【摘要】：在航天軍工產(chǎn)品中,儀器設(shè)備、線纜線束,作為整個(gè)系統(tǒng)的一部分,起著決定性作用。儀器和線纜的質(zhì)量直接決定了產(chǎn)品的質(zhì)量,其檢測(cè)作為保證整體質(zhì)量的關(guān)鍵環(huán)節(jié),已受到航天軍工制造各企業(yè)的高度重視。產(chǎn)品的絕緣電阻特性及耐壓性能是關(guān)系到產(chǎn)品質(zhì)量?jī)?yōu)劣的重要因素,目前市場(chǎng)上存在的要么是價(jià)格高昂的自動(dòng)化測(cè)試產(chǎn)品,要么是極其不穩(wěn)定的手動(dòng)搖表測(cè)試產(chǎn)品,所以,根據(jù)航天企業(yè)實(shí)際需求,研發(fā)出一種可靠性高、價(jià)格適中、能滿足多點(diǎn)測(cè)量、易操作的絕緣擊穿測(cè)試設(shè)備顯得尤為重要。本課題包括設(shè)計(jì)與絕緣測(cè)試儀相匹配的可靠控制電路、轉(zhuǎn)接裝置,并將它們有效的聯(lián)系起來(lái),同時(shí)也包括PCB設(shè)計(jì)、測(cè)試臺(tái)結(jié)構(gòu)設(shè)計(jì)、生產(chǎn)工藝研究等內(nèi)容,最終完成整個(gè)絕緣擊穿測(cè)試臺(tái)的研制。絕緣擊穿測(cè)試臺(tái)可以對(duì)儀器或電纜的絕緣電阻、耐壓強(qiáng)度進(jìn)行測(cè)試,該設(shè)備可靠性好、效率高、操作簡(jiǎn)單、通用性強(qiáng),可以進(jìn)行大規(guī)模絕緣點(diǎn)間絕緣電阻測(cè)試和抗電強(qiáng)度的測(cè)試,保證了產(chǎn)品的電氣性能,提高了測(cè)試效率,提高產(chǎn)品出廠的可靠性。
[Abstract]:As a part of the whole system, instrumentation and cable harness play a decisive role in aerospace military products. The quality of instruments and cables directly determines the quality of the products. As a key link to ensure the overall quality, the inspection has been highly valued by the aerospace military manufacturing enterprises. The insulation resistance and voltage resistance of the products are important factors related to the quality of the products. At present, there are either expensive automated test products or extremely unstable hand-shaking meter test products in the market, so, According to the actual demand of spaceflight enterprises, it is very important to develop a kind of insulation breakdown test equipment with high reliability and moderate price, which can satisfy the multi-point measurement and is easy to operate. This subject includes the design of reliable control circuit, connecting device, and connecting them effectively with the insulation tester. At the same time, it also includes the design of PCB, the structure design of test bench, the research of production technology, etc. Finally, the development of the whole insulation breakdown test bench is completed. The insulation breakdown test bench can test the insulation resistance and voltage strength of the instrument or cable. The equipment has good reliability, high efficiency, simple operation and strong versatility. Large scale insulation resistance test and electrical strength test can be carried out to ensure the electrical performance of the product, improve the testing efficiency and improve the reliability of the product.
