Bridge cable R334 (R 334, R-334)
Bridge cable R334 is designed to measure the resistance at DC scheme single bridge, to determine where the damage to the cable DC, to measure the asymmetry of the wire, and for insulation resistance measurement, to determine the location of the break in the cable capacitance measurement for measuring the capacitance of power transformer windings and cables.
Bridge cable R334 are designed to operate at an ambient temperature of 15 to 35 ° C and a relative humidity of 80%. The normal temperature of 20 ± 5 ° C.
In terms of resistance to mechanical stress, the device belongs to the ordinary.
The measured values, measurement limits and permissible error given in the table.
Bridge voltage is carried out by means of eight dry cell type "Mars."
Overall dimensions of the bridge 400h275h155 mm, weight 8.5 kg bridge.
All nodes in the circuit device mounted on a horizontal metal plate, placed in a metal housing with a removable cover. Under the hood is a panel of the measuring circuit. On the inside cover of the bridge plate is attached to the scheme.
Most cable R334 has an internal battery, which consists of eight dry cell type "Mars", which are set in the drawer (in the bottom of the hull).
