In addition, inside and outside pair of conductive spring structure can effectually reduce conducting rod length, and the reasonable conducting rod internal and external surface that utilizes realizes that the electric current is at conducting rod internal and external surface than evenly distributed.
Description
Technical field
The utility model relates to 10000A big current energized structural, is applied to 1100kV breaker in extra high voltage and combined electrical apparatus.
Background technology
Along with the constantly progress of China's power system technology, Ge great High-Voltage Electrical Appliances manufacturing company research and development strength constantly strengthens, high-voltage switch gear structure is more reasonable, performance is more reliable, and China has had enough strength to carry out research and development and the production of superhigh pressure and ultra high voltage High-Voltage Electrical Appliances; Further, along with national economic strength strengthens, the continuous enforcement of great national construction project and development of the West Regions, also day by day increase the demand of high voltage switchgear, electric pressure is progressively gone forward one by one to 800kV by 330kV, 550kV.Current, country also been proposed the scheme of development extra-high voltage grid, and the electric pressure of High-Voltage Electrical Appliances rises to 1100kV, and China has become first country 1100kV electrical network being carried out to commercial applications in the world.
The transmission voltage of power transmission and transforming equipment is more high more economical, but in order to transmit more electric power, only raising transmission voltage grade DeGrain, still needing and increase the electric current of transmission, effectively could increase transmission capacity like this.At present, in the High-Voltage Electrical Appliances of 126kV and 252kV, rated current mostly is 2000A to 4000A, and after boosted voltage grade, the ability of conveying electric current also needs to increase, and by the through-flow 6300A of initial line design, rapid increase-volume to 8000A, then arrives 10000A.
When electric current is less, the Mume flower contact structure of a power spring or 32 easily can realize the design of through-current capability, but after electric current increases, and being not simply increases power spring number and Mume flower contact sheet number just can realize.Economically, adopt power spring more more economical than Mume flower contact, cost performance is higher.Therefore, in through-flow design, many employing power spring structures.After increasing electric current, first expect the power spring that use 2 is parallel, but the through-current capability of two parallel power springs can not become 2 times of a power spring through-current capability effectively, due to the impact of the approach effect of electric current in conducting process.Especially, when designing the through-current capability of 10000A, common calculating needs at least 4 power springs, but how power spring is arranged, the physical dimension of conductive trough becomes crucial.
Summary of the invention
The purpose of this utility model is for the electrical equipment in ultra high voltage field provides 10000A big current energized structural, and needs long-term reliably through-flow, processing and assembling simple and reliable process, be convenient to realize, guarantee High-Voltage Electrical Appliances long-term stability run.
The utility model is achieved by the following technical solution:
10000A big current energized structural, comprises conducting rod, interior contact base, fairlead, inner ring power spring, outer ring power spring, outer contact base, radome, internal fixation screw, outer set screw, radome hold-down screw and pedestal.Interior contact base designs power spring mounting groove and fairlead mounting groove simultaneously, after power spring and fairlead are installed, is conducive to the even contact ensureing conducting rod and power spring; In addition, ensured the axiality of outer contact base and interior contact base by design, be also conducive to ensureing the power spring of outer contact base and the axiality of conducting rod; Inside and outside contact base is installed the structure of power spring simultaneously, is conducive to realizing uniform current and flows through power spring, reduce the kelvin effect of conductive surface, be more conducive to the realization that big current is through-flow.
Described feature is, interior contact base is provided with twice power spring mounting groove and one fairlead mounting groove, outer contact base is designed with twice power spring mounting groove, the two passes through respective outer side edges, complete the control of axiality, inside and outside power spring homogeneous compaction can be ensured like this, provide reliable big current through-flow.
The beneficial effects of the utility model are: the electrical equipment for ultra high voltage field provides a kind of structure of high throughflow ability, is conducive to the transmission capacity of raising equipment, when transmitting equivalent capability, decrease the electrical equipment investment in ultra high voltage field.
