描述
1.电气连接与保护
高压/低压适配：
支持DC 750V/1500V（地铁常用电压）或AC 25kV（干线铁路），具体需根据型号确认。
集成熔断器、断路器或浪涌保护器，防止过流、过压损坏设备。
信号传输：
若为控制回路元件，可能包含数字量/模拟量输入输出（I/O），用于传输开关信号、温度传感器数据等。
2.环境适应性
抗振动设计：
通过加固结构、减震橡胶等措施，适应轨道交通车辆运行中的高频振动（频率5-200Hz，加速度≤5g）。
宽温工作：
工作温度范围-40℃~+85℃，满足高寒地区（如北欧）或高温沙漠（如中东）运行需求。
防护等级：
IP67（防尘防水），防止灰尘、雨水侵入导致短路。
3.模块化与集成性
标准化接口：
采用DIN轨安装、螺纹连接或快插接头，便于快速更换或扩展。
支持并联/串联组合，适应不同车辆的电气架构。
轻量化设计：
使用铝合金外壳、工程塑料，重量较传统元件降低30%，符合轨道交通轻量化趋势。
1.Electrical connection and protection
High voltage/low voltage adaptation:
Supports DC 750V/1500V(common voltage used in subway)or AC 25kV(trunk railway).The specific needs to be confirmed according to the model.
Integrated fuses,circuit breakers or surge protectors to prevent overcurrent and overvoltage damage to the equipment.
Signal transmission:
If it is a control loop element,it may include digital/analog input and output(I/O),which is used to transmit switching signals,temperature sensor data,etc.
2.Environmental adaptability
Vibration-resistant design:
Through reinforcement of structures,shock-absorbing rubber and other measures,it can adapt to high-frequency vibrations during rail transit vehicles(frequency 5-200Hz,acceleration≤5g).
Wide temperature work:
The operating temperature range is-40℃~+85℃,meeting the operating needs of high-altitude areas(such as Nordic Europe)or high-temperature deserts(such as the Middle East).
Protection level:
IP67(dust-proof and waterproof),prevents short circuits caused by dust and rainwater invasion.
3.Modularity and Integration
Standardized interface:
DIN rail mounting,threaded connection or quick plug connector for quick replacement or expansion.
Supports parallel/series combination to adapt to the electrical architecture of different vehicles.
Lightweight design:
The use of aluminum alloy shells and engineering plastics has a weight of 30%lower than that of traditional components,which is in line with the trend of lightweight rail transit.
