Abstract
Description
Technical Field
[0001] This utility model relates to the field of switchgear technology, specifically a comprehensive monitoring and diagnostic device for switchgear. Background Technology
[0002] In power systems, switchgear, as a key device for power distribution and control, directly impacts the reliability of the entire power grid through its operational safety and stability. However, existing switchgear faces numerous challenges during operation. Firstly, the internal electrical components are susceptible to environmental factors during long-term operation. For instance, high humidity levels can cause insulation components to become damp and age, potentially leading to short-circuit faults. Dust accumulation can also result in poor heat dissipation and increased contact resistance, seriously threatening equipment safety. Secondly, traditional switchgear relies heavily on manual inspections for condition monitoring, which is not only inefficient and costly but also fails to capture subtle changes in key parameters such as temperature and humidity in real time, making it difficult to detect potential faults promptly. Once a fault occurs, it often causes widespread power outages, resulting in significant economic losses and social impact. Furthermore, existing monitoring devices are functionally limited and lack comprehensive control over environmental and equipment conditions, failing to meet the demands of modern power systems for intelligence and reliability. Utility Model Content

[0029] The specific application scenario of this embodiment is as follows: The switch cabinet 100 serves as the main frame and is connected to the movable door 110 via hinges, facilitating personnel to operate and maintain the internal power distribution equipment; the power distribution support plate 160 provides an installation surface for the power distribution equipment, ensuring the equipment's stability; in the integrated testing component, the fan 220 inside the housing 200 generates airflow, which is diverted to the manifold 262 via the main air duct 261 on the top cover 260; the fan drives the airflow, forming forced convection, providing power for heat dissipation or the delivery of dry air inside the switch cabinet; the manifold 262 directs the airflow to various areas within the switch cabinet, achieving gas regulation of the surrounding environment of the power distribution equipment, such as cooling and dehumidification, creating a suitable environment for subsequent monitoring and diagnosis.
[0030] Example 2: Figure 1 and Figure 2 Support legs 150 are fixedly installed at the four corners of the bottom of the switch cabinet 100. Vent valves 120 are fixedly installed on the top outer wall of the switch cabinet 100. Two vent valves 120 are symmetrically arranged on the left and right. Display screen 130 is fixedly installed on the front outer wall of the movable door 110. Operation buttons 140 are fixedly installed below the display screen 130.
[0031] The specific application scenario of this embodiment is as follows: the support legs 150 provide stable support for the switch cabinet 100, preventing the equipment from directly contacting the ground, preventing moisture and facilitating the laying of bottom cables. The ventilation valves 120 are symmetrically arranged on the left and right sides to realize the circulation of air between the inside and outside of the switch cabinet, balance the internal and external air pressure, and prevent large dust particles from entering. The display screen 130 on the movable door 110 is used to display the operating parameters of the switch cabinet, fault alarm information or diagnostic results. The operation buttons 140 are used by the operator to set monitoring parameters, start diagnostic programs or control the equipment. Through the display screen and operation buttons, human-machine interaction is realized, which makes it convenient for personnel to grasp the status of the switch cabinet in real time and intervene.
[0032] Example 3: Figure 5 The housing 200 is fixedly installed on the bottom inner wall of the switch cabinet 100. The bottom end of the housing 200 extends to the outside of the switch cabinet 100. A dust filter element 210 is fixedly installed on the bottom inner wall of the housing 200. Several fans 220 are provided and distributed along the length of the housing 200. A sliding groove 230 is opened on the top side wall of the housing 200. A desiccant box 240 is slidably connected to the inner wall of the sliding groove 230. Through holes are evenly opened on the bottom inner wall of the desiccant box 240. A desiccant 250 is inserted and installed inside the desiccant box 240. The desiccant 250 is located above the fans 220. Several manifolds 262 are provided and are adapted to the top space of the power distribution support plate 160. A nozzle 264 is fixedly installed at the end of the manifold 262. A solenoid valve 263 is fixedly installed on the outer wall of the manifold 262. The outer surfaces of the main air duct 261 and the manifolds 262 are fixedly installed on the inner wall of the switch cabinet 100 through the support bracket 270.
[0033] The specific application scenario of this embodiment is as follows: The dust filter element 210 at the bottom of the housing 200 filters the air entering the interior, preventing dust from entering and affecting the normal operation of components such as the fan 220. Multiple fans 220 distributed along the length enhance the airflow effect and ensure gas delivery efficiency. The desiccant 250 in the desiccant box 240 absorbs moisture in the airflow. Driven by the fan, the dry air is delivered to the switch cabinet through the main air duct 261 and manifold 262 to reduce the internal humidity and prevent electrical components from short-circuiting or other malfunctions due to moisture. The solenoid valve 263 controls the airflow of the manifold 262. According to actual needs, such as when the humidity exceeds the standard, it is turned on. The nozzle 264 accurately sprays dry air onto key areas such as the power distribution support plate 160. The support 270 fixes the main air duct 261 and manifold 262 to ensure the stability of the gas transmission system and realize the dynamic control and precise management of the humidity environment inside the switch cabinet.
[0034] Example 4: Figure 3 and Figure 4 Detectors 300 are fixedly installed on the top inner wall of switch cabinet 100 and the bottom outer wall of power distribution support plate 160. Two detectors 300 are symmetrically arranged on the left and right sides. Temperature sensor 310 and humidity sensor 320 are fixedly installed on the bottom outer wall of detector 300.
[0035] The specific application scenario of this embodiment is as follows: Detectors 300, symmetrically installed on the top inner wall of switchgear 100 and the bottom outer wall of power distribution support plate 160, work with temperature sensor 310 and humidity sensor 320 to collect temperature and humidity data at different locations inside the switchgear in real time. Temperature sensor 310 monitors the heat generated during equipment operation to determine whether there is a risk of overheating leading to insulation aging, equipment damage, etc. Humidity sensor 320 detects the ambient humidity to avoid problems such as corrosion of electrical components and short circuits caused by excessive humidity. After preliminary processing of the data collected by the sensors, detectors 300 transmit the data to the control system or display it on the display screen 130 to provide basic data for the status diagnosis of the switchgear, so as to detect potential faults in a timely manner and take countermeasures.

In the integrated detection component, the fan 220 inside the housing 200 generates airflow, which, after being filtered by the dust filter element 210 and dehumidified by the desiccant 250, flows through the main air duct 261 and manifold 262, and then... The solenoid valve 263 controls the airflow and humidity regulation of the cabinet through the nozzle 264. The display screen 130 and operation buttons 140 form a human-machine interface for easy parameter setting and information viewing.
