Technical Field

The utility model relates to the field of switch control cabinets, in particular to a combined high and low voltage switch control cabinet.

Background Art

High and low voltage switch control cabinet is a device used to control switchgear in power systems, usually used in power distribution systems. Its basic working principle is to switch the switchgear by controlling the electromagnetic device. The high and low voltage switch control cabinet can also monitor parameters such as current and voltage to protect electrical equipment from overload, short circuit and other faults. Through precise control and protection functions, the high and low voltage switch control cabinet can ensure the stable and safe operation of the power system.

Through research and analysis, it is found that traditional high and low voltage switch control cabinets have certain limitations in dehumidification and cooling, which may cause performance degradation or even damage of electrical equipment when operating in high temperature and high humidity environments. Due to the accumulation of heat generated by long-term operation, it is difficult to effectively remove it in a timely manner by relying solely on traditional ventilation and heat dissipation methods, which can easily affect the safety and stability of equipment use. In addition, electrical equipment in a high humidity environment is easily affected by moisture, which may cause safety hazards such as short circuits and leakage. Therefore, more effective dehumidification and cooling measures are needed to improve the reliability and performance of the equipment.

Example:

Referring to Figures 1-7, a combined high and low voltage switch control cabinet includes: a shell 1, a combined frame 2 is installed and fixed on the inner side of the shell 1, ventilation grilles 3 are installed and fixed on both sides symmetrically of the bottom of the shell 1, an exhaust fan 5, a temperature and humidity sensor 6, a central control module 7, and a heat sink 8 are installed and fixed on the top of the shell 1 in sequence, the heat sink 8 is installed and fixed in the through groove on the top of the shell 1, and the central control module 7 is respectively connected to the exhaust fan 5, the temperature and humidity sensor 6, and the heat sink 8.

One side of the housing 1 is rotatably connected to a cabinet door 11 , and the side of the housing 1 away from the cabinet door 11 is rotatably connected to a cabinet door 2 12 .

The assembly frame 2 is provided with two U-shaped bars 21 parallel to each other in the vertical direction. A plurality of through holes 22 are evenly distributed on the U-shaped bars 21 . A plurality of mounting plates 23 are fixedly mounted between the two U-shaped bars 21 .

The mounting plates 23 are fixedly connected to the through holes 22 distributed on the U-shaped bar 21 by means of bolts. The plurality of mounting plates 23 are respectively used for mounting and fixing the transformer and the control switch.

Two symmetrical L-shaped blocks 41 are fixedly mounted on one side surface of the U-shaped bar 21. The two L-shaped blocks 41 and the inner wall of the outer shell 1 together form a mounting groove. A desiccant 4 is inserted into the mounting groove. The desiccant 4 is adapted to the size of the air grille 3 and is located on the inner side of the air grille 3.

The heat dissipation device 8 includes a radiator 81, a semi-conductive cooling fin 82, and a heat absorbing plate 83 which are fixedly connected in sequence from top to bottom. The radiator 81 is located on the upper side of the shell 1, the semi-conductive cooling fin 82 is fixed in a through groove on the shell 1, and the heat absorbing plate 83 is located inside the shell 1.

Lifting rings 9 are fixedly installed at the four top corners of the housing 1; as shown in FIG1 , the four lifting rings 9 at the top of the housing 1 mainly serve to facilitate operators to lift the entire device in the vertical direction.

Working principle: In the utility model, a plurality of display instruments are installed on the surface of the cabinet door 11 on the front of the housing 1, which is convenient for the operator to set and read the real-time data of the electrical appliances in the housing 1. After the cabinet door 2 12 on the back of the housing 1 is opened, it is convenient for the operator to perform corresponding maintenance on the electrical equipment in the housing 1. As shown in FIG4, the operator can set the number and spacing of the plurality of mounting plates 23 between the two U-shaped strips 21 as needed according to the use requirements to meet the installation combination requirements under different power distribution requirements. As shown in FIG7, the operator can replace the desiccant 4 in a timely manner when it is close to the saturated state of moisture absorption to meet a better dehumidification effect;

When the high-voltage equipment, transformer, and low-voltage equipment installed on the combination frame 2 in the shell 1 are put into operation as a whole, a large amount of heat will be generated. When the temperature and humidity sensor 6 detects that the temperature and humidity in the shell 1 increase and do not exceed the set threshold, it will transmit the signal to the central control module 7, and the central control module 7 will send a control signal to the exhaust fan 5. As shown in Figure 3, after the exhaust fan 5 is started, the external air enters the bottom of the shell 1 through the air grille 3, and the desiccant 4 has a loose porous structure, which can ensure gas circulation while absorbing moisture. With the continuous start-up of the exhaust fan 5, the external gas envelops the high-temperature gas in the shell 1 and is discharged from the bottom of the exhaust fan 5 to the outside to achieve the purpose of cooling. It should be noted that the model of the temperature and humidity sensor 6 in the utility model can be D HT11, but not limited to this model; when the temperature and humidity sensor 6 detects that the temperature inside the shell 1 rises and exceeds the set threshold, it will transmit a signal to the central control module 7, and the central control module 7 will send a control signal to the heat dissipation device 8, as shown in Figure 5, the cooling surface of the semiconductor refrigeration plate 82 faces downward and contacts with the heat absorption plate 83, and the heat dissipation surface of the heat absorption plate 83 faces upward and is connected to the radiator 81. After power is turned on, the cooling surface of the semiconductor refrigeration plate 82 begins to cool so that the temperature of the surface of the heat absorption plate 83 drops rapidly after absorbing heat, and the radiator 81 is started so that the heat dissipated from the upper surface of the semiconductor refrigeration plate 82 is discharged to the outside of the shell 1, thereby improving the heat dissipation effect in the shell 1. The heat dissipation process is automatic until the temperature and humidity sensor 6 detects that the temperature and humidity in the shell 1 are at normal values.
