Abstract
The utility model discloses a based on totally enclosed oil tank of 35kV power transformer, the totally enclosed oil tank of this power transformer include the oil tank body, set up sealed oil circuit groove on transformer tank body four corners, are equipped with the ripple steel sheet on the oil circuit groove, the oil circuit groove use transformer tank body axle center as the center according to clockwise setting on the four corners, be equipped with on oil tank these four internal angles and lead oily device. Owing to adopt above -mentioned structure, ripple steel sheet length has lengthened, improved heat radiating area, effectively utilized traditional ripple oil tank four corners cubical space, compare with traditional radiator and reduced the running cost, improved operating efficiency.
Description
Technical field
The utility model relates to a kind of oil tank of transformer, particularly relates to a kind of based on the hermetically sealed fuel tank of 35kV power transformer.
Background technology
Fuel tank is as the shell of oil-filled transformer, all formed by Plate Welding, its structure except have certain mechanical strength and meet transformer transport, run, maintenance time ask for something except, more important point is exactly to meet the non-leakage property of transformer oil in fuel tank.
The all-sealed structure of corrugated tank is mostly adopted as current full-sealed transformer, corrugated plating and fuel tank integral solder become an entirety, corrugated siding has heat radiation and breathing two kinds of functions, corrugated siding is along with the change of temperature, the size of load, the height of temperature of oil in transformer in fuel tank and automatically breathing, ensure transformer oil and air completely isolated, need not safeguard within the transformer life phase.
Because as oil tank of transformer, to the spatial limitation of corrugated plating and transformer oil, the mobility in fuel tank is to the requirement of wave height, and transformer loss is on the impact etc. in fuel tank integral heat sink face, limits the lifting of wave height and width.Increase along with transformer voltage raising and capacity increase the loss brought, corrugated tank cannot support the cooling requirements of transformer and the arrangement space of corrugated plating, and then corrugated tank is only limitted in the application of 10kV low capacity transformer.
Outside is mostly adopted to be connect by butterfly valve and plug-in radiator as 35kV power transformer tank, relate to the radiator installation depth of parallelism, plane of symmetry requirement is high, manufacture difficulty is large, joint face is many, hidden leakage defect point is many, and dismantles radiator when mostly being transport, also should increase oil conservator device in addition, require higher to in-site installation, operation maintenance etc., increase the cost to transformer maintenance requirement.In sum, no matter be to manufacturer or to user, all can produce or exist some direct or potential loss and risks.
Through adopting the retrieval of keyword arithmetic expression, retrieve relevant comparative's file 3 sections, closely related file 0 section, also do not find the oil circuit groove by being provided with the sealing of corrugated steel on oil tank of transformer body corner, to improve the thermal diffusivity of transformer, thus be suitable for the pertinent literature applied on high-power transformer.
Summary of the invention
The purpose of this utility model is to provide that a kind of radiator structure is effective, space utilization rationally, making and installation and be often as good as, run the non-maintaining hermetically sealed fuel tank of 35kV power transformer.
For achieving the above object, the technical solution adopted in the utility model is: the hermetically sealed fuel tank of this power transformer comprises oil tank body, and oil tank of transformer body corner arranges the oil circuit groove of sealing, and described oil circuit groove is provided with corrugated steel.
Preferably, for improving radiating effect and attractive in appearance, oil circuit groove centered by oil tank of transformer body axle center on corner by arranging clockwise.
Preferably, for ensureing effectively to protect fragile corrugated steel in transit, the oil circuit groove of oil tank body corner all stretches out corrugated steel.
Preferably, for ensureing oil tank body intensity, being convenient to again transformer oil flowing unobstructed, in oil tank body, four angles being provided with oil-guide device.
The beneficial effects of the utility model: owing to adopting said structure, compare with the transformer of prior art, extend corrugated steel length, improve area of dissipation, corrugated tank is made to be able to become feasible in the application of 35kV power transformer, effectively make use of traditional corrugated tank corner solid space, and oil circuit groove can suitably change length size according to transformer temperature rise calculated data, namely change corrugated steel length.Owing to considering the weather side of corrugated steel, its four sides corrugated plating radiating effect is comparatively even, advantageously in the temperature difference flowing of transformer oil in fuel tank with exchange heat, whole oil circuit groove is due to by the clockwise design in traditional Chinese culture, as fan blade, perfectly in harmony with heat radiation original idea.Meanwhile, because the oil circuit groove at fuel tank four sides all stretches out corrugated steel, outer limit can be done in transit, effectively protect fragile corrugated steel.
Prove through trial run, both ensure that transformer ran temperature rise, and met again the non-maintaining requirement of transformer, reduce operating cost compared with traditional radiator, improve operational efficiency, and decrease the accidental injury in equipment conveying process.
