Plate radiator is used in large and super large power transformer and reactor power equipment of cooling device.Our company produces the plate radiator is adopting international advanced roll forming production line, CNC numerical control type radiator header pipe punching equipment, advanced low carbon, environmental protection surface pre-treatment production line and coating production line and the unique inner cavity processing equipment production, the MAG/MIG welding equipment, welding quality is stable and reliable, high dimensional accuracy, smooth and beautiful appearance.Because the piece type design adopted international popular advanced type, compared with the same specifications of the plate radiator with the cooling area is large, the intensity is high, no oil flow blind Angle, etc.Products of various technical indicators meet the plate radiator industry standard "JB/T5347-2013" regulation requirements.

1.Model description:

Example 1: PC3200-30/520 TH
Detachable plate radiator;Center distance - 3200, the number 30 pieces, its width 520, TH said used in humid areas.

Example 2: PCJ2600 -33(2)/(2200) -520
Gooseneck plate radiator;Long piece of center distance - 2600, the long piece number 33 piece;Short center distance of 2200, the number 2 pills;520.

Special code: use environment humid environment with "TH", tropical environment with "TA", said general environment.

2.The plate radiator specifications and technical Parameters:

Two flange plate radiator center distance is 1000 ~ 4000 mm, width is 520 mm, 480 mm, the spacing of 45 mm, number of 8 ~ 40 pills see the "plate radiator technology parameter table":

The radiator structure forms:
(1)The radiator according to the installation divided into:PG stationary and PC detachable.
PG type:stationary,don’t use the flange,direct welding on transformer tank.
PC type:detachable,through the flange fixed to the transformer tank.
(2)The radiator according to the structure can be divided into:
Conventional type:the center is the same,for example PC3200-30/520
Gooseneck type:for example PC2600(2200)-33(2)/520 the center of the film is different,the film is divided into long films and shor films,and the short film are more than two pieces.

3.Plate radiator technology parameter table

4.The plate radiator selects principle:
1, The experience method: plate radiator is chosen, the current is mainly according to the professional production companies to provide "plate radiator technology parameter table".
For reference, combining with practical work experience to choose.
2,Calculation method:according to the transformer oil tank data for calculating the effective heat dissipation area S selection;S = 0.75 S1 + K4S2 + nSz (Sf)
Among them: S1 - -- -- -- -- -- - transformer oil ㎡ area,S2 - -- -- -- -- -- - transformer tank wall ㎡ area,Sz -- -- -- -- -- -- -- each group of natural cooling effective heat dissipation of radiator ㎡ area, the technology parameters selection in the table.
Sf, -- -- -- -- -- -- -- each set of air cooling effective heat dissipation of radiator ㎡ area, the technology parameters selection in the table.N -- -- -- -- -- -- -- -- the radiator group number
K4 -- -- -- -- -- -- -- the radiator arrangement coefficient of note: 
1 / when decorate, radiators in transformer side K4 = 0.90
2 / decorate, radiators in transformer sides when K4 = 0.85
3 /, radiators K4 = 0.80 when decorate in the transformer on three sides

5.The plate radiator with the condition of air cooling device:
1, The radiator using the cold, do not need to be equipped with air cooling device.
2, P 10000 kva transformer capacity, equipped with air cooling device.
3, Other conditions of the transformer needs, equipped with 

6.Air cooling device.Six, install and use notice:
1, The radiator factory conform to JB/T5347-2013 standard for transformer with plate radiator technology requirements,
2, Radiator lumen cleanliness inspection;With pressure value is not less than 35 kv transformer oil flushing of the inspection,
3, When the radiator air tightness test;Barometric pressure is less than 0.20 MPa, the holding 20 minutes, without leakage and permanent deformation.
4, Thermal vacuum test;The vacuum degree should not be greater than 13 Pa, duration of 48 hours, without permanent deformation.
5, Transformer oil;Open the radiator air plug above, when the transformer oil spill, tighten vent plug, wiping oil spills.
6, Radiator on-site installation;The radiator on the flange cover, install docking in time, flange exposure time is less than 1 hour.
7, Radiator use environment;With matching transformer host USES environmental conditions.Storage and transportation 

7.Guidelines:
1, In order to ensure the normal use of transformer accessories and safe operation of transformer with plate radiator reference in the process of storage and transportation is carried out GB1094.1-2013, the first part of the power transformer - general rules ", JB/T5347-2013 transformer with plate radiator, GB/J148“The power transformer transport specification”.
2, The light of the specific characteristics of structure of transformer with plate radiator, radiator four groups a bracket to fission with transformer the packing and shipping.
3, The radiator in outdoor storage, they don't use waterproof material, prevent heat moisture cause the erosion effect use effect.
