The assembly comprises a ceramic body (1) inside of which an aperture is cut, in which a resistance subassembly (A) is mounted and is fastened between two micanite plates (2), the resistance subassembly (A) comprising a first micanite support which has a Kanthal D wire wrapped around it and a second micanite support, the ends of the wire being insulated through the two micanite plates (2) in between which the subassembly (A) is displayed, the charging of the electric resistance being effected through two cables (8) with a double thermo resistant insulation (9), the connection of the ends of the Kanthal wire being done in such a way that its noninsulated ends are fastened between the two micanite insulated plates (2), the ceramic body (1) having its filled with a thermo-resistant adhesive.
Description
Technical field
The present invention relates to the resistance that a kind of ordinary temp is heated by resistive assembly and is used for thermal technology, this electric resistance heating assembly is designed to move under the highest 500 degrees centigrade temperature.
Background technology
Current, the known resistance that utilizes ceramic material or Bohemian glass as electrical insulator.Heating element is placed on these ceramic materials inside or is inserted into the hole of passing in the electrical insulator.This quasi-resistance means higher current drain and considers and need make accurately, the process technology difficulty.In addition, heating element may be oxidized because of contacting with air, especially in the common operating time.
From Romanian patent RO 85804, learn a kind of resistance that moves down up to 1000 degrees centigrade in temperature, this resistance comprises that inside has the ceramic body in two vertical holes, heating element is inserted in vertical hole, this heating element vitreous coating, simultaneously also as the tensioning fastening block, the ceramic body end has the cement layer to this glass simultaneously as electrical insulator, temperature transfer block.Be connected with power supply with two copper conductors that fluid glass applies with the part.
From Romanian patent RO 81149, learn another kind of resistance, this resistance comprises the heating element by two copper conductor welding that are connected with control loop, form electric insulation by glass fiber, this glass fiber is reeled and is passed through absorbent core but separated around heating element and around two conductors.In another optional assembly, realize electric insulation by the pipe that fiberglass mesh is made, wherein the end of this pipe is affixed by making the glass thread hot melt.
With regard to building method, already present all heating types are made by two critical pieces on the market: resistance sub-component and be the ceramic body that 30% hygroscopic material is made by porosity.This resistance is reeled with the diameter spiral of 3mm by the line of circular cross section and is made, and with heat insulation husky sclerosis, wherein covers vacant hole with heat-resistant adhesive.Guarantee protection against electric shock by basic insulation.
Hitherto known resistance has the shortcoming that causes thermal loss because of single thermal insulation layer, and these resistance are frangible; Have higher thermal inertia, this means high energy consumption; Has high wet sensitive; Can move the possibility that exists lead to rupture owing to insulating material because of electric shock; When the overlay area of heating element is enough not thick, have because of the wrinkling risk of temperature distortion.
Summary of the invention
Therefore, technical problem to be solved by this invention is the supplementary insulation of conducting parts, protection against electric shock and overcome above-mentioned shortcoming by being configured in the resistance heater that moves under the highest 500 degrees centigrade temperature, this resistance heater comprises that by porosity be the ceramic body that 0% non-hygroscopic material is made, in this ceramic body, the resistance sub-component is placed between two micarexs, wherein resistance sub-component self comprises the first mica strutting piece and the second mica strutting piece, this first mica strutting piece has the KANTHAL D line of reeling around self, insulated by two micarexs in the end of line, power to resistance by two flexible cables with dual heat-resistant insulator, be fastened on the end that two modes between the micarex connect this line by nonisulated end, the heat-resistant adhesive filling of the end of ceramic body with the Khanthal line.
Resistance according to the present invention is used for the thermal technology field and has following advantage:
Dual protection against electric shock (2 class F insulation)
High operational safety
Reduce hot coherence, this means low energy consumption
Good temperature control
Heating element does not contact with air thereby can be not oxidized, and this makes average operating time long
Simple in structure thereby easy assembling, maintenance and operation
Owing to sufficient thermal insulation has high thermal efficiency and high energy efficiency
