IPC: H01H73/00
Filed: 1995-03-24
Abstract: PURPOSE: To easily judge deterioration without interrupting use of a circuit breaker by providing a portion which, when a switch contact part is in the normal condition and the current carried varies, has an substantially constant temperature difference with respect to the switch contact part or a nearby portion. CONSTITUTION: Thermocouples 16, 17, having respective temperature sensing parts anchored thereto, are provided, respectively, on the portions of the back face of a case 1 near a switch contact part and near the portion of contact between a heater 7 and an interrupting terminal 8. The anchored positions of the temperature sensing parts of the thermocouples 16, 17 are set in portions which, when the circuit breaker is in the normal condition, have an almost equal temperature difference even if current values are different.  This temperature difference is calculated beforehand and compared with the difference in the outputs of the thermocouples 16, 17 under service conditions, whereby judgment on deterioration can be made; i.e., the tendency of the switch contact of the circuit breaker in use to deteriorate can be detected readily without interruption of currents or use of a current measuring device, such as an ammeter, so circuit reliability can be secured easily without any influences on the supply of power.

Abstract: PURPOSE:To detect the currents of each phase and the polarity of revolving torque by detecting the currents of two phase in three phase by one current detector, preparing currents flowing through each phase while being synchronized with timing driving an inverter switching element on the basis of the detecting signal of a two phase section and feeding back the currents. CONSTITUTION:A current detector 41 generates the current detecting voltage of a two phase section by currents flowing in U and V phase. A detecting- current forming appliance 43 amplifies the current detecting voltage by weighting corresponding to the timing of the voltage, and inputs a feedback signal to a current waveform arithmetic circuit (IC) 44. The IC 44 waveform- operates torque from a speed operational aplifier 17 and a current command signal, by which the speed of rotation reaches a set value arithmetically, and a current control signal, by which the deviation must be controlled in zero, is input to a drive circuit section (DC) 45. The DC 45 converts the deviation into a PWM signal, and turns a switching element making currents flow through U phase from V phase in a switching circuit section 2 ON-OFF together with the timing signal of a timing generating circuit 42.

The base electrode 114 comprises doped polysilicon and is separated from a collector electrode 102 by an insulator layer 110. A conducting spacer 115 acts as the dopant, source for the base linking region 112 and is used for connecting the region 112 to the base electrode 114. Thus the highly reliable, simple manufacturing of the self-aligning base linking region 112 can be performed, and almost entire impurity capacity can be eliminated.
