Description
本案是一種關於具有備用電源的電容跳脫裝置，特別是關於外觀指示清楚、容易安裝、易辨識並且具備內部可相互支援電能之電容跳脫裝置，尺寸為習有尺寸一半左右，有分別於昔有技藝必須外接續電源再切換，以及提供一種最簡易的換修技巧，可增強其供電品質的方法與其改良裝置。 This case is a kind of capacitor tripping device with backup power supply, especially for the capacitor jumper with clear appearance, easy to install, easy to identify and with internal mutual support energy. The size is about half of the size of the custom, which is different from the previous one. There are skills that must be connected to the power supply and then switched, and provide an easy-to-replace repair technique to enhance the power supply and its improved device.
電容跳脫裝置(Capactor Trip Device,CTD)是一種非常普遍使用的產品，但往往讓人忽略它的重要性！曾有高壓斷路器(CB)***造成事故，當品管人員在電子儀表上調閱故障記錄時，發現一片空白，並發現電驛專用電容跳脫裝置沒有動作，導致高壓CB沒有隔離事故，造成二次事故。 所以電容跳脫裝置元件雖小，但必須慎選足夠的容量及放電時間，否則事故發生時，高壓CB還是無法有效隔離事故。一般電容跳脫裝置是作為VCB(真空斷路器)或GCB(瓦斯斷路器)跳脫迴路的電源供應，或者保護電驛的工作電源，可利用電容跳脫裝置的電源供應。因此在VCB斷電後，若想要自動再投入供電，必須小心處理。特別是如果想要在台電停電，且情況是VCB因過電流保護電驛偵測到負載的短路故障動作跳脫後，則不建議在故障尚未清除之前作自動復閉供電的動作。 Capactor Trip Device (CTD) is a very popular product, but it is often overlooked! There was an accident caused by the explosion of a high-voltage circuit breaker (CB). When the quality control personnel read the fault record on the electronic instrument, it found a blank, and found that the electric capacitor-free capacitor tripping device did not operate, resulting in no high-voltage CB isolation accident, resulting in Second accident. Therefore, the components of the capacitor tripping device are small, but sufficient capacity and discharge time must be carefully selected. Otherwise, the high-voltage CB cannot effectively isolate the accident when an accident occurs. The general capacitor tripping device is used as a power supply for a VCB (vacuum circuit breaker) or GCB (gas circuit breaker) tripping circuit, or a working power source for protecting the power, and the power supply of the capacitor tripping device can be utilized. Therefore, after the VCB is powered off, if you want to automatically re-power, you must handle it carefully. In particular, if you want to power off the power station, and the situation is that VCB detects the short-circuit fault of the load due to over-current protection, it is not recommended to automatically reset the power supply before the fault has been cleared.
高壓斷路器(H.V.CB)，是接受保護電驛(Relay)的指令，做為是否跳脫高壓斷路器，以將主供電幹線(在台灣，是指台灣電力公司的供電幹線)將事故源隔離。因此該斷路器如果不能如期在某一事業單位(受電方)發生短路事故時立即跳脫，將會造成高壓斷路器(H.V.CB)損壞，而擴及到影響主供電幹線供應電源給其他的事業單位(受電方)，造成連鎖性的產業損失。高壓斷路器能否及時跳脫，受控於保護電驛(Relay)是否能即時發出指令。因此，當提供保護電驛的工作電源有問題時，該保護電驛就不會動作；該保護電驛就不會動作時，高壓CB在事故發生時也就不會動作，無法隔離事業單位的事故點，造成嚴重的二次事故，甚至影響台電供電饋線跳脫！不可不慎。由於此高危險性的工安事件常因誤判而產生意外，於是供電幹線的業者(台灣電力公司)為防止電驛於短路事故時，因電壓驟降無法動作觸發斷路器跳脫，及因比流器飽和遲緩動作，要求事業單位要按照規定裝設置保護系統，才會答應供電。主要的規定內容是：採比壓器二次側電源供應時，應輔以電容跳脫裝置(CTD)或輔以電容跳脫裝置再併接不斷電系統(UPS)，且供電子式或數位式電驛使用之電容跳脫裝置(CTD)，不得接供斷路器或其他設備使用。這是理想，但意外常常來自於理想狀況下，實務上不斷電系統(UPS)一年、兩年後幾乎都會故障。但是事業單位卻不會察覺到，通常都是有短路事故時，發現高壓斷路器(H.V.CB)不會跳脫，發現不斷電系統(UPS)無法供應工作電源給保護電驛(Relay)，但為時已晚。 