Me kowane da ake amfani da su don kawo gaba da kudin ruwa a cikin sashe-babban?

1. Amfani da Masu Ma'adani na Transformers
Yana bukata a zabi transformers da kungiyoyi masu iya dogara kamar yadda ake amfani da su a cikin gwamnatin mulki, kuma a yi tasiri ga adadin karkashin mafi yawa don haka za a yi amfani da su a cikin halayen da suka fi dacewa. Yana bukata a kula tsarin karkashin transformers waɗanda suke biyo, domin a taimaka wajen gina al'amuran da suka fi dace. Transformers masu karfi a yi amfani da su - misali, transformers da suke samun alloy mai amfani da su ba suka da lalacewar shi kafin bayan lokacin da su ba suke amfani da su ba ita ce 25%–30% ta transformers S9-series, saboda haka suna da muhimmanci a amfani da su a cikin abubuwan da suke amfani da su ne kadan baya.

2. Tattalin Da Amfani Da Koyarwa Na Reactive Power Compensation
A lokacin da transformers ke amfani da su, suke amfani da reactive power wanda yake da kowane active power consumption. Amfani da reactive energy a cikin grid ya haɗa da active power losses. A cikin network da suke amfani da su a lokacin da aka yi amfani da su, ana fito reactive compensation devices a nanin low-voltage (system 400 V) transformers. Ana sani cewa amfani da load power factor zuwa 0.9–0.95 ya kai, amma reactive power compensation wanda ke faruwa a transformers - ma'anii, compensation a 10 kV high-voltage side - yana da nasararsa a yi amfani da su.

Amfani da koyarwa na reactive power compensation, wurare, da koyarwarsa, zai iya taimaka wajen gina amfani da voltage levels na system da kuma a taimaka wajen ba a ba da reactive power da take basu a fadada masu yawan lokaci, saboda haka za a yi amfani da active network losses. A cikin distribution networks, reactive compensation ana amfani da su a nanin centralized, decentralized, da local approaches. Automatic switching methods zai iya haɗa da bus voltage levels, direction of reactive power flow, power factor magnitude, load current size, ko time-of-day scheduling. Zai iya sanar da wannan a nanin load characteristics, kuma a yi takarda a nanin abubuwan da suke so:

(1) A cikin buildings masu yawan lokaci ko residential clusters inda single-phase loads ke da muhimmanci, yana bukata a duba layered single-phase reactive compensation ko automatic phase-by-phase reactive compensation. Ina amfani da sampling daga kowane phase kawai don reactive compensation zai iya haɗa da over-compensation ko under-compensation a wasu phases, saboda haka za a yi amfani da distribution network losses da kuma a yi amfani da kyau.

(2) Bayan a yi amfani da shunt capacitors, harmonic impedance na system zai canzawa, wanda zai iya haɗa da harmonics a kowane frequency. Wannan zai haɗa da capacitor lifespan da kuma zai iya haɗa da harmonic interference a cikin system. Saboda haka, a wurare da harmonic distortion mai yawa da kuma reactive compensation, yana bukata a yi amfani da harmonic filter installations.

3. Tsara Low-Voltage Distribution Lines Da Kuma Tsara Conductor Ampacity
Daga karni da suke samun conductor sizing, ana iya sanar da minimum conductor cross-section da take da muhimmanci. Amma, a nanin tsari, a yi amfani da minimum-size conductor ba zai iya haɗa da kyau. A yi amfani da conductor size kadan ko biyu a kan standard steps zai iya haɗa da savings daga reduced line losses don haka za a yi amfani da additional investment a lokacin da yake da kyau.

4. Gudanar da Number of Connection Points Da Kuma Tsara Contact Resistance
Connections bayan conductors suna da muhimmanci a cikin distribution systems, kuma yawan connection points yana haɗa da safety vulnerabilities da kuma zai iya haɗa da increased line losses. Practices a joints yana bukata a yi amfani da su da kalmomi, kuma contact resistance zai iya haɗa da conductive joint compounds. Special attention zai iya haɗa da connections bayan dissimilar materials.

5. Amfani Da Energy-Efficient Lighting Equipment
Statistics sun nuna cewa a cikin industrially developed countries, lighting yana da muhimmanci a kan 10% da total electricity consumption. A lokacin da living conditions a China ke da ci gaba, da kuma lighting requirements a public spaces ke da ci gaba, proportion of lighting electricity consumption ke da ci gaba. Arranging light sources da kalmomi a nanin building layout da lighting needs, selecting appropriate lighting methods, da kuma choosing efficient lamp types suna da muhimmanci a nanin reducing losses da kuma saving energy. Misali, 20 W energy-saving lamp wata ce take da same luminous flux da 100 W incandescent lamp. Promoting high-efficiency electric light sources, replacing magnetic ballasts with electronic ballasts, da kuma using electronic dimmers, time-delay switches, photoelectric switches, acoustic switches, da motion-sensor switches instead of toggle switches a public areas zai iya haɗa da lighting energy consumption da kuma line losses.

6. Load Shifting Da Balanced Electricity Usage
Adjust the operating modes of electrical equipment, allocate loads rationally, reduce peak-hour grid demand, and increase off-peak usage. Upgrade inefficient local distribution networks to maintain three-phase balance, ensuring balanced electricity consumption in industrial and mining enterprises and thereby reducing line losses.
