It is an ideal choice for design, manufacturing and use departments.

          技術參數Technical parameters 

          在電網電壓變化為額定電壓的±10%范圍內,頻率變化為額定頻率的±5%范圍內裝置能正常工作。The devices can work normally within the range of ± 10% of the rated voltage and ± 5% of the rated frequency.

          當并聯運行機組的逆功率值達額定的3~15%(連續可調)延時3~10秒(連續可調)逆功率繼電器動作。When the reverse power value of the parallel operating unit reaches the rated 3~15% (continuously adjustable) delay time of the reverse power relay is 3~10 seconds (continuously adjustable).

          測量范圍Measuring range:current(ln):5Aac;voltage(Un):100V-380V-440Vac.

          外殼防護Housing protection:IP20。

          耐電壓 Dielectric test:AC2.6KV,50HZ,1min。

          輸出觸點容量 Contact rating:AC250V,5A;DC28V,5A。

          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.

          將鈕子開關打到“試驗”位置,“越限”指示燈亮,經數秒延時后“動作”指示燈亮,但繼電器不會動作,說明裝置內部邏輯功能正常。其延時時間即為為逆功率繼電器延時,其值可通過“延時時間”調節電位器進行調整,順時針為增大方向。然后,將鈕子開關打到“運行”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:二次試驗的時間間隔應大于30秒。否則,第二次試驗的“延時時問”會偏短。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調逆功功率3%~15%(連續可調),S調延時時間3~10S(連續可調)。-P adjusts inverse power 3%~15% (continuously adjustable), and S adjusts delay time 3~10s (continuously adjustable).

          機組并聯運行時,電壓保持額定,讓某臺機組逆功,達一定值時逆功率“越限”指示燈亮,經延時后“動作”指示燈亮,繼電器動作將主開關跳閘,逆功機組介列,動作功率可以通過“動作功率”調節電位器進行調節,順時針為增大方向。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.

          繼電器動作將主開關跳閘,逆功機組介列,動作功率可以通過“動作功率”調節電位器進行調節,順時針為增大方向。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.

          如在逆功時繼電器不動作,則可能有一相電流互感器的極性接反,應將接到接線端子的3, 4(或5、6)號線對調,對調后如在正功率時繼電器動作,應再將電壓接線端子的1.2號線對調即可。如在單機運行,正功率時,繼電器就動作,則應把電壓接線端子1、2號線對調。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-380V-440V,50/60HZ, A、C 二相功耗<2VA。Rated voltage: AC100V-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作功率和延時時間,可在訂貨時注明,如不提要求則按動作電流400mA(額定電流的8%)cos Ψ = 0.8延時時間為5秒進行整定出廠。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.
