Problems solved by technology

However, the outdoor distribution cabinet has no temperature control function
When exposed to the scorching sun, the internal temperature of the outdoor distribution cabinet is very high, and the electrical equipment in the outdoor distribution cabinet is prone to aging, resulting in a shortened service life of the electrical equipment in the outdoor distribution cabinet, especially in the southern region.

Embodiment 1

[0022] see figure 1 , an outdoor power distribution cabinet with intelligent temperature control function, including a negative temperature coefficient thermistor, a solar power generation system, a refrigerator and a power distribution cabinet body 5, and the negative temperature coefficient thermistor is distributed on the inner wall of the power distribution cabinet body 5 Above, the negative temperature coefficient thermistor, the solar power generation system and the refrigerator are connected in series in sequence. The solar power generation system includes a solar power generation panel 1, which is placed obliquely on the upper part of the shell of the power distribution cabinet body 5, and the refrigerator is located on the solar power generation panel 1. Between the body 5 of the power distribution cabinet, there is also a cold air pipe 3 connected to the refrigerator, and the cold air pipe 3 extends to the top of the inner space of the main body 5 of the power distrib...

Embodiment 2

[0025] In this embodiment, on the basis of Embodiment 1, further, a heat dissipation device is provided at the bottom of the side wall of the power distribution cabinet body 5 . The top of the internal space of the power distribution cabinet body 5 is provided with a cold air pipe 3. When the refrigerator starts to work, the refrigerator generates cold air and flows into the internal space of the power distribution cabinet body 5. At this time, the cold air is located in the internal space of the power distribution cabinet At the top, the hot air sits below the cool air. According to common knowledge, the specific gravity of cold air is greater than that of hot air. Therefore, by providing a cooling device at the bottom of the side wall of the distribution cabinet body 5, the cold air on the top can discharge the hot air from the cooling device to the distribution cabinet, forming effective air convection, and effectively reducing the internal temperature of the distribution c...

Embodiment 3

[0027] In this embodiment, on the basis of Embodiment 2, further, the heat dissipation device is a fixed louver 7 . The use of fixed louvers 7 as a heat dissipation device has the following advantages: (1) It can prevent external rainwater from intruding into the power distribution cabinet body 5, and avoid electrical accidents caused by rainwater intrusion; (2) It can block the strong sunlight outside and avoid sunlight Part of the electric equipment inside the power distribution cabinet causes the temperature of these electric equipment to rise, affecting normal operation; (3) The fixed shutter 7 can not only realize the heat dissipation function, but also have a more beautiful appearance. Other parts of this embodiment are the same as Embodiment 2 and will not be repeated here.

Abstract

The invention discloses an outdoor power distribution cabinet having an intelligent temperature control function. The outdoor power distribution cabinet includes a negative temperature coefficient temperature-sensitive device, a solar power generation system, a refrigerating machine, and a power distribution cabinet body, the negative temperature coefficient temperature-sensitive device is arranged on the inner wall of the power distribution cabinet body, the negative temperature coefficient temperature-sensitive device, the solar power generation system, and the refrigerating machine are successively and serially connected, the solar power generation system includes a solar generating board which is inclinedly arranged at the upper part of the casing of the power distribution cabinet body, the refrigerating machine is arranged between the solar generating board and the power distribution cabinet body, a cold air duct is connected with the refrigerating machine and extends to the top of inner space of the power distribution cabinet body, and the cold air duct of the inner space of the power distribution cabinet body is provided with a cold air window which opens downwards. The outdoor power distribution cabinet can intelligently control temperature to prevent electric power device from being damaged because over-high temperature; a cooling deice is arranged at the bottom of the side wall of the power distribution cabinet body to effectively reduce the inside temperature of the power distribution cabinet, and an induced draught fan is arranged in the cold air window to prevent local temperature from being too low.

Description

technical field [0001] The invention relates to the field of outdoor power equipment, in particular to an outdoor power distribution cabinet with an intelligent temperature control function. Background technique [0002] The electric power industry is a basic industry and public utility that supports national economic and social development. Since the reform and opening up, my country's economy has entered a period of rapid development, especially since the beginning of this century, the rapid development of industrialization, urbanization, marketization, and internationalization has driven the rapid growth of the power industry, and the trend is still strengthening. [0003] As an important power equipment in the power industry, the outdoor distribution cabinet has always been valued by people. However, the outdoor distribution cabinet does not have a temperature control function. When exposed to the hot sun, the internal temperature of the outdoor power distribution cabi...
