接下來,利用圖1及圖2說明當主電路1有事故發生,電流檢測器12檢測到過電流的情形下之通常的斷路原理,及本發明實施例1之斷路失敗時的換向式直流斷路器的監視方法。 Next, a general circuit breaking principle in the case where an accident occurs in the main circuit 1 and the current detector 12 detects an overcurrent, and a commutating DC in the case where the disconnection fails in the first embodiment of the present invention will be described with reference to FIGS. 1 and 2. Circuit breaker monitoring method.
圖2的步驟(A)中,當直流電路中流通過大的電流(主電路事故),則步驟(B)中會藉由電流檢測器12檢測到過電流。該過電流的檢測致使驅動指令裝置13發出指令,當基於此將主電路1的電流斷路的情形下,在將主開閉器3開極後一瞬間,通常是於步驟(D)中換向開關5及換向電路形成開關5a被點弧,而形成換向用電容器6、換向開關5、主開閉器3、飽和電抗器8之換向電路2,於步驟(E)中換向用電容器6放電而電容器電壓降低,伴隨換向用電容器6的放電,朝和主電路電流1a相反方向流通換向電流2a。該換向電流2a被重疊至主電路電流1a,當主開閉器3的電流達到零值,則步驟(F)中主開閉器3消弧而換向式直流斷路器14開放,藉此,步驟(L)中事故電流被斷路。 In the step (A) of Fig. 2, when a large current (main circuit accident) flows through the DC circuit, an overcurrent is detected by the current detector 12 in the step (B). The detection of the overcurrent causes the drive command device 13 to issue an instruction. When the current of the main circuit 1 is disconnected based on this, the switch is normally turned on in the step (D) immediately after the main switch 3 is opened. 5 and the commutating circuit forming switch 5a is arced to form the commutating capacitor 6, the commutating switch 5, the main switch 3, the commutating circuit 2 of the saturable reactor 8, and the commutating capacitor in the step (E) 6 is discharged and the capacitor voltage is lowered. With the discharge of the commutation capacitor 6, the commutation current 2a flows in the opposite direction to the main circuit current 1a. The commutation current 2a is overlapped to the main circuit current 1a. When the current of the main switch 3 reaches zero, the main switch 3 is arc-extinguished in step (F) and the commutating DC circuit breaker 14 is opened, whereby the step The accident current in (L) is broken.
此外,當換向開關5及換向電路形成開關5a未藉由驅動指令裝置13的指令而被點弧的情形下,習知是事故電流無法斷路而換向式直流斷路器14會損傷,然後藉由連動來依序開放平時不開放的斷路器以將事故電流斷路,因此事故電流之斷路需花費時間,事故恐怕會蔓延而導致有問題的換向式直流斷路器14所在之變電所全體燒毁。 In addition, when the changeover switch 5 and the commutation circuit forming switch 5a are not arced by the command of the drive command device 13, it is conventional that the accident current cannot be broken and the commutating DC circuit breaker 14 is damaged, and then By interlocking to open the circuit breakers that are not normally open in order to disconnect the accident current, it takes time to break the accident current, and the accident may spread and cause the problematic commutating DC circuit breaker 14 to be the entire substation. burn.
鑑此,本實施例中係設計成,針對依照步驟(C)中換向式直流斷路器14的開放指令而步驟(D)中驅動指令裝置13發出指令致使換向開關5及換向電路形成開關5a點弧(開閉),監視其是否失敗。 For this reason, in the present embodiment, the drive command device 13 is commanded in the step (D) in accordance with the open command of the commutating DC circuit breaker 14 in the step (C), so that the commutation switch 5 and the commutation circuit are formed. Switch 5a is arced (opened and closed) to monitor whether it has failed.
作為其監視方法,於步驟(G)中藉由測定部亦即計測用變壓器15測定換向用電容器6的電壓,若檢測單元16檢測到該測定出的換向用電容器6的電壓沒有變化(電壓變動),亦即換向電路2中沒有換向電流2a通電,便判斷換向開關5及換向電路形成開關5a點弧失敗,於步驟(H)中藉由對輔助繼電器通電而檢測到異常,於步驟(I)中伴隨輔助繼電器接點的動作發送訊號至隨時確認變電所的異常或狀態並進行機器操作之監視裝置17,以發出警報(蜂鳴器等)並顯示。其後,於步驟(J)中對關連斷路器給予開放指令,於步驟(K)中關連斷路器被開放而事故電流被斷路(圖2步驟(L))。 In the monitoring method, the voltage of the commutation capacitor 6 is measured by the measuring transformer 15 which is the measuring unit in the step (G), and the detecting unit 16 detects that the voltage of the measured switching capacitor 6 has not changed ( Voltage variation), that is, when the commutation current 2a is not energized in the commutation circuit 2, it is judged that the commutation switch 5 and the commutation circuit form the switch 5a to fail the arc, and it is detected in step (H) by energizing the auxiliary relay. Abnormality, in the step (I), the operation of the auxiliary relay contact is transmitted to the monitoring device 17 that confirms the abnormality or state of the substation and operates the machine to issue an alarm (buzzer, etc.) and display it. Thereafter, an open command is given to the connected circuit breaker in step (J), in which the circuit breaker is opened and the accident current is disconnected (step (L) of Fig. 2).
藉由上述監視裝置17的警報、顯示,監視裝置17的管理者便能夠知道異常,且藉由從監視裝置17發出開放指令至當換向式直流斷路器14有問題時將事故電流斷路 所必需之更高電壓的該變電所的上位斷路器及該變電所的其他迴路的饋電用斷路器,便能立即地將事故電流斷路。 By the alarm and display of the monitoring device 17, the manager of the monitoring device 17 can know the abnormality and open the accident current by issuing an open command from the monitoring device 17 to when there is a problem with the commutating DC circuit breaker 14. The higher-voltage upper-level circuit breaker of the substation and the feeder circuit breaker of the other circuit of the substation can immediately disconnect the accident current.
藉由這樣的本實施例,即使發生事故等問題,仍可立即檢測該問題所造成之事故電流,迅速地將事故電流從直流電源隔離開來,能夠防止事故的蔓延,因此不會使被害擴大至變電所全體,可將被害減至最小限度來防止事故。 According to this embodiment, even if an accident or the like occurs, the accident current caused by the problem can be immediately detected, and the accident current can be quickly isolated from the DC power source, and the accident can be prevented from spreading, so that the victim is not enlarged. To the entire substation, the damage can be minimized to prevent accidents.
另,本發明不限定於上述實施例,尚包含各種變形例。舉例來說,上述實施例是為了以便於理解本發明之方式來說明而詳細說明,並非限定於一定要具備所說明的所有構成。此外,可將某一實施例的構成的一部分置換成其他實施例的構成,又,亦可在某一實施例的構成追加其他實施例的構成。此外,針對各實施例的構成的一部分,可追加、刪除、置換為其他構成。 Further, the present invention is not limited to the above embodiment, and various modifications are also included.
