Description

technical field [0001] The invention relates to the technical field of DC power supply control, in particular to a silicon chain detection device. Background technique [0002] The power operating power supply in power plants and substations is currently using DC power supply, and the DC screen is used to supply this DC power supply. It provides power for control loads, power loads, and DC accident lighting loads. It is a contemporary power system. The basis for control and protection. [0003] As an important part of the DC screen, the silicon chain is a DC voltage regulator, which consists of multiple high-power diodes in series, and uses the superposition of the constant forward voltage drop of the PN junction of the high-power diodes to adjust the voltage. The current silicon chain detection technology is relatively simple and rough. Generally, several pointer-type voltmeters and ammeters are installed on the detection box to detect the performance of the silicon cha...

Problems solved by technology

Generally, several pointer-type voltmeters and ammeters are installed on the detection box to detect the performance of the silicon chain. The temperature can only be measured manually and cannot be displayed automatically, and the error is large. This method is relatively simple and intuitive, but the accuracy is not high, and it can only reflect In the instantaneous situation, there is no curve memory function, and the specific performance of the silicon chain under different voltage and current values ​​cannot be embodied; the data and curves of each silicon chain cannot be archived, and there is no basis for judgment in future maintenance
