High-voltage zinc oxide arrester, also called high-voltage zinc oxide varistor, has
the advantages of small size, light weight, and good overvoltage protection performance. It is widely used for overvoltage protection in vacuum circuit breaker operation.
(1) Wiring of zinc oxide arrester
The zinc oxide arrester should be connected to the pile head under the circuit breaker and as close as possible to the protected equipment. Its wiring is
shown in the figure. In the figure, FP is a zinc oxide arrester. QF is a vacuum circuit breaker .
