我們做微機(jī)保護(hù)裝置的企業(yè)都知道、微機(jī)保護(hù)裝置是高壓控制系統(tǒng)的重要部分,一般微機(jī)保護(hù)項(xiàng)目的開(kāi)展都需要檢測(cè)報(bào)告，不同項(xiàng)目，有的需要開(kāi)普檢測(cè)報(bào)告，有的要南網(wǎng)入網(wǎng)報(bào)告。下面我們談微機(jī)保護(hù)裝置相關(guān)資質(zhì)到底有什么作用 </p> <p> 1、開(kāi)普檢驗(yàn)報(bào)告。 </p> <p> 開(kāi)普檢測(cè)報(bào)告是由國(guó)家繼電保護(hù)檢測(cè)中心經(jīng)過(guò)檢測(cè)合格后頒布的一種資質(zhì)證書，它是反應(yīng)一個(gè)廠家產(chǎn)品的是否合格的**常見(jiàn)相發(fā)有效的一種資質(zhì)證書，這款資質(zhì)是按型號(hào)命名檢測(cè)的、一般的，不同型號(hào)的產(chǎn)品，都需要辦理檢測(cè)報(bào)告，開(kāi)普檢測(cè)報(bào)告，是體現(xiàn)一個(gè)廠家是否合格的重要標(biāo)志，也是體現(xiàn)一個(gè)廠家重要的技術(shù)實(shí)力和綜合實(shí)力的重要瓢標(biāo)志， </p> <p> 辦理流程：申請(qǐng)檢測(cè)，手費(fèi)費(fèi)30000，然后把產(chǎn)品拿到河南許昌繼電保護(hù)進(jìn)行檢測(cè)，檢測(cè)其產(chǎn)品抗干擾功能、產(chǎn)品保護(hù)功能，產(chǎn)品通訊功能、產(chǎn)品做工是否符合國(guó)家電力部分的要求，如果上述所有功能都能達(dá)到國(guó)家規(guī)定的要求，就能獲得開(kāi)普試驗(yàn)檢測(cè)報(bào)告資質(zhì)證書。 </p> <p> 2、入網(wǎng)資質(zhì)。 </p> <p> 入網(wǎng)資質(zhì)是國(guó)家電網(wǎng)部分經(jīng)中化人民共合同智能電網(wǎng)的使用標(biāo)準(zhǔn)經(jīng)檢檢合極頒布的一種產(chǎn)品檢驗(yàn)資質(zhì)、入網(wǎng)資質(zhì)主要分為南網(wǎng)入網(wǎng)報(bào)告和華北電網(wǎng)入網(wǎng)報(bào)告，從業(yè)電力設(shè)備制造的企業(yè)也只有有這個(gè)國(guó)家電網(wǎng)入網(wǎng)資質(zhì)的企業(yè)才有權(quán)利做國(guó)家智能電網(wǎng)相關(guān)的項(xiàng)目。

由微型計(jì)算機(jī)或單片機(jī)構(gòu)成的保護(hù)稱為微機(jī)保護(hù)。微機(jī)保護(hù)與傳統(tǒng)繼電保護(hù)相比就在于微機(jī)保護(hù)不僅有實(shí)現(xiàn)繼電保護(hù)功能的硬件電路,而且還具有保護(hù)和管理功能的軟件程序,適應(yīng)性強(qiáng);而常規(guī)繼電保護(hù)則只有硬件電路。 </p> <p> <br /> </p> <p> <br /> </p> <p> 微機(jī)保護(hù)與傳統(tǒng)保護(hù)相比有哪些優(yōu)點(diǎn)? </p> <p> <br /> </p> <p> (1)程序具有自適應(yīng)性,可按系統(tǒng)運(yùn)行狀態(tài)自動(dòng)改變整定值和 </p> <p> <br /> </p> <p> 特性。 </p> <p> <br /> </p> <p> (2)有可存取的存儲(chǔ)器。 </p> <p> <br /> </p> <p> (3)在現(xiàn)場(chǎng)可靈活地改變繼電器的特性。 </p> <p> <br /> </p> <p> (4)可以使保護(hù)性能得到更大的改進(jìn)。 </p> <p> <br /> </p> <p> (5)有自檢能力。 </p> <p> <br /> </p> <p> (6)有利于故障后分析。 </p> <p> <br /> </p> <p> (7)可與計(jì)算機(jī)交換信息,實(shí)現(xiàn)網(wǎng)絡(luò)管理。 </p> <p> <br /> </p> <p> (8)可增加硬件的功能。 </p> <p> <br /> </p> <p> (9)可在低功率傳變機(jī)構(gòu)內(nèi)工作。 </p> <p>
