Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, in particular to a switch cabinet with a temperature monitoring mechanism. Background Art

[0002] Switchgear with temperature monitoring mechanism, which realizes real-time monitoring and control of the temperature of key internal components through integrated temperature monitoring mechanism, ensures the safety and stability of the switchgear during operation. It plays an important role in the power distribution system and is widely used in various power distribution systems, such as power plants, substations, industrial plants and other places.

[0003] However, there are still some problems when using the existing switch cabinet with temperature monitoring mechanism:

[0004] There is a switch cabinet with a monitoring function, for example, the Chinese patent application number 201520126646.4. The switch cabinet is equipped with a humidity sensor, a temperature sensor, a central controller, a text message sending module, an automatic power-off switch, and an automatic fire extinguisher. The switch cabinet and the cabinet door are equipped with a door status monitoring switch for detecting the cabinet door status. The nozzle of the automatic fire extinguisher is equipped with a solenoid valve. The humidity sensor, temperature sensor, and door status monitoring switch are connected to the central controller and transmit the detection signal to the central controller in real time. The central controller controls the text message sending module, the automatic power-off switch, and the solenoid valve on the automatic fire extinguisher. It has a simple structure, is easy to use and install, is simple to operate, and has low cost. It can monitor the working status of the switch cabinet in real time, automatically extinguish a fire when it occurs in the switch cabinet, and automatically disconnect the circuit in the switch cabinet when the switch cabinet is flooded. It can also alarm when someone damages the power facilities in the switch cabinet.

[0005] 1. Although existing switchgear has temperature detection functions, they are usually enclosed to ensure electrical safety. This structure restricts the natural flow of air, causing the temperature inside the cabinet to rise easily. High temperatures can adversely affect the current carrying capacity of the switch components and conductors inside the cabinet, and even affect the stable operation and life of the equipment. When the temperature inside the cabinet is too high, it is easy to cause heat accumulation inside the cabinet, resulting in short circuit problems.

[0006] 2. The existing switch cabinets have filters installed in the ventilation area. Although they can prevent some dust from entering the cabinet, it is not convenient to scrape, clean, and collect dust from the filters. As a result, the filters in the ventilation area are prone to dust accumulation after long-term use, resulting in reduced ventilation efficiency and aggravated temperature rise in the cabinet.

[0007] 3. Existing switch cabinets can usually only be inspected inside the cabinet by opening the cabinet door. This method requires power outage during the inspection and may involve complicated disassembly and installation processes. It is not only time-consuming and labor-intensive, but may also increase operational risks. In addition, the space is small, making it difficult for workers to maneuver inside the cabinet and inconvenient for inspecting components and circuits.

[0008] In response to the above problems, an innovative design was carried out based on the original switch cabinet with temperature monitoring mechanism. Summary of the Invention

[0009] The purpose of the present invention is to provide a switch cabinet with a temperature monitoring mechanism to solve the problem raised in the above background technology that although the existing switch cabinet has a temperature detection function, it cannot dissipate heat inside the cabinet and the space is small, making it inconvenient for staff to inspect and repair the interior of the cabinet.
