Abstract
The utility model discloses a kind of power power-supply current transformer of electrical malfunction, comprise an iron core, iron core is wound with former limit winding and vice-side winding; Vice-side winding comprises the first vice-side winding and the second vice-side winding; The rated current of former limit winding is 600A, and the no-load voltage ratio of current transformer is 600/5A, and when former limit winding is without input, the input current of the first vice-side winding is 3A, and the power output of the second vice-side winding is greater than 150VA; By adopting technique scheme, on the basis of same volume construction profile, power stage is far longer than common current transformer; Due to the utility model by multiple winding technique on same iron core, on the basis ensureing product electric property, greatly save raw-material use, reduce production cost, can better market be adapted to; When the high-pressure side no signal current of electrical system, can at low-pressure side input signal, guarantee electric energy instrument, measurement mechanism normally run.
Description
Technical field
The utility model relates to current transformer technical field, particularly relates to a kind of power power-supply current transformer of electrical malfunction.
Background technology
Current transformer principle is according to electromagnetic induction principle.Current transformer is made up of the iron core closed and winding.Current transformer and transformer ' s type like being also according to electromagnetic induction principle work, transformer conversion being voltage and current transformer conversion be electric current.Current transformer connects the winding (number of turn is N1) of tested electric current, is called a winding (or former limit winding, armature winding); The winding (number of turn is N2) connecing measuring instrument is called secondary winding (or vice-side winding, secondary winding).
Traditional current transformer iron core can only around a winding, product is containing palpus multiple iron core during multiple secondary winding, therefore limit by inner space, attainable secondary power output is less, the instructions for use of power power-supply cannot be met, and break down in electrical system, high-pressure side no signal current input time, low-pressure side cannot normally work.
Utility model content
The technical problems to be solved in the utility model is: provide one can realize high-power output, and break down in electrical system, high-pressure side no signal current input time, the power power-supply current transformer of the electrical malfunction that low-pressure side still can normally work.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A power power-supply current transformer for electrical malfunction, is characterized in that: comprise an iron core, described iron core is wound with former limit winding and vice-side winding; Described vice-side winding comprises the first vice-side winding and the second vice-side winding; The rated current of described former limit winding is 600A, and the no-load voltage ratio of described current transformer is 600/5A, and when former limit winding is without input, the input current of described first vice-side winding is 3A, and the power output of described second vice-side winding is greater than 150VA.
The advantage that the utility model has and good effect are: by adopting technique scheme, on the basis of same volume construction profile, power stage is far longer than common current transformer; Because multiple winding (the utility model is specially three windings) is wound on same iron core by the utility model, on the basis ensureing product electric property, greatly save raw-material use, reduce production cost, can better market be adapted to; When the high-pressure side no signal current of electrical system, can at low-pressure side input signal, guarantee electric energy instrument, measurement mechanism normally run.
Accompanying drawing explanation
Fig. 1 is internal structure schematic diagram of the present utility model;
Fig. 2 is electronic schematic diagram of the present utility model;
Embodiment
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of power power-supply current transformer of electrical malfunction, comprise an iron core, described iron core is wound with former limit winding and vice-side winding; Described vice-side winding comprises the first vice-side winding and the second vice-side winding; The rated current of described former limit winding is 600A, and the no-load voltage ratio of described current transformer is 600/5A, and when former limit winding is without input, the input current of described first vice-side winding is 3A, and the power output of described second vice-side winding is greater than 150VA.In order to ensure the security performance of product, preventing short circuit, between winding layers, being provided with insulation coiling layer.
Due to by two vice-side winding around on same iron core, make all have magnetic coupling between two between former limit winding and the first vice-side winding and the second vice-side winding, namely primary current can induce electric current on the second vice-side winding, and the first vice-side winding also can induce electric current on the second vice-side winding.
When electrical system breaks down power-off, by the first vice-side winding side input AC electricity, thus power to the second auxiliary winding, make electric energy instrument, measurement mechanism do not affect by high-pressure side, reach the object of stable operation.
This specific embodiment tool has the following advantages:
1, save the raw-material uses such as unshakable in one's determination, reduce product cost;
2, owing to only using an iron core, therefore easy to operate, quick, decrease the operating time of wrapping unshakable in one's determination and secondary winding conjunction bag, substantially increase production efficiency.
3, meet when electrical system breaks down, the new demand that electric energy instrument device normally runs, more traditional current transformer advantageously, can better meeting the market requirement.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
