是防止在接地体的接地电阻达不到要求时、或者接地引下线与接体接触不良时接地引下线引起带电的情况下用的。重复接地就是在中性点直接接地的系统中，在零干线的一处或多处用金属导线连接接地装置。

It is used to prevent grounding when the earthing resistance of grounding body is not up to the requirement, or when the grounding lead off line and the contact body are not in good contact. The repeated grounding is the connection of the grounding device with a metal wire in one or more parts of the zero trunk line in a system directly grounded on the neutral point.

而中性点接地的系统中，一相接地后的接地电流较大（接近单相短路）保护装置迅速动作，断开故障点。等电位的含义也就是“将设备等外壳或金属部分与地线联结”。总等电位联结端子箱一般用于配电室内作重复接地用。

In the neutral grounding system, the grounding current after one phase is larger (close to the single-phase short circuit), the protection device moves quickly and disconnects the fault point. The meaning of the equipotential is "the connection of the shell or the metal part to the ground line". The general equipotential connection terminal box is generally used in the distribution room for repeated grounding.
