Description
Technical field
The present invention relates to the application of electromagnetic induction, particularly relate to a kind of suspension electricity getting device.
Background technology
Traditional utilize current transformer as take can equipment carry out suspension power taking time, there is a peak power output in current transformer, its square being directly proportional to current transformer primary side current. Therefore, along with the increase of primary side current, the output of current transformer is increased sharply by zero, and high-power output certainly will cause the heat consumption of higher voltage and Geng Gao, makes load elements heating serious, it is possible to jeopardize the safety of load equipment; And when the power that transformer exports or voltage exceed the ability to bear of load, load equipment certainly will be damaged.
Therefore, traditional current transformer that utilizes can carry out suspension power taking by equipment as taking, and can only be powered in the current range that current transformer primary side is less; When current transformer primary side current suddenlys change, it is impossible to normal power taking or be easily damaged energy taking device.
Summary of the invention
It is an object of the invention to propose a kind of suspension electricity getting device, it is possible to when circuit primary side current changes that relatively value range is wider, meeting taking of terminal can demand reliability when improving suspension power taking.
The scheme adopted:
A kind of suspension electricity getting device, including: current transformer, controller, diode rectification mu balanced circuit, first control switch, the resistance and second of multiple different resistances controls switch;
Wherein, described controller connects the primary side of current transformer, the outfan of described diode rectification mu balanced circuit, described first control switch and described second control switch;

The other end of each described resistance connects the second input of described diode rectification mu balanced circuit;
Described second one end controlling switch connects each described second outfan, and described second other end controlling switch connects the second input of described diode rectification mu balanced circuit.
In the present invention, when Current Transformer Secondary side is supplied to the voltage of load higher than the voltage preset, increases the resistance with load equivalent resistor coupled in parallel, carry out current distributing, be reduced to the electric current of load; When Current Transformer Secondary side is supplied to the voltage of load higher than the voltage preset, increase the coil turn of Current Transformer Secondary side, reduce the induced voltage of secondary side, thus reducing the power being supplied to load, when the electric current of current transformer primary side becomes big suddenly, it is also ensured that taking of current transformer can requirement; The increase along with primary side current can be solved, the problem that high heat consumption that the output of current transformer is increased sharply by zero and causes, device are easily damaged; Therefore, the present invention can when circuit primary side current changes that relatively value range is wider, and meeting taking of terminal can demand reliability when improving suspension power taking.
Accompanying drawing explanation
Fig. 1 is a structural representation of apparatus of the present invention.
Detailed description of the invention
The present invention proposes a kind of suspension electricity getting device, one of them structural representation refer to Fig. 1, including: current transformer, controller, diode rectification mu balanced circuit, first control switch K1, the resistance (R1, R2 ... Rn) and second of multiple different resistances controls switch K2;
Wherein, controller connects the primary side of current transformer, the outfan of diode rectification mu balanced circuit, the first control switch K1 and second control switch K2;
Current transformer includes the first outfan and multiple second outfan (N1, N2 ... Nn);
First outfan of current transformer connects the first input end of diode rectification mu balanced circuit;
First input end connects one end of multiple resistance by the first control switch K1, and the resistance of each resistance is different;

Second one end controlling switch K2 connects each the second outfan, and second other end controlling switch K2 connects the second input of diode rectification mu balanced circuit.
In the present invention, when Current Transformer Secondary side is supplied to the voltage of load higher than the voltage preset, increases the resistance with load equivalent resistor coupled in parallel, carry out current distributing, be reduced to the electric current of load; When Current Transformer Secondary side is supplied to the voltage of load higher than the voltage preset, increase the coil turn of Current Transformer Secondary side, reduce the induced voltage of secondary side, thus reducing the power being supplied to load, when the electric current of current transformer primary side becomes big suddenly, it is also ensured that taking of current transformer can requirement; The increase along with primary side current can be solved, the problem that high heat consumption that the output of current transformer is increased sharply by zero and causes, device are easily damaged; Therefore, the present invention can when circuit primary side current changes that relatively value range is wider, and meeting taking of terminal can demand reliability when improving suspension power taking.
In Fig. 1 embodiment, first controls to switch for single pole multiple throw or double-pole multithrow switch;
Second controls to switch as single pole multiple throw or double-pole multithrow switch. First control switch, the second control switch can also be other gate-controlled switches.
When arranging the resistance that the first control switch controls, can arrange according to the size order of resistance. So as the first control controlling switch.
When meeting the output voltage of diode rectification mu balanced circuit below or equal to predetermined magnitude of voltage, and when meeting the primary side current of current transformer less than or equal to default first electric current, the suspension electricity-fetching method of the present invention can ensure that the safety of the device of load, make the present invention can when current transformer primary side current changes greatly, ensure the safety of suspension power taking, meet power taking requirement.
In the present invention, when Current Transformer Secondary side is supplied to the voltage of load higher than the voltage preset, increases the resistance with load equivalent resistor coupled in parallel, carry out current distributing, be reduced to the electric current of load; When Current Transformer Secondary side is supplied to the voltage of load higher than the voltage preset, increase the coil turn of Current Transformer Secondary side, reduce the induced voltage of secondary side, thus reducing the power being supplied to load, when the electric current of current transformer primary side becomes big suddenly, it is also ensured that taking of current transformer can requirement; The increase along with primary side current can be solved, the problem that high heat consumption that the output of current transformer is increased sharply by zero and causes, device are easily damaged; Therefore, the present invention can when circuit primary side current changes that relatively value range is wider, and meeting taking of terminal can demand reliability when improving suspension power taking.
Above example only have expressed the several embodiments of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention. It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention. Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
