1.4 Construction and operation of the product

& nbsp;

1.4.1 Schematic diagram of the divider shown in Fig.1

divider circuit is formed by an ohmic voltage divider, and belongs. from block high A1 and measuring cable with built therein switchable load A2.

high-block consists of 16 resistors R1-R16 PE-10kV-68M, connected in series in a high shoulder and a resistor R17 (1M) in the low voltage leg. The input impedance is equal to the high-voltage unit 1088 & plusmn; 100 MOhm dividing ratio -1000 & plusmn;. 100 (at the disconnected cable measurement)

DN.10.80.00 measuring cable is made on the basis of the radio-frequency coaxial cable RG58-C / U. A built into it comprises load resistors switchable tumbler S1 & quot; VOLTAGE & quot ;. The presence trimmers R20, R21 allows you to adjust the division factor separately on DC and AC voltage. Adjustment is made by rotating the axes trimmers through openings in the side wall of the load body

2 Notes security

2.1 to work with a divider allowed persons with group safety in installations with a voltage above 1000 V is not lower than the third.

2.2 The case of the high-block divider must be grounded, and the operator station must be equipped with an insulating base & ndash; rubber mat with a dielectric, a group of I GOST 4997-75.

Other safety measures regulated by the Rules for Electrical / Energy devices SSSR., 6th ed., rev. and Sub-M .: Energoatomisdat, 1985.-640c.
