COMSOL仿真分析高压直流GIS/GIL绝缘性能优化高压直流气体绝缘设备(GIS/GIL)的绝缘性能是保障电网可靠运行的关键。通过COMSOL Multiphysics多物理场仿真，可以深入分析气固界面电场分布与电荷积聚机理。该技术结合静电场、热场和电荷传输耦合计算，能准确模拟温度梯度对SF6气体与环氧树脂界面特性的影响。工程实践中，这类仿真可优化导体结构设计、改进绝缘材料配方，并建立电场-温度关联预警模型。特别是在80℃高温工况下，仿真显示界面电荷密度会显著增加23%，这对设备安全运行具有重要指导价值。阅读详情

使用IP Helper(需要安装SDK)的GetAdaptersInfo　API函数，它可以枚举出当前OS下的有效的网卡信息，具体实现如下：

#include <Iphlpapi.h>
#pragma comment(lib, "Iphlpapi.lib")

// Get and print information from IP_ADDR_STRING structure.
void PrintIPs(PIP_ADDR_STRING pCurIP, bool bFullInf, CString &strADDRList)
{
strADDRList = "";
if (pCurIP->IpAddress.String[0] == '\0')
{
strADDRList = "not presented\n\n";
return;
}
CString strTemp;
if (bFullInf)
{
do
{
strTemp.Format("IP Addr:[%s] Subnet Mask:[%s]\r\n",
pCurIP->IpAddress.String,
pCurIP->IpMask.String[0] == '\0' ? "no" : pCurIP->IpMask.String);
strADDRList += strTemp;
} while ((pCurIP = pCurIP->Next) != NULL);
}
else
{
do
{
strTemp.Format("%s ", pCurIP->IpAddress.String);
strADDRList += strTemp;
} while ((pCurIP = pCurIP->Next) != NULL);
}

}

void GetNICInfo()
{

IP_ADAPTER_INFO * IpAdaptersInfo,*IpAdaptersInfoHead;
ULONG ulOutBufLen;
DWORD dwRetVal;
CString strMsg;
CString strOutPut;
IpAdaptersInfo = (IP_ADAPTER_INFO *) GlobalAlloc( GPTR, sizeof( IP_ADAPTER_INFO ));
ulOutBufLen = sizeof( IP_ADAPTER_INFO );

if( ERROR_BUFFER_OVERFLOW == GetAdaptersInfo(IpAdaptersInfo,&ulOutBufLen))
{
GlobalFree( IpAdaptersInfo );
IpAdaptersInfo =(IP_ADAPTER_INFO *) GlobalAlloc( GPTR, ulOutBufLen );
}

if ( dwRetVal = GetAdaptersInfo( IpAdaptersInfo, &ulOutBufLen ) )
{
strMsg.Format(
"Call to GetAdaptersInfo failed. Return Value: %08x\r\n",
dwRetVal );
strOutPut+=strMsg;
}
else
{
IpAdaptersInfoHead = IpAdaptersInfo;
do
{
strMsg.Format( "MAC Address: %02x-%02x-%02x-%02x-%02x-%02x\r\n",
IpAdaptersInfo->Address[0],
IpAdaptersInfo->Address[1],
IpAdaptersInfo->Address[2],
IpAdaptersInfo->Address[3],
IpAdaptersInfo->Address[4],
IpAdaptersInfo->Address[5]);
strOutPut+=strMsg;
PrintIPs(&(IpAdaptersInfo->IpAddressList),TRUE, strMsg);
strOutPut+=strMsg;
strOutPut+="\r\n";

IpAdaptersInfo = IpAdaptersInfo->Next;
} while (IpAdaptersInfo);
}
GlobalFree( IpAdaptersInfoHead );
AfxMessageBox(strOutPut);
