Abstract

The invention relates to a protection device for an outdoor power distribution cabinet. The protection device for the outdoor power distribution cabinet comprises a box body, wherein the bottom of the box body is a bottom plate, and the top is a top plate; a side wall is arranged between the top plate and the bottom plate; the box body is sequentially provided with an inner side heat insulation plate, a base layer wall body and an outer layer heat insulation plate from inside to outside; a steel reinforcement framework is arranged in the base layer wall body, and is connected to the inner layer heat insulation plate through inclined inserting wires; connecting inserting elements penetrate through the outer layer heat insulation plate; the first end of each connecting inserting element is sharp; a rear seat is arranged at the end surface of the second end of the connecting inserting element; after the base layer wall body is poured, the first ends of the connecting inserting elements are positioned inside the base layer wall body, and the second ends of the connecting inserting elements are positioned outside the outer layer heat insulation plate; barbs are also formed on the connecting inserting elements, and are positioned inside the base layer wall body; the box body is also provided with a nitrogen gas cylinder; an outlet of the nitrogen gas cylinder is provided with a gas outlet pipe; an electromagnetic valve is arranged on the gas outlet pipe, and is connected to a local controller; and the local controller is also connected with an oxygen concentration sensor.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and relates to a protection device for a power system, in particular to a protection device for an outdoor power distribution cabinet. Background technique [0002] The power distribution cabinet is an important part of the grid power transmission field, and plays an irreplaceable role in the entire grid power transmission and distribution system. Without a power distribution cabinet or if the power distribution cabinet cannot operate, the user end will not be able to obtain power from the grid. [0003] With the continuous development and development of the current infrastructure; the coverage area of ​​the power grid is becoming more and more extensive; the number of outdoor power distribution cabinets is also slowly increasing. Due to its long-term exposure to the natural environment, the outdoor power distribution cabinet is exposed to sunlight and the internal temperature is...
