本發明一種自動復閉器改良裝置，可以改善習有技藝中自動復閉器無法自力測試電力迴路中斷路器電源側與負載側的電力狀態，於異常狀態時自動閉鎖，停電時或於停電後再復電時主斷路器尚未復閉前將電力迴路所有斷路器啟斷，復電時主斷路器復閉後，發出順序復閉信息依序復閉，該自動復閉器改良裝置以主斷路器為主，可控制整個電力迴路所有斷路器自動順序跳脫復閉，節省人力達到經濟性及用電的安全性。 The invention discloses an improved automatic reclosing device, which can improve the problem that the automatic reclosing device in the prior art cannot independently test the power status of the power supply side and the load side of the circuit breaker in the power circuit. It can automatically lock in an abnormal state, and open all the circuit breakers in the power circuit before the main circuit breaker is restored during a power outage or after a power outage. After the main circuit breaker is restored, it will send out a sequential restoration information and restore in sequence. The improved automatic reclosing device is mainly based on the main circuit breaker, and can control all the circuit breakers in the entire power circuit to automatically trip and restore in sequence, saving manpower to achieve economy and safety of electricity use.
習知技藝中，傳統自動復閉器是一常見設備，在台灣歷次大停電的狀況下，發現絕大部份傳統自動復閉器完全沒有發揮自動復閉功能，並且實際上製造許多的工安事故及造成許多人員財產上的損失，應該必須改善其缺失，傳統的自動復閉器沒有自我偵測電力迴路系統電力狀態，當停電時因沒有外接支援電源提供分路斷路器跳脫斷電，如此會導致當市電復電時，當主斷路器復閉投入送電時，由於分路開關都沒有啟斷斷電的狀態，等同有載之下送電，非常危險！並且傳統自動復閉器沒有對該電力迴路下游斷路器確認是否有閉合或啟斷狀態的偵測判讀也是非常嚴重的缺失；目前市面上許多主高壓斷路器盤有設置該設備，其分路高壓斷路器盤部份也 有裝置該自動復閉器設備，因為分路的斷路器停電時斷路器沒有啟斷，使分路自動復閉裝置完全毫無作動，導致在電力迴路系統中增加故障點來源，應改善由主斷路器盤的自動復閉器可以順序控制所有其它斷路器盤自動跳脫與順序自動復閉的功能。 In the field of knowledge and technology, traditional automatic reclosers are a common device. In the cases of major power outages in Taiwan, it was found that most traditional automatic reclosers did not fully demonstrate their automatic reclosing function, and actually caused many industrial accidents and caused many casualties and property losses. This defect must be improved. Traditional automatic reclosers do not have self-detection of the power status of the power circuit system. When there is a power outage, there is no external support power supply to provide branch circuit breakers to trip and cut off power. This will cause when the city power is restored and the main circuit breaker is switched on to supply power, the branch switches will not be turned on and off to cut off power, which is equivalent to supplying power under load, which is very dangerous! In addition, the traditional automatic recloser does not have the ability to detect and judge whether the downstream circuit breaker of the power loop is closed or opened, which is a very serious deficiency. Currently, many main high-voltage circuit breaker panels on the market are equipped with this device, and the branch high-voltage circuit breaker panels are also equipped with this automatic recloser. Because the branch circuit breaker does not start when the power is cut off, the branch automatic recloser does not work at all, resulting in an increase in the source of fault points in the power loop system. The function of the automatic recloser of the main circuit breaker panel to sequentially control the automatic tripping and sequential automatic reclosing of all other circuit breaker panels should be improved.
