Technical field
The utility model relates to the reactor in a kind of power industry, specifically relates to a kind of magnetic screen dry-type half iron core shunt reactor.
Background technology
Current China power grid construction, enlarging and transformation deepen continuously, although traditional dry type hollow shunt reactor is widely used, but also there is obvious defect, particularly around reactor, there is serious flux leakage, small product size is large, and loss strengthens, noise is obvious, low-power affects the quality of power supply, and leakage field seriously can have an impact to ambient electron instrument, and electromagnetic pollution is serious.
Summary of the invention
In order to solve the problem, the utility model provides on the basis of common dry type hollow shunt reactor that a kind of leakage field is few, Short Circuit withstand advantage, loss is low, volume is little magnetic screen dry-type half iron core shunt reactor.
The utility model is achieved through the following technical solutions: a kind of magnetic screen dry-type half iron core shunt reactor, comprise the shunt reactor body supported by post insulator, reactor body comprises interior iron core, outer iron core and reactor line bag, described interior iron core is arranged to the hollow interior that tubular is placed on reactor line bag, interior iron core is made up of three groups of discrete circular arc iron cores, often organize between circular arc iron core and epoxy plate is set, described outer iron core is also arranged to the outside that tubular is placed on reactor line bag, outer iron core is made up of two groups of discrete semicircle iron cores, epoxy plate is provided with between two groups of semicircle iron cores, the both ends of the surface of interior iron core and outer iron core are provided with insulating barrier, polyester glass fiber leading-drawing rod is provided with between interior iron core and reactor line bag and between outer iron core and reactor line bag.
In such scheme, described interior iron core and outer iron core adopt the silicon steel sheet of high magnetic conduction effect to make, and the density of iron core is 0.8T.
A kind of magnetic screen dry-type half iron core shunt reactor of the utility model compared with prior art, has following beneficial effect:
1, utilize the magnetic permeability of iron core to be greater than the characteristic of air, part changes magnetic flux path, thus reduces the aerial divergent state of magnetic flux.
2, when reality is impacted in the face of short-circuit electromotive force, good impact resistance is shown.
3, under equivalent capability, coil diameter significantly reduces, and conductor length greatly reduces, and loss reduces 50.6%, for a large amount of electric energy is saved in electric power system.
4 compare with dry type hollow shunt reactor, and floor space reduces 34.4%, can meet power transmission and transformation place installing space being had to requirement.
