Description
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.

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.
