Description
Technical field
This utility model relates to a kind of earthing detection cabinet for polycrystalline silicon reduction system.
Background technology
When using Siemens Method to carry out reducing polysilicon, owing to silicon rod is electrical body, body of heater is metallics, and therefore body of heater to insulate with silicon rod.And during polycrystalline silicon growth, reduction furnace wall may be touched, so that adhering to one layer of pSi powder on insulator, owing to polysilicon is quasiconductor, resistivity can drastically reduce along with the rising of temperature, therefore insulation is had destruction.And temperature determines polycrystalline silicon growth speed, directly influencing the economic interests of production of polysilicon manufacturer, the traditional manual measurement of described dependence cannot meet the needs of production.
Therefore, develop a kind of detection speed fast, the earthing detection cabinet that accuracy of detection is high, become the problem needing solution badly for insider.
Utility model content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of earthing detection cabinet for polycrystalline silicon reduction system, solve above-mentioned technical problem.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of earthing detection cabinet for polycrystalline silicon reduction system, including cabinet, detection resistance it is provided with in described cabinet, one end of described detection resistance is connected with polysilicon rod by wire harness, and the other end ground connection of this detection resistance, described detection resistance is connected by mutual induction coil transformer, and described transformer is connected by wire harness testing circuit.
Further, described testing circuit connects man-machine interactive system by wire harness.
The beneficial effects of the utility model: electric leakage reference record is uploaded to man-machine interactive system, it is to avoid loaded down with trivial details measurement, reduce cost of labor；System intelligent, automatically screens electric leakage type, and the problem that there is hidden danger is pointed out with alarm form, if this problem continues deteriorate and reached ultimate value, system can be cut off the electricity supply with the protection person and the safety of equipment.Therefore greatly simplified in system operation；This equipment can assist chemical process people finder's technological problems, technique of filling a vacancy leak, therefore improves production efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained, broadly fall into the scope of this utility model protection.
As shown in Figure 1-2, a kind of earthing detection cabinet for polycrystalline silicon reduction system, including cabinet, detection resistance 1 it is provided with in described cabinet, one end of described detection resistance 1 is connected with polysilicon rod by wire harness, and the other end ground connection of this detection resistance 1, described detection resistance 1 is connected by mutual induction coil transformer 2, and described transformer 2 is connected by wire harness testing circuit 3.
Wherein, described testing circuit 3 connects man-machine interactive system 4 by wire harness.
Understand technique scheme of the present utility model for convenience, below by way of in specifically used mode, technique scheme of the present utility model is described in detail.
nullDescribed detection resistance 1 is arranged electrode with the N of polysilicon rod and is electrically connected，When because of attachment polysilicon, resistance declines in insulation，Can drastically become big by the electric current of detection resistance 1，Thus cause the curent change of mutual induction coil，Curent change is transferred to testing circuit by described induction apparatus，Curent change is analyzed by described testing circuit，And analysis result is sent to man-machine interactive system，When polysilicon generation deposition causes curent change，Described man-machine interactive system will send alarm and notifies that technologist carries out the adjustment of technique，When increase in current to ultimate value，Described man-machine interactive system will disconnect the power supply of reduction furnace immediately，Ensure the safety of the person and equipment，In addition when reduction furnace is when occurring " power-off " or " power down "，Described man-machine interactive system will be reported to the police，And block reduction furnace，Prevent because reduction furnace occurs " power-off " to can't detect electric leakage and rebuffed fault，When reporting to the police or after block，To automatically begin to when alarming value is less than 0.9 times of alarming value reset，Block value can hand-reset less than during 0.9 times of block value，Described detecting box can also connect industrial computer，Described industrial computer is used for drawing leakage current numerical curve.
In sum, by means of technique scheme of the present utility model, electric leakage reference record can be uploaded to man-machine interactive system, thus avoid loaded down with trivial details measurement, reduce cost of labor；Intellectualizing system can be utilized; automatically screen electric leakage type, and the problem that there is hidden danger is pointed out with alarm form, if this problem continues deteriorate and reached ultimate value; system can be cut off the electricity supply with the protection person and the safety of equipment, thus simplifies system operation；Chemical process people finder's technological problems, technique of filling a vacancy leak can be assisted, thus improve production efficiency.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
