关键技术
调相或损坏时，不能发生相间短路;
换相切换时断电时间要短，能满足各类电气设备的用电要求，小于5ms，才会使日光灯不灭和空调不停机。
永磁式换相开关优点：
换相时间快，5毫秒左右;
机械互锁，不会引发短路事故;
可靠性高，机械寿命大于10万次，电气寿命大于15000次;
产品自身功耗小，3W左右;
有过电流保护功能，不需要另配塑壳短路器
具有电压、电流、相位等数据采集并上传;
可选择RS485、无线或电力载波三种模式(需订货时定制)
| 继电器式换相开关 | 可控硅式换相开关 | 5mg左右 |
换相时间 | 20-25mg | 7-l0mg | 5mg左右 |
耗电 | 3W左右 | 60-120W | 3W左右 |
分断能力 | 差 | 差 | 10kA |
机械寿命 | 万次 | 易坏 | ≥10 万次 |
电气寿命 | 差 | 差 | ≥1.5 万次 |
换相时会使部分家用，换相时还会造成短暂灭灯，不影响所有家中所有照明灯具及电器发生停电问题，损坏时发生烧毁电网的事故电器专用电设备的正常工作。
