量で表わされている。 In general, the shield circuit breakers used in ultra-super high voltage conduits employ a closing resistance method to reduce the insulation level of the conduit, as shown in the electrical circuit diagram shown in Figure 1. That is, it is common to connect several arc extinguishing chambers (four in the example) in series and disconnect them, and the arc extinguishing chamber section 3 is connected in parallel with a closing resistance contact section 4 and an impedance for voltage sharing. are doing. Impedance 5 is represented by capacitance.

ン諏を分散して配置する構成もある。 In the tank of such a disconnector or a disconnector, a closing resistance contact part 4 and a voltage sharing impedance 5 each are formed in a substantially cylindrical shape with respect to the central axis of the arc extinguishing chamber part 3 which is formed in a substantially cylindrical shape. The central axes of the two were arranged on the same plane. In this arrangement, the ground electric field of the closing resistance contacts and voltage sharing impedance placed at both ends of the wall of the approximately cylindrical tank that houses these becomes severe, so it is necessary to increase the tank diameter to alleviate the electric field. Become. If the diameter becomes larger in this way, since the tank is a pressure vessel, the thickness of the tank becomes thicker in proportion to the diameter, resulting in higher prices and a larger installation space. Mikiakiaki again
As known from Publication No. 50-54556, only the arc extinguishing chamber is arranged concentrically with the central axis of the tank, and the closing resistance contact and the voltage sharing impedance are distributed and arranged near the arc extinguishing chamber. There is also a structure.

にある。 However, even in this configuration, the circle circumscribing the arc extinguishing chamber, the closing resistance contact, and the voltage sharing impedance is not coaxial with the tank;
Therefore, the closing resistance contact and the voltage sharing impedance become protruding parts, and the electric field strength locally increases.
As in the previous embodiment, the tank diameter becomes larger as a result. SUMMARY OF THE INVENTION An object of the present invention is to provide a highly reliable tank-type packer or disconnector that can reduce the diameter of the tank by uniformizing the electric field of the shield or disconnection part to the tank, and therefore can reduce the installation space. There is a particular thing.

行して配置される。 The present invention will be described below with reference to an embodiment shown in FIGS. 2 and 3. The same parts as in FIG. 1 are given the same symbols. In FIG. 2, a tank 1 is provided with a nozzle stub 2, and the central axes X and X' of this nozzle stub 2 are formed perpendicular to the central axis of the tank 1. An insulating tube 11 provided concentrically inside this nozzle stub 2 supports an arc extinguishing chamber 3 and a closing resistance contact 4 that constitute a break section, and a voltage sharing impedance 5 is supported by a support (not shown). are installed and supported in parallel to the arc extinguishing chamber section 3 by the. Here, the arc extinguishing chamber section 3, the closing resistance contact section 4, and the voltage sharing impedance 5 forming the cross section are each formed into a substantially cylindrical external shape as shown in the illustrated cross section. Ru. The arc extinguishing chamber section 3 includes a puffer arc extinguishing chamber (not shown), and the closing resistance contact section 4 also includes a closing resistor and a contact (not shown). The three members are arranged parallel to each other so that their axial directions are the same as the axial direction of the tank 1.

うに三者を配置してある。 The arc extinguishing chamber section 3 and the closing resistance contact section 4 are parallel to each other, and an imaginary line drawn connecting their central axes is approximately perpendicular to the axial direction of the insulating rod 6. That is, an imaginary line drawn connecting the central axes is approximately parallel to the Y and Y' lines shown in the drawing. On the other hand, the voltage sharing impedance 5 is arranged in a portion located above the imaginary line so that its axial direction is parallel to the arc extinguishing chamber 3. Therefore, if the central axes of the arc extinguishing chamber 3, the contact section 4, and the impedance 5 are connected, these three will be located at each vertex of the triangle. The center of a circle 12 indicated by a dotted line in the figure that circumscribes these three members almost coincides with the center of the tank 1. In other words, the three members are arranged so as to be almost inscribed in a circle drawn concentrically with the tank 1.

クを作ることができる。 By arranging the three parts in this way, the ground electric field of one of the three parts, for example, the contact part 4, will not become extremely large, and the built-in parts in the tank 1, i.e., the whole section, will not become extremely large. Since the electric field distribution is uniform, there are no weak points. Therefore, it is possible to reduce the diameter of the tank, and since it is a pressure vessel, the reduction in diameter affects the reduction in plate thickness, making it possible to manufacture a tank at low cost.

動部より負荷が大きい為合理的である。 FIG. 3 is a detailed view of the link mechanism section 101,
Insulating rod 6 interlocked with a drive unit (not shown)
A drive rod 20 is connected to the movable part of the arc extinguishing chamber 3 via a link 7, which rotates a connecting shaft 8 extending from both sides of the link 7, which is disposed in a direction orthogonal to the rod 6, and again via links 9 and 10. and the drive rod 21 connected to the movable contact part of the closing resistance contact 4 are operated in conjunction with each other. For a distance l 1 along the connecting shaft from link 7 connected to insulating rod 6 to link 9 connected to the movable part of arc extinguishing chamber 3, from link 7 connected to insulating rod 6 to link 9 connected to the movable part of the closing resistance contact. The arc extinguishing chamber portion 3 and the contact portion 4 are arranged such that the distance l 2 along the connecting shaft to the link 10 satisfies l 1 <l 2 . Generally, the diameter of the arc extinguishing chamber 3 is larger than the diameter of the closing resistance contact 4, so if it is arranged as shown in Figure 2, l 1
<l 2 . This is reasonable because, from the point of view of mechanical stress, the load on the movable part of the arc extinguishing chamber is always greater than that of the movable part of the closing resistance contact.

点検の際高所作業の危険性も軽減される。 As explained above, according to the present invention, the arc extinguishing chamber and the making resistance contact are arranged in parallel, and a triangle is drawn with the line drawn connecting the center axes of the arc extinguishing chamber and the making resistor contact as its base. The voltage sharing impedance is arranged in a triangular arrangement parallel to the arc extinguishing chamber so that the center axis of the voltage sharing impedance is located at the apex of the tank. Since it is arranged so that it almost coincides with the center of the tank, the ground electric field of the three parts can be made uniform, which is very reasonable in terms of the electric field. Therefore, the diameter of the tank is about 75% of that of the conventional type tank. It can be done. This smaller tank diameter means that it is a pressure vessel, so the tank thickness will also be reduced by 75mm.
%, so it is possible to create a very low-cost tank (about 56% of the cost of conventional tanks). Furthermore, since the diameter of the tank is smaller, the installation space is also reduced, and the danger of working at heights when assembling and inspecting the breaker is also reduced.
