Technical Field
[0001] This utility model belongs to the field of power detection technology, specifically an outdoor power consumption detection module protection device. Background Technology
[0002] With the rapid development of society, people's electricity demand is gradually increasing. Along with the vigorous development of the power industry, the number of power plants and substations is also gradually increasing. Power consumption detection modules play a crucial role in the maintenance of power plants and substations. These modules can monitor the output and input of electricity at any time, ensuring the stability of the power grid voltage. However, power plants and substations have many outdoor devices. If power consumption detection modules are placed outdoors alone, they are easily damaged by rain and dust, leading to short circuits and burnout. Since power consumption detection modules are usually connected to high-voltage lines, they generate a large amount of heat during the detection process. Existing protection devices for power consumption detection modules only protect them, resulting in poor heat dissipation in summer and excessive cooling in winter, which can easily lead to measurement errors and other malfunctions. This can easily cause the modules to spontaneously combust, leading to larger accidents and increased losses. Therefore, it is necessary to design a protection device that can protect power consumption detection modules from wind, sand, and rain erosion, and can adjust heat dissipation and heating according to the external temperature to maintain a constant temperature. Utility Model Content
[0003] To address the above technical problems, this utility model provides a protection device that can protect the power consumption detection module from wind, sand, and rain erosion, and can heat and cool the module according to the external temperature to maintain a constant temperature. This solves the problems of poor heat dissipation at high temperatures, inaccurate detection due to excessive cooling of the power consumption detection module at low temperatures, and the vulnerability of the power consumption detection module to wind, sand, and rain erosion.
[0004] To solve the above technical problems, the technical solution of this utility model is as follows: an outdoor power consumption detection module protection device, including a protection box, a grid plate fixedly connected to the middle of the protection box, a heat exchanger arranged below the grid plate, the two sides of the heat exchanger fixedly connected to the side wall of the protection box, a condenser fixedly connected to the lower part of one side of the protection box, the heat exchanger being connected to the condenser through a condensing pipe, fans symmetrically fixedly connected to the bottom of the protection box, and air outlets opened on both sides of the top, a power consumption detection module fixedly connected to the grid plate, heaters arranged on both sides of the power consumption detection module, the heaters being fixedly connected to the inner side wall of the protection box, a temperature sensor fixedly connected to the rear wall of the inner side of the protection box, a door hinged to the front, a control box fixedly connected to the door, an emergency stop button provided on the control box, a cover fixedly connected to the top of the protection box, and a check valve installed in the air outlet.
[0005] Furthermore, the heat exchanger includes a heat exchange tube and heat sinks. The heat sinks are vertically fixedly connected to the heat exchange tube, and both ends of the heat exchange tube penetrate the side wall of the protective box and are fixedly connected to the condenser tube.
[0006] Furthermore, a filter screen is detachably connected to the input end of the fan.
[0007] Furthermore, the heater, fan, and condenser are all controlled by the control box, and the power consumption detection module is electrically connected to the emergency stop button.
[0008] Furthermore, the bottom of the protective box is fixedly connected with support legs.
[0009] This utility model has the following advantages compared with the prior art:
[0010] 1. This utility model, by setting up a protective box, fixes the power consumption detection module inside the protective box, which can prevent the power consumption detection module from being corroded by rain and sand, thus preventing damage. By setting a fan at the bottom of the protective box, a heat exchanger above the fan, and air outlets on both sides of the top of the protective box, the air can be cooled by the fan passing through the heat exchanger and then blown onto the power consumption detection module for cooling. The high-temperature air is blown out from the air outlets above to achieve the purpose of heat dissipation. By setting heaters on both sides of the power consumption detection module, the power consumption detection module can be heated when the air temperature is low, avoiding large temperature differences that could cause inaccurate power consumption detection or damage to the device.
