the beneficial effects of the invention are shown in the following aspects:

1. and optimizing the performance of the case. Besides the basic dust removal function and the heat dissipation function, the case is optimally designed in multiple aspects, so that the case has higher practicability. The optimization design is mainly embodied as follows:

1) good sealing performance. The cable interface of the case is prefabricated in a standard way, and the cable in the case is connected with the outside through the interface, so that the situation that the cable directly enters and exits from the hole of the case to leave a redundant gap is avoided; the air inlet is provided with a fresh air purifier, the air outlet is provided with a cooling fan, especially when an auxiliary air port fan does not work at ordinary times, in order to prevent dust outside the case from entering the case from the air port, the cooling fan with the function of automatically closing the air port by a fan blade is adopted, the air port is automatically closed by the fan blade when the fan does not work, so that the inside of the case and the outside are in relatively independent space, and the air outlet is additionally held by a filter screen; and cross support bars are adopted on the inner side surfaces of the box body, so that the case is prevented from deforming and sinking to increase the gap of the side door, and the case is ensured to have good sealing property. For the host machine needing protection, the host machine can be taken down only as a surface of a closed shell and directly placed in a case for operation, so that ventilation and heat dissipation of equipment are facilitated;

2) good spatial layout. 2 main machines are erected and installed by a support (3 cm from the bottom surface of the case) and a reasonable horizontal distance is kept between the two main machines, so that the main machines have good ventilation channels in the case; various cables of auxiliary equipment in the case are uniformly wired and are connected out through a prefabricated interface on the case body, so that the ventilation of a ventilation channel is facilitated, and the negative pressure ventilation and cooling effect of the case is effectively improved;

3) the convenience of use is maintained. The front side and the right side of the case adopt a movable door form, so that the case is convenient to install, maintain and use, and lock catch configuration is added for better sealing; the inner side of the top surface of the case is provided with a track, so that the proper temperature measuring position of the temperature sensing detecting rod can be conveniently adjusted; a transparent closed organic glass monitoring window is arranged on the front side surface of the case, so that the environment temperature in the case can be visually checked;

4) the application range is expandable. The case used for the monitoring machine in the monitoring table is only required to be slightly in a proper flat design, and the connecting lug plate firmware is additionally arranged at the front ends of the two sides of the case, so that the case is conveniently installed on the secondary screen cabinet, and high-quality service is provided for equipment such as a network switch, an encryption device and a firewall.

2. The case is provided with a temperature monitoring intelligent alarm. The case is designed with temperature abnormal signal output when the temperature in the case is higher than the normal temperature, and the temperature alarm signal is connected to an automatic monitoring system, so that the temperature of the operating environment of the equipment can be monitored in real time for an unattended transformer substation, and early warning is facilitated.

3. The case is environment-friendly and energy-saving. Besides the main air port fan which normally works, the heat dissipation air port fan of the case also comprises 2 fans of auxiliary air ports on the left side surface and the right side surface of the case body, and when the temperature of the case is not high at ordinary times, the two fans are in a stop state, because the air quantity of the main heat dissipation air port is larger than the air quantity of an air inlet of the fresh air purifier, the whole case still keeps negative pressure ventilation and can normally work. Once the temperature in the machine box is higher than the temperature setting value, the auxiliary air opening fan is started to work, so that unnecessary energy consumption caused by the fact that the auxiliary air opening fan still works when the temperature in the machine box is not high is avoided.
