Working Principle 高压恒流电源产生的负高压，接入电晕极（阴极），它与沉淀极（阳极）之间产生电场，电场强度超过一定极限后在阴阳两极间即产生电晕放电。此时流经电场区的气体发生电离，产生大量的离子和电子。周围可听见强烈的电磁蜂声，光线暗时可见紫兰色电晕。通过电场的煤气中的焦油、粉尘、水雾等粒子与离子或电子结合而荷电，在电场力的作用下向两极运动。 The negative high voltage generated by the high-voltage constant-current power supply is connected to the corona polar (cathode), and an electric field is generated between it and the precipitation polar (anode). After the electric field strength exceeds a certain limit, a corona discharge shall be generated between the cathode and the anode poles. In this case, the gas flowing through the electric field area shall be ionized, and a large number of ions and electrons may be generated as well. Strong electromagnetic buzzing sounds can be heard around. Violet corona can be seen when the light is dark. Particles such as tar, dust, and water mist passing through the electric field are combined with ions or electrons to be charged, and move to the poles under the action of the electric field force. 由于电子质量小，运动速度快，空间分布广，所以主要是荷负电的粒子向沉淀极运动。到达沉淀极板中和后，依靠残存的静电引力和分子间凝聚力首先吸附于沉淀极，而后靠自身重力沿极板下落，通过焦油出口排出。 Due to the small mass of electrons, fast movement speed and wide spatial distribution, it is mainly that the negatively charged particles move towards the precipitation pole. After reaching the precipitation plate for neutralization, it is first adsorbed on the precipitation electrode by the residual electrostatic attraction and intermolecular cohesion, and then falls along the plate by its own gravity and is discharged through the tar outlet. 四、本体分类 IV.

Introduction of CS-Ⅲ-PLC Single-phase LC Constant Current Source 本产品由恒流源控制柜和高压发生器两部分组成。前者包括L-C恒流源①；继电和保护电路②；后者包括高压变电器③和硅整流桥④ This product consists of a constant current source control cabinet and a high voltage generator. The former includes L-C constant current source①; relay and protection circuit ②; the latter includes high voltage transformer ③ and silicon rectifier bridge ④ 电网U L-C恒流源 高压变压器 整流桥 本体电场 恒流调节和过氧控制电路 过压和持续欠电压保护电路 Grid U L-C Constant Current Source High Voltage Transformer Rectifier Bridge Electric Field of Unit Main Body Constant Current Regulation & Peroxygen Control Circuit Overvoltage & Continuous Undervoltage Protection Circuits 本产品由L-C组成的四端网络作为恒源流 ，在它的输出端可以获得与输入电压（网电压）成正比而与负载阻抗变化无关的电流。其输出电流和电网输入电流可分别用下式表达： This product consists of a four-terminal network composed of L-C as a constant source current. At its output, it can obtain a current that is proportional to the input voltage (grid voltage) and has nothing to do with the change in load impedance. Its output current and grid input current can be expressed by the following formulas: 式中a为复常数，b、c为实常数，Ui、Ii、和Uo、Io分别为输入（电网）电压、电流和输出（电场）电压、电流，RL为电场负载等效阻抗。 Where a is a complex constant, b and c are real constants, Ui, Ii, and Uo, Io are the input (grid) voltage, current, and output (electric field) voltage and current, and RL is the equivalent impedance of the electric field load. 由式（1）可知，输出电流仅与电网电压有关，而电网电压基本上可以认为是恒定的，从而Io恒定，这就是恒流的含义。 