Universal protection block induction motors operation-M
Operation-m 5-50A
Operation-m 10-100A
Operation-m 63-630A
Designed for continuous monitoring of the parameters of the mains voltage and RMS values of phase/line currents of three-phase equipment 380V, 50Hz, primarily asynchronous motors (ED) capacity from 2.5 kW to 315 kW, including in networks with isolated neutral.
Provides full and effective protection of the motor is disconnected from the network and/or blocking its start in the following cases:
asymmetrical the reloading phase/line currents associated with the damage inside engine - protection against distortions of phase currents and subsequent ban automatic reclosing (AR);
at unacceptably low levels of insulation on the body - check before turning on lock start with poor insulation;
- poor
network voltage (unacceptable voltage fluctuations, broken phases,
violation of rotation and adhesion phases, phase distortion/linear
stress);
mechanical overload (symmetric overload phase/line currents) - protection against overload with a dependent time delay;
- unbalance phase currents without reloading related to violation of insulation inside the motor and/or the power cable;
the disappearance of torque on a shaft ED ("dry run" for pumps) protection at the minimum starting and/or operating current;
- the grounding winding of the stator during operation - protection against leakage currents to ground.
Block protects the motor by controlling the coil of the magnetic starter (contactor).
Performs the following functions:
·
simple and accurate setting of the rated current ED using standard
scale nominal currents;
· installation of operating current ED, non-standard values taking into account the long-term permissible overload;
· tripped on overload with a dependent time delay. In the process work solved the differential equation of the heat balance ED;
· ability to move the current-time characteristic as axis currents and the time axis;
· setting trip thresholds for the minimum/maximum voltage imbalance line voltages and phase currents, and time AR at the discretion of the customer;
· indication of the type of accident, the presence of line voltage, current range, which is configured to block and the load;
·Possible delivery in Ukraine carriers. .
