Today, Shenzhen cable fault tester manufacturer Noyafa Electronics will talk to you about whether different cable fault detectors can detect faults. For different cable fault problem points, can cable faults be detected by using detectors? For general cables, Shenzhen today Cable fault tester manufacturer Noyafa Electronics will talk to you about whether different cable fault detectors can detect faults. For different cable fault problem points, can the use of detectors detect cable faults? For general cable faults , the most important thing is a specific requirement based on a formal requirement based on practical considerations. As an analysis of a thinking aspect of the main cable faults, the most important thing is based on an analysis requirement of some main cable faults A specific description of the aspect summarizes the overall construction value in terms of such an overall construction thinking line, a main consideration in the use of the detector, and a main value requirement in the form of specific details. Then, from the perspective of a detection requirement for such a cable fault, usually a main consideration in the form of overall details, a detection requirement in terms of historical relics, and an overall construction idea, the most important thing is that according to different cables. A consideration result in the form of a detail of the main consideration aspect is presented, and a consideration result in the form of a main detail aspect for such a consideration aspect is presented. The main value in terms of a main consideration in terms of being a detailed form of common cable faults is the line of thinking in terms of overall value thinking in terms of such overall detection, and a later detection for such considerations From the point of view of requirements, this is a requirement of detection as the main consideration at present. For a specific analysis of such a detection form, this is a very important consideration and analysis.

Considering a specific analysis above such main thinking directions, a result of a detection aspect of a cable fault problem point for some of these main forms above is shown. 1. The common problem of the line is out of power, and the maintenance posture is skillfully identified; 2. Check the front-end engineer for the quick-break posture, which is about half of the total length; 3. The value of the flow rate is small, and the common problems are far behind; 4. The amount of short-speed overcurrent is the same as the power trip, and the common problem is located in the middle of the line. 5. The area of ​​the line caused by the safety production accident is different, and the posture of the relay protection device is different.

Electric water output interruption maintenance attitude trip: Electric water output interruption generally causes short-circuit faults in the large operation mode of the system. When short-circuit faults are common faults, the maintenance level is large, accounting for about 50% of the total length of the line. When the line is in the small operation mode, the maintenance level is small, accounting for 15% to 20% of the total length of the line. Therefore, the attitude tripping of the electric water output protection device indicates that the common problem is generally located in the front-end development of the line (near the distribution station side).

6. Overcurrent flow maintenance The attitude tripping of the machine and equipment: the maintenance level of the overcurrent total flow maintenance is 100% of the line being maintained. However, in general, overcurrent maintenance machines and equipment are also equipped with time-delay relays. When used in conjunction with quick-break protection devices, attitude trips are generally only caused when common problems are caused in the rear of the line. 7. Maintenance and maintenance of electric water output interruption and overcurrent flow maintenance In addition, attitude tripping: This kind of situation generally indicates that the common problem points are located at the mutual level of quick-break maintenance and overcurrent flow maintenance, and most of the common problem points are located in the middle of the line.

Difficult problems After the knife switch of the distribution station trips, immediately investigate the posture of the relay protection device. According to the posture type and characteristics of relay protection equipment and equipment, the characteristics and levels of common problems are preliminarily agreed.
