Description
Technical field
The utility model relates to reactor, particularly a kind of direct-current transmission converter valve saturable reactor.
Background technology
The direct-current transmission converter valve saturable reactor is the critical component of super extra-high voltage direct-current transmission engineering thyristor converter valve; can be used to reduce the surge current climbing of converter valve; suppress the converter valve voltage build-up rate under thunder and lightning, the steep wave; and converter valve played all pressure effects, to reach the purpose of protection converter valve.
Existing direct-current transmission converter valve saturable reactor generally all is to adopt iron core and one group of multiturn coil lotus root to close to form.The saturable reactor for converter valve that designs at different electric pressures, because coil has only one group, the inductance value that the sheet number by regulating iron core and the number of turn of coil are regulated whole reactor jointly, therefore, the overall dimension of reactor is difficult to control, the size of corresponding water-cooled cooling device is difficult to realize standard configurations, makes troubles for the modularized design of converter valve components.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, direct-current transmission converter valve saturable reactor of making things convenient for modularized design.
In order to reach above purpose, the utility model takes following technical scheme to be achieved: a kind of direct-current transmission converter valve saturable reactor, comprise support, iron core and coil, and it is characterized in that, described iron core is the paired U type structure of snapping up and down, fixes by band; Described coil is two groups, and coupling is assemblied in two arms of described iron core respectively.
Novel further characteristics and the improvement of this practicality is:
Be provided with the air gap pad between the U type structure of the paired snapping up and down of described iron core.
Described iron core is a plurality of, successively parallel arranged; It further improves and is: be provided with water-filled radiator between described iron core.
Described support comprises two frameworks, and the top and the bottom of described two frameworks are fixedly connected with insulating end plate.
Iron core of the present utility model is the paired U type structure of snapping up and down, is provided with the air gap pad between the U type structure of snapping up and down in pairs, and the thickness that changes the air gap pad can be regulated the inductance value of reactor; Iron core is a plurality of, and parallel arranged can reach the purpose of regulating inductance value by changing the number of iron core successively; At last, change the number of turn of coil, also can regulate the inductance value of reactor.Above-mentioned adjusting can be used separately, also can comprehensive adjustment, and to satisfy the fine setting of reactor inductance amount or adjust therefore significantly, the reactor design to the different induction amount only needs modular adjustment, does not need structuring to change.Simultaneously, support of the present utility model adopts two frameworks, insulating end plate fastening, conveniently increases or reduce the iron core number; Adopt a plurality of iron cores, help the heat radiation of reactor, and be provided with water-filled radiator between a plurality of iron core, radiating efficiency is higher.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the direct-current transmission converter valve saturable reactor, comprise coil 1 that cast is good in advance that is arranged between support 11, bottom insulation end plate 7 and the top insulating end plate 4 and the iron core 2 that assembles with coil 1 coupling, iron core 2 adopts U type structure up and down, make-up is between the inside and outside wall of coil 1, separate with air gap pad 13 between the U type structure of two make-ups of iron core 2, fix with the stainless steel band then, separate with dividing plate 12 between each iron core 2, and dispel the heat with a water-filled radiator 13 between per two iron cores 2.Whole reactor adopts water-cooling, and water-main 9 and distributive pipe 10 all are arranged in the connection bus 6, and the cooling water pipe 14 of water-filled radiator 13 finally is connected to distributive pipe 10 places with the cooling water pipe of coil 1, also can directly arrive distributive pipe 10 places.In order to draw the damping loss heat of iron core 2, set up a heat sink resistance 8 and circle heat radiation coil, the solderless wrapped connection from the arm of iron core 2 of described heat radiation coil comes out to connect with heat sink resistance 8, and heat sink resistance 8 is fixed between connection bus 6 and the bottom insulation end plate 7.Iron core 2 preferably adopts high frequency characteristics good, the 0.1mm grain-oriented silicon-iron strip of annealed processing.
The coil 1 standard number of turn of present embodiment is 8 circles, but also can adopt 6 circles, 7 circles or 9 circles, and iron core 2 is traditionally arranged to be 4, also can preferentially be adjusted into 2 or 6 according to concrete numerical value, but also can adopt 3 or 5, and is uneconomical greater than 6.Certainly, special requirement also can be adopted 1 iron core 2 of make-up U type structure up and down.
The modular designs scheme that present embodiment adopts, saturable reactor satisfy the parameter variable quantity little in, just can finish design, make by the number of turn of regulating winding and the thickness of iron core air gap pad, can not change the overall dimension of coil this moment, and the overall dimension of every pair of iron core does not change yet simultaneously.When satisfying inductance value and change big designing requirement, the main saturable reactor that produces different electric pressures and different parameters requirement with the number of turn (profile of coil can be constant at this moment) that changes coil among a small circle that cooperates by the number of regulating iron core.
According to above mentality of designing, it is constant relatively to design the coil shape size, and the overall dimension of iron core is constant relatively, the saturable reactor form that overall dimension is comparatively fixing.Therefore, do not need other design and installation size generally speaking, changed the problem of the sort of in the past complex structural designs that causes because the reactor overall dimension of different induction amount is different fully, saved a large amount of time for the design process of converter valve components, the production of saturable reactor can be carried out in batches, the delivery cycle that shortens has guaranteed the consistency of product quality.
