CT19A/CT19B TYPE Spring Operating Mechanism
Our produces CT19 have two kinds, match with a fixed counter (CT19B) and match with handcarts (CT19A).
CT19-series spring operating mechanism use for actuator all kinds of type ZN28 breaking current 20KA, 31.5KA, 40KA indoor high voltage vacuum circuit breaker or other vacuum circuit breakers type that equivalent Operating closing function.
Our produces CT19 have two kinds, match with a fixed counter (CT19B) and match with handcarts (CT19A). CT19B model is based on the type CT19A small improvement after that more stable and reliable mechanical properties.
The actuator storage methods are two kinds of manual storage and electric energy storage, opening operation have four kinds of brake solenoid, over-current tripping device solenoid and manual button operation and undervoltage tripping device solenoid.
Mainly Technical parameters
Mainly Technical parameters 1. Technical data for storage energy motor with permanent magnet motor :| Type | 66ZY-CJ01 | 66ZY-CJ11 |
| Rated working voltage(V) | 110 | 220 |
| Motor rated input power (W) | 70-150 | |
| Normal working voltage range | 85%-110% rated working voltage | |
| Rated working voltage for storage energy times | ≤12s | |
If consumer requested adopt AC power storage energy, should enhance full wave rectifier power supply storage energy motor for working . 2. When adopt 400mm length storage energy operating handle for manual storage energy, it’s operate force at least 140N 3. Closing magnet adopt screw type magnet , technical data as follow sheet ,
| Rated working voltage(V) | ~110 | ~220 | ~380 | -48 | -110 | -220 |
| Rated working current (A) | 5 | 3 | 3.78 | 2.3 | 1.77 | |
| Rated power (W) | 550 | 660 | 181.4 | 253 | 390 | |
| Coil resistance value on 20°C(Ω) | 7.2±1 | 20.7±2.05 | 12.7±2.5 | 47±2.5 | 124±5 | |
| Opening working voltage range | 65%-120% rated working voltage to be reliable for opening | |||||
| when less than 30% rated working voltage, continuous 3 times shouldn’t be open | ||||||
| Closing working voltage range | 85%-110% rated working voltage | |||||
4. Opening magnet with independence power supply and over-current tripping magnet, which adopt screw magnet. a. Overcurrent tripping electromagnet powered by a current transformer, the circuit closing action depend on the dividing device over-current relay contact, action value setting by the current relay, over current relay solenoid rated current 5A, pure resistance 2.6 ± 0.5 (Ω) b. By an independent sub-gate solenoid power supply technical data see table above, consistent with the closing solenoid parameters. c. Tripper combination and code:
| Tripper combined code | Tripper name and code | |
| Over-current tripper magnet (piece) | Opening magnet (piece) | |
| 100 | 1 | 0 |
| 110 | 2 | 0 |
| 111 | 3 | 0 |
| 104 | 1 | 1 |
| 114 | 2 | 1 |
| 400 | 0 | 1 |
