3D Impact Recorder Protects The Transportation Safety of High-voltage Switches

Case details: 3D impact recorder protects the transportation safety of high-voltage switches

Customer name: Electric Power Equipment Co., Ltd.

Application scenario: 110kV high-voltage switch cross-border land transportation (China-Central Asia)

Pain points and challenges

• Frequent cargo damage disputes

The internal insulating porcelain bottle and spring mechanism of the high-voltage switch are easily damaged by impact. After the arrival, they were found to be broken when unpacked, but the logistics party and the customer blamed each other, and the average annual dispute cost exceeded 800,000 yuan.

• Traditional monitoring blind spots

Ordinary recorders only monitor single-axis impact and cannot capture the common "tilt drop + lateral extrusion" composite impact scenarios in transportation.

• The cross-border transportation environment is complex

The equipment needs to withstand -30℃ low temperature and sand and dust invasion when passing through the bumpy sections of the Gobi Desert and violent loading and unloading at the border ports.

Solution

• Equipment deployment:

Installation location: top of high-voltage switch body and bottom of transport bracket (double-point monitoring)

Customized parameters:

Range 0.5g~300g (adapted to porcelain bottle micro-crack threshold)

IP66 protection + explosion-proof shell modification (to deal with dust and border security X-ray irradiation)

Data service:

Automatically generate Chinese and Russian bilingual versions of the "Transport Impact Traceability Report" (including GPS positioning map of impact events)

• Implementation process:

Pre-transport prediction:

Based on historical route big data, 3 high-risk sections are marked (Guozigou section in Xinjiang and unpaved roads in Kazakhstan), and it is recommended to reinforce the straps + speed limit.

On-the-way monitoring:

Real-time push of over-threshold alarms (such as 11.7g lateral impact detected during loading and unloading at Alashankou Port, immediate remote guidance of unpacking and random inspection).

Determination of responsibility upon arrival:

Through three-dimensional impact vector analysis, it is proved that a certain insulator fracture was caused by a 26.3g 45° oblique impact during transportation, not a factory assembly problem.
