Binciken KWS-DC200-10A 0-200V DC Makamashi, Ƙarfi, Ƙarfin Wutar Lantarki Calibration

Wannan jagorar tana ba da cikakken bita da rarrabuwar KWS-DC200-10A, na'urar auna wutar lantarki ta DC mai ayyuka da yawa. Wannan na'urar kayan aiki ne mai amfani ga kowane teburin aikin lantarki, yana ba ka damar lura da wutar lantarki, halin yanzu, ƙarfi, amfani da makamashi, da zafin jiki a cikin na'ura guda ɗaya da aka saka a panel. Bayan auna kawai, yana da matuƙar amfani ga ayyuka masu amfani da yawa.

Ga wasu hanyoyin da za ka iya amfani da wannan na'urar:

• Lura da Bankunan Batura: Don tsarin hasken rana na waje ko tsarin wutar lantarki na ajiya, wannan na'urar na iya bin diddigin matakin caji da lafiyar bankin batura na 12V ko 24V a lokaci guda.
• Gina Na'urar Rubuta Amfani da Wutar Lantarki: Yi amfani da ita don auna yawan wutar da wata na'ura ko kewayawa ke amfani da ita a tsawon lokaci (a watt-hours) don fahimtar ingancinta.
• Ƙirƙirar Nuni na Wutar Lantarki na Bench: Haɗa shi cikin wutar lantarki mai canzawa na DIY don samar da bayyanannen karatu na wutar fitarwa da halin yanzu.
• Haɓaka Na'urar Gwajin Ƙarfin Batura: Ta hanyar haɗa shi da nauyin halin yanzu na dindindin, za ka iya amfani da fasalin ƙidayar amp-hour (Ah) na na'urar don auna ainihin ƙarfin batura kamar 18650 cells ko batura na lead-acid.
• Lura da Zazzabi: Thermistor ɗin da aka haɗa yana ba ka damar lura da zazzabi na heatsinks, batura, ko kwantena, yana sa ya dace da aikin babban ƙarfi wanda ke buƙatar sarrafa zafi.

Bayanin Kayan Aiki

KWS-DC200-10A ƙaramin na'urar auna dijital ce da ake saka a panel. Na'urar da aka bita ita ce sigar 10-ampere, wadda ke amfani da resistor na ciki don jin halin yanzu. Kunshin ya haɗa da na'urar kanta, littafin mai amfani tare da cikakkun zane-zane na wayoyi, da thermistor don karatun zazzabi. Na'urar tana aiki da wutar lantarki ta daban na 8-120V DC, yayin da take iya auna wutar tsarin na 0-200V DC. Wannan rabuwa yana ba da sassauci, musamman lokacin auna ƙananan wutar lantarki.

A gaba, hasken LED mai haske yana nuna duk mahimman ma'auni: Wutar Lantarki (V), Halin Yanzu (A), Ƙarfi (W), Makamashi (Wh), Ƙarfin (Ah), da Zazzabi (°C). Maɓallin dannawa guda ɗaya a gaba yana jujjuya tsakanin yanayin nuni daban-daban. A baya, za ka sami manyan tashoshi na wutar lantarki/auna, mai haɗa don thermistor, da ƙananan potentiometers guda biyu don daidaita karatun wutar lantarki da halin yanzu. Akwai kuma maɓallin sake saiti, kodayake an gano aikin sa bai dace ba a wannan na'urar da aka bita.

Jagorar Wayoyi

Wayoyi na wannan na'urar suna da sauƙi amma suna da wasu mahimman tsare-tsare dangane da saitinka. Na'urar tana da wayoyi uku na farko: ja da baƙar waya don samar da wutar lantarki na na'urar kanta (8-120V DC), da rawaya waya don auna wutar tsarin.

Tsari na 1: Auna Batura Mai Ƙarfin Wuta (8V-120V) Ba Tare da Wutar Waje Ba

Idan wutar batir ko tsarin da kake auna yana tsakanin 8V da 120V, za ka iya kunna na'urar kai tsaye daga tushen. A wannan yanayin, ja waya na na'urar an haɗa shi da madaidaicin tasha na batir, kuma baƙar waya zuwa mara kyau. Rawayan wayar jin wutar lantarki kuma an haɗa shi da madaidaicin tasha. An haɗa nauyin a jere tare da hanyar halin yanzu na na'urar.

