Research and implementation of safety measurement to bus insulation resistance

In this paper, it has been deeply analyzed and studied the safety measurement to bus insulation resistance in the production of smelting for long-term. According to the specific system characteristics, it has brought forward the test method of introducing filter module and the equivalent resistance while program-controlled amplifiers and high-precision A/D have been combined use. It made the measurement system with self-adaptive characteristics of measuring range to improve measurement accuracy. So it completely abandons the insecurity factor caused by the traditional single-use meter measurement. By several experimental measurements, it shows that the production methods used in this paper are feasible and safe. It can effectively overcome the impact of the magnetic field in the bus system, distributed capacitance, the stress field to measurement. It has great significance and broad application prospects to make system running smoothly, maintain balanced stable production, make a good bus system in a controlled state and ensure the entire production system safe running.
