開關電源有兩種：一種是直流開關電源；另一種是交流開關電源。

過流繼電器的動作原理是復合式的,它由感應式和電磁式的兩個元件組成,兩個元件公用一個線圈。電壓互感器（potential transformer 簡稱pt，voltage transformer也簡稱vt）和變壓器類似，是用來變換線路上的電壓的儀器。電壓表是測量電壓的一種儀器，常用電壓表——伏特表的符號為“v”。

繼電器通常應用于自動化的控制電路中，它實際上是用小電流去控制大電流運作的一種“自動開關”。故在電路中起著自動調節(jié)、安全保護、轉換電路等作用。

功率因數表是指單相交流電路或電壓對稱負載平衡的三相交流電路中測量功率因數的儀表。常見的功率因數表有電動系、鐵磁電動系、電磁系和變換器式等幾種。

數字儀表以數字的形式顯示被測量，讀數直觀。 一般包括：用標度盤和指針指示電量，用電磁力為基礎的電括測量線路，模數轉換和數字顯示三部份。

開關電源是利用現代電力電子技術，控制開關管開通和關斷的時間比率，維持穩(wěn)定輸出電壓的一種電源，開關電源一般由脈沖寬度調制（pwm）控制ic和mosfet構成。隨著電力電子技術的發(fā)展和-，使得開關電源技術也在不斷地-。電流互感器是由閉合的鐵心和繞組組成。它的一次側繞組匝數很少，串在需要測量的電流的線路中。當主設備或輸配電系統出現過負荷及短路故障時，該繼電器能按預定的時限-動作或發(fā)出信號，切除故障部分，-主設備及輸配電系統的安全。頻率表是指測量頻率的機械式指示電表。頻率表種類很多，有電動系、鐵磁電動系和屬于整流式的變換器式頻率表等。生產現場用來監(jiān)測頻率用的安裝式頻率表，大多采用鐵磁電動系電表的測量機構。

氣動閥采購時只明確規(guī)格、類別、工壓就滿足采購要求的作法，在當前市場經濟環(huán)境里是不完善的因為氣動閥制造廠家為了產品的競爭，各自均在氣動閥統一設計的構思下，進行不同的-，形成了各自的企業(yè)標準及產品個性。因此在氣動閥采購時較詳盡的提出技術要求，與廠家協調取得共識，作為氣動閥采購合同的附件是十分-的。

電磁閥有很多種，不同的電磁閥在控制系統的不同位置發(fā)揮作用，常用的是單向閥、安全閥、方向控制閥、速度調節(jié)閥等。氣動球閥是球閥配上氣動執(zhí)行器。氣動執(zhí)行器的執(zhí)行速度相對較快，-的開關速度0.05秒/次，所以通常也叫氣動快速切斷球閥。
