The utility model provides a sealing structure of a
current transformer, and relates to the technical field of current transformers. According to the
current transformer, the first rubber pad at the bottom of the upper sealing shell is attached to the second rubber pad at the top of the lower sealing shell, a primary sealing defense line is formed, external
water vapor, dust and other impurities are prevented from invading from the joint of the upper sealing shell and the lower sealing shell, the first
rubber ring in the fixing base tightly surrounds the pins of the
current transformer, sealing is further strengthened, and the sealing effect is improved. A second
rubber ring at the top of the fixed seat blocks impurities permeating along the gap of the fixed seat, and when the current
transformer generates slight displacement due to environment temperature change or internal operation, a ball on the fixed seat can reduce
friction force, so that the sealing
assembly can flexibly adapt to the current
transformer, and the service life of the current
transformer is prolonged. And the rubber pads and the rubber rings are always kept in a good sealing and attaching state, so that the internal sealing performance of the current transformer is comprehensively guaranteed, and the stable operation of the current transformer is maintained.
