The invention discloses a guide rail type closed-loop single-phase miniature
current transformer. The
current transformer comprises a bottom plate, a mutual
inductor is arranged above the bottom plate, a lifting structure is arranged above the bottom plate, the lifting structure comprises a first sliding block, a first shell, a first vertical plate, a vertical rod, a first spring, a curved rod, a round block, a second vertical plate, a first
threaded rod and a secondshell, the bottom of the first shell is fixedly connected with the top of the bottom plate, and a vertical rod is in clearance fit with the inner wall of one side of the top of the first shell. According to the guide rail type closed-loop single-phase miniature
current transformer, through cooperation of the
transformer, a bottom plate, a long plate, a third shell, a rod body, a first sliding rod and the lifting structure, a first
threaded rod is rotated, the first
threaded rod drives a first sliding block to move downwards, the first sliding block drives a round block to move downwards, the round block drives a bent lever to rotate, the bent lever drives the second vertical plate to move upwards, and the second vertical plate drives the
transformer to move upwards, so that a worker can conveniently adjust the vertical height of the
transformer, the application range is wide, and practicability is high.
