Comparison of the advantages of vacuum circuit breakers and oil circuit breakers

1. Maintenance cost

Compared with oil circuit breakers, vacuum circuit breakers have lower maintenance costs. Because the operating mechanism of vacuum circuit breakers is relatively simple, the operation is reliable, the structure is simple, and the maintenance is very convenient. At the same time, oil circuit breakers need to replace insulating oil from time to time, which increases the difficulty and cost of maintenance and operation.

2. Safety

Compared with oil circuit breakers, vacuum circuit breakers are safer. Because vacuum circuit breakers are vacuum-encapsulated inside, they do not pollute the environment, eliminating the potential safety hazards such as fire and explosion in oil circuit breakers. Oil circuit breakers need to use insulating oil to block the possibility of combustion or explosion caused by contact between oxygen and oil. Once the insulating oil leaks, it will cause environmental pollution and threaten human health.

3. Environmental protection

Compared with oil circuit breakers, vacuum circuit breakers are more environmentally friendly. Because vacuum circuit breakers do not need to use insulating oil, the situation of oil circuit breakers causing environmental pollution due to oil leakage is avoided. The insulating oil in the oil circuit breaker is inevitably leaked during use, and its emissions will have an irreversible impact on the environment.

4. Reliability

Vacuum circuit breakers are more reliable than oil circuit breakers. Since vacuum circuit breakers are fully enclosed, there are no impurities in the vacuum, which avoids failures caused by oxidation, contamination of insulating oil, impurities generated during the process, etc. in oil circuit breakers. At the same time, vacuum circuit breakers have fast operating speeds and higher short-circuit current carrying capacity, and are more reliable.

In summary

vacuum circuit breakers have greater advantages than oil circuit breakers, with low maintenance costs, high safety, good environmental protection, and strong reliability. Therefore, in modern power systems, vacuum circuit breakers are a more superior choice.
