Description

A kind of I-shaped E-house modular transformer substations

【Technical field】

The utility model is related to the power transmission and transformation devices of electric system, especially with a kind of I-shaped E-house modularizations power transformation It stands related.

【Background technology】

In the layout type of existing substation of China, crisscross layout type, the road in substation are mostly used Around each EM equipment module, therefore in civil engineering, substantially path area occupies the significant proportion of the change station gross area.Together When substation site operation, there are long construction period, human and material resources wastes.Now in an inch of land is an inch of gold city, substation accounts for Ground area size, construction period length etc. are all the factors for causing change station investment construction budget high.

Therefore, in order to solve the above technical problems, it is necessory to change traditional substation's construction with a kind of thinking of innovation, The present inventor proposes a kind of I-shaped E-house (electrical prefabricated) modular transformer substation finally through excessive kind of design and research, To overcome the defect in the prior art.

【Utility model content】

To solve the above problems, the purpose of this utility model is to provide a kind of I-shaped E-house modular transformer substations, The floor space of substation can be reduced, shorten construction period, significantly save the spending of human and material resources, financial resources.

To achieve the above object, the technical solution that the utility model is taken is：

A kind of I-shaped E-house modular transformer substations include the road of I-shaped laying, road centre main road both sides Concave domain forms the device space one and the device space two, the device space one are laid with 110kV high-voltage combined electrical apparatus Power entry modules (1), the device space two is laid with transformer module (2), 10kV combined electrical apparatuses Power entry module (3)；Cloth on the outside of the wing of road both ends If intelligent cabin module (4), station power use system module (5), reactive compensation system module (6).

The station power use system module (5), reactive compensation system module (6) are laid in the outside of the same end wing.

The 110kV high-voltage combined electrical apparatus Power entry module (1) uses combined electrical apparatus HGIS switchgears.

The transformer module (2) uses all-sealed transformer.

The transformer module (2) uses factory presets type.

It is connect using busbar between the transformer module (2) and 10kV combined electrical apparatuses Power entry module (3).

The 10kV combined electrical apparatuses Power entry module (3) is mounted on holder (7), and holder includes stabilizer blade (71), substrate (72)；Stabilizer blade (71) is connect with live civil engineering pedestal, and substrate (72) is laid with the upper end for being fixed on stabilizer blade (71), interior that 10kV groups are housed The nacelle for closing electric appliance Power entry module (3) is erected on substrate (72).

Using cast shielding all insulation busbar connection in the nacelle of the 10kV combined electrical apparatuses Power entry module (3).

Described substrate (72) lower surface is fixed with cable testing bridge.

There are gaps to form electricity between substrate (72) upper surface and the nacelle of 10kV combined electrical apparatuses Power entry module (3) Cable clip layer.

Compared with prior art, the I-shaped E-house modular transformer substations of the utility model have the advantages that：

1, the utility model has broken crisscross traditional substation's layout type in a creative way, by the arrangement of substation Using I-shaped structure, civil engineering floor space significantly reduces, short construction period, while can ensure that road can spread all over substation There is module device.

2, switchgear of prefabrication formula modular transformer substation selects HGIS, and equipment weatherability is high, reliability is high, steady It is qualitative it is good, safeguard less, antidetonation earthquake intensity by 9 grades design, belong to shock resistance product.The substation that secondary device selects state's net to carry out uses Intelligent device, and using wiring before plate, convenient for safeguarding, secondary device is installed in secondary prefabricated cabin, and secondary prefabricated cabin is double-deck Thermal-insulating body structure, and install industrial air-conditioning additional, good heat preservation performance, cold resistance is strong, radioresistance, anti-interference etc.；

3, prefabrication formula modular transformer substation is that Substation Electric Equipment is split into relatively independent multiple function moulds Block completes prepackage, experiment and combined debugging etc. in factory, then by independent each modular transportation to scene, reaches scene respectively Quickly integrate assembling afterwards, debugging cycle shortened within 2 weeks, the construction efficiency of the substation greatlyd improve.

4, by econmics comparison, one second part construction cost of 110kV high pressures is not reduced substantially, but high-voltage switch gear is pacified Whole Transporting and installation in steel platform shorten the construction period at scene；35kV switchgears use outdoor/indoor HGIS, and be assembled into steel platform or on internal container, equipment price is risen, but 35kV switchgear houses are cancelled, whole Body cost is declined；Secondary device uses prefabricated nacelle, and overall cost is risen, but the construction in master control building is omitted, Overall cost lowers significantly.By modularization construction, electrical equipment in-site installation expense is cancelled substantially, has been integrally incorporated in In cost of equipment, operating expenses has been saved.Modularization construction machines ground is small, and field basic operating expenses is reduced.Pass through It calculates, modularization becomes substation and compares on the basis of not considering cost of land, and whole construction cost decreases.

4, prefabrication formula modular transformer substation electrically, is disappeared with reference to national standard, rower and State Grid Corporation of China's standard design Anti-, environmental protection is met the requirements of the standard, it can be ensured that product is smoothly incorporated into the power networks.
