Some electrical parameters are adjusted to prompt or send signals for deviations from the normal working state, which are often used in various power generation, distribution and substations.

There are multiple devices inside the control cabinet, and a large amount of heat will be generated during the use of the equipment. The accumulation of heat inside the control cabinet for a long time will affect the normal operation of each device inside the control cabinet, and even lead to serious short circuits in the control cabinet or damage to the equipment. The problem is, in order to remove the heat inside the control cabinet in time, the common method is to open a vent on the surface of the control cabinet, and then use the fan to accelerate the air flow inside the control cabinet to achieve the effect of quickly exhausting heat, but due to the position of the fan in the control cabinet. The ventilation and cooling effect of the position between the fan and the ventilation port close to the fan is much better than that of other positions inside the control cabinet, resulting in poor ventilation and cooling effect in other positions of the control cabinet. In order to prevent external dust and impurities Enter the inside of the control cabinet, and set the filter screen at the air vent. The filter screen needs to be cleaned for long-term use, but the common filter screen is directly fixed on the surface of the control cabinet, which is inconvenient to disassemble and clean.
