Problems solved by technology
Existing power distribution cabinets generally have a number of heat dissipation holes on the end surface of the top plate. The heat dissipation holes lead to poor gas fluidity and often lead to slow heat dissipation, so that the heat of the power distribution cabinet is always in a state of accumulation. The components inside the power distribution cabinet will be affected and the working state will be unstable; at the same time, the existing power cooling plate structure is poor in compression and shock absorption, and the power components located on the installation base may be damaged due to the vibration of the installation base. cause loosening

The invention discloses an anti-seismic power distribution cabinet with good ventilation and heat dissipation properties. The anti-seismic power distribution cabinet comprises a base, square supporting frames, lower stand columns, elastic sleeves, a mounting plate, cabinet bodies, a top plate and circuit boards, wherein the square supporting frames are symmetrically arranged on the base from left to right; the lower stand columns are mounted in the square supporting frames; the cabinet bodies are fixedly mounted at the upper ends of the lower stand columns; upper stand columns are fixedly mounted at the upper parts of the cabinet bodies; the top plate is arranged above the upper stand column; the mounting plate is arranged between the cabinet bodies; fixing grooves are symmetrically formed above the mounting plate; the fixing grooves are internally provided with the circuit boards, heat conducting plates and heat dissipation plates; the tops of the circuit boards, the heat conducting plates and the heat dissipation plates are clamped by clamping rods; and the clamping rods are mounted on the inner surfaces of the upper ends of the cabinet bodies. The anti-seismic power distribution cabinet is simple in structure and good in ventilation and heat dissipation property, and also has good compression-resisting and anti-seismic properties and has very high popularization value.
Description
technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to an anti-seismic distribution cabinet. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets and metering cabinets, and are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. Existing power distribution cabinets generally have a number of heat dissipation holes ...
