📖 Terms & Definitions / 术语和定义 ai_extracted
- 并联切换 parallel switching / parallel switching
- 先合上备用电源断路器，再跳开工作电源断路器，或者先合上工作电源断路器，再跳开 备用电源断路器的切换方式，切换过程中用电设备不会断电。
- First close the standby power circuit breaker, then trip the working power circuit breaker; or first close the working power circuit breaker, then trip the standby power circuit breaker. In this switching method, the electrical equipment will not experience a power outage during the switching process.
- 串联切换 series switching / series switching
- 先跳开工作电源断路器再合上备用电源断路器的切换方式，切换过程中用电设备会瞬间 断电。
- The switching method of first opening the working power circuit breaker and then closing the standby power circuit breaker will cause the electrical equipment to experience a momentary power interruption during the switching process.
- 同时切换 simultaneous switching / simultaneous switching
- 同时发出跳闸指令和合闸指令的切换方式，由于断路器合闸所需的时间大于跳闸所需的 时间，切换过程中用电设备仍会瞬时断电，是一种断电时间较短的串联切换方式。
- The switching method that simultaneously issues trip and close commands results in a momentary power interruption for electrical equipment during the switching process, as the time required for circuit breaker closing is longer than that for tripping. This is a series switching method with a short power outage duration.
- 快速切换 fast switching / fast switching
- 在母线残压与备用电源电压第一次反相位之前合上备用电源断路器，是一种延时最短、 合闸冲击电流最小的切换方式。
- Closing the standby power circuit breaker before the first reverse phase between the bus residual voltage and the standby power supply voltage is a switching method with the shortest delay and the minimum closing inrush current.

- DL / T 1073 — 2007 6 同相位切换 in-phase switching 在母线残压与备用电源电压第一次反相位之后，两者再次同相位时合上备用电源断路器， 是一种延时较长的切换方式。
- DL/T 1073 — 2007 6 In-phase switching A switching method with a relatively long delay, in which the backup power circuit breaker is closed when the residual voltage of the bus and the voltage of the backup power source are in phase again after their first out-of-phase occurrence.
- 残压切换 residual voltage switching / residual voltage switching
- 母线残压较低时才合上备用电源断路器，是一种延时较长的切换方式。
- Closing the standby power circuit breaker only when the residual voltage of the busbar is relatively low is a switching method with a longer delay.

- 包括由工作电源切向备用电源和由备用电源切向工作电源两个方向的切换。
- Including switching in two directions: from the working power supply to the standby power supply, and from the standby power supply to the working power supply.
