Description
Technical Field
The utility model belongs to the technical field of the reactor, especially, relate to a shunt reactor yoke and reactor.
Background
For a three-phase parallel reactor arranged in a shape like a Chinese character 'pin', an iron yoke is generally coiled by an electrical steel belt, the electrical steel belt is very thin, the whole iron yoke coiled by the electrical steel belt is equivalent to an inductance coil with thousands of turns, zero-sequence magnetic flux passes through the iron yoke under the operating condition of three-phase unbalance, and large induced potential can be generated among sheets of the iron yoke, so that the product is damaged. Therefore, it is an urgent problem to improve the reliability of the operation of the parallel reactor by eliminating the induced potential between the pieces of the iron yoke by technical means.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a technical scheme of shunt reactor yoke and reactor to solve above-mentioned technical problem.
The utility model discloses a first aspect discloses a shunt reactor yoke, include: the fan-shaped iron yoke lamination, the first insulating material and the second insulating material; the first insulating material is used for insulating and dividing the three fan-shaped iron yoke laminations to form a circular ring, and the second insulating material is used for integrally supporting the hollow part of the circular ring.
In some embodiments, the first insulating material is three epoxy insulating boards.
In some embodiments, the first insulating material is an epoxy insulating tube.
In some embodiments, the fan-shaped yoke laminations, epoxy insulation plates, and epoxy insulation tubes are integrally cast using a vacuum epoxy casting process to produce an epoxy cast layer.
In some embodiments, each of the fan-shaped yoke laminations is formed by a radial stack of incrementally sheared rectangular electrical steel strips.
The utility model discloses a reactor in the second aspect, including any one of the first aspect shunt reactor yoke.
It is thus clear that, the utility model provides a scheme, rational in infrastructure simple, make simple to operate, mechanical strength is good, has solved the three-phase shunt reactor that article style of calligraphy was arranged when three-phase unbalanced operation, and zero sequence magnetic flux induced potential causes the problem of indisputable yoke trouble.
