Preassembled environmentally friendly ring main unit

Abstract

The application relates to the technical field of ring network boxes, and discloses a preassembled environment-friendly ring network box, which comprises an outer box and a plurality of preassembled inner boxes arranged in the outer box; a partition plate is arranged in the inner box; the inner box is divided into a relay chamber, a mechanism chamber, a gas chamber and a cable chamber through the partition plate; the preassembled environment-friendly ring network box further comprises a gas circulation assembly; the gas circulation assembly is provided with a plurality of gas distribution covers; the plurality of gas distribution covers are respectively installed on one side of the plurality of inner boxes and are communicated with the gas chamber; the gas circulation assembly is communicated with the plurality of inner boxes through a backflow pipe, a connecting pipe and the gas distribution covers; the inert gas in the gas chamber can be circulated and flows to achieve heat dissipation of the gas chamber; a heat dissipation assembly is connected in series on the backflow pipe of the gas circulation assembly; and the inert gas is cooled through the configured radiator. The preassembled environment-friendly ring network box solves the problems that in the prior art, heat dissipation, air supplement and condensation prevention are separated, lack of cooperation and mutual complementation, and the low heat conduction characteristic of the environment-friendly gas cannot be deeply adapted.
