Nowadays, the aviation connector should be very extensive, and there will be a variety of problems in use, such as how to waterproof the aviation plug? This is a problem that bothers a lot of people.

Aviation plug box in substation is an important link between outdoor electrical equipment and indoor measurement and control, protection, communication and other equipment, which is generally installed beside the equipment. When the air is humid, especially in rainy season, the outdoor switch aviation plug box is wet and condensation water, which is easy to cause the fuse to fuse, even damage the equipment, seriously threatening the safe operation of the power grid. The damp of aviation plug box will cause the screw and connecting piece of terminal strip to rust, and make the secondary terminal not in good contact, which will also make the current circuit terminal hot or even open circuit, resulting in protection failure or misoperation, causing accidents. If the voltage, switch and temperature signal terminals of the transformer are not in good contact, the aviation plug will cause abnormal operation of the measurement and control and protection devices, and send signals by mistake, which will cause the operators to misjudge and make wrong analysis.

It is of great significance to find out and analyze the causes of air connector box damp and take measures to prevent accidents. The aviation plug box in substation seems to be a simple accessory equipment, and its management and maintenance are often ignored. However, the current situation is that the terminals of a considerable part of aviation plug boxes in some substations are severely rusted, which seriously affects the safe operation of the equipment. Therefore, it is necessary to strengthen the type selection, construction process management and operation maintenance of aviation plug box.

In the design and selection of aviation plug box for switch in substation, the moisture-proof, rain proof, high-temperature and low-temperature resistance of outdoor aviation plug box should be fully considered, and the convenience of maintenance and operation should be reasonably considered. The switch aviation plug box is completely separated from the cable trench. Special ventilation holes are installed on both sides of the switch box, which can form convective wind, play a cooling role, and ensure that the internal components of the box are dry. However, it is necessary to take measures to prevent rain and small animals.

With the increasing of signal types and the increasingly fierce competition, in order to accept the function of its own products by the market, in addition to considering the above factors, it is necessary to have a comprehensive test on the electrical function of aviation plug.

Smart aviation precision connector, with waterproof function of aviation plug series: T, K, W, F series, commonly used in outdoor electrical box, multi-core number optional, can solve power supply, signal and other purposes.
