技术定义与适配语境
典型 母线排 会按材料、尺寸公差、适配关系和失效风险在 电气设备制造 中评估。

Bus bars are solid, flat, or tubular conductors made from high-conductivity metals, designed to carry and distribute high electrical currents with minimal voltage drop and heat generation. In inverter bridges, they connect power semiconductor devices (like IGBTs or MOSFETs) to form the DC link and AC output circuits, ensuring efficient power flow and structural stability.

定义
Bus bars are solid, flat, or tubular conductors made from high-conductivity metals, designed to carry and distribute high electrical currents with minimal voltage drop and heat generation. In inverter bridges, they connect power semiconductor devices (like IGBTs or MOSFETs) to form the DC link and AC output circuits, ensuring efficient power flow and structural stability.
工作原理
Bus bars operate on the principle of electrical conduction, providing a low-resistance path for current flow. In inverter bridges, they distribute DC power from the input source to switching devices and collect AC output, minimizing inductance and losses through optimized geometry and material properties.
材料
Copper (C11000C10100) or aluminum (60616063) with tinsilveror nickel plating for corrosion resistance and improved conductivity.
Insulation
Epoxy powder coating or heat-shrink tubing
Conductivity
>98% IACS for copper
Current Rating
100A to 5000A
Voltage Rating
Up to 1000V DC/AC
Temperature Range
-40°C to 150°C
标准
ISO 6722DIN 43671IEC 60439
