Description
Technical field
This utility model relates to a kind of dry excitation transformer chiller, it is adaptable to dry excitation transformer force wind
Cold.
Background technology
Exciting transformer is the visual plant in power plant, and current most of exciting transformer patterns are dry-type transformer, and
It is not provided with chiller, normal by its temperature of natural air cooled holding.For some undergroundhydropower station, due to running environment relatively
Difference, air flow property is bad, and the reason such as unit often long-time oepration at full load, and exciting transformer long-play can be led
Cause iron core and winding temperature is higher, often exceed its alarming value, have a strong impact on equipment safe and stable operation.So design one is dry
Formula exciting transformer chiller, it is possible to temperature when effectively reducing exciting transformer long-play is pacified for exciting transformer
Full stable operation is most important.
Summary of the invention
The purpose of this utility model is overcome the deficiencies in the prior art and provide a kind of dry excitation transformer cooling dress
Putting, solve the problem that built power station excitation transformer temperature is too high, the design of this device is simple, cheap, easy for installation, effect
Fruit substantially, can effectively reduce field core and winding temperature, exciting transformer safe and stable operation has been effectively ensured.
Realizing the technical scheme that this utility model purpose used is, a kind of dry excitation transformer chiller, at least
Including blower fan and blower fan fixation kit, described blower fan fixation kit is the wind that the upper cover being buckled on base by base and cover is constituted
Case, described base is the excitation-transformation variable cabinet top that web plate, base through screws and packing ring are installed on dry excitation transformer, screw
Being positioned in the mesh of base, be provided with assembling position in the middle part of base, blower fan is fixed in bellows and wind by assembling position
Upward, the lower surface of base is provided with more than 3 snubber blocks, the top board of described upper cover offers flexible in the air draft direction of machine
Hole, round tube hole is positioned at the surface of assembling position, is provided with circular grill in round tube hole, and one of them side plate of upper cover sets
There is wire bushing pipe.
Described base and upper cover are corrosion resistant plate, and base is connected by screw with upper cover.
Bellows are provided with two blower fans, two fan parallel-connections.
The side plate of described upper cover is web plate.
The outer surface of bellows is provided with strip fin.
As shown from the above technical solution, the dry excitation transformer chiller that this utility model provides, device is arranged at
The excitation-transformation variable cabinet top of dry excitation transformer, owing to exciting transformer long-play can cause iron core and winding temperature relatively
Height, the hot-air of iron core and winding adnexa focuses primarily upon excitation-transformation variable cabinet top, and the lower surface of base is provided with more than 3 and subtracts
Shake block, on the one hand snubber block reduces the vibrations produced when blower fan rotates, and on the other hand rising and flowing for hot-air provide sky
Between, during fan operation, bellows form pressure reduction with extraneous, and hot-air accelerates to rise under differential pressure action, and the base of bellows is web plate,
Hot-air is entered in bellows and by blower fan from being positioned at the round tube hole directly over assembling position extraction by the mesh of base,
Owing to excitation-transformation variable cabinet is mounted on ground, the air draft direction of blower fan is set upward, hot-air is evacuated on excitation-transformation variable cabinet
Side, it is achieved the cooling of excitation-transformation variable cabinet；The fixing of base is realized by screw and packing ring, and screw is positioned in the mesh of base, closes
Reason utilizes the mesh that base is intrinsic, because of without additionally offering screwed hole, logical when mesh diameter is more than screw head size
Cross packing ring and fix screw；Round tube hole is provided with circular grill, it is to avoid the foreign material dropped affect blower fan and rotate；The outer surface of bellows
On strip fin is set, auxiliary wind box dispels the heat.
Compared with prior art, the advantage of the dry excitation transformer chiller that this utility model provides is: 1. system
Making this device material requested is corrosion resistant plate and conventional blower, and all there is spare part in warehouse, general power station, and material is simple and easy to get, and price is low
Honest and clean；2. this device is case structure, designs simple, easy for installation；It is connected tightly with excitation-transformation variable cabinet bottom the most box chiller
Close, the air draft direction of assembling is outside, and cooling effect is obvious.
