Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, in particular to a power distribution cabinet for a nuclear power station. Background Art

[0002] A nuclear power plant is a facility that converts nuclear energy into electrical energy through appropriate devices. A nuclear power plant uses a nuclear reactor to replace the boiler of a thermal power plant. Nuclear fuel undergoes a special form of "combustion" in the nuclear reactor to generate heat, which converts nuclear energy into thermal energy to heat water and produce steam. Power distribution cabinets are usually used inside nuclear power plants. Power distribution cabinets are a type of distribution cabinet. Distribution cabinets are a general term for motor control centers. Power distribution cabinets are the final equipment of the distribution system except for lighting distribution cabinets and metering cabinets.

[0004] But the device still has the following defects:

[0005] Most of the existing power distribution cabinets dissipate heat for the electrical components in the distribution cabinet through heat dissipation holes. Since natural ventilation dissipates heat inside the cabinet through the flow of gas, the heat exchange rate between the cold air outside and the hot air in the distribution cabinet is slow, resulting in a low heat dissipation effect for the electrical components in the distribution cabinet, making the electrical components in the distribution cabinet prone to damage.
