Maximum current release RTV-2 (relay RTV)
Maximum current release with limited dependent exposure time (relay UNITS) is used for the drive of the PPO-10, pp-67, pp 67 k. Relay UNITS used to step current setting drive high-voltage switch. Used in diagrams, 11220 11222, 11224, 11226, 22000, 22200, 22240, 22400.
Manufactured in 6-minute versions: RTV-I from 5a to 10A; RTV-II from 10A to 20A; RTV-III from 20A up to 35; RTV-VI from 5a to 10A; RTV-V from 10A to 20A; RTV-IV from 20A up to 35 a. Error relay UNITS relative to the current response scale in cases +/ -10%. Error current tripping on one setting 4%
Relays have limited exposure characteristic subordinate UNITS of time. Shutter response time adjustable from 0 to smoothly 4 sec in not dependent of its features from current and timing error is no more than 0.2 sec.
Time relay UNITS are available in two versions:
and transition to independent) part time delay characteristics of current in the coil circuit 120-170% current setpoint options RTV (I); RTV-II; RTV-III;
b) with the transition to an independent part features excerpts of time current in coil chain 250-350% current setpoints WA proposing RTV-IV; RTV-V; RTV-VI.
Modification of relays are different stiffness of the spring. Minimum rate of return relay-0.61. While working in PTB relay is not dependent on the current part, features excerpts of time repayment rate is increasing and equals to: for the relay UNITS-I (RTV-1); RTV-II (RTV-2); RTV-III (RTV-3)-0.75 -0.80; for the relay UNITS-IV (RTV-4); RTV-V (RTV-5); RTV-VI (RTV-6)-0.95 -0.98.
