一般来说厂家越早，技术越过关，品牌越响亮，所生产的产品质量相对会更可靠，可想而知，知名厂家好不容易建立起来的品牌效应不可能生产劣质产品来自毁名声。了解无纸记录仪的内部结构，一般有两类，一类是采用集成芯片，模块化设计，可靠，性能稳定，精度高，我公司的产品全通道单隔离；还有一类就是采用传统的手工方式焊接操作，元器件差，数据随温漂严重，精度等级差如0.5%或1%以上，通道之间无隔离干扰严重。询价格：许多客户在采购的时候，只要求低价格，其实这是不对的，一般来说，了解记录仪的一些参数了，如它的模块，精度，稳定性，隔离性，兼容性等，因为高质量的元器件，液晶屏等质量做为品质的差考。看外观：品牌的记录仪。

如市电电源或蓄电池电源，转换成满足设备要求的质量较高的直流电压（精电）。直流开关电源的核心是DC/DC转换器。因此直流开关电源的分类是依赖DC/DC转换器分类的。也就是说，直流开关电源的分类与DC/DC转换器的分类是基本相同的，DC/DC转换器的分类基本上就是直流开关电源的分类。直流DC/DC转换器按输入与输出之间是否有电气隔离可以分为两类：一类是有隔离的称为隔离式DC/DC转换器；另一类是没有隔离的称为非隔离式DC/DC转换器。隔离式DC/DC转换器也可以按有源功率器件的个数来分类。单管的DC/DC转换器有正激式（Forward）和反激式（Flyback）两种。双管DC/DC转换器有双管正激式（DoubleTransistorForwardConverter）。

继电器的触点有两种表示方法：一种是把它们直接画在长方框一侧，这种表示法较为直观。另一种是按照电路连接的需要，把各个触点分别画到各自的控制电路中，通常在同一继电器的触点与线圈旁分别标注上相同的文字符号，并将触点组编上号码，以示区别。继电器的触点有三种基本形式：1.动合型（H型）线圈不通电时两触点是断开的，通电后，两个触点就闭合。以合字的拼音字头“H”表示。2.动断型（D型）线圈不通电时两触点是闭合的，通电后两个触点就断开。用断字的拼音字头“D”表示。3.转换型（Z型）这是触点组型。这种触点组共有三个触点，即中间是动触点，上下各一个静触点。线圈不通电时，动触点和其中一个静触点断开和另一个闭合，线圈通电后。

即速度丝批准由国家和标准机构制造商/产品编号/系列中断能力作用一百多年前由爱迪明的丝用于保护当时昂贵的白炽灯，随着时代的发展，丝保护电子/电力设备不受过电流/过热的伤害，避免电子设备因内部故障所引起的严重伤害。工作原理当电流流过导体时，因导体存在一定的电阻，所以导体将会发热。且发热量遵循着这个公式：Q=0.24I2RT；其中Q是发热量，0.24是一个常数，I是流过导体的电流，R是导体的电阻，T是电流流过导体的时间；依此公式我们不难看出丝的简单的工作原理了。一种丝一种丝当制作丝的材料及其形状确定了，其电阻R就相对确定了（若不考虑它的电阻温度系数）。当电流流过它时，它就会发热，随着时间的增加其发热量也在增加。

空心线圈往往由漆包线均匀绕制在环形骨架上制成，骨架采用塑料、陶瓷等非铁磁材料，其相对磁导率与空气的相对磁导率相同，这是空心线圈有别于带铁心的电流互感器的一个显著特征。（3）铁心线圈式低功率电流互感器（LPCT）。它是传统电磁式电流互感器的一种发展。其按照高阻抗电阻设计，在非常高的一次电流下，饱和特性得到改善，扩大了测量范围，降低了功率消耗，可以无饱和的高准确度测量高达短路电流的过电流、全偏移短路电流，测量和保护可共用一个铁心线圈式低功率电流互感器，其输出为电压信号。两者的使用发展方向由于电磁式电流互感器存在的易饱和、非线性及频带窄等问题，电子式电流互感器逐渐兴起。电子式电流互感器一般具有抗磁饱和、低功耗、宽频带等优点。
