High voltage power distribution device and high voltage power distribution coupling device

The utility model provides a high voltage power distribution device; isolation plates divide an inner space of an explosion-proof box into an isolation chamber, a main chamber, and a line outgoing chamber, so a voltage transformer and a breaker phase are isolated into different chambers and cannot interfere each other; a current transformer is arranged on a terminal so as to improve safety and reduce a man chamber space, so the explosion-proof box can be more compact, thus reducing the size of the explosion-proof box body; the breaker and other electric devices are more convenient in dismounting; in addition, the utility model also provides a high voltage power distribution coupling device.
