The invention discloses a full-sealed type series current transformer which comprises a transformer body, a base, a primary winding and secondary windings, wherein the base is in a U shape, the transformer body is fixedly arranged above the base, the primary winding is arranged on one side of the base, a plurality of groups of the secondary windings are arranged under one side of the transformer body, and an asbestos protection layer is arranged on the surface of the transformer body. The full-sealed type series current transformer disclosed by the invention has the beneficial effects that bymeans of additionally arranging the asbestos protection layer on the outer side of the transformer body, cold resistance of equipment is improved, and external impact can be effectively prevented at the same time; an ultrasonic cleaner can emit ultrasonic wave to automatically clean dust on the surface of the transformer body, dust accumulation is prevented, and a phenomenon of discharge along a dielectric surface is eliminated; a coloration silica gel pad is additionally arranged at the bottom of the base, so that moist air at the equipment installation part can be effectively removed; furthermore, anti-seismic property of equipment can be improved.
Description
technical field [0001] The invention relates to the field of transformers and AC transformers, in particular to a fully enclosed series of current transformers. Background technique [0002] A current transformer is an instrument that converts a large current on the primary side into a small current on the secondary side for measurement based on the principle of electromagnetic induction. A current transformer consists of a closed core and windings. Its primary side winding has few turns and is connected in series with the current line to be measured. Therefore, it often has all the current of the line flowing, and the number of turns of the secondary side winding is relatively large. It is connected in series with the measuring instrument and the protection circuit. When the current transformer is working, its secondary side circuit is always closed, so the measurement The impedance of the series coil of the instrument and the protection circuit is very small, and the wor...
