Cúrsaí Teicneolaíocha
Tá an t-úsáid teicneolaíochta seo gaol le réimse an chuid mhéide ring, go háirithe cistin ghuthaíoch shuntasach ar bhonn aer.
Teicneolaíocht Comhaimseartha
Is úirlis deilgtheach í an cistin ghrinn a dúnann roghnacha deilgtheacha ar bhonn ard-voltach i gcaisín meite nó a chumhachtóidh i gcaisín grinn. Tá an córas bunaithe ar nascadh busbars na mbuiséad éagsúla, agus is é a lár a dhéanann saincheisteanna deilgtheacha agus fiosrúcháin. Tá struchtúr simplí, méid bheag, costas íseal, paraiméad cumhachta maith, agus slándacht ard aici.
Úsáideann cistí ghrinne airshluaite (má tá siad ina cistí ghrinne airshluaite) aer scartha mar mheadhan sluaite agus smál-díchúiseoireachta. Is fearr a gcumas ná SF6 gas gan polaíocht comhshaoil a chur ar siúl. Tá na scuabanna beatha ard-voltacha suite i gcaomhnú aer faoi bhaintle constand nach bhfuil tionchar atmaisféarach air, agus is oiriúnach iad do réimsí speisialta cosúil le páirceanna, réimsí sal-alkali, agus áiteanna madraí.
Sa theicneolaíocht reatha, úsáideann cistí ghrinne airshluaite formlacha comhbhunaithe cosúil le scuab deilgtheach-scuirteoir, scuab deilgtheach-fuse ard-voltach, agus scuab guthaíoch-scuirteoir. Is féidir le caibidí a úsáid go neamhspleách nó a chumhachtú go saoránach. Ach tá na lochtanna seo leanas ann:
Nuair a chumhachtófar, taispeánfar stádas oibriúcháin amháin trí chuomhachtóireacht relay agus cuibhreann an uirlis, ag iarraidh seiceálacha rialta láithreach agus déantúsaireachta, rud a chuirfí costas ardh ar.
Tá sé deacair an t-ealaíontacht a réiteach go héifeachtach sa chaibid: Tá brón ar an ealaíontacht a chur amach go héifeachtach trí chomhluadar aer inmheánach, agus is féidir struchtúr simleach oscailte aer a chur isteach ar mhórán uisce, ag cur isteach ar slándacht deilgtheach. Tá feabhas aige go ginearálta.

Leagan Forbraíte: Tá an relay and instrument compartment, control compartment, and air chamber distributed on the same side, combined and connected with the switch compartment and busbar compartment, effectively expanding busbar functions, avoiding wiring confusion, and providing high space utilization.
Úsáid Intileachta:
The data storage module sends circuit status and environmental data collected by the relays, temperature sensors (first and second), and humidity sensor in real-time via the wireless transmission module, facilitating integrated monitoring of connected cabinets, improving intelligent management, and reducing maintenance costs.
After the wireless reception module receives a control signal, the PLC controller activates as needed: the fan set for internal circulation heat dissipation, or the second fan to draw in external air through the moisture absorption plate for external circulation cooling. When the temperature is low, only the first fan can be activated, using hot air from the switch compartment to dehumidify the moisture absorption plate. This enhances energy efficiency, avoids moisture introduction, and balances electrical safety with energy savings.

The cabinet interior includes the busbar compartment, relay and instrument compartment, switch compartment, cable compartment, control compartment, and air chamber. Each area is separated by partition plates, with clear functions and no interference.
The busbar compartment is located in the upper part, with the relay and instrument compartment on one side and the switch compartment at the bottom. One side of the switch compartment sequentially has the control compartment and the air chamber, while the other side is the cable compartment.
Core Components of Each Area
Busbar Compartment: Contains busbars, the first temperature sensor, and the fan set electrically connected to the PLC controller.
Relay and Instrument Compartment: Houses relays for collecting equipment operating status (e.g., current, voltage, power).
Switch Compartment: Equipped with the load switch set, the second temperature sensor, and the humidity sensor. The load switch set is connected to the busbar compartment via the insulator set (with three interval insulators) and is connected to fuses, the operating mechanism, and the current transformer. A frame is provided between the current transformer and the cabinet body.

The data storage module is connected to the relays, the first temperature sensor, the second temperature sensor, and the humidity sensor. The wireless reception module is connected to the PLC controller.

The first partition plate has a return air outlet and a supply air outlet, equipped with the first fan and second fan respectively (both electrically connected to the PLC controller). The first fan is connected to the moisture absorption plate, located between the second fan and the air inlet mesh.
Cable Compartment: Houses the interconnected earthing switch, lightning arrester, and cable.
Cabinet Body and Profile Structure
The cabinet body is formed by riveting several frame plates. Both the frame plates and the frame use the profile body.
The four corners of the profile body have plug-in blocks. The outer wall of the plug-in block is inclined relative to the profile body, with a first through hole inside and limit plates on both sides. The center has a second through hole; its top and bottom cross-section is an isosceles trapezoid, and both sides are concave arcs. Both sides of the profile body also have concave arc plates with several waist-shaped mounting holes.
II. Modh Oibre agus Forbhaisí
Modh Cumhachta
The profile bodies achieve quick connection via the plug-in blocks with limit plates, and are then riveted and fixed using corner connecting pieces through the waist-shaped mounting holes on the concave arc plates. The assembly process is convenient and stable, also providing shock resistance, lower cost and weight, and ease of transportation.
Modh Oibre agus Proiseas Úsáid Intileachta
The busbar compartment connects multiple ring main units. The load switch set connects to the busbar compartment via the insulator set. The fuse disconnects the circuit by melting its element when current exceeds the limit. The operating mechanism performs closing and opening operations. The current transformer proportionally converts a large primary current to a small secondary current, protecting the measurement circuit, and transmits signals to the earthing switch, lightning arrester, and cable in the cable compartment.
The relays collect equipment operating status and transmit it to the data storage module on the circuit board. This module also stores temperature signals from the first and second temperature sensors and the humidity signal from the humidity sensor. These are then sent in real-time via the wireless transmission module to a base station or control terminal for remote monitoring.
The control terminal can send commands to the PLC controller via the wireless reception module, or the PLC controller can make automatic judgments: When heat dissipation is needed, it activates the fan set for internal circulation heat dissipation, or starts the second fan to draw air through the inlet mesh, dehumidify it via the moisture absorption plate, and supply it into the cabinet for external circulation heat dissipation. When the temperature does not meet the condition for starting the second fan, only the first fan can be activated to dehumidify the moisture absorption plate, reducing energy consumption while avoiding moisture introduction.
Forbhaisí Bunúsacha
Real-time monitoring and intelligent control of the cabinet's temperature, humidity, and equipment operating status are achieved. This ensures electrical safety while reducing energy consumption by activating equipment on demand, balancing practicality and energy efficiency.
