Customized drawer assembly production line

Drawout switchgear cabinets, such as low-voltage drawout cabinets MNS, GCK, or medium-voltage KYN series, are core components of power distribution systems. Their production lines must balance precise assembly with modular flexibility. Below is a detailed analysis of the production lines for various types of drawout switchgear cabinets, covering the manufacturing processes of low-voltage, medium-voltage, and intelligent drawout units.

Discription

Low-voltage drawer-type cabinet production line (such as MNS/GCS series)

Drawer unit modular assembly: robots automatically install tracks, one-time insertion (tolerance ±0.5mm). Interlock mechanism test: simulate mechanical locking (prevent pulling out under load), force sensor calibration for operating force (≤50N). Loop resistance detection: 100A constant current source measures contact resistance (≤100μΩ).

Medium voltage drawer-type cabinet production line (such as KYN28-12 series)

Handcart circuit breaker assembly: Visual guidance for robotic arm installation of star-shaped contacts (pressure control 200±10N). Valve mechanism adjustment: Laser displacement sensor verifies valve synchronization (opening and closing time difference < 0.1s). Partial discharge shielding treatment: Automatic application of conductive grease (thickness 0.2~0.3mm) to suppress partial discharge.

Intelligent drawer unit production line

Smart module integration: automatic assembly of wireless temperature sensors (accuracy ±1℃) and power quality monitoring modules. Communication testing: analog signal injection (4~20mA) to verify Modbus/61850 protocol communication.
