Intshayelelo yezixhobo:
Ii-electrode zeplatinum ezizinxantathu ziyasetyenziswa. Amandla asetyenziswa zii-electrode ezimbini kwisampuli yi-1.0N kunye ne-0.05N ngokwahlukeneyo. I-voltage ingalungiswa ngaphakathi koluhlu lwe-100 ~ 600V (48 ~ 60Hz), kwaye i-current-circuit current ingalungiswa ngaphakathi koluhlu lwe-1.0A ukuya kwi-0.1A. Xa i-current-circuit leakage ilingana okanye ingaphezulu kwe-0.5A kwisekethe yovavanyo, ixesha kufuneka ligcinwe imizuzwana emi-2, kwaye i-relay iya kusebenza ukusika i-current, nto leyo ebonisa ukuba isampuli ayifanelekanga. Ixesha elihlala lihleli lesixhobo se-drip lingalungiswa, kwaye i-drip volume ingalawulwa ngokuchanekileyo ngaphakathi koluhlu lwe-44 ukuya kwi-50 drops/cm3 kwaye ixesha le-drip lingalungiswa ngaphakathi koluhlu lwe-30±5 seconds.
Ukuhlangabezana nomgangatho:
GB/T4207、GB/T 6553-2014、GB4706.1 ASTM D 3638-92、IEC60112、UL746A
Umgaqo wovavanyo:
Uvavanyo lokukhupha ukuvuza lwenziwa phezu kwezinto eziqinileyo zokukhusela ubushushu. Phakathi kwee-electrode ezimbini zeplatinum ezinobukhulu obuthile (2mm × 5mm), kusetyenziswa i-voltage ethile kwaye ulwelo oluqhubayo lomthamo othile (0.1% NH4Cl) luwiswa kubude obuthile (35mm) ngexesha elimiselweyo (30s) ukuvavanya ukusebenza kokumelana nokuvuza komphezulu wezinto zokukhusela ubushushu phantsi kwesenzo esidibeneyo sentsimi yombane kunye nendawo efumileyo okanye engcolileyo. Isalathisi sokukhupha ukuvuza esithelekisekayo (CT1) kunye nesalathisi sokumelana nokuvuza (PT1) ziyamiselwa.
Izalathisi zobugcisa eziphambili:
1. Igumbiumthamo: ≥ 0.5 cubic metres, kunye nomnyango wokujonga iglasi.
2. Igumbiizinto: Zenziwe ngepleyiti yentsimbi engagqwaliyo eyi-1.2MM ubukhulu bayo obuyi-304.
3. Umthwalo wombane: I-voltage yovavanyo ingalungiswa ngaphakathi kwe-100 ~ 600V, xa i-short-circuit current iyi-1A ± 0.1A, ukuhla kwe-voltage akufanele kudlule i-10% kwimizuzwana emi-2. Xa i-short-circuit leakage current kwi-test circuit ilingana okanye ingaphezulu kwe-0.5A, i-relay isebenza kwaye inqumla i-current, nto leyo ebonisa ukuba isampuli yovavanyo ayifanelekanga.
4. Ukunyanzela isampuli ngee-electrode ezimbini: Ukusebenzisa ii-electrode zeplatinum ezizingxande, amandla kwisampuli yee-electrode ezimbini yi-1.0N ± 0.05N ngokwahlukeneyo.
5. Isixhobo solwelo oluwisayo: Ukuphakama kolwelo oluwisayo lungalungiswa ukusuka kwi-30mm ukuya kwi-40mm, ubungakanani bolwelo oluwisayo bungama-44 ~ 50 drops / cm3, ixesha eliphakathi kolwelo oluwisayo yi-30 ± 1 seconds.
6. Iimpawu zemveliso: Izinto ezakhiweyo zebhokisi yovavanyo zenziwe ngentsimbi engatyiwayo okanye ubhedu, ezineentloko ze-electrode yobhedu, ezimelana nobushushu obuphezulu kunye nokugqwala. Ukubalwa kokuwa kolwelo kuchanekile, kwaye inkqubo yolawulo izinzile kwaye ithembekile.
7. Umbane: AC 220V, 50Hz
