压验电器在验电时，应该在电容器组上验电应待其放电完毕后再进行；7.对同杆塔架设的多层电力线路进行验电时，先验低压、后验高压，先验下层、后验上层。对高压验电器使用完毕后，应及时的将表面尘埃擦拭干净，并且放在干燥通风的地方进行妥善保管，一般不建议有强烈振动或冲击，并且对于高压验电器不准私自的对其进行随意的调整拆装，并且，为了保证其使用安全，一般会每隔半年就要进行预防性电气试验，这是十分必要的。
Use of large logarithmic communication cable in HYV and HSYV: it is mainly used for transmitting audio, 150kHZ and below analog signals and 2048kbit/s and below digital signals. Under certain conditions, it can also be used to transmit digital signals over 2048kbit/s. WeChat sales department is newly added in our factory. WeChat ID: TLDLC1 QQ is not convenient for WeChat contact! HYV, HSYV indoor large logarithmic communication cable is introduced: SPC switching station MDF and exchange between users of audio connection, also can be used for other audio connections between communication e, can support the low rate of data transmission, application support voice, digital telephone, fax, program-controlled switches, digital e connection, telecom integrated system and main branch line, inner conductor wire diameter (mm) : 0.40, 0.50, 0.60, 0.70, 0.80, 0.90, logarithmic (on) : 10-500 type broadband/product use: It is applicable to the transmission system from the remote optical network unit to the user and the subsystem of the transmission between buildings in the building wiring system. The highest transmission fre are 30MHz and 100MHz respectively.

从事电气操作的人员（广大电工朋友），经常与各种电路打交道，不是进行照明电路就是进行动力控制电路的安装和维护。什么全压启动、减压启动等各种控制电路全不在话下，操作起来更是得心应手。但是不知大家想过没有，我们进行各种控制电路安装维护时，都是有现成的控制图纸来指导我们进行操作的，这些控制电路都是设计人员精心设计出来的。我们常用的经典电路，在操作时也是想当然的按图操作，丝毫不怀疑图纸会出现什么问题。那么这些经典的控制电路为什么要这样设计？设计原则是什么？有什么特点？估计大家都没有认真的思考过这个问题。
