Abstract
The utility model discloses a corrugated radiator for transformer, which is applied to an electric power system. The corrugated radiator mainly comprises a corrugated pipe, oil guide pipes and an air exhaust system. The corrugated radiator is structurally characterized in that an air exhaust device and an oil guide pipeline are arranged on a radiating body by a metal corrugation radiation technology to form a sealed oil path circulating system. The corrugated radiator has the characteristics of small size, light weight, a few welding seams and large radiating area, so that a transformer is cooled efficiently and safely; and air cooler and water cooler, which are widely used at present, can be replaced. The working principle of the corrugated radiator is as follows: high-temperature insulated oil of a transformer flows into the corrugated radiating body through an upper oil guide pipe when the system operates, is radiated by two corrugated surfaces and then flows back to a transformer oil tank from a lower oil guide pipe, so that the transformer is radiated by this oil path circulation.
Description
Technical field:
The utility model relates to a kind of corrugated radiator that is applied in the electric power system, exactly is a kind of cooling and heat abstractor that is used for oil-immersed power transformer, the temperature rise of control transformer oil, the safe and reliable operation of guarantee transformer.
Background technology:
According to the needs of power industry, power equipment will be gradually to the trend development of superhigh pressure grade, and this just has higher requirement to supporting assembly.Radiator is the significant components of transformer, and the safe operation of transformer is played an important role.
Operating oil-immersed power transformer produces higher heat at positions such as winding, iron cores, thereby the temperature of transformer insulation oil is raise.For guaranteeing the normal operation of transformer, need to adopt cooler or heat sink arrangement to reduce the temperature rise of transformer.At present, domestic oil-immersed power transformer adopts but but device of device and strong oil circulation water-cooling of gilled radiator, forced oil-circulated air-cooled mostly, and the subject matter that exists in the use has:
1, gilled radiator; Adopt two versions of sewing up filled with oil, weld seam is many, and the hidden danger that is prone to the generation seepage is big; And materials are more; Volume is bigger, makes troubles for installing, transporting; Floor space is big.
2, strong oil wind cooling device, water cooler are more traditional old-fashioned cooler, only use in hydroelectric station and transformer station mostly.Though cost is lower, maintenance capacity is bigger.Exist the environmental noise height; Water resources problem be difficult for to solve, and WATER AS FLOW MEDIUM influences the insulation property of transformer oil when system's seepage, and the operation of transformer is existed potential threat.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, it is little that the purpose of the utility model provides a kind of volume, in light weight; Weld seam is few; Area of dissipation is big, and can not pollute transformer oil, satisfies the corrugated radiator of the power equipment configuration use of each electric pressure and different capabilities.
The purpose of the utility model is achieved in that the utility model mainly comprises by inside and outside two bellowss, goes up the corrugated radiator that oil guide pipe, following oil guide pipe and gas extraction system constitute.It is characterized in that: adopting forward and backward sealing plate is annular corrugated radiator with two sylphon seals; Be full of transformer oil between two bellowss; Through upper and lower Oil Guide pipeline and oil tank of transformer UNICOM, form a hermetic oil piping system, this radiator is provided with gas extraction system.Different according to the capacity of transformer and area of dissipation, the annular corrugated radiator of said structure also can be two or more.In system when operation,, drain tap is closed, and the high-temperature insulation oil of transformer is flowed through through last oil guide pipe in the ripple radiator of sealing, after the heat radiation of radiator two corrugated surfaces, flows back to the oil tank of transformer from oil guide pipe down.Make the oily temperature drop of transformer low with this oil circulation, reach the purpose of heat radiation.
Adopt the ripple heat dissipation technology, utilize bigger corrugated surface heat radiation; Reduce the temperature of transformer insulation oil through continuous oil circulation, improve radiating efficiency; Transformer oil is not contaminated; Ripple radiator weld seam is few simultaneously, reduces the hidden danger of seepage oil, reduces operation expense; Have in light weight; Characteristics easy for installation.Can realize efficient, the cooling reliably of transformer, guarantee the safe operation of system.
Below in conjunction with accompanying drawing the utility model is done with explanation
Description of drawings:
Fig. 1 is the main TV structure sketch map of the utility model;
Fig. 2 is the plan structure sketch map of the utility model:
Wherein: 1, gas exhaust piping; 2, drain tap; 3, go up oil guide pipe; 4, inner corrugated pipe; 5, outward corrugated tube; 6, following oil guide pipe; 7, preceding sealing plate; 8, back sealing plate;
Embodiment:
Can know by accompanying drawing, sealing plate 7 before the utility model adopts, back sealing plate 8, with inner corrugated pipe 4 and outward corrugated tube 5, be sealed into annular corrugated radiator.The inner charge of oil of ripple radiator, outside two corrugated surfaces heat radiation.Gas exhaust piping 1 places radiator oil-in one end with drain tap 2, through joint and atmosphere, discharges radiator ripple gas inside.Last oil guide pipe 3 places in the radiator respectively with following oil guide pipe 6, and is provided with oil guiding hole, is used for the inflow and the output of transformer insulation oil.Last oil guide pipe 3 is through flange and transformer oil upper box part UNICOM, and following oil guide pipe 6 passes through flange and transformer oil lower box part UNICOM, forms a hermetic oil circulation system.
System is when operation, and drain tap is closed.The high-temperature insulation oil nature of transformer oil upper box part flow in the ripple radiator of sealing through last Oil Guide pipeline, after the heat radiation of outside two corrugated surfaces of radiator, flow back into the oil tank of transformer from following oil guide pipe.With this continuous cycle heat radiation, make the oily temperature drop of transformer low, be reached for the purpose of transformer heat radiation.
Corrugated radiator is to place the outer independent structures of oil tank of transformer.When transformer oil weighed constantly increase, corrugated radiator also can adopt a plurality of combinations to satisfy the needs of transformer, or adopts any type of blower fan and oil pump to come enhance heat, to improve the cooling effect of transformer.
