Main parameters of plastic case circuit breaker:

The working principle of intelligent universal circuit breaker:

1. Intelligent universal circuit breaker is in three-dimensional arrangement. The left and right side plates of contact system and instantaneous overcurrent tripper are all installed on an insulating board.

2. The upper part is equipped with arc extinguishing system. The operation mechanism can be installed in front or right side, with "split" and "close" instructions and manual disconnection buttons.

3. The upper left part is equipped with a shunt tripper, and the back part is equipped with an undervoltage tripper connected with the half-shaft of the tripping.

4. The speed-saturated current transformer or current-voltage converter is sleeved on the lower bus.

5. Undervoltage delay devices, thermal relays or semiconductor trippers can be installed below.

6. HKW 15-1000, 1600, 2500 and 4000 circuit breakers are three-dimensional layout. They are composed of chassis, side plate and cross beam. Each phase contact system is installed on the chassis and arc extinguishing chamber is installed on it.

7. The operating mechanism is in front of the right of the circuit breaker and is connected with the contact system through the spindle.

8. The electric operating mechanism is connected with the mechanism through a square axis and is installed at the lower part of the circuit breaker as the energy storage or direct closure of the circuit breaker. The closure of the energy storage is undertaken by the release electromagnet.

9. Anti-jump mechanism is installed above the left panel to prevent the circuit breaker from bouncing when it is disconnected.

10. Various over-current trippers are installed under circuit breakers according to different requirements. Under-voltage, excitation trippers and electric operation control parts are installed on the left side. Among them, under-voltage and excitation trippers are connected with amplifier through trippers to reduce the tripping force of circuit breakers.

11 and 12 pairs of auxiliary contacts are used to connect the secondary circuit. On the panel, there are signs "1", "0" and "energy storage" indicating the working position of the circuit breaker, and buttons "1" and "0" for closing and opening.

12. HKW 15-1000 and 1600 circuit breakers are equipped with front manual operation handles.

13. HKW 15-2500 and 4000 are equipped with manual operation handles for maintenance (all can be removed).
