1.在成套装置接线正确无误、供电电源正常的情况下,将电容补偿柜的智能无功功率控制器的电源开关(微型断路器)暂时置断开位置(OFF位置),成套装置各柜体里面的其他电源开关(微型断路器)均置接通位置(ON位置)。
2.将成套装置1#进线柜里面的主电路开关(塑壳断路器)均置接通位置(ON位置)。
进线开关柜(1#柜)内的主断路器(QF1)为电动预储能合闸方式,其合闸过程请按下面的3操作。
3.首先按下“储能”按钮,主断路器储能电动机动作并带动弹簧开始储能,储能结束后(此时储能指示灯亮),按下“合闸”按钮,弹簧储能释放,使主断路器(QF1)完成合闸动作。
主断路器合闸后,合闸指示灯亮,分闸指示灯灭,储能指示灯也灭。
4.在1至3操作完成之后,且各种指示均正常的情况下,转换开关切换到手动状态(非自动状态)后,旋转转换开关,投切相应电容,对应的回路指示灯亮,接触器线圈吸合,主回路中接触器接通后其下接电容投入到电网中。
此时可检测整个系统中各个电容的回路是否正确。
5.在各种指示均正常的情况下,接通电容柜智能无功功率控制器的电源开关(置ON位置),控制器接通电之后显示”CAL”,5秒后进入自动工作状态,如输入电流符合最小要求(大于150mA),将显示所测电网功率因数cosφ。
此时可设置控制器的参数,可将控制器的“功率因数值”cosφ设置为0.95或者0.96(要比所测电网功率因数cosφ大),同时设定模式设置为人工设定模式。
将转换开关切换至自动状态,将“投切允许”打至右位即(ON位置),无功补偿成套装置将投入正常工作。
此时可以手动按下无功补偿控制器上的”增加”按钮来投切相应电容,对应的回路指示灯亮,接触器线圈吸合,主回路中接触器接通后其下接电容投入到电网中,直到补偿后的功率因数达到预定的设置为止,而相反按“减少”可切除相应电容。
当设定参数时,将控制器的“功率因数值”cosφ设置为0.95或者0.96(要比所测电网功率因数cosφ大),可将设定模式设置为全自动设定模式。
此时将“投切允许”打至右位即(ON位置),将转换开关切换至自动状态,无功补偿成套装置将投入正常工作。
此时控制器将进行“自学过程”,在数据初始化过程中,控制器按既定“功率因数值”与现配电系统作比较,并系统地启动电容器,改善功率因数,同时记录所接入电容器组的值,寻找到最小电容器组作为无功投入门限。
此时对应的回路指示灯亮,接触器线圈吸合,主回路中接触器接通后其下接电容投入到电网中,直到投入电容器组达到投入门限为止。
此时按下“增加”键可调出动态参数显示代码:I(电流),U(电压),Q(无功功率),P(有功功率),再按“减少”键可调出动态参数对应显示值,按”菜单设置”键可返回主显示值:功率因数cosφ。
6.如果要使自动无功补偿成套装置停止运行,应先将转换开关切换至手动状态(HAND),将其投入的电容全部切掉。
如果要测试控制器的保护功能,可以将电压调高于额定电压(如额定电压为380V,可加压至400V),此时控制器可自动快速(5秒)逐级切除已投入的电容器组,并显示电压值。
而将电流互感器的次级信号调至低于150mA时,控制器会封锁电容器的投入,并同时自动快速(5秒)逐级切除已投入的电容器组。
而设置控制器的参数时,可将控制器的“功率因数值”cosφ设置为0.95或者0.96(要比所测电网功率因数cosφ大),同时设定模式设置为人工设定模式。
将转换开关切换至自动状态,将“投切允许”打至右位即(ON位置),无功补偿成套装置将投入正常工作。
此时可以手动按下无功补偿控制器上的”增加”按钮来投切相应电容,对应的回路指示灯亮,接触器线圈吸合,主回路中接触器接通后其下接电容投入到电网中,直到补偿后的功率因数达到预定的设置为止,此时如果再继续投切,超过预设“功率因数值”时,控制器可自动快速(5秒)逐级切除已投入的电容器组。
7.接通风机电源,柜顶风机利用温度控制器进行自动控制。
顶部的风机由温控开关控制,当温度达到预定温度时,温控开关接通,风机开始运行;当温度低于预定温度时,温控开关断开,风机停止运行。
英文版:Step 1: When the complete device wiring is correct, the power supply situation is normal,put the power switch of intelligent capacitor compensation to the off position (OFF position) temporarily, and set the other power supply of each cabinet to the on position (ON position).Step 2: The main circuit switch inside the 1# line cabinet are arranged on position (ON position),then themain circuit breaker(QF1) inside in 1# cabinet will in the position of electric storage,the closing process please read the following 3 operations.Step 3: First,press the “storage” button,the electric motor of the main circuit breaker begin to storage the energy,then the indicating lamp of storage is bright at the end of this step.Secondly, press the “close”button,the mechanical spring release the energy,so as to put the main circuit breaker(QF1) to the closing position.Thirdly,after the main circuit breaker is closed,the closing indicator lights is bright ,the brake lights and the indicating lamp of storage is extinguished.Step 4:When the Step1 to Step3 are complete,and all instructions are under normal circumstances, if you switch rotary to manual mode(non automatic state), you can switch the capacitor. Then the indicating lamp corresponding circuit is bright, the coil of the contactor is attracted,at the same time, the contactor in main circuit is switched on, and the capacitor isinput into the grid.Now you can detect whether each circuit of capacitance in the system is correct or not. Step 5: When all instructions are under normal circumstances,put the power of intelligent wattless controller inside capacitor cabinet to the on position, the controller will display “CAL” after it is switched on,and it will get into the automatic status in 5 seconds,if the current of input can satisfies the minimum preset(such as greater than 150mA),it will display Power Factor(cosφ).Then you can set the parameters of the controller,you can set the Power Factor to 0.95 or 0.96(it must be greater than the measured power factor cosφ),and set the mode in Manual mode.Then you can switch the conversion to automatic state, and put the "switching allows" to the right location (position ON),and the wattless