Abstract
A double low-voltage power supplying transformer with epoxy resin pouring relates to a dry type transformer. Currently, a transformer can only supply power to one load, and two transformers are required to supply power to two different loads, thereby having high cost, large occupied area and inconvenient transportation. The double low-voltage power supplying transformer comprises a triple-iron core post, a low-voltage winding and a high-voltage winding. The low-voltage winding and the high-voltage winding are both concentrically sleeved on the iron core post, made by winding conducting wires and poured by resin for insulation. The transformer is characterized in that the low-voltage winding includes a first low-voltage winding and a second low-voltage winding sleeved outside the first low-voltage winding, and independent lead wires are respectively arranged on the first low-voltage winding and the second low-voltage winding. The first low-voltage winding and the second low-voltage winding are sleeved outside the iron core post and capable of respectively supplying power to different three-phase loads to realize the function of supplying power to two different loads by one transformer, and compared with using two transformers, the transformer has the advantages of low production and maintenance costs, small volume and convenient transportation and installation.
Description
Technical field
The utility model relates to a kind of dry-type transformer, refers to the poured with epoxy resin transformer of a kind of pair of low-voltage power supply especially.
Background technology
At present, the double winding power transformer of a poured with epoxy resin can only be to an electric, if when two different electric, then need 2, and the cost height, floor space is big, and transportation is inconvenient.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition is that the prior art scheme is improved and improved, the poured with epoxy resin transformer of a kind of pair of low-voltage power supply is provided, make it can be two different threephase load power supplies, reduce cost, reduce the purpose of volume to reach.For this reason, the utility model is taked following technical scheme: the poured with epoxy resin transformer of two low-voltage power supplies, comprise that three iron core column, concentric locking collar are connected on two low pressure windings and the high pressure winding on the iron core column, described two low pressure windings and high pressure winding insulate by the lead coiling and with resin-cast, it is characterized in that: the described first low pressure winding and be coated at the second low pressure winding of the first low pressure winding, the described first low pressure winding and the second low pressure winding are equipped with independently lead-in wire.The first low pressure winding and the second low pressure winding are independent mutually on electric, the first low pressure winding that is coated at iron core column can be respectively to different threephase load power supplies with the second low pressure winding, realization is by the function of a transformer to two different loads power supplies, compare two transformers, the utlity model has production, maintenance cost is low, volume is little, transportation, advantage easy for installation.
As further improving and replenishing to technique scheme, the utility model also comprises following additional technical feature: be provided with stay and the cushion block that is used to keep both concentricitys between the described iron core column and the first low pressure winding, described cushion block is positioned at the upper/lower terminal of iron core column; Be equipped with the insulating cylinder that is used to reduce partial discharge between the described first low pressure winding and the second low pressure winding and between second winding and the high pressure winding.Insulating cylinder has reduced the inner partial discharge of transformer, improves transformer electric insulation intensity, has prolonged transformer useful life.
The lead-in wire of the described first low pressure winding and the second low pressure winding is connected with independent outlet with the copper bar of being located at the transformer upper/lower terminal respectively.
The bottom of transformer is provided with the low frequency damping spring cushion.The low frequency damping spring is used to reduce the low-frequency band Oscillation Amplitude.
Beneficial effect: the first low pressure winding and the second low pressure winding can be realized the function of two transformers respectively to different threephase load power supplies, compare two transformers, the utlity model has productions, maintenance cost is low, and volume is little, transport, advantage easy for installation.Set up the low frequency damping spring cushion, reduce the low-frequency band Oscillation Amplitude, abate the noise.
