Abstract
The present invention relates to the gas-collecting structure of transformer, especially a kind of transformer oil guide box gas-collecting structure.A kind of transformer oil guide box gas-collecting structure, comprise the transformer box cover of vault construction, the vault upper end of described transformer box cover is plane, vault upper end is domatic to the arch end, transformer tank covers the oil guiding box being welded with and being with the length of gradient very long, the highest point of described oil guiding box is provided with discharge joint, and oil guiding box inner bottom part transformer tank covers and offers some square gas ports, the different widths 1 ~ 5mm of transverse plane on the width of described gas port and transformer box cover vault.The gas-collecting structure of transformer of the present invention is simple, intensity reliable, successful, is a kind of structure that can meet the requirement of user's gas collection.
Description
Technical field
The present invention relates to the gas-collecting structure of transformer, especially a kind of transformer oil guide box gas-collecting structure.
Background technology
Traditional transformer box cover having gas collection to require adopts the structure of inclined-plane, both sides by-level, after inside transformer produces gas, gas is pooled to case lid by-level region along case lid inclined-plane, and by the discharge joint on case lid by gas collection in main gas tube, last gas arrives Buchholz relay.Discharge contact aperture is less, and plane place is horizontal zone, does not have gradient, is not easy to the circulation of gas, easily causes the alluvial of gas, finally affects the result of gas collection test.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of transformer oil guide box gas-collecting structure.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of transformer oil guide box gas-collecting structure, comprise the transformer box cover of vault construction, the vault upper end of described transformer box cover is plane, vault upper end is domatic to the arch end, transformer tank covers the oil guiding box being welded with and being with the length of gradient very long, the highest point of described oil guiding box is provided with discharge joint, oil guiding box inner bottom part transformer tank covers and offers some square gas ports, the different widths 1 ~ 5mm of transverse plane on the width of described gas port and transformer box cover vault.
Further, the longitudinal cross-section of described oil guiding box is the very long right-angled triangle of hypotenuse.Design band hypotenuse, and the oil guiding box that length will be very long, the fastness of guarantee oil guiding box when only having longitudinal cross-section to be right-angled triangle.
Further, described gas port is rectangle structure.In order to avoid causing the alluvial of gas, increase gas flow rate, the area of gas port is the bigger the better, and due to the limited width of transverse plane on transformer box cover vault, but length is enough long, so arranging gas port is rectangle structure.
The invention has the beneficial effects as follows: the gas-collecting structure of transformer of the present invention is simple, intensity reliable, successful, is a kind of structure that can meet the requirement of user's gas collection.
Accompanying drawing explanation
Below in conjunction with accompanying drawing embodiment, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the end view of Fig. 1.
In figure: 1. case lid, 2. oil guiding box, 3. discharge joint, 4. gas port.
Embodiment
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to the present invention instead of limitation of the invention further are described.
As shown in Fig. 1 ~ 2, a kind of transformer oil guide box gas-collecting structure, comprise the transformer box cover 1 of vault construction, the vault upper end of transformer box cover 1 is plane, vault upper end is domatic to the arch end, transformer box cover 1 is welded with the oil guiding box 2 that the length of band gradient is very long, the longitudinal cross-section of oil guiding box 2 is the very long right-angled triangle of hypotenuse, the highest point of oil guiding box 2 is provided with discharge joint 3, oil guiding box 2 inner bottom part transformer box cover 1 offers some rectangular gas ports 4, the different widths 1 ~ 5mm of transverse plane on the width of gas port 4 and transformer box cover 1 vault.
When there is gas in transformer gas, collecting gas and doing experiment, analyze, contribute to judging gas componant, thus roughly judge transformer health status and failure cause.After gas produces, gas is pooled to case lid 1 vault upper end along transformer box cover 1 is domatic, because the gas port at case lid 1 vault place is larger, vault horizontal zone reduces, gas is easy to just enter oil guiding box 2, gas enters discharge joint 3 along the inclined-plane of oil guiding box 2, finally arrives Buchholz relay.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
Claims (3)
