摘　　要：现有的电缆故障检测系统是对复杂电缆网络短路、断路故障自动检测的系统,但不具备对电缆网络导线之间绝缘性进行测试的能力。本文研制了一个与原有电缆故障检测系统兼容的绝缘测试单元,阐述了绝缘电阻测量模块、通道选择模块、高压产生模块、EPLD译码模块等电路的设计实现过程,实现对电缆网络的绝缘测试。The existing testing system of cable is an instrument to test the complex cable network and detect the failure of the circuit.It can automatically detected the open-circuit and short-circuit,yet,it can not test the insulation resistance between the cable network.In this thesis,an insulation test unit of cable is developed,it is compatible with the existing testing system.It achieves the circuit such as the insulation resistance measurement module,the channel selection module,the high-voltage module,the EPLD decoding module and achieved the expected results.
