变压器中性点接地电阻柜应用说明
变压器中性点接地电阻柜应用说明
Transformer neutral point grounding resistance ark application instructions
一、概述
An overview,
产的CT-DZ1系列变压器中性点接地电阻柜，该系列电阻器主要用于工厂、矿山、选煤厂等生产企业中660V供电系统变压器经电阻接地系统中。产品具有精度高，运行可靠，安装方便，外形美观等特点。
Shanxi narita electrical engineering co., LTD. series transformer
neutral point grounding resistance, the series resistor is mainly used
in factories, mines, coal preparation plant and other production
enterprises in the 660 v power supply transformer in the resistance
grounded system. Products with high precision, reliable operation, easy
installation, beautiful appearance, etc.
二、应用说明
Second, the application instructions
随着工矿企业机械化程度的提高，低压供电系统仍使用380V供电已不能满足发展的要求，为增加低压电网的输送能力，660V供电是一项非常值得推广的新技术，具有良好的社会效益和经济效益。
With the improvement of industrial and mining enterprises
mechanization degree, low voltage power supply system still use 380 v
power supply can not meet the requirements of development, in order to
increase the low voltage power grid transmission capacity, the 660 v
power supply is a very worthy of promotion of new technology, has the
good social efficiency and economic benefits.
660V供电系统与380V供电系统的区别在于，380V系统为变压器中性点直接接地的三相四线制系统，而660V系统为提高运行安全，变压器中性点应经电阻接地，并辅以漏电保护装置作为系统单相接地的保护，提高漏电保护的灵敏度。
660 v and 380 v power supply system of power supply system the
difference is that the 380 v system for transformer neutral point
grounding of three phase four wire system directly, and the 660 v system
to improve the operation safety, transformer neutral point grounding
resistance, shall be supplemented by the leakage protection device as
the single-phase grounding protection system, improve the sensitivity of
leakage protection.
My company produces the CT - DZ1 grounding resistance ark is mainly
used in the above introduction transformer neutral point of the 660 v
system through the resistance grounding system. Product shell according
to the different needs of users, stainless steel or cold rolling steel
plate production, beautiful appearance, corrosion resistance. Resistance
element (Cr20Ni80) with nickel chromium alloy materials, small
temperature coefficient and resistance stability.
