Technical Field

[0001] The utility model belongs to the technical field of measurement and control chassis, and in particular relates to a chassis for an electric power measurement and control device. Background Art

[0002] Measuring and control instruments are essential measurement tools for power systems and are indispensable for ensuring safe power operation. They provide information on the current status of circuits during safe power operation and prevent faults caused by overcurrent or short circuits. Multiple power measuring and control instruments are installed centrally, necessitating a power measuring and control chassis. However, existing power measuring and control chassis are often bulky, and the stacking of multiple measuring and control instruments results in poor internal heat dissipation. Utility Model Content

[0005] The upper and lower side walls of the cell cavity are provided with through-openings, and the through-openings pass through the bottom of the ventilation cavity. The upper baffle is equipped with an upper cover, and the middle part of the upper cover is provided with an arc ring, and a motor cover is provided above the arc ring. The edge of the arc ring is fixedly connected to the motor cover through a circular array of connecting rods. A cooling fan is fixed in the motor cover, and a surrounding net is provided between the connecting rods.

[0006] Preferably, side openings communicating with the side cavity are provided on both sides of the power box, and a ventilation duct is formed between the motor cover and the arc-shaped ring.

[0007] Preferably, the arc-shaped ring is inclined upward, and the edge of the motor cover extends over the arc-shaped ring and is located above the upper cover.

[0008] Preferably, the heat dissipation fan is an exhaust fan, and the ventilation cavity and the array of cells form an air filling channel, which flows to the side cavity below and is discharged from the side opening.

[0009] The beneficial effects of the utility model are as follows: the structure is simple, and after the measurement and control device is installed separately, each separated cavity can be cooled while being waterproof, with good cooling effect and strong practicality. The details are as follows:

[0010] (1) The utility model is provided with a grid cavity, and the power measurement and control instrument is installed in the grid cavity. After installation, the display and operation of the front end of the power measurement and control instrument are located outside the grid cavity, and the four sides of the power box are sealed. When heat dissipation is carried out, the cooling fan is running, and the air flow enters the grid cavity from the through-hole at the bottom of the ventilation cavity, passes through the grid cavities in the vertical column, enters the side cavity from the through-hole of the lowest grid cavity, and is discharged from the side port above the side cavity, thereby completing the circulation of the air flow in the grid cavity, and there are partition cavities between the grid cavities to avoid poor heat dissipation of the stacked power measurement and control instruments.
