Abstract
A high-temp insulated measuring control wire is used for measuring and controlling in high-temperature situations. An insulating layer woven by quartz glass fibre wires is arranged on the composite coating layer outside conductor and the exterior of the woven insulating layer is coated with the composite coating layer. The composite coating layer is in semi-hardening shape, and then becomes inorganic slowly to form ceramic insulating layer under high-temperature function. The wire has the characteristics of soft property, convenient operation and installation, good insulating property at high-temperature, etc. The high- temperature insulated measuring control wire can satisfy the operating requirements of high precision measurement.
Description
The utility model belongs to resistant to elevated temperatures electrical equipment line, makes the high temperature occasion and measures control line usefulness.
High-temperature insulation line commonly used is similar with day clear 57-88619 and the clear 57-88620 high temperature insulation wire structure of disclosure special permission communique introduction.Promptly on conductor, be coated with the high temperature resistant compound inslation coating that one deck is mixed with inorganic particulate by fire resistant resin, during manufacturing after being coated with on the conductor with composite coating sintering wind type standby.This line-transect is harder, uses inconvenience, and insulation resistance descends during high temperature, generally has only 0.1M Ω at 900 ℃ of following insulation resistances.Instructions for use in the time of can not satisfying high-acruracy survey, the insulating capacity when improving such electric wire high temperature.Make electric wire also keep high insulating resistance value when high temperature, and have flexibility preferably, the spy has proposed the utility model.
For finishing the proposed invention task, adopted following technical scheme:
1, weaves the insulating barrier of one deck even compact on the high temperature resistant compound inslation coating outside conductor with quartz glass fibre;
2, outside the quartz glass fibre braid, be coated with the high temperature resistant compound inslation coating of one deck again;
3, earlier composite coating is dried into the semi-solid preparation shape, makes electric wire have flexibility preferably, treat the electric wire laying installation after, borrow use high temperature more slowly heating make inorganicization of coating.Formation has the ceramic-like insulating barrier than high insulating property.
The structural representation of Fig. 1, high-temperature insulation observing and controlling line.
In Fig. 1, (1) conductor, compound inslation coating that (2) are high temperature resistant (abbreviation composite coating), (3) quartz glass silk braid.
Conductor (1) is refractory metal line or alloy lead wire. Such as the nisiloy line. Nichrome wire, stainless steel wire, golden palladium winding thread, pure nickel line etc. all can adopt. High-temp. resisting composite insulation coating (2) is by being to add the coating that inorganic powder and solvent be modulated in the resinoid to make at silicon. Wherein silicon is that resin can be selected silicones or modified silicone resin, and inorganic particulate can be selected aluminium oxide (Al2O
3), barium titanate (BaTiO3), silica (SiO2), the powder such as magnesia (MgO). Namely this coating is semi-harden shape.
The invention will be further described below in conjunction with embodiment:
For realizing that the present invention once was mixed with A, B, three groups of high temperature resistant composite coating samples of C with the silicon rubber and the aluminium oxide of the different trades mark, its component is as shown in table 1:
