCONNECTOR ISOLATOR IN SUBSTATION

ISOLATORS ARE MANUALLY OPERATED MECHANICAL SWITCHES THAT ISOLATE THE FAULTY SECTIONS OR THOSE SECTIONS OF CONDUCTORS OR CIRCUITS THAT NEED TO BE REPAIRED, TO AVOID THE OCCURRENCE OF HARSHER FAULTS. THE VARIOUS TYPES OF ISOLATORS USED IN DIFFERENT APPLICATIONS INCLUDE SINGLE-BREAK, DOUBLE-BREAK, LINE, AND BUS ISOLATORS.)

DISCONNECTORS (ISOLATORS) ये EQUIPMENT ये OFF-LOAD होते है जो ISOLATION करते है ,जिसका उपयोग ये MAINTENANCE के समय पर ISOLATE करणे के लिये करते है FAULTY EQUIPMENT FROM OTHER LIVE EQUIPMENT.

AT HIGHER VOLTAGES, ROTATING CENTER POST, DOUBLE END ROTATING POST, VERTICAL BREAK, AND PANTOGRAPH TYPE DISCONNECTORS ARE MORE COMMON. AIR BREAK SWITCHES ARE USED IN LOWER VOLTAGE TO DISCONNECT ON LOAD. DISCONNECTORS ये USUALLY INTERLOCKED होते है WITH THE ASSOCIATED CIRCUIT BREAKER TO PREVENT ANY ATTEMPT BEING MADE TO INTERRUPT LOAD CURRENT. DISCONNECTORS ARE NOT DESIGNED TO BREAK FAULT CURRENT ALTHOUGH SOME DESIGNS WILL MAKE FAULT CURRENT.

अधिकांश DISCONNECTORS ये A MANUAL DRIVE MECHANISM OR MOTOR-OPERATED DRIVE MECHANISM AND THE APPROPRIATE DRIVE METHOD MUST BE SELECTED FOR A PARTICULAR DISCONNECTOR IN A PARTICULAR SUBSTATION. FOR EXAMPLE, IN A REMOTELY CONTROLLED मानवरहित DOUBLE BUSBAR SUBSTATION THE BUSBAR SELECTOR DISCONNECTORS WOULD BE MOTOR OPERATED TO ALLOW ‘ON LOAD’ BUSBAR CHANGES WITHOUT A SITE VISIT BEING REQUIRED. DISCONNECTOR MECHANISMS INCORPORATE A SET OF AUXILIARY SWITCHES FOR REMOTE INDICATION OF DISCONNECTOR POSITION, ELECTRICAL INTERLOCKING, AND CURRENT TRANSFORMER SWITCHING FOR BUSBAR PROTECTION.)
