The all-solid-state converter provided by the utility model has a very high application value in electric heating machining equipment such as welding equipment, a resistance furnace, a salt-bath furnace, electric riveting equipment and electric upsetting equipment; the purpose of three-phase balance power supply can be effectively achieved; and energy conservation and consumption reduction can be realized.
Description
Technical field
The utility model relates to a kind of electric component, particularly all solid state transducer.
Background technology
At present, the heater that the welding of China, resistance furnace, salt bath furnace, rivet weld connect with use such as electric upsetting all adopts single-phase high-power transformer directly to heat, and causes the uneven power supply of three-phase electricity when implementing big current flow heats.If the capacity of previous stage power supply and the difference of single-phase load are not very big, bring the threephase load imbalance problem then will inevitably for the power transformer of previous stage; If the degree of unbalance of threephase load is bigger, to produce such as transformer loss increases, reduce capacity allowable, the problems such as useful life of three-phase output voltage imbalance and shortening transformer, thereby cause other lathe and electric equipment to stop production or damage, greatly influenced operation operation and production management.And the many employing manual operationss of existing operation, heat energy is wayward, causes processing percent defective height, the quality instability, and high material consumption, power consumption is many.
The utility model content
Technical problem to be solved in the utility model provides a kind of energy precise control, can realize the three-phase equilibrium power supply, all solid state transducer of easy to operate and low cost of manufacture.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of all solid state transducer comprises three groups of power electronic equipments, the drive unit that electrically connects with the input of described three groups of power electronic equipments respectively, and the output of described three groups of power electronic equipments constitutes the single phase power supply circuit.
Preferably, the output of described three groups of power electronic equipments adopts the Y-connection mode to constitute the single phase power supply circuit.
Preferably, the input of described drive unit and three groups of power electronic equipments electrically connects by lead.
Preferably, described three groups of power electronic equipments are installed on the radiator.
All solid state transducer of the present utility model connects with electric heating process equipment such as electric upsetting at welding, resistance furnace, salt bath furnace, rivet weld has very strong using value, effectively solves the three-phase equilibrium power supply, realizes energy-conservation, lower consumption.
Its characteristic of the utility model is by the working procedure of regulating drive unit or changes the drive unit input characteristics and then change the voltage or the frequency characteristic of single-phase output.
The output of all solid state transducer of the utility model can insert resistive load, inductive load and capacitive load.
Description of drawings
The user mode figure of all solid state transducer that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
From the utility model execution mode shown in Figure 1 as can be known:
All solid state transducer of the present utility model comprises three groups of power electronic equipments 2, the drive unit 1 that electrically connects with the input of three groups of power electronic equipments 2 respectively, the output of three groups of power electronic equipments 2 can adopt the Y-connection mode to constitute the single phase power supply circuit, also can adopt the triangle connected mode to constitute the single phase power supply circuit.
The input of drive unit 1 and three groups of power electronic equipments 2 electrically connects by lead, also can adopt the mode of other electric connections, as drive unit 1 and three groups of power electronic equipments 2 are installed on the printed circuit board.
Because three groups of power electronic equipments 2 in use can produce a lot of heats, therefore be necessary described three groups of power electronic equipments 2 are installed on the radiator 3.Certainly, also can adopt other radiating modes, as dispelling the heat by fan.
In use, the standard three-phase alternating-current supply can be connected one to one with three groups of power electronic equipments 2 respectively, as shown in Figure 1, A, B, C are the power supply of standard three-phase alternating-current supply, so respectively organize alternate Uab, Uac, Ubc, Uba, Uca, the Ucb of just having formed, totally 6 groups of synchronous cosine wave curves.Every group of power electronic equipment 2 is divided into two parts, and a part is the positive direction path, and another part is the opposite direction path.In first group of Uab, Uac, Ubc, Uba, six cosine wave curves of Uca, Ucb, a is the positive direction path among the Uab, and b is the opposite direction path; A is the positive direction path among the Uac, and c is the opposite direction path; B is the positive direction path among the Ubc, and c is the opposite direction path; B is the positive direction path among the Uba, and a is the opposite direction path; C is the positive direction path among the Uca, and a is the opposite direction path; C is the positive direction path among the Ucb, and b is the opposite direction path.Control the positive direction path of power electronic equipment 2 among A, B, the C and path in the other direction respectively by drive unit 1, just formed first group of single-phase output.Rationally control by drive unit, can realize first group of ripple, second group of ripple, the 3rd group of ripple ... control, finally just formed continuous single-phase output function, single-phase output circuit can insert resistive load, inductive load and capacitive load.
By changing forward path and the time of backward channel or voltage and the frequency that frequency just can change unidirectional output.
In sum, content of the present utility model is not limited in the above-described embodiments, and those skilled in the art can propose other execution mode easily according to guiding theory of the present utility model, and these execution modes all are included within the scope of the present utility model.
