Background technology
Current transformer is common alternating current detection sensor or energy converter in electric power, electronics industry, is mainly tied
Structure is the coiling multi-turn electromagnetic coil in annular or square soft magnetic core, and detected conducting wire passes through mutual inductor centre bore, when
When detected conducting wire has the alternating current to flow through, the size for the electric current that multi-turn electromagnetic coil is flowed through according to detected conducting wire senses
Go out the induced electromotive force of corresponding size.Open-close type current transformer is on the basis of above-mentioned principle, is led for convenience of what is be detected
Line passes through the centre bore of mutual inductor, and the closed loop configuration of current transformer is divided into 2 half part main bodys as open architecture；
When installing and using, first detected conducting wire is surrounded at center with 2 half part main bodys, then passes through mechanical connecting structure respectively
It is mechanically connected, is electrically connected by connecting structure for electrical equipment, closed up so as to dock as a complete Current Mutual Inductance
Device.
Traditional folding current transformer sets one to turn using one end of the joint face in 2 half part main bodys mostly
Axis, in the other end screw or hasp connection of joint face, and in the conducting wire connection two more than piece two cores of this one end of shaft
Half part main body realizes electrical connection, and 2 half part main bodys can not be kept completely separate.Since shaft end does not have elastic construction, pressing
When 2 half part body interiors magnetic core can not realize fit closely cause magnetic circuit reluctance increase and leakage field it is serious, until making performance tight
Decline again；It is fitted closely if used in the internal method for setting elasticated topsheet to solve the problems, such as that magnetic core can not be realized, then coil
Main body must can move, and interiors of products can not also carry out injecting glue sealing, and inner lead is also easily broken off, greatly influences
Reliability and service life.
Also have some current transformers, with a metal anchor ear 2 half part main body obvolvents together, with two cores
Above conducting wire realizes electrical connection, and 2 half part main bodys can not be kept completely separate.This current transformer installation ratio
More difficult, insulation performance is poor, and metal anchor ear also easily causes electrical safety accident.Also some mutual-inserting type current transformers, two
