使用說明書Directions for use
儀器正確連接后，接通電源到額定電壓，工作指示燈亮。After the instrument is connected correctly, connect the power supply to the rated voltage, and the working indicator light is on.
將鈕子開關(guān)打到“試驗(yàn)”位置，“越限”指示燈亮，經(jīng)數(shù)秒延時(shí)后“動(dòng)作”指示燈亮，但繼電器不會(huì)動(dòng)作，說明裝置內(nèi)部邏輯功能正常。其延時(shí)時(shí)間即為為逆功率繼電器延時(shí)，其值可通過“延時(shí)時(shí)間”調(diào)節(jié)電位器進(jìn)行調(diào)整，順時(shí)針為增大方向。然后，將鈕子開關(guān)打到“運(yùn)行”位置。Press the button switch to the "test" position, and the "out-of-limit" indicator light is on. After a few seconds of delay, the "action" indicator light is on, but the relay will not move, indicating that the internal logic function of the device is normal. The delay time of the reverse power relay is the delay time of the reverse power relay. Its value can be adjusted by adjusting the potentiometer through the "delay time", and clockwise is the increasing direction. Then, set the button switch to the "run" position.
注意：二次試驗(yàn)的時(shí)間間隔應(yīng)大于30秒。否則，第二次試驗(yàn)的“延時(shí)時(shí)問”會(huì)偏短。Note: The time interval of the second test should be greater than 30 seconds. Otherwise, the "delay time question" of the second trial will be too short.
-P調(diào)逆功功率3%～15%（連續(xù)可調(diào)），S調(diào)延時(shí)時(shí)間3～10S（連續(xù)可調(diào)）。-P adjusts inverse power 3%～15% (continuously adjustable), and S adjusts delay time 3～10s (continuously adjustable).
機(jī)組并聯(lián)運(yùn)行時(shí)，電壓保持額定，讓某臺(tái)機(jī)組逆功，達(dá)一定值時(shí)逆功率“越限”指示燈亮，經(jīng)延時(shí)后“動(dòng)作”指示燈亮，繼電器動(dòng)作將主開關(guān)跳閘，逆功機(jī)組介列，動(dòng)作功率可以通過“動(dòng)作功率”調(diào)節(jié)電位器進(jìn)行調(diào)節(jié)，順時(shí)針為增大方向。Unit parallel operation, keep the rated voltage, an inverse work units, up to a certain value when the reverse power indicator "the limit", "action" after delay indicator, relay action will be the main switch trip, inverse power unit dielectric column, action power can be adjusted through the "power" to adjust potentiometer, clockwise to increase the direction.
如在逆功時(shí)繼電器不動(dòng)作，則可能有一相電流互感器的極性接反，應(yīng)將接到接線端子的3, 4（或5、6）號(hào)線對(duì)調(diào)，對(duì)調(diào)后如在正功率時(shí)繼電器動(dòng)作，應(yīng)再將電壓接線端子的1.2號(hào)線對(duì)調(diào)即可。如在單機(jī)運(yùn)行，正功率時(shí)，繼電器就動(dòng)作，則應(yīng)把電壓接線端子1、2號(hào)線對(duì)調(diào)。If the relay does not operate during the reverse power, the polarity of a current transformer may be reversed, so the No. 3, 4 (or 5, 6) line connected to the terminal should be switched. After the switch, if the relay is in operation during the positive power, the No. 1.2 line of the voltage terminal should be switched. If running in a single machine, positive power, the relay will operate, the voltage terminal 1, 2 line should be switched.
額定電壓：AC100V-220V-380V-440V，50／60HZ, A、C 二相功耗＜2VA。Rated voltage: AC100V-220V-380V-440V, 50/60Hz, A, C two-phase power consumption < 2VA.
額定電流5A, A、C 二相、功耗＜1VA。Rated current 5A, A, C two phase, power consumption < 1VA。
注Note
接線時(shí)要注意電流互感器的同名端，連接要可靠鎖緊。When wiring, pay attention to the same name end of the current transformer, and the connection should be reliably locked.
如需方要求供貨方整定動(dòng)作功率和延時(shí)時(shí)間，可在訂貨時(shí)注明，如不提要求則按動(dòng)作電流400mA（額定電流的8%)cos Ψ = 0.8延時(shí)時(shí)間為5秒進(jìn)行整定出廠。If the buyer requires the supplier to set the operating power and delay time, it can be indicated at the time of ordering. If not, the operating current is 400mA (8% of the rated current) COS Ψ = 0.8, and the delay time is 5 seconds.
