摘　　要：针对多根小线径高压线束并线穿过霍尔传感器的台架试验场景,因高压线间电流相互干扰及屏蔽层影响会导致总电流检测精度产生一定偏差。通过设置集成霍尔电流环的高压接线盒能够有效保证电流检测精度;且该方法兼顾多根高压线并用时的散热优势,同时可避免采用新的大截面高压线带来的成本增加。Aiming at the bench test scenario where multiple small diameter high-voltage harnesses passing through Hall sensors in parallel,the total current detection accuracy may deviate due to the mutual interference between high-voltage wires and the influence of shielding layers.The high-voltage junction box with integrated Hall current loop can effectively ensure the current detection accuracy,which takes into account the heat dissipation advantage of using multiple high-voltage lines simultaneously and meanwhile avoids the cost increase caused by the use of new large cross-section high-voltage lines.
