CB Test Equipment Circuit Breaker Simulator
I. Overview
HZMN-D3 Circuit breaker simulator is designed for the relay protection switch analog simulation test. It is manufactured by the integrated circuit to realize the setting of the tripping time, the logic of the input signal and the power electronics with protection. The trip coil is independent. The dual-loop design simulates the behavior of three-phase and phase-separated operation, single-trip coil or double-trip coil circuit breakers with a voltage rating of 6-500KV. It is suitable for use in power systems, industrial and mining enterprises, research institutes, professional colleges, and protection manufacturers. It is an alternative device for actual circuit breakers in relay protection and automatic devices with switch system. The operation is accurate, reliable, and the number of actions is not Restricted, it can greatly improve the correctness and integrity of the test, minimize the number of actual circuit breakers, and improve the service life. It is an important supporting equipment for relay protection test work.
II. the main performance indicators
1. Power supply: AC: 220V10% · 50Hz Operating current is less than 0.5A;
2. Tripping operation power supply voltage: DC: 88V ~ 220V arbitrary, automatic identification;
3. Two-way trip input, one-way closing input and corresponding twelve auxiliary output empty contacts;
4. Jump, gate current selection: calculated according to 220V: 0.25A, 0.5A, 1.0A, 2.0A, 3.0A, 4.0A, 5.0A;
5. Trip time selection: 20ms ~ 990ms;
6. Closing time selection: 20ms ~ 990ms;
7. Phase separation, three-phase operation selection: phase-separable operation, three-phase operation, switching by split/three-phase button;
8. Manual jump and close function: Manual three-phase tripping, manual three-phase closing, hand-jump with synchronous output, and one pair of hand-opening contacts;
9. Breaker failure: When the breaker failure button is pressed, the analog breaker does not operate, the trip and closing currents are delayed after 1 s, and the current is restored after 20 s.
10. Output normally open, normally closed contact capacity: AC 220V/5A DC 220V/0.5A;
11. Volume: 330mm × 220mm × 180mm;
12. Weight: 6kg.
