Abstract

The utility model relates to an integrated transformer substation of half open -type of 110kV. Be the road around the cement foundation, the road has the guardrail outward, the last fixed prefabricated storehouse of cement foundation, no. I transformer, no. II transformers, no. I grounding transformer, no. II grounding transformer, and no. I reducing transformer and no. II reducing transformer, no. I transformer, no. II transformers, no. I grounding transformer, no. II grounding transformer, no. I reducing transformer and no. II reducing transformer outdoor arrangement, prefabricated storehouse in configuration primary equipment and secondary protect supervisory equipment. Its structure is simpler, and the cost is cheaper, and indoor outdoor power equipment can carry out the construction operation in step, and construction period is shorter.

Description

110kV semi-open-type integrated transformer substation

Technical field

The utility model belongs to a kind of transformer station, particularly a kind of integrated transformer substation of 110kV semi-open-type.

Background technology

Existing integrated power transformation adopts totally-enclosed metal framework structures, and all power equipments are enclosed in a bulk metal frame structure inner, cost compare is high, and difficulty of construction and construction period are relatively long.

Summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides a kind of 110kV semi-open-type integrated transformer substation.Its structure is more simple, and cost is cheaper, and power equipment synchronously can carry out construction operation indoor and outdoor, and the construction period is shorter.

The technical scheme in the invention for solving the technical problem is: the surrounding of concrete pedestal is road, guardrail is had outside road, concrete pedestal is fixed prefabricated storehouse, No. I transformer, No. II transformer, No. I grounding transformer, No. II ground connection become transformer, No. I step-down transformer and No. II step-down transformer, No. I described transformer, No. II transformer, No. I grounding transformer, No. II ground connection become transformer, No. I step-down transformer and No. II outdoor layout of step-down transformer; Primary equipment and second protection watch-dog is configured in described prefabricated storehouse.

The utility model has following advantages: 1), by equipment component carry out outdoor placement, only by the primary equipments such as main switch and second protection watch-dog, be placed on the prefabricated storehouse of totally-enclosed metal framework structure inner, its structure is simpler, cost is cheaper, equipment can carry out construction operation simultaneously indoor and outdoor, and the construction period is shorter; 2), its main frame structure adopt integrated hanging arrange, bottom be mainly used in line cable arrangements and bottom ventilation heat radiation; 3), main frame structure and connecting bolt all adopt hot dip galvanizing process process, ensures 30 year useful life; 4), main frame structure be all bolt connect, facilitate assembled in situ, and be optimized layout according to load-bearing and support, ensure enough seismic behavior.

Embodiment

As shown in Figure 1, the surrounding of concrete pedestal 3 is road 4, guardrail 1 is had outside road 4, concrete pedestal 3 is fixed No. 10, I, prefabricated storehouse transformer 8, No. II transformer 9, No. I grounding transformer 6, No. II ground connection and become transformer 7, No. I step-down transformer 2 and No. II step-down transformer 5, No. I described transformer 8, No. II transformer 9, No. I grounding transformer 6, No. II ground connection becomes transformer 7, No. I step-down transformer 2 and No. II outdoor layout of step-down transformer 5; Configuration primary equipment and second protection watch-dog in described prefabricated storehouse 10.

Have two-layer in described prefabricated storehouse 10, the primary equipment described in one deck layout, primary equipment comprises 35kV/10kV switch cubicle 14 and static reactive generator SVG group cabinet 13; Second protection watch-dog described in one deck layout, second protection watch-dog comprises sulfur hexafluoride combined electric appliance GIS12 and PK-10 protection screen 16.

Described PK-10 protection screen 16 is arranged in protection room 11, separates with described sulfur hexafluoride combined electric appliance GIS12.

Described prefabricated storehouse 10 is bulk metal frame structure, the unsettled layout of one deck, and bottom is mainly used in line cable arrangements and bottom equipment ventilation and heat.All metal frameworks and connecting bolt all adopt hot dip galvanizing process process, ensure 30 years design service lifes.Main body frame is all with bolts facilitates assembled in situ, and frame structure internal electric equipment is optimized layout according to load-bearing and support, ensures enough seismic behavior.

The utility model is applicable to electric power system at urban distribution network, rural power grids, and photovoltaic generation, wind power generation, water generating etc. are newly-built, transformation and Transfomer Substation Reconstruction engineering.
