Currently, the iron core of LXK series zero sequence current mutual inductors uses ring current iron core, in the process of cutting annular core In be easily broken, cause its rejection rate to remain high always.In addition, fixing cut-out section using steel band, section is caused to combine not Closely, error is excessive, position inaccurate, and difficulty of processing is big.
Utility model content
For various deficiencies of the prior art, to solve the above-mentioned problems, it is proposed that a kind of to use semicircular arc-shaped notch iron The notch LXK zero sequence current mutual inductors of core.
To achieve the above object, the utility model provides the following technical solutions:
A kind of LXK zero sequence current mutual inductors, including iron core and be coated on iron core periphery pour building body, the iron core includes The identical notch iron core of 2 block structures, the notch iron core is semicircular arc, and 2 pieces of notch iron cores are oppositely arranged to be formed in a ring Iron core, the building body of pouring includes that structure identical first pours building body and second and pours building body, and is both coated on notch iron core Periphery, described first, which pours building body and second, pours building body and is bolted, and the described second lower section for pouring building body is equipped with solid with it Pedestal even.
Further, the described first both ends for pouring building body are equipped with the first engaging lug, and the described second both ends for pouring building body are equipped with the Two engaging lugs, first engaging lug are oppositely arranged with the second engaging lug.
Further, it is embedded with inside second engaging lug and is matched with bolt through there is bolt on first engaging lug Nut.
Further, it is arranged with mutual inductor coil on the notch iron core, on first engaging lug and the second engaging lug Equipped with the outlet terminal connected for mutual inductor coil.
Further, the outlet terminal positioned at iron core side is connected by connection sheet, is located at the outlet terminal of the iron core other side Independently of each other.
Further, the pedestal is equipped with 2, and 2 pedestals are located at the second both sides for pouring building body.
The utility model has the beneficial effects that:
Traditional ring current iron core is substituted using semicircular arc-shaped notch iron core, meanwhile, using bolt replace steel band into Row is fixed, and is improved the bonding tightness of notch core section, is increased contact area, and product error is reduced, and reduces vortex Loss improves integral product performance.The monolithic weight of notch iron core is small, reduces winding operation difficulty.
