9 EST and EDT disconnectors are classified as maintenance-free components, with the number of cycles before maintenance - 10,000 cycles (or 10 years). Disconnectors have noiseless economic electric drive, capacity 18 W. pplication of electric drives controlled with automation system reduces risk of disconnectors and support insulation damage in case of false staff operation with undue exertion. Disconnector EST, EDT disconnectors manufactured by Elpro (Germany) are applied for electric power circuit switching. Disconnectors have a unique crimptype contact system design with double gap and wiping contacts, geared by a small-sized servo drive. Ease of trolley with double-pole EDT disconnector withdrawal is achieved by original design of the disconnector. Each pole has two rows of fingers that in original (opened) condition are set so that the connected s enter the gap between fingers easily without mechanical resistance. Further, servo drive brings the fingers together to, crimping the with great force. Line Tester (Short Circuits Tester SCT) Short circuit tester SCT allows to determine line resistance before high speed circuit breaker closing. If line resistance is lower then setting parameter, SCT prohibits closing of high speed circuit breaker. Cable Control System Cable control system provides monitoring of cable internal and external insulation resistance, as well as signaling in case of insulation degradation. Cable control unit is supplied by circuit voltage, therefore is at potential to operating. Galvanic isolation is made of optic wire conductor. The unit has three contacts pairs - two per each signal: voltage availability; external insulation resistance reduction lower the setting; internal insulation resistance reduction lower the setting. Voltage galvanic isolation is done by application of relay with insulation voltage minimum 5 kv. The casing is made of fire-resistant insulating material.
