The utility model discloses a high-risk power consumption user emergency power supply connection structure, and belongs to an emergency protective circuit device. The connection structure comprises a series of bus units in series. Each bus unit comprises a bus and more than two load units. Each load unit comprises a power load device and a step-down transformer. The bus unit also comprises an emergency power supply device. The emergency power supply device is composed of a step-up transformer and a generator. The generator is connected with the bus through the step-up transformer. The generators of all the bus units are arranged in the same transformer station. The connection structure integrates original emergency power supply power supply devices which are distributed dispersedly, and thus the emergency power supply control mode is flexible. The connection structure can achieve direct power supply of the generators to the buses, the buses distribute power to important loads reasonably, thus the generator of each load device is standby for each other, the number of the generators is decreased, the cost is lowered, the starting time of the generators is shortened, and power supply reliability of an emergency power supply is raised.
