Abstract
The utility model relates to an air-cooled silicon-controlled valve string structure, which comprises silicon-controlled thyristors and radiators, wherein the silicon-controlled thyristors and the radiators are superposed in pairs at intervals and are combined into a silicon-controlled valve string through two threaded rods inserted on the radiators; and the two ends of each threaded rod are provided with a fixed pressure block and a sliding pressure block respectively. As the plate type radiators and the silicon-controlled thyristors are combined at intervals into a valve string structure, the air-cooled silicon-controlled valve string structure not only can directly utilize natural wind to directly radiate thyristor groups, but also needs no special equipment to maintain the equipment due to simple structure.
Description
Technical field
The utility model relates to silicon-controlled device, especially a kind of air-cooled thyristor valve string structure.
Background technology
The power electronic technology fast development of twentieth century end, comprise that the components and parts manufacturing technology has had tremendous development, represent the main electric characteristic V parameter of controllable silicon (SCR) device DRM/VRRM, IDRM/IRRM, dv/dt, di/dt, VT, tq, Qrr parameter to increase substantially, dispersiveness reduces greatly, particularly be diffused as the manufacturing technology of representative with quadruple, if make the dispersiveness of element Qrr be controlled at about 1%. a plurality of thyristors are together in series, just can be applied in the mesohigh electric power system.How but the main difficult technical that faces selects the suitable insulation structure and the type of cooling if being (1), (2) how effectively improve the functional reliability of a plurality of element connected in series, (3) how simplified structure reduces the failure factor that may occur, reduce volume as far as possible. in view of above-mentioned difficult point, the thyristor valve string of market-ripe application now is considerably less, also very immature. usually, the thyristor valve string adopts water-cooling pattern to solve heat dissipation problem.
The utility model content
The purpose of the present utility model: aim to provide a kind of cascaded structure controllable silicon scheme of can through engineering approaches using, safe and reliable operation that can ensuring equipment, have simultaneously the characteristics of small size, low cost, minimizing maintenance again, thereby enlarge the application of high-voltage thyristor.
Technical solution of the present utility model is:
This air-cooled thyristor valve string structure, comprise silicon controlled crystal brake pipe, radiator, be characterised in that: described silicon controlled crystal brake pipe and radiator are combined into the thyristor valve string with paired at interval form two screw rods stacked and through being set on the radiator one by one, the two ends of described screw rod are respectively equipped with fixedly briquetting and wiper block, and are provided with set screw on described wiper block.
Described radiator is a panel radiator.
Described screw rod ectosome is provided with insulating coating.
This air-cooled thyristor valve string structure according to above technical scheme proposition, form the structure of valve string shape each other at interval owing to adopt panel radiator and silicon controlled crystal brake pipe, therefore not only can directly utilize natural wind that thyristor groups is directly dispelled the heat, and because the structure realization simply, need special equipment can finish the maintenance of this equipment.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1-is briquetting 2-silicon controlled crystal brake pipe 3-radiator 4-screw rod 5-washer type briquetting 6-dish spring 7-set screw 8-wiper block fixedly
Embodiment
This air-cooled thyristor valve string structure as shown in the figure, comprise silicon controlled crystal brake pipe 1, radiator 2, be characterised in that: described silicon controlled crystal brake pipe 2 and radiator 3 are combined into the thyristor valve string with paired at interval form two screw rods 4 stacked and through being set on the radiator 3 one by one, the two ends of described screw rod 4 are respectively equipped with fixedly briquetting and wiper block, and are provided with set screw on described wiper block.
Described radiator is a panel radiator.
Described screw rod ectosome is provided with insulating coating.
The utility model is being by will inserting and putting the silicon controlled crystal brake pipe of radiator between many, every adjacent two silicon controlled crystal brake pipes, with the screw rod use that is together in series.The upper and lower side of screw rod 4 stretches out the radiator at two ends, the upper and lower end of screw rod 4 and Aluminium Radiator 3 usefulness fixedly briquetting 1, washer type briquetting 5 and wiper block 8 fix smooth, pack into screw rod 4 with butterfly set screw 7 then and screw briquetting 8, form complete natural air cooled heat radiation thyristor valve string.
Above-mentioned said radiator 3 preferably selects for use material to be: aluminium section bar
According to said structure, as adopt annexes such as two groups of silicon controlled crystal brake pipes 2 and corresponding Aluminium Radiator 2 can form the natural air cooled heat radiation thyristor valve of 3KV high pressure string; As adopt annexes such as five groups of silicon controlled crystal brake pipes 2 and corresponding Aluminium Radiator 2 can form the natural air cooled heat radiation thyristor valve of 10KV high pressure string; As adopt annexes such as eight groups of silicon controlled crystal brake pipes 2 and corresponding radiator 2 can form the natural air cooled heat radiation thyristor valve of 15KV high pressure string; Above-mentioned composition can adapt to the soft start demand of the big motor of high pressure.
1. in natural air cooled heat radiation thyristor valve string structure, the screw rod of handling through High-Voltage Insulation is connected into all heat-radiator plates and controllable silicon a string.After this valve was connected in series mesohigh (3-15KV) electric power system, the insulation system of integral valve string can satisfy the demand of field working conditions fully;
2. the valve string is inner under conducting state, and thermal losses can take place, and the generation of thermal losses directly causes device junction temperature to raise.When junction temperature was elevated to above rated junction temperature, the breakover voltage of thyristor sharply descended, and made the leakage current under blocking-up and the reverse state sharply increase thus, and the device blocking ability descends, even causes device failure.
3. common, the thyristor valve string adopts water-cooling pattern to solve heat dissipation problem. and the natural air cooled heat radiation thyristor valve of the high pressure that we provide string utilizes natural air cooled mode to resolve the solution heat dissipation problem on the basis of considering thermal losses, radiator conductive coefficient, radiator area;
Controllable silicon clamps mounting arrangements by special panel radiator in-line, and structure realizes simple, repairs very simple and easy. and do not need special installation can finish maintenance work. the utility model has the advantages that: simple in structure, with low cost, easy for operation.Use by many controllable silicon series connection, solved the limitation of present semiconductor device, have withstand voltage height, strong shock resistance, moving static state voltage equipoise effect stability, long service life, safe and reliable to operation in the high-voltage applications field.