[0011] 2. This utility model, by installing a check valve inside the air outlet and detachably connecting a filter screen at the fan input end, can prevent sand and soil from entering the protection box from the air outlet and fan and damaging the power consumption detection module. By setting an inclined cover on the top of the protection box, it can prevent rainwater from accumulating on the top of the protection box and causing corrosion to the box body. By electrically connecting the power consumption detection module to the emergency stop button, it can protect personnel from accidentally touching the power consumption detection module. When performing maintenance or inspection, the power can be cut off before opening the box door. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figures 1 to 3 The outdoor power consumption detection module protection device shown includes a protection box 1. For easy installation of the power consumption detection module 3, a grid plate 2 is fixedly connected to the center of the protection box 1. To better cool the power consumption detection module 3, a heat exchanger 4 is installed below the grid plate. The heat exchanger 4 is fixedly connected to the side walls of the protection box 1 on both sides. To ensure a low temperature inside the heat exchanger 4, a condenser 12 is fixedly connected to the lower part of one side of the protection box 1. The heat exchanger 4 is connected to the condenser 12 via a condenser pipe 6. To ensure ventilation inside the protection box 1 and reduce the temperature of the power consumption detection module 3, fans 7 are symmetrically fixedly connected to the bottom of the protection box 1, and air outlets 9 are opened on both sides of the top. When the temperature of the power consumption detection module 3 is high, air is blown in by the fans 7, cooled by the heat exchanger 4, and then blown onto the power consumption detection module 3, expelling the hot air from the air outlets 9 for heat exchange. To facilitate faster heat dissipation of the power consumption detection module 3, a grid plate 2 is fixedly connected to the grid plate 2. A power consumption detection module 3 is connected. To heat the power consumption detection module 3 when the temperature is low and avoid affecting the detection results, heaters 5 are installed on both sides of the power consumption detection module 3. The heaters are fixedly connected to the inner wall of the protection box 1. To monitor the temperature inside the protection box 1 at all times and keep it within a certain range to prevent the detection accuracy from being affected by temperature, a temperature sensor 11 is fixedly connected to the rear wall of the protection box 1. For convenient maintenance and inspection, a box door 14 is hinged to the front of the protection box 1. To improve the automation of the device, a control box 15 is fixedly connected to the box door 14. The temperature sensor 11 is electrically connected to the control box 15. To prevent maintenance personnel from opening the box door 14 at will and causing electric shock, an emergency stop button 16 is installed on the control box 15. To prevent rainwater from corroding the box body, a box cover 10 is fixedly connected to the top of the protection box 1. To prevent sand and dust from entering the protection box 1 from the air outlet 9, a check valve 13 is installed inside the air outlet 9.
[0018] It should be noted that the fan 7 in this utility model is existing technology and will not be described in detail here.
[0019] In order to increase the heat exchange area of heat exchanger 4 and improve the cooling efficiency, heat exchanger 4 includes heat exchange tube 41 and heat sink 42. Heat sink 42 is vertically fixedly connected to heat exchange tube 41, and both ends of heat exchange tube 41 pass through the side wall of protective box 1 and are fixedly connected to condenser tube 12.
[0020] To prevent dust from being sucked in from the input end of the fan 7 during the blowing process, which could damage the power consumption detection module 3, a filter screen 8 is detachably connected to the input end of the fan 7 by bolts.
[0021] To improve the automation level of the device, the heater 5, fan 7, and condenser 12 are controlled by the control box 15. To protect maintenance personnel from electric shock, the power detection module 3 is electrically connected to the emergency stop button 16.
[0022] To facilitate air blowing by the fan 7 at the bottom of the protective box 1, a support leg 17 is fixedly connected to the bottom of the protective box 1.
[0023] The specific working process of this utility model is as follows:
[0024] The power consumption detection module 3 is installed inside the protection box 1. When the outside temperature is high, the power consumption detection module 3 operates continuously for a period of time, after which its temperature begins to rise rapidly. At this time, the temperature sensor 11 detects that the temperature inside the box has reached a certain value and transmits a signal to the control box 15. The control box 15 controls the fan 7 and the condenser 12 to start operating. The condenser 12 transfers the refrigerant to the heat exchange tube 41, causing the air temperature around the heat exchanger 4 to drop. The fan 7 blows the cold air around the heat exchanger 4 onto the power consumption detection module 3, cooling the power consumption detection module 3. Finally, the hot air around the power consumption detection module 3 is blown out of the protection box 1 from the upper air outlet 9. When the outside temperature is low, the power consumption detection module... 3. Low temperatures may affect the accuracy of the detection results. In this case, the temperature sensor 11 detects that the temperature has dropped to a certain value and sends a signal to the control box 15. The control box 15 controls the heater 5 to start heating the power detection module 3 until it reaches a constant temperature. When the dust on the filter screen 8 is full, it is removed and cleaned to avoid affecting the airflow of the fan 7. When it is necessary to inspect and repair the inside of the protection box 1, the power inside the protection box 1 should be cut off by the emergency stop button 16 before inspection and repair. Protecting the power detection module 3 according to the above steps can improve the service life of the power detection module 3 and improve the detection accuracy of the power detection module 3 under any circumstances.
