Description

Novel combined box-type transformer

One, technical field

The utility model relates to appliance field, particularly a kind of novel combined box-type transformer.

Two, background technology

World today's power industry high speed development, in the distribution field, combined transformer is little with its volume, simple installation, safe and reliable, advantage such as price is low, is subjected to vast power supply department and user's favor.From the nineties in 20th century American casing transformer introduce China, nearly more than 2000 in more than 50 city of China, more than 70 power supply administration's operation, its operation conditions is good, nearly 10 years of the longest operation.But when breaking down, since the problem that exists on its structure, maintenance difficult, and the expense height can't normally use, even cause some problems in fund and the production.So need develop the corresponding product that is fit to China's actual conditions, promptly novel combined box-type transformer.

Three, utility model content

For overcoming the deficiencies in the prior art, the purpose of the utility model just provides novel combined box-type transformer, can effectively solve maintenance difficult, the problem that expense is high, the technical scheme of its solution is, include transformer and radiator, transformer is equipped with gilled radiator on the adjacent both sides, and high-voltage connection terminal and the low-voltage wiring terminal that joins with transformer arranged in the cabinet of transformer bottom, and high-tension cable inlet wire and high-voltage connection terminal join, low pressure master's inlet wire two ends join with the indoor low pressure outlet of the low-voltage wiring terminal of transformer and low pressure outlet respectively, the low pressure outlet is joined with the capacitive compensator in the cabinet top, the utility model novel structure, simply, effective combination of each parts, easy to use, for ease of maintenaince, expense is low, and is safe and reliable, be inventive improvements and innovation, good economic and social benefit is arranged transformer.

Four, description of drawings

Accompanying drawing is a structural front view of the present utility model.

Five, embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Shown in accompanying drawing, the utility model includes transformer and radiator, transformer is equipped with gilled radiator 2 on the 1 adjacent both sides, the high-voltage connection terminal 4 and the low-voltage wiring terminal 5 that join with transformer are arranged in the cabinet of transformer bottom, high-tension cable inlet wire 13 joins with high-voltage connection terminal 4, low pressure master's inlet wire 12 two ends respectively with low-voltage wiring terminal 5 and low pressure outlet chamber 7 in low pressure outlet 11 join, the low pressure outlet is joined with the capacitive compensator in the cabinet top 10.

For easy to use, said cabinet 8 is the box of height two parts formation, high-voltage connection terminal that the lower part casing is linked to each other by equal altitudes successively and high-tension cable inlet wire store chamber 3, low-voltage wiring terminal and low pressure master inlet wire and store chamber 6 and low pressure outlet and store chamber 7 and forms, and it is that capacitive compensator stores chamber 9 that the high part casing of 7 tops, chamber by transformer 1 stored in the low pressure outlet.

The utility model is existing assembly is carried out the science combination, constitute novel combined box-type transformer, claim common box type " 11 " type terminal (looped network) combined transformer again, filled up domestic blank in this field, promote applying of homemade combined transformer product, change the situation of combined transformer dependence on import in the past.Because this product absorbed advanced foreign technology on stream, thereby dwindle gap with external product, really realized the revolution in distribution field.Simultaneously, also can drive the development of supporting with it associated component industry.Compare with Vintage Product prefabricated substation in the past, combined transformer has following advantage: with the high-pressure side on-load switch, fuse and transformer body are dipped in same fuel tank (showing separately among the figure), make its volume little, compact conformation;

Insulation import terminal and electric cable accessories are adopted in the hyperbaric chamber, install rapidly, flexibly, have a safe and reliable operation characteristic;

Low-pressure side can be installed the low-pressure reactive compensation position as required, and its compensation capacity is generally the 15-35% of transformer capacity, and can realize the Automatic Cycle switching of capacitor according to the variation of inactivity in the electrical network;

Can pass the book interface by GPRS by controller, realize data transmission and the monitoring management function that case is become.

In a word, the utility model is to use the best substitute of box-type substation at present in the 10KV medium voltage network, and is a kind of multifunction environment-protection type highly effective transformer, and cost is low, and dependable performance has remarkable economic efficiency and social benefit.
