[0004] The purpose of the utility model is to provide a harmonic filtering distribution cabinet that can monitor whether the cabinet body leaks electricity in real time, can adapt to a humid working environment, and has strong practicality.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A harmonic filtering distribution cabinet includes a cabinet body. A harmonic filter is arranged at the top end inside the cabinet body, and a dehumidifying cooler is arranged at the bottom end inside the cabinet body. An insulating plate is fixedly installed on the side surface of the cabinet body, and an electric box is fixedly installed on the outer surface of the insulating plate. An insulating seat is fixedly installed on the upper end surface of the electric box. An installation hole is arranged on the side surface of the insulating seat, and a conductive rod is snap-fitted inside the installation hole. One end of the conductive rod abuts against the side surface of the cabinet body. A control relay is fixedly installed on the inner end surface of the electric box. One end of the conductive rod is electrically connected to the control end of the control relay. A buzzer is fixedly installed on the upper end surface of the electric box, and the buzzer is electrically connected to the control relay.

[0007] By adopting the above technical solutions, harmonic waves can be effectively eliminated, and at the same time, it can monitor whether the cabinet body leaks electricity in real time. Once leakage occurs, an alarm sound can be emitted in time.

[0008] Further, the dehumidifying cooler includes a housing. A plurality of through grooves are arranged on the outer surface of one side of the housing. A plurality of installation holes are arranged at one side position on the upper surface of the housing, and a fan is installed inside each installation hole. A refrigeration seat is arranged at the middle position inside the housing.

[0009] By adopting the above technical solutions, the air inside the cabinet body can circulate and flow.

[0010] Further, a plurality of mounting grooves are provided on the lower surface of the refrigeration seat, and a semiconductor refrigeration plate is installed inside each mounting groove, and a plurality of air flow through grooves are provided on the side surface of the refrigeration seat.

[0011] By adopting the above technical solution, the refrigeration seat can be effectively cooled, ensuring the stable progress of cooling and dehumidification.

[0012] Further, a drain pipe is fixedly connected to the lower surface of the housing, and the water outlet end of the drain pipe is placed outside the cabinet body.

[0013] By adopting the above technical solution, the cooling water can be effectively discharged.

[0014] Further, a support beam is fixedly connected to the inner wall of the cabinet body, and an inner mounting plate is fixedly installed on the outer surface of the support beam, and electrical components are fixedly installed on the outer surface of the inner mounting plate.

[0015] By adopting the above technical solution, it is convenient to install the remaining electrical components.

[0016] Further, a main switch is fixedly installed on the inner end face of the electric box.

[0017] By adopting the above technical solution, the total circuit can be conveniently controlled.

[0018] In summary, the beneficial technical effects of the present utility model are as follows:

[0019] 1. By arranging a harmonic filter inside the cabinet body of the present utility model, the resonant waves in the power supply circuit can be effectively filtered. At the same time, the conductive rod arranged on the insulating seat can monitor whether the cabinet body is leaking electricity in real time. Once the cabinet body leaks electricity, the current on the cabinet body is conducted to the control end of the control relay through the conductive rod, and the control relay closes the working circuit of the buzzer, and the buzzer emits an alarm sound to remind the staff that the power distribution cabinet is leaking electricity and should not be touched. Since an insulating plate is arranged between the electric box and the cabinet body, the electric energy on the cabinet body can be effectively prevented from being conducted to the electric box. At this time, the electric box can be opened and the main switch can be cut off, and the functionality and safety of the entire power distribution cabinet are effectively improved;

[0020] 2. When the present utility model is working, the fan can be started, and the rotation of the fan enables the air inside the cabinet body to circulate through the inside of the dehumidification cooler. Since a refrigeration seat is arranged at the middle position inside the housing, when the air circulates through the inside of the dehumidification cooler, it needs to pass through the air guide through grooves inside the refrigeration seat. During this process, the semiconductor refrigeration plate can effectively reduce the temperature of the refrigeration seat, and then can effectively cool the air passing through the inside of the refrigeration seat. At this time, the generated cooling water is collected at the bottom end inside the housing and finally discharged from the drain pipe, enabling the power distribution cabinet to better adapt to the humid environment and effectively improving the working stability.

