    Abstract: A REMOTE CONTROL CIRCUIT BREAKER SYSTEM IN WHICH AN ELECTRONIC LOGIC UNIT IS BUILT INTO A MAIN ELECTROMAGNETICALLY OPERATED CIRCUIT BREAKER TO ACT AS THE CONTROLLING INTERFACE BETWEEN THE LATTER AND REMOTELY LOCATED PILOT CONTROL-CIRCUIT BREAKER UNIT. IN ADDITION TO DIRECTING MAIN CIRCUIT BREAKER OPERATION TO PROVIDE CLOSING AND OPENING OF THE SAME IN CORRESPONDENCE WITH THE OPERATION OF THE PILOT UNIT, THE LOGIC UNIT RESPONDS ON OVERLOAD TRIP OPEN OF THE MAIN CIRCUIT BREAKER TO SUBJECT THE PILOT UNIT TO A CONTROLLED VALUE OF SIMULATED OVERLOAD CURRENT AS WILL CAUSE THE LATTER TO TRIP OPEN AND AFFORD INDICATION OF THE OCCURENCE OF OVERLOAD TRIPPING IN THE MAIN CIRCUIT BREAKER. THE LOGIC UNIT ALSO AFFORDS COORDINATION OF A PLURALITY OF SUCH CIRCUIT BREAKERS IN A MULTIPHASE A.C SYSTEM SO THAT ALL WILL BE RESPONSIVE TO THE OPERATION OF A SINGLE REMOTE PILOT UNIT, AND WILL ALSO TRIP OPEN FOLLOWING OVERLOAD RESPONSE OF ANY THEREOF. FURTHER THE LOGIC UNIT AUTOMATICALLY FUNCTIONS IN THE EVENT OF A FAULT OCCURRING IN THE PILOT UNIT OR THE LINE CONNECTING IT WITH THE MAIN BREAKER TO LIMIT THE VALUE OF FAULT TO A NON-DESTRUCTIVE VALUE, AND PREVENT REPEATED CIRCUIT BREAKER CYCLING IN THE EVENT THE PILOT BREAKER FAILS TO OPEN. THE MAIN CIRCUIT BREAKER USES DOUBLE-BREAK CONTACTS AND PERMANENT MAGNET LATCHING TO IMPROVE ITS ARC RUPTURE WITHSTABILITY AND ELIMINATE THE NECESSITY OF CONTINUOUS ENERGIZATION OF ITS ELECTROMAGNETIC OPERATING COILS. THE OVERLOAD TRIP MECHANISM IN THE MAIN CIRCUIT BREAKER USES A LOW FRICTION LATCH, AND TOGETHER WITH AMBIENT TEMPERATURE COMPENSATION IN THE BIMETAL LATCH RELEASE ENCHANCES THE TRIP POINT PRECISION.

    Abstract: A mounting clamp including heat sinks for a compression mounted type power semiconductor device such as an SCR, rectifier diode, or the like. Diamond shaped, tapered springs distribute the stresses equally throughout their lengths to afford greater deflection that reduces tolerances and facilitates staying within the allowable pressure range. A unitary spring subassembly also holds the pressure bearing and the load indicator. The construction is such that if the various parts become tilted on the pressure points, the line of force will still be through the center of the silicon disc inside the SCR. A pressure plate provides an enlarged base to afford low unit pressure on the insulation. Insulated parts afford the required electrical clearances. A dust-tight insulating cover or ''''boot'''' performs sealing, positioning and insulating functions during use and may also serve as a cushioned packing during shipment.

    Abstract translation: 一种安装夹具，包括用于诸如SCR，整流二极管等的压缩安装型功率半导体器件的散热器。 钻石形的锥形弹簧在其长度上均匀分布应力，以提供更大的偏转，从而减小公差，并有助于保持在允许的压力范围内。 一体式弹簧组件也可以保持压力轴承和负载指示器。 这种结构使得如果各个部件在压力点上变得倾斜，则力线仍将通过SCR内的硅盘的中心。 压板提供了一个扩大的基座，以在绝缘层上提供低的单位压力。 绝缘部件提供所需的电气间隙。 防尘绝缘盖或“靴子”在使用过程中执行密封，定位和绝缘功能，并且还可用作装运时的缓冲包装。
