Description
Technical field
The utility model belongs in the ultra-high voltage transformer station, the arrangement of main transformer inlet wire, relate on the main transformer 1000kV inlet wire with lightning arrester, voltage transformer, a kind of arrangement of GIS sleeve pipe.
Background technology
Main transformer is the core of transformer station, mainly plays conversion voltage, transmission of electric energy.Lead-in wire mode at 1000kV side inlet wire, the built on stilts two division flexible conductors of conventional employing connect, as shown in Figure 1, connect by built on stilts two division flexible conductors 9 between the equipment such as the lightning arrester 4 of the 1000kV side inlet wire of extra-high voltage transformer 1, voltage transformer 5, vertically be arranged in the main transformer side; From main transformer framework 13 built on stilts transition frameworks 10 to power distribution equipment, and then be forwarded to the GIS sleeve pipe.This place's electric field strength is more concentrated, and corona is more serious, and noise is bigger.
Apparatus arrangement such as the lightning arrester of extra-high voltage transformer 1000kV side inlet wire, voltage transformer make the transportation inconvenience of main transformer in the main transformer side, and the power distribution equipment side has a lot of vacant lots to utilize again simultaneously.Simultaneously, transition framework 10 rolled steel dosage are big.
Summary of the invention
The purpose of this utility model is to provide a kind of ultra high voltage main transformer inlet wire to support tube type bus to draw and connects and inlet wire apparatus arrangement structure, realizes reducing the transition framework, reduces corona and noise.
The technical solution of the utility model is: ultra high voltage main transformer inlet wire is supported tube type bus to draw to connect and inlet wire apparatus arrangement structure, it comprises main transformer, lightning arrester, voltage transformer, GIS sleeve pipe, it also comprises first post insulator of main transformer end and second post insulator of inlet wire equipment end; Connect tube type bus between the top of second post insulator, lightning arrester, voltage transformer and GIS sleeve pipe; First post insulator is connected tube type bus with the top of main transformer; First post insulator is connected tube type bus with the second post insulator top.Second post insulator, lightning arrester, voltage transformer and GIS sleeve pipe are arranged in GIS main bus bar side.
Described second post insulator, lightning arrester, voltage transformer and GIS sleeve pipe are arranged on the same straight line.
Described first post insulator and the tube type bus at the second post insulator top and vertical connection of tube type bus at second post insulator, lightning arrester, voltage transformer and GIS sleeve pipe top.
Adopt novel inlet wire to draw the mode of connecing; Equipment optimization cloth postpones such as the lightning arrester on the inlet wire, voltage transformer, GIS sleeve pipe are invaded the ripple overvoltage through thunder and lightning and are calculated, and the overvoltage level of each equipment is all in the protection range of lightning arrester.Through electric field and voltage simulation calculation, the electric field strength of conductive surface is significantly better than the built on stilts mode of connecing of drawing of two division flexible conductors, corona and noise also obviously be better than routine draw connect, arrangement.Owing to adopted the tubulose bus, the electric field strength of pipe matrix face is controlled finely, and maximum is about 1.15MV/m, and gold utensil surface field intensity also is controlled in the 1.5MV/m, the corona situation can not occur usually; Grading ring surface maximum field strength is 1.73MV/m, is slightly larger than pipe matrix face electric field strength, also within permissible value (the control reference value that ultra high voltage is outdoor is outdoor 2.0MV/m, indoor 1.5MV/m).The 1.5 meters electric field strength in ground can be controlled in the 18kV/m scope near the transformer, satisfy national standard.
Post insulator, lightning arrester, GIS sleeve pipe etc. are arranged in the GIS bus bar side, effectively utilized the vacant lot in power distribution equipment district, conventional layout is saved 25.4 meters of longitudinal sizes, for ultra-high voltage transformer station, because lateral dimension is bigger, be very significant so save the effect of taking up an area of.Simultaneously, the main transformer side does not have equipment such as lightning arrester, voltage transformer, is convenient to the installation of extra-high voltage transformer.This arrangement also can be saved 1000kV framework 1 and stride, and saves the nearly 130t of steel.The distance of GIS sleeve pipe to road that furthered simultaneously is very easy to the lifting of sleeve pipe.
