6. 3 1 2 Circuit breaker The mechanical closing time of the circuit breaker is defined as the time between the electrical command to the operating coil and touching of the main contacts On the other hand the opening time is the time between the electrical command and the separation of the main contacts The operating times of circuit breakers independent of the breaking system and the type of operating mechanism changes in dependence on certain service parameters e With reduced control voltage at the operating coil there is less energy available to change the electrical control commands into a mechanical action The operating time extends itself Valid for all types of operating drives e By altering the hydraulic pressure on hydraulic drives the energy available to carry out the switching movement changes e The ambient temperature is the most complex parameter of influence The electrical resistance of the operating coils the oil viscosity and the pressure of the SF6 gas are all dependent on the temperature Moreover there is expansion of operating rods and porcelains All these parameters influence the operating time in different Ways In the extreme each of these 3 parameters can alter the operating time by some milliseconds The RPH2 is in the position to compensate these operating time variations 3 1 3 RPH2 structure The outstanding features of the RPH2 are e Microprocessor control with a switching command time resolutio
