Vacuum circuit breaker is the most commonly used type of
high-voltage circuit breaker, mainly divided into two kinds of
indoor and outdoor. We mainly focus on indoor vacuum circuit
breakers. (Indoor circuit breakers: High-voltage circuit breakers
that do not have the performance of protection against wind, rain,
snow, ice and dense frost, etc. and are suitable for installation
and use inside buildings.)The vacuum circuit breaker is named after
its interrupting medium and the insulating medium of the contact
gap after interrupting is high vacuum; it has the advantages of
small size, light weight, suitable for frequent operation and
interrupting without maintenance, and is more popularly used in the
3kV-40.5kV distribution network. The components of vacuum
circuit breaker are vacuum interrupter, electromagnetic or
spring-operated mechanism, bracket and other parts.Vacuum
interrupter is the core component of vacuum circuit breaker, its
main role is, through the excellent insulation of the vacuum inside
the tube to make the medium and high voltage circuit cut off the
power can quickly extinguish the arc and suppress the current to
avoid accidents and accidents.There are two kinds of operating
mechanism: spring-operated mechanism and permanent magnetic
operating mechanism.The conductive circuit is divided into
insulated cylinder form (vacuum interrupter is installed in the
insulated cylinder) and sealed pole form (vacuum interrupter is
installed in the epoxy resin).The VSG mechanism uses a cam (in the
core module of the mechanism) to drive the spindle directly (in the
frame spindle module) to reduce the transmission link and improve
the transmission efficiency (no hinge connection). Reduce the
energy input of the product and increase the service life of the
product. Install the main circuit module, that is, complete the
basic configuration of the vacuum circuit breaker. Then install the
chassis car module, the contact arm, the contact, and the
insulating sleeve to complete the configuration of the hand-cranked
circuit breaker. Ambient condition1. The ambient air
temperature does not exceed 40ºC, and the average value measured
within 24h does not exceed 35ºC.2. The minimum ambient air
temperature is -5ºC for the "-5 indoor" level, -15ºC for the "-15
indoor" level and -25ºC for the "-25 indoor" level. 15ºC, and -25ºC
for the "-25 house" level.3. The effect of sunlight radiation can
be ignored.4. The altitude does not exceed 1000m.5. The surrounding
air is not significantly contaminated by dust, smoke, corrosive
and/or flammable gases, vapors or salt spray. Technical
features 1.The first generation of the builtin type handcart
in China with independent intellectual rights .It features a
matured technology and high price/performance ratio .2.The key
parts adopt nickel-phosphorous alloy plating with perfect wear
resistance and corrosion resistance .3.The key parts are made by
ourselves to ensure the products to meet the designing
requirement of design4.The cylindrical composite insulation main
circuit features small volume,free of maintenance and few
service.DrawingFAQ:Q: Could I have prices of your products?A: Welcome. Please feel free to send us inquiry here. We will reply you within 24 hours.Q: Can I get a sample before the bulk order?A: Yes, we welcome sample order to test and check quality.
