Technical Field
[0001] This utility model relates to the field of high and low voltage switchgear, and in particular to a high and low voltage switchgear with temperature control function. Background Technology
[0002] High and low voltage switchgear is a complete set of electrical equipment used in power systems for power distribution, control and circuit protection. It can receive, protect and monitor power. It consists of a variety of electrical components assembled in a closed or semi-closed metal cabinet to form a complete power distribution device.
[0003] However, current high and low voltage switchgear cannot adjust the heat dissipation intensity according to the internal temperature of the switchgear, which will lead to problems such as insufficient heat dissipation or excessive energy consumption. In addition, the use of blowers to dissipate heat inside the switchgear is usually ineffective and difficult to cool it down. Therefore, we propose a high and low voltage switchgear with temperature control function to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high- and low-voltage switchgear with temperature control function includes a switchgear body. A temperature sensor is fixedly installed on the inner top wall of the switchgear body. A first tube is fixedly connected to the right side of the switchgear body. A semiconductor cooling chip is fixedly installed on the inner wall of the first tube. A blower is fixedly installed on the inner wall of the first tube. A first exhaust fan is fixedly installed on the inner wall of the first tube. An air guide shell is fixedly installed on the inner side wall of the switchgear body. Multiple air guide ports are opened on the left side of the air guide shell. A second tube is fixedly connected to the left side of the switchgear body. A second exhaust fan is fixedly installed on the inner wall of the second tube.
[0007] In a further embodiment, a base is fixedly installed on the bottom surface of the switch cabinet, and two sets of mounting ports are provided on the upper surface of the base.
[0008] In a further embodiment, the front of the switch cabinet is hinged to a cabinet door, and a PLC control panel is fixedly installed on the front of the cabinet door.
[0009] In a further embodiment, a first protective net is fixedly connected to the inner wall of the first tube, and a second protective net is fixedly connected to the inner wall of the second tube.
[0010] In a further embodiment, the outer surface of the first tube is provided with a plurality of ventilation openings, and a dustproof net is fixedly connected to the inner wall of each ventilation opening.
[0011] In a further embodiment, an air guide plate is fixedly installed on the inner top wall of the air guide shell, and the air guide plate is located to the left of the blower.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This device, through the settings of temperature sensors and PLC control panel, can monitor the temperature inside the switch cabinet in real time and transmit the signal. At the same time, it can adjust the heat dissipation equipment according to the preset temperature threshold to avoid insufficient heat dissipation and excessive energy consumption caused by constant heat dissipation intensity. By using semiconductor cooling chips, blowers, first exhaust fans and second exhaust fans, and through the cooperation of air guide shells, air guide ramps and multiple air guide ports, it can generate cold air and deliver and guide the cold air to diffuse evenly into the interior of the switch cabinet to cool down the internal components.

[0022] Please see Figure 1-4In this utility model, a high and low voltage switchgear with temperature control function includes a switchgear body 1. A temperature sensor 2 is fixedly installed on the inner top wall of the switchgear body 1. A first tube 3 is fixedly connected to the right side of the switchgear body 1. A semiconductor cooling chip 4 is fixedly installed on the inner wall of the first tube 3. A blower 5 is fixedly installed on the inner wall of the first tube 3. A first exhaust fan 6 is fixedly installed on the inner wall of the first tube 3. An air guide shell 7 is fixedly installed on the left side of the air guide shell 7. Multiple air guide ports 8 are opened on the left side of the switchgear body 1. A second tube 9 is fixedly connected to the left side of the switchgear body 1. A second exhaust fan 10 is fixedly installed on the inner wall of the second tube 9. The temperature sensor 2 and PLC control panel 1 control the switchgear. The setting 3 allows for real-time monitoring of the internal temperature of switch cabinet 1 and transmission of the signal. Simultaneously, it adjusts the heat dissipation equipment based on a preset temperature threshold, avoiding insufficient heat dissipation and preventing excessive energy consumption caused by constant heat dissipation intensity. Utilizing the semiconductor cooling chip 4, blower 5, first exhaust fan 6, and second exhaust fan 10, along with the cooperation of air guide shell 7, air guide ramp 11, and multiple air guide ports 8, cool air is generated and evenly distributed into the interior of switch cabinet 1 to cool the internal components. At the same time, it removes heat from the hot surface of the semiconductor cooling chip 4 and extracts hot air from inside switch cabinet 1, forming good air circulation and enhancing the heat dissipation effect.
[0023] A base 14 is fixedly installed on the bottom surface of the switch cabinet 1. Two sets of mounting holes 15 are opened on the upper surface of the base 14. A cabinet door 12 is hinged to the front of the switch cabinet 1. A PLC control panel 13 is fixedly installed on the front of the cabinet door 12. A first protective net 16 is fixedly connected to the inner wall of the first through cylinder 3, and a second protective net 17 is fixedly connected to the inner wall of the second through cylinder 9. The base 14 and the two sets of mounting holes 15 can fix the switch cabinet 1 to prevent it from shifting or tipping over during use. The cabinet door 12 can protect the electrical components inside the switch cabinet 1. The PLC control panel 13 can regulate the temperature inside the switch cabinet 1 and display temperature and other information for easy monitoring by operators. The first protective net 16 and the second protective net 17 can block larger debris from the outside.
[0024] Multiple ventilation openings 18 are provided on the outer surface of the first tube 3. Each ventilation opening 18 has a dustproof net 19 fixedly connected to its inner wall. An air guide plate 11 is fixedly installed on the inner top wall of the air guide shell 7. The air guide plate 11 is located to the left of the blower 5. The multiple ventilation openings 18 and multiple dustproof nets 19 can provide an air channel for ventilation and heat dissipation inside the switch cabinet 1, while preventing dust and debris from entering the interior of the switch cabinet 1. The air guide plate 11 can guide and direct the blown airflow, so that the airflow can be distributed more evenly and effectively into the air guide shell 7.
[0025] The working principle of this utility model is as follows:
[0026] First, temperature sensor 2 monitors the temperature inside switch cabinet 1 in real time and transmits the temperature signal to PLC control panel 13. Simultaneously, PLC control panel 13 analyzes the signal according to a preset temperature threshold. When the temperature inside switch cabinet 1 exceeds the set threshold, PLC control panel 13 activates the thermoelectric cooler 4 for cooling and starts the blower 5 to blow the generated cold air into the air guide housing 7. The air guide plate 11 guides the cold air, which is then evenly diffused into the interior of switch cabinet 1 through multiple air vents 8. Next, the first exhaust fan 6 and the second exhaust fan 10 are activated. The first exhaust fan 6 removes the heat generated by the hot surface of the thermoelectric cooler 4, while the second exhaust fan 10 extracts the hot air inside switch cabinet 1 through the second duct 9, creating good air circulation and enhancing heat dissipation. This cools the internal components. When the temperature inside switch cabinet 1 drops below the set threshold, PLC control panel 13 reduces the power of the thermoelectric cooler 4, decreases the speed of the blower 5, the first exhaust fan 6, and the second exhaust fan 10, or even shuts down some equipment as needed to avoid excessive energy consumption.
