The destruction of a regular black hole event horizon might provide us the possibility to access regions inside black hole event horizon. This paper investigates the possibility of overcharging a charged Taub-NUT regular black hole via the scattering of a charged field and the absorption of a charged particle. For the charged scalar field scattering, both the near-extremal and extremal charged Taub-NUT regular black holes cannot be overcharged. For the test charged particle absorption, the result shows that the event horizon of the extremal charged Taub-NUT regular black hole still exists while the event horizon of the near-extremal one can be destroyed. However, if the charge and energy cross the event horizon in a continuous path, the near-extremal charged Taub-NUT regular black hole might not be overcharged.

常规黑洞事件视界的破坏可能为我们提供了访问黑洞事件视界内的区域的可能性。本文研究了通过带电场的散射和带电粒子的吸收使带电的Taub-NUT正黑洞过度充电的可能性。对于带电的标量场散射，近极和极极带电的Taub-NUT正黑洞都不能被过度充电。对于测试带电粒子的吸收，结果表明，极端带电的Taub-NUT规则黑洞的事件层仍然存在，而近极端的黑洞的事件层可以被破坏。但是，如果电荷和能量沿连续路径穿过事件范围，则接近极度带电的Taub-NUT常规黑洞可能不会被过度充电。
