Problems solved by technology
[0003] The existing overheating protection structure of the distribution box is not convenient enough for the heat dissipation of the circuit components, and the overheating position cannot be accurately judged. It can only control the overall temperature of the distribution box. Circuit components dissipate heat, resulting in waste of power resources

One or more embodiments of this specification propose a power distribution box with an overheating protection structure, including a box body, an air supply assembly is installed on the top of the box body, and a Main air supply duct, several component air supply ducts are installed on both sides of the main air supply duct, and several air outlets are opened on the sub-air supply duct, the sub-air supply duct and the main air supply duct An on-off assembly is installed between them, a temperature measuring assembly is installed on one side of the sub-air supply pipe, several groups of on-off assemblies are installed on the main air supply pipe along its vertical direction, and the side of the box body is installed With an exhaust port, the power distribution box proposed in one or more embodiments of this specification, through the cooperation of the on-off component and the switch component, can realize the heat dissipation of the local high-temperature part, thereby improving the accuracy of temperature control, and at the same time Energy is also saved, and at the same time, the entire distribution box can be dissipated as a whole, which improves the efficiency of temperature control.
Description
technical field [0001] One or more embodiments of this specification relate to the field of distribution box technology, in particular to a power distribution box with an overheat protection structure. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. The load provides protection, monitoring and control, but the existing distribution cabinets have the following disadvantages: [0003] The existing overheating protection structure of the distribution box is...
