Abstract

The invention belongs to the technical field of electric power automation, and particularly relates to a mobile low-voltage intelligent bypass system which comprises a circuit breaker, a normally-open voltage relay, a first normally-closed voltage relay, a second normally-closed voltage relay and a first control switch. The primary side of the circuit breaker is connected with an operation power supply and a maintenance power supply; a secondary side is connected with the operation power supply; a coil of the normally-open voltage relay is connected in parallel with the output end of the operation power supply; the coil of the first normally-closed voltage relay and the coil of the second normally-closed voltage relay are connected in parallel with two ends of the maintenance power supply; and the output end of the operation power supply is sequentially connected with the first control switch, the second normally-closed voltage relay, the normally-open voltage relay and the first normally-closed voltage relay and then is connected with the circuit breaker. According to the invention, circuit breaker switching-on action logic judgment is realized, and automatic switching-on of the circuit breaker is realized too.

Description

technical field [0001] The invention belongs to the technical field of electric power automation, and in particular relates to a mobile low-voltage intelligent bypass system. Background technique [0002] Power outages of low-voltage users caused by distribution network failures, maintenance or engineering transformation will seriously affect the electricity demand of important electricity consumers, which is not conducive to the city's establishment of high-reliability demonstration power supply areas in core areas. [0003] Conventionally used power generation vehicles are transferred to power generation vehicles. When connecting and exiting power generation vehicles, power outages are required. At the same time, the operation noise is large, which seriously affects the daily life of nearby residents. Nakamura cannot enter, and the operation and maintenance costs such as fuel consumption, labor, and maintenance are relatively high. [0004] Zhejiang Electric Power Company...