Among them, by providing a harmonic filter 2 inside the cabinet body 1, the resonance waves in the power supply circuit can be effectively filtered. At the same time, the conductive rod 7 provided on the insulating seat 6 can monitor in real time whether the cabinet body 1 is leaking electricity. Once the cabinet body 1 leaks electricity, the current on the cabinet body 1 is conducted through the conductive rod 7 to the control end of the control relay 12, and the control relay 12 closes the working circuit of the buzzer 5, and the buzzer 5 emits an alarm sound to remind the staff that the power distribution cabinet is leaking electricity and should not be touched. Since an insulating plate 4 is provided between the electrical box 3 and the cabinet body 1, the electric energy on the cabinet body 1 can be effectively prevented from being conducted to the electrical box 3. At this time, the electrical box 3 can be opened and the main switch 13 can be cut off, and the functionality and safety of the entire power distribution cabinet are effectively improved.

[0027] Refer to Figure 1 、 Figure 3, the dehumidifying cooler 9 includes a housing 10. A plurality of through grooves are provided on the outer surface of one side of the housing 10. A plurality of mounting holes are provided at one side position of the upper surface of the housing 10, and a fan 11 is installed inside each mounting hole. A refrigeration seat 14 is provided at the middle position inside the housing 10. A plurality of mounting grooves are provided on the lower surface of the refrigeration seat 14, and a semiconductor refrigeration plate 15 is installed inside each mounting groove. A plurality of air flow through grooves are provided on the side surface of the refrigeration seat 14. A drain pipe 16 is fixedly connected to the lower surface of the housing 10, and the water outlet end of the drain pipe 16 is placed outside the cabinet 1. During operation, the fan 11 can be started. The rotation of the fan 11 enables the air inside the cabinet 1 to circulate through the inside of the dehumidifying cooler 9. Since the refrigeration seat 14 is provided at the middle position inside the housing 10, when the air circulates through the inside of the dehumidifying cooler 9, it needs to pass through the air guide through grooves inside the refrigeration seat 14. During this process, the semiconductor refrigeration plate 15 can effectively reduce the temperature of the refrigeration seat 14, and thus can effectively cool the air passing through the inside of the refrigeration seat 14. At this time, the generated cooling water gathers at the bottom end inside the housing 10 and finally drains out from the drain pipe 16, enabling the power distribution cabinet to better adapt to a humid environment and effectively improving the working stability.

[0029] Working principle: When in use, first install the device at the designated position, and then install the required electrical components inside the inner mounting plate 8. At this time, it can work. During operation, since the harmonic filter 2 is provided inside the cabinet body 1, the resonant waves in the power supply circuit can be effectively filtered. At the same time, the conductive rod 7 provided on the insulating seat 6 can monitor in real time whether the cabinet body 1 is leaking electricity. Once the cabinet body 1 leaks electricity, the current on the cabinet body 1 is conducted to the control end of the control relay 12 through the conductive rod 7, and the control relay 12 closes the working circuit of the buzzer 5, and the buzzer 5 emits an alarm sound to remind the staff that the power distribution cabinet is leaking electricity and should not be touched. Since the insulating plate 4 is provided between the electrical box 3 and the cabinet body 1, the electric energy on the cabinet body 1 can be effectively prevented from being conducted to the electrical box 3. At this time, the electrical box 3 can be opened and the main switch 13 can be cut off. When the power distribution cabinet is working, the fan 11 is started, and the rotation of the fan 11 enables the air inside the cabinet body 1 to circulate through the inside of the dehumidification cooler 9. Since the refrigeration seat 14 is provided at the middle position inside the housing 10, when the air circulates through the inside of the dehumidification cooler 9, it needs to pass through the air guide groove inside the refrigeration seat 14. During this process, the semiconductor refrigeration plate 15 can effectively reduce the temperature of the refrigeration seat 14, and then can effectively cool the air passing through the inside of the refrigeration seat 14. At this time, the generated cooling water gathers at the bottom end inside the housing 10 and finally drains out from the drain pipe 16.
