Structural features M1101
Megger M1101 consists of a generator with a drive mechanism and a ratiometric device.
Generator megger M1101 is a constant current source and consists of a magnetic stator poles and the rotor plate, which is a permanent magnet; eight. The rotor and the stator is driven in rotation gear connected to the handle.
M1101 ratiometric device consists of a fixed part (permanent magnet, magnetic, pole pieces) and mobile (working and opposing frame). Operating and opposing frames are rigidly attached at an angle of 90 °.
The principle of operation M1101
When a complete revolution of the rotor rotating direction of the unit M1101 magnetic flux crossing the stator winding is reversed eight times. Thus due to the polarity of the rotor magnet is induced in the stator windings an alternating voltage is rectified by the collector 4.
The constancy of the terminal voltage is maintained M1101 centrifugal governor of the load. With increased speed unit handles loads due to centrifugal forces apart and pushing the rotor from the stator, reduce the magnetic coupling induced in the coil and its voltage.
Currents flowing through both coils and interacting with a magnetic field, create torques in opposite directions. Angle movable part depends on the relationship of currents in the coils and does not depend on the applied voltage.
When measuring the resistance of the circuit megger M1101 attached to the terminals of the device, its movable part is rotated by a certain angle, and fixed to the axis of the arrow indicates the amount of resistance on the scale of the instrument is calibrated in kilohms and megohms.
The device operates in this mode - intermittent measurement - 1 minute pause - 2 minutes. The speed of rotation of the handle unit M1101 - 120ob/min - 144ob/min. Response time - no more than 4s.
Megaommetry M1101 uses power from the built-in mechanical oscillator.
The product is designed for use in the following conditions:
- Ambient temperature - from -30 ᵒ C to +40 ᵒ C;
- Relative humidity - up to 90% at +30 ° C.
The manufacturer guarantees that the product complies with the specifications under normal use, storage, transportation and installation. Megger M1101 meets the requirements for ensuring safety of life, health, consumer and environmental protection.
