Emergency portable generator grid-connected and off-grid control cabinet

Technical Field

The utility model relates to an electric power construction field specifically is a portable generator is incorporated into power networks and off-grid control cabinet for emergency.

Background

The generator grid-connected cabinet is a power complete cabinet which is used for connecting a generator and a mains supply line, controlling the power output of the generator to be merged into the mains supply line to supply power to power consumers (grid connection) and disconnecting the power connection (off-grid) of the generator and the mains supply line;

with the development of socio-economy, power consumers have made higher demands on the continuity of power supply. Particularly in some industries or consumer equipment, a continuous supply of electricity is required. When a power supply unit carries out line maintenance construction, if a mains supply line needs to be disconnected, a movable power generation device such as a generator car is used as a temporary alternative power supply to supply power to power consumers, and after the construction is finished, the movable power generation device is removed from the line, and the mains supply is recovered. The generator grid-connected cabinet used by a power supply unit in the electric power maintenance construction needs to be connected with commercial power lines of different power users at different time and places;

the existing power generator grid-connected cabinet is mostly a fixed complete cabinet, is installed in a switching station and a distribution substation room, and is fixedly connected with the output of a power generator and a mains supply circuit.
