Abstract
The utility model relates to an electric power reactor belonging to the electric technical field, which is characterized in that the coil of the hollow iron core reactor comprises multi-strand enameled wires, the components of which are shown on picture 1, wherein the 1 is enameled aluminum wire. The current in the electric power reactor has a higher harmonic component besides the power frequency component, thereby the current distribution in solid flat copper or aluminum wires is driven to the conductor surface as the rise of the frequency, and the skin depth is smaller if the frequency is higher, as a result of the skin effect. That is to say, the power frequency current and the harmonic current are only on the surface of the solid flat conductor, and are more on the surface if the frequency is higher, thereby the resistance of the solid flat copper or aluminum wires groves as the current harmonic frequency increases, so the consumption of the coil increases. The coil in the utility model is capable of effectively avoiding the skin effect when in practical use by utilizing the multi-strand enameled wires structure, and capable of reducing the temperature rise in the coil caused by the power frequency current and the harmonic current of the electric power reactor, thereby reducing the loss of the conductor and reducing the production cost.
Description
Technical field
The utility model technical field of electricity particularly relates to a kind of power reactor.
Background technology
In the prior art, power reactor mainly contains two kinds of air-core reactor, iron core reactors, the coil of these two kinds of reactors is real core flat copper, aluminum steel, because the electric current that flows through in the power reactor, particularly filter reactor also has harmonic current except that power current, the frequency of harmonic current is greater than work frequency, and harmonic current is because skin effect is, distribution in real core flat copper, aluminum steel is tending towards conductive surface with the rising of frequency and distributes and flow, and frequency is high more, and skin depth is more little.Just harmonic current is in real core strip conductor, frequency is high more, be tending towards Surface runoff more, the resistance that is real core flat copper, aluminum steel increases with the increase of harmonic frequency, the loss of coil, the heat of generation are increased, therefore, when having harmonic current to flow through, the temperature rise of its coil is higher with the reactor of real core flat copper, aluminum steel coiling.In order to reduce the temperature rise of coil, the high more current density of choosing real core flat copper, aluminum steel of frequency is low more when designing usually, like this, has increased copper, aluminum steel consumption, has strengthened the weight of filter reactor and has improved product cost.
Summary of the invention
The purpose of this utility model is to provide a kind of power reactor, and it can overcome the existing deficiency of reactor that adopts real core flat copper, aluminum steel coiling.
The purpose of this utility model is to adopt such technical scheme to realize: it is characterized in that described coil is formed by the set of multiply enamel insulated aluminium wire.
Because coil of the present utility model adopts the structure of multiply enamel insulated aluminium wire, can effectively reduce power frequency and the temperature rise of harmonic current in coil in actual use, and can reduce product cost.
Below in conjunction with drawings and Examples, the utility model is further specified.

Fig. 2 is the cross section structure schematic diagram of the utility model coil
Embodiment
With reference to Fig. 1, Fig. 2: the utility model comprises coil holder 2 and coil 1, coil 1 is formed by 5 set of aluminium matter enamelled wire, described coil holder is formed by connecting in known manner by pedestal 4, insulating part 3 and bobbin 2, coil 1 is arranged in the bobbin 2, the diameter of described aluminium matter enamelled wire 5 flows through reactor in the time of can using according to reality power frequency size is selected, and the diameter range of aluminium matter enamelled wire 5 is: 0.2mm-2.5mm.
The coil 1 that the utility model adopts 5 set of aluminium matter enamelled wire to constitute is the reactor of winding, and it can effectively reduce coil temperature rise, reduces coil 1 lead consumption and reduces product cost.Its employed coil 1 adopts aluminium matter enamelled wire 5 to replace the coil of real core flat copper, aluminum steel coiling in original power reactor, coil is the structure of enamel insulated aluminium wire set, the coil that not only can be used for the hollow power reactor equally also can be used as the coil of iron core power reactor.
