Description

Technical Field

[0001] The utility model relates to the field of electronic voltage regulators, in particular to a heat dissipation and dustproof three-phase electronic voltage regulator for low voltage management. Background Art

[0002] The three-phase voltage regulator can adjust and stabilize the input grid voltage to ensure that the output voltage remains within the set range. In areas where the grid voltage fluctuates greatly, the use of a three-phase voltage regulator can effectively protect power equipment and prevent damage to the equipment caused by excessively high or low voltage.

[0003] A search revealed that in the prior art, Chinese patent publication number CN220173088U discloses "a drying oven for a three-phase AC voltage regulator. This drying oven for a three-phase AC voltage regulator comprises a current limiting sleeve mounted on the outside of the three-phase AC voltage regulator housing, with the current limiting sleeve being fixedly mounted on the inner side of the housing close to the top, and a sealing block on the sealing plate. This prevents humid air from entering the inner cavity of the housing through the exhaust holes when the housing is not in use, thereby ensuring that the interior of the housing is dry while reducing energy consumption." However, the following defects still exist:

[0004] (1) While protecting the voltage regulator, the voltage regulator is completely closed, which lacks heat dissipation for the voltage regulator, and easily leads to excessive internal temperature and unstable use effect;

[0005] (2) At the same time, the internal voltage regulator lacks dust protection, which easily leads to dust accumulation inside, causing inconvenience in use and poor heat dissipation.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] See Figures 1 to 6 , the utility model provides a technical solution:

[0036] A heat dissipation and dustproof three-phase electronic voltage regulator for low voltage management includes a voltage regulator body 1, a shell 2 is provided on the periphery of the voltage regulator body 1, a heat dissipation mechanism 3 is provided on one side of the shell 2, a dustproof component 4 is provided on one side of the shell 2, a cooling component 5 is provided on one side of the heat dissipation mechanism 3, and an observation component 6 is provided on the top side of the shell 2;

[0038] Specifically, such as Figure 3 As shown, the dustproof component 4 includes a mounting groove 401, an arc plate 402, a dustproof plate 403 and a clamping block 404. The mounting groove 401 is opened on the inner side of the shell 2, one end of the arc plate 402 is set at the mounting groove 401, one end of the dustproof plate 403 is welded to the top end of the arc plate 402, and the clamping block 404 is fixedly set at the bottom end of the arc plate 402.

When external dust enters the shell 2, it will first be blocked by the dustproof plate 403. The blocked dust slides along the dustproof plate 403 to the arc plate 402. When it accumulates on the arc plate 402 to a certain extent, the arc plate 402 can be pulled out to clean the dust on it. At the same time, the heat dissipation fan 302 is interconnected with the external power supply to blow air to dissipate heat inside.

[0045] By setting up a cooling component 5, water is passed through the water inlet pipe 502, and the water is cooled by the cooling plate 501. The cooling fan 302 blows cold air into the shell 2 to cool the voltage regulator body 1. At the same time, the cooled water is finally discharged from the water outlet pipe 503. The internal situation can be observed and operated through the observation port 601, and the shell 2 can be closed by additionally installing a cover plate through the matching groove 7 on one side.
