Abstract
A kind of leakage field collocation structure, including the upper clamping piece and lower clamping piece for electrically disconnecting with other post arm-tie, being electrically connected with stem arm-tie respectively, and be electrically connected between the two by bypass cable.The utility model proposes a kind of leakage field collocation structure, by connecting the bypass cable of folder from top to bottom, it is possible to prevente effectively from flowing through the induced voltage in electric current and the electric loop as caused by leakage field in other post arm-tie and iron core.
Description
Technical field
The utility model is related to converter power transformer technical field, more particularly to a kind of leakage field collocation structure.
Background technology
Due to electric current very little caused by leakage field in conventional transformer, the short circuit of folder from top to bottom, return yoke and the formation of stem arm-tie
Ring will not produce hot-spot because of leakage field.But converter power transformer has large-scale on-load voltage regulation ability, its pressure regulation number of leads
Far more than conventional power transformer, what the magnetic field that pressure regulation lead is produced will be big is more.According to electromagnetic induction principle, the change of current becomes pressure regulation and drawn
The alternating magnetic field that electric current in line is produced through structural member and silicon steel sheets such as stem arm-ties, easily on some hardwares because
The leakage field that fundamental current harmonic electric current is produced jointly is excessively concentrated and makes local eddy currents loss density very big, produces local mistake
Heat, so as to influence the safe operation of product.
The content of the invention
In view of the above-mentioned problems, the utility model offer is a kind of to ensure the leakage field collocation structure of converter power transformer safe operation.
To solve the above problems, the technical scheme that the utility model is taken is：A kind of leakage field collocation structure, including respectively with
Upper clamping piece and lower clamping piece that other post arm-tie electrically disconnects, is electrically connected with stem arm-tie, and pass through bypass cable electricity between the two
Gas is connected.Avoid the less other post arm-tie of sectional area by electric current, cause other post edge and folder fringe region to overheat.It is logical
Bypass cable connection folder from top to bottom is crossed, makes bypass cable, folder from top to bottom, stem arm-tie along each core window formation short-circuited conducting sleeve, suppression
Leakage field processed.
Described other post arm-tie upper end is provided with arm-tie screw rod, be connected by arm-tie screw rod with other post upper beam and arm-tie screw rod and
Insulation sleeve is provided between other post upper beam；Insulation board is provided between described other post upper beam and upper clamping piece web；Described other post is drawn
Plate lower end is connected with lower clamping piece web, other post arm-tie is electrically disconnected with folder from top to bottom.
Connected between described bypass cable and upper clamping piece web and lower clamping piece web by terminal plate, bypass cable is to cut
Area 300mm2Copper stranded conductor, unilateral outsourcing 3mm insulation, is three per side cable.
Pressure regulation lead is electric current Rendezvous Point caused by leakage field, easy mistake by the stem arm-tie and stem upper beam junction of side
Heat, here provided with thick 10mm copper coins, improves radiating effect.
The utility model proposes a kind of leakage field collocation structure, by connecting the bypass cable of folder from top to bottom, can effectively it keep away
Exempt to flow through the induced voltage in electric current and the electric loop as caused by leakage field in other post arm-tie and iron core.
