【摘要】：在航天軍工產品中,儀器設備、線纜線束,作為整個系統(tǒng)的一部分,起著決定性作用。儀器和線纜的質量直接決定了產品的質量,其檢測作為保證整體質量的關鍵環(huán)節(jié),已受到航天軍工制造各企業(yè)的高度重視。產品的絕緣電阻特性及耐壓性能是關系到產品質量優(yōu)劣的重要因素,目前市場上存在的要么是價格高昂的自動化測試產品,要么是極其不穩(wěn)定的手動搖表測試產品,所以,根據(jù)航天企業(yè)實際需求,研發(fā)出一種可靠性高、價格適中、能滿足多點測量、易操作的絕緣擊穿測試設備顯得尤為重要。本課題包括設計與絕緣測試儀相匹配的可靠控制電路、轉接裝置,并將它們有效的聯(lián)系起來,同時也包括PCB設計、測試臺結構設計、生產工藝研究等內容,最終完成整個絕緣擊穿測試臺的研制。絕緣擊穿測試臺可以對儀器或電纜的絕緣電阻、耐壓強度進行測試,該設備可靠性好、效率高、操作簡單、通用性強,可以進行大規(guī)模絕緣點間絕緣電阻測試和抗電強度的測試,保證了產品的電氣性能,提高了測試效率,提高產品出廠的可靠性。
[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.
