稳压直流电源产品说明书

稳压直流电源产品说明书

一、 方案设计方案原理框图如图1所示。

图1 方案原理框图二、电路设计1、整流滤波电路设计整流滤波电路如图2所示。

交流220V 电压经T1降压、VD1~VD4整流及C1滤波后,为后续电路提供20V 直流工作电源。

图2 整流滤波电路2、稳压电路设计稳压电路如图3所示。

稳压电路是个具有电压串联负反馈的闭环系统。

其稳压过程为,当电网电压波动或负载变动引起输出直流电压发生变化时,取样电路取出输出电压的一部分送入比较放大器,并与基准电压进行比较,产生的误差信号经T2放大后送至调整管T1的基极,使调整管改变其管压降,以补偿输出电压的变化,从而达到稳定输出电压的目的。

L50%图3 稳压电路3、输出参数调节及负载电路输出参数调节及负载电路如图4所示。

(1)输出电压Uo 及输出电压调节范围:)U (U R R R R R U BE2Z W 22W 1O +"+++=调节Rw 可以改变输出电压Uo 。

(2)最大负载电流Iomax 。

稳压电源正常工作时能输出的最大电流。

调节Rl 可以改变Io 。

50%Q1图4 输出参数调节及负载电路三、电路测试切断工频电源,连接好被测电路。

1、初测。

稳压器输出端负载开路,断开保护电路,接通220V工频电源,调节电位器Rw,观察Uo的大小和变化情况。

观察结果显示,Uo岁Rw线性变化,说明该稳压电路各反馈环路工作基本正常。

2、测量输出电压可调节范围。

接入负载,并调节Rl,使输出电流Io≈100mA,此时接入的负载阻值为156Ω,满足驱动负载在120Ω~240Ω的范围内,如图5所示。

再调节电位器Rw。

当将电位器Rw调节到最大值时,测量输出电压达到限定范围的最小值,此时Uo为6V左右,如图6所示;当将电位器Rw调节到最小值时,测量输出电压达到限定范围的最大值,此时Uo为15V左右,如图7所示,即满足稳压电源输出直流可调电压6V<Uo<15V这一技术指标的要求。

该过程中如不满足要求,可适当调整R1、R2的值。

一、产品概述市场中的节电装置大都不具备稳压的功能,仅仅降低装置的供电电压,从而达到节电的目的。

其弊端为:当电网电压稍有波动时,装置的输出电压升高,不再节电;或者输出电压降得更低,对负载的影响较大。

由此可见,稳压功能是节电装置必备的一项功能,也是能够实现节电的必要条件。

LH-100型智能节电装置根据用户电网电压的波动情况、照明负载的性质,为负载提供稳定的供电电压。

用户可根据需求,设置输出电压,对负载的运行时间和供电方式进行编程,最大限度地降低负载的电耗。

二、结构它是由三相补偿变压器、三相调压变压器、传动机构、电刷接触系统、箱体和控制系统等组成。

三相调压变压器圆筒式绕组外表面经磨光加工,去除绝缘,呈光滑的导体面,以便于电刷良好接触;传动机构由电动机和蜗轮、蜗杆、链轮、链条组成;电刷系统结构合理可靠,以保证电刷压力;箱体采用封闭柜式,体积小,散热好,检测仪表位置醒目,提示准确。

三、工作原理LH-100系列节电装置由三相补偿变压器TB、三相调压变压器TUV电压检测单元、电动机控制与传动机构,接触操作电路等组成,其电气原理图一所示。

图一自动补偿电力稳压器电气原理图调压变压器TUV的一次绕组接成Y形,连接在稳压器的输出端,二次绕组连接补偿变压器TB的一次绕组,而补偿变压器工作原理,如图二所示。

若不计补偿变压器阻抗压降,则从图二可见:Uao=Uai+Uac式中:Uai—稳压器A相输入电压;Uao—稳压器A相输出电压;Uac—稳压器A相补偿电压;图二单相补偿电力原理图其原理是:当A相输入电压Uai增加ΔUai时,补偿电压Uac也相应改变ΔUac且ΔUac=-ΔUai时,使A相输出电压Uao保持不变,同理B相、C相也是如此。

