Description
Technical field
The utility model is related to the technical fields of fault detect, more particularly to a kind of cable for Cable fault examination
Sensor and Cable fault examination system.
Background technology
The most immediate cause of cable fault be insulation reduce and it is breakdown；Cause the factor that insulation reduces very much, according to reality
Border operating experience is summed up nothing more than following several situations：
(1) external force is damaged.From the point of view of operating analysis in recent years, the extra large Pudong especially in rapid economic development is existing
All it is caused by mechanical damage in considerable cable fault.Such as：Construction lack of standardization when cable laying is installed, is easy to make
At mechanical damage；Civil construction is done on direct-buried cable also easily by running cable fault etc..Sometimes if damage is not tight
Weight wants even several Nian Caihui some months to cause damage location thoroughly to puncture to form failure, destroy sometimes it is serious may occur it is short
Road failure directly affects the safety in production of electric electricity unit.
(2) humidified insulation.Such case is also very common, typically occurs at the cable connector in direct-burried or comb.Such as：
Cable connector makes unqualified and makees connector under moist weather conditions, and connector can be made to intake or be mixed into vapor, of long duration
Water tree is formed under electric field action, the dielectric strength of cable is undermined and causes failure.
(3) chemical attack.Cable is directly embedded in the area of acid-base function, often cause armature of cable, sheet lead or
Outer jacket is corroded, and because by chemical attack or electrolytic etching, protective layer being caused to fail for a long time, insulation reduces protective layer, also can
Lead to cable fault.
(4) long-term running overload.Overload operation, due to the fuel factor of electric current, load current passes through inevitable when cable
Lead to conductor temp.-elevating, while the kelvin effect of charge and the eddy-current loss of steel armour, insulation dielectric loss can also produce first additional heat
Amount, to make cable temperature increase.When long-term overload operation, excessively high temperature can accelerate the aging of insulation, so that insulation quilt
Breakdown.Especially during the broiling summer, it is breakdown first to frequently result in cable insulation weakness by the Wen Sheng of cable, therefore in summer,
The failure of cable is also just especially more.
(5) cable and junction malfunction.Cable connector is link most weak in cable run, by the direct fault of personnel (construction
It is bad) cause cable and junction malfunction occur often.Construction personnel is during making cable connector, not if there is coupling compression joint
Tightly, the former net such as insufficient is heated, can all cause end insulation to reduce, to cause accident.
(6) environment and temperature.External environment and heat source residing for cable will also result in that cable temperature is excessively high, insulation breakdown,
It is even on fire from explosion.
(7) other reasons such as the normal aging of cable body or natural calamity.
As country increases investment to basic energy resource facility, the completion of two-channel filter banks has run the quantity of cable drastically
Increase, the fast development of urbanization brings the substantial increase of construction project, cable fault is caused to greatly increase.And it is existing in the market
Power cable fault test instrument, it is aobvious stupid, big, numerous although kind is more, it is inconvenient for operation, it is difficult to quickly to grasp.
