Description

The invention relates to a well known in electrical engineering a distributor with a metallic reserve pool for accumulating gases. The arrester is equipped with a radially disposed metal partitions-ribs.

Basically auth. St. L 51350 oinsay and discharge of DNA, which has a reservoir at the end of the tube for extracting in it an excess of gas produced by the decomposition of the fiber under the action of a volt arc. The gas accumulated in the reservoir forms a de-ionizing spark blowing space during the passage of current through the bullets, and thereby prevents further current flow through the discharge.

The proposed arrester is distinguished by the fact that there is a sterile electrode in it. It is completely hollow, in the form of an open tube in the form of an open air tube with oblique holes in the area of the reservoir. With these holes, gases are sucked from the reservoir and discharged through the open end of the electrode into the spark plug, which causes the dololiteline deionization of gases in the spark gap. In the discharge, the radially arranged metal partitions-ribs can be made wavy or provided with small pieces and holes.

The fibrobakelite tube / and 2 and at one end is provided with a reserve for gas accumulation, and on the other m - electrode M 5 with an exhaust hole. The second electrode is made in the form of a tube 4, fixed in the bottom of the tank and having three or four obliquely arranged holes in the tank area 5. A metal plug is inserted into the channel of the tube 4 at the bottom of the tank, ending at the first of the holes 5.

Radially located wavy ribs 6 made of sheet metal and provided with small holes are welded to the metal walls of the tank with three points. The tank with wavy ribs 6 forms a deion chamber.

The presence of longitudinal wavy ribs in the reservoir creates favorable conditions for cooling the hot gases entering the reservoir from the arc burning sphere. Cooling of post-uenium gases allows, at the same pressure, to accumulate more gases in the deionic chamber. This cooling will be especially effective at low currents, when the temperature of incoming flows is relatively low.

The transition ring 7 is made of aluminum, and ne of l-iron, as is usually done. By making the colp 7 of nonmagpered material, there is local resistance to the gas flow from the gap to the deionic chamber through the ring 7 during the time of arcing. Local sonic resistance is caused by the interaction of the flow of an ionized gas of a magnetic field, created by a current that flows through the tube 4.

When a lightning strikes a transmission line, an overvoltage wave causes a tiny hole in the gap (between electrode 5 and tube electrode 4), an arc occurs, but with which a short-circuit current begins to flow. Under the action of the arc, fiber 2 n-intensively produces gas that is partially discharged through the exhaust port of electrode 3, creating a blast, and partially flowing into the tank, where it is accumulated and deionized.

The surface contact of the metal with gases contributes to more intensive deionization of the incoming gases. Thus, in the deion chamber, a large amount of gases are produced, the most stable and on the most deionized, i.e. the most electrically stable.

With the passage of the nerve half-wave of the short-circuit current through zero, a powerful stream of gases from the deion chamber to the exhaust port, i.e., an intense longitudinal blast, begins.

The rapid flow of gases along the fibrobakelite tube / and 2 causes gas to be sucked through the openings 5 into the internal channel 8 of the electrode (tube) 4. This gas will be a rapid stream from the end of the electrode (tube) 4 and break up the source of discharge that occurs At the end a conventional massive rod electrode in the form of ionized gas particles accumulated in a cone-shaped dead zone.

Besides; the gases inside the narrow channel 8 of the electrode 4 will be even more electrically strong, and the presence of this additional exhaust gas accelerates the exhaust process.

G1rsd; The agae gadget design provides a significant reduction in the lower limit of the switchable currents without affecting the upper one, since the upper limit of the currents is limited by the diameter TpyoKi ;. Since it is especially important for a 110 kV line arrester to reduce just the lower limit of the switchable currents, the proposed bit for these use cases has significant advantages over the known ones.
