Description

Technical Field

[0001] This utility model relates to the field of low-voltage power distribution technology, specifically to a three-proof modular low-voltage power distribution tapping device. Background Technology

[0002] Low-voltage distribution tap changers are devices used to tap, branch, connect, and switch circuits in cable lines. Primarily used outdoors, they can split a single cable into multiple branch cables or merge multiple cables into a single main cable, enabling flexible cable connection and distribution. They are widely used in cable distribution systems in urban power grids, industrial parks, residential communities, and other locations, allowing for flexible cable connection and distribution and improving power supply reliability.

[0003] In the existing technology, when a low-voltage power distribution tap changer malfunctions, the circuit in which the tap changer is located will not be able to work normally. It is only after maintenance personnel repair it that the circuit in which the tap changer is located can work normally, which affects the reliability of power supply. Moreover, existing low-voltage power distribution tap changers are prone to internal corrosion, which poses certain safety hazards. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a three-proof modular low-voltage power distribution tapping device.

[0005] The technical solution of this utility model is: a three-proof modular low-voltage power distribution tapping device, including an equipment box, an installation component installed inside the equipment box, electrical components installed on the installation component, and a tapping component installed on the installation component and capable of connecting to the electrical components;

[0006] The mounting components include a first carrier plate disposed inside the equipment enclosure and a second carrier plate disposed inside the equipment enclosure and symmetrical about the first carrier plate;

[0007] Several electrical components are provided, and the electrical components are equidistantly distributed on the opposite side of the two second carrier plates. Each electrical component has a first terminal block at its top and a second terminal block on its outer side wall.

[0008] Several tap changer assemblies are provided, and each tap changer assembly is equidistantly distributed on the first carrier plate. Each tap changer assembly includes a switching seat on the first carrier plate, an insulating sliding seat that is slidably engaged with the switching seat, and a conductive copper busbar that passes through the insulating sliding seat. A through slot is provided on the second carrier plate at a position corresponding to the conductive copper busbar. A lever is provided on the insulating sliding seat that is slidably engaged with the switching seat.

[0009] Furthermore, the equipment box has a hinged door at the front end, and an observation window is provided on the door;

[0010] Each of the two second carrier plates is equipped with a mounting slide rail on the side that is far apart from each other, and each electrical component is slidably engaged with each mounting slide rail in a one-to-one correspondence.

[0011] Note: The enclosure door facilitates maintenance of the electrical components inside the equipment enclosure, and the mounting rails connect the electrical components to the second carrier plate, making it easy to install the electrical components.

[0012] Furthermore, a moisture-proof box is installed at the bottom of the equipment box, which is connected to the inside of the equipment box and is filled with a desiccant.

[0013] Explanation: The desiccant absorbs water molecules that enter the equipment enclosure, keeping the inside of the enclosure dry at all times. This not only improves the operational reliability of electrical components but also prevents corrosion and damage to the equipment enclosure.

[0014] Furthermore, a vent is provided at the rear of the equipment box, and several vent louvers are evenly distributed inside the vent. Each vent louver has a small gear at both ends. Racks that mesh with the corresponding small gears are slidably engaged on both sides of the inside of the equipment box. The bottom ends of the two racks are connected to a return spring that abuts against the inner wall of the equipment box. A dustproof plate is movably hinged at the rear of the equipment box outside the vent. Push rods that are movably hinged on both sides of the dustproof plate are respectively connected to the two racks.

[0015] Explanation: The dustproof plate can prevent external dust from entering the equipment box, while the ventilation louvers help to dissipate heat from the electrical components inside the equipment box. When the dustproof plate is subjected to external pressure, the push rod pushes the rack to slide inside the equipment box. Since the rack is connected to the pinion, the ventilation louvers rotate and close the ventilation holes.

[0016] Furthermore, each through slot is rotatably engaged with a relay conductive plate; the second carrier plate is rotatably engaged with a knob connected to the relay conductive plate;

[0017] Explanation: By rotating the knob, the second terminal block and the conductive copper busbar are connected using the relay conductive plate, which facilitates the replacement of damaged electrical components and ensures the reliability of the equipment's power supply.

[0018] Furthermore, each of the second terminal blocks has elastic contact pieces on both sides inside that can abut against the relay conductive plate at the corresponding position;

[0019] Note: When the relay conductive plate enters the second terminal block, the two elastic contacts are in close contact with the relay conductive plate, thus ensuring the reliability of the equipment.

[0020] The working principle of this utility model is as follows:

[0021] In use, each electrical component is plugged into the mounting rails on the second carrier plate; the relay conductive plate on one of the second carrier plates is rotated so that one end of the relay conductive plate contacts the second terminal block on the electrical component, and then the insulating sliding seat is moved inside the switching seat by the toggle block so that the conductive copper busbar contacts the other end of the relay conductive plate; the first terminal block on each electrical component is connected to the external input cable, and each conductive copper busbar is connected to the output user cable; when an electrical component fails and needs to be replaced, the insulating sliding seat is moved inside the switching seat by the toggle block so that the conductive copper busbar conducts to the relay conductive plate on the other second carrier plate; during equipment operation, silica is used to adsorb water molecules entering the equipment box, keeping the inside of the equipment box dry at all times, and the dustproof plate is used to block external dust from entering the equipment box, while the ventilation louvers help to dissipate heat from the electrical components inside the equipment box; when the dustproof plate is subjected to external pressure, the push rod pushes the rack to slide inside the equipment box, and since the rack is meshed with the pinion, each ventilation louver rotates and closes the ventilation holes.

[0022] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0023] First, the structure of this utility model is reasonably designed. By setting two sets of electrical components inside the equipment box and using a tap switch assembly to enable free switching between the two sets of electrical components, the circuit can work normally when maintenance personnel repair faulty electrical components, thus ensuring the reliability of the equipment's power supply.

[0024] Secondly, by setting ventilation holes and dustproof plates on the side wall of the equipment box, this utility model can improve the heat dissipation effect of the equipment box, creating favorable conditions for the reliable operation of the electrical components inside the equipment box; at the same time, by using desiccant to adsorb water molecules that enter the equipment box, the inside of the equipment box is kept dry at all times, which can avoid corrosion and damage to the equipment box and extend the service life of the equipment box.

[0025] Third, the electrical components and tap changer of this utility model are modularly installed inside the equipment box, which improves the layout flexibility and compactness of the electrical components inside the equipment box; saves internal space of the equipment box and realizes the miniaturization of the equipment box.

[0036] like Figure 1 , 3 As shown in Figure 4, there are 10 electrical components 3. The 10 electrical components 3 are equidistantly distributed on the side of the two second carrier plates 21 that are far apart from each other.

[0038] Example 2

[0041] Example 3

[0042] The difference between this embodiment and Embodiment 2 is that:

[0043] like Figure 1 As shown, a moisture-proof box 12 is provided at the bottom of the equipment box 1. The moisture-proof box 12 is connected to the inside of the equipment box 1. The moisture-proof box 12 is filled with a desiccant. The desiccant is a product of existing technology, such as attapulgite desiccant.

Since the rack 61 is meshed with the pinion 60, each ventilation louver 6 rotates and closes the ventilation hole 13.
