低壓斷路器電動操作控制改良裝置 Improvement device for electric operation control of low-voltage circuit breaker

本創作一種低壓斷路器電動操作控制改良裝置，可以改善習有斷路器於電力迴路中當火災發生時，該斷路器無法強制於閉合位置以利供電正常給消防系統，防止消防設備因沒有電源而失能，造成事故發生，以確保用電安全。 This invention creates an improved device for electric operation control of low-voltage circuit breakers, which can improve the conventional circuit breaker in the power circuit. When a fire occurs, the circuit breaker cannot be forced to the closed position to facilitate the normal power supply to the fire-fighting system and prevent fire-fighting equipment from being damaged due to no power supply. Disability, causing accidents, to ensure the safety of electricity.

目前市場上電力迴路系統在低電供電情況下其低電配電器具保護開關例如模殼式斷路器、低壓空氣式斷路器，一般皆配置在低壓配電系統上，以提供低電配電系統對於線路上短路保護以及用電設備故障保護，而該斷路器本身一般而言並沒有提供其設備或環境發生火災時，提供自我偵測功能，並確保該斷路器強制閉合通電，會造成火災或意外事故時，電力系統供電無法提供電力給消防設備，造成工安事故。 At present, in the case of low power supply in the power circuit system on the market, the low-power distribution equipment protection switches, such as mold case circuit breakers and low-voltage air circuit breakers, are generally configured on the low-voltage power distribution system to provide low-power power distribution systems for the lines. Short-circuit protection and fault protection of electrical equipment, and the circuit breaker itself generally does not provide its equipment or environment. When a fire occurs, it provides a self-detection function and ensures that the circuit breaker is forced to close and energize, which may cause fire or accidents. , The power supply of the power system cannot provide power to the fire-fighting equipment, resulting in industrial safety accidents.

若電力迴路，因為其消防設備於檢修時，將斷路器斷電維修，或設備安裝完畢於完工後忘記將該斷路器閉合，造成當火災事故發生時，該消防設備因為斷路器沒有作動閉合，沒有提供電源給消防設備或消防泵、撒水泵、排煙機、緊急電梯...而造成工安事故，在目前社會新聞也常常報導，是一個非常嚴肅且必須改善的問題，並且一般的低壓斷路器在電力迴路發生故障時會閉鎖其低壓斷路器，所以當在火警發生時，應改以消防用電為第一優先，而故障發生時的閉鎖動作為次要優先動作順序。 If the power circuit, because the fire-fighting equipment is overhauled, the circuit breaker is turned off for maintenance, or the circuit breaker is forgotten to be closed after the equipment is installed, so that when a fire accident occurs, the fire-fighting equipment is closed because the circuit breaker does not operate. Failure to provide power to firefighting equipment or fire pumps, water sprinkler pumps, smoke exhaust machines, emergency elevators...causing industrial safety accidents is often reported in the current social news The report is a very serious problem that must be improved, and the general low-voltage circuit breaker will lock its low-voltage circuit breaker when the power circuit fails. The blocking action when a fault occurs is the secondary priority action sequence.

依據用戶用電設備裝置規則當運轉性的電動機依法第155條隔離設備之位置裝置要求，該運轉性的電動機設備，於維修時應在啟斷位置可上鎖，又依據勞動部的勞檢要求，設備維修更換時必須斷電，斷路器上鎖在啟斷位置或斷路器的負載側將電線拆下隔離以維護安全，再依消防法的要求，對於消防設施應定期維護保養檢修以確保消防設備之功能，在實際的狀況下，因疏忽忘記將斷路器重新閉合通電的情況時有發生，是必須改善的問題。 According to the user's electrical equipment installation rules, when the operating motor is in accordance with the position installation requirements of Article 155 of the isolation equipment, the operating motor equipment should be locked in the on-off position during maintenance, and according to the labor inspection requirements of the Ministry of Labor , When the equipment is repaired and replaced, the power must be cut off, the circuit breaker is locked in the on-off position or the load side of the circuit breaker is removed to isolate the wires to maintain safety, and then according to the requirements of the fire protection law, the fire protection facilities should be regularly maintained and repaired to ensure fire protection The function of the equipment, in the actual situation, the situation of forgetting to re-close the circuit breaker and power on due to negligence happens from time to time, which is a problem that must be improved.

