Abstract
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.
Description
technical field [0001] The invention relates to the technical field of transformers, in particular to a rail-type closed-loop single-phase miniature current transformer. Background technique [0002] Transformer, also known as instrument transformer, is a general term for current transformer and voltage transformer. It can change high voltage into low voltage and large current into small current for measuring or protection system. Its function is mainly to convert high voltage or large current into standard low voltage (100V) or standard small current (5A) in proportion or 1A, both refer to the rated value), in order to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. At the same time, the transformer can also be used to isolate the high-voltage system to ensure the safety of people and equipment. [0003] The guide-rail type closed-loop single-phase miniature current transformer in the prior ar...
