Automatic heat dissipation and fire extinguishing device for outdoor transformer box

Abstract

The invention relates to the technical field of electric power and discloses an automatic heat dissipation and fire extinguishing device for an outdoor transformer box. The device comprises a box body, first rotating shafts are movably connected to the interior of the box body, first connecting rods are fixedly connected to the exteriors of the first rotating shafts correspondingly, first gears are fixedly connected to the inner side of the box body, and second gears are engaged to the exteriors of the first gears correspondingly. A second connecting rod is movably connected to the exterior of each second gear. Third connecting rods are movably connected to the ends, away from the corresponding second gears, of the second connecting rods correspondingly. Shells are fixedly connected to the exteriors of the third connecting rods correspondingly. A driving shaft is movably connected into each shell. Through the interaction among ratchet wheels, bimetallic strips, conductors, coils, clamping rods, second rotating shafts, third gears, fourth gears, dry powder chambers and switch assemblies, fire on an electric appliance element or a wiring position in the box body can be extinguished in time, so that electric appliances and the like in the box body are prevented from being seriously damaged by fire combustion; and influences of faults of the transformer box on the life of residents and enterprise production are reduced.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an automatic heat dissipation and fire extinguishing device for an outdoor transformer box. Background technique [0002] A transformer box is a box in a power system where the voltage and current of electric energy are exchanged, concentrated and distributed. [0003] Due to the universal application of electric energy, the continuity of power supply has become the guarantee of people's life. However, due to the large changes in electricity consumption in different regions and time periods, the work load of the substation box is large, and there is often a phenomenon of overloading the substation box. In this way, the electrical components inside the transformer box will cause accidents due to aging or short circuit, resulting in the loss of public property, and the electrical components inside the transformer box will generate a lot of heat when they work for a long tim...
