1. General description ZN83 VCB vacuum
circuit breaker is a new type of indoor medium voltage switch
device, which is mainly used in a three-phase AC power system with
a rated voltage of 12kv, and a rated frequency of 50-60Hz. It has
the advantages of a compact structure, high reliability, small
operation vibration and easy maintenance. It can be widely used in
power plants, steel plants, metallurgy, petrochemical,
transportation, building and other industrial and mining
enterprises as a switch device for protection of high voltage
motors, transformers,line faults and other loads. 2. Product
characteristic Taking different functional units as the
dividing line to realize the modular design. The
integrated and optimized design minimizes the intermediate
realization link of the functional unit, and the overall mechanism
only has more than 70 parts. There is no adjustment
link in the mechanism to minimize the professional requirements for
maintenance personnel. The whole series of products are
easy to operate. Small mechanical operation
vibration. Mechanism with manual energy storage
handle. Fast replacement of wearing parts without
special tools. The whole series of mechanisms have
passed the verification of 72 hour salt spray test. 3.Simple
and reliable structure Less closing interlocking
parts, convenient integrated installation, effective prevention of
false closing. The opening adopts friction type
structure, with small wear and failure rate, so as to improve
mechanical life.4.Main technical parameterCabinet
