摘要： PURPOSE: A large power spiral switch is provided to obtain uniform discharge current flowing on electrode surfaces by preventing a localized discharge so that arc current density is under the threshold damage value of an electrode material. CONSTITUTION: A large power spiral switch comprises insulating housings(7,8), first electrode(1), second electrode(5), an insulator(10) and a wire coil(A). The insulating housings(7,8) are extended in the axial direction with internal spaces and have a discharge area(B). The first electrode(1) moves in the axial direction within the internal space of the housings(7,8). The second electrode(5) starts discharge in the discharge area while being adjacent the first electrode(1) according to the movement of the first electrode(1) to generate an arc. The insulator(10) is placed between the first and second electrodes(1,5) except for the discharge area. The wire coil(A) generates an axial magnetic field in the discharge area of the housings(7,8). The arc moves in the axial direction of the housings(7,8) along a spiral trajectory due to the magnetic fields from the arc and the wire coil.
摘要翻译：目的：提供大功率螺旋开关，通过防止局部放电，使电弧电流密度低于电极材料的阈值损伤值，以获得在电极表面上流动的均匀放电电流。构成：大功率螺旋开关包括绝缘壳体（7,8），第一电极（1），第二电极（5），绝缘体（10）和线圈（A）。绝缘壳体（7,8）在轴向方向上具有内部空间并且具有排放区域（B）。第一电极（1）在壳体（7,8）的内部空间内沿轴向移动。第二电极（5）根据第一电极（1）的移动而在与第一电极（1）相邻的同时在放电区域开始放电，以产生电弧。除了放电区域之外，绝缘体（10）被放置在第一和第二电极（1,5）之间。线圈（A）在壳体（7,8）的排出区域中产生轴向磁场。由于来自电弧和线圈的磁场，电弧沿着螺旋轨迹在壳体（7,8）的轴向上移动。

摘要： PURPOSE: A pulse power system is provided to minimize local damage of an electrode by moving arc generated between two electrodes by using Lorentz force. CONSTITUTION: When an electromagnet is applied with electric power, a magnetic substance is forced into the center of the electromagnet(85) to move an insulating rod(84) downwardly. Then, the insulating rod(84) is moved in the downward direction withstanding elastic force of a spring(88), and at the same time first electrode(81) is moved downward to be placed adjacent to the second electrode(82), thereby starting discharge between the first and second electrodes. When arc is generated between the electrodes, magnetic field is formed in theta direction and arc is moved in x direction by Lorentz force, thereby preventing local damage of the electrodes.
摘要翻译：目的：提供脉冲功率系统，通过使用洛伦兹力，通过在两个电极之间产生的电弧来最小化电极的局部损伤。构成：当电磁铁被施加电力时，磁性物质被迫进入电磁体（85）的中心以向下移动绝缘杆（84）。然后，绝缘杆（84）通过弹簧（88）的弹力沿向下方向移动，同时第一电极（81）向下移动以邻近第二电极（82）放置，从而在第一和第二电极之间开始放电。当在电极之间产生电弧时，在θ方向上形成磁场，并且通过洛伦兹力在x方向上移动电弧，从而防止电极的局部损坏。

摘要： PURPOSE: A large power pulse switch is provided to have an electrification power of 103MW and a discharge time of 5ms by preventing local discharge. CONSTITUTION: An anode(4) is provided on a hollow tube, and a cathode(6) is arranged on the center axis(C) of the hollow tube to be extended in the axial direction. The insulator(3) supports the anode(4) and the cathode(6) while insulating the same. A solenoid coil(2) is wound around the outer periphery of the anode(4). A spark plug(1) is extended toward the central axis(C) while being detached from the anode(4) in a predetermined position of the anode(4) on the hollow tube. Electrons emitted from the cathode(6) is moved along the length while rotating around the cathode on the axis(C) from Lorentz force by magnetic field to prevent local discharge.
