    In order to avoid taking leads through the envelope (1, 2) the electrode of the voltage transforming capacitive part comprises an intermediate piece (3) insulated and tight to the pressure gas, inserted in the envelope. This piece comprises, outwardly, an insulating material coating (9) and a metal layer (10) on said coating. The three (3, 9, 10) form a support for the current transforming cores (11) wound with the secondary winding. The low voltage between the intermediate piece (3) and the metal layer (10) is led by an armoured measuring able (12/12a) of an electronic measuring amplifier (14). The current transforming cores (11) are mechanically protected by a cylindrical screen which, at the same time, leads the envelope currents.

    专利说明:

    gaskets are made as a single element. . Measuring high-voltage transformer is equipped with a casing in the form of a metal coarse, mounted on the flags of the two parts of the body. The condenser is connected to the intermediate part and the metal coating. FIG. 1 shows a transformer, a cut; in fig. 2 — node 1 in FIG. one; in fig. 3 - variant with respect to the measuring cable supplied to the amplifier of the measured voltage. The transformer contains between parts 1 and 2 an isolated intermediate piece 3, which has practically the same internal diameter, as well as the wall thickness, as the housing. Parts 1-3 are made from light metal, such as aluminum or doped with them. Conductive Vyvokoy voltage conductor 4 current contained within parts I and 2 of the housing, isolated in a known manner. The inner part of the housing is filled with compressed gas, for example sulfur hexafluoride. Between part 1 of the housing and intermediate part 3 there is a pressure ring 5, seals 6, insulating parts 7 and 8, and the insulating part 8 of the pressure ring 5 isolates from the intermediate part 3. The pressure ring: 5 and the body 1 are mutated with a flanged bolt joint. If the pressure ring 5 is not made of metal, but of reinforced insulating plastic, then the insulating part 8 can be eliminated, if necessary, in order to simplify the design. Simplification is also achieved if the insulating part is ticked, adjacent seals 6 are made as a single part. In this case, predominantly insulating parts are made in the form of extruded parts from plastic with good mechanical and electrical properties. The intermediate piece 3 has on its outer side a layer of insulating substance 9. The latter is wound mainly from a thin plastic film with good electrical properties on the intermediate piece 3. The metal coating 10 is applied on the outer surface of the insulating layer 9, It can consist mainly of copper mesh, reusable in transformer constructions, which is covered with a stitching substance and wound on an insulating layer. Parts 3, 9 and 10 serve as a non-drying case for enclosed cores 11 current transformers. The positions are fixed on the metal coating 1O using insulating intermediate spacers (not shown) using additional bandages and secured by means of a putty that dries in air. The lengths of parts 3.9 and 10 are so selected that they can accommodate a large number, for example, five, current transformer cores 11. In this case, measuring and protective cores with different loads and accuracy classes can be used, due to which different core lengths are obtained. While. For parts of a voltage transformer, a high voltage capacitance is created using a natural capacitance between the current conductor 4 and intermediate part 3, the low voltage capacitance is summed up from a variety of private capacitances, namely the capacitance between parts 3 and 10, the capacitance of the measuring cables 12 and Additional The capacitor 13 as well as the capacitance between the parts 3 and 5. With the help of an additional capacitor it can be equalized, depending on the place of installation of the capacitive parts and the measuring amplifier, the length of the measuring capacitor is different. I ate from the viewpoint also of different capacities. Due to this, as well as the choice of a certain temperature coefficient of the optional condenser 13, for the ratio of high voltage to low capacitances, greater accuracy can be achieved within a large temperature range. FIG. 1 armored measuring cable 12 single. Its shell is connected to the metal cover 10 and to the kshts of the additional capacitor 13 and is grounded through it. FIG. 3 armored measuring cable 12 strong. Due to this, it is possible for one liquid to isolate the measuring amplifier 14 in isolation. As an electronic measuring amplifier, a conventional amplifier is used with an output of 15. An additional capacitor 13 can be connected to a protective voltage transformer to prevent it (not shown ). FIG. Figure 3 shows that the additional capacitor 13 and the capacitance between the degals 3 and lO can be included in the feedback loop of the measuring amplifier 14. With the help of a metal tube 16 in the form of a casing, connecting longitudinally parts 1 and 2 of the housing. one side, mechanically protected, and on the other hand, these ensured that the currents and parts 1 and 2 of the case do not have any distorting effect on the measurement current. The invention 1. Measuring high-voltage current and voltage transformer, containing a sealed metal housing with a high-voltage winding passing inside it, filled with compressed gas and made of two parts with flanges, sealing elements, cores with metal windings wound on them, windings on them, forming with the high-voltage winding a single capacitor of a voltage divider, a capacitor and an amplifier, characterized in that, in order to increase the reliability of operation, it is equipped with isopulating Metal-covered emendment, armored cable, intermediate part with sealing elements installed between two parts of the housing, on the intermediate part there is an insulating element with a metal coating, next to the intermediate part, another capacitor of the voltage divider, mounted on the cahors / EN heart winding hooks, armored cable is connected with a metal-coated interstitial part with a capacitor and amplifier, 2, the transformer according to claim 1, which is due to the fact that the sealing elements cients are formed as insulating parts, with: egakltsyus thereto gaskets and pressing Kt ltsa for connection with the housing. 3, Transformer according to claim 2, which is based on the fact that the pressure ring is made of plastic; 4, Transformer according to claim 1, 1, which is insulated by isolating the parts with plaster liners made of one element , 5, The transformer according to claim 1, 1, about tl and - due to the fact that it is equipped with a casing in the form of a metal pipe mounted on the flanges of two parts of the housing. 6, Transformer according to claim 1, 1, and tp and the fact that the capacitor is connected to the intermediate part and the metallic core.
