Description

Technical Field

[0001] The invention relates to the technical field of monitoring and recording, and in particular to an automatic monitoring and recording device for a central cabinet environment. Background Art

[0002] At present, closed 10kV and 35kV central cabinets are widely used in unmanned substations. During the long-term operation of the central cabinet, some components have high thermal power, resulting in serious local heating. After a certain stage, it will cause serious failures and undermine the safety and reliability of power supply. The air humidity in some substations is relatively high all year round. When the central cabinet is operated in this environment, the electrical insulation will be affected, resulting in short circuits and partial discharge accidents. At present, the monitoring of the central cabinet is mostly based on manual inspections. During the operation of the trolley switch, only the local situation in the cabinet can be observed through the observation window. Due to the increasingly complex structure of the central cabinet and the shielding of components, the central cabinet is prone to failure. The use of handheld infrared thermometers cannot comprehensively and accurately measure the equipment and environmental parameters in the cabinet. In particular, some important load switch cabinets lack unified and effective monitoring methods. The equipment operation status can only be determined through regular inspections and temperature measurements. The inspection time interval is too long compared to the fault development time, which is bound to cause safety hazards in the operation of the switch cabinet. Conventional monitoring methods cannot detect potential defects in the central cabinet, let alone determine the development trend of defects. Some minor faults cannot be discovered and eliminated in time, which will have a negative impact on safe production and may cause greater losses. Therefore, it is necessary to automatically monitor the interior of the central cabinet;

[0003] When the automatic monitoring and recording device for the central cabinet environment is in use, the central cabinet cannot be automatically monitored in real time, making it impossible for staff to monitor the use of electronic components in the central cabinet in detail, making the central cabinet prone to danger. At the same time, when the automatic monitoring and recording device for the central cabinet environment is in use, usually only a cooling fan is used to dissipate the heat in the cabinet body, resulting in low heat discharge efficiency in the central cabinet and inconvenience in removing moisture in the cabinet body. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides an automatic monitoring and recording device for the environment of a central cabinet. The device utilizes external electronic equipment to start an electric push rod to push a connecting plate to move up and down, and utilizes the movement of the connecting plate to drive a moving seat to move up and down, so that the device can drive an infrared thermal imager to move up and down. The first motor and the second motor are started, and the first motor is used to drive a lead screw to rotate. When the lead screw rotates, the sliding sleeve can drive the moving plate to slide. When the sliding sleeve moves, the guide rod is moved so that the guide rod can guide the movement of the sliding sleeve. The left and right movement of the moving plate can drive the infrared thermal imager to move left and right. The rotation of the second motor is used so that the second motor can drive the roller and the push block to rotate together. The push block is used to fit the movable plate so that the push block can push the movable plate to tilt and toggle to squeeze the first spring, so that the infrared thermal imager can swing left and right. The multi-angle movement of the infrared thermal imager is used so that the infrared thermal imager can monitor the electronic components in the cabinet. The components are monitored in real time, so that the staff can be reminded of the use of the electronic components of the cabinet in time. When the cabinet is placed in use, a spacing plate is used to create a spacing between the cabinet and the wall and multiple cabinets when placed, so that the heat in the cabinet can be discharged normally. When the temperature and humidity in the cabinet exceed the standard, the external electronic equipment can be used to start the cooling fan to rotate. When the cooling fan rotates, since the open box corresponds to the front of the cooling fan, part of the wind blown by the cooling fan can enter the interior of the open box, so that the elastic plate is affected by the wind force in the open box. The second spring can be used to shake on the surface of the support plate to extract moisture from the heat blown out of the cabinet, and the heat in the cabinet can be discharged from the inside of the cabinet in reverse by cooperating with the blowing of the cooling fan. The flow of cabinet heat can be used to dry the moisture in the cabinet, thereby improving the advantages of the device in controlling temperature and humidity, and solving the problems that the central cabinet cannot be monitored in real time and the heat dissipation and dehumidification effect of the central cabinet is poor.
