Description
Technical field
The utility model relates to a kind of transformer station, particularly a kind of box-type substation.
Background technology
Box-type substation (abbreviate as case become) be a kind of prefabrication that high voltage switchgear, distribution transformer and low-voltage distribution equipment are lined up one by certain connection plan indoor/outdoor close-coupled controller switching equipment, realize functions such as high powered, transformer step-down, low-voltage distribution.Box-type substation be arranged at protection against the tide, antirust, dustproof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, movably in the steel construction casing, electromechanical integration, totally-enclosed operation is specially adapted to city net construction and upgrading, is a kind of brand-new transformer station that emerges after civil engineering transformer station.
Existing box-type substation is according to the difference of product structure difference and employing components and parts, be divided into European case change and American case and become two big classes, the characteristics that this two big class box-type substation is had nothing in common with each other, but structurally all form by high voltage switchgear, distribution transformer and low-voltage distribution equipment three parts.
European case becomes employing high and low pressure switch cubicle, and transformer is formed mode.As shown in Figure 1, its design feature is: the device of high voltage switchgear 64, distribution transformer 63 and low-voltage distribution equipment 61 3 parts installs respectively in three different compartments, and is independent mutually on the layout of position; Realize being electrically connected by low-voltage cable 62 between distribution transformer 63 and the low-voltage distribution equipment 61, realize being electrically connected by high-tension cable 65 between high voltage switchgear 64 and the distribution transformer 63; Not sealing between the high-pressure side outlet of transformer and the stube cable; And mutual high voltage switchgear part relatively independent on arranging, distribution transformer part and low-voltage distribution equipment are partly wired up with a big outdoor case.
Above-mentioned European case becomes the weak point that exists and is: because European case becomes inner ordinary tap cabinet and the transformer installed, small product size is bigger, and cost is than higher.Because not sealing between the high-pressure side outlet of transformer and the stube cable, thus anti-water, anti-flood capacity a little less than.
It is a kind of package that grows up on the basis of transformer that American case becomes, and is oil immersion to be sealed worker's distribution transformer and the high and low voltage electrical equipment element makes up.As shown in Figure 2, its design feature is: the layout first line of a couplet of device in the position of high voltage switchgear 75, distribution transformer 77 and low-voltage distribution equipment 72 3 parts is one; Binding post 74 complete UNICOMs are passed through in inside between high voltage switchgear 75 and distribution transformer 77, sometimes, also have been full of mobile medium 76 in this UNICOM's part; The transformer that American case becomes directly is exposed to the open air, mainly is to utilize transformer oil to cool off, and insulation and heat radiation, also are the important channels of transformer heat radiation at the fin of transformer; The on-load switch that cut-offs transformer places in the transformer, and the low-voltage side outlet of transformer directly links to each other with the leading-out terminal of on-load switch, and the end of incoming cables of on-load switch then is connected with American cased well on the wall box; The low pressure outlet also places on the tank wall, and low-voltage side outlet is directly linked to each other with low-voltage cabinet, and the connection distance of low-pressure side busbar 71 is also shortened greatly; And American case becomes whole and is set to a metal architecture that joins together, does not have the similar house of tangible profile parcel shell.These design features make volume that American case becomes only into the European case variable volume of capacity 2/3rds in addition littler.
The weak point that above-mentioned American case becomes is: because on-load switch, fuse and transformer core, coil are all in a casing, with common insulation and the coolant of transformer oil as them, and the cut-offfing of on-load switch, fuse are met short circuit current and the process that fuses, to inevitably produce electric arc, make transformer oil carbonization, free, cause the transformer oil accelerated ageing, insulation is reduced.The electric parameter of high-voltage board part is lower, such as, heat-stable current is general only to 16kA, 2S; Usually the available cabinet type of high-voltage board part has only on-load switch and combined electrical apparatus (and the variation that puts in order is also few), does not have the circuit breaker Scheme Selection basically, increases also more complicated of metering units.Because high pressure, transformer, low pressure three parts join together and can't split, can't upgrade, and the part of devices damage is integral replacing basically.
