Description
Technical field
The present invention relates to a kind of zero cross fired control system, particularly relate to a kind of zero cross fired control system for melting furnace (electric furnace).
Background technology
Melting furnace is widely used heat energy utilization equipment in industrial production.According to Heating style, melting furnace can be divided into Fuel Furnace and the large type of electric furnace two.China's present stage a large amount of Fuel Furnace that use, its shortcoming is that efficiency of combustion is low, fuel storage inconvenience, gas and liquid fuel are easily blasted and combustion noise etc.And electric furnace is take resistance wire furnace as main, its major defect is resistance wire easy fracture, and service life is short, maintenance difficult, and the low and heat-insulating property of the thermal efficiency is poor etc.
General electric furnace is made up of three parts, i.e. heater element, furnace building material and control device.When the resistance value of the heater element of old-fashioned melting furnace is too little or when resistance change is too large in the course of the work, need a supporting transformer, to reduce and to regulate the output voltage of electric furnace between stove and electrical network.And the larger transformer of capacity is all made separately, bulky, expensive.Meanwhile, temperature regulates and display unit all adopts moving-coil instrument and general electric elements, controls very inconveniently, and error is large.
Therefore, be badly in need of a kind of easy to operate, little control system of error, guarantee the normal work of melting furnace (electric furnace).
Summary of the invention
The object of the present invention is to provide a kind of zero cross fired control system, use in conjunction with electric furnace, realize the function of transformation and voltage stabilizing, can make that described electric furnace is contactless, noiselessness, reliability is high, volume is little, at the bottom of low in energy consumption, price and easy to adjust.
The object of the invention is to adopt following technical scheme to realize.The present invention proposes a kind of zero cross fired control system, comprises voltage changing module, Voltage stabilizing module and display module; Wherein, this voltage changing module is connected with Voltage stabilizing module, and this Voltage stabilizing module is connected with display module simultaneously, and this display module is connected with voltage changing module again.
Object of the present invention can also be further achieved by the following technical measures.
Aforesaid zero cross fired control system, wherein this voltage changing module comprises ZK-03 three-phase zero passage silicon controlled toggle.
Aforesaid zero cross fired control system, wherein this display module comprises display list and thermocouple.
Aforesaid zero cross fired control system, wherein this display list is selected XMT type temperature display watch.
By technique scheme, zero cross fired control system of the present invention can reach suitable technological progress and practicality, and there is the extensive value in industry, it at least has following advantages: the invention provides a kind of zero cross fired control system, use in conjunction with electric furnace, realize the function of transformation and voltage stabilizing, can make that described electric furnace is contactless, noiselessness, reliability is high, volume is little, at the bottom of low in energy consumption, price and easy to adjust.Meanwhile, utilize zero cross fired control system of the present invention to coordinate with electric furnace, can regulate and control electric furnace quick, simple and easy and easily, make the programming rate of electric furnace fast, good heat insulating, and after breakpoint, temperature declines very slow.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, and for above and other object of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
