Abstract
The invention discloses an oil-immersed hollow earthing reactor which comprises an oil tank, a tap switch, a coil, an N end sleeve, an X end sleeve, a lead, a clamp and a wire clamp; the coil is provided with a plurality of taps, each tap is respectively connected with the corresponding joints of the tap switch, and a public joint of the tap switch is connected with the X end sleeve by the lead; and the tap switch is fixed on a bracket nearby an outlet head of the coil by the wire clamp which is a X-type clamp. The invention regulates the number of the turns of the coil of the reactor by the tap switch so as to obtain different reactance values, only needs one sleeve or only needs one sleeve and one set of CT and can achieve the aim of outputting a plurality of different reactance values. The invention has simple structure, convenient operation and strong feasibility. The invention is more suitable for a reactor with a plurality of taps and a CT required to be installed at the end. The invention has easy arrangement of the lead, attractive appearance and low cost.
Description
One, technical field
The present invention relates to a kind of oil-immersed hollow earthing reactor.
Two, background technology
For the 500kV shunt reactor, generally all adopt and come ground connection through neutral grounding reactor.And neutral grounding reactor that is to say and need draw a plurality of taps according to a plurality of different reactance values of the general need of actual conditions of circuit.Each reactor manufacturer is for the general mode that has several taps just to draw with several sleeve pipes that adopts of this kind situation at present.But when number of taps is many, or terminal require to install current transformer, when being called for short CT, adopt when the scheme that several taps draw with several sleeve pipes is arranged, not only increased cost but also influenced attractive in appearancely, also be prone to cause the user to operate the inconvenience with wiring.
Three, summary of the invention
The present invention solves the problems referred to above that exist in the prior art, provides a kind of needs 1 branch casing, perhaps only needs 1 branch casing and 1 cover CT just can reach the oil-immersed hollow earthing reactor of a plurality of different reactance value outputs.
For addressing the above problem, technical solution of the present invention is: a kind of oil-immersed hollow earthing reactor, and it comprises fuel tank, shunting switch, coil, N end sleeve pipe, X end sleeve pipe, lead-in wire, folder and wire clamp; Coil has a plurality of taps, and each tap is linked to each other with the corresponding joints of shunting switch respectively, and the public connectors of shunting switch connects X end sleeve pipe through lead-in wire; Shunting switch is fixed near the support the coil tap by wire clamp, and said folder is the X-shape folder.Thereby make coil produce the different numbers of turn through the adjusting shunting switch and obtain different reactance values.
Above-mentioned said the present invention also comprises current transformer CT, and it is installed in the rising seat of X end sleeve pipe.
The present invention links to each other the tap of the different numbers of turn of coil with shunting switch; Thereby the number of turn of regulating reactor winding through shunting switch obtains different reactance values; Its needs 1 branch casing perhaps only needs 1 branch casing and 1 cover CT just can reach the purpose of a plurality of different reactance value outputs.The present invention is simple in structure, and is easy to operate, and feasibility is strong.More be applicable to a plurality of taps, the terminal reactor that requires to install CT.Its easy arrangement that goes between, good looking appearance, cost is low.
Four, description of drawings
Below in conjunction with accompanying drawing the present invention is done and to further describe:
Fig. 1 looks cut-away view for the master of first kind of embodiment of the present invention;
Fig. 2 looks cut-away view for the left side of first kind of embodiment of the present invention;
Fig. 3 is the cut-away view of overlooking of first kind of embodiment of the present invention;
Fig. 4 is the cut-away view of overlooking of second kind of embodiment of the present invention.
Five, embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, present embodiment comprises the interior current transformer CT and the wire clamp 8 of rising seat of fuel tank 11, shunting switch 12, coil 10, N end sleeve pipe 4, X end sleeve pipe 5, lead-in wire 6, X-shape folder 7, X end sleeve pipe.As required coil 10 is extracted out three tap X1, X2 and X3 of the different numbers of turn, tap X1, X2 and X3 are linked to each other with 3 with the corresponding joints of shunting switch 12 1,2 respectively, the public connectors X of shunting switch 12 connects X through lead-in wire 6 and holds sleeve pipes.Shunting switch 12 is fixed near the support 9 coil 10 taps by wire clamp 8.Thereby make the different numbers of turn of coil 10 generations obtain different reactance values through regulating shunting switch 12.
As shown in Figure 4; Other structure of present embodiment is together like Fig. 1, Fig. 2 and embodiment shown in Figure 3; Just extract coil 10 five tap X1, X2, X3, X4 and X5 of the different numbers of turn out, tap X1, X2, X3, X4 and X5 are linked to each other with 5 with the corresponding joints of shunting switch 1,2,3,4 respectively according to technical protocol.11 is fuel tank, and 10 is coil, and 7 is the X-shape folder, and 6 are lead-in wire, and 8 is wire clamp, and 12 is shunting switch.
