Description

Technical Field

[0001] The utility model relates to the technical field of high and low voltage cabinets, in particular to a high and low voltage cabinet with overheating early warning. Background Art

[0002] High and low voltage cabinets refer to complete sets of equipment used in power systems to control, protect, measure and distribute electric energy for high and low voltage electrical equipment. They are usually composed of metal casings, components, control devices and connecting lines, and are widely used in power systems of power plants, substations, industrial and mining enterprises and various buildings.

[0003] The components inside the high and low voltage cabinets will generate heat during operation, and this heat is generally discharged by cooling fans. However, when a component fails, a large amount of heat will be generated, causing the temperature inside the cabinet to rise rapidly. At this time, maintenance personnel are required to promptly inspect and maintain the electrical components inside the distribution cabinet.

[0004] In order to enable maintenance personnel to detect abnormal temperature inside the distribution cabinet in time, a temperature sensor that detects the temperature inside the cabinet in real time is fixedly installed inside the cabinet. When the temperature inside the cabinet is abnormal, an alarm is sounded, so that maintenance personnel can detect overheating problems of the distribution cabinet in time. However, this existing early warning method can only sound an alarm but cannot directly reflect the faulty and hot electrical components of the distribution cabinet and take corresponding measures, which poses potential safety problems. In addition, maintenance personnel need to spend a lot of time to detect each component, and their work efficiency is low. Utility Model Content

[0029] Example 2

[0030] See also Figure 1-4 This embodiment is a further improvement made on the basis of Embodiment 1. Compared with Embodiment 1, the moving mechanism 5 is further described, wherein the lateral moving component 51 of the moving mechanism 5 is installed in the dustproof shell 6, and an active opening 13 is opened at the top of the cabinet 1 and located inside the dustproof shell 6, and the vertical moving component 52 extends into the dustproof shell 6 through the active opening 13 and is connected with the lateral moving component 51.

[0031] The lateral movement assembly 51 includes a first drive motor 511, which is fixedly mounted on the dustproof housing 6. The output shaft of the first drive motor 511 is fixedly connected to a first threaded rod 512, on which a first moving block 513 is threadedly connected, and on which a first limiting rod 514 is inserted and slidably connected, and the first threaded rod 512 and the first limiting rod 514 are both connected to the side wall of the dustproof housing 6, and the bottom of the first moving block 513 is connected to the vertical movement assembly 52. ​​When the first drive motor 511 is powered on, it drives the first threaded rod 512 to rotate, and through the cooperation of the first limiting rod 514, the first moving block 513 drives the vertical movement assembly 52, the infrared temperature detector 3 and the radiator 4 to move horizontally.