It can be known from formula (1) that the output current is only related to the grid voltage, and the grid voltage can basically be considered constant, so that Io is constant, which is the meaning of constant current. 当电场电晕转化为贯穿性击穿，即RL→0时，根据Uo=IoRL，有Uo→0,根据式（2），则有Ii→0。由于这种变化是同步的，即RL降低时，Uo同时降低，输入功率UiIi降低，电源提供给放电区的功率Io2RL随等效电阻RL同步线性下降，即闪络能量降低，故而电场击穿的概率比其它电源低得多。即使产生击穿，也能迅速恢复，无需长时间封锁电源。 When the electric field corona is transformed into penetrating breakdown, that is, RL → 0, according to Uo = IoRL, there is Uo → 0, and according to formula (2), there is Ii → 0. Because this change is synchronous, that is, when RL decreases, Uo decreases at the same time, input power UiIi decreases, and the power Io2RL provided by the power supply to the discharge area decreases linearly and synchronously with the equivalent resistance RL, that is, the flashover energy decreases. The probability is much lower than other power sources. Even if a breakdown occurs, it can be quickly recovered without the need to block the power for a long time. 对于可控硅电源输出电流Io由下式确定 For the thyristor power output current Io is determined by the following formula Io=Ii= 式中Σz为回路总阻抗，即电源的永久性阻抗，其值很小。 Where Σz is the total loop impedance, that is, the permanent impedance of the power supply, and its value is small. 由式（3）可知，一旦电场击穿或短路，即Uo→0时，Io和Ii都将显著增加，其值可达额定电流的几倍甚至几十倍，即时有反馈电路，击穿瞬间是不起作用的。此时电源提供的功率比正常工作时急剧增加，闪络或短路能量很大，极易形成电源本身或电晕线故障。 It can be known from formula (3) that once the electric field is broken down or short-circuited, that is, when Uo → 0, Io and Ii will increase significantly, and their values can reach several times or even dozens of times the rated current. There is a feedback circuit immediately, and the breakdown is instant Is not working. At this time, the power provided by the power supply increases sharply than during normal operation, and the flashover or short-circuit energy is very large, which easily causes the power supply itself or the corona wire to malfunction. 电晕功率 实线：恒源流供电特性 虚线：可控硅供电特性 从以上原理分析及放电特性图可知： 1、抑制电晕闭塞、阴极线肥大 设备在粉尘浓度增大时，会阻碍带电粒子的迁移，从而形成电晕“闭塞”。而恒源流在粉尘浓度增大时，输出电压会自动升高，可以有效的克服电晕“闭塞”,同时极板、极丝不易积灰，有效抑制阴极线肥大的发生。 2、恒源流火花放电功率远小于正常运行功率，对电除尘器机械缺陷不敏感，故可以将运行功率提至极限状态运行。 3、与恒源流负反馈放电特性相反，可控硅电源放电呈正馈特性，极易发展为火花放电，火花放电功率远大于正常运行功率，故而发生火花放电的频率高，能极大。为确保设备安全，只能在低电晕功率水平运行。 4、恒源流输入输出均为正弦波，输入阻抗呈阻性。经数学推导可得知U1与I1同相，因而功率因数较高。我公司企业标准COSΨ≥0.95接近1。而电压源的功率因数行业标准为COSΨ≥0.8，同样的设备如消耗的有功功率相同，则视在功率电压源要大的多。恒流电源节电效果明显。 六、CS-Ⅲ-PLC型单相LC恒流源主要特点 1.单相恒流高压电源柜采用西门子S7-200Smart系列PLC控制，有本柜和远程两种操作方式。电源的运行参数和指标通过PLC与DCS或上位机通讯，实现远程监控和启停。 2.、单相恒流高压电源柜采用西门子mart700IE，TFT触摸屏作为人机显示界面，全中文菜单操作，人机界面友好，实现实时、在线的自动显示测控； 3.采用人工智能控制，投运过程均按专家预设程序自动完成，无需人工干预，正确灵敏地在线实时监测工作状态。 4.工作方式为；（1）火花监测模式（2）基础工作模式； 5.通过上位机远程监控恒流源的运行状态，可实现恒流源的远程起动、停止、电压、电流、温度数据的实时监控，并能在设备出现开路、短路、过流、过压、过氧、温度超限等异常状态时远程切断电控柜电源，使用安全可靠。 6.实现对用户设备远程监控，实时了解现场的运行情况以及进行远程调试、诊断。 7.单相恒流高压电源柜源采用以太网通讯接口，可将电源柜与湿式电除尘DCS控制系统互连，通讯快速，实现远程操作，数据共享。 8.完善的保护功能当设备使用出现异常时，系统自动检测故障，发出声光报警并显示报警信息。当各绝缘箱的温度超过上下限定值时，发出报
