The invention relates to a dual-power 10KV power distribution device, and the device consists of two same distribution cabinets. Each distribution cabinet comprises an incoming wire isolation cabinet, an electricity metering cabinet, an incoming wire circuit breaker cabinet, a voltage transformation lightning arrester cabinet, a plurality of same outgoing wire cabinets, a plurality of standby outgoing wire cabinets, a first high-voltage busbar, and a second high-voltage busbar. The interior of the incoming wire isolation cabinet is provided with an incoming wire isolation circuit, and the interior of the electricity metering cabinet is provided with an electricity metering circuit. The interior of the incoming wire circuit breaker cabinet is provided with an incoming wire circuit breaker circuit, and the interior of the voltage transformation lightning arrester cabinet is provided with a voltage transformation lightning arrester circuit. The interior of each outgoing wire cabinet is provided with an outgoing wire circuit, and the circuit in each standby outgoing wire cabinet is the same as the outgoing wire circuit in each outgoing wire cabinet. Compared with the prior art, the device is simple in structure, is convenient in operation and maintenance, is high in work efficiency, is safe and reliable, lays emphasis on environment protection, and saves the resources.
