Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power equipment, in particular to an anti-interference protection device and method of power grid. BACKGROUND

[0002] In the power grid system, the anti-interference protection box is the key equipment to ensure the normal operation of the equipment. The anti-interference protection box mainly uses materials with high conductivity and high magnetic permeability to realize the anti-interference function. Its principle is based on electromagnetic shielding theory. When external electromagnetic waves radiate to the protection box, the metal material (such as copper, aluminum or its alloy) used by the box will reflect and absorb electromagnetic waves by using its own free electrons. On the one hand, the free electrons on the surface of the metal will produce induced current under the action of the electric field of the electromagnetic wave, and the induced current will form an electromagnetic field opposite to the external electromagnetic field, thereby realizing the reflection of the electromagnetic wave. On the other hand, part of the electromagnetic wave will be absorbed after entering the metal material due to the high magnetic permeability and resistance characteristics of the material, and the energy of the electromagnetic wave will be converted into heat energy, thereby achieving the purpose of weakening or eliminating electromagnetic interference. However, in the design of the traditional anti-interference protection box, much attention is paid to the realization of this electromagnetic shielding function, but there are many deficiencies in ventilation and dust prevention.

[0003] In order to realize the heat dissipation of the internal equipment, the traditional anti-interference protection box usually sets a ventilation hole. However, this simple ventilation hole design has obvious defects in actual application. Since the ventilation hole is directly in contact with the external air, when the external air enters the inside of the protection box, dust will enter without any hindrance. Long-term accumulation will not only affect the heat dissipation efficiency of the equipment in the box, but also may cause equipment short circuit and other faults, reducing the reliability and service life of the equipment. Therefore, an anti-interference protection device and method of power grid are needed to solve the above problems. SUMMARY
