Wind power cable detection steps for fire cable failure
Release time:
2019-02-13 01:30
1, fire cable fault diagnosis
The diagnosis of the nature of a cable fault is to determine the type and severity of the fault so that the tester can take remedial action and select the appropriate cable fault location and location method.
2, fire cable fault location
Cable fault location, also known as coarse measurement, is used by wind turbine cables to determine the fault distance at one end of the cable. Common fault location methods at the test site include: classical bridge method (high voltage bridge method, low voltage bridge method) and modern traveling wave method (pulse method: low pressure pulse method, high pressure pulse method).
3, fire cable fault location
Cable fault location, wind power cable is also called accurate measurement, that is, according to the fault location result, according to the path of the cable, find the general location of the fault point, in a small range, use radio acoustic method or other methods to determine the exact location , the point of failure.
In general, cable fault detection of Fenghua cable must go through these three steps. Otherwise, it will not be possible to achieve haste. For example, in the absence of a fault location, it is difficult to detect the sound of a fault point with a long cable path (possibly long long miles). If the cable fault distance is known, it is easier to move the fixed point instrument within a small range to detect the cable fault point in a very small range (about 10 meters).
The above is the steps of the Shaanxi fireproof cable fault test introduced by Fenghua Cable. Through these three points, we can better speed up our understanding of cable faults. If you have any questions, please contact us.