The high-voltage circuit breaker (HVCB) is a command to accept the relay, as a high-voltage circuit breaker, to isolate the main source of power (in Taiwan, the power supply line of Taiwan Power Company) . Therefore, if the circuit breaker cannot jump off immediately in the event of a short-circuit accident in a certain business unit (power receiving party), the high-voltage circuit breaker (HVCB) will be damaged, and the power supply to the main power supply mains will be extended to other businesses. The unit (power receiving party) causes a chain of industrial losses. Whether the high-voltage circuit breaker can jump in time is controlled by whether the relay can immediately issue an instruction. Therefore, when there is a problem with the working power supply for protecting the power, the protection power will not operate; when the protection power will not operate, the high voltage CB will not operate when the accident occurs, and it is impossible to isolate the business unit. The accident point caused a serious secondary accident and even affected the Taipower power supply feeder to jump off! Don't be careless. Because this high-risk industrial safety incident often leads to accidents due to misjudgment, the operator of the mains supply line (Taiwan Electric Power Company) can prevent the electric breaker from jumping out of the circuit breaker due to the sudden voltage drop. The flow is saturated and slow, and the institution is required to install the protection system according to the regulations, and then the power supply is promised. The main provisions are: when the secondary side power supply of the comparator is used, it should be supplemented by a capacitive tripping device (CTD) or a capacitor tripping device and then connected to the uninterruptible power system (UPS), and electronically or The Capacitor Trip Unit (CTD) used in digital power units shall not be used for circuit breakers or other equipment. This is ideal, but accidents often come from ideal conditions. In practice, the UPS will almost always fail after one or two years. However, the business unit will not notice that when there is a short circuit accident, it is found that the high voltage circuit breaker (HVCB) will not trip, and it is found that the uninterruptible power system (UPS) cannot supply the working power supply to the protection relay (Relay). But it is too late.
但觀察一般的電容跳脫裝置，放置在盤體內並不明顯。也沒有輸入電源的指示、輸出電壓明確的指示、與相關狀態的指示。且在盤體內外無法共用。沒有明確的指示電壓值是否過低，且沒有外接輸出接點指 示、警報或者連接至中央控制室中，內部沒有自動偵測功能，當電容因時間衰減，會造成電容跳脫裝置失能，並且若是沒有警示、指示及警示接點的裝置功能，會造成高壓盤於系統故障時，跳脫迴路沒有工作電源，而無法隔離事故點的嚴重情形。 However, observing the general capacitive tripping device is not obvious in the disc body. There is also no indication of the input power, an explicit indication of the output voltage, and an indication of the relevant status. It cannot be shared inside and outside the disk. There is no clear indication that the voltage value is too low, and there is no external output contact finger The display, alarm or connection to the central control room, there is no automatic detection function inside, when the capacitance is attenuated due to time, the capacitance trip device will be disabled, and if there is no device function of warning, indication and warning contact, it will cause high voltage. When the system is faulty, the tripping loop does not have a working power supply, and it is impossible to isolate the serious situation of the accident point.
在習有的電容跳脫裝置經改善特性以後，其功能上已經有進步許多，但是再好的產品都有故障的時候，所以接下來就有必須要具備AC交流電源支援以及輸出DC直流的電源支援，以利電容跳脫裝置能夠有效地提供高壓盤跳脫迴路的工作電源，提昇系統的安全性以及穩定性。 After the improved capacitance tripping device has improved its characteristics, its function has been improved a lot, but even the best products have faults, so there must be AC power supply support and DC DC power supply. Support, to facilitate the capacitor trip device can effectively provide the working power of the high voltage disk trip circuit, improve the safety and stability of the system.
