    This invention relates to the field of electrical engineering, in particular, to high voltage thyristor NEL modules with liquid cooling.
    Thyristor models with series-connected thyristors are used for high voltage, for example, for static high voltage converters. When constructing such a module, it is necessary to take into account electrical conditions, such as voltage distribution, insulation and luminescence barrier, as well as mechanical design, and this should be taken into account from the point of view of strength, practicality and relative compactness. It is also necessary to take into account cooling conditions - safe and uniform cooling of all thyristors. In the case of tablet thyristors, which are currently most commonly used for high power and voltages, two-sided cooling of the thyristors is used.
    A liquid-cooled thyristor module is known, containing a plurality of tablet thyristors alternating with electrically conducting radiator and through which fluid passes. The entire module is compressed using a common clamping device that creates the necessary pressure between the thyristors.
    In such a device, replacing one of the failed thyristors is a difficult task: it is necessary. To remove the entire module. In addition, separate cooling circuits are provided for each radiator, which is a complicated and expensive cooling method.
    The closest technical solution to the proposed is a high-voltage liquid-cooled thyristor module containing a plurality of series-connected tablet thyristors, electrically connected radiators are located on the anode and cathode sides of each of which, the radiators of neighboring thyristors are interconnected by means of coolant tubes, a part of which is made of an electrolysis material, so that the cooling of the thyristors with the anodic and cathodic it is performed in parallel streams zhidkoeti H.
    In this device, when connected in series, radiators from both the anode and the to-anode sides are interconnected to the full area of the electrical insulating tube; there is a danger of a coolant leaking at the joints. In addition, since the cooling tubes do not electrically connect the thyristors, it is necessary to provide separate electrical wires, which increases the risk of poor connections, which can lead to malfunction of the entire module. All this leads to a lack of reliability of the module.
    The purpose of the invention is to increase reliability.
    The goal is achieved by the fact that in a high-voltage liquid-cooled thyristor module containing a plurality of series-connected tablet thyristors, electrically connected radiators are located electrically with them on the anode and cathode sides, while the radiators of neighboring thyristors are interconnected by means of cooling tubes. part of which is made of electrically insulating material, such that the cooling of the thyristors from the anodic and cathodic sides is performed parallel to Liquid, radiators, located on the anode side of each previous thyristor, with the exception of two thyristors at the end of a series connected, are connected to a radiator located on the cathode side of the subsequent thyristor, using electrically conductive coolant tubes, the thyristors are electrically connected, and the radiators dispersed on the cathode side of the preceding thyristor are connected to the radiator located on the anode side of the subsequent thyristor oizol tional tubes for .ohlazhdayuschey liquid. In addition, electrically conductive tubes for cooling fluid between radiators are surrounded by magnetic cores. The voltage divider elements are connected to electrically conductive coolant pipes or radiators. One of the radiators of each thyristor is rigidly attached to a single supporting element and electrically isolated from it, and the thyristor and the second radiator of each thyristor are attached to the first radiator using a removable holder. The elements of the voltage divider are located on the support element. The supporting element is provided with a screen. Electrically conductive and electrically insulating coolant tubes are located crosswise between the heatsinks of neighboring thyristors. In FIG. 1 schematically shows a thyristor module; in fig. 2 - separate modules when assembled into a valve in FIG. 3 - module option. FIG. 1 shows a series of serially connected thyristors 1-4. Thyristors have a tablet form / from two sides (anodic and cathodic) cooling radiators 5 and 6, respectively, through which the liquid flows and which simultaneously form electrical compounds for the anode and the cathode of the thyristor. The radiator b on the cathode side of the thyristor is connected in series with the radiator 5c of the anodic side of the subsequent thyristor using an electrically conducting tube 7 for the cooling tube 7 for the coolant. Moreover, the same radiator 6 with the cathode side is connected to the radiator 5c of the anodic side of the previous one, the thyristor by means of an electrically insulating tube 8 for cooling liquid. In this way, the thyristors are cooled by two parallel flow of fluids, which constantly intersect each other and in which each second connection also forms an electrical connection between the thyristors. If the fluid flows towards each other, then all the thyristors are evenly cooled. Two fluid streams can be connected in series, as shown by the dotted line on the left end of the lamp. Radiators 6 are placed on the cathode side with a single support on the element 9, which can be insulating or insulated, or an insulating gasket 10 can be placed between the radiator and the supporting element 10. The thyristor and its two radiators 5 and 6 are attached to the supporting element 9 by means of -the holder, or clamp (conventionally indicated by the arrow 11). Each thyristor is attached to its holder, so you can replace a blown thyristor, do not disassemble the entire module. In thyristor modules, for a high voltage between the thyristors, reactive coils are connected to control the derivative of the current in the module and the individual thyristors during ignition and quenching. In this construction of the module, this is achieved in a simple way by fitting the iron cores 12 onto the conductive tubes 7, for example, in the form of intact or split ring-shaped cores. In order to ensure correct voltage distribution in the module and to power thyristor ignition devices (not shown), the module is connected via a resistive-capacitive voltage divider (shown schematically as a combination of series-connected capacitors 13 and resistors 14). The latter is connected in such a way as to provide cruciform connections with conductive cooling tubes 7. Support element 9 forms a corresponding frame in which elements 13 and 14 can be placed, as well as ignition devices for thyristors. Liquid from radiators can be passed to cool thyristors 14, the cooling requirement of which is not as critical as to thyristors. Connections 15, 16 of the module can be combined with the connection to the voltage divider elements 13,14. A high voltage module should usually be provided with a device.
