Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a power distribution cabinet that is protected against overheating. Background Technology

[0002] Distribution cabinets are the final-level equipment in a power distribution system. They are mainly used to distribute electrical energy to lower-level distribution points or various power consumption points. Distribution cabinets are not only the core equipment for power distribution, but also have multiple functions such as fault handling, safety protection, and intelligent monitoring. They are an indispensable and important component of modern power systems.

[0003] During the use of the power distribution cabinet, commands need to be issued through the electrical components installed inside the cabinet. However, under long-term use, the electrical components of the existing power distribution cabinet will generate heat due to the flow of current. Moreover, the power distribution cabinet only dissipates heat through heat dissipation slots, which easily causes heat to accumulate inside the cabinet and cannot be passively dissipated, resulting in overheating of the electrical components and affecting normal use.

At this time, the mounting compartment 24 is engaged in the mounting plate 23, so that the holes of the connecting hole 28 and the plug hole 29 are aligned. The supporting force applied by the support spring 25 pushes the partition 26 against the inside of the mounting compartment 24 and pushes the plug 27 into the plug hole 29 to realize the installation of the frame 2. When the distribution cabinet is in use, start the motor on the cooling fan 21 to drive the fan blades to rotate, thereby blowing the heat generated by the electrical components 12 out of the cabinet 1 through the heat dissipation groove 13.

[0036] When covering the cooling fan 21 inside the frame 2, first insert the protective net 3 into the connecting groove 31 and slide it on the surface of the limiting plate 32. Then, place the connecting plate 33 against the outer surface of the frame 2 so that the threaded block 34 passes through the through hole 35 through the surface of the connecting plate 33. At this time, the worker holds the screw ring 37 and aligns the inside of the nut 36 with the threaded block 34. Then, rotate the screw ring 37 so that the nut 36 is connected to the threaded block 34 through the thread and is pressed against the surface of the connecting plate 33 after tightening, so as to realize the installation and fixation of the connecting plate 33, thereby installing and fixing the protective net 3 on the surface of the frame 2 and playing a protective role.
