Description

Technical Field

[0001] The utility model relates to the technical field of automatic voltage regulators, in particular to a high-precision fully automatic voltage regulator. Background Art

[0002] An automatic AC voltage regulator is composed of a contact type autotransformer regulator, a servo motor, an automatic control circuit, etc. When the grid voltage is unstable or the load changes, the automatic sampling control circuit sends a signal to drive the servo motor to adjust the position of the carbon brush of the autotransformer regulator, so that the output voltage is adjusted to the rated value and reaches a stable state. The three-phase high-precision fully automatic AC voltage regulator is a combination of the performance of SVC series single-phase products.

[0003] However, the problem that the existing automatic voltage regulator is inconvenient to maintain during use, making it inconvenient for workers to perform disassembly and assembly operations, resulting in a long maintenance cycle and affecting the use effect and overall work process of the automatic voltage regulator has not been solved yet. For this reason, we propose a high-precision fully automatic voltage regulator. Summary of the Utility Model

[0004] In view of the above problems, the utility model provides a high-precision fully automatic voltage regulator, which has the effect of being convenient for disassembly and assembly, preventing inconvenient operation during the maintenance of the automatic voltage regulator, and at the same time has the effect of improving heat dissipation, preventing poor heat dissipation, resulting in heat accumulation inside the automatic voltage regulator and affecting the service life.

[0005] The technical solution of the utility model is: a high-precision fully automatic voltage regulator, including an automatic voltage regulator housing, a protective door and an automatic voltage regulator body. The protective door is hinged to one side of the automatic voltage regulator housing. The automatic voltage regulator body is arranged inside the automatic voltage regulator housing. Installation plates are fixedly connected to both the upper and lower sides of the automatic voltage regulator body. A support plate that fits with the lower installation plate is provided on the bottom surface of the inner wall of the automatic voltage regulator housing. Slide rails fixed to the bottom surface of the inner wall of the automatic voltage regulator housing are provided on both sides of the support plate. A sliding block fixed to the support plate slides inside the slide rails. The slide rails are used to drive the support plate to move in cooperation with the sliding block.

[0006] In a further technical solution, heat dissipation grooves are formed in the lower surface of the automatic voltage regulator housing. A plurality of uniformly distributed heat dissipation holes are formed in the outer surface of the automatic voltage regulator housing. The heat dissipation holes communicate with the inside of the heat dissipation grooves. A plurality of uniformly distributed installation grooves are formed in the bottom surface of the inner wall of the automatic voltage regulator housing.

[0007] In a further technical solution, limit rods fixed to the inner wall of the automatic voltage regulator housing are provided on both sides of the upper installation plate.

[0008] In a further technical solution, a limiting block fixed to the mounting plate is sleeved on the surface of the limiting rod, and the contact surface between the limiting block and the limiting rod is smooth and fitted.

[0009] In a further technical solution, the installation slot is communicated with a heat dissipation slot, and a heat dissipation fan is fixedly connected in the installation slot.

[0010] In a further technical solution, a plurality of evenly distributed heat dissipation holes are provided on both sides of the surface of the automatic voltage stabilizer housing.

[0011] The beneficial effects of the utility model are:

[0012] 1. The support plate, slide rail and sliding block cooperate with each other, so that the automatic voltage stabilizer housing can be conveniently maintained when in use. The automatic voltage stabilizer body and the mounting plate are pulled by holding the support plate to move. At this time, the slide rail can move within the sliding block to limit the position, which achieves the effect of easy maintenance and prevents the automatic voltage stabilizer housing from being inconvenient to maintain after the automatic voltage stabilizer body and the mounting plate are placed, affecting subsequent operations;

[0013] 2. The heat dissipation slots, heat dissipation holes, mounting slots and heat dissipation fans cooperate with each other to improve the heat dissipation effect of the automatic voltage stabilizer housing when in use. The heat dissipation fan is electrically started, and then the heat dissipation fan generates suction, so that air enters the heat dissipation slots through the heat dissipation holes. At this time, the air enters the automatic voltage stabilizer housing to dissipate heat energy, thereby achieving the effect of facilitating heat dissipation and preventing poor heat dissipation, which may easily lead to damage to the automatic voltage stabilizer body and mounting plate.

[0020] The embodiments of the present utility model will be further described below with reference to the accompanying drawings.

[0021] Embodiment:

[0022] As Figures 1-4 shown, a high-precision full-automatic voltage regulator includes an automatic voltage regulator housing 1, a protective door 2 and an automatic voltage regulator body 3. The protective door 2 is hinged to one side of the automatic voltage regulator housing 1, and the automatic voltage regulator body 3 is arranged inside the automatic voltage regulator housing 1. Installation plates 4 are fixedly connected to both the upper and lower sides of the automatic voltage regulator body 3. A support plate 5 that fits with the lower installation plate 4 is provided on the bottom surface of the inner wall of the automatic voltage regulator housing 1. Slide rails 6 fixed to the bottom surface of the inner wall of the automatic voltage regulator housing 1 are provided on both sides of the support plate 5. A sliding block 7 fixed to the support plate 5 slides in the slide rails 6. The slide rails 6 are used to cooperate with the sliding block 7 to drive the support plate 5 to move. Limit rods 8 fixed to the inner wall of the automatic voltage regulator housing 1 are provided on both sides of the upper installation plate 4. A limit block 9 fixed to the installation plate 4 is sleeved on the surface of the limit rods 8. The contact surface between the limit block 9 and the limit rods 8 is in smooth fit.

[0023] The working principle of the above technical solution is as follows:

[0024] When it is necessary to remove the entire automatic voltage regulator body 3 for maintenance, first, the protective door 2 can be held by hand and flipped into an unfolded state. Then, the support plate 5 can be held by hand to apply force to drive the sliding block 7 to move. At this time, the sliding block 7 can move in the slide rails 6. The designed support plate 5 can drive the automatic voltage regulator body 3 to move outside the automatic voltage regulator housing 1. At the same time, the provided limit rods 8 can, when the automatic voltage regulator body 3 and the installation plate 4 move, make the upper installation plate 4 be limited by the limit block 9, preventing dislocation, achieving the effect of convenient maintenance and preventing the components inside the automatic voltage regulator body 3 and the installation plate 4 from being damaged and making it inconvenient to disassemble and assemble the automatic voltage regulator housing 1, resulting in great inconvenience in maintaining the automatic voltage regulator body 3 and the installation plate 4.

[0025] In another embodiment, as Figure 2 and Figure 4 shown, a heat dissipation groove 10 is formed in the lower surface of the automatic voltage regulator housing 1. A plurality of uniformly distributed heat dissipation holes 11 are formed in the outer surface of the automatic voltage regulator housing 1. The heat dissipation holes 11 are communicated with the inside of the heat dissipation groove 10. A plurality of uniformly distributed installation grooves 12 are formed in the bottom surface of the inner wall of the automatic voltage regulator housing 1. The installation grooves 12 are communicated with the heat dissipation groove 10. Heat dissipation fans 13 are fixedly connected in the installation grooves 12. A plurality of uniformly distributed heat dissipation holes 14 are formed on both sides of the surface of the automatic voltage regulator housing 1.

[0026] When it is necessary to improve the heat dissipation effect inside the automatic voltage regulator housing 1, first, the cooling fan 13 can be electrically connected to operate so that the cooling fan 13 generates suction, enabling the air outside the heat dissipation holes 11 to enter the heat dissipation grooves 10 under the suction of the heat dissipation grooves 10 in cooperation with the cooling fan 13. At this time, the air in the heat dissipation grooves 10 can be guided by the cooling fan 13 into the automatic voltage regulator housing 1. Through the entry of air, the heat energy inside the automatic voltage regulator housing 1 is pushed. At this time, the heat energy can be exported to both sides through the heat dissipation holes 14, thus being exported from the automatic voltage regulator housing 1, achieving the effect of improving heat dissipation and preventing the situation that when the automatic voltage regulator housing 1 is used for a long time or in hot summer, the internal heat dissipation effect is poor, resulting in heat accumulation and affecting the service life of the automatic voltage regulator housing 1.

[0027] The above embodiments only express the specific implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation to the patent scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
