With the development of China's power transmission and transformation industry and transformer industry, the capacity of transformer is increasing, voltage class Also it is higher and higher, so large-scale and oversized transformer application is also more and more extensive.In high-power transformer, filled to realize The cooling effect divided, frequently with forced oil-circulation Directed cooling mode.During transformer station high-voltage side bus, after cooler or radiator cooling Transformer oil from leading on cooler or the oil guide pipe of bottom radiator, oil guiding box, lower clamping piece through transformer oil lower box part Oil box, device body lower guide lubricating pad block enter inside device body, under the action of oil pump and itself guide frame, make oil along regulation Path cycle rise, and constantly carry out inside device body heat transfer, heat radiation, heat exchange to take away coil inside and surface Heat achievees the effect that device body cools down.Deep fat dissipates after fuel tank upper space converges, then by the oil guide pipe inflow of top of oil-tank In hot device (OFAF) or cooler (ODAF).

As shown in Fig. 1~2, forced oil-circulation guide frame of the prior art is in the Oil Guide of inside transformer generally use Arrangement be oil tank bottom alongst both sides welding long axis oil guiding box, between described two long axis oil guiding box along The width of oil tank bottom welds multiple short axle oil guiding box, and each short axle oil guiding box both ends are hung down respectively with the long axis oil guiding box of both sides It is direct-connected logical, and the lower clamping piece oil guiding box connection also corresponding with top of each short axle oil guiding box, it is logical to be consequently formed transformer oil flowing Road.The drawbacks of this structure, is, when transformer capacity grade is larger, the size of transformer is also larger, in order to clear up weldering completely Remaining welding slag when connecing on long axis oil guiding box, it is necessary to equidistantly open up multiple cinder cleaning holes, to realize manual scarfing cinder operation, although Such mode can also realize the purpose of cleaning residual welding slag, but due to being manual operations, and there are the factors shadows such as visual dead angle It rings, welding slag is difficult to clean up totally, influencing the safe operation of transformer.In addition this structure opens multiple cinder cleaning holes, also increases manufacture Cost, and manual operations is difficult, scarfing cinder is time-consuming and laborious.Furthermore this structure fuel tank is not easy leak test, can cause poor sealing, exist Oil leak risk.Therefore consider that this structure is not optimal selection, it is necessary to make from transformer economic angle and safe operation angle It improves.

Utility model content

The purpose of this utility model is to provide a kind of power transformer forced oil-circulation guide frames, utilize molding glass Glass fibre pipe replaces the structure of existing oil tank bottom welding oil guiding box, and generated welding slag when avoiding welding oil guiding box saves life The scarfing cinder processing links in manufacturing process are produced, has evaded the high qualifying point of risk, has improved transformer station high-voltage side bus security performance, In addition the installation of the utility model structure is simple, saves the operating time, greatly reduces the production cost of transformer, improve transformation The market competitiveness of device.

The purpose of this utility model is achieved through the following technical solutions：

A kind of power transformer forced oil-circulation guide frame, including horizontal glass fiber oil guide pipe, vertical glass fiber Oil guide pipe and device body Oil Guide cushion block, wherein being alongst separately installed with horizontal glass fiber in transformer oil bottom both sides Oil guide pipe, each horizontal glass fiber oil guide pipe upside is vertically fixed with multiple vertical glass fiber oil guide pipes, in each water Multiple device body Oil Guide cushion blocks, and the vertical glass on each horizontal glass fiber oil guide pipe are equipped with above flat glass fibre oil guide pipe Glass fiber oil guide pipe connects one to one with the device body Oil Guide cushion block above the horizontal glass fiber oil guide pipe.

Vertical glass fiber oil guide pipe quantity on described two horizontal glass fiber oil guide pipes is identical.

The horizontal glass fiber oil guide pipe oil-inlet end is connected with transformer oil inlet pipe.

The advantages of the utility model is with good effect：

1st, the utility model replaces the structure of existing oil tank bottom welding oil guiding box using molding fiberglass pipe, avoids Generated welding slag when welding oil guiding box saves the scarfing cinder processing links during manufacturing, has evaded the high quality of risk Control point improves transformer station high-voltage side bus security performance.

2nd, the installation of the utility model structure is simple, saves the operating time, greatly reduces the production cost of transformer, improves The market competitiveness of transformer.
