Description
круговом огне указанное сонротивленне снижаетс до единиц Ом н менее.All-round fire specified is reduced to units of Om n less.
Такнм образом, осуществл контроль нроводимости ионизированного воздуха в области кругового огн с номощыо двух зондов или замер разность нотенциалов между одной из щеток машины и зондом, размещенным в ионизированной области, можно судить о наличии или отсутствии кругового огн на коллекторе электрической машины.Thus, by monitoring the conductivity of ionized air in the area of circular fire with a number of two probes, or measuring the difference of notsiali between one of the machine brushes and the probe located in the ionized region, it is possible to judge the presence or absence of circular fire on the collector of the electric machine.
Реализаци устройства по предлагаемому способу заключаетс , как указывалось выше , в том, что в зоне распространени кругового огн устанавливаетс зонд, который соедин етс с логической частью защиты или непосредственно с се выходным органом , другой зажим которого подключаетс к одной из щеток машины. Логическа часть защиты ирн необходимости может содержать элемент выдержки времени. Выход защиты может быть подключен на отключающий аннарат, на сигналнзацию или подавать сигнал в схему автоматики системы.The implementation of the device according to the inventive method consists, as mentioned above, in that a probe is installed in the zone of propagation of the circular fire, which is connected to the logical part of the protection or directly to the output device, the other clip of which is connected to one of the machine brushes. The logical part of the iRn protection of necessity may contain a time delay element. The protection output can be connected to the disconnecting annarate, to signalization, or to give a signal to the automation circuit of the system.
Построение защиты по предлагаемому способу позволит осуществить более эффективную защиту электрических машин от кругового огн на коллекторе, сохранить дорогосто щие коллекторные машины и уменьшить врем просто технологического Constructing the protection according to the proposed method will make it possible to more effectively protect electrical machines from a circular fire at the collector, save expensive collector machines and reduce the time of just technological
оборудовани , св занное с заменой или ремонтом этих машин.equipment related to the replacement or repair of these machines.
