Model and meaning
Structural description
Completely metal armored, modular structure, wide range of combination options.
The cabinet body is made of imported aluminum-zinc coated steel plate and processed by CNC machine tools. It adopts multiple folding processes and is connected with rivet nuts and high-strength bolts. It has high precision, strong corrosion resistance, light weight, high strength and strong parts versatility.
It can be assembled with ZN63A-12 (VS1), VD4 series, EV12 series, VEP series and other vacuum circuit breakers. It has wide applicability, high reliability, and is maintenance-free all year round . The test position has positioning and display devices at each position, which is safe and reliable. Various types of handcarts change according to modular building blocks, ensuring that cars of the same specifications can be freely interchanged and transported by special carrier vehicles, making operation light and flexible.
The cable room can accommodate up to 9 single-core cables.
The highly reliable interlocking device fully meets the five-proof requirements.
Each high-pressure chamber has a pressure relief channel to ensure personal safety.
The cabinet door is equipped with an observation window to observe the working status of indoor components.
The cabinet body can be made into cabinets of equal or unequal height according to user requirements.
It can be equipped with an advanced and reliable microcomputer detection, control and protection system.
