[0028] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] Please refer to Figure 1 、 Figure 2 、 Figure 3 And Figure 4 The utility model discloses an automatic temperature measurement power distribution cabinet, including the cabinet body 10 and the hinge in the cabinet body outside door 14. The vertical busbar row 33 and the multiple circuit breakers 13 located in the busbar row 33 both sides are installed in the cabinet body 10, and the conductive plug of circuit breaker 13 is inserted on the edge of busbar row 33. It also includes the temperature measurement module for detecting the temperature of busbar, and the temperature measurement module includes the temperature measurement strip 9 installed on the back of busbar, and the temperature measurement strip is high-precision thermistor. The control panel is installed on the cabinet body, and the temperature measurement strip is electrically connected with the control panel. In this way, the temperature measurement strip is installed behind the busbar, the temperature measurement strip is made of high-precision thermistor material, can directly contact the busbar, can accurately collect temperature signals and convert temperature signals into electrical signals and output to the control panel, the control panel receives signals and processes, sets the temperature setting value on the control panel, and sends an alarm signal when the setting value is exceeded, and the control panel alarm light is bright, prompting the temperature is too high.

[0030] Among them, the circuit breaker 13 is assembled in the cabinet body 10 through the mounting structure. The mounting structure includes the bracket 12 and the mounting plate 11 located behind the vertical busbar row 33 in the cabinet body 10 of the power distribution cabinet. The bracket 12 is installed on the back of the circuit breaker 13. The hole assembly 20 is provided on the mounting plate. The hole assembly is composed of the horizontally arranged slot 21 and the mounting hole 22. The bottom surface of the bracket 12 is provided with the hook head 121 inserted into the slot, and the tail end is provided with the through hole 122 communicated with the mounting hole. The locking screw is arranged in the through hole 122 and the mounting hole 22. Of course, the bracket 12 can be provided with multiple sizes to meet the installation requirements of circuit breakers of different sizes.

[0031] As Figure 3As shown, the end of slot 21 near the busbar has a tapered head with a gradually narrowing width. Additionally, a through hole 123 is provided at the rear of bracket 12. Auxiliary holes 23 are provided between slot 21 and mounting hole 22, corresponding to the through hole 123, to adjust the position of bracket 12. There are four auxiliary holes 23, spaced apart along the length of the mounting plate. During assembly, the tip of a flathead screwdriver is inserted through the through hole 123 into the auxiliary hole 23 biased towards the busbar. Then, using the auxiliary hole 23 as a fulcrum, the screwdriver is used to push the bracket to one side of the busbar, causing the circuit breaker to engage with the busbar. Because the end of the slot has a tapered head with a gradually narrowing width, the end of the bracket clamps the hook during engagement. When mounting hole 22 aligns with through hole 122, the end of the locking screw is passed through through hole 122 and tightened into mounting hole 22. Multiple auxiliary holes improve installation flexibility and precision. When removal is required, it can also be done quickly through auxiliary hole 23.

[0032] like Figure 2 As shown, in this embodiment, multiple sets of hole assemblies 20 are arranged along the height direction of the mounting plate. This structure allows multiple circuit breakers 13 to be installed in different positions. A vertical row of hole assemblies 15 is symmetrically arranged on both sides of the busbar on the mounting plate. Furthermore, a vertical row of hole assemblies 15 is also provided outside the outer side of one of the vertical rows of hole assemblies, allowing larger circuit breakers to be installed on the outer hole assemblies 15.

[0033] Combination Figure 5 and Figure 6 As shown, in this embodiment, an inner door 30 is installed inside the cabinet 10 in front of the mounting plate 11. The inner door 30 has a window 31 for easy operation of the circuit breaker 13. Recessed frame 32 extends inwardly around the perimeter of the window 31. A busbar cover 34, which encloses the busbar 33, is located inside the window 31. The busbar cover 34 has multiple ventilation holes. The inner door 30 consists of an upper door body 301 and a lower door body 302. During normal use, closing the inner door 30 provides protection, preventing injury to operators during maintenance and repair; it can be opened for convenient maintenance. The window also facilitates operation of the circuit breaker.

