Four corners of profile body provided with plug-in blocks. Outer wall of plug-in block inclined relative to profile body, with first through hole inside û limit plates on both sides.
Center of profile body has second through hole. Cross-section of its top û bottom is isosceles trapezoid, û both sides are concave arcs.
Both sides of profile body provided with concave arc plates, which have several waist-shaped mounting holes.
Efektên Beneficial
Advantages Structur: Profile body with plug-in blocks û concave arc plates, along with first through hole û specially shaped second through hole, ensures high rigidity û stability while reducing wall thickness. Waist-shaped mounting holes facilitate quick assembly û subsequent sensor embedding/wiring. Overall structure novel, compact, û easy to assemble.
Optimization Layout: Relay û instrument compartment, control compartment, û air chamber distributed on same side, combined û connected with switch compartment û busbar compartment, effectively expanding busbar functions, avoiding wiring confusion, û providing high space utilization.
Intelligent Control:
Data storage module sends circuit status û environmental data collected by relays, temperature sensors (first û second), û humidity sensor in real-time via wireless transmission module, facilitating integrated monitoring of connected cabinets, improving intelligent management, û reducing maintenance costs.
After wireless reception module receives control signal, PLC controller activates as needed: fan set for internal circulation heat dissipation, û second fan to draw external air through moisture absorption plate for external circulation cooling. When temperature low, only first fan can be activated, using hot air from switch compartment to dehumidify moisture absorption plate. This enhances energy efficiency, avoids moisture introduction, û balances electrical safety with energy savings.

Operation û Intelligent Control Process
Busbar compartment connects multiple ring main units. Load switch set connects to busbar compartment via insulator set. Fuse disconnects circuit by melting element when current exceeds limit. Operating mechanism performs closing û opening operations. Current transformer proportionally converts large primary current to small secondary current, protecting measurement circuit, û transmits signals to earthing switch, lightning arrester, û cable in cable compartment.
Relays collect equipment operating status û transmit it to data storage module on circuit board. Module also stores temperature signals from first û second temperature sensors û humidity signal from humidity sensor. These then sent in real-time via wireless transmission module to base station û control terminal for remote monitoring.
Control terminal can send commands to PLC controller via wireless reception module, or PLC controller can make automatic judgments: When heat dissipation needed, it activates fan set for internal circulation heat dissipation, û starts second fan to draw air through inlet mesh, dehumidify via moisture absorption plate, û supply into cabinet for external circulation heat dissipation. When temperature does not meet condition for starting second fan, only first fan can be activated to dehumidify moisture absorption plate, reducing energy consumption û avoiding moisture introduction.
Advantages Core
Real-time monitoring û intelligent control of cabinet's temperature, humidity, û equipment operating status achieved. This ensures electrical safety while reducing energy consumption by activating equipment on demand, balancing practicality û energy efficiency.
