Product Features:
·The switchgear cabinet body adopts aluminum-zinc coated steel sheet with multiple folding and riveting assembly processes.
·The switchgear is divided by metal plates into four independent functional compartments, each with its own independent pressure relief channel.
·The switchgear adopts a luxury explosion-proof door: the middle door uses a toothed locking device. The door opening and closing adopts a lever structure with door lock rotation and lifting to increase operational safety; the double-folded high-strength door locking structure ensures that after the middle door is locked, it engages with the three sides of the switchgear cabinet body, effectively preventing the internal arc from pushing open the middle door and injuring people.
·The switchgear cabinet has high sealing degree to prevent debris and insects from invading the equipment, with protection degree IP4X.
·Simple and effective interlocking to prevent misoperation.
·Equipped with a new generation of high-performance and highly reliable VEG solid-sealed vacuum circuit breaker. The number of parts is only 1/3 of similar domestic products; all friction parts use long-life grease or oil-free bearings. Its unique friction tripping method has strong seismic resistance. The advanced APG process directly solid-seals the vacuum arc-extinguishing chamber and primary conductive circuit in special epoxy resin to form a main conductive circuit module, which not only improves the insulation and anti-pollution ability of the arc-extinguishing chamber but also reduces the resistance of the pole circuit.
·Replacing the circuit breaker is very simple, with good handcart interchangeability.
·High-precision current and voltage transformers are used. Through reasonable electric field design, excellent shielding materials, and insulation processes, the product can meet the user's requirement of no partial discharge (<2PC).
·Explosion-proof arresters with built-in thermal fuse explosion-proof tripping devices are adopted, safe and reliable.
·Equipped with microcomputer-type multi-function relay integrated protection devices.
·The position of the handcart and earthing switch can be observed through the panel door when the cabinet is closed.
·The cable chamber has ample space and can connect multiple cables. The cable installation height is greater than 700mm.
·The product complies with standards such as GB/T3906, DL/T404, and IEC62271-200.
