概述
PES-132 (ZW32-12) outdoor pole-top high-voltage vacuum circuit breaker is an outdoor high-voltage switching apparatus, which is generally applicable of interrupting and making load current, overload current and short-circuit current in power system. The switch is maintenance-free, adopting vacuum arc extinguishing.
适用范围
It is applicable to protection and control in substation and power distribution system of industrial and mining enterprises and is better applicable to rural power grid and sites of frequent operation. ZW32 pole-top circuit breaker is generally applicable to 10kV overhead line as sectionalizing and boundary switches.
特点
①The circuit breaker is composed of three-phase support type and mechanism chamber, which is simple in structure.
②Current transformer is installed on mobile terminal outgoing line and secondary interface adopts aviation socket, making it convenient to maintain and replace.
③Vacuum arc extinguishing chamber of the circuit breaker adopts technology of solid insulation, which is small in volume, long in service life and high in reliability. Its shield is exposed. It is sealed in epoxy resin, which is convenient for transportation.
④Operation mechanism is novel, simple, and reliable in operation and small in volume whose mechanical life can reach 10,000 times.
⑤Switch enclosure adopts stainless steel processed in spraying plastics, which is of sound corrosion resistance.
⑥It is allowed to be equipped with insulation switch, making a visible break and with reliable interlocking.
⑦It is able to be equipped with distribution terminal, realizing functions of four-remote and feeder automation.
