Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to an improved box-type power distribution cabinet. Background Art

[0002] The improved box-type power distribution cabinet is an electric power distribution system that integrates multiple electrical components and equipment, and is used to control and distribute power supply. It is usually composed of a distribution cabinet or distribution board, circuit breakers, voltmeters, ammeters, contactors, fuses, control switches and other components, providing safe and reliable power distribution and control functions. Due to the excessive number of devices inside the cabinet, there will be a certain amount of power loss when the equipment is operating. These power losses will cause heat generation. If there are no proper heat dissipation measures, the heat will accumulate inside the distribution box, causing the temperature to rise, which may cause the equipment to overheat, affect the performance and life of the equipment, and even cause safety problems such as fire. Therefore, an improved box-type power distribution cabinet is now needed to solve the above problems.

[0003] After searching, the announcement number CN218386319U discloses a modular distribution box, which states: "The modular distribution box, through the mounting holes on the second mounting plate, facilitates the first threaded rod to initially fix the first rectangular frame through the second rectangular frame, and then slides the first rectangular frame inside the second rectangular frame to move the first mounting plate, and finely adjusts the first mounting plates to improve the utilization rate of the internal space of the box body, so as to solve the problem that the internal mounting plates of the existing distribution box are fixedly connected to the box wall during the production process, and it is inconvenient to adjust the mounting plates according to the size of the electrical components, resulting in low space utilization rate inside the distribution box and a large waste of resources."

[0004] However, the above-mentioned device has the following defects when in use: the above-mentioned distribution box is not provided with a heat dissipation mechanism. Since there are too many devices inside the combined distribution box, the power consumed during use will generate excess heat, causing the temperature inside the distribution box to rise, which will cause the equipment to overheat, affect the performance and life of the equipment, and even cause safety problems such as fire. In addition, the electrical equipment inside the distribution box will generate noise during operation, and the distribution box is usually located in industrial or commercial places, and there may be people working or living there, so the noise needs to be reduced.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By setting a heat dissipation mechanism, the solar panel converts solar energy into electrical energy, which is transmitted to the transformer through the power line. The transformer converts electrical energy from one voltage level to another voltage level. Through the transformer, the voltage of DC power can be converted into an appropriate AC voltage, and the current converted into AC voltage is transmitted from the transformer to the inverter. The inverter converts DC power into AC power. The AC power is transmitted to the battery protection board through the transmission line. The current passes through the battery protection board and is transmitted and stored inside the battery. The electrical energy stored in the battery supplies energy to the internal sensor, controller, and brake motor. The temperature sensor is used to detect the temperature inside the box. When the internal temperature is too high, the temperature sensor feeds back the information to the controller. The controller regulates the brake motor to brake the fan blades and dissipate heat to the internal heat sink group. The heat sink group conducts the heat generated by the internal components. The fan blades continuously dissipate heat to the heat sink group, and continuously dissipate the internal heat.

[0016] By setting up a vibration reduction device, vibration can be effectively absorbed and reduced, and noise can be reduced. The high-pressure spring set at the lower end of the box can absorb and disperse vibration energy and provide restoring force. When subjected to vibration or impact, the elastic element will deform, absorb energy, and release part of the energy back to the box by rebounding, thereby reducing the vibration inside the box. Protective ring 2. The protective ring is used to limit and support the rebound force of the high-pressure spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Working principle: When in use, the solar panel 501 first converts solar energy into electrical energy, and transmits it to the transformer 503 through the power line.
