DESIGNATION Fixation of the flow of short-circuit current one or several damaged sections of cable line to 10kV. · IKZ-02 - the indicator, built in the automatic systems. MERITS They are simple and convenient in the operation, nadezheny, they make it possible to rapidly determine the direction of the damaged sections on the branching off of cable line. TECHNICAL CHARACTERISTICS 1. Indicators are intended for the work at a temperature from minus of 25°S to plus of 40°S, relative humidity of air not more 98% with 20°S and to the height above sea level not more than 1000 m. 2. The nourishment of indicators is achieved from the network of alternating current with a voltage of (220+22,220-33) in and with the frequency (50±0,5) of Hz. 3. Power consumed from the network is not more than 6V·A. 4. Tuning range of the spill current 100-2000 of a. 5. The response time of indicators from the moment of the flow of short-circuit current is not more than 0,06s. 6. The resetting time of indicators into the initial state (with the presence of the feeding stress) is not more than 30 s. 7. Number of directions of the fixation of short-circuit current 3. 8. In the indicators the light-emitting diode indication of wear and tear is provided. 9. Time of retention by the indicators of information about the flow of short-circuit current on the section of the cable liniii (after its de-energizing at the moment of operation) not less than 8 hours. 10. Working signal the entrance of the block of indicator enters from the magnetic current-sensing device (MDT). Sensor is mounted in the cell, which go outs the cable line of the closed transformer substation at a distance 150 mm from the plane of tires asymmetricalally relative to the phases BUT, IN, (see figure) 11. With the presence of emergency disappears ~220V feeding stress. As a result light-emitting diodes on the front panel of the block of indicator go out, identifying emergency. With the pressure on any of the buttons, on the short period will be lit only the light-emitting diode, which identifies emergency in the appropriate cable line. If ~220V feeding stress is renewed, then indicator will automatically restore initial state not more than through 30 s. Recovery time is selected more than the time of operation of protection on the cable line so that IKZ would not have time to restore initial state in the emergency. Indicator IKZ-02 must ensure the transmission of the information in the form of discrete signal about its state (fact of wear and tear in the case of short on the controlled line) to the output circuit, interrogated from the discrete panel on the control cable systems. 12. Insulation resistance between the chains of net nourishment and the housing of indicators must be not less than 10 M. 13. Overall dimensions, mm, not are more: § the block indicator - of 216kh150kh65 § MDT - of 102kh60kh45 14. Mass, kg, not are more: § the block indicator - 2 § MDT - 0,2 DELIVERY SET Block is indicator 1 pcs Magnetic current-sensing device (MDT) 3 pcs Set of spare parts and equipment 1 kompl.
