Abstract

The utility model discloses an iron core for a magnetically-controlled reactor. The iron core comprises an upper iron yoke, a lower iron yoke and iron core columns. The iron core columns are connected with the upper iron yoke and the lower iron yoke and comprise an upper iron core column molded integrally with the upper iron yoke and a lower iron core column which is molded integrally with the lower iron yoke, the upper iron yoke and the lower iron yoke are in combined connection and in fixed connection through the upper iron core column and the lower iron core column. According to the iron core for the magnetically-controlled reactor, the iron core is formed by combination of the upper iron yoke and the lower iron yoke, the cooling performance of the iron core for the magnetically-controlled reactor is greatly improved, and the iron core is simple in structure, low in cost and high in practicality.

Description

A kind of magnet controlled reactor iron core

Technical field

The utility model relates to a kind of technical field of electronic equipment, specifically a kind of magnet controlled reactor iron core.

Background technology

Along with cable line in the formation of the big electrical network of superhigh pressure and the urban distribution network increases severely, the reactive power in the electrical network changes and problem such as voltage fluctuation becomes increasingly conspicuous.Measures such as the dynamic inhibition of enforcement reactive power dynamic equilibrium and voltage fluctuation, the secondary arc current when strengthening power network harmonic wave management, suppress the rising of EHV transmission long transmission line terminal voltage and reducing the circuit single-phase earthing, elimination generator self-excitation, safety and economic operation, promotion electrical network to electrical network are energy-conservation, significant.The magnet controlled reactor iron core generally is made up of many groups silicon steel sheet that last yoke and following yoke are wholely set at present, and heat dispersion is relatively poor, influences useful life.

Summary of the invention

At the deficiency that prior art exists, technical problem to be solved in the utility model is, provide a kind of simple in structure, improve the core of reactor heat dispersion, improve the magnet controlled reactor iron core in useful life.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of magnet controlled reactor iron core, formed by upper yoke, lower yoke and the iron core column that connects described upper yoke and lower yoke, described upper and lower iron yoke is connected, iron core column is by forming with the integrated upper core post of upper yoke and with the integrated lower core post of lower yoke, and described upper and lower iron yoke is fixedly connected by upper core post and lower core post.

The advantage of the utility model magnet controlled reactor iron core is: iron core is combined by upper yoke and lower yoke, has improved the heat dispersion of magnet controlled reactor iron core greatly, and simple in structure, with low cost, practical.

Fig. 2 is perspective view of the present utility model.

Embodiment

Below in conjunction with drawings and the specific embodiments the utility model is described in further details;

As shown in Figure 1, 2, a kind of magnet controlled reactor iron core, iron core column 3 by upper yoke 1, lower yoke 2 and connection upper yoke 1 and lower yoke 2 is formed, wherein, upper yoke 1 is connected with lower yoke 2, iron core column 3 is by forming with the integrated upper core post 31 of upper yoke 1 and with lower yoke 2 integrated lower core posts 32, upper yoke 1, lower yoke 2 pass through upper core post 31 and lower core post 32 fixedly connected.

Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection range of the present utility model.

Claims
