              為大家講解為什么選用固態繼電器?

              ABB微型斷路器與傳統斷路器相比,是一種沒有機械運動,不含運動零件的電器元件,但它同樣有著傳統斷路器的基礎功能。固態斷路器是一種全部由固態電子元件組成的無觸點開關元件,他利用電子元器件的點,磁和光特性來完成輸入與輸出的可靠隔離,利用大功率三極管,功率場效應管,單項可控硅和雙向可控硅等器件的開關特性,來達到無觸點,無火花地接通和斷開被控電路

              Compared with the traditional circuit breaker, abb miniature circuit breaker is an electrical component without mechanical movement and moving parts, but it also has the basic functions of the traditional circuit breaker. Solid state circuit breaker is a contactless switching element composed of all solid-state electronic components. It uses the point, magnetic and optical characteristics of electronic components to complete the reliable isolation of input and output, and uses the switching characteristics of high-power triode, power field effect transistor, single thyristor and bidirectional thyristor to connect and disconnect the controlled circuit without contact and spark
              為什么選用固態斷路器
              Why solid state circuit breaker
              (1)壽命長,性能穩定:固態斷路器由于沒有機械零部件,有固體器件完成觸點功能,由于沒有運動的零部件,因此能在高沖擊,振動的環境下工作,由于組成固態斷路器的元器件的固有特性,決定了固態斷路器的壽命長,可靠性高。
              (1) Long service life and stable performance: the solid-state circuit breaker has no mechanical parts and solid devices to complete the contact function. Because there are no moving parts, it can work in the environment of high impact and vibration. Due to the inherent characteristics of the components constituting the solid-state circuit breaker, the solid-state circuit breaker has long service life and high reliability.
              ABB微型斷路器
              (2)靈敏度高,控制功率小,電磁兼容性好:固態斷路器的輸入電壓范圍較寬,驅動功率低,可與大多數邏輯集成電路兼容不需加緩沖器或驅動器。
              (2) High sensitivity, low control power and good electromagnetic compatibility: the input voltage range of solid-state circuit breaker is wide and the driving power is low. It can be compatible with most logic integrated circuits without adding buffer or driver.
              固態斷路器的規格選擇
              Specification selection of solid state circuit breaker
              (1)單相 直流控交流 交流控交流 直流控直流 10A-120A
              (1) Single phase DC controlled AC controlled DC 10a-120a
              (2)三相 直流控交流 交流控交流 10-120A
              (2) Three phase DC controlled AC 10-120a
              固態斷路器通過大電流時,一般都會發熱,然后固態本身的散熱沒有那么完善,長時間的發熱,會導致固態斷路器的損壞,所以這個時候散熱器就起到了一個很大的作用,散熱器的選擇也分很多種,一般根據固態斷路器的體積不同也選擇適應的散熱器。
              When the solid-state circuit breaker passes through a large current, it will generally generate heat, and then the heat dissipation of the solid-state circuit breaker itself is not so perfect. Long-term heating will lead to the damage of the solid-state circuit breaker. Therefore, at this time, the radiator plays a great role. There are many kinds of radiator choices. Generally, the appropriate radiator is also selected according to the volume of the solid-state circuit breaker.
