Abstract
The utility model discloses a power converter which comprises a plug, a socket, a power module, a relay module, a main controller and a power detection module, wherein the plug is electrically connected with the socket through the relay module electrically connected with the main controller, the main controller is electrically connected with the plug through the power module, and the power detection module is respectively and electrically connected with the main controller and the socket. According to the structure, when the charging time of electrical element equipment which plugs in the power converter is too long, the main controller sends a disconnecting signal to the relay module and enables the whole circuit in the power converter to disconnect, and thereby the service life of the electrical element equipment is prolonged and the happening of fire disaster is avoided.
Description
Technical field
The utility model relates to electric field, specifically is a kind of power supply changeover device.
Background technology
At present, at the electric power on-site, a lot of equipment that using are to adopt lithium battery power supply; These equipment use the charging in evening often by day; The power supply changeover device that charging need be used in the prior art comprises pedestal and the plug that connects with electric wire, and pedestal is provided with one or more groups jack, and these jacks can all be two phases; Can all be three-phase, also can be two mutually and three combined.But the shortcoming below this power supply changeover device exists: possibly there is the problem of forgeing charging or overcharging for a long time in equipment after finishing using and playbacking.The work that can delay second day for the former; Can cause service life of equipment to shorten or damage for the latter, serious possibly cause fire.
The utility model content
The utility model technical problem to be solved is, a kind of power detection that has is provided, and can carries out over-charge protective, thereby prolong equipment useful life, avoid the power supply changeover device of fire happens.
For solving the problems of the technologies described above; The power supply changeover device that the utility model provides comprises plug, socket, power module, relay module and master controller, and described plug is electrically connected with socket through relay module; Relay module is electrically connected with master controller; Master controller is electrically connected with plug through power module, and it also comprises power detection module, and described power detection module is electrically connected with master controller and socket respectively; Relay module is when closure, and socket work produces power, makes power detection module begin to detect, and when detected power reached predetermined numerical value, master controller sends signal according to the analysis of numerical value to relay module made it that entire circuit is broken off.
After adopting above structure, the utility model with compared with techniques is arranged, have the following advantages: owing on the master controller of power supply changeover device, be provided with power detection module; Like this, when the overlong time that is inserted in the electric component equipment charge on the power supply changeover device, promptly the power on the power supply changeover device is excessive and when surpassing the numerical value that advance notice sets; Master controller will send the signal of disconnection to relay module, thereby the entire circuit in the power supply changeover device is broken off, in other words; Electric component equipment will stop charging; Therefore, the useful life of electric component equipment can be prolonged, also fire happens can be avoided.
Description of drawings
Accompanying drawing is the electrical schematic diagram of the utility model power supply changeover device.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done explanation in further detail.
Electrical schematic diagram by the utility model power supply changeover device shown in the drawings can be known; It comprises plug, socket, power module, relay module and master controller; Described plug is electrically connected with socket through relay module; Relay module is electrically connected with master controller, and master controller is electrically connected with plug through power module.This power supply changeover device also comprises power detection module, and described power detection module is electrically connected with master controller and socket respectively.
The operation principle of the utility model is: when relay module during in closure; Socket work produces power; Make power detection module begin to detect, when detected power reached predetermined numerical value, master controller sends signal according to the analysis of numerical value to relay module made it that entire circuit is broken off.