[0034] The ventilation base 102 is further included. The cabinet body 10 is installed on the ventilation base 102. The ventilation base 102 is in communication with the inside of the cabinet body 10. The first ventilation hole 103 is arranged on the ventilation base 102 and the lower part of the outer door 11. The second ventilation hole 104 is arranged on the upper door body 301 of the inner door 30 and the upper part of the outer door 14. After the busbar works for a period of time, the air temperature in the cabinet body rises due to heat. The hot air rises due to small density, is discharged through the second ventilation hole at the top of the cabinet body, and cold air is continuously supplemented into the cabinet body through the first ventilation hole at the bottom, so that the cabinet body forms a natural ventilation circulation, thereby achieving the purpose of heat dissipation.

[0035] In combination Figure 6 As shown in the cabinet body 10, the left and right sides are respectively installed with the side plates 15. A plurality of installation openings 151 are arranged on each side plate 15 from top to bottom. The installation plate 16 is detachably installed at each installation opening 151. Each installation plate 16 is fixed on the side plate 15 through a screw. Since the power distribution cabinet generally adopts a fully enclosed structure, the main purpose is to prevent the invasion of dust, moisture and other impurities from the outside, so as to ensure the safe and reliable operation of the electrical equipment. Therefore, during the manufacturing process of the power distribution cabinet, the holes for the power supply of the equipment are not pre-installed on the power distribution cabinet. Generally, before the power distribution cabinet is installed in the power distribution room, according to the actual needs, the holes with the number and size suitable for the power supply of the equipment are accurately opened on site. Then, the power distribution cabinet is installed in the power distribution room, and the power supply of the equipment is connected with the busbar in the power distribution cabinet through the circuit breaker. However, when the enterprise needs to add new equipment, there is no hole on the power distribution cabinet for the power line of the new equipment to pass through. If the power distribution cabinet is directly opened in the power distribution room to solve this problem, it may cause serious safety hazards. However, when the power line of the new equipment needs to be connected to the power distribution cabinet, the installation plate at the installation opening can be removed, then the installation plate 16 is moved to the outside of the power distribution room and a hole suitable for the power line of the equipment is opened, then the installation plate with the hole is installed back to the original position, and the power line of the new equipment is connected with the circuit breaker in the power distribution cabinet through the hole in the installation plate 16, which is very safe and convenient.

[0036] In combination Figure 7As shown, in the present embodiment, the mounting plate 16 comprises a plate body 161 and a lower edge connected to the lower edge of the plate body 161. The lower edge of the upper mounting plate 16 is pressed against the upper edge of the adjacent lower mounting plate 16. The lower edge comprises an inclined portion 162 connected to the lower edge of the plate body 161 and a vertical portion 163 connected to the lower edge of the inclined portion 162. A sealing rubber is attached to the inner side of the lower edge. Since the mounting plate is detachably mounted at the mounting opening, there will be a gap between the mounting plate 16 and the side plate 15. When it is humid and cold, because of the temperature difference between the inside and outside of the cabinet, water vapor in the air will attach to the surface of the cabinet to form water droplets. When the water droplets flow down the side plate, they may seep into the cabinet through the gap between the mounting plate 16 and the side plate 15, causing a safety hazard. With the structure of the mounting plate described above, when there are water droplets on the side plate, the water droplets directly drip onto the bottom surface along the plate body and the lower edge, preventing liquid from seeping into the cabinet. In addition, the upper edge of the uppermost mounting plate and the side plate can be sealed with a sealing rubber to prevent water droplets from seeping between the uppermost mounting plate and the side plate.

[0037] In summary, in the utility model, the temperature measuring strip is installed behind the busbar, the temperature measuring strip is a thermistor which can directly contact the busbar, can accurately collect temperature signals and convert the temperature signals into electrical signals to output to the control panel, the control panel receives the signals and processes them, and when the temperature exceeds the set value, an alarm signal is sent out, the alarm light is on, and the temperature is too high. When installing the circuit breaker, the bracket is installed on the back of the circuit breaker, the hook of the bracket is inserted into the slot, and the auxiliary hole is matched with the perforation to quickly install the bracket in place, so that the conductive plug of the circuit breaker is inserted on the busbar, and finally fixed by the locking screw. The structure is simple and convenient to use. An inner door is installed in the cabinet, which can play a protective role during normal use, avoiding injury to operators during maintenance and repair. The window also facilitates the operation of the circuit breaker. The inner door can also be opened for maintenance.
