Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet that can provide high-temperature alarm for circuit breakers. Background Art

[0002] A distribution cabinet is an electrical device used to distribute and control electrical energy, widely used in industrial, commercial, and civil buildings. It primarily distributes electrical energy from a power source to various electrical devices or lines, and provides necessary protection and control functions. Distribution cabinets typically contain various electrical components, such as circuit breakers, contactors, relays, fuses, and meters.

[0003] Patent publication number CN221201047U discloses a circuit breaker and distribution cabinet, including a circuit breaker body and a suspension plate disposed on one side of the circuit breaker body for mounting the circuit breaker body. A locking element is mounted on the suspension plate, and a driving element is also provided on the circuit breaker body facing the suspension plate for locking with the locking element. Moving the driving element slides on the suspension plate to lock with the locking element, completing the assembly of the circuit breaker body. While this patent utilizes the spring force to allow the driving rod to slide and reset within the support cylinder, ultimately locking the locking plate and the locking end, thus quickly achieving circuit breaker body installation, in practical applications, the circuit breaker generates heat during operation, leading to high temperatures. Furthermore, the lack of a high-temperature alarm function prevents timely notification of personnel to take appropriate measures, potentially causing the circuit breaker to spontaneously combust due to overheating, thus posing a safety risk.

[0004] Therefore, a distribution cabinet capable of providing high-temperature alarms for circuit breakers is needed. Summary of the Invention

[0005] In order to overcome the shortcomings of existing patents, such as the generation of heat during circuit breaker operation leading to high temperatures, and the lack of a high-temperature alarm function, which prevents timely notification of staff to take appropriate measures, potentially causing the circuit breaker to spontaneously combust due to overheating and thus posing a safety risk, this utility model provides a distribution cabinet that can provide a high-temperature alarm for the circuit breaker.

[0006] The technical implementation scheme of this utility model is as follows: A distribution cabinet capable of providing high-temperature alarm for circuit breakers includes a cabinet body, hinges, a cabinet door, vertical mounting plates, horizontal mounting plates, a circuit breaker, and branch switches. Two inlet holes are provided at the top of the cabinet body, and multiple outlet holes are provided at the bottom. Multiple hinges are installed on the left side of the cabinet body, and these hinges are rotatably connected to the cabinet door. Two vertical mounting plates are installed inside the cabinet body, and these two vertical mounting plates are fixedly connected to two horizontal mounting plates. A circuit breaker is installed on the upper horizontal mounting plate, and multiple branch switches are installed on the lower horizontal mounting plate. The cabinet also includes a heat-conducting plate, a flexible temperature sensor, a controller, a signal transmitting module, and a buzzer. The heat-conducting plate is fixedly connected inside the cabinet body, and it contacts the circuit breaker and branch switches. A flexible temperature sensor is installed on the heat-conducting plate. A controller is located on the front side of the cabinet body, and the flexible temperature sensor is signal-connected to the controller. A signal transmitting module is installed on the controller. A buzzer is located on the front side of the cabinet body, and the buzzer is electrically connected to the controller.

[0007] In a preferred embodiment of this utility model, a fixing plate and an exhaust fan are also included. The fixing plate is fixedly connected to the front side of the cabinet interior, and two exhaust fans are installed on the fixing plate. The exhaust fans are connected to the controller via signal.

[0008] In a preferred embodiment of this utility model, it further includes a rotating shaft, a leaf plate, an electric slide rail, an electric slider, a connecting rod, a guide frame, and levers. Multiple rotating shafts are rotatably arranged on the front side of the cabinet, and leaf plates are fixedly connected to the rotating shafts. A guide groove is opened at the bottom of the leaf plate. An electric slide rail is arranged inside the cabinet, and an electric slider is slidably arranged on the electric slide rail. A connecting rod is fixedly connected to the front side of the electric slider. A guide frame is slidably arranged on the front side of the cabinet, and multiple levers are fixedly connected to the guide frame. The levers are slidably connected to the guide grooves.

[0009] In a preferred embodiment of this utility model, it further includes an air storage tank, a one-way valve, a nozzle, an air outlet pipe, an electric valve, and a connecting pipe. An air storage tank is installed inside the cabinet. A one-way valve is installed on the top of the air storage tank. An air outlet pipe is connected and communicated to the front of the air storage tank. An electric valve is installed on the air outlet pipe. One end of the air outlet pipe is connected and communicated to two connecting pipes. An air outlet pipe is installed on the connecting pipe. A nozzle is installed on the air outlet pipe.

[0010] In a preferred embodiment of this utility model, a strobe light is also included, and a strobe light is provided on the top of the cabinet.

[0011] In a preferred embodiment of the present invention, a rubber sleeve is also included, with both the inlet hole and the outlet hole being provided with rubber sleeves.

[0012] Compared with the prior art, this utility model provides a distribution cabinet that can alarm for high temperature of circuit breakers, which has the following beneficial effects: when the temperature sensed by the flexible temperature sensor exceeds the normal value, it will send a signal to the controller. After receiving the signal, the controller will start the signal transmission module and the buzzer. The signal transmission module will run and send a signal to the terminal device, and the buzzer will sound to issue an alarm, thereby reminding the staff to take timely measures to avoid safety accidents.

[0013] Turn on the exhaust fan. The exhaust fan generates negative pressure, which accelerates the removal of heat from inside the cabinet, thereby dissipating heat from the inside of the cabinet and preventing the temperature from getting too high and affecting the normal operation of the distribution cabinet.

[0014] The connecting rod and guide frame move upward, causing the lever to press the leaf plate outward and seal the cabinet's exhaust port, preventing outside air from entering the cabinet and isolating oxygen.

