As shown in fig. 1, the health assessment method includes the steps of:
step S1: and receiving an actual measurement temperature value obtained by monitoring the temperature measurement sensor corresponding to each temperature measurement point, and calculating an actual measurement temperature rise value of each sub-chamber according to the actual measurement temperature value.
Each temperature measuring sensor transmits the temperature value obtained by real-time monitoring to the server, the server collects the actual measurement temperature value on each temperature measuring point, and name marking is carried out on the real-time temperature value according to the collection source, so that the situation of confusion is caused by too much collected data is avoided.
In addition, whether the measured temperature value of each temperature measuring point exceeds a preset alarm value or not needs to be judged, if yes, a corresponding overheating alarm prompt is generated for the sub-chamber corresponding to the measured temperature value, and if not, an alarm prompt does not need to be made.
After the server collects the temperature data, the corresponding measured temperature rise value is calculated, in the embodiment, the absolute temperature rise is adopted for calculation, the absolute temperature rise adopts the temperature difference between the current time temperature and the current environment temperature, and the ideal value is compared with the measured value for diagnosis; for example: when the power equipment is a ring main unit, the temperature collected by the temperature sensors of the three sub-chambers of the switch air box, the fuse chamber and the cable chamber is the current time temperature of each sub-chamber, the temperature collected by the temperature sensor on the outer surface of the main body is the current environment temperature, and the difference value between the current time temperature and the current environment temperature of each sub-chamber is the actual measurement temperature rise value of the sub-chamber; after the actual measured temperature rise value of each sub-chamber is calculated, the process proceeds to step S2.
Step S2: and calculating a theoretical temperature rise value of each chamber under the current environment by combining the load current data obtained by monitoring.
