Description
One, technical field
The utility model is the outdoor high-voltage open combined electri cappliance that a kind of power transmission and transformation station is used.
Two, background technology
Along with China's rapid economic development, the demand of electric power and power station power grid construction scale also enlarge day by day.But the contradiction to resource requirement and protection is increasing, and is especially in recent years, more and more higher to the cry of protection of resources.And power transmission and transformation station is in the past built, and power equipment is scattered, and floor space is big, and the land resource waste is serious, power transmission and transformation station overall appearance degree is relatively poor, and the power equipment management difficulty is defeated greatly, transformer station's capacity-increasing transformation difficulty, construction period is long, and the subsidiary control loop dispersion, and reliability is not high.
Three, summary of the invention
The purpose of this utility model is to provide a kind of outdoor high-voltage open combined electri cappliance for the power transmission and transformation station; improve the fail safe and the reliability at power transmission and transformation station; change traditional electric equipment arrangement; reduce floor space; save land resource, reduce the application of highly energy-consuming material and greenhouse gas, utilize resource rationally and effectively; protection environment, thereby the whole synthesis benefit and the social benefit of raising product.
For achieving the above object; the technical scheme that the utility model is taked is: made up by functional units such as circuit breaker, isolating switch, earthed switch, voltage transformer, current transformer, lightning arresters; be fixed on dismountable sectional shelf-unit by machinery and electrical interlocks, form four kinds of basic isolation: pass in and out line interval, female connection interval, main transformer interval, protect at interval.Circuit breaker is a potting breaker, and isolating switch is the compound inslation isolating switch.
The turnover line is spaced apart the circuit breaker both sides respectively one group of isolating switch, adds 1 winding ground switch in addition in the isolating switch outside of advancing (going out) line side, and current transformer is contained on the circuit breaker.The control of advancing (going out) line, measurement and the defencive function at power transmission and transformation station can be realized in this interval.
Female connection is spaced apart the circuit breaker both sides respectively 1 group of isolating switch, and current transformer is contained on the circuit breaker.Bus section control, measurement and the defencive function of transformer station can be realized in this interval.
More than three kinds of intervals all adopt sectional shelf-unit, sectional shelf-unit is made up of circuit breaker cradle and one to two isolation mount.When breaker body breaks down, breaker body can be fallen, on the spot or transport maintenance.
Main transformer is spaced apart circuit breaker has 1 group of isolating switch with respect to a side of main transformer, and current transformer is contained on the circuit breaker.As required, can add 1 winding ground switch in the isolating switch outside in addition.This interval can realize that transformer advances (going out) line traffic control, measurement and protection.
It is 1 group of isolating switch by the self-supporting bus bar side at interval that protection is spaced apart this, and the back is followed successively by 1 winding ground switch, 1 group of lightning arrester, 1 group of voltage transformer, is arranged in jointly on the support.Functions such as lightning-arrest, the voltage monitoring at power transmission and transformation station can be realized in this interval, and can separate realization separately from the bus and safeguard on the spot.
Because the utility model with each main power transmission and transforming equipment centralized arrangement together, as required, form various typical cases interval (pass in and out line interval, female connection interval, main transformer interval, protect at interval), just can adopt the self-supporting bus, dwindled floor space greatly, improved the utilance of land resource, shortened the construction installation period at power transmission and transformation stations, made the external body in power station more attractive in appearance; This combined electrical apparatus can be realized machinery and electrical interlocks easily, but the subsidiary loop centralized arrangement, and the probability that control loop is disturbed has reduced to strengthen the reliability of power system operation; The centralized arrangement of each electric equipment makes plant maintenance and management convenient; Isolating switch, circuit breaker all can adopt motor drive mechanism, can realize power transmission and transformation station unattended duty; In whole project of transmitting and converting electricity, greenhouse gas SF6, non-ferrous metal do not increase, and have reduced the application of high energy consumption materials such as all kinds of porcelain vases, cement.Therefore; the utlity model has the fail safe and the reliability that have improved the power transmission and transformation stations; change traditional electric equipment arrangement; reduce floor space; save land resource, reduce the application of highly energy-consuming material and greenhouse gas, utilize resource rationally and effectively; protection environment, thereby characteristics such as the whole synthesis benefit of raising product and social benefit.
