    摘要： The invention deals with a quenching chamber applicable in medium-voltage switch disconnectors. The quenching chamber (1) comprises a body (11, 11') made of a gassing material. The body (11,11') is a solid of a shape similar to a rectangular prism having a top wall (2, 202), a bottom wall (3, 203), a front wall (4, 204), a back wall (5, 205) and side walls (6, 206). The chamber comprises an arcing knife channel (17) and an arc chamber (22) hollowed in the body (11, 11') and it is fitted with an arcing contact unit (19) located in a socket (18). The quenching chamber is characterized by the fact that the arc chamber (22) extends directly along the arcing knife channel (17), from the back wall (5, 205) of the chamber (1) and it is connected with the inside of the arcing knife channel (17) through a gap of a width of (s), forming a flat funnel. The height of the funnel (h) in a plane parallel to the surfaces of the side walls (6, 206), decreases with an increase in the distance to the arcing knife channel (17). The width (s) of the gap in a plane perpendicular to the surfaces of the side walls (6, 206) is less than the width of the arcing knife channel measured in a plane perpendicular to the side walls (6,206) of the body (11,11').

    摘要翻译： 本发明涉及一种适用于中压隔离开关的淬火室。 淬火室（1）包括由放气材料制成的主体（11,11'）。 主体（11,11'）是与具有顶壁（2,202），底壁（3,203），前壁（4,204），后壁（4,204），后壁 （5,205）和侧壁（6,206）。 所述腔室包括弧形通道（17）和在所述主体（11,11'）中空的弧形室（22），并且所述电弧室配备有位于插座（18）中的电弧接触单元（19）。 淬火室的特征在于，电弧室（22）从腔室（1）的后壁（5,205）直接沿着电弧通道（17）延伸，并且其与内部的 电弧通道（17）通过宽度（s）的间隙形成扁平的漏斗。 漏斗（h）在与侧壁（6,206）的表面平行的平面中的高度随着与电弧刀通道（17）的距离的增加而减小。 垂直于侧壁（6,206）的表面的平面中的间隙的宽度小于在与主体的侧壁（6,206）垂直的平面中测量的电弧刀通道的宽度（ 11,11' ）。

    摘要： The subject of the invention is a rotary switch-disconnector with a double, serial clearance during the disconnection of electric contacts. A rotary switch-disconnector comprises a rotary shaft (1) with at least one bushing (2) with main movable contacts (12) and movable arcing contacts (13), located at the ends of the body (10) of the bushing (2). The frame (3) has attached to it at least one pair of piston insulators (6) containing main fixed contacts (14) placed on the line of revolution of the main movable contacts (12), and fixed arcing contacts (16). Each piston insulator (6) contains a cylinder (7) with a piston (8) which through a tension member (9) is connected in an articulated way with the body (10) of the bushing (2) in a way ensuring a simultaneous movement of the pistons (8) in the cylinders (7) with the revolution of the shaft (1). The inventive switch-disconnector is characterized in that the piston insulator (6) has attached to it a blow-out nozzle (17) comprising a blending chamber (19), a central channel (20) and at least one side channel (22) used to supply and swirl air in the blending chamber (19) when the switch-disconnector is being opened, which chamber is so situated in relation to the piston insulator (6) that the inlet(s) (W1) of the sides channels (22) is(are) connected with the outlet(s) (W3) of internal channels (23) which are connected with the inner surface of the cylinder (7) and are located outside the limits of the inlet (W4) of the movable arcing contact receiving channel (18) which is made in the piston insulator (6).