其稳压调压过程是:根据输出电压的变化,由电压检测单元采样,检测并输出信号控制电动机SM转动,经减速机构并有链条带动调压变压器TUV上的电刷组滑动(或滚动)来调节调压器的第二次电压,以改变补偿电压的极性和大小,降低或升高输出电压,进而达到节电的目的。

四、基本部件与电路1、补偿变压器当一次线圈上所加电压的大小和极性发生变化时,能使串联在负载回路上的二次线圈产生幅值和极性可变的补偿电压变压器。

2、调压变压器调压变压器TUV是一台能自动调节二次电压的三相自耦变压器。

它具有三对能自动对称滑动的电刷。

电动机经链条带动电刷沿自耦变压器圆筒式绕组裸露部分(滑道上)滑动,平稳地调节二次电压,以达到改变补偿电压,维持输出电压稳定的目的。

3、电动机控制电路(见图四)伺服电机控制方式有“手动”、“自动”两种,由切换开关QT1选择。

在“手动”位置时:要提高输出电压按SB3“升压”按钮,要降低输出电压按SB4“降压”按钮,直到输出电压符合供电要求,此时,本机不具有稳压功能;选在“自动”时:升压和降压检测单元自动控制,实现“自动”稳压功能。

4、三相主电路开关装置及操作电路1)稳压主电路设置了一只自动开关Qa、一只接触器和一只刀开关。

(详见图4)是为使电压自动补偿系统能方便地投入和退出而设置的。

投入稳压运行时,只要把刀开关手柄置“稳压”按钮,按“稳压”按钮,交流接触器合上即可;需要电网直接直通时,只要把刀开关手柄置“市电”位置即可。

2)在接触器合闸电路中串联了过压和欠压保护继电器Kc3和相序、缺相保护继电器KC4的常开接触点,在稳压运行中,只要输出端电压、欠压或缺相、错相时即能自动跳闸保护,并报警,需按“停止”按钮,清除保护状态后才可启动。

3)500KV A以上节电装置省略交流接触器和QA开关,采用DW系列万能式自动空气开关断路器实现断路,当过压、欠压、缺相、错相时补偿系统自动退出运行。

5、三相稳压器电压检测和调节单元采样控制变压器TC从稳压器输出端取出采样电压和控制电压,控制电压经变压、整流滤波及稳压后由RP1、RP3分压得到上限基准电压。

采样电压经变压、整流、滤波得到随输出电压变化的信号电压,输出到比较器进行比较,当信号电压处于上限和下限基准电压之间时控制继电器KC1、KC2触点均处于断开位置。

当信号电压超过上限和下限基准电压即(精度)时,KC1(KC2)和接触电器KA1(KA2)动作。

电动机转动调节补偿电压、使稳压器输出电压稳定。

总之,当输出电压变化超过额定精度允许范围时,电压检测便发出调节输出电压指令,直到输出电压恢复到额定精度允许的范围。

节电装置的稳定精度由电位器RP3在±1%至5%之间调整。

额定输出电压的中心位置由调节电位器RP1来调整。

6、三相保护电路1)自动开关QA保护主电路过载及短路。

QLS1和QLS2限位开关组成越限保护电路:当电刷滑动触及上下限位开关时,其电压调节继电器的线圈失电,使继电器释放,伺服电机停转,达到越限保护作用。

2)过压和欠压保护在正常运行状态下控制继电器KC3常闭触点,处于闭合状态,当信号电压高于过压保护额定电压或低于欠压额定保护电压时(过压电压设定为420V左右,欠压电压设定为320V),保护继电器常闭点断开,并使接触器KM断开自动补偿系统退出工作状态时,同时发出声光告警。

