The single group of power transformation part iron core is laminated seven grades of mitres of horizontal direction dislocation not punch structure using monolithic, constitutes iron
The upper and lower yoke monolithic of the monolithic of core point, newel monolithic, left and right five kinds of lateral column monolithic, upper and lower yoke monolithic left and right ends are inside
45° angle, middle inner side is 90 ° of angles provided with 90 ° of angles, newel monolithic upper and lower ends, and left and right lateral column monolithic upper and lower ends are inside
45° angle, with being arranged between the adjacent upper yoke monolithic 45° angle in group by horizontal direction dislocation 3mm, with upper yoke monolithic in one-level with
Yoke monolithic is arranged on the contrary, left side post monolithic misplaces with the arrangement of right side post monolithic on the contrary, being laminated horizontal direction to monolithic by that analogy
Seven grades of mitres not punch structure single group, then combined by single group and to form multigroup monolithic stacking horizontal direction and misplace seven grades of mitres not
Punch structure.
Oil circuit and oil channel structures are redesigned in order to reduce temperature rise in the present embodiment, are mainly reflected in：In stream
In oily area, laterally, to oil duct, highly control is not more than 6 mm to fir, and the longitudinal oil duct width in exterior loop outside controls to be not more than
12mm, interior loop oil duct width is within the scope of 18-22mm.
The oil stream Distribution of temperature rise that this new design can obviously improve in oil stream and Distribution of temperature rise in Liu You areas, Liu You areas is equal
Even, oil duct declines without stagnant thermal phenomenon, oil stream speedup temperature rise, and few with oil.
Because such as oil duct height is bigger, velocity flow profile is more uneven between horizontal oil duct in oily area, and unfavorable shadow is produced to temperature rise
Ring.
And if inner-outer coil longitudinal direction oil duct width is identical, then longitudinal oil duct section of exterior loop is much larger than interior loop, make
Interior loop is much smaller than into outside line astragal cake area internal resistance so that most of oil pours off from exterior loop, and interior lines coil temperature rise is higher.
In above-mentioned horizontal integration pole type transformer platform matches somebody with somebody power transmission system, carry out becoming the process with power transmission using the system
For：1st, the high-tension electricity in power network high-voltage line is introduced by the transformer ripple tank wall that oil becomes part by bushing；2nd, by oil
High-tension electricity change is pressed into low tension by the transformer for becoming part by electromagnetic conversion；3rd, again by the external power transmission of comprehensive distribution box, simultaneously
Comprehensive distribution box has the functions such as reactive-load compensation, earth leakage protective, low pressure reclosing, low-temperature measurement synthesis.
Using comprehensive distribution box and transformer body lateral arrangement, corrugated tank wall is arranged in three sides of fuel tank, and small volume is held
Measure big temperature rise low, low-tension bushing is inserted directly into power transformation fuel tank by comprehensive distribution box rear portion and is allowed to the decline of distribution fault rate, and reduction stops
The electric time, and directly save (300) 15 meters of low-voltage cable ZC-YJV-0.6/1kV-1 × 150 and the loss of reduction distribute-electricity transformer district.
Lateral arrangement, meets distribution assembling " complete set, integration, intellectuality " development trend, improves distribution network engineering quality, lifting work
Make benefit.To reach " compact conformation, simple installation, O＆M are convenient, sturdy and durable, energy-conserving and environment-protective ".It is adapted in city rural power grids 10kV
" the integrated pole type transformer platform widely applied in the construction of pole distribution transformer platform area and transformation（Laterally）”.To solve city
Distribution transformer platform area " dirty, unrest, difference " phenomenon on rural power grids 10kV posts.
