Abstract
The invention discloses a method for arranging an air insulated switchgear (AIS) power distribution unit of a smart substation. In the arrangement method, combined current and voltage transformers are adopted, and are arranged in combination with outlet isolating switches, a dedicated maintenance path for air insulated switchgears and the outlet isolating switches are eliminated, and main transformation jumper wires are not provided with transitional frameworks; a medium-profile layout is formed by suspended tubular busbars, and local maintenance paths are arranged between every two adjacent suspended tubular busbars; and the local maintenance paths are arranged below the busbars, busbar equipment is arranged on the end parts of the busbars, and lined-up single-column vertical isolating switches are adopted. The invention has the characteristics that: the method is rational in arrangement; an occupied area can be effectively saved; investment can be decreased; use cost can be decreased; and the like.
Description
Technical field
What the present invention relates to is a kind of 220kV porcelain knob breaker (AIS) power distribution equipment of intelligent substation, belongs to the electrical switchgear technical field.
Background technology
The 220kV power distribution equipment mainly contains four kinds of forms: GIS power distribution equipment, HGIS power distribution equipment, porcelain knob breaker (AIS) power distribution equipment and potting breaker power distribution equipment.Porcelain knob breaker (AIS) power distribution equipment mainly adopts to be supported or the medium-sized layout of column pipe bus.
During the intelligent substation design; The 220kV power distribution equipment can adopt conventional current instrument transformer and electronic mutual inductor; The GIS power distribution equipment; HGIS power distribution equipment and potting breaker power distribution equipment adopt conventional current instrument transformer or electronic mutual inductor less to the longitudinal size influence of power distribution equipment because the circuit breaker summation current transformer is the integrated design.
Fig. 1, shown in 2; In " State Grid Corporation of China's project of transmitting and converting electricity universal design 110 (66) ~ 750kV intelligent substation parts " of State Grid Corporation of China's promulgation, when typical 220kV porcelain knob breaker (AIS) power distribution equipment adopts electronic mutual inductor, select current/voltage combined instrument transformer 3 for use; Current/voltage combined instrument transformer 3 and 4 aggregate erections of outlet isolating switch; Special-purpose maintaining roadway 6 is set between circuit breaker 5 and the outlet isolating switch 4, and the power distribution equipment longitudinal size is compared and is adopted the minimizing of conventional current instrument transformer limited, and main transformer cross-line 7 is still longer; Transition framework 8 need be set, and power distribution equipment is not brought into play the advantage that adopts the current/voltage combined instrument transformer as yet fully; Bus equipment adopts the single-column vertical isolation switch 9 of arranged crosswise, and floor space is big.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of AIS power distribution equipment method for arranging that can give full play to the intelligent substation of current/voltage combined instrument transformer advantage is provided.
The objective of the invention is to accomplish through following technical scheme; Described arrangement is: it adopts the current/voltage combined instrument transformer; Said current/voltage combined instrument transformer and the aggregate erection of outlet isolating switch; The special-purpose maintaining roadway of cancellation circuit breaker and outlet isolating switch, and said main transformer cross-line is not established the transition framework; Adopt the medium-sized layout of column pipe bus, establish a local overhauling road between per two column pipe buses.
Described local overhauling road is arranged under the bus, and bus equipment is arranged in the bus end, and the single-column vertical isolation switch that adopts a word to arrange.
The invention belongs to a kind of improvement to prior art, it has connection and reasonable arrangement, can effectively save floor occupying area and reduce investment, reduces characteristics such as use cost.