在實際的配電盤中，其中不乏是老舊的系統，所以無法一次就可以在盤面上做更換，所以製作一只盤面與固定兩用型的功能，就是必須要克服的因素之一，以利實際現場的需求。 In the actual switchboard, there is no shortage of old systems, so it is impossible to replace them on the disk at one time. Therefore, the function of making a disk surface and fixed dual-use type is one of the factors that must be overcome to facilitate the actual operation. On-site needs.
本發明申請人對於高壓配電系統中，其高壓配電盤中的跳脫迴路工作電源改善方示，已經有數個方案提出並申請專利，尤其在電容跳脫裝置CTD的改良方面，從在有載之下可測試，有電錶顯示其電壓值，到盤面式可以有效防止因開啟高壓配電盤而可能引起的工安事故預防，有電壓比較電路及警報電路的電容跳脫裝置可以解決電容器會因時間而衰減的問題，有時間電路與電壓比較電路的組合，可以每日或設定時間以模擬事故發生時，其跳脫迴路工作電源是否足以推動其負載設備以隔離事故，進一步有自動電源轉換電路的CTD，以防止電容跳脫裝置故障時，外部電源有交流及直流電源的支援，以及可以解決電壓以及電容量和通訊的問題，以上的解決方案是目前市場的產品。 The applicant of the present invention has proposed and patented several schemes for the improvement of the working power of the tripping loop in the high-voltage power distribution system in the high-voltage power distribution system, especially in the improvement of the CTD of the capacitor tripping device, from under load It can be tested. It has a voltage meter to display its voltage value. The disk surface type can effectively prevent the accidents caused by the opening of the high-voltage switchboard. The capacitor tripping device with voltage comparison circuit and alarm circuit can solve the problem that the capacitor will decay due to time. The problem is that there is a combination of time circuit and voltage comparison circuit, which can be used daily or set time to simulate the occurrence of an accident. Is the tripping circuit working power supply enough to push its load device to isolate the accident, and further have the CTD of the automatic power conversion circuit to When the capacitor trip device is prevented from malfunctioning, the external power supply has the support of AC and DC power, and the voltage, capacity and communication problems can be solved. The above solution is the current market product.
以上的產品使用在新建工程時，於新設備規劃時，一般而言 問題都可以獲得解決，但是在實際目前已在運轉送電中的高壓盤，若欲於停電作換修時，則會遇到許多特殊的狀況，以致在先前的技術上無法克服的問題與困難，尤其尺寸的問題、配線的問題、容量的問題……等。 The above products are used in new construction, when planning new equipment, in general The problem can be solved, but in the actual high-voltage disk that is currently running the power transmission, if you want to change the power for repair, you will encounter many special conditions, so that the problems and difficulties that could not be overcome in the previous technology, Especially the size problem, the wiring problem, the capacity problem, etc.
在現場配電盤中第一個面臨的問題是尺寸的問題，由於以往配電盤製作廠家，並沒有意識到其高壓盤中跳脫迴路工作電源的重要性。 所以在大部分的狀況下，是在盤內中只有一只斷路器使用的CTD，而保護電驛的工作電源往往由不斷電系統(UPS)所提供，導致欲更換為兩台CTD時，會有空間不足的問題，以及重新配線的問題，而非兩台CTD並用可以解決該空間位置不足的現場狀況。 The first problem faced in the field switchboard was the size problem. Because of the previous switchboard manufacturers, they were not aware of the importance of tripping the loop power supply in their high voltage discs. Therefore, in most cases, there is a CTD used by only one circuit breaker in the disk, and the working power of the protection power is often provided by the UPS, resulting in the replacement of two CTDs. There will be problems with insufficient space and rewiring problems, instead of using two CTDs to solve the situation of the site where the space is insufficient.
