Title:
UNIT-TYPE CURRENT TRANSFORMER
Document Type and Number:
WIPO Patent Application WO/2020/244144
Kind Code:
A1
Abstract:
Disclosed is a unit-type current transformer, comprising a plurality of unit members, wherein each of the unit members comprises an outer shell (1), a magnetic core (2), a coil (3) and an electrode (4); the electrode (4) comprises a positive electrode (41) and a negative electrode (42); the coil (3) is wound around the magnetic core (2); one end of the coil (3) is connected to the positive electrode (41), and the other end thereof is connected to the negative electrode (42); the plurality of unit members are connected end to end to form a ring; the outer shells (1) are detachably connected to each other; the magnetic cores (2), the positive electrodes (41) and the negative electrodes (42) are respectively in contact connection with each other; and a positive connector and a negative connector respectively connected to the positive electrode (41) and the negative electrode (42) are led out from one unit member. The current transformer takes the form of a unit member. Various unit members are detachably connected to or in contact connection with each other, and the coils (3) are connected in parallel, such that the overall length and the shape of the unit members can be randomly changed, but the change ratio does not change; therefore, the current transformer is strong in adaptability and meets the specification requirement for the stable change ratio; in addition, the coils (3) are connected in parallel, thereby further reducing the problem of inconsistencies during a coil manufacturing process, and therefore, the detection result is more stable.