一般常見施工誤判，誤以為當電力系統有供電，並且消防設備若是維修狀態良好，則當發生火災時該消防設備一定有作用，此時若是沒有一穩定的電源供應，此時仍會發生意外，尤其是在供給電源的低壓斷路器其在電力系統迴路中，若因過載或故障電流過大而跳脫，會造成沒有電源供應的狀況，因此該斷路器除了故障必須能隔離事故將斷路器跳脫斷電外，當火災發生時必須能強制閉合該斷路器以利供電給消防設備，是非常重要且必須改善的問題。 Generally, construction misjudgments are common, mistakenly thinking that when the power system has power supply and the fire-fighting equipment is in good repair, the fire-fighting equipment must be effective in the event of a fire. If there is no stable power supply at this time, accidents will still occur at this time. Especially in the low-voltage circuit breaker that supplies power, if it trips due to overload or excessive fault current in the power system circuit, it will cause no power supply. Therefore, the circuit breaker must be able to isolate the accident and trip the circuit breaker except for faults. In addition to power failure, when a fire occurs, the circuit breaker must be closed forcibly so as to supply power to the fire-fighting equipment, which is a very important problem that must be improved.

一般電力系統在規劃中，對於消防設備電力供給的電力迴路上，一般由低壓斷路器做為隔離設備，一般而言以使用低壓空氣斷路器或低壓模殼式開關為主，該低壓開關，於火災發生時，該斷路器無法自行強制閉合通電是其缺失，並且在許多的情況下，其火災發生後的信息並沒有與該供電的斷路器連結，以上的問題是必須解決，以防止事故的再發生。 In the general power system planning, low-voltage circuit breakers are generally used as isolation devices for the power supply circuit of fire-fighting equipment. Generally speaking, low-voltage air circuit breakers or low-voltage molded switches are mainly used. When a fire occurs, the circuit breaker cannot be forced to close and energize by itself, and in many cases, the information after the fire is not connected to the circuit breaker for power supply. The above problems must be solved to prevent accidents. Happen again.

該火警作動單元電性連結一火警信號、該外置式連動操作把手電動馬達，依該火警信號信息作動驅動該外置式連動操作把手電動馬達作動或不作動，當該火警作動單元作動時，該低壓斷路器電動操作控制改良裝置強制使該低壓斷路器在閉合位置，並限制該外部指令單元作動； The fire alarm actuating unit is electrically connected with a fire alarm signal and the electric motor of the external interlocking operation handle, and drives the electric motor of the external interlocking operation handle to actuate or not actuate according to the fire alarm signal information, When the fire alarm actuating unit is actuated, the low-voltage circuit breaker electric operation control improvement device forces the low-voltage circuit breaker to be in the closed position and restricts the external command unit from actuating;

其中該低壓斷路器電動操作控制改良裝置，設置有該控制電源單元提供適當電源，並設置該外置式連動操作把手電動馬達、該外部指令單元，當火災事故發生時，該火警作動單元作動，驅動該外置式連動操作把手電動馬達使該低壓斷路器在閉合狀態提供電源，當該火警作動單元不作動時，該低壓斷路器電動操作控制改良裝置可依該外部指令單元作動啟斷或閉合或跳脫的功能。 Among them, the low-voltage circuit breaker electric operation control improvement device is provided with the control power supply unit to provide appropriate power supply, and is provided with the external interlocking operation handle electric motor and the external command unit. When a fire accident occurs, the fire alarm actuation unit activates and drives The external interlocking operation handle electric motor enables the low-voltage circuit breaker to provide power in the closed state. When the fire alarm actuating unit does not operate, the low-voltage circuit breaker electric operation control improvement device can be activated or closed or tripped according to the external command unit. off function.
