The beneficial effects of the utility model are：Because the first diode has one-way conduction so that either direct current
Source or AC power, when the first bulb is lighted, it is necessarily fixed by the sense of current of transformer first coil, with
This can affirm the both positive and negative polarity situation of first coil, and the second diode also has one-way conduction, passes through the point of the second bulb
It is whether bright, the sense of current by the coil of transformer second can be also obtained, the both positive and negative polarity situation of the second coil is affirmed with this, is passed through
Contrast first coil and each proper negative pole situation of the second coil can obtain the polarity of two coils of transformer, and by making the
The guiding matching of one diode and the second diode, user can quickly obtain transformer by two whether lighting for bulb
Polarity, thus, the utility model not only power supply classification it is applied widely, and intuitive is strong, and operating efficiency is high.In addition, the
The setting of one resistance and second resistance is to prevent that electric current is excessive and puncture the first diode and the second diode causes this practicality new
The damage of type, can improve security of the present utility model.
In some embodiments, the utility model also includes the first chuck and the second chuck, wherein the first chuck is with opening
Close and be electrically connected with, the second chuck is electrically connected with first resistor.The setting of first chuck and the second chuck is this reality for convenience
With the new connection with power supply and the first coil of transformer, it is ensured that the reliability of connection.
In some embodiments, the utility model also includes the 3rd chuck and the 4th chuck, wherein the 3rd chuck and the
Two diodes are electrically connected with, and the 4th chuck is electrically connected with second resistance.The setting of 3rd chuck and the 4th chuck is for side
Just the connection of the second coil of the utility model and transformer, it is ensured that the reliability of connection.
