電氣成套設備的斷路器的控制,不知道大家了解的多不多,如果不了解的話那就和小編一起來看看吧。
I don't know how much you know about the circuit breaker control of electrical equipment. If you don't know, let's take a look with Xiaobian.
電氣成套設備中的斷路器的控制,就是控制其合閘和分閘。
The control of circuit breaker in electrical equipment is to control its closing and opening.
按控制地點分有就地控制和集中控制兩種。在斷路器附近用手操作斷路器的手動操作機構或采用按鈕控制(通過電磁鐵或電動機)完成合閘、分閘任務,就是就地操作。
According to the control location, there are local control and centralized control. In the vicinity of the circuit breaker, manually operate the manual operating mechanism of the circuit breaker or use the button control (through electromagnet or motor) to complete the closing and opening tasks, which is the local operation.
這種方式可以一節省投資、節省電纜和二次設備。集中控制是在主控制室進行的,如發電機、主變壓器、母線分段和母線聯絡斷路器等上要設備,均采用集中控制方式。這種控制方式中被控制的斷路器和主控制室之間一般有幾十米數百米距離,所以也稱為“遠方控制”。
This way can save investment, cable and secondary equipment. Centralized control is carried out in the main control room, such as generator, main transformer, bus section and bus tie circuit breaker. In this control mode, the distance between the controlled circuit breaker and the main control room is generally tens of meters to hundreds of meters, so it is also called "remote control".
對斷路器的控制是通過輔助電路實現的。在主控制室的控制屏上應裝有能發出合閘、分閘命令的控制開關或按鈕,在斷路器上應有執行命令的操動機構(即合閘、分閘線圈)。控制開關和操動機構之間通過控制電纜連接起來。完成斷路器合閘、分閘任務的電氣回路稱為控制電路。控制電路按操作電源的種類可以分為直流操作和交流操作兩類;按采用的接線和設備分,有強電控制和弱電控制兩類。
The control of circuit breaker is realized by auxiliary circuit. The control panel in the main control room shall be equipped with a control switch or button that can send the closing and opening commands, and the circuit breaker shall be equipped with an operating mechanism (i.e. closing and opening coils) that can execute the commands. The control switch and the operating mechanism are connected by a control cable. The electrical circuit that completes the closing and opening tasks of circuit breaker is called control circuit. According to the types of operation power supply, the control circuit can be divided into DC operation and AC operation; according to the adopted wiring and equipment, there are strong current control and weak current control.
