The application method of the power equipment state intensive detection system according to claim 8, wherein the step 3) comprises: aiming at each state quantity in all the state quantities stored in a centralized way, comparing the state quantity with a preset standard value of the state quantity or a last state value, and determining the degradation degree of each state quantity and a corresponding state quantity deduction value; finally, weighting and summing the state quantity deduction values of all the state quantities stored in a centralized manner based on a preset weight coefficient to obtain a total state quantity deduction value; searching a preset score interval-evaluation result mapping table based on the score intervals of the state quantity deduction values of the single state quantities and the total state quantity deduction values, so as to obtain a final state evaluation result of the power equipment; the score interval-evaluation result mapping table includes a mapping relationship between score intervals and evaluation results of the power equipment states.
10. The application method of the power equipment state intensive detection system according to claim 8, wherein the power equipment state evaluation result includes a serious state, an abnormal state, an attention state, and a normal state; the step 3) also comprises the steps of summarizing the power equipment state evaluation results by taking the power intervals as units and judging each power interval as follows:
s1) if the power equipment state evaluation result of any power equipment in the power interval is in a serious state, determining that the state evaluation result of the power interval is in a serious state, and exiting; otherwise, jumping to execute step S2);
s2) if the power equipment state evaluation result of any one of the power equipments in the power interval is abnormal, determining that the state evaluation result of the power interval is abnormal, and exiting; otherwise, jumping to execute step S3);
s3) if one or more master devices in the power interval are in the attention state or the power device state evaluation result of two or more power devices is in the attention state, wherein the master devices refer to the main transformer or the circuit breaker in the power interval, determining that the state evaluation result of the power interval is in the attention state, and quitting; otherwise, at this time, the power equipment state evaluation results of all the power equipment in the power interval are in a normal state or the power equipment state evaluation result of one non-master power equipment is in an attention state, and the state evaluation result of the power interval is judged to be in the normal state.
