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 electrical switchgear technical field.
Background technology
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 suspension tubular busbar.
When intelligent substation design, 220kV power distribution equipment can adopt conventional current instrument transformer and electronic mutual inductor, GIS power distribution equipment, HGIS power distribution equipment and potting breaker power distribution equipment, because circuit breaker summation current transformer is the integrated design, adopt conventional current instrument transformer or electronic mutual inductor less on the longitudinal size impact of power distribution equipment.
Fig. 1, shown in 2, State Grid Corporation of China's promulgation " the project of transmitting and converting electricity universal design 110(66 of State Grid Corporation of China) ~ 750kV intelligent substation part " in, when typical 220kV porcelain knob breaker (AIS) power distribution equipment adopts electronic mutual inductor, select current/voltage combined instrument transformer 3, current/voltage combined instrument transformer 3 is installed with 4 combinations of outlet isolating switch, special maintaining roadway 6 is set between circuit breaker 5 and outlet isolating switch 4, power distribution equipment longitudinal size is compared and is adopted the minimizing of conventional current instrument transformer limited, main transformer cross-line 7 is still longer, transition framework 8 need be set, power distribution equipment is brought into play the advantage that adopts current/voltage combined instrument transformer not yet completely, bus equipment adopts the single-pole vertical isolating switch 9 of arranged crosswise, and floor space is large.
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 of the intelligent substation that can give full play to current/voltage combined instrument transformer advantage is provided.
The object of the invention is to complete by following technical solution, described arrangement is: it adopts current/voltage combined instrument transformer, described current/voltage combined instrument transformer and the combination of outlet isolating switch are installed, cancel the special maintaining roadway of circuit breaker and outlet isolating switch, and described main transformer cross-line is not established transition framework; Adopt the medium-sized layout of suspension tubular busbar, between every two suspension tubular busbars, establish a local overhauling road.
Described local overhauling road is arranged under bus, and bus equipment is arranged in end of bus bars, and the single-pole vertical isolating switch that adopts a word to arrange.
The invention belongs to the one improvement to prior art, it has connection and reasonable arrangement, can effectively save floor occupying area and reduce investment, reduces the features such as use cost.
