Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to an intelligent power distribution cabinet. Background Technology

[0002] In modern power systems, intelligent distribution cabinets, as core equipment for power distribution and control, undertake the crucial tasks of receiving, distributing, controlling, and protecting electrical energy. They are widely used in various sectors, including industry, commerce, and residential applications, and their stable operation directly impacts the security and reliability of the power supply. However, during the operation of intelligent distribution cabinets, the internal electrical equipment generates heat. If this heat cannot be dissipated in time, leading to excessively high temperatures inside the cabinet, it can not only affect the performance and lifespan of the electrical equipment but may even cause safety accidents. Therefore, effectively controlling the temperature inside the distribution cabinet has become an urgent problem to be solved.

[0003] Existing cooling methods mostly employ fixed cooling structures, installing cooling fans at a constant speed inside the cabinet to cool the air through forced airflow circulation. However, a fixed fan speed cannot dynamically match actual cooling needs, easily leading to energy waste or insufficient cooling.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide an intelligent power distribution cabinet. The cabinet temperature is monitored in real time by a temperature sensor. The controller dynamically adjusts the speed of the first ventilation fan and the opening status or degree of the louver valve according to the temperature signal, and combines the second ventilation fan to assist in heat dissipation, thereby achieving precise and constant temperature control inside the power distribution cabinet and improving operational stability and reliability.

[0006] Technical Solution: This utility model provides an intelligent power distribution cabinet including a cabinet body and double doors mounted on the cabinet body; a controller, ventilation components, and a temperature sensor. The controller is mounted on the upper side of the cabinet body, the ventilation components are mounted on both sides of the cabinet body, and the temperature sensor is mounted on the inner side wall of the cabinet body. The temperature sensor is signal-connected to the controller. The ventilation components include a pair of louvered valves and a pair of first ventilation fans, respectively mounted on both sides of the cabinet body. The controller dynamically maintains a constant temperature inside the power distribution cabinet by adjusting the first ventilation fans and adjusting the opening or closing or the opening degree of the louvered valves. When the temperature rises, the controller increases the speed of the ventilation fans and widens the opening degree of the louvered valves to increase the air intake and airflow velocity for rapid heat dissipation. When the temperature drops, the controller reduces the speed of the ventilation fans and decreases the opening degree of the louvered valves to reduce energy consumption and avoid excessive heat dissipation.

[0007] Furthermore, in one intelligent power distribution cabinet of this application, a second ventilation fan is also installed on the double doors. The second ventilation fan is used to assist in heat dissipation. In high-load operation scenarios (such as high temperatures in summer or full load of electrical equipment), the second ventilation fan can provide additional intake or exhaust power, avoiding the "airflow dead zone" that may occur with ventilation from only one side, and ensuring that heat is evenly distributed inside the cabinet.

[0008] Furthermore, in this application, an intelligent power distribution cabinet includes a louvered valve comprising a valve body frame, multiple parallel blades, and an operating mechanism. Each blade has an axially connected shaft, and the corresponding valve body frame has a pair of shaft holes. Both ends of the connecting shaft pass through these shaft holes, allowing the blades to rotate around the connecting shaft. The operating mechanism is installed on the outside of the valve body frame and is used to drive the blades to rotate synchronously, thereby opening or closing the louvered valve and adjusting its opening degree. By rotating the blades around the connecting shaft, continuous angle adjustment of the louvered valve is achieved from fully closed (blades vertically closed) to fully open (blades horizontally extended). The ventilation volume can be dynamically adjusted within the range of 0%-100%. The operating mechanism drives all blades to rotate synchronously, ensuring consistent blade angles and avoiding uneven ventilation or jamming caused by asynchronous blade movements, thus achieving linear and precise control of the ventilation volume.

[0009] Furthermore, in one intelligent power distribution cabinet of this application, the operating mechanism includes a motor and a connector, which are connected to the connecting shaft of the blades via a pair of connecting rods. The motor is mounted on the cabinet via the connector, and its output end drives the blades to rotate synchronously. The forward and reverse rotation or speed adjustment of the motor can be directly controlled by a controller to achieve automated adjustment of the blade opening.

[0010] Furthermore, in one intelligent power distribution cabinet of this application, a set of electrical mounting racks is also provided inside the cabinet. These electrical mounting racks are arranged horizontally and are used to install electrical equipment. The horizontally arranged electrical mounting racks inside the cabinet provide a horizontal mounting surface for electrical equipment such as circuit breakers, contactors, and relays.

