Emerson HD22010-- 3 charging module

Module introduction

HD22010-3 series charging module is the most important configuration module of power supply, widely used in 35kV to 330kV substation power supply. This series of products is the optimization of HD22010-2 series charging module, and its performance indicators are better than HD22010-2 charging module. HD22010-3 series charging module adopts a combination of self-cooling and air cooling, self-cooling operation in light load, in line with the actual operation of the power system. The dimensions of the module are the same as the HD22005-3 charging module, so the power density of the module is increased.

The HD22010-3 charging module consists of two power parts: three-phase passive PFC and DC/DC. In addition to the two power parts, there is an auxiliary power supply and input and output detection protection circuit.

The front-end three-phase passive PFC circuit is composed of input EMI and passive PFC to achieve AC input rectification and filtering and input current correction, so that the input circuit power factor is greater than 0.92 to meet the three-phase harmonic standard in DL/T781-2001 and the relevant EMI and EMC standards in GB/T 17794.2.2-2003. The DC/DC circuit of the rear stage is composed of the DC/DC converter and its control circuit, rectification filter, output EMI, etc., which is used to convert the former rectifier voltage into the stable DC voltage output required by the power operating system.

After the input of passive PFC and before the DC/DC converter, the auxiliary power supply uses the DC output of the three-phase passive PFC to generate the various power supplies required by the control circuit.

The input detection circuit realizes the detection of input over and under voltage and lack of equality. DC/DC detection protection circuit includes output voltage and current detection, heat sink temperature detection, etc. All these signals are used for DC/DC control and protection.
