Advantages of the present invention effect is as follows:
1st, the material of casing is aluminium sheet material, and equipped with ground terminal, it is ensured that casing grounding safety is reliable, it is ensured that personal security.
It is furnished with universal wheel and handle, conveniently moving outside casing.
2nd, can be by user's main power source and power autonomous carry out automatic conversion by dual-power transfer switch, it is movable to
The electric field of any required double power-supply automatic transferring, and very easily move at the scene, do not limited by any place
System, solves the trouble that manual switching is brought, and improves the electric timeliness of guarantor and level, shortens power off time, it is ensured that power supply
Reliability, improves power supply quality.
3rd, by dual-power automatic switching instead of it is original manually switch, greatly improve power supply reliability and safety
Property, original switching time was foreshortened within 3 seconds, so as to reach uninterrupted power supply, and all kinds of burst accident influence users are prevented
Important electricity consumption, this device can meet one, the two class power load requirements of support, and can easily be moved to showing for needs guarantor's electricity
, ability and level that electric company protects electricity to special electricity consumption place are improved, the power transmission of falling of artificial incorrect operation generation is prevented, realizes
It is intelligent and rapid in low-voltage dual power transfer process.
