A metal foil has the function of isolation as a metal isolation layer so as to decrease the interfering signal and purify the electrical network; the amorphous alloy as the iron core reduces the no-load loss and current and saves the energy; the hard combined insulating part makes the short circuit force not act on the iron core; and the clamp member and the backing plate lead the iron core to receive a small mechanical force so as to increase the short circuit resistance.
Description
Technical field
The utility model relates to the technical field of transformer, especially a kind of three-phase non-crystaline amorphous metal isolating transformer.
Background technology
Amorphous alloy transformer is excellent low-loss energy-economic transformer, it utilizes amorphous alloy material to replace silicon steel sheet to make iron core, make that transformer noload losses is low, no-load current is little, but non-crystaline amorphous metal is very responsive to mechanical force, during structural design, should avoid with iron core as main load-bearing structural member as far as possible.
There is not direct electrical link between winding of isolating transformer and the secondary winding, power consumption equipment and line insulation can be isolated, and winding and secondary winding can not interact, and just can reach the purpose that we want clean power supply, therefore are subjected to use more and more widely.
Anti-lightning strike, jamming-proof characteristic that isolating transformer has, can remove triple-frequency harmonics and reduce interference signal, the current distortion that prevents nonlinear load has influence on the operate as normal of AC power and electrical network is produced pollution, play the effect that purifies electrical network, thus the occasion that can be used for fail safe and have relatively high expectations.Traditional three-phase isolation transformer all is that material is made with the silicon steel sheet on core construction, and the loss of middle high frequency in silicon steel sheet type transformer is quite big, and energy-saving effect is not ideal enough.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the shortcoming and defect of above-mentioned existence, provide a kind of three-phase non-crystaline amorphous metal isolating transformer that can reduce no-load loss, reduce no-load current and raising transformer performance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of three-phase non-crystaline amorphous metal isolating transformer, comprise iron core, interior winding and outer winding, four frame five limbs type cores for reeling and form unshakable in one's determination by non-crystaline amorphous metal, interior winding and outside be provided with metallic spacer between the winding, the iron yoke outside unshakable in one's determination is provided with hard combined insulation spare, the two ends up and down of hard combined insulation spare are connected with upper padding plate and lower bolster respectively, at winding and upper padding plate, all be provided with cushion block between the lower bolster, the other end of upper padding plate is provided with upper clamping piece, the other end of lower bolster is provided with lower clamping piece, upper padding plate, lower bolster and hard combined insulation spare are bolted to connection, and are fixed with the pad pin in the lower surface of lower clamping piece.
In order to shield the harassing and wrecking harmonic components in the electrical network, the material of metallic spacer is a metal forming.
In order to increase the stability of isolating transformer, upper padding plate, lower bolster and upper clamping piece, lower clamping piece are bolted to connection.
The beneficial effects of the utility model are, compare with traditional dry-type transformer, and the utility model has adopted metal forming to play buffer action as metallic spacer, thereby has reduced interference signal, purify electrical network; Use the non-crystaline amorphous metal of high magnetic property to make iron core, effectively reduce no-load loss, no-load current and saved the energy; On structure, hard combined insulation spare, the short-circuit force when making short circuit in winding does not affact amorphous alloy in the heart, and folder and backing plate etc. also makes iron core be subjected to smaller mechanical force, has therefore improved the anti-short circuit capability of transformer.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
