Description

Technical Field

[0001] This utility model relates to the technical field of power equipment monitoring, and in particular to an intelligent monitoring device for a relay protection cabinet. Background Technology

[0002] Relay protection cabinets play a crucial role in power systems. By monitoring the operating status of the power system in real time, they can promptly detect and determine the type, location, and extent of faults. The main function of relay protection cabinets is to act quickly when power equipment malfunctions or fails, cutting off faulty components or circuits to prevent the fault from spreading and affecting other equipment, thus ensuring the stable operation of the power grid. This not only effectively prevents equipment damage but also ensures the safety and reliability of the power system, providing a strong guarantee for the continuity of power transmission.

[0003] In existing technologies, the operation status of relay protection cabinets mainly relies on regular manual inspections. This traditional inspection method not only suffers from poor timeliness but also fails to achieve real-time monitoring of the equipment. Environmental factors within the relay protection cabinet, such as abnormal changes in temperature and humidity, may lead to condensation inside the equipment, component aging, performance degradation, and even malfunctions such as false tripping, seriously affecting the stability and safety of the equipment. In addition, unauthorized opening of the cabinet door or operational errors can also pose certain safety hazards. Although some existing monitoring devices have certain monitoring functions, they are often limited in function, have low integration, and are inconvenient to install, failing to fully meet the needs of smart grids for real-time perception and monitoring of equipment status. These devices lack effective local and remote alarm mechanisms, failing to issue timely warnings for potential problems, thus failing to provide timely protection for equipment maintenance and fault prevention. Utility Model Content

[0004] In view of the aforementioned problems of poor timeliness and inadequate real-time monitoring of equipment, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an intelligent monitoring device for relay protection cabinets.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0020] Reference Figures 1-2 This is the first embodiment of the present invention, which provides an intelligent monitoring device for a relay protection cabinet. The intelligent monitoring device for the relay protection cabinet includes a housing 1 and a control motherboard disposed in the housing 1. The control motherboard integrates a main control MCU 5, and the input terminal of the main control MCU 5 is connected to an environmental monitoring module 6, a door status detection module 7 and a power supply module 8. By integrating each functional module around the main control MCU, the modular and integrated design of the device is achieved; The output of the main control MCU5 is connected to the local alarm module 9 and the communication module 10; The local alarm module ensures that an immediate warning can be issued on-site to alert nearby personnel; the communication module enables remote monitoring, extending the monitoring range of the device from the local area to the remote operation and maintenance center, forming a dual protection system of "local and remote", which greatly improves the speed of accident response. Environmental monitoring module 6 includes temperature and humidity sensors and condensation sensors; Temperature and humidity sensors can monitor the basic conditions of the operating environment inside the cabinet, preventing equipment from degrading or being damaged due to overheating or humidity; condensation sensors are specifically designed to detect condensation that may occur inside the cabinet, which is a key measure to prevent serious accidents such as short circuits and flashovers caused by insulation degradation, reflecting the targeted and comprehensive nature of the monitoring. Door status detection module 7 is a reed switch sensor or a micro switch; By using mature, low-cost, and reliable sensors such as reed switches or microswitches, accurate and stable detection of the cabinet door's opening and closing status is achieved, effectively preventing unauthorized entry or misoperation and ensuring the safety and physical security of the equipment inside the cabinet. Local alarm module 9 includes an audible and visual alarm; The audible and visual alarm combines sound and light warning signals to ensure that alarm information can be effectively perceived in noisy or poorly lit environments, greatly improving the reliability and warning effect of the alarm. Power module 8 is a wide voltage input power module; The wide voltage input design enables the device to adapt to voltage fluctuations that may occur in different environments, enhancing the device's power supply adaptability and stability, and ensuring reliable operation even in complex power environments.

[0021] The main control MCU5 is also connected to a data storage module 11; The data storage module can record historical environmental data, alarm events, and times, providing important data support for subsequent analysis of accident causes, assessment of equipment operating status, and preventive maintenance.

[0022] The back of housing 1 is provided with a standard guide rail slot 2.

[0023] Standard guide rail slot 2 is a DIN 35mm standard guide rail slot; Like common industrial control components, it can be quickly and easily installed on standard rails of power distribution cabinets and control cabinets, greatly simplifying the installation process, eliminating tedious steps such as drilling and screw fixing, improving installation efficiency, and facilitating subsequent disassembly and maintenance. Example

[0024] Reference Figures 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a ventilation window 3 is opened on the housing 1 at the position corresponding to the temperature and humidity sensor and the condensation sensor. This ensures that the sensors inside the housing can exchange air with the air inside the cabinet fully and quickly, avoiding the impact of the housing on the monitoring accuracy and response speed of the sensors, thereby guaranteeing the authenticity and timeliness of environmental monitoring data.

[0025] The audible and visual alarm includes four high-brightness LED lights and a high-decibel buzzer; High-brightness LED lights and high-decibel buzzers emphasize the strength of the alarm signal, ensuring that the alarm signal remains sufficiently conspicuous and piercing in brightly lit industrial sites or noisy environments, thereby immediately drawing the attention of personnel.

[0026] The communication module 10 is either a 4G / 5G module or a Wi-Fi module.

[0027] The remaining structure is the same as that in Example 1.

[0028] Based on embodiments 1-2, the working principle of this utility model is as follows: After the device is powered on, each sensor continuously collects data and transmits it to the main control MCU5; the main control MCU5 compares the data with preset thresholds; for example, when the temperature exceeds 60℃, the humidity exceeds 85%RH, condensation is detected, or the cabinet door is opened at an unauthorized time, the main control MCU5 will immediately activate the local audible and visual alarm, and at the same time send alarm information to the remote location via the 4G communication module; maintenance personnel can take timely action based on the remote information, effectively preventing accidents from occurring.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
