Description
Technical field
the utility model belongs to field of electrical equipment, is specifically related to a kind of low noise reactor body structure used for rail vehicle.
Background technology
reactor used for rail vehicle is widely used in high speed railway car, in vehicle secondary power system in inverter output loop, suppress the harmful effect that in inverter output current, higher harmonic component is brought, for vehicle boarded load provides electric energy, for saving vehicle interior space, reactor often directly hangs on under-vehicle.In order to ensure the comfortableness of rail vehicle, products noise will strictly control.
as depicted in figs. 1 and 2, conventional reactor machine body structure comprises the lower yoke 30, iron core column 20 and the upper yoke 10 that are fixedly connected sequentially from the bottom up, described iron core column 20 outer race is provided with coil 40, between iron core column 20 and coil 40, there is space, stretching is carried out with fagging 50, then overall dipping lacquer solidification process between coil 40 and iron core column 20.Conventional reactor noise is mainly because the silicon steel sheet magnetostriction forming iron core column 20 causes vibration to produce.In conventional reactor machine body structure, because coil 40 and iron core column 20 are rigidly connected by fagging 50, iron core column 20 is vibrated directly band moving winding 40 and is vibrated, and noise directly can be dispersed out by solid conduction, causes whole reactor noise larger.
Utility model content
for the defect of prior art, the technical problems to be solved in the utility model is to provide the simple low noise of a kind of structure reactor body structure used for rail vehicle.
in order to solve the problems of the technologies described above, a kind of technical scheme that the utility model adopts is: a kind of low noise reactor body structure used for rail vehicle, comprise the lower yoke, iron core column and the upper yoke that are fixedly connected sequentially from the bottom up, the outer surface of described upper yoke and lower yoke is fixedly equiped with yoke clip piece, described iron core column outer race is provided with coil, has space between iron core column and coil.Described coil is placed on the yoke clip piece of lower yoke, and the yoke clip piece of described upper yoke is fixedly installed hold down gag, and coil can be pressed abd fixed on the yoke clip piece of lower yoke by described hold down gag.
preferably, described hold down gag can be pressed on compression degree on the yoke clip piece of lower yoke by regulating winding.
concrete, described hold down gag have can stretch hold out against part, described in hold out against part and contact with the upper surface pressure of coil.
concrete further, described hold down gag comprises the nut be fixed on the yoke clip piece of upper yoke and the adjustment screw be connected with nut screw connection, described adjustment screw contacts with the upper surface pressure of coil, regulate rotate adjustment screw can the compression degree of upper surface of regulating and controlling screw and coil.
preferably, the upper surface of described coil is also provided with elastic cushion block, described adjustment screw contacts with elastic cushion block pressure and is pressed abd fixed on the yoke clip piece of lower yoke by coil.
preferably, described elastic cushion block is elastic block rubber.
preferably, described hold down gag has multiple and along upper yoke surrounding and distributes.
the upper and lower noun of locality described in the utility model is undefined at reactor normal operating condition.
scope of the present utility model, is not limited to the technical scheme of the particular combination of above-mentioned technical characteristic, also should contain other technical scheme of being carried out combination in any by above-mentioned technical characteristic or its equivalent feature and being formed simultaneously.The technical characteristic that such as, disclosed in above-mentioned feature and the application (but being not limited to) has similar functions is replaced mutually and the technical scheme etc. formed.
because technique scheme is used, the utility model compared with prior art has following advantages: coil is pressed on the yoke clip piece of lower yoke by hold down gag by the utility model, contactless between iron core column and coil, without rigid support.The vibration that iron core column can be made to produce can not be directly passed to coil, decreases the generation of noise.Install elastic cushion block between hold down gag and coil, then the yoke clip piece vibration that the vibration that can reduce iron core column drives conducts to the vibration of coil.The noise that the utility model avoids iron core column vibration is directly passed to surrounding environment by coil, substantially reduces the overall noise of reactor.
