The wind energy converter cabinet that is incorporated into the power networks
Technical field
The utility model belongs to energy technology field, relates to a kind of protective device that is incorporated into the power networks of wind power generation, relates in particular to a kind of wind energy converter cabinet that is incorporated into the power networks.
Background technology
At present, under the severe situation of energy scarcity, ecological deterioration, each country payes attention to developing green energy resource and clean energy resource more, and wherein wind power generation has obtained the development of advancing by leaps and bounds in recent years.Wind electric converter is as the important component part of wind power generation, and its performance is directly determining the development and the popularization of wind power technology.Existing wind electric converter is made up of promptly be incorporated into the power networks cabinet, control cubicle and power cabinet of three cupboards usually, and the cabinet that wherein is incorporated into the power networks is used for connecting generator system and network system, and the cabinet that is incorporated into the power networks is equipped with complete being incorporated into the power networks and protective device, plays the effect of generator connecting in parallel with system generating.
The protection device layout that is incorporated into the power networks in the cabinet of being incorporated into the power networks at present mainly is: the upper left side in rack is idle; its below arrange successively main switch, main contactor, terminal block assembly; the upper right side switch that is incorporated into the power networks of arranging in the rack; be incorporated into the power networks and be placed with switch module, lightning protection component successively under the switch; and after be incorporated into the power networks contactor and transformer be arranged on the switch fixed head, there was following shortcoming in the above-mentioned cabinet layout that is incorporated into the power networks:
1, each device placement order is unreasonable, does not come mask placement device according to the cabling flow process, causes distance between part of devices like this, needs to adopt power cable to connect, and wiring is long, wiring is more random, and the electromagnetic interference that power cable produces is bigger.2, the transformer and the contactor that is incorporated into the power networks are placed in switch fixed head back fully, cause transformer like this and the detectability of the contactor that is incorporated into the power networks and maintainable very poor.Though 3, upper left confluence copper bar the place ahead use protection network protection is because confluence copper bar still exists small objects to touch the security risk of confluence copper bar directly facing to protection network.4, since in the rack upper left very large space idle, and other place of rack more device of need arranging causes rack integral layout unshapeliness, it is comparatively crowded that some areas device is arranged, segment space but utilizes well in addition.5, power circuit have some setbacks and the path longer.
Summary of the invention
The technical problems to be solved in the utility model is at the defective that exists in the prior art, provide a kind of layout Total tune, space utilization reasonable, attractive in appearance, eliminate the wind energy converter in disorder and electromagnetic interference that produces when power cable the connects cabinet that is incorporated into the power networks.
