Compared with the prior art, the special-purpose inverter power supply for the skin effect cable can lead a skin heating system to be in a best work state, has high energy using and obvious energy-saving effect, and increases the electro thermal conversion efficiency of a skin system because of using higher frequency.
Description
Technical field
The utility model relates to a kind of power supply, specifically provides the special-purpose variable frequency power supply of a kind of kelvin effect cable.
Background technology
Under the prior art, for the use of kelvin effect cable, it is general direct, and these power supplys not only make the cable job insecurity, and supply frequency is low by transformer connection common power, and the electric conversion efficiency of collection skin system is also very low.
Summary of the invention
The utility model is at above problem, provide a kind of kelvin effect cable special-purpose variable frequency power supply, realize the continuous adjusting of output voltage, electric current, to reach the continuously adjustable purpose of power output, outputs such as use digital display temperature controller carry out closed-loop control to power supply, make collection skin heating system be in optimum Working, the using energy source height, energy-saving effect is obvious, owing to adopted higher frequency, the electric conversion efficiency of collection skin system improves.
The technical scheme that its technical problem that solves the utility model adopts is:
The special-purpose variable frequency power supply of a kind of kelvin effect cable comprises central processing unit, and central processing unit one end connects the three-phase alternating current electrical input by inverter circuit, and the other end connects display part, movement and output by control bus.
Central processing unit also is connected with the measurement Acquisition Circuit.
The special-purpose variable frequency power supply of kelvin effect cable of the present utility model, with third generation IGBT high-power switch device is main circuit, 8 special-purpose central processing units with the advanced person are control assembly, constituted a complete control system with the digital display temperature controller, equipment performance is good, reliability is high, the operation is particularly easy.
The special-purpose variable frequency power supply of kelvin effect cable of the present utility model also has following characteristics:
1, central processing unit is that special-purpose single-chip microcomputer is the height integrated chip, and there is microprocessor its inside, because volume is little, function is strong, makes it obtain extensive use at aspects such as instrument, computer peripheral, process control and Industry Control.So it has very strong adaptive capacity to environment and antijamming capability, reliable operation, advantages such as life-span length.
2, the display part is a man-machine dialog interface, and group of four figures pipe shows can show operating current and frequency, pulse duty factor, electric current running parameter etc. by the selection of button, and can show malfunction.
3, movement is taked forced air cooling, and advanced third generation IGBT power model is adopted in the DC/AC conversion, and general structure is reasonable, and is easy to maintenance.
4, output adopts annular intermediate frequency transformer, be used for isolating input, output high pressure, be connected with control cubicle output through capacitance group simultaneously, play every straight effect, the magnetic saturation problem that D.C. magnetic biasing or overexcitation produce prevents owing to can play the effect of series resonance simultaneously.
Intermediate frequency transformer is an amorphous titanium material, the permeability height, and the operating frequency height, the self-energy loss is extremely low, so overall efficiency improves greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the special-purpose variable frequency power supply of kelvin effect cable of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the special-purpose variable frequency power supply of kelvin effect cable of the present utility model is further described.
As shown in Figure 1, the special-purpose variable frequency power supply of a kind of kelvin effect cable comprises central processing unit 1, and central processing unit 1 one ends connect three-phase alternating current electrical input 3 by inverter circuit 2, and the other end connects display part 5, movement 6 and output 7 by control bus 4.
The special-purpose variable frequency power supply of kelvin effect cable of the present utility model at first becomes the three-phase alternating current of 380V/50Hz (1140V/50Hz) into direct current after rectification, become the single-phase electricity of 260～1000Hz again through inverter circuit 2, after output 7 is isolated, be transported to heating cable again.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection range of the present utility model.
