Description
本創作係關於一種斷路器，特別是關於一種漏電斷路器之引弧結構。 This creation relates to a circuit breaker, especially an arc striking structure of an earth leakage circuit breaker.
漏電斷路器是一種保護電器安全的重要裝置，主要是能短路保護和防止嚴重超載，當漏電斷路器偵測到短路、漏電或嚴重超載等問題時，斷路器可以立即跳脫，具有防止線路過載或短路保護的功能，以保護使用者與用電設備的安全。 The leakage circuit breaker is an important device to protect the safety of electrical appliances. It is mainly used for short-circuit protection and preventing severe overload. When the leakage circuit breaker detects problems such as short circuit, leakage or serious overload, the circuit breaker can immediately trip, which can prevent the line from overloading. or short-circuit protection function to protect the safety of users and electrical equipment.
習知的單相二極漏電斷路器，其中N極斷路器由於空間不足夠及成本考量等原因，因此無法裝設消弧室，若漏電斷路器的短路故障電流通過時，可動子的接點與接觸子的接點之間會產生電動斥力作用，使可動子的接點與接觸子的接點從導通變成跳脫的狀態，形成斷路以保護電器，此時電流過大使漏電斷路器短路，漏電斷路器中會產生電弧，由於N極斷路器中並沒有消弧室，因此使電弧可能對N極斷路器中的組件造成絕緣不良，甚至導致漏電斷路器受到損害。 In the conventional single-phase two-pole earth leakage circuit breaker, the N-pole circuit breaker cannot be equipped with an arc suppression chamber due to insufficient space and cost considerations. There will be an electric repulsion effect between the contact point of the contactor and the contact point of the contactor, so that the contact point of the mover and the contactor of the contactor will change from conduction to tripping state, forming an open circuit to protect the electrical appliance. An arc will be generated in the residual current circuit breaker. Since there is no arc extinguishing chamber in the N-pole circuit breaker, the arc may cause poor insulation of the components in the N-pole circuit breaker, or even damage the residual current circuit breaker.
