Problems solved by technology

[0003] The current problems of ring network cabinets used in areas with large temperature differences between day and night are complex installation structures, high costs, and low efficiency. Some special ring network cabinets need to be arranged in special occasions, such as areas with large temperature differences between day and night. At this time, the outside temperature during the day is extremely high, while the outside temperature at night is extremely low. Such a large temperature difference is not conducive to the normal operation and service life of the electrical components in the ring main unit, and is inconvenient for people to use.

Abstract

The invention discloses a ring main unit used in areas with high diurnal temperature variation, which comprises a shell, a heat insulation layer, a processor, an automatic lifting device and a radiating fan. The heat insulation layer is arranged on the inner side of the shell, and the heat insulation layer is connected to the shell by pasting. The automatic lifting device is arranged on the lowerside of the radiating fan. A main control box is arranged on the inner side of the shell, and the main control box is equipped with the processor. A wire is arranged between the processor and the automatic lifting device and the radiating fan. Because of the use of the automatic lifting device and the radiating fan, the ring main unit has a simple installation structure and high efficiency. When the ring main unit works in daytime, the automatic lifting device lifts the radiating fan, and the radiating fan discharges the heat in the ring main unit, so that the damage of the ring main unit is prevented, and the working efficiency of the ring main unit is improved. Because of the use of the heat insulation layer, when the ring main unit works at night, the automatic lifting device automatically drops, the heat insulation layer keeps the ring main unit warm, and thus, the service life of the ring main unit is improved.

Description

Technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to a ring network cabinet used in areas with large changes in temperature between day and night. Background technique [0002] The Ring Main Unit is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into an assembling bay ring network power supply unit. Its core part uses load switches and Fuse, it is widely used in distribution stations and box-type substations of load centers in urban residential districts, high-rise buildings, large public buildings, factories and enterprises. [0003] The current ring network cabinets used in areas where the temperature difference between day and night changes greatly, the installation structure is complicated, the cost is high, and the use efficiency is low. Some special ring network cabinets need to be arranged in special occasions, such as...
