Product synopsis:
Combined transformer (also called American box change, the following are referred to as American box variable) is to transformer implement body, high-voltage switch, protection devices such as unified design with fuse, put in same seal tank and therefore less massive. American box variable can be used not only to outdoor, and can be used in indoor, widely used in industrial park, dweller, commercial center and high-rise building etc various places.
Product features:
Second-ranking functional, reliable
Cutting load current, can carry out a full range of current protection, a ring network (including dual-supply) and terminal two kinds of power-supply modes available, has the basic function of transformer substation.
Lack of investment and the second-ranking occupies a small area, easy installation, quick effect
Save money: better than Europe type box variable or distribution variable + distribution both less capital investment;
Land-saving: small volume, which is about change with capacity of Europe type box 1/3, volume change + substations volume distribution 1/5;
Save time: easy installation, the scene just tighten bolts and four installation connected into cable take-off can;
Energy: users don't need to undertake short-circuit current, dynamic thermal stability, relay protection multifarious design calculation, the box-type convering stations can only determine the capacity of transformer order.
Second-ranking good safety
Adopt totally closed design, product shell grounding, outside surface without any conductive parts, so that no insulation distance is safe, reliable guarantee for high voltage into line adopts full insulation elbow shape cable outlet, inserted convenient, outside surface not charged, can be directly touch; By insulation lever operation, more sure any personal safety; Using security structure design, can prevent innocently and malicious removal.
Second-ranking simple maintenance
Plug type recuperators fuse and cable plug structure make replacement very convenient; Fully seal design of transformer oil with air to transformer no contact transformer free maintenance.
Second-ranking, weathering good high protection grade
Hv switchgear and transformer implement body on the same note oil box, adopts the whole sealing structure, antifouling force strong, make American box change applies to mining, desert, desert, plateau, etc. Various kinds of weather of places.
Second-ranking low noise environmental
My company applied for many years in dry type transformer noise research a disruptive technology achievements, developing the core structure, low noise reached the city residents living community requirements by the noise level, user's consistent high praise.
Second-ranking percolationless
My company American box becomes production adopts the advanced foreign technology and product manufactured before all needs to inherit 50kpa tank sealing test no leakage.
Second-ranking insulation high strength
Domestic use of 110 kv transformer industry products that USES vacuum drying and vacuum note oil craft, product insulation to a new level. Each machine factory in all American box change in the low-pressure copper foil experiment increased pressure, impact test by applying strict inspection technology control product quality.
Second-ranking weatherability are excellent
Using uv topcoats, shell according to strict ANSI standard, outdoor weathering capabilities can handle more than a decade.
Second-ranking product solutions is rich, flexible configuration
Structure: my company according to the user's demand, the development of the product font, font, L, eyes of high pressure measuring American box variable structure.
Electrical plan: high voltage circuit has single terminal, the ring net, double power supply, configuration, and can be equipped with high pressure measuring, additional, still can add lightning arrester, charged displays, short-circuit fault indicator and so on many kinds of no one. Low voltage configuration can be installed power metering, reactive compensation, much return branch outlet, phase lack protection, even the remote communication and so on many functions. Numerous functional configuration can be comprehensively to meet user needs.
Appearance plan: can according to customer request design, delicate, concise appearance design, new style, modern style, coordinated with the surrounding environment.
The product model meaning:
