Abstract
The utility model discloses a double-rail type iron core anode saturation resistor, aiming at providing a double-rail type iron core anode saturation resistor which has compact structure, low manufacturing cost and excellent property. The double-rail type iron core anode saturation resistor comprises a runway-shaped coil which is coated with high-molecular insulating materials on an outer surface, provided with a hollow middle and wound with tubular winding wires, wherein two involutive U-shaped iron cores are arranged on both end surfaces of the runway-shaped coil; both end surfaces of each U-shaped iron core are provided with air gaps to form a group of iron cores; a plurality of groups of iron cores are arranged on two straight ways of the integral runway-shaped coil, and the iron cores are externally clamped with the runway-shaped coil through tightening belts. The double-rail type iron core anode saturation resistor disclosed by the utility model has the characteristics of compact structure, small size, reasonable cooling and convenience for manufacture and installation.
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 biserial rail mounted anode film reactor unshakable in one's determination of a kind of compact conformation, low cost of manufacture, function admirable.
In order to reach above-mentioned requirements; The utility model is realized through following scheme: it is characterized in that it includes the racetrack-type rotor coil with the tubulose coiling coiling of outer surface coated high molecular insulating material intermediate hollow; Both ends of the surface at coil are equipped with two involutory U-iron hearts, and the both ends of the surface of the U-iron heart are provided with air gap, form one group of iron core; It is unshakable in one's determination that many groups are installed on two straight ways of whole racetrack-type rotor coil, passes through belt tensioner with iron core and coil obvolvent in the outside of iron core.
It is unshakable in one's determination that the 10-20 group is installed on described two straight ways altogether.
Biserial rail mounted anode film reactor unshakable in one's determination according to such scheme is made has compact conformation, and advantages of small volume, cooling are rationally made and characteristics easy for installation.
