Embodiment 1

[0028] The flexible additional transformer includes a flexible coil winding and an output terminal 4 of the coil winding which are additionally installed on the iron core of the transformer. The flexible coil winding 6 is fixed on the base 1 , and the base 1 is fixed on the support 3 of the transverse iron core 7 via the clamp plate 2 . The flexible coil winding 6 is assembled around the transverse iron core 7 of the transformer, and the flexible coil winding 6 is provided with an output terminal 4 . The flexible coil winding 6 is a flat single-row in-line butt joint coil winding structure, and the flexible coil winding 6 is formed by plugging the winding wires through the plug-in terminals 5 . The lead wire of the flexible coil winding 6 is multi-filament copper wire, the turn insulation is polytetrafluoroethylene heat-resistant insulating material, and the flexible coil winding has a silicone sheath 8 outside.

Embodiment 2

[0030] The flexible coil winding of the flexible additional transformer is an in-line open-loop coil winding structure. Coil winding 9 is 4 groups, is connected as three-phase power output by the mode shown in Figure 5. Other structures are with embodiment 1.

[0031] The flexible additional type transformer of the present invention is used as a protective power supply, adopts a flexible additional type coil winding, and has the following technical characteristics: (1) The winding wire is a multi-wire copper wire. Due to the good heat dissipation conditions of the winding structure, when designing the cross section of the wire, you can refer to the conventional The value increases the current density by 2 times to save copper. (2) Teflon heat-resistant insulating material for turn insulation, or directly use heat-resistant 150°C plastic wire. (3) The number of prefabricated winding turns can be combined arbitrarily according to the design requirements, plus a silicone sheath...

Abstract

The invention relates to a flexible additional-style transformer, belonging to the technical field of transformers. The flexible accessional-style transformer is characterized in that the transformer comprises a flexible coil winding and a coil winding output terminal which are additionally arranged on an iron core of the transformer. The flexible coil winding is winded onto the iron core of the transformer and the output terminal is arranged on the flexible coil winding. The invention has the advantages that the structure is simple; the manufacturing process is simplified; the work efficiency is high; the occupied area is less; the investment cost is low; accident hidden troubles can be eliminated; the reliability of the system operation can be enhanced, etc.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a flexible additional transformer. Background technique [0002] At present, the rated voltage level of submersible variable frequency electric pumps in wellhead tanks in oil fields is mostly in the range of 2KV to 6KV, and the voltage levels of dry-type transformers and box-type substations that supply power to them are also the same, while the automatic control system of submersible variable frequency electric pumps, The working power supply of dry-type transformer automatic cooling system, high-voltage switchgear operation and relay protection system is 220V / 380V. Due to the different voltage levels, the existing technical solution to the problem is to provide another 220V / 380V power supply; the second solution is to configure a small-capacity power transformer to provide 220V / 380V power supply; the third solution is to integrate multi-coil multi-voltage level dedicated ...