在現場配電盤中欲換修舊有電容跳脫裝置時，會遇到的第二個問題，是在舊有設備器材中，舊有的電容跳脫裝置有半波整流型、有全波整流型，以及有因為廠家不同時，其輸入點與輸出點的接續配置不同而不同，以及內部電路結構問題，當全波整流型欲接續至舊有的器材中時，可能發生短路的狀況，如此在實際的實例上常常發生，短路情況亦常常時有所聞，是必須克服的一個問題。 The second problem encountered when replacing the old capacitor tripping device in the field switchboard is that in the old equipment, the old capacitor tripping device has a half-wave rectification type and a full-wave rectification type. And because the manufacturer does not have different connection configurations of the input point and the output point, and the internal circuit structure problem, when the full-wave rectification type is to be connected to the old equipment, a short circuit may occur, so Actual examples often occur, and short-circuit conditions are often heard, which is a problem that must be overcome.
再者高壓斷路器配電盤上，有許多的感應元件、感測元件、顯示元件、操作元件、監視元件……等不一樣，並且主斷路器CB與主配線控制盤中，其因為控制方式不同，以及因系統之需求，所以有控制的配線裝置一般都會有配電控制端子台，藉以連結其主盤體與主控制面盤迴路，尤其是主盤與控制盤中間會有許多的連結端子，由於與其他控制系統連結，會造成當單純方式更換電容跳脫裝置時會有不作動或者短路的問題產生。 Furthermore, there are many sensing elements, sensing elements, display elements, operating elements, monitoring elements, etc. on the switchboard of the high-voltage circuit breaker, and the main circuit breaker CB and the main wiring control panel are controlled by different methods. And due to the needs of the system, the controlled wiring device generally has a power distribution control terminal block, so as to connect the main disk body and the main control surface circuit, especially the main disk and the control disk have many connection terminals, due to The connection of other control systems will cause problems such as no operation or short circuit when the capacitor jumper is replaced by a simple method.
實際現場維修作業中，許多的高壓系統的檢測維護大部分是委託機電維修公司做維護工作，並且委任方式大部分是公開招標的方式進行，在一段時限委任於某一得標之機電顧問維修公司做維修保養工作，每一家機電顧問公司對於系統的保護裝置以及控制方式，其觀念上不盡相同，於是當高壓系統在停電維修時，會改變其中某些器材元件，及至改變其控制方式以及操作方法……等，如此因素會增加其維修時，對於電容跳脫裝置的配線接續更換時的複雜度。 In the actual on-site maintenance work, most of the high-pressure system inspection and maintenance is commissioned by the mechanical and electrical maintenance company to do maintenance work, and most of the appointment methods are conducted by means of open tendering, and are appointed to a certain qualified mechanical and electrical consultant maintenance company within a certain period of time. For maintenance work, each mechanical and electrical consultant company has different concepts about the protection devices and control methods of the system. Therefore, when the high-voltage system is in power failure maintenance, some of the equipment components will be changed, and the control mode and operation will be changed. Method...etc., such factors increase the complexity of the replacement of the wiring of the capacitor tripping device during maintenance.
更有甚者，在實際配電盤上，在控制盤上的原電路圖資料袋也不見，或者圖面與實際器具擺置裝配不一致，甚至電容跳脫裝置不見了，以致找不到原本控制的線路，導致電源在何處都必須仰賴經驗、目測以及電錶來確認其電源的狀況，更增加其換修的困難度，並影響系統的穩定性及安全性。 What's more, on the actual switchboard, the original circuit diagram kit on the control panel is also missing, or the drawing is inconsistent with the actual appliance placement assembly, and even the capacitor trip device is missing, so that the originally controlled line cannot be found. The location of the power supply must rely on experience, visual inspection and electricity meter to confirm the status of its power supply, increase the difficulty of its replacement, and affect the stability and safety of the system.
