Abstract

The invention discloses a novel circular-ring-shaped high-power electric reactor. The electric reactor comprises a magnetic core and a coil. The magnetic core is a circular-ring-shaped magnetic core formed by two identical semicircular-ring-shaped magnetic core bodies in a combined mode, the diameter of the circular-ring-shaped magnetic core ranges from 7 inches-20 inches, and the magnet density of the circular-ring-shaped magnetic core ranges from 5.5 g / cm<3> to 6.2 g / cm<3>. The two semicircular-ring-shaped magnetic core bodies are sleeved with the coil which is a spiral varnished wire coil formed by a flat wire in a vertical winding mode. The semicircular-ring-shaped magnetic core bodies are formed by pouring a magnetic composite material composed of ferromagnetic powder and high-temperature resin adhesive through a semicircular-ring-shaped mould. The electric reactor is simple in structure, low in production cost, light in weight, low in noise, low in loss, good in surface heat dissipation and long in service life; the process is simple, and automatic operation is easy to achieve; the utilization rate of the magnetic core is high, magnetic leakage is small, and the EMI effect is good.

Description

technical field [0001] The invention relates to the technical field of inductance components, in particular to a new type high-power annular reactor and a manufacturing method thereof. Background technique [0002] As a means of reactive power compensation, reactors are indispensable in power systems. The reactor is used to limit the current impact caused by the sudden change of the grid voltage and the operating process voltage, smooth the peak pulse contained in the power supply voltage, or smooth the voltage defect generated when the bridge rectifier circuit commutates, effectively protect the frequency converter and improve the power factor, it It can not only prevent the interference from the power grid, but also reduce the pollution to the power grid caused by the harmonic current generated by the rectifier unit. [0003] The manufacturing process of traditional silicon steel reactor is complicated and the production cost is high. Its manufacturing process mainly inc...
