Description

A kind of wall-penetrating type wind trunk heat abstractor for underground power station dish cabinet
Technical field
This utility model relates to a kind of wall-penetrating type wind trunk heat abstractor for underground power station dish cabinet, belongs to heat abstractor Field.
Background technology
Underground power station G-T protective dish cabinet, 500KV GIS protection dish cabinet and now intelligent cabinet, main transformer cooler switch board Having two ways Deng heat radiation: one is that 4 small fan heat radiations are uniformly installed at dish cabinet top, two is that a small fan is installed in dish cabinet side Heat radiation, side are installed into air port, and its principle is by arranging setting control fan start and stop by the temperature and humidity controller in dish cabinet, as Right bank main transformer cooler switch board is crossed when temperature in small stream Lip river > 30 DEG C time start exhaust fan, the temperature of components and parts in reducing dish cabinet.
Small stream Lip river is crossed right bank main transformer cooler switch board and is arranged in main transformer hole, has the 550KV main transformer pressure taking to run before cabinet Device, against wall after cabinet, side is to enter door, is main transformer transport passage for transporting outdoors, and this door is arranged on isolation main transformer and transport passage for transporting Closing wall on, this door is chronically at closed mode.Main transformer cooler switch board is the most inaccessible, and circulation is not good enough, causes In-cabinet temperature is higher, and components and parts such as oil pump electrical source of power sky leaves terminal stud and burns black, PLC control module temperature drift etc., seriously Threat equipment is properly functioning.
Right bank every 550KV main transformer configuration a set of forced oil circulation water-cooling but device is crossed in small stream Lip river, including 6 water valves and 6 oil Pump and PLC PLC technology unit thereof.This cabinet collection AC three-phase 220V forceful electric power loop, direct current 220V electric power loop, 24V PLC control Loop processed is in one, and during operation, a components and parts heating is serious.Such as ambient temperature (cabinet inner wall temperature) in certain main transformer cooler cabinet 46 DEG C, 6 oil pump skies are opened upper connecting terminal and are all 80 DEG C--and 81 DEG C.The ambient temperature of 16B is 41 DEG C--43 DEG C, and 6 oil pump skies Open upper connecting terminal and be all about 65 DEG C.
It is no exception that right bank GIS 9821 communication device is crossed in small stream Lip river, its backboard temperature be 46 DEG C (look into description, properly functioning Temperature-10 DEG C--55 DEG C), breaker operation cabinet temperature 43 DEG C (look into description, normal operating temperature-10 DEG C--40 DEG C).GIS is big Room temperature drift, the most only two exhaust outlets, cooling-down effect is poor.
The heat radiation of present stage underground power station main transformer cooler switch board has a disadvantage in that
One, fan power the least (10W), even if fan is all turned on, dish in-cabinet temperature also reduces seldom, environment temperature in cabinet Spend the most higher.
Two, air inlet is less than normal, has wiring etc. in terminal block, dish to block around air inlet, and air inlet effect is bad.
Three, air outlet is only the perforate of several small fan, and area is less than normal, and air-out volume is little, and in dish cabinet, heat can not be a large amount of Discharge, cause dish in-cabinet temperature to remain high.
Utility model content
This utility model is for the deficiency of existing heat abstractor, it is provided that a kind of wall-penetrating type strong wind for underground power station dish cabinet Road heat abstractor, this air exhausting device simple in construction, it is easily worked manufacture, can promote owing to the heat radiation of underground power station secondary dish cabinet is dropped Temperature, with ensure equipment under allowing temperature range or lower temperature properly functioning.
In order to realize above-mentioned technical characteristic, the purpose of this utility model is achieved in that a kind of for underground power station The wall-penetrating type wind trunk heat abstractor of dish cabinet, it includes wall-penetrating type air channel, and described wall-penetrating type air channel is internally installed multistorey strainer mesh, The air inlet in described wall-penetrating type air channel is connected with main transformer passage, is also equipped with high-power air draft inside described wall-penetrating type air channel Fan, after described high-power exhaust fan is arranged on filter screen, the air outlet in described wall-penetrating type air channel and the trailing flank air inlet of dish cabinet Being connected, the bottom of the front cabinet door of described dish cabinet is provided with air outlet.
Described dish cabinet is internally installed Quadratic Finite Element device, and described dish cabinet is arranged on inside the transformer chamber of underground power station.
Described dish cabinet is internally installed temperature sensor, and holding wire and high-power exhaust fan phase are passed through in described temperature sensor Even control it to open and close.
Described filter screen uses the drainage screen matched with high-power exhaust fan, respectively installs at air inlet and electric fan air intake direction One.
Described wall-penetrating type air channel uses cylindrical shape to cover aluminum zine plate.
Described air outlet uses the grid type shutter carrying filter screen.
This utility model has the advantages that:
One, big due to exhaust fan power, wind path circulation canal increases, and exhaust effect is good, and dish in-cabinet temperature reduces fast, is suitable for Property is strong.
Two, this heat abstractor is automatically controlled start and stop by temperature controller, and maintenance is little, and maintenance is convenient.
Three, this heat abstractor is arranged between wall and dish cabinet, and material hardness is high, good stability.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: dish cabinet 1, front cabinet door 2, air outlet 3, Quadratic Finite Element device 4, high-power exhaust fan 5, filter screen 6, wall-penetrating type air channel 7, main transformer enclosure wall 8, air inlet 9, main transformer passage 10, underground power station transformer chamber 11.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
As it is shown in figure 1, a kind of wall-penetrating type wind trunk heat abstractor for underground power station dish cabinet, it includes wall-penetrating type air channel 7, described wall-penetrating type air channel 7 is internally installed multistorey strainer mesh 6, and the air inlet 9 in described wall-penetrating type air channel 7 is connected with main transformer passage 10 Logical, described wall-penetrating type air channel 7 is internal is also equipped with high-power exhaust fan 5, after described high-power exhaust fan 5 is arranged on filter screen 6, The air outlet in described wall-penetrating type air channel 7 is connected with the trailing flank air inlet of dish cabinet 1, and the bottom of the front cabinet door 2 of described dish cabinet 1 sets It is equipped with air outlet 3.
