Do not install automatic machine casing wear bushing accident data analysis

 

Because of the accident continue to enhance national power, so today we analyze Dongguan Yang is not equipped with automatic wear bushing machine casing accident data, please read down:

 

Transformer bushing machine is automatic through the transformer inside the high and low voltage wire lead to the external fuel tank outlet device. As the lead casing for ground insulation, is also charged with the role of fixed leads. Therefore, it must have electrical and mechanical strength requirements. In addition to the long-term because it should withstand the load current during operation, it should also be able to withstand transient short-circuit overheating.

2005 2014 a casing failure data Table 1 Data of fault bushings in 205 to 2014 年
Casing the number of accidents 152l5O44
Casing failure number 6363l0989773l
End screen poorly grounded 24678l7l630 (failure frequency Note)

In 2014 the number of failures in the sleeve casing containing oil leakage 100,000 times. Good thermal stability. If the transformer bushing defects or failure will directly endanger the safe operation of the high-frequency transformer for turtles and reliability. In recent years, running casing accident rate and failure rate uptrend. According to incomplete statistics.
 

Our HY-R20 automatic machine for monochrome wear bushing sleeve, black casing, two-pronged approach, while wearing a black and white casing, single color, two color, two-color, three-color, four-color This product is suitable diameter between 0.1 to 0.7, the number of shares equal to 200 in the rain wearing a sleeve process the following products. Select casing principles: the casing via multi-strand wire diameter ≥ + 0.12mm
