Description
Technical field
The present invention relates to a kind of cable, more particularly to a kind of instrument cable for nuclear power station component, it is adaptable to nuclear power station instrument
Signal transmission.
Background technology
A lot of signal cables are used in nuclear power station, wherein have high requirement for transmitting heap in-core, comprising high temperature resistant, resistance to
Irradiation, moisture-proof, chemical stability etc., newest third-generation technology nuclear power station also requires the service life of 60 years.Existing tradition
Nuclear power station signal cable be organic plasticss cable or organic rubber cable（Hereinafter referred to as organic cable）, this cable has following
Weakness：Catabiosis can occur in the presence of a harsh environment, As time goes on the insulating sheath of cable can occur various slow, no
Reversible chemically and physically change, the tensile strength for showing as material weakens, and hardness increases, and electric property changes；Secondly organic
The heatproof of plastic cable is generally all than relatively low, and the universal heatproof of the cable organic material applied in nuclear reactor at present is all 20
Less than 0 DEG C, it is impossible to using hermetic electrical cnnector（Because fully-sealed electric air connector needs the welding using high temperature）,
So easily causing cable in hot and humid environment, water or water vapour are easily accessible inside cable, so as to cause cable
The huge fluctuation of performance is even failed.
Nuclear power plant equipment also needs to meet there is loss of-coolant accident (LOCA) in nuclear power station（LOCA）After can normal operation, LOCA occur after,
The inside waterpower of pressure reduction, jet-action power and primary Ioops occurs so that cable bears great impact power；Temperature liter in containment
Height, humidity increases, and changes cable work condition；Due to the release of primary Ioops coolant during dehydration so that containment radioactivity
Level also significantly can be raised so that the working environment of cable deteriorates.Under loss of-coolant accident (LOCA) operating mode, cable can be in such a case
Reliability service, and need by testing and identifying.
Cable also needs to meet the shockproof requirements of safe shutdown earthquake, can holding structure and fully functional under seismic (seismal
Property, and need by testing and identifying.
Existing cable is difficult by LOCA, seismic test and identification.
Content of the invention
The technical problem to be solved is：A kind of instrument cable for nuclear power station component is provided, existing to solve
Cable in nuclear power station use, easily do not grow, be difficult by the problems such as LOCA, seismic test and identification by failure, service life.
The technical solution adopted in the present invention is：A kind of instrument cable for nuclear power station component, including flexible bellow, is through
The cable of one or more different size in flexible bellow and electrical cnnector, cable two ends connect electrical cnnector；
The cable includes shell and heart yearn, and it is conductive material that its shell is stainless-steel seamless pipe, heart yearn, fills out between shell and heart yearn
Insulant is filled, insulant is MgO or SiO2Or Al2O3Powder, shell, heart yearn and insulant three are after drawing, annealing
Become flexible entirety；The electrical cnnector is the structure of contact pin or jack, and its shell is made by stainless steel, cable core
The contact pin of line and electrical cnnector or jack are fixed by the way of welding, the glass sintering closure sealing of cable two ends.
Type according to transmission signal is divided into thermocouple signal cable and neutron detector signal cable, thermocouple signal electricity
Cable core wire material is thermocouple thermo wires, and neutron detector signal cable heart yearn material is copper cash or other low resistance conductors；According to
The quantity of transmission signal can be divided into 1 core, 2 cores and multicore.
Cable assembly can be divided into three types according to different effects：
The first kind：A plurality of cable is through in a corrugated tube, and corrugated tube two ends respectively arrange an electrical cnnector, electrical cnnector
Pin number identical with cable core number.
Equations of The Second Kind：Transition joint is provided with, and transition joint one end connects a corrugated tube, and a plurality of electricity is installed with the corrugated tube
Cable, the transition joint other end connects multiple corrugated tubes respectively, is respectively installed with a cable in each corrugated tube, and each corrugated tube is respectively
Connect respective electrical cnnector.
3rd class：One cable is through in a corrugated tube, and corrugated tube two ends respectively arrange an electrical cnnector.
Above-mentioned three types can be independently operated, and can also be applied in combination.
The invention has the advantages that：1st, cable jacket adopts stainless-steel seamless pipe, cable strength is good, fire-retardant,
High temperature resistant, resistance to irradiation, moisture-proof, chemical stability are good, long service life.2nd, filling mineral matter insulation material between shell and heart yearn
Material, insulation resistance is high, dielectric strength is high, high temperature resistant, is higher than 1 × 10 under insulation resistance room temperature11Ω, in 200 DEG C of insulation resistance height
In 1 × 109Ω.3rd, cable outer layer is provided with corrugated tube, protects cable not destroyed by external force, a plurality of cable can be integrated into one
Rise and be connected in an electrical cnnector, make the cable assembly of different size.4th, electrical cnnector adopts stainless steel casing
And welded with cable and corrugated tube so that whole cable assembly degree of protection highest can reach IP68；Intensity is more preferable, electricity
Air connector and cable are without departing from meeting the requirement of seismic test and identification.5th, the method envelope of cable two ends glass sintering
Stifled sealing, can seal under more than 210 DEG C of high temperature, so that steam is not entered in cable, the high insulated electro in the school of holding cable
Resistance, and the organic gel sealing being usually used is that do not possess the sealing property under high temperature.In sum, the present invention can meet LOCA,
Seismic test and identification are required, and can meet the third-generation technology nuclear power station service life of 60 years.
