Vintage USSR Soviet Russian Aviation force Portable Isolation control device PKI-2
We offer for delivery a device for continuous monitoring of insulation PKI-2
PKI2 device is designed for continuous automatic constant
monitoring of the insulation resistance of single-phase and three-phase alternating current electric circuits with voltage up to 400 V, frequency 50 or 400 Hz with an ungrounded neutral both in the presence of voltage in the monitored network and in its absence.
The device of constant control of isolation PKI-2 (pki2) is intended for constant control of electrical insulation with respect to the ground of all electrically connected elements of three-phase electrical installations with insulated neutral, under voltage (mobile sources of electrical energy, consumers of electrical energy fed from these sources of portable cable networks ) and to signal the reduction of insulation resistance to a critical value.
The PKI-2 device is used to work in networks powered by an alternator with a voltage of 230 or 400 V.
The PKI-2 device is designed to work in temperate climates (temperature from minus 40 to plus 50 degrees Celsius, relative humidity up to 98% at a temperature plus 25 degrees and height above sea level up to 1000 m).
Main technical characteristics of PKI-2 (PKI2) device:
The current of the controlled installation is variable, three-phase, with a frequency of 50 Hz.
The rated voltage of the generator controlled three-phase network in 230 or 400 V.
Power consumption: not more than 30 V * A.
The total resistance of a single-phase leak (the sum of the insulation resistance relative to the earth and the spreading resistance of the grounding conductor, taken not more than 700 Ohm), at which the device that controls the line voltage network operates:
230 V - from 10 to 16 kΩ;
400 V - from 17.5 to 22 kΩ.
The spread of resistance values ​​in different phases should not exceed 25% of the average value, and the average value should not exceed the limits indicated above.
The operation of the device is accompanied by a light signal.
The device works steadily with fluctuations in the voltage of the controlled network - from 0.9 to 1.05 of the nominal value.
Food - single-phase alternating current 127 V, frequency 50 or 400 Hz.
Lifetime - 25000 h
Weight 10 kg.
