壓縮機側止回閥12容許空氣朝下游側之流動,且遮斷空氣朝上游側之流動。在該例中,壓縮機側止回閥12遮斷空氣自第1、第2槽20、30朝壓縮機10之流動。除濕裝置14對自壓縮機10供給之壓縮空氣予以除濕。在該例中,壓縮機側止回閥12設置於除濕裝置14內。The compressor-
第1、第2調壓部22、32包含於壓縮裝置控制部16,為了調整槽內壓力而控制壓縮機10之動作。第1調壓部22在第1模式下動作,在第2模式下不動作,第2調壓部32在第2模式下動作,在第1模式下不動作。The first and second
在第1模式中,第1調壓部22檢測第1槽20內之第1壓力,與該第1檢測壓力相應地控制壓縮機10之作動/非作動。第1調壓部22在第1檢測壓力低於預設之第1下限壓力Pj時使壓縮機10作動,而提高第1槽20內之壓力。又,第1調壓部22在第1檢測壓力為預設之第1上限壓力Pk以上時使壓縮機10停止。其結果為,在第1模式下,第1槽20內之壓力維持在第1下限壓力Pj至第1上限壓力Pk之間。此外,第1下限壓力Pj設定為低於第1上限壓力Pk。In the first mode, the
在第2模式中,第2調壓部32檢測第2槽30內之第2壓力,與該第2檢測壓力相應地控制壓縮機10之作動/非作動。第2調壓部32在第2檢測壓力低於預設之第2下限壓力Pm時使壓縮機10作動,而提高第2槽30內之壓力。又,第2調壓部32在第2檢測壓力為預設之第2上限壓力Pn以上時使壓縮機10停止。其結果為,在第2模式下,第2槽30內之壓力維持在第2下限壓力Pm至第2上限壓力Pn之間。此外,第2下限壓力Pm設定為低於第2上限壓力Pn。In the second mode, the
第1槽通路24係經由壓縮機側止回閥12、除濕裝置14將自壓縮機10送出之壓縮空氣Apo供給至第1槽20之通路。本實施形態之第1槽通路24將除濕裝置14之出口與第1槽20之埠P1相連,而朝第1槽20內導引壓縮空氣Apo。The
第2槽通路34係經由壓縮機側止回閥12、除濕裝置14將自壓縮機10送出之壓縮空氣Apo供給至第2槽30之通路。本實施形態之第2槽通路34將第1槽20之埠S1與第2槽30之埠P2相連,而朝第2槽30內導引通過第1槽20之壓縮空氣Apo。在第2槽通路34設置壓力控制閥52作為第1閥。本實施形態之壓力控制閥52以不遮斷對第1槽20供給由壓縮機10產生之壓縮空氣之通路之方式設置。The
壓力控制閥52在上游側之壓力為特定之第1控制壓力Pv1以上時打開而使壓縮空氣朝下游側流動,在上游側之壓力低於第1控制壓力Pv1時關閉而遮斷空氣之流動。本實施形態之壓力控制閥52設置於第2槽30接收壓縮空氣之供給之通路,控制壓縮空氣Apo朝第2槽30之供給。壓力控制閥52在壓縮空氣Apo之壓力低於第1控制壓力Pv1時關閉,而遮斷壓縮空氣Apo朝第2槽30之流入,在壓縮空氣Apo之壓力為第1控制壓力Pv1以上時打開,而容許壓縮空氣Apo朝第2槽30之流入。The
在本實施形態中,第1控制壓力Pv1設定為高於第1上限壓力Pk。即,由於在第1模式中於第1調壓部22動作之期間,壓縮空氣Apo之壓力不超過第1控制壓力Pv1,故壓力控制閥52維持關閉之狀態,壓縮空氣Apo不會流入第2槽30。In this embodiment, the first control pressure Pv1 is set higher than the first upper limit pressure Pk. That is, since the pressure of the compressed air Apo does not exceed the first control pressure Pv1 during the operation of the
在本實施形態中,第1控制壓力Pv1設定為高於第2下限壓力Pm且低於第2上限壓力Pn。即,在第2模式中於第2調壓部32動作之期間,當壓縮空氣Apo之壓力超過第1控制壓力Pv1時,壓力控制閥52打開,壓縮空氣Apo流入第2槽30。當壓縮空氣Apo之壓力低於第1控制壓力Pv1時,壓力控制閥52關閉,壓縮空氣Apo之流入停止,當壓縮空氣Apo之壓力再次超過第1控制壓力Pv1時,壓縮空氣Apo流入第2槽30。In this embodiment, the first control pressure Pv1 is set to be higher than the second lower limit pressure Pm and lower than the second upper limit pressure Pn. That is, when the pressure of the compressed air Apo exceeds the first control pressure Pv1 during the operation of the
說明本實施形態之動作。
(1)第1模式動作(無法使用架線電力之情形)
由於在集電弓82降下之狀態下,無法使用架線電力,故壓縮裝置控制部16進入第1模式,使第1調壓部22作動,對壓縮機10供給來自車載電源40之車載電源電力。此時,壓縮機10經由第1槽通路24將壓縮空氣Apo供給至第1槽20。所供給之壓縮空氣Apo積存於第1槽20。The operation of this embodiment is explained.
