12kv High Voltage Vacuum Contactor
VCE VACUUM CONTACTOR AND VFC VACUUM CONTACTOR - FUSE COMBINATIONS
Product handling and installation should be handled with great
care, so as not to damage the epoxy resin casting parts.
When Product lifting from the packing ,The wire should be hung in
obvious signs of lifting hole, Moving can not make the
upper and lower arm force, At the same time, we should not let the
product surface suffered serious impact .
Products have been strictly inspected before they go out,
Parameters and functions conform to technical requirements
and rules. For the purpose of reliable, a first circuit must be
carried out the following operations before charaging.
1 The installation box list be checked whether random file is
complete ,and check whether the product nameplate and
certificate are consistent with purchase order .
2 Checking the product whether it have damaged, or other direct
3 Cleaning the products of insulation surface, transport pollution
may affect the product in the process of insulation
4 Using the method of secondary electrifying to test the opening
and closing operation of the switch, Observing
whether the state of the switch position indicator is normal .
5. VFC handcart should be pushed by service handcart rack, and wave
in the test, the product in the opening condition
should be able to smooth move between the working position and test
Products should be tested before formal operation of power
frequency withstand voltage test, we consider the power
frequency withstand voltage test for many times under the influence
of the unrecoverable isulating performance, and do not
recommend according to the full capacity to test, 10 kV products
shall be carried out in accordance with the 38 kV 1 min, 7.2
kV products shall be carried out in accordance with the 28 kV/ 1
The installation of VFC basic operation can refer to the
middle-placed handcart installation of circuit breaker .
