摘要:
随着电力系统中输电容量的不断扩大,电容式电压互感器(CVT)在中、高压电网中应用日渐广泛。目前检测CVT误差需要谐振升压装置、标准电压互感器、电压负载箱、互感器校验仪等设备,存在设备笨重、工作效率低等问题。该文在分析CVT的数学模型和目前CVT现场误差检测存在不足的基础上,研制了CYTE1型750 kV CVT测试与校验系统,采用电容式电压互感器间接误差测试方法,只需在相对低的电压下测试CVT的参数,再外推至80%~115%额定电压下的误差即可,提高了工作效率,减轻了工作人员劳动强度,保障生产安全,确保测
Abstract:
With the expansion of transmission capacity in power system, capacitance type voltage transformer (CVT) is widely used in medium voltage power grid and high voltage power grid. Detecting the error of CVT needs the equipment such as resonant booster, standard voltage transformer,voltage load box,transformer calibrator,etc.,which has the problems of heavy equipment and low working efficiency. In this paper, based on the analysis of the mathematical model of the CVT transmission and disadvantages on the basis of the current CVT on-site error detection, CYTE1 type 750 kV CVT is developed test and calibration system, using indirect error test method, the capacitor voltage transformer (CVT), the error can be pushed to 80%~115% of the rated voltage, it can improve the working efficiency, reduce the labor intensity of the staff, ensure the production safety, and ensure the accuracy of the test.
