Description of the invention (1) [Application fields in the industry] (Please read the precautions on the back before filling out this page) The present invention relates to circuit breakers, especially to the structure of contacts. 〔Known Technique〕 Although a circuit breaker, which is a constituent element of a gas-insulated switchgear, opens and closes a short interval from the circuit breaker to the circuit breaker, the circuit breaker is usually opened by a specific ratio. The device opens and closes at a very slow speed. Therefore, based on the potential difference between the voltage remaining on the load side and the voltage that changes at the commercial frequency of the power source side across the contact, the arc will repeat on the pole side. Finally it will open or close. As reported in the Technical Report of the Institute of Electrical Engineering (C α) No. 324 “Insulation Problems of Severe Surge GIS” (page 17), there may be arc bifurcations to the ground when the poles are bridged by the re-arc and the arc is bridged. The phenomenon of discharge. In order to prevent this, a design has been adopted in which the re-arc is as close as possible to the movable contact between the contacts and the electrode shape of the contact. [Problems to be Solved by the Invention] Although printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs, a sudden surge may occur depending on the re-arc when the circuit breaker is opened and closed. However, in order to suppress this, a method of re-arc via a resistor is used. The resistor contact has a structure that re-arc between the movable contact and the movable contact has a cylindrical shape. A substantially central portion of the resistor contact is penetrated without contact and contacts the main contact on the fixed side. In the circuit breaker constructed in this way, although the movable contact is separated from the penetrating portion of the resistor contact, an arc will occur between the movable contact and the resistor contact. However, the re-arc arc and the previous design of this paper are applicable to the Chinese national standard (CNS) Α4 (2 丨 0 × 297 mm), —4 — A7 Printed by the Central Labor Bureau of the Ministry of Economic Affairs, Zhengong Consumer Cooperative, B7 Explanation of the Invention (2) The idea will also require consideration to avoid arcing between the ground and the re-arc arc while bridging the resistor body contact, because it will occur between the resistor body contact and the fixed side contact. The potential difference, so it is necessary to consider that arcing will not occur during this time. Although there is an opening for moving contact penetration in the central part of the resistor contact, when the arc starts from the movable contact and bridges the opening of the resistor contact The arc will easily flash through the opening. In the previous design ideas, it is ideal to bridge the center of the contact with an arc, but it cannot meet the above requirements. The purpose of the present invention is to provide a side that can ensure a movable connection. A circuit breaker that maintains the insulation performance between a resistor body contact and a fixed-side contact when the arc is restarted between the point and the electric body contact. [A device for solving the problem] is To achieve the above object, the circuit breaker of the present invention is mainly provided with a fixed-side contact, a movable contact that will come into contact with the fixed-side contact, and leave, and a resistor contact installed at the fixed-side contact. The circuit breaker having the resistor body contact and the gap that the movable contact does not contact is characterized in that the movable contact is formed in a cylindrical shape, and the central part and the outer peripheral part of the front end of the movable contact, It forms a shape where the electric field on the outer peripheral part is higher than that on the central part. At the same time, it mainly has a fixed-side contact, a movable contact that will come into contact with the fixed-side contact, leave it, and be mounted on the fixed-side contact. Resistor contact * A circuit breaker formed with a gap where the resistor contact and the movable contact will not contact, and is characterized by being located at a center 5 to 5 above the resistor contact.

Description of the invention (3) Opening to the outer periphery The side-separated position forms a part where the electric field is higher than that of the central opening.-[Function] In the circuit breaker according to the present invention, the bridging point of the arc will be changed from the movable contact to the contact of the resistor body when the circuit breaker is restarted. The position where the movable contact of the resistor contact will leave, so when the arc restarts from the movable contact to the resistor contact, it can prevent arcing from the opening of the resistor contact to the fixed-side contact. Embodiment] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG. 1 is a cross-sectional view showing the structure of a circuit breaker, and FIG. 2 is a diagram of a contact structure of a circuit breaker with a resistor. * It is a diagram schematically showing the contact structure with an impedance circuit breaker attached. FIG. 4 is a circuit diagram, and FIG. 5 is a diagram showing a bridge position of the re-arc arc. As shown in FIG. 1, this embodiment The circuit breaker is mainly composed of a movable contact 2 housed in a grounding tank 1, a fixed-side contact 4, a resistor contact 3 and a resistor 5 installed in the fixed-side contact. • The grounding tank 1 is filled with Used as S Fe gas for insulation gas. An operator is connected to the movable contact 2 to control the movement of the movable contact 2. The movable contact 2 is electrically connected to the conductor in the insulating spacer 21, and the fixed contact 4 is supported in the insulation. The conductors of the spacer 21 are electrically connected. The movable contact 2 | is an opening through the central part of the resistor 3, which is connected to the fixed side.

Fig. 3 schematically shows that this embodiment has a resistance disconnection. Resistor contact structure, but the fixed side contact 4 is provided with a resistor contact 3 via a resistor 5 > shows a state where a re-arc arc occurs between the movable contact 2 and the resistor contact 3 "by the circuit It can be seen from FIG. 4 that the circuit breaker of this embodiment is constituted by the switch 10 of the main circuit and the switch 1 of the resistor circuit. The process of moving the movable contact 2 through the penetrating part of the resistor contact 3 After passing, repeat the arcing between the resistor and the resistor as shown in Figure 3. As shown by circle 2, in this embodiment, the movable contact 2 is formed into a cylindrical shape, with the central portion being flat, and the outer periphery having a corner shape. The front end portion becomes stronger than the electric field at the central portion. Shape • At this time, the shape of the outer peripheral portion of the movable contact 2 may be a shape without forming a corner portion, as long as the shape of the electric field at the outer peripheral portion of the movable electrode 2 is stronger than that at the center portion * The shape of the part is the shape of the strong electric field. The equipotential distribution will be distributed along the corners as shown in Fig. 5, and then the arc 6 will progress in the direction perpendicular to the equipotential line 7, so it will be at the contact point of the resistor. The through part of 3 is bridged away. As a result, the re-arc arc with the resistance circuit breaker will not flash at the fixed side contact 4, and the reliability of the circuit breaker can be improved. Hereinafter, the second embodiment will be described based on 圔 6. In this embodiment, the resistor contact 3 is formed in a straight line, and a protrusion 8 is formed at a position of the resistor contact 3 away from the central opening 9 toward the outer peripheral side. The electric field becomes high at the protrusion 8 In this way, according to An opening (Please read the notes on the back of Susan Chan reloading the page)
