常见问题
贵司的电阻柜和负载箱可达多少 kW 额定?
标准柜体尺寸单台 5 kW 至 5 MW,多柜并联可达 20 MW 用于电网级发电机测试。电压等级 400 V、690 V、6.6 kV、11 kV、33 kV。阻值按您的测试规程(连续、阶跃、斜坡)定制。标准尺寸矩阵见 /products/resistor-box。
有哪些端子类型和接线方式可选?
电阻柜可配铜母排(M10/M12 螺柱)用于固定安装,或绝缘 Cam-Lok(J 系列,每相 400 A)用于便携测试设备。双母排可达更高电流(连续 1500 A)。端子按 IEC 60446 色标(棕/黑/灰 + 黄绿接地)。室外使用可选 NEMA 3R 防风雨端子箱。
电阻柜是否适合户外或船用环境?
标准柜为 IP23(室内防护)。户外使用可选 IP54 百叶柜(防雨防尘)和 IP65 全密封内置热交换器。船用级采用 316 不锈钢外壳与环氧涂层端子,按 IEC 60068-2-52 通过盐雾测试。工作温度环境 −40°C 至 +55°C;可选热带防护(TH)涂层。
电阻柜可以有多个抽头或可编程阻值步进吗?
可以 —— 常见配置包括手动选择开关(5–10 个固定抽头)、电动接触器组(2–256 个二进制编码步进,通过 Modbus RTU 或 Ethernet/IP)、以及伺服驱动滑片连续可变。十进制盒式样带 0.1 Ω 分辨率至 1 MΩ 也可供实验室计量使用。告知您的控制接口和步进分辨率以获取定制报价。
全定制电阻柜的交期是多久?
典型交期 6–10 周:1 周工程评审和 CAD 确认,4–6 周钣金加工、电阻元件组装和接线,1 周高压、负载测试和老化,加 1–2 周海运。50 kW 以下项目可加急 4 周交付(加价)。发邮件至 [email protected] 附单线图和目标交货日期获取报价。
