The invention discloses a rotor short-circuit ring combined structure and a processing method thereof. The rotor short-circuit ring combined structure comprises a rotor core, two porous ring sheets, aplurality of conductive copper sheets, a wire ring, two proper circular rings and two short-circuit rings; the porous ring sheets are respectively connected in series with two ends of the rotor core;after the wire ring is connected with the conductive copper sheets one by one in a stringed manner, the conductive copper sheets are inserted into the rotor core and the porous ring sheets, the two ends of each conductive copper sheet protrude out of the axial cross section of the rotor core; the conductive copper sheets are arranged in a perfect circle through the cooperation with the constraintof the proper circular rings; and the short circuit rings are integrally formed at the two tail ends of the rotor core and the conductive copper sheets through a casting process. By means of the composition of the components, the short-circuit ring structure is integrally formed by combining the conductive copper sheets, so that troubles in the production of short-circuit rings in the prior art are eliminated.

The invention discloses a system for monitoring the working condition of a low-voltage station area and automatically adjusting the three-phase load balance, which includes a low-voltage multi-capacity capacitor, an automatic phase change switch, a residual current circuit breaker, a distribution network monitoring terminal, and a system platform. The network monitoring terminal is connected to the system platform through the GPRS network, and the residual current circuit breaker is installed on each power supply branch on the low-voltage side of the distribution network with the low-voltage multi-capacity capacitor connected in series. The residual current circuit breaker is connected through the 485 communication mode It is connected with the monitoring terminal, and the automatic reversing switch is connected with the monitoring terminal of the distribution network through the wireless power carrier, wherein the low-voltage multi-capacity capacitor includes a plurality of parallel-connected equal-capacity charging elements, and the parallel-connected lines of the equal-capacity charging elements The electric control switch is connected in series to realize the matching of capacitance compensation level. The invention can realize the automatic adjustment of the three-phase load balance and the matching of the reactive power compensation capacity level, reduce the electric energy loss in the station area, and reduce the frequency of the three-phase automatic adjustment and commutation in the peak period.
