Prefabricated adjustable type GIS universal foundation

Abstract

The invention discloses a prefabricated adjustable type GIS universal foundation. A base prefabricated from concrete is included; a left table, a middle table and a right table arranged in parallel are fixedly arranged on the top face of the base; a left groove is formed between the left table and the middle table; a right groove is formed between the middle table and the right table; a pluralityof positioning blocks capable of sliding along the middle table in the left groove and the right groove are further included; steel plate layers capable of being correspondingly welded to the bottom of a GIS are fixedly arranged on the positioning blocks; the positioning blocks are provided with positioning holes arranged in the same direction with the length direction of the middle table; transverse steel ribs are fixedly inserted and installed in the positioning holes; and the two ends of each transverse steel rib are fixedly connected with the two ends of the base. On the premise that a GISconstruction drawing does not exist, construction can be performed, assembling is easy and fast, construction is convenient, the period is short, installation is firm and reliable, after the GIS arrives, the structure can be adjusted to adapt to requirements of the GIS in different sizes, the installing success rate is extremely high, and the prefabricated adjustable type GIS universal foundationis especially suitable for field emergency construction or emergency repair.

Description

technical field [0001] The invention relates to a prefabricated adjustable GIS universal foundation. Background technique [0002] GIS (Gas Insulated Substation) is the abbreviation of the English name of gas insulated substation. In a gas-insulated substation, most of the electrical equipment is directly or indirectly sealed in a pipe tree composed of metal pipes and casings, and no switches, lines and terminals can be seen from the outside. The interior of the pipeline tree uses SF6 gas as the insulating medium, and all high-voltage electrical components are sealed in grounded metal cylinders. It is a high-voltage power distribution device composed of seven high-voltage electrical appliances including circuit breaker, bus bar, disconnector, voltage transformer, current transformer, lightning arrester and bushing. [0003] GIS has the advantages of stable and reliable operation and low maintenance rate, so it is widely used in the current power supply. However, GIS has al...

Problems solved by technology

[0003] GIS has the advantages of stable and reliable operation and low maintenance rate, so it is widely used in the current power supply. However, GIS has always had the disadvantage of long construction period during installation and commissioning, which has brought obstacles to the promotion and application of GIS.

At present, the traditional GIS installation method is to wait for the manufacturer to provide the information, draw the reserved embedded map according to the manufacturer's information, then cast the foundation on site, maintain it for 28 days, wait for the foundation to solidify, and install the GIS equipment. Therefore, the construction period is very long, which seriously affects the performance of GIS. Commissioning
