The invention relates to the technical field of cases, and discloses an anti-static case of electrical equipment and an application method thereof. The anti-static case comprises a composite baffle plate, wherein the upper part and the lower part of the composite baffle plate are fixedly connected with protruding blocks, the bottom of the composite baffle plate is connected with a bottom plate ina clamped mode, the top of the bottom plate is provided with sliding grooves and notches, limiting blocks respectively penetrate through the inner sides of the sliding grooves, a conducting strip is fixedly connected to the middle of the top of the bottom plate, two sides of the conducting strip are fixedly connected with conducting rods, the bottom of the conducting strip is fixedly connected with a grounding wire, the air is ionized by an ion fan, the ion fan generates positive and negative ions, and the positive ions and the negative ions quickly move downwards under the action of a flow guide groove, so that the positive ions and the negative ions reach a high-electrostatic structure in the electrical equipment, and the static electricity of the structures can be neutralized and counteracted. The static electricity can be neutralized and counteracted on the one hand and be conducted and eliminated on the other hand by combining the anti-static plate, the conducting rods and the conducting strip, and potential safety hazards are thoroughly eliminated.
