Abstract

The utility model discloses a three-phase double reverse-star rectifier transformer, which can meet various input control requirements and can be easily connected with PLC automation. Besides a transformer and fuses, the rectifier transformer further comprises a power controller and a rectifier, wherein the power controller is mounted between the fuses and the transformer, and the rectifier is mounted at the output ends of the transformer.

Description

Three-phase double reverse-stars type rectifier transformer
Technical field
The utility model relates to commutation technique, relates in particular to a kind of three-phase double reverse-stars type rectifier transformer.
Background technology
In present system lamp industry, the direct voltage that needs low-voltage, big electric current on glass tube heating, the sealing-in stove is as heating source, and this need realize by rectifier transformer.Rectifier transformer is a transformer of specializing in commutation system, is the voltage that exchange conversion is become a certain size and the number of phases, and then through rectifier cell (thyristor) rectification, to satisfy the requirement of direct current output.
As Fig. 1, it is prior art three-phase fully-controlled bridge rectification circuit figure.The alternating current that AC network is come inserts the elementary coiling group of transformer by fuse, through the transformer transformation, ac voltage from secondary rolling thread group input needs, triggered by six thyristor phase shifts and obtain direct voltage, the pilot angle of controlling each thyristor can obtain the size of different direct voltages.The shortcoming of sort circuit is that under powerful state, each thyristor need be installed on the heating panel, and needs enough big heat-sinking capability, so its volume is bigger.The shortcoming of this technology is that under powerful state, each thyristor need be installed on the heating panel, and needs enough big heat-sinking capability, so its volume is bigger.
The utility model content
Technical problem to be solved in the utility model has provided a kind of three-phase double reverse-stars type rectifier transformer, can satisfy multiple input control requirement, is convenient to realize and being connected of PLC automation.
In order to solve above technical problem, the utility model provides following technical scheme:
The utility model provides a kind of three-phase double reverse-stars type rectifier transformer, removes to comprise transformer and fuse, further comprises a power controller and a rectifying installation, and wherein, this power controller is installed between described fuse and the described transformer; This rectifying installation is installed in the output of described transformer.
The utility model by introducing power controller, can satisfy multiple input control requirement with the three-phase double reverse-stars type rectifier transformer that adopts, and is convenient to realize and being connected of PLC automation.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is prior art three-phase fully-controlled bridge rectification circuit figure;
Fig. 2 is the circuit diagram of the utility model one embodiment;
Embodiment
As Fig. 2, it is the circuit diagram of the utility model one embodiment.On the basis of existing technology, access power controller between fuse and transformer, preferred triple-phase thyristor power controller, the model of power controller is determined according to input voltage and input voltage, can satisfy multiple input control requirement, be convenient to realize and being connected of PLC automation.Output at transformer is installed rectifying installation, such as rectifier diode, thereby makes circuit simple, and the every phase current of mean allocation, and it is little to generate heat, and the diode breakdown rate is low, and the entire circuit performance is more stable, the reliability height.In addition, the primary side of transformer is the three-phase delta connection in the utility model, and secondary side is that six phase star neutral points are drawn wiring, and promptly secondary side winding has two, all is connected into star, can eliminating transformer iron core dc magnetization problem.
Above-described is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