3)相序和缺相保护电路。

当三相电源进线相序错位或缺相时,相序保护器指示灯不亮,整机处于自动保护状态。

7、本机设有A、B两块控制板,在使用过程中,若发现A板控制有故障,可拨动备用板转换开关至B板,B板即可代替A板投入使用。

8、单相稳压器电压检测和调节单元单相稳压器电压检测和调节单元的工作原理和三相稳压器电压检测和调节单元完全相同。

自动开关QA保护主电路过载及短路,电压自动补偿系统设置了越限保护。

越限保护由QLS1和QLS2限位开关组成,当电刷滑动到两端碰撞限位开关时,其常闭点断开,电动机停转。

过压保护电路在正常运行状态下,控制继电器常闭触点闭合状态,当信号电压高于过压保护额定值时,控制继电器常闭触点断开使接触器KM断开,自动补偿系统退出工作。

自动和分调稳压器电路如图三、图四、图五、图六。

八、订货须知1、订货时应说明产品型号、容量、额定输出电压、输入电压变化范围、稳定精度、电源输入位置。

2、有特殊要求,请与本厂技术部联系,你将获得完善的专业咨询。

2)测试点对地(机外壳)用1000V兆欧表测试绝缘电阻值应大于1M Ω,如小于1MΩ应检查原因,或用电热器烘干柜内潮气,直到绝缘电阻达到标准为止。

4、安装接线1)225kV A节电装置以下连接进线:输入电源A、B、C三相导线由柜后下方引进穿进电流互感器,(匝数按铭牌要求)接至柜内空气开关的桩头(标有输入接线A、B、C字样)2)320kV A以上节电装置连接进线:输入电源A、B、C三相导线接至空气开关(或空气断路器)上桩头所对的铜母排上(母排上标的输入电压及A、B、C字样)3)多柜产品柜间连接线:双柜和四柜产品的柜间连接线,可选用不小于1mm²铜软线在柜间端子接线排上按上至下对应连接即可。

4)连接输出线:节电装置上标有“输出电压”的各接线端子接负载,连接线规格由用户根据负载大小而定,一般应与进线线规相同。

5)机壳保护接地:接地线线规应按当地供电部门有关规定执行,接地线应接至机柜内标有“接地线”的桩位上,接地线电阻应小于0.4MΩ。

5、检查接地调试人员的第一步工作也是最重要的一项工作是仔细检查接地,这项工作是保证节电装置可靠运行的关键,必须认真做好。

具体工作内容如下:1)检查主回路接线是否牢固可靠,尤其对QA空气开关、ON刀开关与Km接触器点接线有否松脱现象,如有松脱,必须拧紧。

2)检查面板背面各种电气器件,如电压表、电流表、指示灯按钮、转换开关的接点连线是否牢固可靠。

如有松脱,必须拧紧。

3)检查控制电路板,各点接线是否松动。

如有松脱,必须拧紧。

4)检查控制箱内控制电路板及电机供电的C45电源开关是否合上。

6、通电调试操作1)将面板上“手动”/“自动”选择开关(QT1)放置“手动”档位置。

2)ON刀开关置“稳压”位置。

稳压器处于空载状态,接通电源,合上空气开关QA,这时面板上的三相电源指示灯亮,输入电压表有读数,即完成输入电源通电试验。

3)按“稳定”按钮SB2,大约延迟5-15s后,延迟继电器KC5闭合使输出接触器KM得电闭合,机板上绿色“稳压”灯亮。

然后,根据输出电压表V0的读数,按“升压”按钮SB3或“降压”按钮SB4,输出电压表指针随之升或降,即完成手动调试试验。

注意事项:当按稳压按钮SB2后节电装置不能启动,相序保护器指示灯不亮,表示三相相序错接。

排除方法应先切断电源。

只要将三根进线中的任意两根线位置进行调换即可。

当按稳压按钮SB2后,稳压即有输出电压,但瞬间出现报警并自动跳闸保护,表示接线正确,由于输入电压偏高,输出电压也跟随偏高且高于电压保护值。

此时应将“手动”/“自动”选择开关(QT1)放置“自动”档位置。

再按稳压SB2。

观察输出电压表V0的读数稳压380V后,再进行4)操作,调试“升压”和“降压”两种情况下,节电装置是否稳压(380V)。

若出现异常请速与本厂联系。

4)将“手动”/“自动”开关放置“手动”档位置不变,然后按SB3“升压”按钮,使输入电压达到400V左右,把QT1开关转换到“自动”档位置,稳压器输出随之下降到380V左右,这是升压试验,将“手动”/“自动”开关放置“手动”档位置,然后接着按SB4“降压”按钮使输出电压为360V左右,把QT1开关转换到“自动”一档的位置,输出电压随至上升到380V左右。
