CHN3-12Q/280 4000A 10kV Epoxy Resin Insulators Contactor Box Spolt
Bushings
Gas, Steam, dust without seriously affecting the insulation of the
contact box
No exploration or corrosive submission.
Technical Data & Requirements Requirement Technical data and
requirements 1. Contact box and contact should be able to withstand
frequency test voltage(effectiveness) 42 KV, 5 minutes, lightning
shock(peak) 75 KV;
The label contact to earth call with power freedom test volume of
42 KV for 5 minutes and
Lightning impact vplage(peace value) of 75KV;
The temperature rise of the end of the contact box at the end of
the line under long-term operation does not exceed 65 ℃ under the
rated electricity;
The experience of lead-out final call not more than 65 °C if the
contact box is used for long time in rate current con the
wall-piercing sleeve is used to increase the insulation function of
the mother-row in the cabinet and play a certain supporting role.
In the middle, in the end.
Insulators only act as support, sometimes using a belt point sensor
directly instead of an insulator as well as as as sensors.
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.
