Description

Technical Field

[0001] The utility model relates to the field of switch cabinets, in particular to a switch cabinet based on a controllable constant temperature platform. Background Art

[0002] Switchgear is a widely used electrical equipment. The main function of the switchgear is to open and close / control and protect electrical equipment during the system's power generation, transmission, distribution and power conversion. The structure of the switch is mainly divided into a control room and a feeder room and is separated by a mounting plate. In order to ensure the normal operation of the electrical equipment, the switchgear also has the function of temperature control and constant temperature. For example, electrical equipment in a high temperature environment will cause damage to the equipment and lines due to excessive temperature. In a humid environment, moisture will adhere to the surface of the electrical equipment, causing damage to the equipment and lines. It can be seen that excessively high or low temperature will cause electrical equipment failures. Therefore, in order to allow the electrical equipment inside the switchgear to operate normally, it is necessary to design a temperature-controllable switchgear. In order to make the interior of the switchgear uniform and stable, the existing temperature-controlled switchgear is equipped with multiple ventilators. This design structure makes equipment maintenance difficult and the structure is also complex. Therefore, it is necessary to design a switchgear based on a controllable constant temperature platform.

By arranging the insulation layer 3, an air barrier is left between the cabinet frame 1 and the insulation layer 3. The air barrier can reduce the speed of temperature reduction, thereby improving the insulation effect of the installation chamber 2. By arranging the ventilation mechanism 5 and the temperature detector 7, the ventilation mechanism 5 generates airflow to enter the interior of the installation chamber 2, so that the air flow speed is increased, which plays a role in cooling the electrical equipment. The temperature detector 7 detects the temperature in the installation chamber 2. When the temperature exceeds the preset value of the temperature detector 7, the ventilation mechanism 5 is started, thereby ensuring that the interior of the installation chamber 2 maintains a constant temperature, and the safety performance of the cabinet frame 1 is improved through the cabinet door 13.

[0022] In an embodiment of the utility model, a ventilation chamber 8 is provided at the bottom of the cabinet frame 1, and a ventilation plate 9 is installed on one side of the ventilation chamber 8. By providing the ventilation chamber 8 and the ventilation plate 9, external air enters the ventilation plate 9 and then enters the ventilation chamber 8, so that the air flow speed between the insulation layer 3 and the cabinet frame 1 is increased, and the cooling effect of the switch cabinet is improved.
