A self-radiating power distribution box for power engineering substations

Abstract

The invention proposes a self-radiating distribution box for power engineering substations, which includes a box body, the box body includes an inner box body and an outer box body arranged outside the inner box body, a temperature sensor is arranged in the inner box body, and the inner box body A first air duct is formed between the bottom end of the body and the bottom end of the outer box, multiple second air ducts are formed between the side wall of the inner box and the side wall of the outer box, and a plurality of second air ducts are formed between the top of the inner box and the top of the outer box. The third ventilation channel, a fan is arranged in the third ventilation channel; the bottom of the outer box body is provided with an air inlet connected with the first ventilation channel and its top is provided with an air outlet connected with the second ventilation channel, and the bottom of the inner box body There is a first vent communicating with the air inlet passage, and a plurality of second vents communicating with the second vent are provided on the side wall of the inner box, and a self-regulating vent is provided at the second vent. The invention can dissipate the heat in the distribution box to the air in time, thereby reducing the temperature in the distribution box and achieving a good heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a self-radiating distribution box for a power engineering substation. Background technique [0002] Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution box. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. The distribution box has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, not limited by the site, widely used, stable and reliable operation, high space utilization rate, less land occupation and environmental protection effect. [0003] Because the existing distribution box is in a sealed state, the heat dissipation is not good, it is easy ...

AI Technical Summary

Problems solved by technology

[0003] Because the existing distribution box is in a sealed state, the heat dissipation is not good, it is easy to make the temperature in the box exceed the normal operating temperature of the electrical equipment in the box, which affects the service life of the electrical equipment, and the sealed distribution box makes observation inconvenient and inconvenient data recording
