This can ensure the safe operation of electrical equipment, reduce the damage rate of electrical equipment, reduce power outage time, extend the maintenance cycle of electrical equipment, and improve power supply reliability. Nowadays, with the development and progress of electricity, the use of power transformers is becoming more and more widespread. When power transformers are put into use, the use of power transformer condition inspection intelligent management devices can promote the safe and economical operation of substation system equipment.

After searching, the authorization announcement number CN202940493U discloses an intelligent management device for the status inspection and maintenance of an electric transformer, including an electric transformer operating status signal acquisition circuit, a signal data calculation and judgment processing circuit, a communication circuit, and an intelligent management command center circuit for the status inspection and maintenance of an electric transformer; the electric transformer operating status signal acquisition circuit collects various signal data and outputs them to the signal data calculation and judgment processing circuit, the signal data calculation and judgment processing circuit output is connected to the communication circuit, and the communication circuit is connected to the intelligent management command center for the status inspection and maintenance of an electric transformer; it can monitor the operating technical data of the electric transformer at any time, and promptly discover abnormal conditions such as voltage, current, temperature, etc. of the transformer and the distribution device, and can arrange maintenance in time according to the operating status of the on-site equipment. The power transformer condition inspection and maintenance intelligent management device is usually assembled by installing and fixing a variety of electrical components and module components in a cabinet. However, during use, the power transformer condition inspection and maintenance intelligent management device usually simply opens heat dissipation holes and installs dust filters to dissipate heat and cool the interior. The heat dissipation effect of this method is not ideal, and the heat dissipation efficiency is low, which causes the power transformer condition inspection and maintenance intelligent management device to be easily damaged by high temperature or unstable operation. Moreover, when used for a long time, the dust filter is prone to adhere to a lot of dust and impurities, which easily causes the filter holes on the dust filter to be blocked, requiring staff to manually operate and clean the dust filter, which not only affects the heat dissipation effect of the main body of the intelligent management device, but also increases the workload and working time of the staff. To this end, we propose an power transformer condition inspection and maintenance intelligent management device to solve the above problems.

The inside of the management device body 1 can quickly and effectively dissipate heat and cool down, and the heat dissipation efficiency is high, so as to ensure the stable operation and use of the intelligent management device body 1. In the process of dissipating heat and cooling down the inside of the intelligent management device body 1, the left rotating shaft 8 is used to drive the brush rod 12 and the bristles 13 to rotate, so as to clean the surface of the air inlet filter 5, and to clean the dust and impurities adhering to the air inlet filter 5, thereby realizing the function of automatic cleaning of the surface of the air inlet filter 5, and avoiding dust from adhering to the air inlet filter 5 for a long time, causing the filter holes to be blocked and affecting the heat dissipation effect of the intelligent management device body 1. There is no need to manually clean the air inlet filter 5, thereby reducing the workload and working time of the staff.
