Abstract
The utility model discloses a functional type wind power combined box substation structured like a Chinese character 'pin', which adopts the following structure: a transformer oil tank and a high-voltage box body and a low-voltage box body which are respectively positioned on two sides thereof are shaped like a Chinese character 'pin'; the height of the high-voltage box body is larger than the height of the low-voltage box body; an isolation knife on a composite apparatus of a fuse and a load switch is arranged inside a cable chamber; an arc chute and the fuse are arranged inside a load switch chamber; and a radiating plate communicated with the transformer oil tank is arranged on one side thereof. The substation has the advantages of reasonable and compact structure, low manufacturing cost, safe and reliable performance, aesthetic appearance, and all-directional protection.
Description
Technical field
The utility model relates to a kind of used for wind power generation box-type substation.
Background technology
The used for wind power generation box-type substation is to be used in the wind-driven generator outlet, and voltage is boosted to the electric equipment that is connected to the grid behind the 35Kv (10kV) by 0.69kV.Existing box-type substation ubiquity production cost is higher, structural design is unreasonable, and profile is not attractive in appearance, radiating effect is bad, the shortcoming that security performance is relatively poor.
Summary of the invention
For solving the problems referred to above that existing preassembled transformer station exists, the utility model provides a kind of delta structure used for wind power generation box-type substation, and its technical scheme of taking is:
This transformer station comprises the high pressure casing, oil tank of transformer, with the low pressure casing, the front of high pressure casing one side is the low pressure casing, the back is an oil tank of transformer, they are delta structure, the high-voltaghe compartment height is in the low pressure casing, the high pressure casing is divided into cable vault and on-load switch chamber, be provided with switch-fuse combination in the high pressure casing, wherein the isolation knife on the switch-fuse combination is located in the cable vault, and that on-load switch and circuit breaker are located at on-load switch is indoor, be provided with low-tension switch cabinet in the low pressure casing, the rear side of oil tank of transformer is provided with the fin that is communicated with it, the top of oil tank of transformer is provided with transformer oil level meter, Buchholz relay and pressure relief valve, fin, oil level indicator, the equal open type of Buchholz relay and pressure relief valve is installed, be provided with U.S. variant transformer body in the oil tank of transformer, the front side of oil tank of transformer is provided with low-tension bushing, its left side is provided with bushing, the transformer body connects low-tension switch cabinet respectively by bushing connected load switch-fuse combined electric apparatus by low-tension bushing.The arrangement of oil tank of transformer, high pressure casing and low pressure casing makes complete machine form delta structure, compactness reasonable in design; Radiating mode has used for reference U.S. change transformer body and fin is exposed to outdoor mode, makes radiating effect more obvious, and equipment such as transformer oil level meter, Buchholz relay and pressure relief valve are all isolated convenient the tour and maintenance fully with charged position; Isolate with switch in different intervals, when opening isolation, can guarantee the safe maintenance of carrying out switch; The switch that the high-pressure side adopts Europe to become has solved U.S. change and has protected incomplete shortcoming; There is tangible cut-off point the high-pressure side, can guarantee the fail safe of separate unit interruption maintenance; The high-low pressure housing height basis height of equipment is separately made the different casing of height, makes more compact structure, effectively reduces cost.
Therefore the utlity model has compactness rational in infrastructure, production cost is low, and performance is safe and reliable, the characteristics of good looking appearance.
