The power supply using is at present when waveform shakiness appears in input voltage, and while especially there is larger surge ripple due to thunder and lightning factor, the voltage waveform of its output also can be affected.In addition, so be the situation that misoperation causes accident power-off because power supply master switch exists people by manual control.The plug model of simultaneously present import electrical equipment is varied, and conventional socket aperture cannot meet the user demand of the electrical equipment of different model plug.
Utility model content
The purpose of this utility model is to provide a kind of supply unit.
For realizing above-mentioned utility model object, a kind of supply unit of the present utility model, it comprises:
Supply module, it has the first output;
Filtration module, for carrying out filtering processing to the waveform of the voltage of exporting from the first output;
Overload protection module, for when there is overload situations in supply unit place circuit, the path of cutting off the electricity supply;
Master control grill-protected, the power-off when avoiding master switch surprisingly to turn-off;
Output interface module, it comprises the socket aperture matching with external equipment.
As further improvement of the utility model, described filtration module comprises filtering protected location and Anti-surging unit.
As further improvement of the utility model, described overload protection module comprises protection switch.
As further improvement of the utility model, described supply unit also comprises the ammeter of indicator current value.
As further improvement of the utility model, the shock-resistant electric current of the maximum of described supply unit is more than or equal to 20KA.
As further improvement of the utility model, the deboost of described supply unit is less than or equal to 500V.
Compared with prior art, the beneficial effects of the utility model are: the damage that supply unit of the present utility model can avoid the factors such as voltage waveform shakiness to cause electrical appliance, can avoid people is the accident power-off causing.Can also meet the user demand of the plug of different model, and realize efficient, stable operation simultaneously when guaranteeing electrical appliance safety.
Accompanying drawing explanation
Fig. 1 is the module diagram of an embodiment of supply unit of the present utility model.
Embodiment
Below in conjunction with each execution mode shown in the drawings, the utility model is elaborated; but should be noted that; these execution modes are not limitation of the utility model; those of ordinary skills are according to these execution mode institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection range of the present utility model.
As shown in Figure 1, supply unit 100 of the present utility model comprises supply module 10, and this supply module 10 has the first output, and it is for exporting the electric current of supply module 10.In order to prevent that the voltage of supply module 10 outputs from occurring that waveform is unstable; or during the waveform surge that thunder and lightning causes; supply unit 100 comprises filtration module 20; it is for carrying out filtering processing to the voltage of the first output output; to guarantee the stability of waveform of the voltage of output, and then the electric equipment that is connected with supply unit of protection.Particularly, above-mentioned filtration module 20 comprises filtering protected location 201 and Anti-surging unit 202.
Further, in order to prevent that the infringement that the abnormal conditions of overload or short circuit cause from appearring in supply unit 100 place circuit, supply unit 100 also comprises overload protection module 30.This overload protection module 30 comprises protection switch, when above-mentioned abnormal conditions occur, and protection switch deenergization device place path, and then protection power source device.The shock-resistant electric current of maximum of above-mentioned supply unit 100 is more than or equal to 20KA, and its deboost is less than or equal to 500V.
The master switch of supply unit 100 is with master control grill-protected 40, its power-off when preventing from causing the shutoff of master switch because of artificial faulty operation.
For the current value that indication supply unit 100 is exported in real time, supply unit 100 also comprises an ammeter.Further, supply unit 100 comprises output interface module 50, and it is for being electrically connected with outside electric equipment.In order to adapt to the plug of the electric equipment that does not supply model, above-mentioned output interface module 50 comprises the socket aperture of standard system.
The damage that supply unit of the present utility model can avoid the factors such as voltage waveform shakiness to cause electrical appliance, can avoid people is the accident power-off causing.Can also meet the user demand of the plug of different model, and realize efficient, stable operation simultaneously when guaranteeing electrical appliance safety.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limiting related claim.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other execution modes that it will be appreciated by those skilled in the art that.
