Description
Technical field:
The present invention relates to a kind of armored conductor metal ceramic insulator electrical penetration.
Background technology:
China has obtained larger development in the nuclear energy field in recent years, and also will obtain larger development, and for safety requirements, every nuclear reactor must be equipped the electrical penetration that quantity does not wait, model is different.In the nuclear power plant that China builds, the electrical penetration major part is by offshore company, and for example French AUXITROL company produces.According to " npp safety shell electrical penetration " national standard (GB13538-92) of China State Bureau of Technical Supervision issue, China ratifies the design of two companies, manufacturing safety without electrical penetration in January, 2009, and does small lot batch manufacture.This two company is respectively Shanghai Power Equipment Research Institute and Chinese Nuclear Power Design Academy reactor engineering research institute.The electrical penetration of above these home and abroad manufacturers produce is similar technically; Adopt organic material, make the insulated enclosure filler of conductor such as poly-vinegar imines, polysulfones, polyether-ketone etc., reach sealing with the technique of swaging, the conductor assembly end is connected with flange with ferrule structure and seals, with metal and ceramic phase ratio, the anti-rung of organic material shines, anti-glutinous change, high temperature resistant grade is all lower, equal defectiveness aspect life-span and fail safe, and the living factory complex process of this electrical penetration, rate of finished products is lower, involves great expense.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of armored conductor metal ceramic insulator electrical penetration, formed by metal ceramic 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 lower useful life at reactor environment.
Technical solution problem of the present invention adopts following technical scheme:
Armored conductor metal ceramic 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 side by side many with armored conductor, the two ends of each described armored conductor are passed respectively flange 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 armored pipes middle part at described armored conductor is socketed with earthenware, front metal sealing pipe box is contained in outside the front end and armored pipes of described earthenware, and rear metal sealing pipe box is contained in outside the rear end and armored pipes of described earthenware.
Design feature of the present invention also is:
Described armored conductor heart yearn is plain conductor, and armored pipes is 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 armored pipes, sealed with brazing between the end face of earthenware and the end face of armored pipes; Described rear metal sealing pipe box is contained in outside the rear end and armored pipes of described earthenware, sealed with brazing between the end face of rear metal sealing pipe and earthenware and the armored pipes.
Has step surface between described earthenware front end and the described armored pipes and with sealed with brazing; Also has step surface between the front end of described earthenware and the described front metal sealing pipe and with sealed with brazing; Sealed with brazing between the end face of described front metal sealing pipe and the end face of described armored pipes.
Compared with the prior art, beneficial effect of the present invention is embodied in:
The metal armouring conductor is at naked copper heart yearn (or thermocouple wire) outer cladding metal armouring pipe, enriches MgO or Al between heart yearn and armored pipes
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 having adopted the metal armouring conductor, adopt metal solder not use organic material namely 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, since simple in structure, process, cost is low, is applicable to reactor, nuclear facility, poisonous, harmful high temperature and high pressure containers or equipment.
