Transformer station main transformer low tension side field and deploying method thereof

Abstract

The invention discloses a transformer station main transformer low tension side field and a deploying method thereof; a GIB bus is set in a concavoconvex bending structure in the horizontal direction so as to form a plurality of gapped buses opening to two sides and arranged in a staggering manner; the GIB bus is attached to the ground low position in the vertical direction; a plurality of reactive compensations are arranged on two sides of the GIB bus at intervals, and respectively electrically connected with the corresponding gapped buses; in the horizontal direction, the gapped bus transverse size is determined in the following steps: using the maximum distance between the same device in the reactive compensation interval and the gapped bus as the transverse size of the gapped bus; the vertical size is determined by the following steps: when the transverse size is known, the gapped bus vertical size is equal to or bigger than the minimum vertical size when the safety distance requirements of all equipment normal operation or maintenance and the minimum distance requirements in equipment transportations are simultaneously met. The transformer station main transformer low tension side field deploying method can flexibly arrange equipment, thus saving occupation area and space.

Description

technical field [0001] The invention belongs to the technical field of power system power transmission and transformation engineering design, and in particular relates to a substation main transformer low-voltage side site and an arrangement method thereof. Background technique [0002] Such as figure 1 and 2 As shown, at present, the main transformer low-voltage side busbar in domestic outdoor substations mainly adopts outdoor supporting tube busbar, and the main transformer, reactive power compensation device and both sides of the tube busbar are connected by bare wires. , and a certain distance between the lead wire and the support insulator of the pipe mother. Switching equipment such as HGIS and AIS equipment should generally be placed outside the projection range of the busbar, which limits the distance between the main transformer, the main busbar and each interval equipment. The flexibility of relative positioning restricts the overall layout optimization of the lo...

Problems solved by technology

[0006] To sum up, although the use of GIB bus in the traditional scheme reduces the site and lateral size to a certain extent, the utilization rate of the reactive power compensation site is still low
