Embodiment 1

[0053] A transformer moisture-proof and magnetic isolation device, including a safety slot 6 arranged on the peripheral side of the transformer body 1, a protection mechanism arranged in the safety slot 6, a guard plate mechanism arranged on the safety slot 6, and a protection mechanism arranged on the safety slot 6. The safety mechanism in the safety groove 6, the drying mechanism 19 that is arranged in the described safety groove and cooperates with the described safety mechanism, and is arranged in the described safety groove and is used to cooperate with the described protection mechanism, guard plate mechanism, safety mechanism A control mechanism connected to the drying mechanism;

[0054] The safety groove 6 is a plurality of rectangular grooves arranged on the side of the transformer body 1 and connected end to end;

[0055] The drying mechanism includes a drying fan 194 arranged on the inner wall of the rectangular groove, a drying pipe 193 arranged at the rear of the...

Embodiment 2

[0070] It differs from Embodiment 1 in that: a top protection module is provided at the top of the winding bin 97, and the top protection module includes a first top telescopic rod 98 arranged on the winding bin 97, which is arranged on the first The top rotary platform 94 on the top telescopic link 98, the second top telescopic link 101 that is arranged on the top rotary platform 94, the shielding umbrella 103 that is arranged on the second top telescopic link 101, is arranged on the top rotary The third top telescopic pole 100 adjacent to the second top telescopic pole 101 on the platform 94 is used to control the opening and closing of the shielding umbrella 103 .

[0071] The first top telescopic rod 98 is arranged on the upper end of the winding bin 97 through an angle adjustment motor arranged on the upper end of the winding bin 97 .

[0072] The umbrella surface of the shielding umbrella 103 is a metal mesh surface, and a bridging mesh surface 102 is provided on the low...

Embodiment 3

[0075] Such as image 3 and 14 As shown: the difference between it and the second embodiment is that the guard plate body 3 used is composed of two long plates 33 and two short plates 34. This design method can reduce the complexity of the mechanism. A pressure plate structure is provided at the junction to ensure that the short boards can also be locked when the long boards are stored and combined.

Abstract

The invention provides a moisture-proof magnetic isolating device for a transformer. The magnetic isolating device comprises a safety groove formed in the circumference of a transformer body, a protection mechanism arranged in the safety groove, a guard plate mechanism arranged on the safety groove, a safety mechanism arranged in the safety groove, a drying mechanism arranged in the safety grooveand matched with the safety mechanism, and a control mechanism arranged in the safety groove for being connected with the protection mechanism, the guard plate mechanism, the safety mechanism and thedrying mechanism. According to the moisture-proof magnetic isolating device for the transformer, each mechanism is controlled and coordinated, and the incorporation of the protection mechanism into the safety groove is achieved when strong convective weather or maintenance of the transformer or power failure occurs, use safety of the device is ensured, online magnetic insulation on site can be achieved, the safety groove can be quickly dried, meanwhile a small space is occupied, self-protection can be achieved in disaster weather, and damage caused by the strong convective weather is prevented.
