　　Features of wireless temperature early warning system: Temperature monitoring points in high voltage, high current, and strong magnetic field environments, and even some monitoring points in enclosed spaces, are unable to be used due to issues such as strong electromagnetic noise, high voltage insulation, and space limitations. The system uses radio waves to transmit data. The sensor is installed on the high-voltage device and is not electrically connected to the receiving device. So, this system fundamentally solves the problem of difficulty in online real-time monitoring of the working temperature of high-voltage equipment contacts. A high-voltage bus induction power supply has been designed for a wireless temperature measurement system for high-voltage equipment. The wireless temperature measurement module using this power supply works completely independently, without relying on the mains power supply of the substation, greatly improving the reliability of the monitoring system. Inductive coil design: Magnetic induction coil is the core part of bus power supply and also the design difficulty of bus power supply. The busbar current varies greatly, ranging from a few amperes to several thousand amperes. The rated current of 10kV high-voltage switchgear is 630A, 250A, 600A, etc. In the design of magnetic induction coils, it should be considered that when the bus current is low, the energy of the magnetic induction coil is very small, and the system cannot work properly; When the bus current exceeds the rated current, it is a strong current; Or in short-circuit fault currents, the high-voltage spike pulses generated by the magnetic induction coil can cause interference and damage to the secondary side of the equipment, especially to subsequent circuits. So, for situations where the bus current is relatively complex, the selection of magnetic induction coil core material is crucial. The currently available iron core materials include silicon steel, Permalloy, crystalline materials, etc. Through testing of this product, we have selected iron cores that meet the design requirements at a lower price, making this product more competitive in the industry. A coil turn design was proposed, and a simplified model for induced power recovery was proposed. Assuming that the primary and secondary coils are coupled with electromagnetic induction as a whole, without considering the leakage inductance of the primary and secondary coils, the model is simplified to operate the inductive device in an ideal state. In half a cycle of the bus current, the magnetic induction intensity should rise from negative saturation to saturation, at which point high power can be achieved, that is, the output voltage U2max. If the inductive device operates in an ideal state, during half a cycle of the bus current, the magnetic induction intensity of the iron core increases from negative saturation to positive saturation, and a higher power output voltage U2max can be obtained.
