Abstract
The utility model relates to an auxiliary spraying device for an external air cooling system of a DC converter station, which comprises a water pump, wherein a water inlet of the water pump is communicated with a cooling water pipe, and a water outlet of the water pump is communicated with a spraying water pipe; the cooling water pipe is communicated with the water inlet of the water pump through a water processing filter, and the water outlet of the water pump is communicated with the spraying water pipe through a water softener; and a plurality of nozzles are arranged on the spraying water pipe, and components are sequentially connected by hoses. The auxiliary spraying device for the external air cooling system of the DC converter station makes up for the defect that the external air cooling system of the DC converter station has insufficient cooling capacity at extreme high temperature in summer, ensures the normal operation of a valve cooling system, ensuring the safety and reliability of the converter station, has convenient installation and use, and is especially suitable for the auxiliary cooling of the external air cooling system of the DC converter station in cold winter or at extreme high temperature in summer.
Description
Technical field
The utility model relates to a kind of power system components and parts cooling system, particularly a kind of outer air-cooled auxiliary spray equipment of DC converter station that is used for.
Background technology
Converter valve is the nucleus equipment of DC converter station, and valve cooling system plays crucial effects to the safe and stable operation of converter valve, cooling and outer cooling system in valve cooling system comprises.Internal cooling system is divided into water cooling, air cooling, oil cooling and but cools off with freon; Outer cooling system is divided into outer water-cooled and air-cooled outward.Valve cooling system cools off straight-flow system nucleus equipment converter valve by internal cooling system, takes away a large amount of heats that produce in the converter valve running, guarantees the reliability service of converter valve.The internal cooling system of the valve cooling system of DC converter station use at present is generally water cooling.
For the DC converter station that is installed on winter severe cold area (outside air temperature is lower than zero degree), if adopt the mode of water-cooling system in the outer water-cooling system cooling, the situation that cooling water freezes takes place easily, cause valve cooling system normally to move, cause temperature of heating elements too high, influence the operate as normal of converter valve.Therefore, for the DC converter station that is installed on the winter severe cold area, should adopt the mode of the cooling of water-cooling system in the outer air cooling system cooling.Yet, because the cooling capacity of outer air cooling system is limited, summer thermal extremes weather the situation of cooling capacity deficiency appears easily, cause valve cooling system normally to move, cause temperature of heating elements too high, influence the operate as normal of converter valve.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of air-cooled auxiliary spray equipment outside the DC converter station that is used for of reasonable in design, remedied outer air cooling system cooling capacity defect of insufficient, guarantee the normal operation of valve cooling system, guaranteed the safe and reliable of current conversion station.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of outer air-cooled auxiliary spray equipment of DC converter station that is used for, comprise water pump, and the water inlet of water pump is communicated with cooling water pipe, and the delivery port of water pump is communicated with spray header.
Cooling water pipe is communicated with the water inlet of water pump by water treatment filter.
The delivery port of water pump is communicated with spray header by water softener.
A plurality of shower nozzles are installed on the spray header.
Adopt flexible pipe to connect between each parts that is connected successively.
The utility model provides is used for the outer air-cooled auxiliary spray equipment of DC converter station, and beneficial effect is as follows:
1, because cooling water pipe is communicated with spray header by water pump, during use spray header is installed on the exogenous wind cold water pipes top of outer air cooling system, in cooling water pipe, import cooling water, cooling water sprays from spray header by after the water pump supercharging, water to drench and played the effect that cools on the exogenous wind cold water pipes, remedied outer air cooling system cooling capacity defect of insufficient, guaranteed the normal operation of valve cooling system, guaranteed the safe and reliable of current conversion station, easy to install, be particularly useful for winter severe cold, the auxiliary temperature-reducing that has the outer air cooling system of DC converter station of thermal extremes weather summer.
2, water treatment filter is the aseptic filtration device of liquid, have that volume is little, in light weight, filter area is big, the rate of filtration is fast, filtering accuracy is high, plugging rate is low, the advantage of pollution-free, acid-alkali-corrosive-resisting, can remove the impurity in the cooling water that flows into water pump effectively, avoid impurity to damage water pump, guaranteed the normal safe operation of package unit.
3, water softener has reduced original water hardness, has reached the purpose of softening of water, thereby avoids carbonate to produce scale formation in pipeline, can guarantee carrying out smoothly of package unit again when reducing investment outlay cost greatly.
4, a plurality of shower nozzles of installing on the spray header make cooling water be sprayed at equably on the exogenous wind cold water pipes, guarantee the water distribution effect, make the cooling of exogenous wind cold water pipes evenly.
5, adopting flexible pipe to connect between each parts makes each parts to remove and install easily.
Description of drawings
Below in conjunction with drawings and Examples patent is described further:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a user mode schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises water pump 3, and the water inlet of water pump 3 is communicated with cooling water pipe 1, and the delivery port of water pump 3 is communicated with spray header 5.
Cooling water pipe 1 is communicated with the water inlet of water pump 3 by water treatment filter 2.
The delivery port of water pump 3 is communicated with spray header 5 by water softener 4.
A plurality of shower nozzles are installed on the spray header 5.
Adopt flexible pipe to connect between each parts that is connected successively.
As shown in Figure 2, the course of work of the present utility model is as follows:
During use spray header 5 is installed on the top of the exogenous wind cold water pipes 6 of outer air cooling system, imports cooling water in cooling water pipe 1, cooling water sprays from the shower nozzle of spray header 5 after by water pump 3 superchargings, waters and drenches on the exogenous wind cold water pipes 6.
Cold water water pipe 1 can be communicated with the fire main pipe, fetches water from fire protection pipeline, also can be communicated with the domestic water house steward, fetches water from the domestic water pipeline.
