Portativ 20kV izolyatsiya qarshiligini tekshirgich 20 kV

Mahsulot tavsifi

With the rapid development of China's power industry, electrical preventive experiments are an important part of ensuring the safe operation and maintenance of power systems. Insulation diagnosis is an important means to detect insulation or failure of electrical equipment.    At present, electrical equipment (such as transformers, generators, etc.) is developing toward a trend of increasing capacity, increasing voltage, diversifying structures, and sealing. This requires the insulation resistance tester to have large capacity, strong anti-interference ability, and easy to carry. To this end, our company specially designed and developed the instrument for the testing of electrical insulation resistance characteristics of large high-voltage transformers, electrical appliances, remote power cables or buried cables under high-voltage substations, power plants and other strong interference sites.

Ushbu asbob analog sxema, raqamli sxema va mexanik ishlashning afzalliklarini o'zida mujassam etgan va chiqish kuchlanishi, chiqish oqimi, o'lchov diapazoni, o'lchov aniqligi va shovqinlarga qarshi{0}}mahalliy yetakchi mavqeiga erishgan.

Texnik ko'rsatkichlar

1, sinov kuchlanish darajasi:

2,Test voltage accuracy:±(5 percent ＋10V)

3, qisqa tutashuv oqimi: odatiy qiymat 10mA

4, diapazon va aniqlik

Eslatma:

1)The 1MΩ range calibration voltage is 0.5kV, and the GΩ range calibration voltage is 2.5kV.

2) Qarshilikni o'lchashning aniqligini ta'minlash uchun sinov kuchlanish diapazoni: kuchlanish diapazoni nominal qiymatining 20 foizi yoki undan ko'p.

3) When the test voltage is higher than 8kV, in order to accurately measure the resistance higher than 20GΩ, the high-voltage electrode conductor exposed to the air should be shielded to avoid the influence of air ionization.

4)The 2000GΩ range is the reference range and is used in dry environments where the relative humidity is less than 70 percent .

5.Elektr maydoni aralashuviga qarshilik: 2mA (50/60Hz).

6.Timekeping, signal funktsiyasi: sekundomerning maksimal qiymati 19 daqiqa va 59 soniya, tsikli 20 daqiqa, ovozli hisobot nuqtasi 15 soniya, 60 soniya, har daqiqada, nuqta hisobotiga qisqa ovoz, qarshilik o'qish 3 soniya, o'lchangan qarshilik diapazonning pastki chegarasidan pastroqda, o'qish noto'g'ri bo'lsa, tovush doimiy ravishda eshitiladi.

7. Displey jadvali: mos ravishda sinov kuchlanishi, qarshilik va vaqtni ko'rsatadigan uchta uch-va-a-yarim LCD raqamli hisoblagich boshlari.

8.Quvvat manbai: 1,2V/2000mAh nikel-metall gidridli qayta zaryadlanuvchi akkumulyator bilan 10 qismli, jami DC12V quvvat manbai. Batareyani zaryad qilish yoki suzish uchun AC (50/60Hz) 220V kirish porti bilan.

9.atrof-muhitdan foydalanish