(1) Operation in the first mode (when overhead power cannot be used)
Since the overhead power cannot be used when the
在第1模式下,藉由第1調壓部22,將第1槽20內之壓力維持在第1下限壓力Pj與第1上限壓力Pk之間。由於第1控制壓力Pv1高於第1上限壓力Pk,故壓力控制閥52維持關閉狀態。因此,藉由壓力控制閥52,使得在第1槽20內之壓力低於壓力控制閥52之第1控制壓力Pv1時,壓縮空氣Apo不會自第1槽20朝第2槽30流入。在第1模式下,藉由自第1槽20送出之第1壓縮空氣Ap1而升降裝置86作動,而可將集電弓82升降。In the first mode, the pressure in the
(2)第2模式動作(可使用架線電力之情形)
由於在集電弓82上升且與架線84接觸之狀態下,可使用架線電力,故壓縮裝置控制部16進入第2模式,使第2調壓部32作動,對壓縮機10供給架線電力。此時,壓縮空氣Apo超過第1上限壓力Pk而積存於第1槽20。(2) Operation in the second mode (when overhead power can be used)
Since the overhead line power can be used when the
一旦壓縮空氣Apo之壓力成為第1控制壓力Pv1以上,壓力控制閥52便打開,自第1槽20朝第2槽30送出壓縮空氣Apo,且壓縮空氣Apo積存於第2槽30。在第2模式下,藉由自第1槽20送出之第1壓縮空氣Ap1而升降裝置86作動,而可使集電弓82升降。又,藉由自第2槽30送出之第2壓縮空氣Ap2,可使制動器驅動裝置96及門開閉裝置98作動When the pressure of the compressed air Apo becomes equal to or higher than the first control pressure Pv1, the
(3)遮斷模式動作(遮斷器等之保護電路發揮作用之情形)
在因來自架線84之異常電流而保護電路(例如真空遮斷器)發揮作用時,成為集電弓降下而架線電力無法使用之狀態。在此狀態下,由於無法使用架線電力,故壓縮裝置控制部16切換至第1模式利用車載電源電力使壓縮機10作動,利用來自第1槽20之壓縮空氣Ap1使集電弓升降。在此情形下,空氣壓縮系統100與第1模式同樣地動作。(3) Break mode operation (when the protective circuit such as breaker is working)
When a protective circuit (for example, a vacuum interrupter) functions due to an abnormal current from the
說明如上述般構成之本實施形態之空氣壓縮系統100之作用、效果。The function and effect of the
本實施形態之空氣壓縮系統100具備:壓縮機10;第1槽20,其積存壓縮空氣以用於集電弓升降;第2槽30,其積存壓縮空氣以用於制動器作動;車載電源40,其可與架線84不同地另行供給電力;及控制部,其以下述方式控制壓縮機10:在無法利用架線電力時,將利用車載電源40之電力於壓縮機10產生之壓縮空氣積存於第1槽20,在可利用架線電力時,將利用架線電力於壓縮機10產生之壓縮空氣積存於第2槽30。The
根據此構成,可利用1個壓縮機10將壓縮空氣積存於第1槽20及第2槽30。其結果,與具備另一壓縮機之情形相比,可將空氣壓縮系統小型化。According to this structure, the compressed air can be accumulated in the
在上述之裝置中,利用車載電源40之電力由壓縮機10產生之壓縮空氣可不供給至第2槽30。此時,由於壓縮空氣不會流動至第2槽30,故有效率地在第1槽20積存壓縮空氣。其結果為,可減小車載電源40之容量。In the above-mentioned device, the compressed air generated by the
上述之裝置可具有可遮斷對第2槽30供給壓縮空氣之通路之壓力控制閥52。在此情形下,藉由在第1模式下遮斷壓力控制閥52,而可防止利用車載電源40之電力產生之壓縮空氣供給至第2槽30。The above-mentioned device may have a
上述之壓力控制閥52可以不遮斷對第1槽20供給由壓縮機10產生之壓縮空氣之通路之方式設置。在此情形下,由於即便在壓力控制閥52因何種理由未打開之情形下,亦對第1槽20供給壓縮空氣,故可使集電弓82上升而自架線84受電。The above-mentioned
上述之壓力控制閥52係在特定之第1壓力以上時打開之壓力控制閥,可行的是,利用車載電源40之電力由壓縮機10產生之壓縮空氣之壓力控制為低於第1壓力,利用架線電力由壓縮機10產生之壓縮空氣之壓力控制為高於第1壓力。在此情形下,由於用於開閉狀態與壓力之高低相應地自動地切換之壓力控制閥52,故可無須另行控制。The above-mentioned
在上述之裝置中,壓縮機10在利用車載電源40之電力時,可以較利用架線電力時為低之電壓驅動。在此情形下,由於可以較低之電壓驅動壓縮機10,故可將車載電源40小型化。In the above-mentioned device, the
