Abstract
The utility model discloses an oversized combined magnetic ring for signal detection of a power transformer, which relates to the field of signal detection of power equipment. The oversized combined magnetic ring for signal detection of the power transformer comprises a magnetic ring body (1) bonded by a plurality of magnetic bars (2) in same specification. According to the oversized combined magnetic ring for signal detection of the power transformer, the production difficulty can be reduced, the production efficiency can be improved, and the cost can be lowered.
Description
Technical field:
The utility model relates to power equipment input field, relates in particular to a kind of combined magnet ring of super large that is used for the power transformer input.
Background technology:
The power transformer signal detection apparatus is and the supporting use of power transformer will the whole circle of power transformer be lived during detection; Because power transformer equipment is bigger, so the size of its signal detection apparatus also must be big, this magnet size that just requires to be applied in the checkout equipment is also bigger.Common production method is directly according to the size of magnet mould customized, passes through special equipment moulding and sintering then, produces required magnet.Because magnet size is very big, customer demand is seldom produced like this and had two defectives: one, in moulding and these two technical processs of sintering, general device is difficult to produce, and use special equipment, and also needs are customized for equipment in case of necessity; And cracking, fracture and distortion appear in magnet extremely easily, cause the qualification rate of magnet too low.Two, owing to need mould customized and equipment, cause production cost too high; And in process of production, product percent of pass is too low, even can't produce qualified magnet, has also improved production cost greatly.
The utility model content:
The purpose of the utility model provides a kind of combined magnet ring of super large that is used for the power transformer input, and it can reduce the production difficulty, enhances productivity, and reduces cost.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises magnet ring body 1, and described magnet ring body 1 is by identical magnetic stripe 2 bonding the forming of several specifications.
Described magnet ring body 1 is for being cut in round regular polygon outward.
Described magnetic stripe 2 is the soft magnetic ferrite magnetic stripe.
The utility model is divided into each undersized magnetic stripe 2 through bonding method with large-sized magnet, and each magnetic stripe 2 is ground processing according to certain angle; As requested size is made a frock then, and the magnetic stripe 2 that mill is good is put in the frock one by one, with epoxide-resin glue it is bonded together; Solidify down at 120 ℃, saved the expense of mould customized and equipment, and in production process; Do not need specialized apparatus to go to produce; Reduce the production difficulty greatly, improved production efficiency, significantly reduced production cost.
The utility model can reduce the production difficulty, enhances productivity, and reduces cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1, this embodiment adopts following technical scheme: it comprises magnet ring body 1, and described magnet ring body 1 is by several magnetic stripe 2 bonding forming.
Described magnet ring body 1 is for being cut in round regular polygon outward.
Described magnetic stripe 2 is the soft magnetic ferrite magnetic stripe.
This embodiment is divided into each undersized magnetic stripe 2 through bonding method with large-sized magnet, and each magnetic stripe 2 is ground processing according to certain angle; As requested size is made a frock then, and the magnetic stripe 2 that mill is good is put in the frock one by one, with epoxide-resin glue it is bonded together; Solidify down at 120 ℃, saved the expense of mould customized and equipment, and in production process; Do not need specialized apparatus to go to produce; Reduce the production difficulty greatly, improved production efficiency, significantly reduced production cost.
This embodiment can reduce the production difficulty, enhances productivity, and reduces cost.
