Background technology:
In existing the power transformer, the modes of emplacement of special transformer of iron formula core construction all adopt vertical type, and promptly core limb is perpendicular to ground, and the cross section of its core limb is rectangle or is external in round stairstepping.Because the coil of high-power special transformer is a cake formula structure, special transformer adopts vertical type to make the medium of horizontal run between the coil cake be not easy heat is taken out of by convection type, and radiating effect is poor.
The core limb section is that to be external in round stairstepping be traditional structure, and most transformers all adopt it.It is circular that this structure makes coil, and coiling is easy, and the ability that circular coil intensity height bears sudden short circuit is strong; The shortest electromagnetic wire of relatively economizing of circular coil line length when core section is identical.Shortcoming is that circular unshakable in one's determination sheet specification is many, and it is many to cut repeatedly man-hour.When window size was identical, iron circuit was the longest in this core construction, thereby silicon steel sheet consumes maximum.Big as the horizontal type transformer floor space.
Its coil of the core construction of square-section also is a rectangle.The shortcoming of square coil is that technique for coiling is relatively poor.Even since the elasticity of electromagnetic wire coiling core be rectangle but the coil of coiling moulding all is oval-shaped, must after shaping, could use.The length of electromagnetic wire will additionally increase like this, and the coil actual size all can all have bigger difference with design load with design value difference easily big relevant electromagnetic parameter such as conductor length, weight, D.C. resistance, load loss and impedance.The ability that square coil bears sudden short circuit a little less than; The longest electromagnetic wire consumption of rectangle wire turn length was maximum when core section was identical.But the sheet specification of rectangular core is minimum, and it is few to cut repeatedly man-hour.When window size was identical, iron circuit was the shortest in this core construction, thereby the silicon steel sheet consumes least, and is little as the horizontal type transformer floor space.
The utility model content:
The purpose of this utility model provides that a kind of perfect heat-dissipating temperature rise is low, and floor space is little, and cost is low, and is easy to manufacture, crosses and cuts strong, the safe in utilization horizontal type transformer of ability.
The utility model is achieved in that
The utility model horizontal type transformer, the opposite flank of each core limb 1 is connected with insulation arm-tie 5, insulation arm-tie 5 is connected with folder 9, the axial horizontal arrangement of core limb, a plurality of high and low pressure windings that are in series are arranged on the iron core column, the high and low pressure winding is a disc coil, and the insulation arm-tie 5 of iron core column downside is connected with supporting bracket 7.
The lower end of supporting bracket 7 is connected with pad pin 8, and the insulation arm-tie 5 of core limb downside is connected with strutting piece 6, and the lower end of strutting piece 6 is connected with pad pin 8.
The cross section of core limb and disc coil is oval, the axis of three core limbs in parallel at grade, the axis spacing of perhaps adjacent two core limbs equates.
The axis spacing of adjacent two core limbs equates that each is connected adjacent two core limbs with an insulation arm-tie 5, and adjacent insulation arm-tie connects by iron yoke screw rod 14.
The utility model horizontal type transformer, the opposite face of each core limb 1 is connected with folder 9 with insulation arm-tie 5, and the axial horizontal arrangement of core limb has a plurality of high and low pressure windings that are in series on the iron core column, the high and low pressure winding is a disc coil, and socketing below the iron core column 5 is connected with supporting bracket 7.
The lower end of supporting bracket 7 is connected with pad pin 8, and the insulation arm-tie 5 of core limb downside is connected with strutting piece 6, and the lower end of strutting piece 6 is connected with pad pin 8.
The cross section of core limb and disc coil is oval, the axis of three core limbs in parallel at grade, the axis spacing of perhaps adjacent two core limbs equates.
The axis spacing of adjacent two core limbs equates that each is connected adjacent two core limbs with an insulation arm-tie 5, and adjacent insulation arm-tie connects by iron yoke screw rod 14.
The transformer coil of horizontal placement is a cake formula structure, and horizontal air flue has originally become uptake ventilator, and radiating effect improves greatly, and this is not only the consumption that reduces electromagnetic wire, reduces manufacturing cost.Can also reduce the height of transformer greatly.If use horizontal phase shifting transformer in high-voltage high-power frequency transformator, the space that transformer case top is reserved is enough to install isolation switch (its high pressure isolation switch of common high-pressure frequency-conversion apparatus is all dressed up a cupboard separately).So just saved the floor space of an isolation switch cabinet.This does the frequency conversion transformation to those plans but user's particularly suitable that floor space is restricted again.
The cross section of the leg in the utility model is adopted oval-shaped, and its coil also is the oval shortcoming that has overcome square coil coiling difficult forming, has kept that the square-section iron circuit is short, the few advantage of consumption of silicon steel sheet.Comprehensive pluses and minuses are between circle and rectangular core.
It is unshakable in one's determination relatively unshakable in one's determination with planar structure that core limb is arranged as leg-of-mutton stereochemical structure.
It is the most frequently used core construction pattern because its laminate patch technology is simple that core limb is arranged in one plane planar structure unshakable in one's determination, but the unequal A of its three-phase magnetic circuit, C phase magnetic circuit be greater than the B phase, so A, C phase no-load current are also greater than the B phase.
It is unshakable in one's determination because its laminate patch complex process must be used roll-over table unshakable in one's determination to iron yoke laminate patch the time that core limb is arranged stereochemical structure triangular in shape, thereby seldom adopt.But its three-phase magnetic circuit equates that the three-phase no-load current equates that this is the advantage of its uniqueness.Especially adopt this horizontal type transformer that designs unshakable in one's determination to match, so still will adopt this structure because of the cabin profile of its unique appearance and wind-powered electricity generation.In recent years, because the development of volume technology unshakable in one's determination, it is unshakable in one's determination the three-phase stereo volume to have occurred.Purchase this iron core and special-purpose coil winding machine, just much more simply the transformer of producing the wind-powered electricity generation special use.
In sum, the horizontal type transformer in the utility model has perfect heat-dissipating, temperature rise is low, overload capacity is strong, low cost and other advantages
Magnetizing inrush current was very low when another outstanding advantage was Transformer Close, thereby switching overvoltage is also lower, and this is to frequency converter or extremely important with directly the link to each other safe operation of rectifier cell of transformer.
The utility model is applied to phase shifting transformer can make the converter plant floor space little, and this advantage is particularly important concerning the user, can significantly reduce user's construction investment.
