The conventional arc extinguishing device equipped with a magnetic plate 51 attracts the arc 52 to the notch groove 50 by the induced magnetic field of the notch groove 50 generated by the arc 52, and the arc 52 is drawn to the magnetic plate 51.
The arc 52 is cooled by heat conduction through contact with the magnetic plates 51, and the arc voltage is increased by dividing the arc by the magnetic plate 51. In the case of arc splitting, when the arc 52 is split by the magnetic plate 51, for example, in the case of an iron plate, a cathode point voltage of about 25V is generated, thereby increasing the arc voltage. Note that 53 is a contact portion, and an arc 52 is generated between contacts 54 and 55 of the contact portion 53 due to a short circuit or the like.
しかしながら、この消弧装置は、高いアーク電圧を得る

The drawback is that it can cause short circuits between conductors or other conductors.

少なくすることができる。According to the configuration of the present invention, the arc is attracted to the notched groove and approaches the insulator covering the magnetic material, thereby heating the insulator and generating pyrolysis gas from the insulator. This pyrolysis gas cools and extinguishes the arc. Also, when the arc comes into contact with the insulator, the heat of the arc is radiated and cooled. Therefore, a high arc voltage can be obtained without increasing the hexagonal mantissa, and damage to the MI magnetic plate can be reduced.

The contact portion 6 has a fixed contact 8 having a fixed contact 7 and a movable contact 10 having a movable contact 9, and the movable contact 10 opens and closes with respect to the fixed contact 8. Further, when the movable contact 10 is instantaneously opened when a short circuit accident occurs, an arc 1 is generated between the movable contact 9 and the fixed contact 7.

。Moreover, FIG. 4 shows the arc voltage when a short 4-fire test was conducted using various insulating materials. Note that the short circuit test was performed by discharging the capacitor. That is, both ends of the charged capacitor were short-circuited with a circuit breaker via a limiter/1tlffl resistor, and the arc voltage between the contacts at the time of disconnection was measured. In this case, the peak value of the short circuit S current is IKA, and the contact material is Ag-
In the diagram with W (W40Z) and a contact opening speed of 3 m/sec, Ql is polymethylpentene, Q2 is polymethyl methacrylate, Q3 is polybutylene terephthalate, and Q4 is ceramic. From this figure, it can be seen that the arc voltage of Ql and Q is high and the breaking performance is excellent.

めである。Furthermore, when the insulating material is filled with 5 to 35% by weight of glass fiber, a reinforcing effect can be obtained that prevents the insulator from cracking due to thermal deterioration due to thermal heat cycles caused by opening and closing of the contact portions. . In addition, the glass fiber is
The reason for limiting the amount to 35% by weight is that if it is less than 5% by weight, the reinforcing effect of the glass fiber will be lost, and if it is more than 35% by weight, the effect of thermal decomposition of the insulator will be reduced and the moldability of the glass fiber will be poor. This is because the damage to the mold becomes severe.
