Description
Technical field
The present invention relates to a kind of oily formula transformer, particularly relate to a kind of high security oil formula transformer with fusible core protective device.
Background technology
Prior art oil formula transformer is generally direct to be electrically connected external high pressure line by HV Terminal and high-tension coil; the external automatic safety device of main dependence transformer is taken precautions against and is reduced because power load constantly changes; and the impact of thunder and lightning; there is certain safe effect; but; the actual service condition of existing oily formula transformer shows; the external environment condition that transformer uses is changeable, complicated; often because the inefficacy of protective device, thunder and lightning are crossed protective device and directly impacted transformer; and the fluctuation of power load is excessive etc., causes transformer to burn.The security performance of prior art oil formula transformer has to be hoisted.
Summary of the invention
The object of the invention is to make up the deficiencies in the prior art, design the high security oil formula transformer of band fusible core protective device, promote the security performance of oily formula transformer, and then promote the useful life of oily formula transformer.
Technical scheme of the present invention is as follows:
High security oil formula transformer with fusible core protective device; comprise fuel tank and be positioned at the iron core of its inside; and be wrapped in the high-tension coil of iron core outside; the HV Terminal and low-voltage terminal that connect outside high and low pressure circuit is respectively had in fuel tank outer setting; HV Terminal comprises corresponding A phase, B phase, C phase three HV Terminal; it is characterized in that: one end that described HV Terminal is positioned at fuel tank internal is electrically connected with corresponding inlet wire, and inlet wire is electrically connected with corresponding high-tension coil by fusible core.
Described fusible core comprises A phase fusible core, B phase fusible core and C phase fusible core.
One end that described A phase HV Terminal is positioned at fuel tank internal is electrically connected with corresponding inlet wire, and inlet wire is electrically connected with corresponding high-tension coil by A phase fusible core; One end that B phase HV Terminal is positioned at fuel tank internal is electrically connected with corresponding inlet wire, and inlet wire is electrically connected with corresponding high-tension coil by B phase fusible core; One end that C phase HV Terminal is positioned at fuel tank internal is electrically connected with corresponding inlet wire, and inlet wire is electrically connected with corresponding high-tension coil by C phase fusible core.
Described fusible core is positioned at fuel tank internal, is indirectly fixed on iron core top.
Step-up side electric current flows through successively " three-phase inlet wire---fusible core---transformer high-voltage coil ", plays available protecting transformer coil and is not burnt.
The invention has the beneficial effects as follows: the design's product, by installing fusible core additional in existing common transformer device body inside, first blows fusible core when big current comes, and protects transformer not burnt with this, thus play raising transformer safety performance, and useful life.

Embodiment
For being illustrated more clearly in content of the present invention, be further described below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2; high security oil formula transformer with fusible core protective device; comprise fuel tank 7 and be positioned at the iron core 6 of its inside; and be wrapped in the high-tension coil 4 of iron core 6 outside; the HV Terminal 1 and low-voltage terminal 8 that connect outside high and low pressure circuit is respectively had in fuel tank 7 outer setting; HV Terminal 1 comprises corresponding A phase, B phase, C phase three HV Terminal 1; one end that HV Terminal 1 is positioned at fuel tank 7 inside is electrically connected with corresponding inlet wire 2, and inlet wire 2 is electrically connected with corresponding high-tension coil 4 by fusible core 3.
Fusible core 3 comprises A phase fusible core 31, B phase fusible core 32 and C phase fusible core 33.
One end that A phase HV Terminal 1 is positioned at fuel tank 7 inside is electrically connected with corresponding inlet wire 2, and inlet wire 2 is electrically connected with corresponding high-tension coil 4 by A phase fusible core 31; One end that B phase HV Terminal 1 is positioned at fuel tank 7 inside is electrically connected with corresponding inlet wire 2, and inlet wire 2 is electrically connected with corresponding high-tension coil 4 by B phase fusible core 32; One end that C phase HV Terminal 1 is positioned at fuel tank 7 inside is electrically connected with corresponding inlet wire 2, and inlet wire 2 is electrically connected with corresponding high-tension coil 4 by C phase fusible core 33.
It is inner that fusible core 3 is positioned at fuel tank 7, is indirectly fixed on iron core 6 top.
During actual use, if big current causes fusible core to burn out, only need change the transformer fusible core burnt, and the low-voltage coil of high-tension coil and even correspondence can not be caused to burn out, thus improve the fail safe of transformer, extend transformer life.
Above-described embodiment can not think limiting the scope of the invention; the change that those skilled in the art make based on technical scheme of the present invention or means or improvement; protector, fuse etc. as adopted other to have excess current protective function substitute molten, within the protection range that all should fall into the claims in the present invention.
