Abstract
The utility model discloses an insulated radial iron core anode saturation resistor poured by epoxy resin, which is simple in structure, low in manufacturing cost and excellent in performance. The insulated radial iron core anode saturation resistor comprises a circular coil wound by a tubular conducting material with a hollow middle part. The insulated radial iron core anode saturation resistor is characterized in that two involutory U-shaped iron cores are installed on the two end faces of the coil, air gaps are formed on the two end faces of the U-shaped iron cores to form a group of iron cores, a plurality of groups of iron cores distributed in radiation are installed on the whole circular coil, the epoxy resin is filled and poured in the gap of the coil hugged by the U-shaped iron cores, and the iron cores are hugged with the coil through a special tightening band outside the iron cores. The insulated radial iron core anode saturation resistor has the characteristics of compact structure, small size, reasonable cooling and convenience in manufacture and installation; and especially, the epoxy resin is poured to fix each coil in the epoxy resin so as to effectively reduce noises, relieve flux leakage and improve the surge current bearing capacity.
Description
Technical field
The utility model is used for high-voltage direct-current transmission system, relates in particular to a kind of anode film reactor that is used for the high voltage direct current transmission apparatus.
Background technology
The anode film reactor is used for the converter valve of high voltage direct current converter, and it mainly acts on; The one, higher current-rising-rate (di/dt) that occurs when being used for thyristor element conductive in the limiting valve and higher surge current and cause the thyristor element and burnt; The 2nd, when thyristor is in the blocking interval circuit and higher voltage climbing (du/dt) occurs, to avoid the surge voltage that the thyristor element born and opening by mistake of causing is logical.Thereby the design of anode film reactor characteristic will be satisfied at thyristor and opens moment; The anode film reactor has very high impedance; And after in a single day setting up enough charge carriers in the thyristor element; The anode film reactor demonstrates very low impedance operator again, and this helps reducing the operating efficiency of converter valve.Common anode film reactor is equipped with one group of iron core on the full annular coil, whole reactor volume is big, Heavy Weight, and manufacturing cost is high.
The content of utility model
The purpose of the utility model provides the emanant anode film reactor unshakable in one's determination of poured with epoxy resin insulated type of a kind of simple in structure, low cost of manufacture, function admirable.
In order to reach above-mentioned requirements; The utility model is realized through following scheme: it includes the circular coil with the tubular guidewire electric material coiling of intermediate hollow; It is characterized in that two involutory U-iron hearts being installed in the both ends of the surface of coil; The both ends of the surface of the U-iron heart are provided with air gap, form one group of iron core, many groups are installed on whole circular coil are the iron cores that radiation distributes; In the space of U-iron heart institute obvolvent coil, fill and be cast with epoxy resin, in the outside of iron core through special-purpose belt tensioner with iron core and coil obvolvent.
Described tubular guidewire electric material is copper pipe or aluminum pipe.
The emanant anode film reactor unshakable in one's determination of poured with epoxy resin insulated type according to such scheme is made has compact conformation, and advantages of small volume, cooling are rationally; Make and characteristics easy for installation; Especially through the cast of epoxy resin, make every circle coil stationary in epoxy resin, reduced noise effectively; Reduce leakage field, improved the ability of bearing surge current.