compensation equipment will be put to work.Now you can pressed “add” button on the wattless power compensation controller to switch the corresponding capacitor,the indicator lights corresponding circuit are bright at the same time,the contactor coil is attracted, and contactor in main circuit is switched on,and thecapacitor is put into the grid,until the Power Factor reaches the predetermined set,whereas press “sub”button can cut off the corresponding capacitor.When you set the parameters of the controller,you can set the Power Factor to 0.95 or 0.96(it must be greater than the measured power factor cosφ),and set the mode in Automatic mode.Then you can put the "switching allows" to the right location (position ON),and switch the conversion to automatic state, the wattless compensation equipment will be put to work.The controller will be set in “self-learning”process,when it initializes the data,it will compare the Power Factor which is switched the capacitor into the grid to the Power Factor which is preset in the controller,then start the capacitor systematically,so as to improve the Power Factor,and take a record about the value of capacitor at the same time,just to get the minimum number of the capacitor group as the threshold.At this time,the indicator lights corresponding circuit are bright at the same time,the contactor coil is attracted, and contactor in main circuit is switched on,and the capacitor is put intothe grid,until the number it inputs reaches to the threshold.Then you can press the “add”button to show the dynamic parameter:I(regard as current),U(regard as voltage),Q(regard as wattless power),P(regard as active power),and you can press “sub”button to show the value corresponding to the parameters,and you can also press “menu” to return to the main screen to display the value:Power Factor(cosφ).Step 6:If you want to stop the automatic wattless power compensation equipment,you should convert the switch to manual state,the whole capacitors it inputs will be cut off. If you want to test the function of protection of the controller,you can set the voltage,when it higher than the rated voltage(such as the rated voltage is 380V,and you can put the voltage to 400V),now the controller can gradually cut off the capacitor which has been invested automatically and quickly,and display the voltage at the same time.While you set the secondary signal of the current transformer below 150mA,the controller will lock the investment of the capacitor,and the controller can gradually cut off the capacitors which have been invested automaticallyand quickly.And when you set the parameters of the controller,you can set the Power Factor(cosφ)to0.95or 0.96(it must be greater than the measured power factor cosφ),and set the mode in Manual mode.Then you can switch the conversion to automatic state,and put the "switching allows" to the right location (position ON), the wattless compensation equipment will be put to work.Now you can pressed “add” button on the wattless power compensation controller to switch the corresponding capacitor,the indicator lights corresponding to circuit are bright at the same time,the contactor coil is attracted, and contactor in main circuit is switched on,and the capacitor is put into the grid,until the Power Factor reaches the predetermined set,while you just put more capacitor into grid,the Power Factor will greater than the preset parameter,the controller can gradually cut off the capacitors which have been invested automatically and quickly.Step 7:Turn on the the fan power, the temperature controller will automatic control the fan. The top of the fan is controlled by a temperature controller, whenthe temperature reaches the preset temperature, the temperature controller is turned on, the fan will run; when the temperature is lower than the preset temperature, the temperature controller is turned off, and the fan stops running.。
