Method for increasing creepage distance and electrical gap of OCT equipment

The invention relates to a method for increasing creepage distance and electric gap of OCT equipment. The method is characterized in that on the one hand, the pull-down surfaces of an upper plastic shell and a lower plastic shell are changed from flat openings to vertical meshing structures in order to increase the creepage distance; on the other hand, the distance between a sensitive circuit andeach shell is increased, the electrical gap is increased, and the situation that during 15-kV air discharging, high voltage penetrates through cracks of the plastic shells and enters the inside of theequipment to break down the sensitive circuit is avoided. According to the method, by synchronously increasing the distance between the sensitive circuit and each shell and increasing the high-voltage creepage distance to reduce the influence on an internal circuit, the antistatic performance of the equipment is improved. The method has the advantages of being simple, reliable, high in operability and low in cost; the imp
