Abstract
The utility model relates to a high power induction coil with a huge current-carrying capacity, which is applicable to industrial frequency conversion induction heating with huge power and a big volume and comprises an induction coil. The induction coil is formed by a duplex winding of two or more groups of guide wires, and an input end and an output end of the induction coil respectively work in a parallel connection mode or respectively work in independent mode. The high power induction coil with the huge current-carrying capacity has the advantages of 1 being novel, unique and simple in structure, practical to use, high in the current-carrying capacity, small in heating productivity and high in efficiency, 2 having good mechanical strength compared with a high power volume hearth, and 3 being flexible in controlling current and good in applicability.
Description
Technical field
The utility model relates to a kind of high-power induction coil that can be used in a kind of super large ampacity of super high power, the heating of big capacity industry variable frequency induction, belongs to inductor and makes the field.
Background technology
Existing industrial variable frequency induction heater (coil), it on structural design the single-screw load coil, i.e. coil and lower coil parallel connection on the single spiral coil of two reverse lines, improve one times of copper pipe current-carrying thus, and what improve that ampacity uses is the sectional area that adds large copper pipe, but still difficulty or ease satisfy the needs of the big ampacity of super high power.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of high-power induction coil that can be used in a kind of super large ampacity of super high power, the heating of big capacity industry variable frequency induction.
Design: in industrial electromagnetic induction heating process, electromagnetic induction heater often is called electric furnace, induction furnace, and its operation principle is connected with induction furnace by a power frequency supply or variable frequency power supply substantially.The core of induction furnace is the induction coil of electromagnetic conversion, and power supply is supplied with alternate electric energy of induction furnace coil, and induction coil is converted into alternating magnetic field to alternating current, is used for the heating of metal furnace charge.Induction coil is limited in the position in space, and selecting for use between copper pipe size (suitable water cooling) and the coil turn is the relation of mutual restriction, and the copper pipe cross section is big, and under same height situation, the number of turn will be lacked relatively, otherwise, as the same.Past is not under the situation of super large at power, the tradition water-cooled copper can satisfy the requirement of induction coil operate as normal substantially, but be added in when power reaches the MW level on the induction coil, the ampacity of unit is too big on the conventional coil, easily heating, efficient is low, and the induction coil of the application design by two groups or two groups with upper conductor and around constituting, solved this technical barrier dexterously, and the input of induction coil, output both can respectively and connect work, also can work alone respectively, its connection and Current Control are very flexible.
Technical scheme: a kind of high-power induction coil of super large ampacity, it comprises induction coil, with upper conductor and around constituting, and the input of induction coil, output are respectively and connect work or work alone respectively by two groups or two groups for described induction coil.
The utility model is compared with background technology, the one, structural design novelty, uniqueness, simple, practical, ampacity is big, caloric value is little, efficient is high; The 2nd, for the burner hearth of high power capacity, mechanical strength is good; The 3rd, Current Control is very flexible, and applicability is strong.
Description of drawings
Fig. 1 is a kind of high-power induction coil configuration schematic diagram of super large ampacity.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of high-power induction coil of super large ampacity, it comprises induction coil 1, with upper conductor and around constituting, and the input of induction coil, output 2 and 3 are respectively and connect work or work alone respectively by two groups or two groups for described induction coil 1.Lead in the described induction coil 1 is a copper pipe.
Embodiment 2: on the basis of embodiment 1, the lead in the described induction coil 1 is the copper coin bar.Described copper coin bar is hollow copper coin bar or real core copper coin bar.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection range of the present utility model.
