Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of 110kV power transformer outlet structure, the setting height(from bottom) of transformer transporting height and transformer body oil conservator can be reduced, and high-voltage leading-out wire can be avoided to deform and displacement, also can reduce field erected workload simultaneously.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions: a kind of 110kV power transformer outlet structure, comprise 110 kV transformer bodies, high-voltage leading-out wire, current transformer, outlet raises seat and 110 kV pluggable cable terminals, described outlet raises the side that seat is installed on described 110kV transformer body, described high-voltage leading-out wire comprises vertical lead-out wire and horizontal lead-out wire, described vertical lead-out wire is arranged in described 110kV transformer body, described horizontal lead-out wire is arranged at described outlet and raises in seat, the end of described vertical lead-out wire has a kink, the kink of described vertical lead-out wire end is connected by connecting bolt with the head end of described horizontal lead-out wire, described current transformer is installed vertically on described outlet and raises in seat, described 110kV pluggable cable terminal is connected with the ending vertical of described horizontal lead-out wire by an inverted T-shaped joint, the two ends place of described horizontal lead-out wire is respectively provided with an insulating blanked clamper gripping member.
Further, described outlet rising seat is connected by the side of flange with described 110 kV transformer bodies.
Compared with prior art, the invention has the beneficial effects as follows: (1) high-voltage leading-out wire comprises vertical lead-out wire and horizontal lead-out wire, thus 110kV high-voltage leading-out wire is finally drawn in a horizontal manner, and outlet raises the side that seat is arranged on transformer body, reduces the shipping height of transformer and the setting height(from bottom) of transformer body oil conservator; (2) be connected by connecting bolt between horizontal lead-out wire with vertical lead-out wire, namely horizontal lead-out wire is demountable structure, realizes the disassembled for transport that outlet raises seat; (3) current transformer is installed vertically on outlet and raises in seat, achieves current transformer and raises seat and outlet raises uniting two into one of seat; (4) the two ends place of horizontal lead-out wire is respectively provided with an insulating blanked clamper gripping member, to be fixed horizontal lead-out wire, to effectively prevent the distortion of the horizontal lead-out wire caused by electric power, offset phenomena, improves transformer reliability of operation; (5) 110kV pluggable cable terminal is connected in vertical with the end of horizontal lead-out wire by an inverted T-shaped joint, thus the deadweight of 110kV inlet wire cable is born by the fastening bolt carrying out vertically arranged inverted T-shaped joint and coordinate with inverted T-shaped joint completely, Moment can not be produced to pluggable cable terminal, without the need to applying extra support to cable, reduce field erected workload.
