<strong>繼電器</strong>的符號表示方法（一） </p> <p> 繼電器線圈在電路中用一個長方框符號表示，如果繼電器有兩個線圈，就畫兩個并列的長方框。同時在長方框內(nèi)或長方框旁標(biāo)上繼電器的文字符號“J”。繼電器的觸點(diǎn)有兩種表示方法：一種是把它們直接畫在長方框一側(cè)，這種表示法較為直觀，監(jiān)測繼電器經(jīng)銷商。另一種是按照電路連接的需要，監(jiān)測繼電器經(jīng)銷商，把各個觸點(diǎn)分別畫到各自的控制電路中，監(jiān)測繼電器經(jīng)銷商，通常在同一繼電器的觸點(diǎn)與線圈旁分別標(biāo)注上相同的文字符號，并將觸點(diǎn)組編上號碼，以示區(qū)別。繼電器的觸點(diǎn)一共有有3種基本形式。

1、環(huán)境對繼電器可靠性的影響：繼電器工作在GB和SF下的平均故障間隔時間比較高，達(dá)到820000h，而在NU環(huán)境下，*60000h。 </p> <p> 2、質(zhì)量等級對繼電器可靠性的影響：當(dāng)選用A1質(zhì)量等級的繼電器時，平均故障間隔時間可達(dá)3660000h，而選用C等級的繼電器平均故障間隔時間為110000，其間相差33倍，可見繼電器的質(zhì)量等級對其可靠性能的影響非常大。 </p> <p> 3、觸點(diǎn)形式對繼電器可靠性的影響：繼電器的觸點(diǎn)形式也會對其可靠性產(chǎn)生影響，單擲型繼電器的可靠性都高于相同刀數(shù)的雙擲型繼電器，同時隨刀數(shù)的增加可靠性逐漸降低，單刀單擲繼電器的平均故障間隔時間是四刀雙擲繼電器的5.5倍。 </p> <p> 4、結(jié)構(gòu)類型對繼電器可靠性的影響：繼電器結(jié)構(gòu)類型共有24種，不同類型均對其可靠性產(chǎn)生影響。 </p> <p> <br /> </p> <p> <br /> 監(jiān)測繼電器經(jīng)銷商速度繼電器的選型方法有哪些？</p><div style="width:100%;text-align: center;"><img

<p> <br /> </p> <p> <strong>繼電器</strong>測試（一） </p> <p> ①測觸點(diǎn)電阻:用萬用表的電阻擋，測量常閉觸點(diǎn)與動點(diǎn)電阻，其阻值應(yīng)為0；而常開觸點(diǎn)與動點(diǎn)的阻值就為無窮大。由此可以區(qū)別出那個是常閉觸點(diǎn)，那個是常開觸點(diǎn)。 </p> <p> ②測線圈電阻:可用萬用表R×10擋測量繼電器線圈的阻值，從而判斷該線圈是否存在著開路現(xiàn)象。 </p> <p> ③測量吸合電壓和吸合電流：用可調(diào)穩(wěn)壓電源和電流表，給繼電器輸入一組電壓，且在供電回路中串入電流表進(jìn)行監(jiān)測。慢慢調(diào)高電源電壓，聽到繼電器吸合的聲音時，記錄吸合電壓和吸合電流。為求準(zhǔn)確，可以嘗試多次求平均值。

時間繼電器在控制電路中用于時間的控制。時間繼電器是一種使用在較低的電壓或較小電流的電路上，用來接通或切斷較高電壓、較大電流的電路的電氣元件。同時，時間繼電器也是一種利用電磁原理或機(jī)械原理實(shí)現(xiàn)延時控制的控制電器。其種類很多，按其動作原理可分為電磁式、空氣阻尼式、電動式和電子式等，按延時方式可分為通電延時型和斷電延時型?？諝庾枘崾綍r間繼電器是利用空氣阻尼原理獲得延時的，它由電磁機(jī)構(gòu)、延時機(jī)構(gòu)和觸頭系統(tǒng)3部分組成。電磁機(jī)構(gòu)為直動式雙E型鐵心，觸頭系統(tǒng)借用I-X5型微動開關(guān)，延時機(jī)構(gòu)采用氣囊式阻尼器。

當(dāng)執(zhí)行繼電器的繞組（感性負(fù)載）被接通和斷開時。線圈中會產(chǎn)生一連串上升速度快，頻率和幅度都相當(dāng)高的尖峰脈沖電磁振蕩輻射，對直流繼電器繞組通常采用以下方法來減少干擾： </p> <p> 在線圈兩端反并二極管或RC器件，如控制觸點(diǎn)對交流感性負(fù)載的控制，也可考慮在觸點(diǎn)并接RC器件，從而能對觸點(diǎn)在通斷時產(chǎn)生的干擾進(jìn)行有效的吸收。 </p> <p> 屏蔽 </p> <p> 屏蔽能有效地***通過空間傳播的電磁干擾，一則可限制內(nèi)部產(chǎn)生的電磁能輻射出去；二則可防止外來輻射進(jìn)入，在對內(nèi)部電子線路采用整體屏蔽措施，也可對內(nèi)部信號線采用屏蔽線，增強(qiáng)其抗干擾能力。 </p> <p> <br /> </p> <p> <br /> 電磁式繼電器的接線方法有哪些？監(jiān)測繼電器經(jīng)銷商</p><p
