Title: Disconnection detector of field winding of synchronous machine
Inventor: KUDO YOSHINORI
IPC: H02K11/00
Filed: 1988-09-19
Abstract: PURPOSE:To prevent the damage of the rotor of a synchronous machine by also detecting a semi-disconnection state by providing a comparing means operated when the change quantity signal of a field winding resistance generated in the change quan tity detection means of the field winding resistance becomes predetermined relation. CONSTITUTION:In this disconnection detector, when there is no disconnection state, the resistance equivalent signal Rf calculated by a field winding resistance calculation means 7 is unchangeable to become actual field winding resistance but, when a semi- disconnection state is generated, field voltage rises by arc voltage and a field current is hardly changed and, therefore, the resistance equivalent signal Rf is calculated so as to be higher than actual field winding resistance. At this time, a change quantity equivalent signal DELTARf is calculated. That is, since the disconnection state of a field winding is converted to field winding resistance and the change quantity (increment) of the field winding resistance to the initial value is detected, the resistance value of heavy load operation is not detected and only the resistance value of the field winding due to an abnormal state can be detected and a semi-disconnection state low in arc voltage can be also detected.

Abstract: PURPOSE:To remarkably improve the error permissible value of a basic clock frequency at sender and receiver sides by making each pulse width of '1', '0' information of a start bit and a data bit different from each other with respect to a basic clock. CONSTITUTION:The sender side consists of an input section 3 and a transmission side 1, and the reception side consists of a load 4 and a reception section 2, and the transmission section 1 and the reception section 2 are coupled by a transmission line 5. A parallel data from the input section 3 is inputted to a parallel/serial conversion circuit 25 and converted into a serial data. In this case, '1', '0' data of the data bit 8 succeeding to the synchronizing bit 7 are modulated so as to have a different pulse width. The serial data is demodulated by detecting the '1', '0' information of the data bit 8 and the synchronizing bit 7 by using the detection pulse of a different time interval. Thus, the permissible range of the basic clock frequency at the transmission/reception side is expanded.