Tsari na 2: Auna Batura Mai Ƙarancin Wuta (0V-8V) Tare da Wutar Waje

Lokacin auna tsarin ƙasa da 8V, na'urar tana buƙatar nata wutar lantarki ta waje (8-120V DC) don aiki. A wannan saitin, an haɗa ja da baƙar wayoyi zuwa wutar lantarki ta waje. An haɗa rawayan wayar jin wutar lantarki zuwa madaidaicin tasha na batir da kake auna. Hanyar halin yanzu iri ɗaya ce: madaidaicin batir yana tafiya zuwa shigar halin yanzu na na'urar, kuma an haɗa nauyin zuwa fitar halin yanzu.

Tsari na 3: Amfani da Shunt na Waje (don sigogin 50A, 100A, da sauransu)

Manyan sigogin wannan na'urar (50A, 100A) suna amfani da resistor shunt na waje. A wannan yanayin, an sanya shunt a cikin hanyar dawowa mara kyau na kewayawa. An haɗa wayoyin jin wutar lantarki na na'urar a ƙetaren shunt don auna raguwar wutar lantarki, wanda yake daidai da halin yanzu. Wayoyi sun ɗan bambanta kuma an bayyana su a fili a cikin littafin da aka haɗa. (a cikin bidiyo a 07:07)

Yana da mahimmanci a tuna cewa samar da wutar lantarki na ciki na na'urar ba zai iya ɗaukar fiye da 120V ba. Idan kana auna tsarin sama da 120V, dole ne ka yi amfani da wutar lantarki ta waje don kunna na'urar kanta. (a cikin bidiyo a 09:32)

Gwaji da Daidaitawa

Binciken ya ƙunshi gwada mitar da samar da wutar lantarki mai canzawa da kuma nauyin lantarki. An gano karatun wutar lantarki yana da inganci sosai, yana dacewa da wutar shigar kusan daidai. Karatun na yanzu kuma yana da inganci sosai, tare da ɗan ƙaramin bambanci na 20-30 milliamps a manyan igiyoyin ruwa (misali, yana nuna 8.08A lokacin da aka zana 8.00A), wanda kuskure ne maras muhimmanci. (a cikin bidiyo a 11:44)

Idan ka ga karatun ba daidai ba, za ka iya daidaita mitar ta amfani da ƙananan potentiometers guda biyu a baya. Wanda ya fi kusa da resistor na shunt yana daidaita karatun na yanzu, kuma ɗayan yana daidaita wutar lantarki. Ta hanyar juya waɗannan ƙananan screws a hankali, za ka iya daidaita nunin don dacewa da sanannen tunani. (a cikin bidiyo a 19:54)

Rushewa da Abubuwan Ciki

Buɗe mitar yana bayyana PCB mai inganci, wanda aka gina shi da fasaha. Babban abubuwan sune microcontroller na Nuvoton MS51FB9AE, wanda ke aiki a matsayin kwakwalwar na'urar, da kuma op-amp na H6203 don daidaita siginar. Resistor na shunt na ciki babban abu ne na 0.05-ohm (5 milliohm) wanda aka tsara don ɗaukar cikakken 10A na yanzu. (a cikin bidiyo a 16:36)

Na'urar da aka yi bita tana da ƙaramin matsala inda maɓallin sake saiti a baya bai yi aiki kamar yadda ake tsammani ba, duk da cewa wani sharhi a gidan yanar gizo ya nuna ya kamata ya yi aiki.

A cikin nunin kai tsaye, an haɗa mitar zuwa samar da wutar lantarki na 12V da kuma nauyin lantarki da aka saita don zana 5A. Mitar ta nuna daidai 12.2V da 5A, yana tabbatar da aikin sa na gaske. Nunin kuma ya nuna ikon mitar na bin diddigin amfani da kuzari a tsawon lokaci, yana nuna watt-hours da lokacin gudu da aka tara. Wannan ya sa ya zama kayan aiki mai amfani kuma abin dogaro ga kowane aikin da ke buƙatar ingantaccen sa ido na wutar DC. (a cikin bidiyo a 20:36)
