摘要
避雷器(MOA)的保护性能对变压器及其他电气设备的绝缘水平的确定有着直接的影响,其中MOA的电位分布及温度分布情况决定了整只MOA的运行寿命。在进行合理均压措施的情况下,会有效减缓MOA老化,降低热崩溃的可能性。对MOA的电位分布情况进行测试是为MOA进行均压调整的必要手段。采用高性能便携式微处理器和无线同步采集技术,设计了基于无线采集技术的MOA电位分布及温度分布系统。对MOA电位分布及温度分布情况以无线同步方式进行测试是对传统基于有线光纤方式检测手段进行测试的升级,简化了现场繁琐的光纤布线,提高了测试数据的准确度。根据MOA测试到的电压分布及温度分布情况,为后续采取MOA均压提供了有效数据,有利于电网的安全可靠运行。
The protection performance of lightning arrester( MOA) has direct impact on insulation level of the transformer and other electrical equipment, the potential distribution and the temperature distribution of the arrester determines the operating life of a lightning arrester. In the case of reasonable pressure sharing measures, it will effectively slow down the aging of arrester and reduce the possibility of thermal collapse. It is necessary to test the potential distribution of arrester to adjust the voltage distribution of ar-rester. The design uses high performance portable microprocessor, wireless synchronous acquisition technology, design of the lightning arrester potential distribution and temperature distribution system based on wireless acquisition technology. The arrester potential dis-tribution and temperature distribution in the wireless synchronization testing is the traditional way of fiber-optic cable test methods based on test upgrade, which simplifies the tedious scene of fiber-optic cabling and improves the accuracy of the test data. According to the voltage distribution and temperature distribution measured by the arrester, effective data are provided for subsequent voltage sharing of the lightning arrester, which is beneficial to the safe and reliable operation of the power grid.
