Description

Technical Field

[0001] This utility model relates to the field of power supply monitoring technology, specifically a monitoring device for a smart microgrid power supply system. Background Technology

[0002] A smart microgrid is a miniaturized, independent power system composed of distributed power sources, energy storage devices, energy conversion devices, related loads, and monitoring and protection devices. It can achieve self-control, protection, and management, and can operate in parallel with the external power grid or in isolation. During the operation of a smart microgrid, detection equipment is required to monitor the power system in real time.

[0003] Power monitoring equipment in smart microgrids is a system used to monitor and control the generation, storage, distribution, and use of electricity within the smart microgrid. This equipment ensures the efficient and stable operation of the microgrid and optimizes energy management.

[0004] Most current monitoring equipment is used to monitor electrical parameters such as current, voltage, frequency, and power factor, but it neglects the monitoring of its own environment and cannot provide more comprehensive system management. At the same time, the monitoring devices cannot cope with sudden accidents, such as hardware damage caused by short circuits or overloads, or even explosions, which can cause significant economic losses and chain reactions, resulting in a series of emergencies.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a monitoring device for a smart microgrid power supply system to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a housing and a mounting bracket installed on one side of the inner wall of the housing. A circuit connector is connected to one side of the mounting bracket. A monitoring unit is connected to one side of the inner wall of the housing. A temperature sensor, a humidity sensor, and a communication connection terminal are connected to one side of the inner wall of the housing. An explosion-proof assembly is connected to one side of the inner wall of the housing. A backup circuit breaker is internally connected to the explosion-proof assembly. A lightning protection element is connected to the top of the housing. A door panel is rotatably mounted on the front of the housing. A security slot is connected to one side of the door panel. A backup electronic component is internally connected to the security slot. An external mounting shell is connected to the other side of the door panel. A backup controller and a wireless communicator are internally connected to the external mounting shell.

[0008] Preferably, a protective plate is connected to one side of the external mounting shell.

[0009] Preferably, a mounting bracket is connected to the back of the housing.

[0010] Preferably, the explosion-proof component includes an outer shell, an inner liner connected inside the outer shell, a ceramic heat insulation layer filled between the outer shell and the inner liner, reinforcing corner brackets connected at the four corners of the inner wall of the inner liner, a support frame connected between the inner walls of the inner liner, and an explosion-proof cover plate fitted into one side of the outer shell.

[0011] Preferably, an electromagnet is connected to one side of the top of the inner wall of the box, and a permanent magnet is connected to one side of the door panel corresponding to the electromagnet.

[0012] Preferably, the monitoring unit includes current monitoring, voltage monitoring, frequency monitoring, and power factor monitoring sensors.

[0013] Preferably, a shockproof cover is fitted and connected to one side of the socket, and the spare electronic components and spare controller are electrically connected to the spare circuit breaker.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] Temperature and humidity sensors monitor the internal temperature and humidity of the enclosure in real time. When the temperature or humidity is too high, the system sends a signal to the control backend via the communication connection for comprehensive monitoring and to provide more complete system information. In the event of a short circuit, overload, or explosion, the system can send a control signal to the backup controller via a wireless communicator. The backup circuit breaker will then activate the backup electronic components to continue monitoring the microgrid. This allows for timely response to unexpected events, reduces damage caused by chain reactions, and effectively improves operational safety. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides a technical solution: it includes a housing 1 and a fixing frame 2 installed on one side of the inner wall of the housing 1. A circuit connector 3 is connected to one side of the fixing frame 2. The circuit connector 3 is a component used for circuit connection in existing power supply monitoring devices, or it can be a phasor measurement unit (a basic test system that samples the voltage, current, power, and frequency of the power grid, typically sampling 60 times per second. These devices use embedded GPS modules for synchronous measurement and transmission of monitoring data on power transmission in the power grid, monitoring PMU). A monitoring unit 4 is connected to one side of the inner wall of the housing 1. The monitoring unit 4 includes sensors for current monitoring, voltage monitoring, frequency monitoring, and power factor monitoring, used to monitor power parameters such as current, voltage, frequency, and power factor. A temperature sensor 5 and a humidity sensor 6 are also connected to one side of the inner wall of the housing 1. Communication connection terminal 7 allows data transmission between devices and with the remote monitoring system. An explosion-proof component 8 is connected to one side of the inner wall of the enclosure 1. A backup circuit breaker 9 is connected inside the explosion-proof component 8. The circuit inside the enclosure 1 is electrically connected to the backup circuit breaker 9. The backup circuit breaker 9 is electrically connected to the backup electronic component 13. A lightning protection component 10 is connected to the top of the enclosure 1. A door panel 11 is rotatably mounted on the front of the enclosure 1. A mounting slot 12 is connected to one side of the door panel 11. A backup electronic component 13 is connected inside the mounting slot 12. The backup electronic component 13 includes the basic components of the entire power supply monitoring system. Since it is a conventional technology, it is not described in detail in the manual. An external mounting shell 14 is connected to the other side of the door panel 11. A backup controller 15 and a wireless communicator 16 are connected inside the external mounting shell 14.

