车辆和充电站之间接口的直流电压测量

可以通过受电弓为电动商用车快速充电。为此需要在（带活动受电弓的）外部基础设施系统和固定安装在车顶上的充电杆之间保持接触。选择该方法的主要原因在于，不用长时间停靠充电就能为车辆提供充足的能量保持运行，这对于城市公交车等固定线路的车辆来说是重要的优势。受电弓的多个充电点通常位于车辆行驶沿线的不同位置。
受电弓系统的直流电压越高，车辆的充电速度就越快。出于这个原因，并且为了获得更高的驱动功率，倾向于选择越来越高的电压。预期电压将高于 2000 V DC。用于监测和隔离这些电压的技术当然也必须跟上不断变化的需求。

主要应用事实

领域


用于受电弓充电的车载系统直流电压测量

应用


检查充电连接和与其他车载系统的连接

测量参数


电压高达 1500 V DC，输出标准信号 4-20 mA 或者 0-10 V DC

主要要求


紧凑的测量模块，空间需求是主要标准之一

电压测量的可靠性对确保车辆的可用性起着决定性作用

安全隔离高电压；短途客运领域的必要保护措施

用于受电弓充电的车载系统

应用说明

直流车顶配电箱包含检查充电连接和相应电压、以及与其他车载系统建立连接的组件。

应用的要求

由于直流车顶配电箱内的空间有限，电压监测和隔离解决方案不仅要性能出色、可靠性高，而且还要结构紧凑。

为何选择 Knick?
P42000D2 是一款紧凑型高压变送器，用于电压测量和高达 2200 V AC/DC 的连续隔离。外壳宽度仅 45 mm，非常适合于狭小空间中的应用。增益误差小于 0.3%，响应时间 T90 为 110 μs，截止频率为 5 kHz，能确保测量质量。