習知技藝中，該自動復閉器一般的控制電源的主要來源來自於該電力迴路比壓器二次側，所以當該電力迴路停電時，該自動復閉器就失去電力來源，所以在失去控制電力電能情況下，就無法有電力驅動該開關作動啟斷或跳脫的動作且習知技藝中傳統自動復閉器復閉送電前無法對下游的斷路器或整個電力系統確認是否有接續負載的狀態，是其重大缺失，會造成有載之下送電會造成事故，是電力迴路故障的來源之一，不得不慎重考慮其危險性！一般在低壓電力盤上的斷路器也沒有設備偵測感應裝置也沒有裝設不足電壓跳脫裝置，所以該斷路器在停電時不會跳脫或啟斷，以至於該自動復閉器一般沒有裝設在低壓電力迴路，習有技藝中所有的自動復閉器產品無法解決上述共同的問題。 In the conventional art, the main source of control power for the automatic recloser is from the secondary side of the voltage transformer in the power circuit. Therefore, when the power circuit fails, the automatic recloser loses its power source. Therefore, when the control power and electric energy are lost, there is no power to drive the switch to start or trip. In addition, the conventional automatic recloser in the conventional art cannot confirm whether the downstream circuit breaker or the entire power system is in a state of continuous load before reclosing and transmitting power. This is a major defect, which may cause accidents when transmitting power under load. It is one of the sources of power circuit failures, and its danger must be carefully considered! Generally, the circuit breaker on the low-voltage power panel is not equipped with a detection sensor or an undervoltage tripping device, so the circuit breaker will not trip or start during a power outage, so the automatic recloser is generally not installed in the low-voltage power circuit. All the automatic recloser products in the conventional technology cannot solve the above common problems.
習知技藝中，該自動復閉器即使在高壓電力迴路中，一般祇有在主高壓斷路器盤的電力迴路才有裝設電壓偵測的電壓保護電驛，一般的分路盤則沒有裝設該電壓保護電驛，當高壓電力迴路中有電壓保護電驛時，偵測電壓的作動以該電壓電驛為準，該自動復閉器內部的電壓偵測內容不為台電所認可，高壓斷路器盤上的感測元件即保護電驛全世界(含台電)都非常的重視，一定要有世界IEEE認可經台電核准之電驛才可使用於高壓斷路器的配電盤，所以當該電力迴路停電時祇有主斷路器盤的高壓斷路器會啟斷，其它分路以下斷路器皆沒有電源驅動使該斷路器啟斷；而在低壓斷 路器盤中，除了沒有上述控制電力來源外，一般也沒有其它電力感測元件，導致沒有動力來源使該斷路器跳脫或啟斷，習有技藝中所有的自動復閉器產品無法解決上述共同的問題。 In the known technology, even in the high-voltage power circuit, the automatic recloser is usually only installed with a voltage protection stop for voltage detection in the power circuit of the main high-voltage circuit breaker panel. The general branch panel is not equipped with the voltage protection stop. When there is a voltage protection stop in the high-voltage power circuit, the action of the voltage detection is based on the voltage stop. The voltage detection content inside the automatic recloser is not recognized by Taipower. The sensing element on the high-voltage circuit breaker panel, i.e. the protection stop, is highly valued by the world (including Taipower) and must be recognized by the world. Only the electric stops approved by IEEE and approved by Taipower can be used in the distribution board of high-voltage circuit breakers. Therefore, when the power circuit is out of power, only the high-voltage circuit breaker in the main circuit breaker panel will be activated, and the circuit breakers below the other branches will not have power to drive the circuit breaker to activate; and in the low-voltage circuit breaker panel, in addition to the lack of the above-mentioned control power source, there are generally no other power sensing components, resulting in no power source to trip or activate the circuit breaker. All the automatic recloser products in the conventional technology cannot solve the above common problems.
