NOYAFA Electronic specializing in testing instruments and cable testers for 16 years
Cables have a very important role in our daily lives, which works on load carrying electricity. How important is electricity, I want everyone to know, for modern people, no electric work life is working properly, the importance of the cable does not have a very important role in our daily lives, it plays The role of carrying electricity. How important is electricity, I want everyone to have a deep understanding, for modern people, there is no electric work life, and the importance of the cable is not allowed.
However, the cable is used for a long time, it will inevitably fail, let the cable fault detector manufacturers bring some common sense to everyone. As we all know, the cable insulation layer is low, and the current is very large during the full running process, there is a significant feature after a common fault, and the actual classification is as follows: a class of common faults: cable blows or a certain phase burning, such Common faults lead to current relay failures on the distribution box, cable damage is more serious. Second Category Common Fault: The cable is short-circuit faults in each of the cables, and such faults generally cause current relays and voltage relays on the distribution box to work at the same time, the cable is also very serious in general failure points (probably an external force Resulting in).
Three categories common faults: cable can only be single-phase short-circuit, current relay position, common fault damage, but it is obvious. This may be due to the high voltage voltage, or due to the quality of the cable. Four categories common faults: short-circuit faults in the cable, the surface can not be visible, which is generally due to the quality of the wire, is relatively rare.
The range finder and probe fusion applications in common faults in the cable are very convenient. In addition, for different common fault features and cable wires can also be detected separately. Cable fault detector manufacturers sorted the following: a class of common faults and two common faults assume that the cable can be applied immediately below 500 meters to apply common fault probes to the precise positioning of common faults, and do not have to use the rangefinder to cooperate with each other.
As long as the handheld receiver walks into the relative path (the relative path can be tested while taking edges), a common fault point can be determined. Three categories common faults: Since the cable is too damaged in a common fault point, the data signal issued by the transmitter is less leakage, and the detector is often fault. Test the position of the common fault point, then use the rangefinder to perform precise positioning, and then use the rangefinder to perform precise positioning. Four types of common faults: Such common faults are one of the difficulties in all cable faults at this stage. At this time, the cable can be detected on both edges of the cable, and then take the test results and the specific length. The cable can be sawed (because the cable is very cheap, the insulating layer is low, the connection head is good), or use the detector to select the audio locator here for a period of time, and clearly see the fault point.
At present, many power engineering cable fault detector users are used."Flash jump method"As the basic cable fault detector, when the common fault of the cable is treated with a common fault, the gear displacement is commonly used, and the spacing gauge is generally used to roughly measure the spacing of common fault points (the spacing detection of this type of common fault point does not need Use accelerometers to determine the relative path of the cable, in general, it is not necessary to measure the range finder. The above is the dry-saving sharing of cable fault detector manufacturers, hoping to bring some help to people need.
