Abstract
The utility model belongs to the technical field of electricians, and a current transformer takes a silicon steel sheet as a magnet core, and a primary of the current transformer is a single turn high voltage line, and the current which is output by a secondary of the current transformer charges to a battery by a rectification control circuit, then the needed various voltages can be obtained by a general electronic technology, and the zero point of the power voltage is connected at the high voltage line.
Description
The utility model belongs to electrical technology field.
It is feasible that high-voltage hot-line work all proves in theory and practice, and just more convenient if electric meter is placed high-pressure side, this solves the problem of long-lived low-tension supply with regard to needs.
The purpose of this utility model provides a kind of low-tension supply, obtains energy from high-voltage line, to the storage battery charge, makes power supply durable in use.
The purpose of this utility model is achieved in that the current transformer CT that is made magnetic core by silicon steel sheet, elementary is the single turn high-voltage line, the electric current of its secondary output is through over commutation, control circuit is to the storage battery charge, obtain needed each sharp voltage with the universal electric technology again, be connected on the high-voltage line zero point of supply voltage.
Owing to adopt such scheme, make this power volume little, in light weight, make simply, the electric energy of storage battery obtains additional and durable in use, model machine and electronic instrument on the 10KV electrical network 6 months on probation are stable and reliable for performance.
Below in conjunction with drawings and Examples the utility model is further specified.
CT is a current transformer among the figure, and its elementary winding is single turn high-voltage line AA ', and two terminals of secondary winding are connected on y
1And y
2On the point, its magnetic core is manufactured by silicon steel sheet, and the zero level point O of power supply is connected on the high-voltage line, and the positive pole of storage battery G is connected on y
3On the point, its negative pole is connected on y
4On the point, desirable 6V of the voltage of G or 12V, the power of low-tension supply is 5 watts if desired, when high-voltage line flows through 30% rated current, the secondary current of CT should be about 1 peace, for preventing the impact of high-voltage line short circuit current, and the impact that the secondary winding of CT should be able to the electric current of anti-50A; Because the zero point and the high-voltage line equipotential of power supply, the making of CT does not need to consider high voltage bearing problem, should make V by the rule of low-voltage current mutual inductor
