ZXMN-C Simulator Circuit Breaker Device
The ZXMN-C circuit breaker simulation device is mainly used for the whole set of test of the relay protection device. The device can simulate the tripping / closing of the circuit breaker during the entire group of tests of the relay protection device, which can reduce the number of switching actions, extend the service life of the circuit breaker, shorten the debugging time, improve the test work efficiency, and avoid the circuit breaker during the entire group of tests inconvenience caused by repeated switching.
The ZXMN-C analog circuit breaker device can cooperate with the relay protection tester produced by our company to perform non-stop power verification on the protection device and improve the reliability of power supply.
Manual
Video1. Has an independent dual loop trip coil; has a malfunction, reset function.
2. The panel embedded touch keyboard is used as a human-computer interaction device, and is equipped with a high-end LCD screen display, which can be used for intuitive and direct operation selection of experimental parameters.
3. With humanized voice prompt function, the system can emit a beep every time a normal operation is performed. If the operation is improper, the system will issue three beeps-beep-beep-beep.
4. Using a single-chip microcomputer as the control core. The weak current control loop is composed of integrated circuits, photoelectric coupling and solid-state components, with stable performance and precise time control.
5. The MCU input circuit has reliable isolation measures from the strong electricity part, and can withstand 1.5KV AC and DC voltage. The instrument is completely disconnected from the external input circuit when it is not turned on, which eliminates the hidden danger of the operator burning the instrument for a long time without testing, safe and reliable.
1. Input voltage: AC220±10% 50Hz working current is less than 0.5A
2. Tripping method: split phase, three phase
3. Tripping and closing operation voltage: DC110V or DC220V.
4. Tripping current selection: 0A, 0.25A, 0.5A, 1A, 2A, 4A, 5A
5. Trip time selection: 20ms, 40ms, 60ms, 80ms, 100ms, 110ms, 200ms error does not exceed +/- 3ms
6. Closing time selection: 50ms, 100ms, 150ms, 200ms, 300ms, 400ms, 500ms error does not exceed +/- 3ms
7. Simulated open circuit normally open / normally closed contact: AC220V/5A
8. Outer packing box size: 436 × 416 × 252mm
9. Instrument size: 400 × 380 × 205mm
