Outdoor power distribution cabinet with heat insulation function

Abstract

The present invention belongs to the field of power distribution device technology, and especially relates to an outdoor power distribution cabinet with a heat insulation function. A liquid coolant circulating pump is arranged below the power distribution cabinet; baffles extended downwards from the power distribution cabinet are arranged around the liquid coolant circulating pump; surfaces of base materials of the top plate and four sides of the power distribution cabinet body and the baffles extended downwards from the power distribution cabinet are coated with heat insulation insulating layers; and the power distribution cabinet is internally provided with a bend pipe, the bend pipe is extended from the bottom surface of the power distribution cabinet to the outer portion of the power distribution cabinet body to connect with the liquid coolant circulating pump to form a loop, and the bend pipe is made of thermally conductive and insulating materials. Compared to the prior art, thesurfaces of the matrix is coated with the heat insulation insulating layers to effectively block outside heat and reduce an influence of outside high temperature on the cabinet body in a high condition; and moreover, through cooperative usage of heat insulation and circulating cooling, the outdoor power distribution cabinet with the heat insulation function can effectively avoid influence of a high-temperature weather on the power distribution cabinet, can perform effective heat radiation in the power distribution cabinet and can ensure usage safety of devices and circuits in the power distribution cabinet.

[0002] The power distribution cabinet is an important device in the power system and the final equipment of the power distribution system. The power distribution cabinet is the general name of the motor control center. In the case of concentrated loads and many circuits, they distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring and control for the load. The power distribution cabinet is particularly important for the power system, so The safety of the power distribution cabinet is the focus of power distribution equipment. Therefore, in the prior art, in order to protect the equipment and circuits in the power distribution cabinet and prevent external damage, most of the power distribution cabinets in the prior art are sealed structure, which leads to poor heat dissipation of the power distribution cabinet when the power distribution cabinet is running at high load or the weather is hot, or the ambient temperature is high, resulting in failure of equipment and circuits in the power distribution cabinet, resulting in property loss, but most of the current The power distribution cabinet has a sealed structure, which leads to the fact that the power distribution cabinet used outdoors is not only affected by high-load operation, but also under the condition of long-term sunlight exposure, which may aggravate the poor heat dissipation performance of the power distribution cabinet, and the high temperature cannot be dissipated in time. To increase the probability of failure of equipment and circuits in the distribution cabinet, therefore, it is necessary to solve the technical problem of poor cooling effect of the existing outdoor distribution cabinets under hot conditions
