Distribution box needs improvement

With the rapid development of China's power distribution equipment technology, everyone has higher and higher requirements for power distribution equipment. The distribution box is an important part of the distribution equipment, and the transformation of the distribution box is also very important. Then the distribution box needs to be improved, what are the methods? The following Xiaobian to specifically introduce, I hope to help everyone.

Distribution box needs improvement

1, can increase the size of the box, increase the electrical safety distance between the parts.

2. Chemical paints with thermal insulation properties can be sprayed in the cabinet to reduce radiation and reduce the temperature inside the cabinet. At the same time, the interior and exterior of the cabinet must be coated with a layer of rust-proof and anti-corrosion paints to prevent premature failure.

3, in the purchase of electrical appliances, good low-voltage electrical selection and purchase acceptance should be closed, select a good quality AC contactor, select the wire, in addition to select the quality of the wire, but also check whether there is damage.

4. As the distribution box generates a lot of heat during operation, if the cooling capacity of the equipment is not strong, it will affect the normal operation of the equipment. Therefore, if the space of the cabinet is large, the temperature control relay and the exhaust fan can be installed inside so that the heat in the cabinet can be eliminated in time.

Method for preventing corrosion of distribution box casing

Because of its special metallurgical structure and surface passivation film, the distribution box makes it difficult to corrode with chemical reaction with the medium under normal circumstances, but it cannot be corroded under any conditions. In the presence of corrosive media and inducing agents (such as scratches, splashes, slags, etc.), the distribution box can also corrode with the slow chemical and electrochemical reactions of the corrosive media, and the corrosion rate is fairly rapid under certain conditions. Corrosion phenomena occur, especially pitting and crevice corrosion.
