Nhanganyaya yeMidziyo:
Maelectrode eplatinum ane rectangular anotorwa. Masimba anoshandiswa nemaelectrode maviri ari pamuenzaniso ndeaya 1.0N uye 0.05N zvichiteerana. Voltage inogona kugadziriswa mukati me100~600V (48~60Hz), uye short-circuit current inogadziriswa mukati me1.0A kusvika 0.1A. Kana short-circuit leakage current yakaenzana kana kupfuura 0.5A mu test circuit, nguva inofanira kuchengetwa kwemasekonzi maviri, uye relay ichashanda kudimbura current, zvichiratidza kuti sampuli haina kukodzera. Nguva isingachinji ye drip device inogona kugadziriswa, uye drip volume inogona kudzorwa nemazvo mukati me44 kusvika 50 drops/cm3 uye drip time interval inogona kugadziriswa mukati me30±5 seconds.
Kusangana nechiyero:
GB/T4207、GB/T 6553-2014、GB4706.1 ASTM D 3638-92、IEC60112、UL746A
Nheyo yekuedza:
Kuyedzwa kwekubuda kwemvura inodonha kunoitwa pamusoro pezvinhu zvakasimba zvinodzivirira kupisa. Pakati pemaelectrode maviri eplatinum ane saizi yakatarwa (2mm × 5mm), pane voltage yakati inoiswa uye mvura inoyerera ine huwandu hwakatarwa (0.1% NH4Cl) inodonhedzwa pahurefu hwakatarwa (35mm) panguva yakatarwa (30s) kuti iongorore mashandiro ekudzivirira kubuda kwemvura pamusoro pezvinhu zvinodzivirira kupisa pasi pekushanda kwakabatana kwesimba remagetsi uye nzvimbo ine hunyoro kana yakasviba. Chiratidzo chekubuda kwemvura inodonha inoenzaniswa (CT1) uye chiratidzo chekubuda kwemvura inodonha inodonha (PT1) zvinoonekwa.
Zviratidzo zvikuru zvehunyanzvi:
1. Kamurivhoriyamu: ≥ 0.5 cubic metres, ine gonhi rekutarisa regirazi.
2. Kamurizvinhu: Yakagadzirwa nesimbi isina ngura ine ukobvu hwe1.2MM ine 304 steel plate.
3. Mutoro wemagetsi: Voltage yekuyedza inogona kugadziriswa mukati me100 ~ 600V, kana short-circuit current iri 1A ± 0.1A, kudonha kwevoltage hakufanirwe kudarika 10% mukati memasekonzi maviri. Kana short-circuit leakage current mu test circuit yakaenzana kana kupfuura 0.5A, relay inoshanda uye inocheka current, zvichiratidza kuti test sample haina kukodzera.
4. Simba pamuenzaniso nemaerekitironi maviri: Uchishandisa maerekitironi eplatinum ane rectangular, simba pamuenzaniso nemaerekitironi maviri i1.0N ± 0.05N zvakateerana.
5. Mudziyo wemvura inodonhedza: Kureba kwemvura inodonhedza kunogona kugadziriswa kubva pa30mm kusvika pa40mm, saizi yemvura inodonhedza i44 ~ 50 madonhwe / cm3, nguva iri pakati pemvura inodonhedza i30 ± 1 seconds.
6. Zvinhu zvakagadzirwa nechinhu ichi: Zvikamu zvebhokisi rekuyedza iri zvakagadzirwa nesimbi isina ngura kana mhangura, ine misoro ye electrode yemhangura, inodzivirira kupisa kwakanyanya uye ngura. Kuverengwa kwemvura inodonha kwakarurama, uye system yekudzora yakagadzikana uye yakavimbika.
7. Simba remagetsi: AC 220V, 50Hz
