Abstract
Description
Technical Field
[0001] The utility model relates to the field of temperature monitoring of power distribution equipment, and in particular to a temperature monitoring device for power distribution equipment based on the Internet of Things. Background Art
[0002] The Internet of Things originated in the field of media and is the third revolution in the information technology industry. The Internet of Things refers to connecting any object to the network through information sensing devices according to agreed protocols, and objects exchange and communicate information through information transmission media to achieve intelligent identification, positioning, tracking, supervision and other functions.
[0003] Distribution equipment is a general term for high-voltage distribution cabinets, generators, transformers, power lines, circuit breakers, low-voltage switch cabinets, distribution boards, switch boxes, control boxes and other equipment in the power system. Generally, the air temperature around the switch equipment in the high-voltage distribution room is required not to exceed 40°C, and the average value measured within 24 hours shall not exceed 35°C.
[0004] The existing temperature monitoring equipment for power distribution equipment has the following disadvantages:
[0005] In areas with lower latitudes, due to lower air pressure and continuous high temperatures in summer, electrical equipment continues to dissipate heat, and the temperature inside the distribution box is relatively higher. In existing Internet of Things distribution equipment, fans are installed inside the distribution box to ventilate and dissipate heat. However, the heat dissipation capacity is poor and cannot adapt to areas with higher temperatures.
[0006] In high altitude areas or desert areas, due to high air pressure, thin air, and sand specific heat capacity ( 0.92×10^3J / (kg·℃ ) is small, resulting in a large temperature difference between day and night. During the day, the solar radiation is strong and the temperature rises quickly, while at night, the heat gathered during the day is quickly dissipated and the temperature is low. In northern regions or high-latitude areas, the temperature is low in winter, and the low temperature will also affect the normal operation of electronic components. At night, the temperature drops sharply and may reach minus 20 degrees Celsius to minus 40 degrees Celsius. The existing distribution equipment temperature monitoring equipment is only equipped with a heat dissipation structure. In an extremely cold environment, it is necessary to increase the temperature inside the distribution box, otherwise the electronic equipment may stop working due to the extremely low temperature, causing serious consequences.
[0007] Existing temperature detection equipment is to install a temperature sensor inside the distribution box to detect the temperature inside the box. When an abnormality is detected, an alarm is issued. After receiving the alarm, the staff will go to deal with it. When the equipment is set far away, it may cause a fire due to the failure to arrive in time to deal with it, which may cause danger or damage electronic components. Utility Model Content
[0008] 1. Technical issues to be resolved
[0009] In view of the shortcomings of the prior art, the utility model provides a temperature monitoring device for power distribution equipment based on the Internet of Things, which solves the problems that the existing power distribution equipment has poor heat dissipation effect, lacks temperature regulation function, and when the heat dissipation equipment is damaged or operates abnormally, the temperature inside the distribution box continues to rise, which may cause a fire.
[0010] (II) Technical solution
[0011] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0012] A temperature monitoring device for power distribution equipment based on the Internet of Things, comprising a power distribution box, wherein a temperature monitoring component, a temperature regulating component and a temperature device controller are arranged inside the power distribution box, wherein the temperature monitoring component comprises
[0013] A first temperature sensor, which is located inside the power distribution box;
[0014] A signal receiving module, whose input end is electrically connected to the output end of the first temperature sensor;
[0015] The input end of the signal output module is electrically connected to the output end of the signal receiving module, and the output end of the signal output module is electrically connected to the temperature device controller. The output end of the temperature relay is electrically connected to the temperature device controller, the temperature monitoring component, the temperature adjustment component and the line controller.
[0016] Optionally, a second temperature sensor is provided outside the power distribution box, and an output end of the second temperature sensor is electrically connected to a temperature device controller;
[0017] Optionally, the temperature regulating component includes a refrigerator, and the input end is electrically connected to a temperature device controller;
[0018] Optionally, a heat dissipation grille matching the heat dissipation port of the refrigerator is provided on the side wall of the power distribution box;

[0020] Optionally, the temperature device controller is externally provided with a display screen, adjustment buttons and indicator lights;
[0021] Optionally, the adjustment button, which is used to adjust the set temperature value, is of button type or knob type.
[0022] (III) Beneficial effects
[0023] Compared with the prior art, the utility model provides a temperature monitoring device for power distribution equipment based on the Internet of Things, which has the following beneficial effects:
[0024] The utility model monitors the temperature inside the power distribution box in real time by arranging a first temperature sensor inside the power distribution box, and monitors the external environment in real time by arranging a second temperature sensor outside the power distribution box;
[0025] By setting a signal receiving module and a signal transmission module inside the distribution box, the temperature monitored by the temperature sensor is transmitted to the temperature device controller, and then the specific value and working status are displayed on the display screen set outside the temperature device controller, so that the staff can intuitively observe the temperature inside the distribution box and the external environment;
[0026] By installing a refrigerator, the inside of the distribution box can be quickly and continuously cooled in low-latitude areas with higher temperatures, so as to ensure that the service life of the electronic components inside the distribution box will not be reduced due to poor heat dissipation;
[0027] By installing an electric heater inside the distribution box, the temperature inside the distribution box is raised to keep it within the temperature range where the electronic components can work normally, which solves the problem that the electronic components cannot work normally at extremely low temperatures at night in high latitudes and high altitudes with large temperature differences, and extremely low temperatures even during the day on cloudy days or rainy and snowy weather;
[0028] By setting a temperature relay inside the distribution box, when the temperature inside the distribution box abnormally rises to the set temperature, the electrical components inside the distribution box are disconnected and stopped working, thus solving the problem of the internal temperature of the distribution box continuing to rise to the ignition point due to abnormal operation of the refrigerator, which may cause a fire.

