Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an aluminum alloy single-phase electric meter box. Background Technique

[0002] In the power field, as an important power equipment storage device, the performance and structure of the electric meter box are of great significance to the stable operation of the power system and the safe use of electric meters.

[0003] Traditional electric meter boxes often have some problems in the design and use process. For example, the heat dissipation performance is not good, and the internal heat accumulates after long-term use, which may affect the accuracy and service life of the electric meter. Moreover, the internal structure design is not reasonable enough, resulting in inconvenient installation and maintenance of the electric meter.

[0004] In terms of heat dissipation, some electric meter boxes do not have a dedicated heat dissipation device, or the effect of the heat dissipation device is not ideal, and the heat in the box cannot be discharged in time and effectively.

[0005] In terms of structural design, the installation method of the electric meter is not flexible enough to meet the installation requirements of electric meters of different specifications. At the same time, the material selection of traditional electric meter boxes may not be ideal enough to meet the requirements in terms of strength, corrosion resistance, etc. Content of the Utility Model

[0006] In order to solve the above problems and improve the performance and practicability of the electric meter box, the utility model proposes an aluminum alloy single-phase electric meter box, aiming to provide a better and more reliable electric meter box solution through a unique structural design and an innovative heat dissipation method.

[0007] In order to achieve the above purpose, the utility model provides an aluminum alloy single-phase electric meter box, which includes a box body and a base connected to the lower end of the box body. A plurality of mounting holes are arranged in a rectangular array on the back plate of the box body, and a plurality of mounting columns extending inward are protruded in a rectangular array on the back plate of the box body; a heat dissipation plate, a heat conduction plate and a mounting plate are sequentially mounted from the inside to the outside through the mounting columns; mounting rings for sleeving on the mounting columns are protruded on the upper and lower sides of the heat dissipation plate, the heat conduction plate and the mounting plate; a plurality of blowers corresponding to the mounting holes are embedded on the plate surface of the heat dissipation plate; a plurality of metal heat conduction strips are array-mounted in the frame body of the heat conduction plate; brackets for mounting electric meters are horizontally arrayed from top to bottom on the mounting plate; a cover body protruding on the back plate of the box body is arranged on the upper side of each mounting hole.

[0008] Preferably, the box body is a rectangular cavity structure with a hollow interior and an open front end. A door plate that can be opened and closed is installed at the open front end of the box body, and a plurality of ventilation holes are opened on the lower end surface of the box body; a support column is arranged between the base and the box body to leave a space between the base and the box body.

[0009] Preferably, four mounting holes are arranged in a rectangular array on the back plate of the box body, and covers are arranged at the upper ends of the mounting holes.

[0010] Preferably, four fans are embedded in the heat dissipation plate in a rectangular array, and the fans are installed corresponding to the mounting holes. One end of the fan is embedded in the mounting hole, and heat dissipation holes are also formed in the heat dissipation plate.

[0011] Preferably, the heat conduction plate is of a rectangular frame structure. Horizontal limiting plates are arranged in a horizontal array on both the upper and lower sides inside the frame of the heat conduction plate. Limiting holes penetrating horizontally are formed on one side corresponding to the limiting plates. Heat conduction strips are installed between every two limiting plates. The heat conduction strips are made of aluminum metal material, and fixing rods for fastening the heat conduction strips are installed horizontally through the limiting holes.

[0012] The beneficial effects of the utility model are as follows: 1. In the utility model, through a plurality of inwardly extending mounting posts arranged in a rectangular array on the back plate of the box body, and mounting rings protruding from the upper and lower sides of the heat dissipation plate, the heat conduction plate and the mounting plate, the installation and disassembly of each component are more convenient, which is beneficial to the later maintenance and overhaul work. For example, when the fan fails, it can be quickly replaced.

[0013] 2. The multiple mounting holes arranged on the back plate of the box body, in cooperation with the fans embedded in the heat dissipation plate, can accelerate the air circulation inside and outside the box body, quickly take away the heat, and avoid the failure of the electric meter due to overheating. For example, in the hot summer, in a high-temperature environment, the efficient heat dissipation system can always keep the temperature inside the electric meter box within a safe range, ensuring the normal operation of the electric meter. The sequential installation of the heat dissipation plate, the heat conduction plate and the mounting plate, and the metal heat conduction strips arranged in an array in the heat conduction plate can quickly conduct the heat generated by the electric meter, improving the heat dissipation efficiency. For example, during high-load power consumption periods, a large amount of current passes through the electric meter to generate more heat, and the good heat conduction performance can timely disperse the heat, ensuring the accuracy of the electric meter measurement.

[0014] 3. The box body, the base and the heat conduction strips made of aluminum alloy material have good strength, corrosion resistance and heat conductivity, and can be used stably for a long time. At the same time, on the premise of ensuring performance, the material cost and manufacturing difficulty are reduced. Description of the Drawings
