Abstract
The utility model relates to a double-seal diaphragm type oil conservator, belonging to the container class. The utility model is composed of an oil conservator casing, and a diaphragm which is connected with the inner box edge which is arranged along the inner periphery of the outer casing of the oil conservator. The inner box edge is arranged under the outer box edge. The utility model has the advantages of good sealing performance, no oil seepage, safe operation of the transformer, and easy application. The replacement cycle of the oil is extended form 3.5 to 6 times, the workload of the maintenance person is lowered, and the utility model is suitable for being installed on various large-sized transformers.
Description
This practicality newly relates to a kind of double containment barrier film oil conservator, belongs to container class, is specially adapted to dress usefulness on the large oil immersed formula transformer.
China present large oil immersed formula transformer oil conservator is to such an extent as to experienced three kinds of versions of general expression, the present widely used diaphragm type storage oil cabinet of capsule-type from structure.Situation from the reflection of operation power department, though the latter has very big carrying out for more preceding two kinds, but nearly all oil conservator all has oil seepage phenomena in various degree to exist, thereby the intrusion that causes air makes transformer oil ageing, oxygenated oil potential drop low, shorten the replacement cycle, the situation that is lower than normal operation oil level happens occasionally, the safe operation of serious threat transformer.Having increased the work of maintenance personnel amount, so there are the problems referred to above, is due to unreasonable and manufacturing process is difficult to guarantee because of its structural design.The problems referred to above are perplexing the operation power industry, are never solved preferably.
The purpose of this utility model is to provide a kind of good seal performance, non-leakage oil, prolong oil replacement cycle, easy to manufacture, reduce attendant's workload, guarantee the double containment diaphragm type storage oil cabinet of transformer safe operation.
The purpose of this utility model realizes by the following technical solutions, by top be provided with oil level gauge that inspection opening, dehydrating breather connect mouth, end, bottom dirt trap, add, the Oil Tank shell and the barrier film of drain line joint, butterfly valve form, its described special-shaped barrier film links to each other with the interior case edge that is provided with along Oil Tank shell inner peripheral, its special-shaped barrier film is provided with the bearing that deflating valve links to each other with the oil level gauge connecting rod, outer container on the Oil Tank shell along 1 in interior case along 2 on, and under its outer container edge, two ends, be provided with drain plug.
The outlet of described butterfly valve links to each other with the oil inlet pipe of transformer.
Described Oil Tank housing designs is geometry such as circle, hexagon, octangle.
The utility model compared with prior art, owing to adopted the interior case edge that special-shaped barrier film is linked to each other, be positioned at the technical measures under the outer container edge, just formed the version of double containment, so have the replacement cycle of good seal performance, non-leakage oil, oil to prolong 2.5-5 times, greatly reduce the work of maintenance personnel amount, guarantee the advantages such as safe operation of transformer, simultaneously assembly technology simple, implement easily, be beneficial to and apply.
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is an A-A sectional structure schematic diagram.
Fig. 3 is the another hexagon Oil Tank of a utility model shell.
Fig. 4 is the another octangle Oil Tank of a utility model shell.
Embodiment of the present utility model is described in conjunction with the accompanying drawings, Oil Tank shell (12) is by the last lower house of steel through machine-shaping, it is fused along (1) by outer container, its top is provided with inspection opening (5), dehydrating breather connects mouth (7), the end is provided with oil level gauge (8), drain plug (9), bottom are provided with dirt trap (11), place oil pipe spigotjoint, butterfly valve (10), oil resistant abnormity diaphragm of rubber (3), link to each other along (2) with the interior case that is provided with along Oil Tank shell (12) inner peripheral, its special-shaped barrier film (3) is provided with deflating valve (4), with the bearing that links to each other with oil level gauge (8) connecting rod (6), the outer container on the Oil Tank shell (12) is positioned at case along on (2) along (1); The outlet of described butterfly valve (10) links to each other with the oil inlet pipe of transformer.Described Oil Tank shell (12) is designed to geometry such as circle, hexagon, octangle.
Claims (2)
1, a kind of double containment diaphragm type storage oil cabinet, it is characterized in that: inspection opening (5) is arranged by upper design, the dirt trap (11) that dehydrating breather connects oil level gauge (8) bottom of mouth (7) end places oil connection, the special-shaped barrier film of Oil Tank shell (12) (3) of butterfly valve (10) links to each other along (2) with the interior case that is provided with along Oil Tank shell (12) inner peripheral, described Oil Tank shell (12) is designed to circle, hexagon, octangle, its special-shaped barrier film (3) are provided with deflating valve (4) and the bearing that links to each other with oil level gauge (8) connecting rod (6).
2, according to the described a kind of double containment diaphragm type storage oil cabinet of claim 1, it is characterized in that the outer container on the Oil Tank shell (12) is positioned at case on (2) along (1), not on same horizontal plane, and have drain plug (9) on its outer container edges, two ends (1).
