Description
Technical field
The present invention relates to heating cable detection band lamp tail ends.
Background technique
Heating cable fault most immediate cause be insulation reduce and it is breakdown.There are many factor for causing insulation reduced, root
According to practical operating experiences, be summed up nothing more than following several situations: 1, external force is damaged.From the point of view of operating analysis in recent years,
Extra large Pudong especially in rapid economic development, present considerable heating cable fault is all since mechanical damage causes
's.Such as: construction lack of standardization when heating cable laying installation be easy to cause mechanical damage；Civil engineering is done on direct-burried heating cable
Construction is also easily by running heating cable fault etc..If damage is not serious, even several Nian Caihui some months to lead sometimes
It causes damage location thoroughly to puncture and forms failure, destroy serious possible generation short trouble sometimes, directly affect electric electricity unit
Safety in production.2, humidified insulation.Such case is also very common, typically occurs in the heating cable connector in direct-burried or comb
Place.Such as: heating cable connector makes unqualified and makees connector under moist weather conditions, and connector can be made to intake or be mixed into water
Steam, it is of long duration to form water tree under electric field action, it undermines the dielectric strength of heating cable and causes failure.3, chemical
Corrosion.Heating cable is directly embedded in the area of acid-base function, often will cause heating armature of cable, sheet lead or outer jacket quilt
Corrosion, because by chemical attack or electrolytic etching, protective layer being caused to fail for a long time, insulation reduces protective layer, also results in heating
Cable fault.4, long-term running overload.Overload operation, due to the fuel factor of electric current, when load current is by heating cable
Necessarily lead to conductor temp.-elevating, at the same the kelvin effect of charge and the eddy-current loss of steel armour, insulation dielectric loss can also produce it is first attached
Heating amount, to make to heat cable temperature raising.When long-term overload operation, excessively high temperature can accelerate the aging of insulation, with
It is breakdown to insulating.Especially during the broiling summer, heat cable temperature rise frequently result in heating cable insulation weakness first by
Breakdown, therefore in summer, the failure for heating cable is also just especially more.5, cable and junction malfunction is heated.Heating cable connector is to add
Most weak link in electric heating cable route is sent out often by the heating cable and junction malfunction that the direct fault of personnel (construction is bad) causes
It is raw.Construction personnel, if there is coupling compression joint is not tight, heats the former net such as insufficient, can during cable connector is heated in production
Cause to heat end insulation reduction, to cause accident.6, environment and temperature.Heat external environment and heat source locating for cable
It will also result in heating cable temperature be excessively high, insulation breakdown or even on fire from explosion.7, the normal aging or nature of cable body are heated
The other reasons such as disaster.
At this stage, all it can not be detected and be examined after most heating cable bad, and after heating cable bad
The problem of consequence is again very serious, and how to realize the detection of heating cable becomes urgent need to resolve at this stage.
