Description
The technical field is as follows:
the utility model relates to a high-voltage board structure field mainly relates to a do benefit to high-voltage board pressure release heat abstractor of heat dissipation and pressure release.
Background art:
in the operation process of the high-voltage cabinet, a primary circuit short circuit fault is caused by various reasons (such as short circuit, insulation aging, manual misoperation and the like), high-temperature high-pressure gas is generated instantly under the short circuit current of tens of thousands of amperes, if the high-temperature high-pressure gas cannot be effectively released in a short time in a narrow cabinet body, the high-voltage cabinet is cracked, adjacent high-voltage cabinets are damaged, and the personal safety is possibly hurt. Therefore, the structure of the high-voltage cabinet needs to be improved, so that the high-voltage cabinet meets the requirements of rapid heat dissipation and pressure relief.
The utility model has the following contents:
the utility model discloses the purpose is exactly in order to compensate prior art's defect, provides a high-voltage board pressure release heat abstractor who does benefit to heat dissipation and pressure release, and aim at has solved the problem that above-mentioned background art provided.
The utility model discloses a realize through following technical scheme:
the utility model provides a do benefit to high-voltage board pressure release heat abstractor of heat dissipation and pressure release, includes the lid, the middle part of lid is equipped with the trapezoidal boss of upwards arching, it has the louvre that the display interval set up to distribute on the side all around of trapezoidal boss, the louvre is the venetian blind formula louvre, the apron has been erect to the lid top, radiator fan is installed to the bottom of lid.
The cover body around the bottom end face of the trapezoidal boss is provided with a drainage groove, and the periphery of the cover body is also radially provided with a diversion groove which is communicated with the drainage groove.
The upper end surface of the trapezoid boss is a spherical boss which bulges upwards.
The inner side of the cover body is provided with vertical ribs which extend upwards and are distributed at intervals on the upper end face, the upper end parts of the vertical ribs are provided with connecting plates, and the connecting plates are provided with fixing holes which are fixedly connected with the cover plate.
The specification of the cover plate is larger than that of the cover body.
The heat dissipation fan works intermittently, is fixedly installed on the bottom end face of the cover body through the installation support, and the air outlet faces the heat dissipation holes.
The principle is as follows: through improving the lid structure, the design of trapezoidal boss has increased the internal space of cabinet when not influencing the internal each component assembly of cabinet, through the structure of louvre, can realize cabinet body top ventilation all around, be convenient for the internal heat dissipation of cabinet and the needs of pressure release, and through the mechanism of venetian blind formula, certain dustproof effect has, through radiator fan's design, the internal heat dissipation requirement of cabinet has been strengthened, its overall structure reasonable in design, when not only having increased the internal space of cabinet, supplementary heat dissipation has still been strengthened simultaneously, satisfy the requirement of quick heat dissipation and pressure release, the potential safety hazard of high-voltage board in the use has been solved.
The utility model has the advantages that:
the utility model has the advantages of reasonable design, when not only having increased the internal space of cabinet, still strengthened supplementary heat dissipation simultaneously, satisfied the requirement of dispelling the heat fast and pressure release, solved the potential safety hazard of high-voltage board in the use.

The specific implementation mode is as follows:
see the drawings.
The utility model provides a do benefit to high-voltage board pressure release heat abstractor of heat dissipation and pressure release, including lid (1), the middle part of lid (1) is equipped with trapezoidal boss (2) of upwards arching, and it has louvre (3) that the display interval set up to distribute on the side all around of trapezoidal boss (2), and louvre (3) are louver formula louvre, and lid (1) top is erect apron (4), and radiator fan (5) are installed to the bottom of lid (1).
Furthermore, the cover body around the bottom end face of the trapezoid boss (2) is provided with a drainage groove (6), the cover body (1) is radially distributed with a diversion groove (7), and the diversion groove (7) is communicated with the drainage groove (6). Through the structure of drainage groove, when the outside has rain, can be fine collect the box water conservancy diversion to the rainwater, avoid gathering at trapezoidal boss, one prevents to enter into the cabinet internal, when having realized the rainy day heat dissipation, avoids the rainwater to permeate the cabinet internal. The upper end surface of the trapezoidal boss (2) is a spherical boss which is bulged upwards. Through the structural design of the spherical boss, the flow conductivity of rainwater is ensured while the space structure of the spherical boss is not influenced.
Furthermore, the inner side of the cover body (1) is provided with vertical ribs (8) which extend upwards at intervals, the upper end of each vertical rib (8) is provided with a connecting plate (9), and the connecting plates (9) are provided with fixing holes which are fixedly connected with the cover plate (4). Through the structure of the vertical ribs, the heat conduction in the cabinet body is enhanced, and the cabinet body is gathered to the top to a greater extent, so that the heat dissipation and the pressure relief are facilitated. The specification of the cover plate (4) is larger than that of the cover body (1). Through the structure of apron, can shelter from the structure of lid upper end to avoid getting into sleet at sleet weather cabinet body upper end, influence the normal use of the cabinet body.
Furthermore, the heat dissipation fan (5) works intermittently, and is fixedly installed on the bottom end surface of the cover body (1) through the installation support (10), and the air outlet faces the heat dissipation hole (3). Through radiator fan's structure, can be at the internal temperature sensor who installs rather than the cooperation use of cabinet, when the internal high temperature of its cabinet, open radiator fan for the internal heat dissipation of cabinet and pressure release, thereby reached the more abundant rational utilization of resource.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
