Description

Technical Field

[0001] The utility model relates to the technical field of power control cabinets, in particular to a temperature acquisition device for power control cabinets. Background Technique

[0002] A control cabinet is a device that assembles switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet according to electrical wiring requirements, and is commonly used in various power generation, distribution, and substation; when powered on and running, the electrical switches inside the control cabinet will generate heat, causing the temperature of the internal environment of the cabinet to rise, and in severe cases, it will cause a fire inside the cabinet. Therefore, it is necessary to collect, monitor, and cool down the temperature inside the control cabinet;

[0003] In the prior art, the temperature acquisition devices for power control cabinets have relatively fixed installation positions and a small number of acquisition units. Since the electrical switches in the cabinet are distributed on different layers, the acquisition units cannot collect accurate and effective temperature data, and lack an over-temperature alarm function. For this reason, we propose a temperature acquisition device for power control cabinets. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a temperature acquisition device for power control cabinets, which has a flexible installation unit. The installation rods on both sides cooperate with the straight slots vertically arranged in an array, so that the temperature sensors installed on the back side of the cabinet door are distributed in a rectangle, and can effectively collect the temperature of each part of the space inside the cabinet. Moreover, the distance between the temperature sensors in each column is adjustable, so that the corresponding positions of the temperature sensors can be adjusted according to the actual installation positions of the electrical switches in the cabinet, making the obtained temperature data more accurate; it also has a reliable temperature monitoring unit, which can process and display the data detected by the temperature sensors, and monitor the temperature data in real time, and can issue an alarm prompt after the temperature exceeds the warning value, effectively solving the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A temperature acquisition device for power control cabinets, including a cabinet door, a flexible installation unit, and a temperature monitoring unit;
