Description

Technical Field

[0001] The present invention relates to the technical field of high and low voltage power distribution cabinets, and in particular to a multifunctional integrated intelligent high and low voltage power distribution cabinet and a use method thereof. Background Art

[0002] With the continuous growth of the global economy, especially the rapid development of industries, commerce and infrastructure construction, the demand for electricity is increasing. As key equipment for power distribution and control, high and low voltage distribution cabinets are the basis for ensuring the power supply of various power consumption sites, and the market demand is also expanding. For example, in commercial centers, industrial parks, large data centers and other places in the city, a large number of power equipment and power loads require reliable high and low voltage distribution cabinets for power distribution and management.

[0003] High and low voltage distribution cabinets need to adapt to the access of new energy and the development of distributed energy, and realize the effective integration and distribution of different energy forms; the current network security protection measures of the equipment are not in place, and may be subject to security threats such as hacker attacks and data leakage, affecting the safe operation of the power system and the privacy of users; the vast majority of high-voltage cabinets on the market currently do not have special test holes or test components, which makes the test operation difficult and cannot effectively guarantee the safety of operators. The internal structure of the distribution cabinet is complex and there are many electrical components. When performing equipment maintenance and repair, professional technicians and special tools are required. In addition, some old distribution cabinets may lack complete identification and records, which increases the difficulty of maintenance and management.

[0004] Therefore, it is very necessary for the present application to propose a multifunctional integrated intelligent high and low voltage distribution cabinet and a method of use to solve the problems in the background.

[0005] 1. Patent document CN113067255B discloses an intelligent monitoring type high and low voltage distribution cabinet and its monitoring method. The above patent solves the problem that the inner cavity of the current high and low voltage distribution cabinets are all rectangular. In order to ensure the heat dissipation of multiple chambers such as the high-voltage chamber and the low-voltage chamber in the high and low voltage distribution cabinet, multiple cooling fans or cooling pipes are required to be provided at the rear end for heat dissipation. Multiple cooling devices are turned on at the same time to dissipate heat together, which requires more energy consumption. However, the above patent cannot realize the detection of whether the lines in the distribution cabinet are energized and the energized voltage level without opening the cabinet.

[0006] 2. Patent document CN116960774B discloses an intelligent, safe and insulated high and low voltage distribution cabinet. The above patent realizes that when in use, the slider of the installation component slides up and down in the shell, and then the position of the distribution equipment is installed and fixed by the limit block, and finally all the connecting wires are gathered together through the wire collection sleeve for easy fixation and storage, and then the heat dissipation component is used to dissipate the heat of the entire distribution cabinet. Specifically, rainwater is collected through the sump on rainy days, and then introduced into the shell through the water pipe, and the heat is volatilized by contacting with the heat sink, and then the air in the shell is driven to circulate through the cooling fan, so as to dissipate heat with the help of rainwater, making it more energy-saving to use. Finally, a moisture-proof component is arranged in the shell to detect the humidity in the shell, and the dehumidification is turned on after the humidity exceeds the preset value, so as to avoid circuit failure caused by too high humidity, so as to increase the service life of the distribution cabinet, but the above patent cannot prevent external interference signals and internal electromagnetic signals from leaking.

[0007] 3. Patent document CN117810826B discloses a high and low voltage intelligent distribution cabinet. The above patent realizes that when a fire hazard occurs, the fire source detection sensor performs timely detection, so that the micro gas rod is started under the signal command of the fire source detection sensor, and drives the force-bearing spring member and the pressing rod to retract, and then the central elastic abutment member drives the pressing insulation end to be retracted from the outside of the two distribution lines formed by the docking, so that the pressing connection of the two distribution lines formed by the docking is disconnected, reducing the ignition point, and preventing the subsequent continuous fire source from occurring inside the cabinet (21), causing damage to the internal components of the cabinet (21), while reducing the risk of explosion. However, the above patent cannot realize the function of authorized locking of the distribution cabinet.

[0008] 4. Patent document CN116826573B discloses an intelligent explosion-proof high and low voltage distribution cabinet. The above patent realizes the provision of a dividing plate one and a dividing plate two. When the external air enters the lower cavity through the air inlet, and then in the air flow channel formed by the dividing plate and the dividing plate one in the lower cavity, the electric heating plate installed on the dividing plate one heats and dries the air in the lower cavity, and then the air enters the upper cavity through the through hole two, and the refrigeration plate on the dividing plate two dries the hot air to avoid the temperature increase in the distribution cabinet affecting the heat dissipation. However, the above patent cannot achieve the free heat dissipation of the distribution cabinet to maintain a constant internal temperature.

[0009] In summary, the above patents cannot realize the functions of detecting whether the lines in the distribution cabinet are energized and the energized voltage level without opening the cabinet, preventing the leakage of external interference signals and internal electromagnetic signals, locking the distribution cabinet with authorization, and maintaining the internal constant temperature by the distribution cabinet's free heat dissipation, which leads to electric shock safety accidents caused by operators' misjudgment, electromagnetic signals interfering with each other in complex electrical situations, and dangers caused by unauthorized personnel opening the cabinet at will. The electrical components inside the high and low voltage distribution cabinets are concentrated, and the heat generated during operation is large and cannot be dissipated. To this end, the present application proposes a multifunctional integrated intelligent high and low voltage distribution cabinet and a method of use that can detect whether the lines in the distribution cabinet are energized and the voltage level of the energized lines without opening the cabinet, prevent the leakage of external interference signals and internal electromagnetic signals, authorize the locking of the distribution cabinet, and allow the distribution cabinet to dissipate heat freely to maintain a constant internal temperature.
