Abstract
Full-sealed transformer cable box portable observation window is the deficiency could must dismantled with specific purpose tool to solve old-fashioned observation window, and a kind of convenient type observation window of invention, namely ensure that the sealing property of observation window, also can without the free-hand dismounting of specific purpose tool.It comprises tightening cover, self-locking stopping lock, toughened glass, O-ring seal and spacing base plate.Described spacing base plate is directly welded on box or the shell by air-insulated electric equipment.Concrete structure: it adopts the ring packing cushion rubber of trough of belt to be tightened together by toughened glass, then embed after tightening cover compresses and become as a whole, and tightening cover is tightened on the spacing base plate that is welded on transformer cable case, the self-locking stopping lock that increase by two is corresponding on tightening cover, tightening cover is fixed on spacing base plate, prevents observation window from loosening when transporting or coming off.The utility model is rational in infrastructure, inspection when namely water proof and dust proof is also convenient to operation maintenance, and be convenient to maintenance when damaging rear replacing or inspection, its material is convenient to large quantities of buying, one time punching moldedly can be mass, and cost is lower.
Description
Technical field
The utility model relates to the observation window on a kind of transformer cable case, particularly relates on a kind of full-sealed transformer high-low pressure box and cable box and does not need specific purpose tool and dismountable observation window.Observation when being mainly used in transformer operation maintenance and quick-detachment.
Background technology
On the electric equipment of regular air insulation, generally for the ease of observing electric connecting point running status or instrumented data, all can observation window be set, and most observation window is in order to prevent from coming off or in order to fixing, what adopt is all that bolt-locking or employing fluid sealant cement, in the box particularly generally needing the high-low pressure sleeve pipe of transformer to be all enclosed in a water-proof sealing on full-sealed transformer or cable box, box needs installation Sealed Observation Window, namely inspection when water proof and dust proof is also convenient to operation maintenance, but the structure of the seal cover that old-fashioned observation window generally adopts the thick metallic plate of 4.0mm to make after machine work and multi-layer sealed cushion rubber, by specific purpose tool, hermetyic window is fastened in observation window flange bottom plate by multiple bolt, this kind of structure can only be dismantled with specific purpose tool, be not easy to maintenance when damaging rear replacing or inspection, and maintenance cost and cost higher, be unfavorable for cost-saving.
Summary of the invention
The utility model is to solve old-fashioned observation window complex structure, and material usage is large, and the deficiency could must dismantled with specific purpose tool, and a kind of convenient type observation window of invention, namely ensure that the waterproof sealing performance of observation window, save raw material, also can without the free-hand dismounting of specific purpose tool.
For achieving the above object, the utility model adopts following technical proposals: full-sealed transformer cable box portable observation window, it comprises tightening cover, self-locking stopping lock, toughened glass, O-ring seal and spacing base plate.Spacing base plate is directly welded on the shell by air-insulated electric equipment such as box or cable box.Its concrete structure: the utility model adopts the ring packing cushion rubber of trough of belt to be tightened together by toughened glass, then embed after tightening cover compresses and become as a whole, and tightening cover is tightened on the spacing base plate that is welded on transformer cable case, the self-locking stopping lock that increase by two is corresponding on tightening cover, tightening cover is firmly fixed on spacing base plate, prevents observation window from loosening when transporting or coming off.
Described observation window tightening cover should match with the position of the self-locking stopping lock on spacing base plate.
Feature of the present utility model and beneficial effect
Solve the deficiency that old-fashioned observation window could must be dismantled with specific purpose tool, the utility model also can without the free-hand dismounting of specific purpose tool, it is rational in infrastructure, namely inspection when water proof and dust proof is also convenient to operation maintenance, be convenient to damage maintenance when rear replacing or inspection, its material is convenient to large quantities of buying, one time punching moldedly can be mass, reduce material cost and be convenient to installing/dismounting, can promote in the application sending exchanging electricity transformer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged diagram of self-locking stopping lock part in Fig. 1.
Embodiment
Referring to Fig. 1 and Fig. 2, full-sealed transformer cable box portable observation window, it comprises tightening cover 1, self-locking stopping lock 5, toughened glass 2, O-ring seal 3 and spacing base plate 4.Described spacing base plate 4 is directly welded on the shell by air-insulated electric equipment such as box wall 6 or cable box.Concrete structure: the ring packing cushion rubber 3 of trough of belt tightens together with toughened glass 2 by it, then embedding tightening cover 1, to compress rear one-tenth as a whole, and tightening cover 1 is tightened on the spacing base plate 4 that is welded on transformer cable case, the self-locking stopping lock 5 that increase by two is corresponding on tightening cover 1, tightening cover 1 is firmly fixed on spacing base plate 4, prevents observation window from loosening when transporting or coming off.
Described observation window tightening cover 1 should match with the position of the self-locking stopping lock 5 on spacing base plate 4.
During making, use stamping machine by one time punching molded for 1.5mm sheet metal be tightening cover 1, center is stamped into circular hole, and circular edges stamps out self-locking stopping lock 5 groove, punching press limit polish chamfering; Spacing base plate 4 is by the one time punching molded cylinder ring for band flanging of stamping machine, and correspondence position cuts out locking notch, coordinates with the self-locking stopping lock 5 of tightening cover 1; The annulus that seal gasket 3 makes trough of belt coordinates rear embedding tightening cover 1 with toughened glass 2.
Claims (2)
