Control stations
The control station CS-PH/5/A is designed for remote control, asynchronous electromotor protection against overcurrent” and short circuit”, with a short-circuited rotor” (from 1 to5 pcs.) and outgoing connections” in mine three-phase electrical networks” with the insulated transformer neutral”.The type of climatic version is Ó5 according to State standard 15150-69, State Standard 15543.1-89”.
The station provides:
- protection against short-circuit currents of outgoing power circuits” and circuits supplied by the integrated transformer”;
- protection against outgoing power circuit overcurrent;
- protection against inadmissible thermal overload of pluggable equipment”;
- protection against opening” and short circuit” in remote control circuits”;
- protection against automatic switching in case of supply voltage rise up to 150% from the rated voltage”;
- protection against ground circuit opening or resistance rise of outgoing circuits exceeding permissible level;
- the locking device preventing tap switching in case of outgoing circuits fault condition and phase-to-ground insulation drop below the permissible level;
- protection against current leak in power circuits (input and output), circuits supplied by “127 V secondary side of the integrated transformer” and in 220 V internal supply circuits”;· remote control of every power circuit;
- alarm system for normal and emergency state protection and locking devices;
- zero protection.
