以进口特殊不锈钢合金材料，开发生产的系列不锈钢中性接地电阻柜装置。变压器中性点接地电阻柜对降低电网过电压、提高电网的安全性、可靠性，具有良好的效果。用于 6～35kV电缆供电系接地电容电流较大的系统中。当接地电流大于规定值时，有可能产生弧光接地过电压。中性点采用电阻接地方式的目的就是给故障点注入阻性电流，其电阻分量电流可以把故障电流限制得适度，提高继电保护灵敏度，把暂态过电压限制到正常相对中性点电压的2.6倍，防止弧光过电压损坏主设备，同时对铁磁谐振过电压有显著作用。

To import special stainless steel alloy materials, development and production of the series of ark of stainless steel neutral grounding resistance device. Useful - B transformer neutral point grounding resistance tank to reduce the over-voltage of power grid, improve power grid security, reliability, and has a good effect. For 6 ~ 35 kv cable power supply system grounding capacitive current is larger in the system. When the grounding current is greater than the specified value, may produce arc grounding overvoltage. Neutral resistance grounding mode is the purpose of sex is to the point of failure into resistance current, the resistance component of the current can limit the fault current very moderate, improve the sensitivity of the relay protection, limit the transient over-voltage to normal relatively neutral point voltage of 2.6 times, prevent damage of over-voltage of arc light main equipment, at the same time has significant effect to ferroresonance overvoltage. 

产品特点

Product features 

　　1.电阻柜柜体材质采用不锈钢板，外型美观，耐腐蚀性强，防护等级可达IP55。

1. Resistance ark cabinet put oneself in another's material is made of stainless steel plate, good appearance, strong corrosion resistance, protection grade reaches IP55. 

　　2.根据不同的使用条件，电阻柜分为户内型和户外型。进线方式可采用上进下出、侧进下出、和下进上出等，采用上进下出、侧进下出时柜体顶端装有穿墙套管。柜体顶部装有吊环便于吊装。
