As can be seen here, country will promote one's own profession science, rule to the encouragement of power transmission and distribution control equipment manufacture industry with support policy
The sustainable development of model.
At present, China's actual conditions are had a large population and a few land, and averagely take up an area 7.21m2Box-type substation to the most close-packed China
It is difficult to for business district bear.Town and country modernization construction progress faster, traditional box-type substation is straggly to be squeezed disorderly
Account for the gold ground in downtown area, seem incompatible with graceful urban environment, according to Urban ecological design theory, buried
A kind of electric power complete set of equipments that formula transformer is contemplated to meet the requirement in above-mentioned field and designs and develops.
Current Covered transformer has two kinds of frame modes, and one is European, and it is to use epoxy resin as insulation
Material, products characteristics is easy for installation, hole of directly cutting the earth, and fills again, but capacity is the least, typically after connection line
Less than 100KVA, it is only confined in street lighting.Another kind is American, also known as underground transformer, domestic this
Plant and the compact converting equipment that transformer, high voltage load switch, fuse etc. are positioned in fuel tank is referred to as underground type group
Close transformer.It is arranged in melt pit, is not take up spatial surface, and can within a period of time fortune submerged in water
OK, its distribution system widely used in being big and medium-sized cities, America.The New York of the U.S., Chicago, Canadian temperature brother
The flourishing big city of the ans inch of land is an inch of gold such as China, Toronto all uses Covered transformer mainly setting as 10KVA distribution
Standby.
And the multiplex oil-filled transformer of Covered transformer being widely used at present, the shell by oil-filled transformer reaches
To antiseep, waterproof purpose, but a few class problems below all existing in actual motion: a lot of Covered transformers
High pressure connected mode use the most European or American outdoor cable branch box in the separable connector (plug that uses
Head) connect, sealing is not enough；The casing of most of Covered transformers not through special soda acid PROCESS FOR TREATMENT,
Not possessing long-play in the wet environment of underground, cabinet shell can be corroded, thus causes operation power safety hidden
Suffer from；A lot of Covered transformers self do not have underground operation function, can only rely on the lid of ground, basis, melt pit
Plate is hermetically sealed next waterproof and dampproof, and once cover plate is destroyed, and has water or moisture to immerse and just causes operation power safety the most hidden
Suffer from；The pulsating pump that the running of a lot of Covered transformers relies on ground, basis, melt pit corner built-in carrys out draining, once
Run into the big yield situations such as heavy rain and pour into underground foundation, just lose Excretion, thus cause transformer to run safety
Hidden danger；The high pressure connected mode of a lot of Covered transformers uses the traditional silicon rubber mode that is flexible coupling exposed in melt pit,
Can not effectively prevent the destruction of toy and mechanical external force, thus increase operation power potential safety hazard.
For present case, city illumination mainly has bench type transformer, Europe to become, U.S. becomes and conventional boxes change etc. is joined
Electricity equipment, and along with the development of urban construction and increasing of oil lamp number, the quantity of these equipment is also constantly increasing
Add.From the point of view of service condition in recent years, it is seen that the controller switching equipments such as conventional boxes change have be easy to Maintenance and Repair, can
High, more stable by property, load adjustment easily operates, sealing is relatively strong, safety in operation is higher and running environment relatively
The feature such as good.But, along with more and more higher, as one of urban infrastructure to urban environment and vivid requirement
It is the most obvious that conventional boxes becomes the problem come out in the running of some areas: takes up an area space relatively greatly, ties up prosperity
The narrow space in area；Equipment is destroyed by pilferage easily more than ground；Easily become small advertisement carrier, become and affect city
The vision " pollution sources " of city's environment.Therefore, in urban construction, conventional boxes become the most do not adapt to social development and
Urban environmental protection demand, this is in the urgent need to a kind of novel street lamp controller switching equipment.
