Description of the invention (This invention relates to a kind of insulating dice that is installed in a dielectric filled with a high dielectric strength gas and includes a self-extinguishing expansion. A medium voltage circuit breaker of a cassette in the form of an arc extinguishing chamber, comprising-a fixed arc contact cooperating with a movable arc contact,-placed near the fixed arc contact to be used when the arc is switched to An electromagnetic coil that generates a magnetic field in the gap between the electrodes after an electrode, and an insulating sleeve made of insulating material that is fixed to one end of the cassette and equipped with an insulating sleeve for guiding a movable arc contact Support arm. When a short-circuit current is interrupted, the thermal behavior of the arc in the cassette may generate a huge gas due to the presence of the gas-generating plastic material of the support arm. A part of the gas that may hinder the self-extinguishing expansion effect may enter the cassette and cause the risk of re-flashing. The purpose of the present invention is to improve the disconnection performance of a self-extinguishing expansion circuit breaker.

The amount of this card is set at the bottom, and the thermal protection shell plate of the solidified part is installed on the bottom of the base. The pressure of the Paiyi loop is fixed by the fluorine to make a four-way routing, and the regulation and gas accumulation of electricity will lead to the promotion of Pai I. The reference to this part by the guide includes the bottom finger and the heat. By covering the base, the part covering means that the ring covering base of the arm covers the base of the sensing material, and the root branch of the sensing material and the hot glue on the plastic mounting part of the thermal shoulder are applicable.

Description of the invention (α). The presence of this plate prevents the generated gas flow from entering the cassette, which helps the arc to be extinguished. According to the characteristics of the invention, this The pick-up electrode of the arc is coplanar with the ring-shaped contact rail used to rotate the arc. The above rail is connected to the front of the coil. The other side of the line is connected to a current input pin by a magnetic circuit. In order to strengthen the magnetic field in the opening gap, the coil is excited by a ferromagnetic plate of a magnetic circuit. The above ferromagnetic plate is electrically connected to the conductive cassette. In order to resist the disconnection caused by the electric force, The end rotation of the coil is independently fixed to the magnetic circuit and the contact rail by the auxiliary rib screw. According to a preferred embodiment, the arc contact forms a flexible component, and when the movable arc contact is occupied in the fixed arc contact in the connection position, the spring leaf supports and fixes the arc contact and the conduit. The associated contact finger M provides the contact pressure. The arcing to the electrode is assisted by an adjustable direction including a support portion including a notched metal ring for adjusting the axial gap between the fixed arc contact and the electrode.
