Abstract
The invention relates to a preinstall transformer station, and relative production. Wherein, it comprises transformer unit, high voltage unit and low voltage unit; and it is characterized in said three parts form insulated modular structure; the high-voltage unit contains protected fusion device, load switch, and auxiliary device; the insulated mediums in transformer unit and high-voltage unit both use transformer oil; the invention separates the oil tank of high-voltage unit and the oil tank of transformer to avoid carbonizing oil in arc process in the load switch operation, which will decrease the insulated property. And the modular structure can convert the high-voltage unit with SF6 annular network, to obtain low cost.
Description
Technical field
The present invention relates to a kind of change power distribution equipment, especially refer to a kind of preassembled transformer station and manufacture method of modular construction.
Technical background
In order to make combined transformer (being called for short case becomes) compact overall structure, usually combined transformer is placed on transformer body, high voltage load switch, fuse and high-low pressure line in the hermetic fuel tank, adopts transformer oil and dielectric over the ground alternate as live part.
But the electric arc that above-mentioned on-load switch frequent operation is produced will make rotten, the carbonization of transformer oil, influence its insulation property, thereby reduce the transformer reliability of operation.
In addition, to build collection high-voltage switch gear, transformer, the low tension switch that needs grow up be the complete change power distribution equipment of one in order to satisfy city net, it is preassembled transformer station, it can be used for the looped network distribution system, can be used as the power supply of emanant electric network terminal again, advantages such as, easy maintenance reliable with it, compact conformation, conveniently moving are applicable to that urban skyscraper, residential quarters, public place and provisional equipment etc. become the distribution place.
But, realize the requirement that combined transformer and preassembled transformer station exchange as lotus, be the problem that presses for solution at present in the industry.
Summary of the invention
The present invention aims to provide a kind of preassembled transformer station and manufacture method of modular construction, its arcing that both can avoid on-load switch to be produced in operating process makes the transformer oil carbonization and the generation of the complete machine decreasing insulating phenomenon that causes, and can make the transition easily when the remodeling demand again is the structure of preassembled transformer station.
The preassembled transformer station of a kind of modular construction provided by the present invention; comprise transformer unit, high voltage unit and low voltage unit; it is characterized in that: the three forms the modular construction of mutual isolation; and also install fuse, on-load switch and the corresponding auxiliary equipment of protection in high voltage unit concentratedly, again: the dielectric in described transformer unit, the high voltage unit all adopts transformer oil.
In the preassembled transformer station of above-mentioned modular construction, transformer unit, high voltage unit and low voltage unit three form integral body and be " product " font layout, and the casing of independent sealing is all arranged, and be promptly separable after the dismounting.
In the preassembled transformer station of above-mentioned modular construction, high voltage unit can be the SF6 ring main unit.
The manufacture method of the preassembled transformer station of a kind of modular construction that the present invention also provides, comprise the following steps: transformer unit, high voltage unit and the low voltage unit of routine are made independently module of standard respectively, wherein: the switch casing of high voltage unit separates with the fuel tank of transformer unit; Make one ccontaining and isolate the respective housings of described transformer unit, high voltage unit and low voltage unit; Each module is assembled by standard; The dielectric of filling, i.e. transformer oil in the fuel tank of the switch casing of high voltage unit and transformer unit; High voltage unit and low voltage unit are carried out the inside and outside debugging that is connected; At last this preassembled transformer station is carried out system debug.
Adopted above-mentioned technical solution, the fuel tank that is about to high voltage unit separates with transformer body fuel tank, can prevent from like this to make oil carbonization after the arcing in the on-load switch operating process, thereby cause the complete machine decreasing insulating.In addition, modular construction of the present invention can be exchanged high voltage unit and SF6 ring main unit, is the structure of preassembled transformer station thereby make the transition with cheap cost, to satisfy the demand that the user uses.