習知技藝中，該自動復閉器於多層次的電力迴路系統中，習有的該自動復閉器只能在一主斷路器盤做復閉送電的功能，電力迴路停電時由於沒有控制電源，所以所有的分路盤就沒有電力提供使該分路盤的斷路器啟斷，若是主盤以下的斷路器都沒有被啟斷該斷路器都是在閉合的情況下，當復電復閉送電時有可能等同有載下送電，可能會燒毀設備，或造成自動復閉器閉鎖斷電，會有工安上的疑慮，並且在習知技藝中，該自動復閉器無法使該電力迴路系統上所有的斷路器依序投入復閉送電，習知技藝以調整時間的差異性達成該功能，但事實上在高壓迴路與低壓迴路上的斷路器於停電時並沒有被啟斷，又該自動復閉器於停電時沒有控制電源，電力迴路復電時，所有的自動復閉器又全部有電，無法達到順序送電復閉的功能，習有技藝中所有的自動復閉器產品無法解決上述共同的問題。 In the prior art, the automatic recloser in a multi-layer power circuit system can only perform the function of reclosing and power transmission in a main circuit breaker panel. When the power circuit is out of power, there is no control power, so all the branch panels have no power to open the circuit breakers of the branch panels. If the circuit breakers below the main panel are not opened and the circuit breakers are all closed, when the power is restored and the power is transmitted, it may be equivalent to the power transmission being unloaded, which may burn the equipment or cause the automatic recloser to lock and cut off the power, which will cause concerns about industrial safety. , and in the prior art, the automatic recloser cannot make all the circuit breakers on the power circuit system resume power supply in sequence. The prior art achieves this function by adjusting the time difference, but in fact, the circuit breakers on the high-voltage circuit and the low-voltage circuit are not activated during the power outage, and the automatic recloser does not control the power supply during the power outage. When the power circuit is restored, all the automatic reclosers are powered again, and the function of sequential power supply and reclosing cannot be achieved. All the automatic recloser products in the prior art cannot solve the above common problems.
習知技藝中，該自動復閉器當高壓迴路若停電，而以下的斷路器沒有被啟斷，此時一般大樓皆有自備發電機，當該發電機啟動發電送至電力迴路時，該電力電壓可能經匯流排或電纜線經變壓器到高壓迴路，此時在高壓盤上做維修工作人員有觸及高壓電的危險，所以當停電時，主要的斷路器應先啟斷較安全，而習有技藝中所有的自動復閉器產品無法解決上述共同的問題。 In the conventional technology, if the high-voltage circuit is cut off and the following circuit breakers are not activated, the general building has its own generator. When the generator is started to generate electricity and sent to the power circuit, the power voltage may be transmitted to the high-voltage circuit through the bus or cable through the transformer. At this time, the maintenance workers on the high-voltage panel are in danger of touching the high-voltage electricity. Therefore, when the power is cut off, the main circuit breaker should be activated first for safety. All the automatic recloser products in the conventional technology cannot solve the above common problems.
綜上所述，習有技藝中該自動復閉器由於沒有自我偵測電力迴路狀態功能，並且沒連結該斷路器的電源側與負載側，在低電迴路系統 皆無法使用，尤其在停電後無法啟斷的缺失；再者一般使用於中高壓電力系統上，該自動復閉器其資訊來自保護電驛的接點狀態，當跳脫迴路的控制電源有疑慮的狀況下，會造成沒有信號輸入，造成判讀訊息可能錯誤，又當控制電源因故如保險絲燒掉也可能造成失能，一般而言習有技藝中的自動復閉器一點也不自動，理當稱為被動復閉器，其真正的作用大約祇是一個控制電驛，加上一個時間電驛如此的功能而已；因此實際自動復閉器的功能，當失去電力停電時電力系統應該能夠順序由上而下對於斷路器一段一段的能自動啟斷的功能，而當復電時，能自動偵測電力系統狀態正常時，應該可由該電力系統順序由上而下對於斷路器一段一段的能夠自動閉合投入送電，當該自動復閉器若遇到異常狀態時，無論是由該斷電器的電源側或該斷路器的負載側，皆能在電力迴路的控制電源已經沒電失能的情況下，而能夠故障狀態下自動閉鎖，如此的基本功能要求，習有技藝中所有的自動復閉器產品無法解決上述共同問題。 In summary, the conventional automatic recloser does not have the function of self-detecting the power circuit status and is not connected to the power supply side and the load side of the circuit breaker. It cannot be used in low-power circuit systems, especially when it cannot be started after a power outage. Moreover, it is generally used in medium and high voltage power systems. The information of the automatic recloser comes from the contact status of the protection switch. When the control power of the trip circuit is in doubt, there will be no signal input, resulting in possible errors in the information reading. When the control power fails for some reason, such as a fuse burning out, it may also cause disability. Generally speaking, the automatic recloser in the traditional technology is not automatic at all, and should be called a passive recloser. Its real function is just a control switch, plus a time The function of the electric stop is just this; therefore, the actual function of the automatic recloser is that when the power is lost, the power system should be able to automatically start the circuit breakers one by one from top to bottom, and when the power is restored, it can automatically detect that the power system is in a normal state, and the power system should be able to automatically close the circuit breakers one by one from top to bottom. When the power is turned on, if the automatic recloser encounters an abnormal state, whether it is from the power side of the circuit breaker or the load side of the circuit breaker, it can automatically lock in the fault state when the control power of the power loop has been depleted. Such basic functional requirements, all automatic recloser products in the existing technology cannot solve the above common problems.
