In addition, since the power supply portion of the conventional electrical detection apparatus lacks a corresponding circuit protection function, for example: the safety and reliability of the circuit are poor due to the lack of the current-limiting protection function.

And because some components are saved, the hardware cost can be reduced. The fourth resistor R4 is a current limiting resistor, and is used for current limiting protection of the collector current of the first transistor Q1. The current limiting protection principle is as follows: when the collector current of the first triode Q1 is large, the fourth resistor R4 can reduce the collector current of the first triode Q1, so that the first triode Q1 can be kept in a normal working state, and the situation that components in the circuit are burnt out due to too large current is avoided, so that the safety and reliability of the circuit are high, and the technical effect better than that of the conventional technology is achieved by fewer components.

The second diode D2 is a current limiting diode for current limiting protection. The current limiting protection principle is as follows: when the current of the branch where the second diode D2 is located is large, the current of the branch where the second diode D2 is located can be reduced by the second diode D2, so that the branch can be kept in a normal operating state, and the components in the circuit cannot be burned out due to the large current, so as to further enhance the safety and reliability of the circuit. It should be noted that in this embodiment, the second diode D2 has a model number L-2733. Of course, in practical applications, the second diode D2 may also be another type of diode with similar functions.
