1. Sinov kuchlanishi
O'zgaruvchan tok kuchlanishi o'lchanadigan suyuqlikka bog'liq, elektr maydon kuchi 0.03 kV/mm va 1 kV/mm gacha, chastotasi 40 dan 62 Hz gacha bo'lgan sinusoidal kuchlanish ishlatiladi.
2. O‘lchash
After the oil cup is filled with the oil sample, when the difference between the temperature of the inner electrode and the required test temperature is not greater than ±1 degree , the measurement of the loss factor starts, and the voltage is only applied during the measurement. After completing the first measurement, pour out the oil sample and refill the oil cup with a second sample of the same oil. The procedure is the same as the first time, but the rinsing is omitted. Repeat the measurement after warming, and the difference between the two readings should not be greater than 0.010 percent plus 25 percent of the larger value of the two measurements.
Agar bu talab bajarilmasa, xuddi shu moy namunasini yana o'zgartiring va ikkita qo'shni ko'rsatkichlar orasidagi farq ikki o'lchovning kattaroq qiymatining 0.010 foiz va 25 foizi yig'indisidan oshmaguncha sinovni bajaring. . Bu vaqtda o'lchangan natijalar haqiqiy hisoblanadi. .
Nihoyat, suyuqlik namunasi uchun yo'qotish omili sifatida ikkita haqiqiy o'lchovning pastki qismini oling.
Umumiy nosozliklar va echimlar
1. Mashina yoqilganda, quvvat kalitining ko'rsatkich chirog'i yonmaydi. Iltimos, yonib ketgan yoki yo'qligini bilish uchun elektr platasining sug'urta yadrosini tekshiring.
2. When the device is boosting the voltage, the LCD displays "electrode cup short circuit", please check whether the electrode cup is properly assembled.
3. When the device detects that the capacitance value of the empty cup deviates greatly from the standard value (60pF±5pF), please check whether the radio frequency head on the protective electrode cover of the power signal cable is loose.
4. Qurilma qizib ketganda, harorat signalini aniqlab bo'lmaydi. Iltimos, harorat signali kabeli to'g'ri ulanganligini tekshiring.
5. Uskunalar qizib ketmasa (ya'ni, oraliq chastotali isitishning maxsus ovozi yo'q), iltimos, isitish sug'urtasi puflanganligini tekshiring.
