Xzh Test 0-220kv Cable Test Van Underground Cable Fault Location System

Product Description

 

Customized 380V-220kV underground cable fault test vehicle

Product Description

With the increasing number of cable applications, the probability of cable failures is also on the rise, and the faults are diversified, such as high resistance, flashover faults, "dead ground" faults, etc.;
 

There are also some unforeseen reasons such as external force operation or manufacturing in the cable construction process, which makes the cable hidden dangers of failure before it runs. If you fail to find out in time and take appropriate repair measures, the defects will continue to develop and may cause equipment insulation breakdown accidents, which will cause equipment damage and bring huge losses to the country.
 

In order to discover equipment defects in time and eliminate accidents in the bud, our country currently mainly adopts preventive tests. Preventive test is an important link in the operation and maintenance of power equipment, and it is one of the effective means to ensure the safe operation of power equipment. Therefore, how to quickly, safely and accurately complete the preventive test work has become a major subject of attention and research of testers. At the same time, the rapid detection of power cable faults has also become a topic of great concern to the relevant departments of the power system.
 

With 20 years of research and development experience, Xi'an XZH provides a complete set of cable testing and cable fault location systems for power cable users. XZH cable test vehicle is our company's on-board cable test system, with high safety factor and comfortable operation.
 

The cable fault detection test vehicle can perform conventional cable test, fault test, and location. Due to the most advanced measurement methods and industrial computer centralized control, the system is easy to operate and powerful. There is no cable that cannot be detected, and there is no problem that cannot be solved on-site. The XHDLJC system can also be customized for users according to different applications.

 

 

We can provide the whole vehicle and the on-board system, or we can provide the on-board system separately. In other words, if you have your own test car, just send us the space dimensions and tell us what you want to test, and we can tailor it to your needs.

Function of the system
1. Use the principle of traveling wave reflection to conduct rough measurement of the main insulation faults of all types of cables
2. Use the Acousto-Magnetic Synchronous Method to perform precise measurement of all types of cable main insulation faults
3. Use the principle of bridge balance to conduct a rough measurement of the sheath fault
4. Use the step voltage method and the clamp current method to accurately locate the sheath fault
5. Conduct AC withstand voltage test (0.1Hz) on power cables of 35kV and below
6. Use the audio method to directly locate the low-voltage cable fault
7. Use the principle of electromagnetic induction to accurately find the unknown cable path and depth
8. Use the phase method to identify multiple cables
9. Use the remote-control method to confirm the final damage to the cable.
