1. Types and Implications of HKW1 Intelligent Universal Circuit Breaker:

2. The scope of application of intelligent universal circuit breaker:

HKW1 series intelligent universal circuit breakers are suitable for 50 Hz AC, rated voltage to 690 V and below, rated current 400A-6300A distribution network, used to distribute electric energy and protect lines and power supply equipment from overload, undervoltage, short circuit, single-phase grounding and other faults. The circuit breaker has intelligent protection function and precise selective protection, which can improve the reliability of power supply and avoid unnecessary power outage. At the same time, it has an open communication interface, which can carry out four remotes to meet the requirements of centralized control center and automation system. The circuit breaker has a pulse withstand voltage of 8000V at an altitude of 2000m (revised according to standard at different altitudes, up to 12000V). The circuit breaker rod, without intelligent tripping device and sensor can be used as isolator, marked as uuuuuuuuuuuu The /u circuit breaker meets GB14048.2 low voltage switchgear and control equipment low voltage circuit breaker and IEC947-2 low voltage switchgear and control equipment circuit breaker standards.

塑壳断路器主要参数：

智能型万能式断路器工作原理：

1、智能型万能式断路器为立体布置形式，触头系统、瞬时过电流脱扣器左右侧板均安装在一块绝缘板上；

2、上部装有灭弧系统，操作机构可装在正前方或右侧面，有“分”、“合”指示及手动断开 按钮；

3、其左上方装有分励脱扣器，背部装有与脱扣半轴相连的欠电压脱扣器；

4、速饱和电流互感器或电流电压变换器套在下母线上；

5、欠电压延时装置、热继电器或半导体脱扣器可分别装在下方；

6、HKW15-1000、 1600、2500、4000断路器为立体布置形式，由底架、侧板、横梁组成框架，每相触头系统安装在底架上，上面装灭弧室；

7、操作机构在断路器右前方，通过主轴与触头系统相连；

8、电动操作机构通过方轴与机构连成一体装于断路器下部，作为断路器的贮能或直接闭合之用，贮能后的闭合由释能电磁铁承担；

9、在左侧板上方装有防回跳机构，以防止断路器在断开时弹跳；

10、各种过电流脱扣器按不同要求装在断路器下方，欠电压，分励脱扣器及电动操作控制部分装在左侧，其中欠电压、分励脱扣器通过脱扣器与放大机构相连，以减少断路器的脱扣力；

11、12对辅助触头供用户联接二次回路用，面板上有显示断路器工作位置的指示牌“1”“0”和“贮能”指示，还有供合闸及分闸用的按钮“1”“0”（均按下）；

12、HKW15-1000、 1600断路器附有正面手动操作手柄；

13、HKW15-2500、4000附有检修用的手动操作手柄（均可卸下）。
