Embodiment Construction

[0039] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0040] See Figure 1-Figure 13 , a method for installing a booster station of a wind power and photovoltaic power generation system, comprising the following method steps:

[0041] 1) Install the GIS foundation first. The ground bearing capacity of the GIS foundation is not less than 10t. The adjustment method of the foundation height is:

[0042] a) Find out the highest point of the metal embedded parts according to the actual measurement of the base height of each interval, mark the height of this point as "L", adjust the installation base height of the first interval with the gasket, and mark the height of this point as "L" after adjustment '", the adjustment range of the base height of the first interval is L'=L+(5~10)mm;

[0043] b) Based on the actual height of the highest point of the metal embedded part of the first interval foundation a...

Abstract

The invention relates to a method for installing the booster stations for wind power and photovoltaic power generation systems. According to the method, a foundation adjustment method and an initial spacer in-place method are adopted; the highest point of metal embedded parts is found out; an initial spacer installation foundation height is adjusted through gaskets; other spacer foundation heightsare pre-adjusted according to the initial spacer installation foundation height; a bus-bar connection spacer is adopted as an initial spacer to be installed; and after the bus-bar connection spacer is installed, other spacer on two sides of the bus-bar connection spacer are installed. With the method adopted, the accumulated error of the installation of a GIS can be reduced, and the sealing degree of the GIS is ensured; after the spacers are in butt joint with one another, the insertion depths of contacts are calculated; the insertion depths of conductors and contact seats are confirmed, andtherefore, requirements for the sealing degree of the GIS and the safety of a plug are satisfied; the rapid pressing and separation of flanges between the spacers can be facilitated through a multifunctional clamp, and therefore, damage to equipment contacts during the separation of the flanges is avoided; and the multifunctional clamp has a cable shearing function and a cable head crimping function, so that the multifunctional clamp can be used in other electrical construction.

Description

technical field [0001] The invention relates to the construction technology of electric power and metallurgical system substations, in particular to the construction of a core equipment of a step-up station of a wind power generation and photovoltaic power generation system, that is, a step-up transformer and a GIS combined electrical appliance. Background technique [0002] With the development of science and technology, wind power and photovoltaic power generation have gradually become popular. Many rebuilt or newly built booster stations have eliminated the original AIS (open type) structure, and the capacity of transformers has also been increased. The original construction methods can no longer meet the requirements. To meet the needs of modern power development, the installation method of step-up transformers and GIS is a new technology that must be mastered in the modern power installation industry. [0003] In large substations such as 220KV / 66KV, 110KV / 66KV or 66KV / ...
