Problems solved by technology

[0005] The disadvantage of this balance container is that the gas tends to gradually leak from the bladder
But here, the result is that the gas volume of the bladder is gradually replaced by cooling fluid until the bladder no longer has its function and is no longer capable of pressure equalization
[0006] It is particularly problematic here that such cooling circuits are usually installed in the nacelles of wind energy installations and are thus very expensive to maintain
Refilling of the coolant can also be extremely costly
[0007] So far, no airbag or suitable gas has been found that avoids the above-mentioned problems, so that improving airbags has so far been difficult

Embodiment Construction

[0031] figure 1 A wind energy installation 100 is shown with a tower 102 and a nacelle 104 . A rotor 106 with three rotor blades 108 and a spinner 110 is arranged on the pod 104 . In operation, the rotor 106 is set in rotational motion by the wind to drive a generator in the nacelle 104 .

[0032] figure 2 A part of a liquid circuit 1 of a wind energy installation is shown schematically. The liquid circuit 1 shows a line system 2 and a subcooler 4 as well as a connection point 6 for connecting a cooling section of a component of a wind turbine, ie, for example a generator, a converter or a rectifier. here, in figure 2 These components are not shown for simplicity.

[0033]To maintain the pressure in the liquid circuit 1 , a compensating vessel 8 is provided, which is arranged here on or above the subcooler 4 . In this case, the compensating container 8 is connected to the liquid circuit 1 via a connecting line 10 which is only schematically shown here. This can be con...

Abstract

The invention relates to a wind turbine, which has a nacelle, having at least one liquid circuit (1). The liquid circuit has a cooling liquid, a cooling segment for cooling a component of the wind turbine by means of the cooling liquid, a recirculation cooler (4) for cooling the cooling liquid, a line system (2) for conducting the cooling liquid, and an equalization tank (8) for maintaining an operating pressure of the liquid circuit (1). The equalization tank (8) effects a pressure in the liquid circuit (1) by means of a static pressure of a liquid column.

Description

technical field [0001] The invention relates to a wind energy installation having at least one liquid circuit and a balancing container and to such a liquid circuit. Furthermore, the invention relates to a method for operating a wind energy installation and for operating a liquid circuit of a wind energy installation. Background technique [0002] In particular for cooling purposes, in wind turbines it is possible to use liquid circuits which conduct cooling liquid, in particular water with additives, through the respective components to be cooled. In this case, the configuration is generally such that in the liquid circuit the cooling medium is guided, in particular conveyed, to at least one component to be cooled and absorbs heat from said component there. Such a component can be, for example, a generator or a converter. The liquid thus heated is then passed on to a subcooler where it releases the stored heat again. The thus recooled liquid can then be redirected to the...
