摘要： A semiconductor package that can suppress the rupture of the exterior even when the short-circuit failure occurs in a part of the semiconductor chips therein is provided. The semiconductor package includes a cooler (3) which is made of metal and which fixes a submodule (1), an outer circumferential side wall (4) which is made of resin and which is fixed to the cooler (3), and an upper plate which is made of metal and which is fixed to the outer circumferential side wall (4). The cooler (3) and the outer circumferential side wall (4) is fastened by a fastening member (6a), and the upper plate and the outer circumferential side wall (4) is fastened by a fastening member (6b). If the pressure in the submodule rapidly rises, the entire upper plate (5) is largely bent and deforms to prevent the destruction of the semiconductor package by the internal pressure rise.

摘要： According to the embodiments, a direct-current interrupting device includes a mechanical breaker (2), a semiconductor breaker (3), and a commutation device (4). The mechanical breaker (2) comprises a mechanical contact (6) made by connecting a high-voltage contact and a current interrupting contact in series, and bushings (8) which are connected to a pressure vessel (5) equipotential to the ground potential and electrically connect the both ends of the mechanical contact (6) and a direct-current transmission system. The commutation device (4) is connected to at least the high-voltage contact of a high-voltage contact and a current interrupting contact in parallel, and is connected to the semiconductor breaker (3) in series. The direct-current interrupting device opens the path of the mechanical contact (6) when an accident occurs in the direct-current transmission system to make a semiconductor stack (31) in a current-carrying state, and make the current flowing through the mechanical breaker (2) temporarily zero by the commutation device (4), thereby transferring the accident current from the mechanical breaker (2) to the semiconductor breaker (3). The direct-current interrupting device sets the semiconductor stack (31) to a blocking state after the transference, thereby blocking the accident current.
摘要翻译：根据实施例，直流中断装置包括机械断路器（2），半导体断路器（3）和换向装置（4）。机械断路器（2）包括通过串联连接高压触点和电流中断触点而制成的机械触点（6），以及连接到与地电位等电位的压力容器（5）的衬套（8），以及电连接机械触点（6）的两端和直流传输系统。换向装置（4）至少并联连接高压接点和断流接点的高压接点，并与半导体断路器（3）串联连接。当在直流传输系统中发生事故时，直流中断装置打开机械触点（6）的路径以使半导体堆（31）处于载流状态，并使电流流过机械装置（2）通过换向装置（4）暂时归零，从而将机械断路器（2）的事故电流传递给半导体断路器（3）。直流中断装置在传输之后将半导体堆叠（31）设置为阻塞状态，从而阻止事故电流。
