Description
Technical field
The utility model relates to electric power Medium Voltage Switchgear technical field, relates in particular to solid insulation switch cabinet.
Background technology
Medium-voltage distribution equipment is the infrastructure device that involves a wide range of knowledge in the network system.Because use amount is very big, and links up user's bridge as main electrical network in network system, therefore, its technology trends also allows user and manufacturing enterprise very pay close attention to.Because the rapid growth of the newly-increased installation of electric power year and technological updating of enterprises has driven the quick dilatation in switch market, industry income from sales and the major product output of being added up by the industry yearbook all increased with 20%～30% speed every year in recent years, and market is burning hot.The market of equipment for power transmission and distribution and Medium voltage switch or circuit breaker mainly is made of four aspects, and namely adding new capacity needs corollary equipment electrical network year; Each department of national economy equipment; Technological transformation needs; Outlet device.
At first important factor is that each department of national economy is subjected to electricity and part power consumption equipment (also comprising low voltage switchgear) from electrical network, general user's terminal grid equipment mainly is middle pressure (6KV, 10KV, 20KV, 35KV, 66KV), and 80%～85% of medium voltage switchgear equipment and box-type substation sold the non-electricity system user.Next is that technological transformation needs equipment, 20～30 years useful life of switchgear and box-type substation, general transformer station will change new equipment after 15 years, along with net capacity increases, rated current and rated short circuit current constantly rise, original switchgear has been difficult to be competent at, needs the more more equipment of high parameter of new capability.China " 95 " beginning upgrading urban and rural power grids engineering will promote the equipment for power transmission and distribution technical merit exactly, occupies larger specific gravity in its market capacity of fixing the date.The 3rd market is outlet.
It is still very low at present that China has electric level per capita.Along with expanding economy, growth in the living standard faces the restriction of power shortage.Present some economic hot spots areas, such as Yangtze River Delta, the Delta of the Pearl River, Beijing-Tianjin area peak times of power consumption in summer, outside input electricity is many, and some are local such as the power failure of often operating a switch of Wenzhou Area enterprise in Zhejiang.China's electrical network distribution ability lags behind still unresolved.Over more than 50 year, " retransmit, gently supply, don't work " policy is in persistent pursuit of in China's power construction, and power distribution network distribution ability lags behind, and can not just can reverse through the 3-5 upgrading urban and rural power grids.Therefore, national economy department arranges still to plan to drop into the upgrading urban and rural power grids expense during " 12 ", and expense still can reach " 15 " level.Power grid construction is national proactive fiscal policy part, and proactive fiscal policy is expanded domestic demand and is not only the thing in 3 or five years, but the longtime policy of decades.
The SF6 switch of extensive use in the present distribution system, its product is widely used in the urban distribution network because volume is little, full-insulated full-sealed.China does not adopt in developed country medium-voltage distribution fields such as America and Europes as the Inflatable ring main unit of dielectric with SF6, and the 10KV product is applied as the master with vacuum switch, and hexafluoride gas switch only just can be used in superhigh pressure.This mainly is because SF6 gas is one of greenhouse gas of generally acknowledging in the switch, its greenhouse effect are 2500 times of CO2 gas, the survival life-span in atmosphere is 3400, and can produce the toxic gas fluoride under the high pressure arc extinguishing, also can form acid rain at malaria simultaneously.And all there is the Leakage Gas problem in the 10KV SF6 product of our practical application, has increased the weight of the maintenance of electric power system, and reclaims very difficult.
The power switch of current use and switch cubicle volume matching used with it are comparatively bigger than normal, and use in a large number SF6 gas, bring serious pollution to environment, with regard to poor expandability of power switch itself, install also inconvenient, sometimes because of the restriction of installation site, the actual installation of power switch and switch cubicle or replacing have certain difficulty, and because the factors such as insulation property, Material texture, environment for use make the reliability of power switch and switch cubicle relatively poor, thereby manufacturing cost and operation expense are increased greatly.
