Description

Technical Field

[0001] The utility model relates to the technical field of power supply box structures, in particular to a moisture-proof and corrosion-resistant power supply box. Background Art

[0002] The power supply box mainly provides operating power for vacuum circuit breakers and other high-voltage switches. The power supply box uses an input voltage of 220V or 380V, which is rectified by a thyristor voltage regulator, and outputs DC. It has the characteristics of outputting DC voltage with multiple gears and large current, or AC voltage, and performs single-open and single-close operations.

[0020] Reference Figure 1-3 The utility model provides an embodiment: a moisture-proof and corrosion-resistant power supply box, comprising a box body 1, a box door 2 is provided on the front side of the box body 1, a power board 3 is installed in the box body 1, heat dissipation mesh plates 4 are provided on both sides of the box body 1, a triangular bracket 5 is provided on the lower side of the box body 1, a rain shield 6 is installed on the upper side of the box body 1, a condensation mechanism 7 is installed on the inner wall of the box body 1, a connecting plate 8 is provided on the upper end of the box body 1, a galvanized metal box 9 is covered on the outer side of the box body 1, and the box door 2 is connected to the galvanized metal box 9. The galvanized metal box 9 here is galvanized by hot-dip galvanizing. Hot-dip galvanizing has a long durability, a high degree of industrialization in production, and stable quality. During operation, the first process of hot-dip galvanizing is pickling and rust removal, followed by cleaning. If these two processes are not thorough, they will leave hidden dangers for corrosion protection, so they must be handled thoroughly.

[0021] The door 2 is provided with a foam layer 21 in the wall thickness, a handle 22 is provided on the front side of the door 2, a door lock 23 is installed on the door 2, and the other end of the door lock 23 cooperates with the frame of the box body 1. The condensation mechanism 7 includes a condensation plate 71, a water collecting tank 72 is provided at the lower end of the condensation plate 71, and a water leakage hole 73 is opened at one end of the water collecting tank 72. The water collecting tank 72 is opened on the bottom end of the inner wall of the box body 1, and the condensation plate 71 is inclined at an angle of 60°. The galvanized metal box 9 is provided with a hole corresponding to the water leakage hole 73, which is convenient for draining the collected water. The front side of the power board 3 A control component 10 is installed, the condensation plate 71 is located in front of the control component 10 and is axially symmetrical in the box body 1, the condensation plate 71 is connected to the inner wall of the box body 1, the connecting plate 8 is connected to the galvanized metal box 9, and a water diversion groove 61 is provided on the rain shield 6, and the water outlet of the water diversion groove 61 is provided on the rear side of the rain shield 6. When rainwater drops on the power box, it is discharged backward along the water diversion groove 61, which will not affect the normal use of the power box. The triangular bracket 5 is connected to the bottom of the box body 1 by a screw 11, and the other end of the triangular bracket 5 is connected to the wall by a screw 11.

[0022] Working principle: First, the power box is fixed in a suitable position through the cooperation between the triangular bracket 5, the connecting plate 8 and the screws 11. When the power box is working, a large amount of water vapor will gather in the box body 1 due to external factors such as rain and low temperature. At this time, the condensation plate 71 condenses the water vapor in the box body 1 into small water droplets on the condensation plate 71. The water droplets flow into the water collecting tank 72 along the inclined direction of the condensation plate 71, and finally flow out of the box body 1 through the leakage hole 73, so as to achieve the moisture-proof effect, avoid moisture from causing short-circuit damage to the components in the power box, and enhance the safety of the power box. The outer side of the box body 1 is covered with a galvanized metal box 9, and the metal box is galvanized by hot-dip galvanizing. This method can make the service life of the metal box longer, effectively isolate the external erosion of the power box, extend its service life, and achieve the anti-corrosion effect.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
