Outdoor power distribution cabinet

Abstract

The invention discloses an outdoor power distribution cabinet, comprising a cabinet body, wherein the front end of the cabinet body has two cabinet doors, an electrical cavity is arranged inside the cabinet body, four positioning guide rods are vertically arranged on the bottom surface of the electric cavity, the roots of the four positioning guide rods are fixedly installed with a power distribution board, the power distribution board is provided with an electronic component on one side opposite to the cabinet doors, the four positioning guide rods are slidably provided with sliding guide sleeves respectively, and both sides of each sliding sleeve are provided with a fixed portion respectively. The invention adopts a new heat dissipation structure to replace the self-contained heat dissipation system of the power distribution cabinet, utilizes the external airflow to achieve uniform heat dissipation of the internal power distribution board, is capable of effectively absorbing heat andblocking the oxygen near the heat source when the temperature is too high for effective flame retardant, and is capable of injecting inert gas into the whole cabinet during short-circuit fire to cutoff the internal combustion conditions, thereby better protecting the entire power distribution cabinet, and enabling safer use.

Description

technical field [0001] The invention relates to an outdoor power distribution cabinet. Background technique [0002] Outdoor power distribution cabinets generally use an independent heat dissipation system. The traditional heat dissipation system generally consists of a motor and fan blades. This structure itself generates heat. However, the heat dissipation system is arranged on the top or the bottom, and can only dissipate heat on one side, and its own heat dissipation performance is relatively poor. [0003] In addition, the heat dissipation system in the prior art has poor heat dissipation performance for the components on the internal main board, and it is easy to accumulate heat inside. Excessive internal heat can easily cause short-circuit spontaneous combustion of internal components. Spontaneous combustion generally occurs under continuous high temperature conditions. That is, when a certain component is always in a high temperature state, if it is not cooled, spon...

The heat dissipation system is set on the top or bottom, and can only dissipate heat on one side, and its own heat dissipation performance is relatively poor.

[0003] In addition, the heat dissipation system in the prior art has poor heat dissipation performance for the components on the internal main board, and it is easy to accumulate heat inside. Excessive internal heat can easily cause short-circuit spontaneous combustion of internal components. Spontaneous combustion generally occurs under continuous high temperature conditions. That is, when a certain component is always in a high temperature state, if it is not cooled, spontaneous combustion is likely to occur next. In the prior art, an alarm system will be set up to detect the problem of spontaneous combustion, but the alarm can only notify the fire and not Can't stop the fire source immediately
