Features
Totally enclosed
poles with excellent electrical performance
The main circuit of
the VSV series vacuum circuit-breaker adopts totally enclosed
structure with either insulated tubular canister or embedded
poles.
a) Insulated
tubular structure
The main circuit
parts are attached vertically in a tubular insulated canister. The
insulating cylinder is made from epoxy resin through advanced AGP
casting technology. Thus it has good anti-arc, anti-aging, and high
strength properties. With such structural design, it prevent the
external effects to vacuum arc extinguish chamber including
external shocks, polluted ambient effectively, improved the
capacity of bearing rated short-time withstanding current
(peak).
b) Embedded poles
structure
Small-sized vacuum
arc-extinguisher and other parts of main circuit are directly
embedded in epoxy resin through advanced AGP technology. Not only
the poles assembly process is simplified, but also the reliability
of the vacuum arc-extinguisher loop is improved., and the surface
of vacuum arc-extinguisher is free from the effects of external
mechanical force and ambient.
Circuit-breakers
mechanism has excellent corrosion prevention performance and
advanced design
Structural member
adopts super strong corrosion resistance and salt mist Zn-Co alloy
surface treatment; driving member adopts high hardness, high wear
resistance, corrosion resistant Ni-P alloy surface treatment. Drive
bearing adopts international brand INA oil-free graphite bearing
with high strength and good abrasive resistance.
The VSV series are
circuit-breaker Class C2
During cut-off of
capacitive current, circuit breaker has extremely low heavy
breakdown probability, meeting the requirement of circuit-breakers
Class C2.
The VSV series are
circuit-breakers Class E2
The circuit-breakers
passed all tests in Testing Center of Senyang High Voltage Appartus
Research Institute and Testing Center of Xi\'an High Voltage
Appartus Research Institute, meeting the requirement of Class E2,
cut-off full-capacity short circuit current of small current
circuit breaker reaches *0 times, and cut-off full-capacity short
circuit current of big current circuit breaker reaches *0
times.
The VSV series are
circuit-breaker Class M2
Mature integrated
operating mechanism has stable and reliable performance, and long
service life,which can be used in places with frequent operation.
The circuit breaker can meet the requirement of Standard Grade M2,
mechanical service life is as high as *0,**0 times.
Adopt buffers with
excellent buffer performance
Specially designed
buffer can reduce overshoot of brake separating and rebound of
brake reversing of circuit breaker, thus enhancing the mechanical
life of circuit-breakers.
Adopt insulating
tension pole made of nylon material
Insulating tension
pole adopts nylon *6 plus glass fiber material, ensuring intensity
and toughness, as well as electrical performance.
