PURPOSE:To get rid of the sudden stop of an inverter due to cotton dust and prevent the thread of a spinning machine from being cut off by arranging two sets of the temperature switches of different working points. CONSTITUTION:A temperature switch 10 and an indicator lamp 11 are arranged, and a temperature switch 9 is set to be for protecting the operation stop of an inverter device, and by the closed circuit of the temperature switch 10 having a working setting temperature selected to be a value lower properly than the working setting temperature of the switch 9, the indicator lamp 11 is lit and a temperature rise is alarmed. Accordingly, when at the temperature selected to be the properly low value, compared with a set temperature for stopping the operation of the inverter device, the temperature rise of a cooling fin is alarmed, and cotton dust is properly avoided, then the inverter device, namely, a spinning machine, can be prevented of course from being suddenly stopped along with the excessive temperature of the cooling fin, and both ones can be continuously operated. |
