9. The power transformation relay protection abnormity identification system based on main and auxiliary data fusion according to claim 8, wherein the power transformation main and auxiliary equipment monitoring main station system is specifically used for,
extracting data of the same breaker monitored by the measurement and control device, the protection device and the online monitoring device to form association;
for the same circuit breaker, calculating the Total opening and closing times R _ Total = (R _ S0+ R _ S1) of the circuit breaker by a protection device according to the accumulated tripping times R _ S0 and the accumulated closing times R _ S1 of the circuit breaker by the protection device;
according to the cumulative opening times M _ S0 and the cumulative closing times M _ S1 of the circuit breaker, which are acquired by the measurement and control device, calculating the Total opening and closing times M _ Total = (M _ S0+ M _ S1) of the circuit breaker, which are acquired by the measurement and control device;
calculating the Total opening and closing times A _ Total = (A _ S0+ A _ S1) of the circuit breaker, which are acquired by the online monitoring device, according to the accumulated opening times A _ S0 and the accumulated closing times A _ S1 of the circuit breaker, which are acquired by the online monitoring device;
and if the R _ Total, the M _ Total and the A _ Total are not equal or the R _ S0, the M _ S0 and the A _ S0 are not equal, judging that the relay protection device of the circuit breaker is abnormal.