在許多實際情況是水電工程公司不了解其高壓盤中其電容跳脫裝置CTD的輸出直流電源，是提供當高壓配電系統發生故障時所需的跳脫迴路工作電源，意外狀況是在不知該電源為專用電源的狀況下，再續接一些負載，會導致故障發生時，該電容跳脫裝置無法作動的狀況，並且實際上會造成控制線路的配置複雜化，也使得欲在此現場維修欲更換電容跳脫裝置時的困難度。 In many practical situations, hydropower engineering companies do not understand the output DC power supply of its capacitor tripping device CTD in its high-voltage disk. It is the tripping circuit power supply required when the high-voltage power distribution system fails. The unexpected situation is that the power supply is unknown. In the case of a dedicated power supply, if some load is continuously connected, the capacitor tripping device cannot be activated when the fault occurs, and the configuration of the control circuit is actually complicated, and the repair is to be replaced at this site. The difficulty of the capacitor tripping device.
還有在現場高壓盤中，一種非常常見的狀況是以一台簡易型電容跳脫裝置，以當濾波器的方式原理功能，供應整個高壓系統中，所有的跳脫迴路工作電源，如此對於現場換修該電容跳脫裝置時，則必須考慮其系統中，控制電源的正確性，以及電源的來源，並且要避免該電容跳脫 裝置CTD串接於不斷電系統UPS，以防止UPS內部電池因時間的關係而造成失能的問題，若原本的配線方式為UPS串接電容跳脫裝置，也必須改變配線方式以符合台電法規的要求。 There is also a very common situation in the field high-voltage disk, which is a simple capacitor tripping device, which functions as a filter principle, supplies all the tripping circuit working power in the whole high-voltage system, so for the scene When replacing the capacitor trip device, you must consider the correctness of the control power supply in the system, as well as the source of the power supply, and avoid the capacitor tripping. The CTD of the device is connected in series with the UPS of the uninterruptible power system to prevent the internal battery of the UPS from being disabled due to the time. If the original wiring method is the UPS serial capacitor tripping device, the wiring mode must also be changed to comply with the Taipower regulations. Requirements.
綜上所述，為欲換修電容跳脫裝置CTD，在現場中所面臨實際的狀況，以往並無法有效率的來解決該問題，於是從現場中的狀況分析研究，一種具有備用電源的電容跳脫裝置可以解決上述的問題，同時可以解決尺寸大小的問題以及正確配線的問題。 In summary, in order to replace the CTD of the capacitor tripping device, the actual situation faced in the field has not been able to solve the problem efficiently in the past, so the situation analysis in the field, a capacitor with a backup power supply The trip device can solve the above problems, and can solve the size problem and the problem of proper wiring.
一種具有備用電源的電容跳脫裝置，可以有效解決市場上因為尺寸過大空間放不下的問題，現場配線的問題因為控制方式及配置方法連結方式不同的問題，在配電盤中控制盤中上下位置以及端子台接續的問題，乃至於器材元件本身的問題，在實際配電盤中必須尋找配線電源的問題，以及人為問題，舉凡機電顧問在維護保養中所衍生的問題，甚至年久失修時配電盤中找不到欲更換的器具、容量不足的問題……等狀況，尤其是應用在實際現場換修時，可藉由本裝置可以有效率的解決上述的問題。 A capacitor tripping device with a backup power supply can effectively solve the problem that the size of the space cannot be put down in the market. The problem of the field wiring is because of the different control modes and the connection methods of the configuration methods, and the upper and lower positions and terminals in the control panel in the switchboard The problem of the connection, and even the problems of the components of the equipment itself, the problem of wiring power supply must be found in the actual switchboard, as well as the human problem, the problems arising from the maintenance of the mechanical and electrical consultants, even in the switchboard when the maintenance is in disrepair The device to be replaced, the problem of insufficient capacity, etc., especially when applied to actual field repair, the above problem can be solved efficiently by the device.

In the case of 虞, the use of more precise and reliable equipment components, the size is reduced to half of the original, so that the capacitor trip device can be easily replaced in the actual switchboard in the field, without being limited by the size of the problem, resulting in configuration Insufficient location can not be repaired.
