The input terminal and output end of device P is answered, to test whether power supply device P meets safety standard.Then, in step S03 and
In step S04, with above-mentioned Hi-pot test power supply impose high voltage to power supply device P for a period of time after, e.g. one minute,
Hi-pot test power supply is removed, completes testing process at this time.Finally, lock member 43 is locked as described in step S05, by
One earthing member 41 and the second earthing member 42 are electrically connected to external conductive casing 1 and are grounded, and so just lightning strike protection module can be made normal
Actuation.
In addition, being other flow chart of steps of voltage test method referring to figure 3. shown in C.Carry out step S05 it
Before, voltage test method, which may also include, carries out the detection of input side over the ground, and step includes: to connect one end of Hi-pot test power supply
Input side is connect, the other end is grounded (S11)；High voltage is imposed in power supply device by Hi-pot test power supply, and is continued another
Predetermined time (S12)；And after by another predetermined time, remove Hi-pot test power supply (S13).
In step s 11, it can be connected to external conductive casing 1 at the ground connection of Hi-pot test power supply, or is connected to power supply device P
Other ground terminals, with can by voltage jump in input side 21 and ground connection.Then step S12 and step S13 is carried out, with
Above-mentioned Hi-pot test power supply impose high voltage to power supply device P for a period of time after, e.g. one minute, remove Hi-pot test
Power supply completes the Hi-pot test process of input side over the ground at this time.
In addition, being other flow chart of steps of voltage test method referring to figure 3. shown in D.Similarly, it is being walked
Before rapid S05, voltage test method may include carrying out the detection of outlet side over the ground, and step includes: by the one of Hi-pot test power supply
End connection outlet side, the other end are grounded (S21)；High voltage is imposed in power supply device by Hi-pot test power supply, and is continued
Another predetermined time (S22)；And after by another predetermined time, remove Hi-pot test power supply (S23).Wherein, it exports
The detection mode of side over the ground is roughly the same with the detection mode of above-mentioned input side over the ground, and difference is only that the one of Hi-pot test power supply
End connection outlet side 22 rather than input side 21, and the other end is similarly ground connection, and other steps can refer to above-mentioned, no longer go to live in the household of one's in-laws on getting married in this
It states.
It is noted that whether input side described in step S02~S04 is to output in above-mentioned voltage test method
The Insulation monitoring of side, the Insulation monitoring of input side over the ground described in step S11~S13 also or described in step S21~S23 export
The Insulation monitoring of side over the ground, the sequencing of three kinds of Insulation monitorings has no absolute relationship, and the present embodiment is defeated first to carry out
Enter side to be illustrated the Insulation monitoring of outlet side.
In conclusion the design of power supply device of the invention by earthing module, same by single a lock member
When pass through the first earthing member, the second earthing member and external conductive casing so that the first lightning strike protection module and the second lightning strike protection module
Identical ground terminal can be shared, rather than is respectively and electrically connected to external conductive casing by different lock member and is grounded, therefore
The usage amount of lock member can be reduced, and saves the use space inside power supply device.In addition, carrying out in production high
When pressure test, lock member can first unclamp removal and keep the first earthing member, the second earthing member and external conductive casing mutually not electric each other
Property connection and with ground disconnect, the outside of lock member self-conductive shell is internally locked again after pending Hi-pot test,
So that the first earthing member, the second earthing member and external conductive casing are electrically connected with each other and are grounded, thus simplify testing process.
