Abstract
The invention discloses a multi-winding self-coupling transformer. A main body of the multi-winding self-coupling transformer is a support; a plurality of groups of transformer bodies; each group of transformer bodies comprises an iron core and a winding; the winding comprises a low voltage winding, a public winding and a series connection winding; the low voltage winding, the public winding and the series connection winding are connected serially; the low-voltage winding which is used as an input end is connected with input voltage; and the series connection winding which is used as an output end is connected with an output circuit. The multi-winding self-coupling transformer has the beneficial effects that the transformer has a simple structure, is reasonable in layout, firm in connection, long in service life, low in use cost and convenient to connect, and can be used for preventing the transformer from being damaged due to overheat of the coil; and the overall line arrangement is order.
Description
Technical field
The present invention relates to field transformer, specifically, specially refer to a kind of many winding autotransformers.
Background technology
Autotransformer belongs to motor and starts in short-term and use product, known autotransformer is mostly assembled by iron core, winding, channel-section steel, the autotransformer winding can generate heat in the starting process, the transformer Inside coil is worn out to be burnt out even, reduce the useful life of autotransformer, therefore there have been strict restriction starting time and the starting frequency.For improving this situation, there is the people that the structure of transformer has been done improvement,
Such as; number of patent application is 932004871.2 patent " Protector for transformer "; a kind of structure of protection equipment for transformer is disclosed; it is a kind of protective device that can finish automatic switchover when transformer departs from normal value; namely be connected in series normally opened contact and the thermal relay RJ of relay J 1 at three-phase power line; serial connection relay J 1 and thermal relay normally closed contact in control loop; connect a thermal protection circuit in supply line, the normally-closed contact of executive component J2 wherein is serially connected with in the control loop.Such structure has the function of excess temperature, overload and open-phase automatic protection, also can address the above problem, but as an annex of transformer, complicated structure, parts are more, and cooperation is therebetween had relatively high expectations, and installs also inconvenient.A plurality of taps in the past the autotransformer secondary coil are put irregularly besides, cause easily wiring inconvenient, take each other firm short circuit, and wiring is loosening easily, uses uneasy congruent problem.
Summary of the invention
The object of the present invention is to provide a kind of many winding autotransformers, by adopting the structural design of many windings, overcome the deficiency in the conventional art, thereby realized purpose of the present invention.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of many winding autotransformers, its main body is a support, described support is provided with some groups of transformer bodies, every group of described transformer body comprises iron core and winding, described winding comprises low pressure winding, common winding and series connection winding, described low pressure winding, common winding and series connection winding are by being connected in series, and the low pressure winding that is made as input is connected with input voltage, and the series connection winding that is made as output is connected with output circuit.
In one embodiment of the invention, described transformer body is provided with at least 5 groups, and the surface of the terminal block of transformer body is provided with epoxy resin layer.
In one embodiment of the invention, described support comprises the main frame that is comprised of first side, second side, the 3rd side and four side and is arranged at metal mounting strip on the main frame.
Beneficial effect of the present invention is: have simple in structure, rationally distributed; Overall routing is arranged in order, easy-to-connect, and wiring is firm, uses safety; Can prevent that transformer from burning out owing to coil is overheated, increase the service life, reduce the characteristics such as use cost.
Description of drawings
Fig. 1 is the structural representation of many winding autotransformers of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
Shown in Fig. 1, a kind of many winding autotransformers of the present invention, its main body is a support 100, described support is provided with some groups of transformer bodies 200, every group of described transformer body comprises iron core and winding, and described winding comprises low pressure winding, common winding and series connection winding, and described low pressure winding, common winding and series connection winding are by being connected in series, the low pressure winding that is made as input is connected with input voltage, and the series connection winding that is made as output is connected with output circuit.
In an embodiment of the present invention, in order to improve the insulation property of whole device, described transformer body is provided with at least 5 groups, and the surface of the terminal block of transformer body is provided with epoxy resin layer.
Especially it is pointed out that described support comprises the main frame that is comprised of first side, second side, the 3rd side and four side and is arranged at metal mounting strip on the main frame.
The present invention has simple in structure, and is rationally distributed; Overall routing is arranged in order, easy-to-connect, and wiring is firm, uses safety; Can prevent that transformer from burning out owing to coil is overheated, increase the service life, reduce the characteristics such as use cost.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
