Device protection series motors ACC

ACC-01 with digital setting and display of monitored parameters is designed to protect three-phase induction motors h/220 V or h/380V (including submersible pumps) from the consequences: - overload; - asymmetry of the load; - work with underloading; - exceeding the supply voltage; - lowering the supply voltage; - incorrect phase sequence; - reduction of the insulation resistance of the windings of the motor before you start, and switching of electric circuits when the one of the controlled parameters specific, pre-programmed level. At the same time, in addition to the protective function, the relay has a number of important service functions: • monitoring of the following parameters: - input current for each phase (IA, IB, IC); - voltage on each phase (UA, UB, UC); - frequency network; counter service life; - as well as anomalies in the network and causes the onset of emergency conditions; • configurable number of automatic start-up after emergency stop (up to five with a time interval between re-starts 15); • protection configurable parameters from nasanktsionirovannogo access (password); • the ability to reset saved settings accident without switching the device off (handshaking). The memory settings are non-volatile and can store values during the whole period of operation that provides reliable protection and extends the maintenance period. Conditions: for execution U3, UHL2: -40...+55 °C; for the execution of T3: -10...+55 °C. Device ACC-02, ACC-03, ACC-04, ACC-05, ACC-06 is designed for comprehensive protection of three-phase asynchronous motors 3 (220/380) (including the management of deep-well pumps) with indication of the causes of accidents and transmission of information on control points and automatic re-start. The lineup can be used to control manufacturing processes, and objects of pumping stations and transmission complete information on control points. The device provides light signaling: • incorrect phase sequence of the supply voltage; • overcurrent motor; • current cutoff for the locked rotor; • exceeded the maximum level of the supply voltage; • lowering the minimum level of the supply voltage; • exceeded the maximum level on motor current; • lowering the minimum level of current of the motor; • exceeding the maximum temperature of the engine; • violations of the acceptable insulation resistance of the motor; • sticking of the contacts of the starter; • exceeding the permissible level of asymmetry of the currents of the engine; The purpose of the device: • ACC-02 simple overcurrent relays with a minimum set of security features • ACC-03 universal protection of industrial engines with the required set of security features • ACC-04 universal protection of industrial engines with RS485 interface with the advanced set of service functions and security features • ACC-05 universal protection engines for deep-well pumps and pumping stations with the most necessary protection Suite • ACC-06 universal protection engines for deep-well pumps and pumping stations with the required set of security data transfer capability via RS485 and advanced set of security features and service.