[0022] Reference Figure 1 As shown, a protective plate 17 is connected to one side of the outer mounting shell 14 to protect the internal backup controller 15 and wireless communicator 16, thus achieving the effect of waterproofing and dustproofing.

[0023] Reference Figure 1 As shown, a mounting bracket 18 is connected to the back of the housing 1 for installing the device in a suitable position.

[0024] Reference Figure 3 As shown, the explosion-proof component 8 includes a housing 81, an inner liner 82 connected inside the housing 81, a ceramic heat insulation layer 83 filled between the housing 81 and the inner liner 82, reinforcing corner brackets 84 connected at the four corners of the inner wall of the inner liner 82, and a support frame 85 connected between the inner walls of the inner liner 82. An explosion-proof cover plate 86 is fitted into one side of the housing 81. The housing 81 and the inner liner 82 form a multi-layer protection effect. The ceramic heat insulation layer 83 in the middle provides protection against fire or high temperature. Together with the internal reinforcing corner brackets 84 and support frame 85, it provides good protection for the standby circuit breaker 9.

[0025] Reference Figure 2 As shown, an electromagnet 19 is connected to one side of the top of the inner wall of the enclosure 1, and a permanent magnet 20 is connected to one side of the door panel 11 corresponding to the electromagnet 19. The door panel 11 is tilted outwards, which facilitates the opening and closing of the door panel 11 during normal use. In case of an accident, the electromagnet 19 loses power and loses its attraction to the permanent magnet 20, so the door panel 11 opens automatically, taking out the spare electronic components 13 inside and leaving the environment inside the enclosure 1.

[0026] Reference Figure 2 As shown, a shockproof cover plate 131 is fitted and connected to one side of the slot 12. The spare electronic component 13 and the spare controller 15 are electrically connected to the spare circuit breaker 9. In the event of an explosion, the shockproof cover plate 131 can provide a certain degree of protection for the internal spare electronic component 13.

[0027] The implementation principle of this application is as follows: When in use, the internal temperature sensor 5 and humidity sensor 6 monitor the temperature and humidity inside the enclosure 1 in real time. When the temperature and humidity are too high, they send a signal to the control backend via the communication connection terminal 7. Personnel can then take timely action to prevent the device from being damaged by the environment. In the event of a short circuit or overload that damages or explodes the components inside the enclosure 1, the electromagnet 19 is de-energized, the door 11 opens automatically, and the backup circuit breaker 9 inside the enclosure 1 is protected by the explosion-proof component 8 to prevent the backup electronic component 13 from being affected. The backend can send a control signal to the backup controller 15 via the wireless communicator 16, thereby activating the backup electronic component 13 to continue monitoring the microgrid and abandoning the use of the damaged components inside the enclosure 1, thus achieving the effect of timely backup.