[0011] Furthermore, in one intelligent power distribution cabinet of this application, an inspection door is also provided on the opposite side of the double doors. The inspection door facilitates the inspection and maintenance of electrical equipment on the electrical mounting rack. The double doors are located on the front of the cabinet and are used for daily operations (such as closing the switch and setting parameters); the inspection door is located on the opposite side of the double doors, directly corresponding to the back of the electrical mounting rack, forming a two-way access structure of "front operation + rear maintenance".

[0012] Furthermore, in one intelligent power distribution cabinet of this application, a lifting ring is also installed at the top of the cabinet body for hoisting the cabinet body.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] 1. The intelligent power distribution cabinet described in this utility model monitors the internal temperature of the cabinet in real time through a temperature sensor. The controller dynamically adjusts the speed of the first ventilation fan and the opening status or degree of the louver valve according to the temperature signal, thereby achieving precise and constant temperature control inside the power distribution cabinet. It can quickly dissipate heat when the temperature rises and reduce energy consumption when the temperature drops, avoiding the energy waste or insufficient heat dissipation caused by fixed heat dissipation structures due to fixed wind speed, and improving the stability and reliability of the power distribution cabinet operation.

[0028] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 1-3 The intelligent power distribution cabinet shown includes a cabinet body 1, double doors 2, a controller 3, a ventilation component 4, a temperature sensor 5, a second ventilation fan 21, an electrical mounting bracket 6, an inspection door 7, and a lifting ring 8.

[0031] Cabinet 1 is the main structure, with four lifting rings 8 installed at the top for hoisting and transportation. Temperature sensors 5 are fixed to the inner wall of cabinet 1, and are connected to controller 3 installed on the upper side of cabinet 1 to monitor the temperature inside the cabinet in real time and transmit the data to controller 3.

[0032] The ventilation assembly 4 includes a pair of louvered valves 41 installed on both sides of the cabinet 1 and a first ventilation fan 42. The louvered valve 41 consists of a valve body frame 411, multiple parallel blades 412, and an operating mechanism 413. Each blade 412 has an axially connected shaft 4121, with a pair of shaft holes 4111 corresponding to the valve body frame 411. Both ends of the connecting shaft 4121 pass through the shaft holes 4111, allowing the blades 412 to rotate around the connecting shaft 4121. The operating mechanism 413 is installed on the outside of the valve body frame 411 and includes a motor 4131, a connector 4132, and a pair of connecting rods 4133. The motor 4131 is fixed to the cabinet 1 via the connector 4132, and its output end is connected to the connecting shaft 4121 of the blades 412 via the connecting rods 4133, driving the blades 412 to rotate synchronously, thereby opening, closing, and adjusting the opening degree of the louvered valve 41. The first ventilation fan 42 is set up in correspondence with the louver valve 41. The speed is adjusted by the controller 3, and the ventilation volume in the cabinet is dynamically controlled in conjunction with the opening change of the louver valve 41.

[0033] The double doors 2 are installed on the front of the cabinet 1, and a second ventilation fan 21 is installed on them to assist in heat dissipation under high load conditions and avoid airflow dead zones inside the cabinet. On the opposite side of the double doors 2 (the back of the cabinet 1), there is an access door 7, which provides direct access to the electrical mounting rack 6 horizontally arranged inside the cabinet 1. This facilitates the inspection and maintenance of electrical equipment such as circuit breakers and contactors installed on the electrical mounting rack 6, forming a two-way access structure of "front operation + rear maintenance".

[0034] Working principle: Temperature sensor 5 monitors the cabinet temperature in real time and feeds it back to controller 3. Controller 3 dynamically adjusts the speed of the first ventilation fan 42 and the opening of the louver valve 41 based on the temperature signal. When the temperature rises, the speed of the first ventilation fan 42 is increased and the opening of the louver valve 41 is widened to accelerate air circulation and heat dissipation; when the temperature drops, the speed of the first ventilation fan 42 is reduced and the opening of the louver valve 41 is decreased to reduce energy consumption. In high-load scenarios such as high temperatures in summer or full load of electrical equipment, controller 3 starts the second ventilation fan 21 on the double doors 2 to provide additional ventilation power, ensuring that heat is evenly distributed inside the cabinet and achieving precise temperature control.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
