Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of armored conductor cermet insulator electrical penetration, form by cermet insulator and hardware welding, it is simple and reliable for structure, more ability irradiation, high temperature, chemical corrosion, baked wheaten cake, vibrations, thereby safer, be no less than 60 years following useful life at reactor environment.
The utility model technical solution problem adopts following technical scheme:
Armored conductor cermet insulator electrical penetration comprises interior box and outdoor terminal box, and the two ends of being located at the housing in the wall hole are connected in described interior box and the outdoor terminal box, and the two ends of described housing are respectively equipped with flange seal; In housing, be provided with many side by side with armored conductor, the two ends of each described armored conductor are passed flange respectively and are connected with electric device through interior box and outdoor terminal box, the structure that is in the armored conductor in interior box and the outdoor terminal box is: the armouring pipe middle part at described armored conductor is socketed with earthenware, preceding metallic seal pipe box is contained in outside the front end and armouring pipe of described earthenware, and back metallic seal pipe box is contained in outside the rear end and armouring pipe of described earthenware.
Design feature of the present utility model also is:
Described armored conductor heart yearn is a plain conductor, and the armouring pipe is a metal outer pipe, is filled with MgO or Al between described heart yearn and metal armouring pipe
2O
3Heat-resistant insulating layer.
Welding or sealed with brazing between the perforation of described metal armouring pipe and described flange.
The rear end external diameter of described earthenware is identical with the external diameter of described armouring pipe, sealed with brazing between the end face of the end face of earthenware and armouring pipe; Described back metallic seal pipe box is contained in outside the rear end and armouring pipe of described earthenware sealed with brazing between the end face of back metallic seal pipe and earthenware and the armouring pipe.
Has step surface between described earthenware front end and the described armouring pipe and with sealed with brazing; The front end of described earthenware and described before also have step surface between the metallic seal pipe and with sealed with brazing; Sealed with brazing between the end face of the end face of metallic seal pipe and described armouring pipe before described.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The metal armouring conductor is to coat the metal armouring pipe outside naked copper heart yearn (or thermocouple wire), enriches MgO or Al between heart yearn and armouring pipe
2O
3Heat-resistant insulating layer, metal armouring conductor reach pressure bearing and seal with soldering passing metal flange hole place, reach sealed insulation at end conductor by soldering heart yearn is drawn.
Owing to adopted the metal armouring conductor, adopt metal solder not use organic material promptly to reach the purpose of insulation and sealing, therefore this electrical penetration has higher voltage endurance capability, lower released gas rate, more anti-irradiation, high temperature, life-span is longer, because simple in structure, technology is reliable, cost is low, is applicable to reactor, nuclear facility, poisonous, harmful high temperature and high pressure containers or equipment.
