[0002] Dynamic voltage regulators are common electrical devices used to stabilize AC power supplies. Currently, most dynamic voltage regulators require complete disassembly during maintenance to expose the internal components for repair. This method is inefficient and difficult, especially since equipment used in power distribution requires even higher maintenance efficiency. Therefore, existing dynamic voltage regulators need further improvement to enhance maintenance efficiency. Utility Model Content

[0019] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0020] Reference Figure 1-5As shown, this embodiment of a dynamic voltage regulator that is easy to maintain includes a housing 1, a flip-out door 2 connected to the housing 1, a voltage regulator unit installed inside the housing 1, and a switch unit installed in the housing 1. The voltage regulator unit is connected to the switch unit to open and close the output through the switch unit. An opening 11 is provided on one side of the housing 1, and a pull-out mechanism 3 is provided at the position corresponding to the opening 11. The voltage regulator unit is located on the pull-out mechanism 3, and the voltage regulator unit is brought out or brought into the housing 1 by the pull-out action of the pull-out mechanism 3.

[0021] During maintenance, operators can use the pull-out mechanism 3 to remove the component carrying the voltage regulator unit from the housing 1 through the opening 11, exposing the voltage regulator unit to the external space for inspection. After inspection, the pull-out mechanism 3 can be pushed back into the housing 1. This structure allows the connection between the voltage regulator unit and other components inside the housing 1, such as the switch unit, to be achieved through flexible cables or connectors, maintaining or disconnecting necessary electrical connections during the pulling process, thereby improving maintenance convenience and efficiency. The opening / closing door 2 is used to expose or protect the switch unit by opening or closing it.

[0022] In order to facilitate the closure and protection of the top opening 11, in one alternative embodiment, the opening 11 is located on the upward side of the housing 1, and a removable or flip-up top cover 4 is provided on the side of the housing 1 corresponding to the opening 11. When the top cover 4 is closed on this side, the top cover 4 blocks the opening 11.

[0023] In normal operation, the top cover 4 closes on the upward-facing side of the housing 1, shielding the opening 11 and preventing dust or foreign objects from entering the housing 1. When maintenance is required, the top cover 4 can be flipped open or removed to expose the opening 11 for pull-out operation. The top cover 4 and the housing 1 are connected by hinges, clips, or bolts to achieve a flip-out or detachable connection, which improves the convenience of maintenance operations.

[0024] Specifically, further optimization can be achieved by selecting the following method: connecting ears 31 are provided on both sides of the top of the pull-out mechanism 3. After the pull-out mechanism 3 is inserted into the opening 11, the connecting ears 31 abut against the edge of the opening 11 of the housing 1 to provide support for the pull-out mechanism 3.

[0025] Once the pull-out mechanism 3 is inserted into place, the connecting ear 31 forms a supporting fit with the edge of the opening 11 of the housing 1, enabling the pull-out mechanism 3 to stably bear the weight of the voltage regulator unit and preventing the pull-out mechanism 3 from sliding excessively into the housing 1 or shifting during use. The connecting ear 31 and the main body of the pull-out mechanism 3 can be connected by integral molding or welding to ensure structural strength. This support structure improves the installation stability of the pull-out mechanism 3.

[0026] In some options, the connecting ear 31 is fastened to the housing 1 by fasteners.

[0027] The connecting lug 31 is fixedly connected to the housing 1 by fasteners such as bolts or screws, so that the pull-out mechanism 3 forms a stable rigid connection with the housing 1 in the working state, preventing the pull-out mechanism 3 from being displaced unexpectedly due to vibration or external force, and improving the reliability of equipment operation.

[0028] To improve heat dissipation performance, in one alternative, the bottom of the pull-out mechanism 3 is provided with a vent 32 for heat dissipation exhaust or air intake, and the housing 1 is provided with a window corresponding to the vent 32 for air to enter or leave.

[0029] The heat generated during the operation of the voltage regulator unit can be dissipated through the heat dissipation channel formed by the vent 32 and the window. External air can enter through the window, exchange heat with the voltage regulator unit through the vent 32, and then be discharged, or vice versa, thereby improving the heat dissipation efficiency and improving the working environment of the voltage regulator unit.

[0030] Specifically, further optimization can be achieved by selecting the following method: a ventilation grille 33 is provided on the side of the pull-out mechanism 3, and the housing 1 has a hollow structure 12 at least at the position corresponding to the ventilation grille 33. The two sides of the hollow structure 12 are bent into the housing 1 to form a guide structure 121. The guide structure 121 is adapted to the edge of the pull-out mechanism 3 to provide guidance for the pull-out action of the pull-out mechanism 3.

[0031] The ventilation grille 33 can form an air passage with the ventilation opening 32, which improves the heat dissipation effect; the guide structure 121 slides with the edge of the pull-out mechanism 3 during the pull-out process, providing guidance and limit for the reciprocating motion of the pull-out mechanism 3, making the pull-out action more stable and smooth, while the hollow structure 12 reduces the weight of the shell 1.

[0032] In some options, the bottom of the pull-out mechanism 3 is provided with several wiring ports 34, through which the voltage regulator unit is connected to or outputs power.

[0033] The wiring port 34 is used to realize the electrical connection between the voltage regulator unit and the external circuit or other electrical components inside the housing 1. It can be connected by plug-in terminals, aviation plugs or screw locking terminals, which improves the convenience of maintenance and the reliability of electrical connection.

[0034] In order to optimize the internal airflow organization, in one optional scheme, a partition 5 is provided inside the housing 1 between the pull-out mechanism 3 and the switch unit, and the switch unit is installed on the partition 5 to concentrate the air inlet and outlet directions.

[0035] The partition 5 divides the interior of the housing 1 into different functional areas. The switch unit is installed on the partition 5, which concentrates the airflow in the area where the pull-out mechanism 3 is located, reducing airflow turbulence and improving heat dissipation efficiency. It also facilitates the installation of the switch unit.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
