36kV Isolated handcart Fit with High Voltage Indoor switch Cabinet
Description
1. ZN85-40.5 Indoor High Voltage Vacuum Circuit Breaker is
three-phase voltage 50Hz Power , 12kV Rate voltage power system
indoor switch equipment . As grid Equipment and Electrical
Equipment in Industrial and Mining Enterprises . Lend Itself to
frequent Opration on Rate Voltage and Opening short Circuit Current
.
2. The circuit breaker adopts an integrated design of operating
mechanism and circuit breaker body , It can be used as a fixed
installation unit or with a professional propulsion mechanism ,Role
of component vehicle unit .
3. Altitude is after 2000M .
4. Temperature is from +40 degree to -30 degree
The cabinet is large but easier to maintain. Medium case is large,
but maintenance is more convenient. Ring case is small, but
maintenance is not convenient.(Schneider SM6 now has a high voltage
loop switch cabinet with special SFset circuit breaker. SGN1A-12(Z)
small fixed separator, developed jointly, can achieve the basic
function of medium case using ABB LEG(Z1)-12 circuit breaker, but
the ring net case or small fixed compartment can be set up as a low
voltage circuit breaker. Only according to the fixed mode of
installation, so that when the circuit breaker failure, need to be
replaced immediately, not only need to cut off the upper power
supply, but also trouble to replace. It is convenient to replace
the handcar switch. So the current ring net cabinet is generally
made maintenance free, but the cost is higher. For opening and
closing stations, power substations, such as large power, the more
important load to use the cabinet to protect. At present, Wuhan
city according to the current power supply department requirements,
generally choose ring cabinet, the installation capacity of the
Transformer with its general requirements to control within 1250
KVA.
