Abstract
The utility model relates to a dry type transformer, in particular to the dry type transformer with a single isolation transformer. The dry type transformer comprises a main transformer. The upper portion of the main transformer is provided with the single phase isolation transformer which is fixed with the main transformer. The dry type transformer with the single phase isolation transformer is compact in structure, convenient to mount and high in adaptability.
Description
Technical field
The utility model is a kind of dry-type transformer, particularly a kind of dry-type transformer with single-phase isolating transformer.
Background technology
The annex of general dry-type transformer band of the prior art is blower fan, temperature control etc., its power supply is generally single-phase 220V power supply, its power supply can be taken from the low-voltage single-phase electric source that low pressure is the distribution transformer of 400V, but some transformer low voltage is three-phase 690V or other special voltages, its single-phase voltage considers do not have to supply the operation 220V operating voltages such as blower fan, temperature control after the pressure drop, and in the power distribution room without other 220V single phase poaer supplies, can't satisfy normal demand.
Chinese patent 02264795.3, a kind of dry-type transformer is disclosed, have iron core, high and low pressure winding and be arranged on upper and lower cushion block between high and low pressure winding and the iron core, has the gap between the high and low pressure winding, be provided with the thick composite membrane insulating cylinder of 0.5～2mm in this gap, the upper and lower end of composite membrane insulating cylinder is connected with upper and lower cushion block respectively.This structure can't satisfy the demands, and impact is operation normally.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, compact conformation, and satisfy the operation needs, volume is little, the dry-type transformer with single-phase isolating transformer of being convenient to install.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of dry-type transformer with single-phase isolating transformer comprises main transformer, and the top of described main transformer is provided with the single-phase isolating transformer that fixes with it.
The no-load voltage ratio that isolation becomes into the secondary single-phase voltage of main transformer than 220V voltage, once connecing with the low pressure of main transformer that isolation becomes is single-phase, secondary connects and the equipment such as blower fan, temperature control.
As preferably, described single-phase isolating transformer is solid mutually by bracing frame with main transformer, and the bottom of described main transformer is provided with base.
Therefore, a kind of dry-type transformer with single-phase isolating transformer that the utility model provides, compact conformation, easy for installation, improve adaptability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as shown in Figure 1, a kind of dry-type transformer with single-phase isolating transformer comprises main transformer 1, and the top of described main transformer 1 is provided with the single-phase isolating transformer 2 that fixes with it.Described single-phase isolating transformer 2 is solid mutually by bracing frame 3 with main transformer 1, and the bottom of described main transformer 1 is provided with base 4.