為解決上述習知技藝的問題，本發明一種自動復閉器改良裝置，可以改善習有技藝中自動復閉器無法自力測試電力迴路中斷路器電源側與負載側的電力狀態，於異常狀態時自動閉鎖，停電時或於停電後再復電時主斷路器尚未復閉前將電力迴路所有斷路器啟斷，復電時主斷路器復閉後，發出順序復閉信息依序復閉，該自動復閉器改良裝置以主斷路器為主，可控制整個電力迴路所有斷路器自動順序跳脫復閉，節省人力達到經濟性及用電的安全性。 In order to solve the above problems of the prior art, the present invention discloses an improved automatic reclosing device, which can improve the problem that the automatic reclosing device in the prior art cannot independently test the power status of the power supply side and the load side of the circuit breaker in the power circuit, and automatically locks in an abnormal state, and opens all the circuit breakers in the power circuit before the main circuit breaker is restored during a power outage or after a power outage. After the main circuit breaker is restored when the power is restored, a sequential restoration information is issued to restore in sequence. The improved automatic reclosing device is mainly based on the main circuit breaker, and can control all the circuit breakers in the entire power circuit to automatically trip and restore in sequence, saving manpower to achieve economy and safety of electricity use.
為達上述目的，本發明一種自動復閉器改良裝置，在電力迴 路主斷路器電源側與負載側設置偵測電力迴路的電路，與一多重電源輸入的控制電源例如不斷電供電系統、電池組、電容跳脫裝置的裝置，至少包括電源側與負載側的輸入電源與外接電能，該裝置最好有一儲能電力的設置，以利停電時有動力可以使斷路器啟斷或跳脫或故障異常時能閉鎖的電源，內鍵有微處理器單元，能夠停電時依順序將該主斷路器啟斷再啟斷其它斷路器，復電時依順序將該主斷路器閉合，再閉合其它斷路器，當偵測異常時並可閉鎖斷路器的跳脫機構使該斷路器無法閉合或啟斷，更佳的方法可以自行判讀該主斷路器本體的電力狀態，並能偵測其它斷路器的電力狀態，例如閉合、啟斷狀態補助接點，以及外部指令、電驛狀態接點做為補助的參數，使該自動復閉器的判讀更為正確，最佳的方法，在主斷路器在復閉投入送電前必須將電力迴路中的全部斷路器先跳脫，可避免有載之下送電造成危險，並達成一只自動復閉器改良裝置可順序自動啟斷多台斷路器及可順序自動復閉多台斷路器的功能。 To achieve the above-mentioned purpose, the present invention provides an improved automatic reclosing device, which is provided with a circuit for detecting the power circuit on the power side and the load side of the main circuit breaker of the power circuit, and a control power source with multiple power inputs, such as an uninterruptible power supply system, a battery pack, and a capacitor tripping device, at least including the input power on the power side and the load side and an external The device preferably has a power storage device, so that when there is a power outage, there is power to enable the circuit breaker to start or trip or the power supply can be locked when there is an abnormal fault. The internal key has a microprocessor unit, which can start the main circuit breaker and then start other circuit breakers in sequence when there is a power outage. When the power is restored, the main circuit breaker is closed in sequence, and then the other circuit breakers are closed. When an abnormality is detected, the tripping mechanism of the circuit breaker can be locked to prevent the circuit breaker from closing or opening. A better method is to judge the power status of the main circuit breaker and detect the power status of other circuit breakers, such as the closing and opening state auxiliary contacts, as well as external instructions and electric stop state contacts as auxiliary parameters, so that the The automatic reclosing device has a more accurate interpretation. The best method is to trip all the circuit breakers in the power circuit before the main circuit breaker is reset and put into power transmission. This can avoid the danger caused by power transmission under load and achieve the function of an automatic reclosing device to automatically start and automatically reclose multiple circuit breakers in sequence.
