Mekanismo sa Pana ng CT40

Ang CT40 spring operated mechanism usa ka power drive component nga gidesign pinaagi sa espektibo para sa 10kV-40.5kV medium ug high voltage switchgear ( sama sa vacuum circuit breakers, SF6 load switches). Pinaagi sa spring energy storage isip core power source, naging usa na key equipment kini sa medium voltage distribution systems, industrial substations, ug outdoor distribution networks tungod sa iyang stable mechanical performance, flexible operation mode, ug wide adaptability. Ito naghatag og precise ug reliable power support alang sa switch opening ug closing operations, suportando ang safe ug stable operation sa power system.
1、 Core working principle: Efficient logic driven by spring energy storage
Ang core sa CT40 spring operated mechanism mao ang mechanical transmission cycle sa "energy storage release", nga nagdrive sa switching device aron makumpleto ang opening ug closing actions pinaagi sa elastic potential energy nga gitubo sa spring. Ang specific process mao kini:
1. Energy storage stage
Electric energy storage: Sa default, ang electric mode mao ang preferred. Ang motor (AC220V/DC220V, power ≤ 150W) nagdrive sa reduction gear set aron mogamit ug nagdrive sa energy storage shaft aron mogira. Ang energy storage shaft niminom sa closing spring pinaagi sa cam mechanism. Kung ang spring niminom ngadto sa rated stroke (corresponding to the energy storage completion position), ang energy storage pawl engages ug locks sa ratchet wheel. Sa parehas nga oras, ang stroke switch triggers ang motor aron magcut off power, ug ang energy storage process mohuman (time ≤ 15s), ug ang mechanism moadto sa waiting closing state.
Manual energy storage: Isip emergency backup method, kung ang motor mao'y fail o walay power supply, ang energy storage shaft mahimo molig-on pinaagi sa paginsert sa manual rocker arm, manually compressing ang closing spring hangtud ang pawl ma-lock. Ang rocker arm kinahanglan molig-on ≤ 40 turns (with a speed of 30r/min) sa tanang proseso aron sigurado ang normal energy storage sa emergency situations.
2. Execution of opening ug closing actions
Closing operation: Pagkahuman sa pagtanggap sa closing signal, ang closing electromagnetic iron energized aron itolok sa release mechanism aron irelease ang energy storage pawl. Ang closing spring instantly releases elastic potential energy, nga nagdrive sa moving contact sa switchgear aron quick close pinaagi sa connecting rod transmission mechanism, kompletando ang closing process; Sa parehas nga oras, ang closing action mao'y synchronously stretch ang opening spring, storing energy in advance for subsequent opening operations.
Opening operation: Pagkahuman sa pagtanggap sa opening signal (o manually pulling the opening handle), ang opening electromagnet (o mechanical release component) activated, ang opening lock released, ang opening spring releases energy, ug ang transmission mechanism pulled aron quick disconnect ang moving contact, cutting off the circuit (opening time ≤ 25ms, can quickly cut off the fault current, reduce the impact of accidents).

Key structural design: reliable characteristics adapted to medium voltage scenarios
1. High stability mechanical architecture
Modular component design: Ang energy storage component (spring, gear set), transmission component (connecting rod, cam), ug control component (electromagnet, travel switch) separated into independent modules, connected by precision shaft sleeves with a matching accuracy of 0.05mm, reducing mechanical friction loss ug extending mechanical life (≥ 10000 opening ug closing operations).
High strength material selection: Ang closing spring gihimo sa 60Si2MnA alloy spring steel, nga gisulod sa isothermal quenching ug tempering heat treatment, with a tensile strength of ≥ 1800MPa ug no permanent deformation after long-term energy storage; Ang transmission connecting rod ug energy storage shaft gihimo sa Q235B cold-rolled steel plate, with a galvanized surface (zinc layer thickness ≥ 8 μ m) ug a salt spray corrosion resistance of 480 hours, suitable for humid ug dusty distribution environments.
2. Convenient operation ug status monitoring
Visual status indication: Ang mechanism housing equipped with mechanical pointers for "energy storage status" (red - not stored/green - stored) ug "opening/closing status" (blue - open/yellow - closed), nga intuitively determine ang current status sa equipment without disassembly, facilitating on-site inspection ug troubleshooting.
Compatible installation interface: Ang bottom designed with standardized installation holes (hole spacing suitable for universal installation dimensions of 10kV-35kV circuit breakers), nga do not require customized brackets ug can be fixed with 4 M12 bolts, reducing installation time to less than 30 minutes; The electrical wiring adopts plug-in terminals, ug ang connection sa opening ug closing electromagnet ug travel switch does not require welding, improving the efficiency of on-site debugging.