[0015] By opening the electric valve, the gas outlet pipe is opened, and the nitrogen gas inside the gas storage tank enters the connecting pipe through the gas outlet pipe, and then is sprayed into the cabinet through the nozzle, thereby reducing the risk of fire and explosion.

[0026] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0027] Example 1: A distribution cabinet capable of providing high-temperature alarms for circuit breakers. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7The system includes a cabinet body 1, hinges 2, cabinet doors 3, vertical mounting plates 301, horizontal mounting plates 4, circuit breakers 5, and branch switches 6. The top of the cabinet body 1 has two inlet holes 101, and the bottom of the cabinet body 1 has one outlet hole 102. Three hinges 2 are bolted to the left side of the cabinet body 1, and these three hinges 2 are rotatably connected to the cabinet door 3. Inside the cabinet body 1, two vertical mounting plates 301 are bolted together, and these two vertical mounting plates 301 are fixedly connected to two horizontal mounting plates 4. The upper horizontal mounting plate 4 has the circuit breaker 5, and the lower horizontal mounting plate 4 has several branch switches 6. A heat-conducting plate 7 is fixedly connected inside the cabinet body 1, and the heat-conducting plate 7 is connected to the circuit breaker 5 and the branch switches 6. The cabinet 1 has a contact point 6. A flexible temperature sensor 8 is installed on the heat-conducting plate 7. A controller 9 is installed on the front side of the cabinet 1. The flexible temperature sensor 8 is connected to the controller 9. A signal transmitting module 901 is installed on the controller 9. A buzzer 10 is installed on the front side of the cabinet 1. The buzzer 10 is electrically connected to the controller 9. A strobe light 11 is installed on the top of the cabinet 1. The strobe light 11 is electrically connected to the controller 9. After receiving a signal, the controller 9 controls the strobe light 11 to light up and flash, thereby attracting the attention of pedestrians and reminding them not to approach. Rubber sleeves 28 are installed on the inlet hole 101 and the outlet hole 102. The rubber sleeves 28 reduce the gap between the connecting wire and the inlet hole 101 and the outlet hole 102 to prevent dust from entering the interior of the cabinet 1.

[0028] When the distribution cabinet is needed, first turn the cabinet door 3 outward to open the cabinet body 1. Pass the connecting wire through the inlet hole 101 into the cabinet body 1 and connect the connecting wire to the circuit breaker 5 and the branch switch 6. Then, pass the connecting wire through the outlet hole 102 to connect with other electronic equipment. After the connection is completed, turn the cabinet door 3 inward to close the cabinet body 1. Then, introduce nitrogen into the gas storage tank 12 through the one-way valve 13. When using the distribution cabinet, start the flexible temperature sensor 8 and the controller 9. When the circuit breaker 5 and the branch switch 6 are hot, the heat will be transferred to the heat conduction plate 7. The flexible temperature sensor 8 detects the temperature on the heat conduction plate 7. If the detected temperature exceeds the normal value, it will send a signal to the controller 9. After receiving the signal, the controller 9 starts the signal transmission module 901 and the buzzer 10. The signal transmission module 901 runs and transmits a signal to the terminal equipment. The buzzer 10 sounds to issue an alarm, thereby reminding the staff to take timely measures to avoid safety accidents.

[0029] Example 2: Based on Example 1, please refer to... Figure 4 A fixing plate 18 is fixedly connected to the front side of the cabinet 1. Two exhaust fans 19 are installed on the fixing plate 18 by bolt connection. The exhaust fans 19 are connected to the controller 9 by signal.

[0030] After the buzzer 10 sounds to issue an alarm, the controller 9 automatically turns on the exhaust fan 19. The exhaust fan 19 generates negative pressure, which accelerates the heat dissipation inside the cabinet 1, thereby cooling the inside of the cabinet 1 and preventing the temperature from being too high and affecting the normal operation of the power distribution cabinet.

[0031] Please see Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The cabinet 1 has several rotating shafts 20 on its front side, and leaf plates 21 are fixedly connected to the rotating shafts 20. The bottom of the leaf plates 21 is provided with guide grooves 22. The cabinet 1 is equipped with an electric slide rail 23, and an electric slider 24 is slidably installed on the electric slide rail 23. A connecting rod 25 is fixedly connected to the front of the electric slider 24. A guide frame 26 is slidably installed on the front of the cabinet 1, and multiple levers 27 are fixedly connected to the guide frame 26. The levers 27 are slidably connected to the guide grooves 22.

[0032] After the heat inside the cabinet 1 is discharged, the electric slide rail 23 is activated, and the electric slider 24 is controlled to move upward. The movement of the electric slider 24 drives the connecting rod 25 and the guide frame 26 to move upward, which in turn causes the lever 27 to press the leaf plate 21 to rotate outward, sealing the exhaust port of the cabinet 1, preventing external air from entering the cabinet 1 and isolating oxygen.

[0033] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 The cabinet 1 is also equipped with a gas storage box 12. A one-way valve 13 is installed on the top of the gas storage box 12. A gas outlet pipe 15 is connected to the front of the gas storage box 12. An electric valve 16 is installed on the gas outlet pipe 15. One end of the gas outlet pipe 15 is connected to two connecting pipes 17. A gas outlet pipe 15 is installed on the connecting pipes 17. A nozzle 14 is installed on the gas outlet pipe 15. Before using the gas storage box 12, that is, before starting the power distribution cabinet, nitrogen is first introduced into the gas storage box 12 through the one-way valve 13 for gas storage.

[0034] After sealing the exhaust port of cabinet 1, open the electric valve 16 to open the exhaust pipe 15. The nitrogen gas inside the gas storage tank 12 enters the connecting pipe 17 through the exhaust pipe 15 and is then sprayed into the cabinet 1 through the nozzle 14, thereby reducing the risk of fire and explosion.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