為達上述目的，本發明一種自動復閉器改良裝置，當電力迴路停電時，防止該電力系統中若有自備發電機設備，該發電機在30秒~3分鐘內會啟動，該自動復閉器改良裝置內部必須有主斷路器電源停電後計時延遲電路，確定該自備發電機沒有送電後，才啟斷該分路的斷路器開關，並依順序將主斷路器以下其分路的斷路器皆啟斷，當該電力迴路復電時，較佳的方式也有一計時延遲電路並偵測欲復閉的斷路器電源側電力迴路是否有欠相、逆相異常狀態，偵測該斷路器負載側是否有反相電源(逆送電)，當電源側與負載側偵測該電力迴路有異常狀態時，發出一閉鎖訊號將該斷路器內部的跳脫機構閉鎖，該斷路器無法復閉投入閉合或啟斷，當電源側與負載側 皆沒有異常狀態發生時，該自動復閉器改良裝置發出一復閉訊息先使該主斷路器復閉投入送電閉合，該自動復閉器改良裝置會自行判讀該主斷路器所有狀態，若投入失敗則重新上述動作再投入，一般而言若復閉三次失敗，則停止發出訊息，並自行閉鎖該自動復閉器改良裝置停止作動，如此有自我偵測與保護的作用，若是電力迴路恢復正常狀態，再依該自動復閉器改良裝置內部微處理器單元設定程式依設定順序復閉其它斷路器，達成該自動復閉器改良裝置一只可順序自動復閉多台斷路器的功能。 To achieve the above purpose, the present invention provides an improved automatic reclosing device. When the power circuit is out of power, if there is a self-contained generator in the power system, the generator will start within 30 seconds to 3 minutes. The improved automatic reclosing device must have a time delay circuit after the main circuit breaker power is cut off. After confirming that the self-contained generator is not supplying power, the circuit breaker switch of the branch circuit is turned off, and the self-contained generator is turned off according to the time delay circuit. The main circuit breaker and its branch circuit breakers are all opened in sequence. When the power circuit is restored, the better way is to have a time delay circuit and detect whether the power circuit on the power side of the circuit breaker to be restored has an abnormal state of phase loss or reverse phase, and detect whether there is reverse power (reverse power transmission) on the load side of the circuit breaker. When the power side and the load side detect that the power circuit has an abnormal state, a lock signal is issued to close the circuit breaker. The trip mechanism inside the device is locked, and the circuit breaker cannot be reset to close or open. When there is no abnormal state on the power side and the load side, the automatic reset device improves the device to send a reset message to reset the main circuit breaker to close the power supply. The automatic reset device improves the device to automatically read all the states of the main circuit breaker. If the reset fails, the above action will be repeated. Generally speaking, if the reset If it fails three times, the message stops being sent and the automatic reclosing device stops working automatically. This has the function of self-detection and protection. If the power circuit returns to normal, the other circuit breakers will be reset in the set sequence according to the setting program of the microprocessor unit inside the automatic reclosing device, so that the automatic reclosing device can automatically reset multiple circuit breakers in sequence.
