高压电网是一种有效的地面防御工事,常常成为阻挡地面部队进攻的障碍。然而,具有钢铁身躯的坦克却可以顺利地闯过高压电网,为地面部队开路。为什么坦克敢闯高压电网,难道坦克兵就不怕触电? 其实,坦克这种超常的“本领”是由导体的电学特性所决定的。现代主战坦克的车体、履带都是由钢铁制成的,其又宽又长的两条履带成了良好的接地点,坦克的身躯也就成了一个接地的空心导体,外界的电场不会影响腔内的物体。因此,当坦克接近高压电网时,坦克的钢铁壳体起了良好的屏蔽作用,使坦克内部的电场强度减弱到人体能够承受的程度,坦克兵当然就安然无恙了。
The high-voltage grid is an effective ground defense and often serves as an obstacle to offensive ground forces. However, a tank with a steel body can successfully pass through the high-voltage power grid to open the ground forces. Why tanks dare to break into high-voltage power grid, are not afraid of the tank soldiers electric shock? In fact, the tank of this extraordinary “skill ” is determined by the electrical properties of the conductor. Modern main battle tank body, tracks are made of steel, and its wide and long two tracks have become a good grounding point, the tank's body will become a hollow ground conductor, the external electric field is not Will affect the cavity objects. Therefore, when the tank is close to the high-voltage grid, the steel shell of the tank plays a good shielding role, so that the electric field strength inside the tank is weakened to the extent that the human body can bear. The tank soldier certainly is safe and sound.
