Abstract
The utility model relates to a shunt capacitor apparatus for a power system. The apparatus comprises a plurality of capacitor element groups, intergroup insulating components, an encapsulation component, outgoing lines, an outgoing line connector, an outgoing sleeve and a housing; each of the intergroup insulating components is arranged between each two adjacent capacitor element groups; the plurality of capacitor element groups are respectively connected with the outgoing line connector by the respective outgoing lines; the outgoing line connector is connected with the outgoing sleeve; the plurality of capacitor element groups, the intergroup insulating components and the outgoing lines are arranged inside the encapsulation component; and the housing is sleeved on the encapsulation component. Compared with the prior art, the technology employed in the utility model enables the provided apparatus to have advantages of low cost, high security, and good reliability and the like.
Description
Technical field
The utility model relates to a kind of correlation technique of electric power system, especially relates to a kind of shunt capacitance device that is used for electric power system.
Background technology
Traditional high-voltage capacitor is oil immersion aluminium foil electrode product.Because there is seepage inevitably in the existence of impregnation oils, even the danger of burning; Add and adopt hermetically sealed shell, possibly explode sometimes.Therefore, cause very burden for installation and use, especially be not suitable for the higher occasion of security requirement.In order to address the above problem, a kind of dry self-healing high-voltage power capacitor has appearred in recent years, and it is potting resin in the enclosure; The metal slide block is housed on contact conductor; The gas that when component wear, produces makes shell deformation, and the pulling slide block makes capacitor break away from operation.The problem of its existence is: 1, when integral body is used resin-encapsulated, even adopt vacuum encapsulation process, because the complicated emptying bubble fully of interior shape causes partial discharge bigger.2, whole with after the resin-encapsulated, if from slide block at a distance during component wear, energy is lower, causes slide block to be failure to actuate, and makes the protective device can not action message.
The utility model content
The purpose of the utility model is exactly to provide in order to overcome the defective that above-mentioned prior art exists that a kind of cost is low, safe, the shunt capacitance device that is used for electric power system of good reliability.
The purpose of the utility model can realize through following technical scheme:
A kind of shunt capacitance device that is used for electric power system; It is characterized in that; Comprise insulating part, encapsulation piece, lead-out wire between a plurality of capacitor element groups, group, go out wiring connector, outlet sleeve pipe and shell; Insulating part is located between the neighboring capacitors element group between described group, described a plurality of capacitor element groups respectively the lead-out wire through separately with go out wiring connector and be connected, describedly go out wiring connector and be connected with the outlet sleeve pipe; Insulating part, lead-out wire are located in the encapsulation piece between described a plurality of capacitor element group, group, and described shell is enclosed within on the encapsulation piece.
Described capacitor element group is provided with 2～6.
Each capacitor element group comprises a plurality of capacitor elements and brace, connects through brace between described a plurality of capacitor elements, and described brace is connected with lead-out wire.
Described capacitor element is provided with 2～6.
Compared with prior art, the utlity model has that cost is low, safe, good reliability, can be used for high-tension electric power system.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1; A kind of shunt capacitance device that is used for electric power system; Comprise insulating part 2, encapsulation piece 3, lead-out wire 6 between three capacitor element groups 1, group, go out wiring connector 7, outlet sleeve pipe 8 and shell 4; Insulating part 2 is located between the neighboring capacitors element group 1 between described group, described three capacitor element groups 1 respectively the lead-out wire 6 through separately with go out wiring connector 7 and be connected, describedly go out wiring connector 7 and be connected with outlet sleeve pipe 8; Insulating part 2, lead-out wire 6 are located in the encapsulation piece 3 between described three capacitor element groups 1, group, and described shell 4 is enclosed within on the encapsulation piece 3.
Each capacitor element group comprises three capacitor elements and brace 5, connects through brace 5 between described three capacitor elements, and described brace 5 is connected with lead-out wire 6.
The shell 4 usefulness sheet metals sealing welding of this shunt capacitance device is processed, and capacitor element adopts and reveals paper tinsel formula structure, is formed through coiling by aluminium foil therebetween film paper complex media or full film medium as pole plate.Capacitor element connects by parallel way, to satisfy the requirement of different voltages and capacity.Each capacitor element has all been gone here and there a fuse, and when certain component breakdown, the intact element parallelly connected with it promptly to its discharge, makes fuse quick-break in the time of Millisecond, with the fault element excision, thereby makes capacitor can continue to move.
