Example for 1 module
● Spring operating mechanism with dual maloperation-proof system
Operating mechanism includes load switch operating mechanism, switch-fuse combination operating mechanism, and circuit breaker operating mechanism. It
can carry out by manual or motor after fixing electromotor. The operating mechanism itself has dual maloperation-proof function: firstly, as the
interlocking device is equipped inside the mechanism, so the operator must operate according to the regulated procedure, otherwise the operation can’t
carry out, unless the operator damages the interlocking device by force. Secondly, there is a movable baffle before the position of operating hole,
which can avoid the faulty operation by lock protection.
● Mechanical interlocking for circuit breaker / load switch
Both circuit breaker and load switch is vacuum switch. The reliable mechanical interlocking not only exists between vacuum switch and disconnector/
earthing switch, but also exists between earthing switch and the front panel of cable compartment, which prevents the faulty operation and avoids safety
● Simply and convenient connection for switch and cable
The cable compartment equips with European standard bushing which meets the standard of DIN47636. Its cable terminal is made of silicon rubber which can
touch and with function for flood proofing, what is more, it can also equip with surge arrester device.
● Rustproof cabinet with high mechanical strength
Cabinet is made of 3mm steel plate and the steel plate is made by electrostatic spraying technology, which makes the cabinet with strong mechanical
strength and good rust protection.
● Green & environment friendly solution
CKSS solid-insulated switchgear is a completely environment-friendly product.
---- Stable chemical performance of epoxy resin makes CKSS without any poison or harm.
---- It will not produce any volatile matter in the production process of automatic pressure gel (APG technology). No spill impurity produced after
gelling. No waste gas produced after solidifying.
---- The switchgear has no SF6 gas inside. No waste or harmful materials produced during working.
---- After the service life, the epoxy resin can be decomposed soon by heat treatment and chemical treatment. It can recycle either by extraction
---- All CKSS materials can be recycled. It will not produce any waste liquid or waste gas.
● Safe and reliable
CKSS solid-insulated switchgear has excellent safety performance.
---- Completely without SF6 gas makes the switchgear to avoid the explosion accident causing by SF6 gas.
---- Its vacuum interrupter has explosion proof function, and solid-insulated layer has further protection to ensure the safety.
---- The independent module design between each phase makes the switchgear to avoid short-circuit accident causing by phase-to-phase fault.
---- The interlocking system between main switch, disconnector, earthing switch and cable compartment door ensure the personal safety under repairing
---- The watch window provides visual indication for the opening/closing position of the disconnector, which strengthens the safety of operating and
---- The glass transition temperature of epoxy resin ensures the insulating capacity of epoxy resin and silicon rubber keep unchanging in the high
---- The operating mechanism adopts all-gear driving system, which enhances the reliability of mechanism.
---- The protection class of solid-insulated switch body reaches IP67.
---- It can work as well as normal condition even if soaking in the water of 1m height within 48hours.
● Single handle operation for disconnector/ earthing switch
The switchgear has closing position and earthing position. It just needs one operating handle to control. The mechanical interlocking exists between
main switch and disconnector/ earthing switch, which makes the disconnector/earthing switch can’t operate until the main switch is on the position of opening. It also have the reliable interlocks between the main switch and the front panel of cable compartment.
