TDS笔使用说明概述水质电解器也叫固体沉淀促进仪，是美国食品医药管理局（F.D.A），认定用来对已经被污染的水进行基本判定的简易的水质检测方法，对于需要检验水源纯净时很有实际意义，可使用户清楚、直观地看到自己日常所饮用水的实际情况。
使用方法1、准备检验水——取两只容量为100～150毫升的白色玻璃杯，一杯接自来水，另一杯接RO机水，并排放在桌子上。
2、准备检验——将电解器平放于玻璃杯上，插上220伏电源。
3、检验——将电解器上的电源开关按钮按向ON（开）的位置，开始检验。
通常检验的时间为30秒。
结束时，先将电源开关按向OFF（关）的位置，最后取出电解器。
安全警告接通电源后，双手不得抓在电极上；不得将手指伸入检验水中；不要让儿童玩耍电解器。
电解器用完后，应用干布将电极擦干，并用细纱布将铁质极杆上的水擦净，并妥善保管。
说明该测试仪不能被用来评价矿泉水品质，因为在用其测量矿泉水时，水中的矿物质也可能会与水中的其它污染物发生一些化学反应，会给用户带来误判。
这种仪器带有正负两极的电解棒（一个是铁棒，一个是铝棒），即作为电场引入的两个电极。
电解器通电以后，在电流的作用下，溶解出正价的Fe3+离子，他们会与水中负价的OH-离子结合，形成不溶于水的Fe(OH)3微粒，这些微粒对水中胶体粒子的凝聚和吸附活性很强，并由此形成对水中有机或无机物的吸附、凝聚过程。
同时，由于电流的作用，原来溶于水中的金属粒子，如锰、钾、钴等还原出来，并逐渐聚集形成金属团，由于不同金属离子的显色不同，从而产生颜色的分离。
电解后的水出现不同颜色显示出水中各类杂质水质电解仪黄色: 溶解酸素、硅化合物、有机矿物质、钼、硅、氟化物、其他有机物绿色: 砷（砒霜）、汞、铅、铜、钠蓝色: 细菌、病毒、致癌物质、有机磷等（化肥、洗涤剂和农药）红色: 铁及铁锈、细菌白色: 铅、锌、汞、无机盐污垢黑色: 重金属（锌、铅、铜、铬、锰、镉）水质电解仪电解水质检测仪单排（带皮套）、双排两种任选TDS 是英文 total dissolved solids 的缩写，中文译名为溶解性总固体，又称总含盐量，测量单位为毫克 / 升（ mg/L ） , 它表明 1 升水中溶有多少毫克溶解性总固体，或者说1 升水中的离子总量。

KG:1. General Customer ResponsibilitySome goods within the product range of Würth Elektronik eiSos GmbH & Co. KG contain statements regarding general suitability for certain application areas. These statements about suitability are based on our knowledge and experience of typical requirements concerning the areas, serve as general guidance and cannot be estimated as binding statements about the suitability for a customer application. The responsibility for the applicability and use in a particular customer design is always solely within the authority of the customer. Due to this fact it is up to the customer to evaluate, where appropriate to investigate and decide whether the device with the specific product characteristics described in the product specification is valid and suitable for the respective customer application or not.2. Customer Responsibility related to Specific, in particular Safety-Relevant ApplicationsIt has to be clearly pointed out that the possibility of a malfunction of electronic components or failure before the end of the usual lifetime cannot be completely eliminated in the current state of the art, even if the products are operated within the range of the specifications.In certain customer applications requiring a very high level of safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health it must be ensured by most advanced technological aid of suitable design of the customer application that no injury or damage is caused to third parties in the event of malfunction or failure of an electronic component. Therefore, customer is cautioned to verify that data sheets are current before placing orders. The current data sheets can be downloaded at .3. Best Care and AttentionAny product-specific notes, cautions and warnings must be strictly observed. Any disregard will result in the loss of warranty.4. Customer Support for Product SpecificationsSome products within the product range may contain substances which are subject to restrictions in certain jurisdictions in order to serve specific technical requirements. Necessary information is available on request. In this case the field sales engineer or the internal sales person in charge should be contacted who will be happy to support in this matter.5. Product R&DDue to constant product improvement product specifications may change from time to time. As a standard reporting procedure of the Product Change Notification (PCN) according to the JEDEC-Standard inform about minor and major changes.

电力电容器及无功补偿技术手册沙舟编著目录前言第一章基本概念 (1)§1-1 交流电的能量转换 (1)§1-2 有功功率与无功功率 (2)§1-3 电容器的串联与并联 (3)§1-4 并联电容器的容量与损耗 (3)§1-5 并联电容器的无功补偿作用 (4)第二章并联电容器无功补偿的技术经济效益 (5)§2-1 无功补偿经济当量 (5)§2-2 最佳功率因数的确定 (7)§2-3 安装并联电容器改善电网电压质量 (8)§2-4 安装并联电容器降低线损 (11)§2-5 安装并联电容器释放发电和供电设备容量 (13)§2-6 安装并联电容器减少电费支出 (15)前言众所周知，供电质量主要决定于电压、频率和波形三个方面。
电网频率稳定决定于电网有功平衡，波形主要决定于网络和负荷的谐波，电压稳定则决定于无功平衡。
当然三者之间也具有一定的内在关系。
无功平衡决定于网络中无功的产生和消耗。
在系统中无功电源有同步发电机、同步调相机、电容器、电缆、输电线路电容、静止无功补偿装置和用户同步电动机，无功负荷则有电力变压器，输电线路电感和用户的感应电动机，各种感应式加热炉、电弧炉等。
为了满足系统中无功电力的需求，单靠发电机、调相机、电缆和输电线路电容是不够的，静补装置中也是采用电容器等。
因此电容器在系统的无功电源中占有相当比重，加之调相机为旋转设备。
建设投资大，运行维护费用高。
近年来世界各国都积极装设电容器，满足系统无功电力要求，维持电压稳定。
但各国主要是装设并联电容器，装串联电容器者较少，因此编者主要介绍并联电容器无功补偿技术，它还广泛应用于谐波滤波装置，动态无功补偿设备和电气化铁道无功补偿装置之中，因与电力系统谐波有关。
限于篇幅，准备在“谐波技术”中详述。
这里主要介绍一些无功补偿技术基础。
限于编者水平，加上时间仓促，不当之处难免，请读者批评指正。
