Description
Technical field
The utility model belongs to distribution transformer corollary apparatus technical field, especially relates to a kind of distribution transformer heat sink.
Background technology
Distribution transformer is the visual plant in transformer station's power supply-distribution system, and the transformer that distribution substation is selected for use usually is an oil-filled transformer, and distribution transformer can produce great amount of heat when running; Cause the temperature of transformer to raise and frequent tripping operation; The long term high temperature operation is prone to cause insulation property to reduce, and loss increases electric power; The transformer burnout failure appears when serious, the influence power supply.
At present, fan for cooling is still adopted in the cooling of distribution transformer mostly, and radiator fan is installed in transformer cabinet bottom; Through the heat radiation window heat radiation of bottom, the hot-air density that produces during owing to operation is little, and hot-air accumulates in transformer cabinet top in a large number and can't discharge; Radiating effect is not obvious; And this radiating mode accumulates a large amount of dust etc. in the long-time running process because in the equipment, is prone to cause stopping up fan, directly causes heat abstractor to move.
Summary of the invention
For addressing the above problem, the purpose of the utility model provides a kind of distribution transformer heat sink of safe and reliable, good cooling effect.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of distribution transformer heat sink; It is connected to form by aqua storage tank, circulating water pump, drainage pipe and sparge pipe successively, and the control gate valve is installed between drainage pipe and the circulating water pump, and the drainage pipe outer cover is provided with an outer tube; Be equipped with coolant in the cavity between outer tube and the drainage pipe; Between drainage pipe and the sparge pipe flow control valve is installed, is evenly distributed with several hole for water sprayings on the sparge pipe, the hole for water spraying place is equipped with nozzle.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This distribution transformer heat sink, it is simple in structure, and is reasonable in design, easy to operate, safe and reliable, can guarantee the temperature of the normal operation of transformer, good cooling effect effectively to the transformer cooling.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: the 1-sparge pipe; The 2-nozzle; The 3-flow control valve; The 4-drainage pipe; The 5-outer tube; 6-controls gate valve; The 7-circulating water pump; The 8-aqua storage tank; The 9-radiating fin of transformer.
Embodiment
Below through embodiment and combine accompanying drawing that the utility model is done further explain.
As shown in Figure 1, this distribution transformer heat sink, it is connected to form by aqua storage tank 8, circulating water pump 7, drainage pipe 4 and sparge pipe 1 successively; Control gate valve 6 is installed between drainage pipe 4 and the circulating water pump 7; Drainage pipe 4 outer cover are provided with an outer tube 5, are equipped with coolant in the cavity between outer tube and the drainage pipe, between drainage pipe 4 and the sparge pipe 1 flow control valve 3 are installed; Be evenly distributed with several hole for water sprayings on the sparge pipe 1, the hole for water spraying place is equipped with nozzle 2.
During use, sparge pipe is arranged on the transformer radiator top, and the nozzle of sparge pipe bottom is towards transformer radiator; Aqua storage tank is placed on the transformer radiator below; Manually opened control gate valve, circulating water pump are extracted the water in the aqua storage tank out and are introduced in the drainage pipe, in drainage pipe after coolant is through flow control valve regulation flow; Nozzle ejection on sparge pipe is lowered the temperature to transformer radiator; The water that is absorbed with heat under spraying flows in the aqua storage tank, is extracted out by circulating water pump once more and introduces in the drainage pipe, and after the coolant cooling, the nozzle from sparge pipe sprays, and transformer radiator is lowered the temperature; Repeat said process, the temperature when the distribution transformer actuator temperature reaches normal operation, manual-lock control gate valve.
