Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail。Following example will assist in those skilled in the art and are further appreciated by the present invention, but do not limit the present invention in any form。It should be pointed out that, to those skilled in the art, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement。These broadly fall into protection scope of the present invention。
Embodiment
Referring to accompanying drawing 1, heater power unit 10 includes temp controlled meter 1, solid-state voltage regulator 2, heater 3 and temperature sensor 4, heater 3 is installed in and preheats in product, one or more temperature sensor 4 is set in the relevant position of product, temp controlled meter 1 electrically connects with temperature sensor 4, temp controlled meter electrically connects with solid-state voltage regulator 2, solid-state voltage regulator 2 is supplied to heater 3 and heats to product after being regulated by output power, by the target heating temperature to temp controlled meter 1 pre-set product, temperature sensor 4 sends the actual temperature of product to temp controlled meter 1, after actual temperature and preset temperature are contrasted by described temp controlled meter, built-in pid algorithm through temp controlled meter, control solid-state voltage regulator 2 and export different power to heater 3, make the temperature remained constant of described product。Temp controlled meter 1 selects AI708 temp controlled meter, and the target temperature of temp controlled meter 1 is set and can be arranged by remotely controlling computer or local manually setting。
Referring to accompanying drawing 2,3,2 to 8 heater power unit 10 are grouped together into supply module 20,2 to 8 supply modules 20 are grouped together into multichannel heating installation power supply system again, and the power cabinet 30 being provided with this multichannel heating installation power supply system is equipped with power module 31 to the heating offer high power stabilized power source of product。Power module 31 will obtain the alternating current of 126V by 3 phase transformer after 380V alternating current transformation。In use, selecting 4 power supply units 10 are formed a supply module 20, supply module 20 can be used alone。May select and 4 supply modules 20 are formed a switch board 30。The power supply of heater is all individually controlled by a road temp controlled meter by so each road, substantially increases reliability。Individually carry out temperature control, be individually powered controlling, mutually do not interfere with between each road。The present invention uses the cheap temp controlled meter of heating to realize closed loop thermal control。The capacity of one road power supply can reach more than 2000W。In use, can be installed in rack by little electric supply installation combination centrally connected power supply；If desired, it is possible to disperseed to use。
Invention introduces controlled Alternating Current Power Supply voltage regulating module system, it is provided that the high-power power supply no less than 2000W of every road power。Have employed Distributed Design, each road powers a corresponding road voltage regulating module, and this road voltage regulating module is only controlled by again the intelligent temperature control table on this road, thus can realize quickly response and high reliability。The common module based on programme-controlled dc power to carry out output computing by the control software design of control system, and response speed can only achieve ten seconds levels；Employing the distributed control mode of the present invention, each road powers and is limited only by the control of relevant temp controlled meter, it may be achieved be not less than the quick response of 0.5 second。And, distributed control mode avoids the unified risk using control software design to bring: if all power supplies are all controlled by a control software design, and when control software design or control computer go wrong, all supplying channels all can break down。Intelligent temperature control table corresponding to each road power supply station, all with communication interface, can be carried out configuration by remotely controlling computer and operate。Completed operation by the unified file that arranges, because of and centralized Control can be realized on distributed basis。