DETAILED DESCRIPTION
[0034] The following will be combined with the attached embodiment of the present utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0035] Example:
[0036] See also Figures 1 to 4 , the embodiment of the utility model provides a technical solution:
[0037] like Figure 1 As shown, a temperature monitoring device for power distribution equipment based on the Internet of Things includes a power distribution box 1, in which a temperature monitoring component 2, a temperature adjustment component 3, a temperature device controller 4 and a cover 6 are arranged;
[0038] Specifically, the temperature monitoring assembly 2 includes a first temperature sensor 20, which is located inside the power distribution box 1, and a second temperature sensor 21, which is located outside the power distribution box 1;
[0039] The first temperature sensor 20 located inside the distribution box 1 monitors the temperature inside the distribution box 1 in real time, and the second temperature sensor 21 located outside the distribution box 1 detects the external ambient temperature in real time. The temperature sensor can be a thermocouple temperature sensor.
[0040] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. According to the sensor material and electronic component characteristics, it is divided into two categories: thermal resistors and thermocouples. Thermocouples are the most commonly used temperature sensors in temperature measurement. Their main advantages are wide temperature range and adaptability to various atmospheric environments. They are also strong, low-priced, and do not require power supply. Therefore, it is recommended to use thermocouple temperature sensors.
[0041] A signal receiving module 22, whose input end is electrically connected to the output ends of the first temperature sensor 20 and the second temperature sensor 21; a signal output module 23, whose input end is electrically connected to the output end of the signal receiving module 22, and whose output end is electrically connected to the temperature device controller 4;
[0042] Specifically, the temperature adjustment component 3 includes a refrigerator 31 and an electric heater 32, and the input ends of the refrigerator 31 and the electric heater 32 are electrically connected to the temperature device controller 4;
[0043] Furthermore, a heat dissipation grille 311 matching the heat dissipation opening of the refrigerator 31 is provided on the side wall of the power distribution box 1, and the heat dissipation opening of the refrigerator 31 faces the heat dissipation grille 311;
[0044] The normal operating temperature range of the distribution equipment is -5 degrees Celsius to 40 degrees Celsius. Generally, the temperature inside the distribution box 1 should be maintained at around 22 degrees Celsius, and the set value of the temperature adjustment device is 18-25 degrees Celsius. When the first temperature sensor 20 detects that the temperature inside the distribution box 1 has reached the set temperature upper limit of 25, or the second temperature sensor 21 detects that the external ambient temperature has reached the set temperature upper limit of 10-35, the temperature device controller starts the refrigerator 31 to cool down the inside of the distribution box 1; when the first temperature sensor 20 detects that the temperature of the distribution box has reached the lower limit of the set value, or the second temperature sensor 21 detects that the external ambient temperature is lower than the set value, the temperature device controller 4 starts the electric heater 32 to heat the inside of the distribution box 1. The temperature device controller 4 controls the refrigerator 31 and the electric heater 42 to adjust the temperature inside the distribution box 1 so that it can be stabilized within the set temperature range, which can extend the service life of the electrical components in the distribution box 1.
[0045] Specifically, a temperature relay 5 is also provided inside the distribution box 1, and its output end is electrically connected to the temperature device controller 4, the temperature monitoring component 2, the temperature adjustment component 3 and the line controller 6 inside the distribution box 1. When the refrigeration of the refrigerator 31 is abnormal, the temperature inside the distribution box continues to rise and reaches the set temperature of 55 degrees Celsius, the temperature sensor inside the temperature relay 5 will send an electrical signal, and this electrical signal will be amplified by the amplifier and then transmitted to the control circuit. The temperature relay 5 is started and all electrical components inside the distribution box 1 are turned off, so that all electronic components stop working, so as to avoid the temperature inside the distribution box 1 from continuing to rise. When the ambient temperature reaches 60 degrees Celsius, the electronic components may catch fire, so as to avoid the temperature inside the distribution box 1 from reaching the ignition point and causing a fire.
[0046] Specifically, the temperature device controller 4 is externally provided with a display screen 40, an adjustment button 41 and an indicator light 42. The display screen 40 can display the internal temperature of the distribution box 1, the set temperature value of the ambient temperature, the working status of the temperature monitoring component 2 and the temperature adjustment component 3 in real time. The adjustment button 41 adjusts the set temperature value. The adjustment button can be a button type or a knob type. The indicator light 42 displays the working status of each component.
[0047] The temperature relay 5 is a relay that operates when the external temperature reaches a given value. It is a contact induction sealed temperature relay with the characteristics of small size, light weight, high temperature control accuracy, etc. It is highly versatile. It is used for temperature control and overheat protection of monitoring camera equipment, motors, electrical equipment and other industries. The temperature relay operates due to the increase in ambient temperature or the temperature rise caused by the heat generated by the current passing through it. Since the on-resistance of the relay is very small, the temperature rise caused by the thermal effect of the current is also very small, which can be ignored compared with the ambient temperature rise. Therefore, the detection of the operating temperature and recovery temperature of the temperature relay is generally achieved by controlling the change in ambient temperature.
[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
