使用說明Directions
當(dāng)待并聯(lián)發(fā)電機(jī)的電壓和頻率大于電網(wǎng)的電壓和頻率時(shí)，電壓差、頻率差指示的指針應(yīng)向“+”方向偏轉(zhuǎn)；如果小于電網(wǎng)的電壓和頻率時(shí)，電壓差、頻率差指示的指針應(yīng)向“—”方向偏轉(zhuǎn)。When the voltage and frequency of the parallel generator are greater than that of the grid, the pointer of voltage difference and frequency difference should be deflected to the direction of "+". If it is less than the voltage and frequency of the grid, the pointer of voltage difference and frequency difference indicator should be deflected to the direction of "-".
如果當(dāng)待并發(fā)電機(jī)的頻率大于電網(wǎng)頻率時(shí)，同期指示的指針應(yīng)作順時(shí)針方向旋轉(zhuǎn)；小時(shí)電網(wǎng)頻率時(shí)，應(yīng)作逆時(shí)針方向旋轉(zhuǎn)。If the frequency of the generator to be combined is greater than the frequency of the grid, the pointer indicating the same period shall rotate clockwise; When the power grid frequency is small, it should be rotated counterclockwise.
當(dāng)待并聯(lián)發(fā)電機(jī)的頻率與電網(wǎng)的頻率相差0.25～0.7HZ范圍內(nèi)時(shí)，且電壓相同，則同期指示應(yīng)能正常旋轉(zhuǎn)。When the frequency of the parallel generator is within the range of 0.25～0.7Hz from the frequency of the grid, and the voltage is the same, the corresponding indication should be able to rotate normally.
儀表的額定頻率為50HZ，偏離到48～52HZ范圍內(nèi)任一頻率時(shí)，引起儀表指示值的改變不應(yīng)超過基本誤差。When the rated frequency of the instrument is 50HZ and deviates to any frequency within the range of 48 ~ 52HZ, the change of indicating value of the instrument shall not exceed the basic error.
當(dāng)電壓額定值偏離±10%時(shí)，引起儀表指示值改變不應(yīng)超過基本誤差。When the voltage rating deviates from ±10%, the change in the indicating value of the instrument should not exceed the basic error.
