Can anyone explain this??

The 4066 is a quad switch, think of it as a SPST.
It appears to be a circuit to sample voltage and current, under remote control from some other source (hence the 4066).
U2A is a virtual ground, so the op amps can use a single power supply and still swing plus and minus.
U2C is a simple buffer, R13 and R16 are simple voltage dividers feeding U2D, another simple buffer. The end result is a very overcomplicated voltage probe.
Not sure what U3 is, the 4066 switch allows it to switch ranges. It is implied that it measures the current flow, though how is missing.
