Cabinet Body and Profile Structure
Cabinet body tana form by riveting several frame plates. Both frame plates da frame tana use profile body.
Four corners of profile body tana da plug-in blocks. Outer wall of plug-in block tana da inclination relative to profile body, tana da first through hole inside and limit plates on both sides. Center tana da second through hole; top and bottom cross-section tana da isosceles trapezoid, da kuma both sides tana da concave arcs. Both sides of profile body tana da concave arc plates tana da several waist-shaped mounting holes.
II. Working Principle and Advantages
Assembly Method
Profile bodies tana achieve quick connection via plug-in blocks with limit plates, and tana then riveted and fixed using corner connecting pieces through waist-shaped mounting holes on concave arc plates. Assembly process tana convenient da stable, also providing shock resistance, lower cost and weight, da kuma ease of transportation.
Operation and Intelligent Control Process
Busbar compartment tana connect multiple ring main units. Load switch set tana kasa busbar compartment via insulator set. Fuse tana disconnect circuit by melting its element when current exceeds limit. Operating mechanism tana perform closing and opening operations. Current transformer tana proportionally convert large primary current to small secondary current, protecting measurement circuit, and transmitting signals to earthing switch, lightning arrester, da kuma cable in cable compartment.
Relays tana collect equipment operating status and transmit it to data storage module on circuit board. This module tana also store temperature signals from first and second temperature sensors and humidity signal from humidity sensor. These tana then sent in real-time via wireless transmission module to base station or control terminal for remote monitoring.
Control terminal tana can send commands to PLC controller via wireless reception module, or PLC controller tana make automatic judgments: When heat dissipation tana needed, tana activate fan set for internal circulation heat dissipation, or start second fan to draw air through inlet mesh, dehumidify it via moisture absorption plate, and supply it into cabinet for external circulation heat dissipation. When temperature does not meet condition for starting second fan, only first fan tana be activated to dehumidify moisture absorption plate, reducing energy consumption while avoiding moisture introduction.
Core Advantages
Real-time monitoring and intelligent control of cabinet's temperature, humidity, and equipment operating status tana achieved. This ensures electrical safety while reducing energy consumption by activating equipment on demand, balancing practicality and energy efficiency.
