Abstract
A high-current generator has a plurality of converters, wherein the primary winding of the plurality of converters are respectively connected in parallel to the power input terminal through corresponding selection switches in a same polarity, the secondary winding of the plurality of converters are respectively connected in parallel to the current output terminal in a same polarity, and an auto-coupling voltage regulator is connected between the primary winding of one of the converter and the corresponding selection switch. The utility model adopts a plurality of parallel connected converters with identical capacity and parameter and arranges an auto-coupling voltage regulator with corresponding capacity to one of the converters to constitute a high-current generator. Because the capacity of the auto-coupling voltage regulator is only corresponding to the capacity of a single converter, the weight of the high-current generator is considerably alleviated, so as to realize the integration of the apparatus, bring convenience to the use of the high-current generator, and reduce the fabrication cost and energy consumption of the apparatus.
Description
Technical field
The utility model relates to a kind of strong current generator.
Background technology
General current feedback circuit is made up of current transformer and automatic coupling voltage regulator two parts.The weight of the current transformer of strong current generator is relatively large, the weight of the automatic coupling voltage regulator of capacity coupling is approaching with it with it, therefore output current is greater than the current feedback circuit of 4000 peaces, in use move for convenient, the split-type structurals that adopt more, be difficult to the integrated of the equipment of realizing, the cost of equipment and energy consumption are improved, make troubles also for the use of equipment.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of and can effectively alleviate weight of equipment, thereby can realize the integrated of equipment, and reduce the strong current generator of equipment manufacturing cost and energy consumption.
The technical scheme that realizes above-mentioned purpose is: a kind of strong current generator, it includes current transformer and automatic coupling voltage regulator, the elementary winding of its a plurality of current transformers is parallel to power input by corresponding selector switch respectively by the same polarity mode, the secondary winding of each current transformer is parallel to current output terminal respectively by the same polarity mode, is connected automatic coupling voltage regulator between the elementary winding of a current transformer therein and selector switch.
The technical solution of the utility model also comprises: be connected with isolating switch at power input, be connected with current transformer and the ammeter and the voltmeter of phase configuration with it at current output terminal.
The utility model adopts the current transformer parallel connection identical with parameter of a plurality of capacity, and be one of them current transformer configuration and the corresponding automatic coupling voltage regulator of its capacity, and the formation strong current generator, because only the capacity with a monomer current transformer is suitable for the capacity of automatic coupling voltage regulator, the weight of strong current generator is alleviated greatly, thereby can realize the integrated of equipment, bring convenience for the use of strong current generator, and the cost of equipment and energy consumption are reduced.
