Description
Technical field
The utility model relates to a kind of sink, particularly a kind of sink of low-voltage crossing current transformer tower cylinder.
Background technique
Low-voltage crossing is the guarantee that is applied to the grid-connected stability of power generating equipment of wind-powered electricity generation, field of solar energy, is the professional standard that national grid is executed.In the process of low-voltage crossing, grid side rectifier part need to be sent the wattless current that exceedes rated nominal current several times electrical network is supported, pusher side inverter section arrives on the energy flux path of chopper (chopper) in generator simultaneously, have huge active current and flow through inverter, consume on chopper (chopper).
In wind-powered electricity generation field, low-voltage crossing equipment is generally arranged on tower cylinder bottom, and the air-cooled double-fed wind power generator group of the 1.5MW of domestic main flow, its current transformer is also arranged on tower cylinder bottom.Because low-voltage crossing equipment is under nominal situation, provided under nominal situation the delivery of electrical energy path between generator set and electrical network by bypass thyristor.Therefore, general in wind power generating set Operation at full power, the also operating mode in Operation at full power of the bypass thyristor of low-voltage crossing equipment, now, the heat radiation of current transformer, the heat radiation of low-voltage crossing equipment, all discharge rack separately with the air-cooled situation of dispelling the heat, be discharged among the space of tower cylinder first layer.If the endurance is longer; under the higher operating mode of ambient temperature, easily produce too high ambient temperature at tower cylinder first layer, cause the electrical control cabinet report excess temperature fault such as current transformer, tower cylinder control cabinet; cause shutdown, thereby affect wind power generating set complete machine generating dutation and benefit.
Summary of the invention
Easily produce the problem of high temperature in order to solve existing low-voltage crossing equipment installation environment, the utility model provide a kind of performance of ventilating good, the low-voltage crossing current transformer tower cylinder sink of easy installation simple in structure.
The utility model solves the problems of the technologies described above adopted technological scheme:
A kind of low-voltage crossing current transformer tower cylinder sink, be arranged in tower cylinder, for the heat radiation of current transformer, low-voltage crossing equipment, it is in tower cylinder first layer that described current transformer and low-voltage crossing equipment are arranged on tower cylinder bottom, described low-voltage crossing equipment both sides are provided with front cabinet door grid and rear guiding-grid, described sink comprises vent passages, adds strong wind fan, the described strong wind fan that adds is arranged between low-voltage crossing equipment and rear guiding-grid, described vent passages is positioned at the side top of rear guiding-grid, and described vent passages enters the tower cylinder second layer through tower cylinder first layer.
Further, described in, add the strong wind fan installation that is inclined upwardly.
Further, described vent passages is provided with entrance and exit, and described entrance is just to rear guiding-grid, and described outlet is positioned at the tower cylinder second layer, and the described tower cylinder second layer is provided with exhaust outlet.
Further, described vent passages at least comprises one section of face formation wind-guiding oblique angle that is inclined upwardly.
Further, described in add strong wind fan and at least comprise a large power shaft flow fan, described large power shaft flow fan is arranged on and in assembling seat, forms blower fan module.
The utility model compared with the existing technology has the following advantages and effect: 1, between low-voltage crossing equipment and rear guiding-grid, be provided with and add strong wind fan, and add the strong wind fan installation that is inclined upwardly, make the thermal air current of low-voltage crossing equipment discharge to being inclined upwardly, be more prone to be discharged from, and after discharging, except hot air own vol expands the trend moving upward of bringing, also there is certain initial velocity component moving upward.2, between tower cylinder first layer and the tower cylinder second layer, set up special vent passages, the hot blast that low-voltage crossing equipment is discharged, lead fast the second layer space of tower cylinder, because the space of the tower cylinder second layer is huge, tower barrel and air surface of contact are large, the normal temperature air bulky of the tower cylinder second layer, therefore, after hot air is discharged to the tower cylinder second layer, because mix with original cool air, temperature is reduced to normal temperature gradually, can not impact the ambient temperature of tower cylinder first layer.3, because the exhaust air rate of low-voltage crossing equipment increases, the air output of tower cylinder first layer is increased, indirectly reduce the ambient temperature of tower cylinder first layer, to being arranged on the normal operation of current transformer, low-voltage crossing equipment, tower cylinder control cabinet of tower cylinder first layer etc., brought positive guarantee.4, vent passages is low-voltage crossing equipment cooling air draft specialized designs, comprises one section of face that is inclined upwardly and form wind-guiding oblique angle in vent passages, is more conducive to the discharge of hot gas.5, vent passages and the installation that adds strong wind fan do not affect each equipment of original interior tower cylinder, convenient installation.6, simple in structure, saving cost.
