RCLK-12 Circuit Breaker High Voltage Switch Characteristic Tester
The "RCLK-12" you mentioned typically refers to a 12-break high voltage switch mechanical characteristic tester (common industry models include RTKC-F, etc.). This is a professional portable instrument used to detect the mechanical dynamic characteristic parameters of high voltage circuit breakers. It is mainly used to evaluate the performance of circuit breakers during opening and closing operations in power systems, ensuring the safe and stable operation of the power grid.
The following is an analysis of the core technical features, functions, and parameters of this testing instrument:
I. Core Functions and Application Scope
Wide applicability of equipment: Suitable for mechanical characteristic tests of SF6 switches, GIS combined appliances, vacuum switches, low-oil/multi-oil switches, and contactors of various voltage levels (up to 500kV) produced domestically and internationally.
Comprehensive parameter measurement: A single operation can simultaneously obtain the inherent opening/closing times, same-phase/phase-to-phase synchronization, closing bounce time and count, just-open/just-close speed, maximum speed, travel (open distance, overtravel, over-travel, etc.), and opening/closing coil current waveforms for 12 breaks.
Reclosing and low voltage testing: Supports time testing for reclosing processes such as close-open, open-close, and open-close-open; built-in adjustable DC power supply can automatically complete low voltage action tests of circuit breakers.
II. Core Technical Features
Strong anti-interference capability: Uses advanced photoelectric isolation technology, allowing easy and accurate testing and measurement even in strong electric field environments with live bypass busbars in 500kV substations.
Intelligent operation and display: Equipped with a large screen, wide temperature background light LCD, full Chinese menu prompts, and human-machine dialogue operation. Supports simultaneous display of time, travel, speed, and waveforms on the same screen.
Flexible sensor configuration: Can be equipped with linear sensors, rotary sensors, or acceleration sensors, easy to install, and supports custom travel and speed calculation methods.
Data storage and export: The host can store hundreds of sets of on-site test data, with a built-in real-time clock. Equipped with a micro printer, RS-232 interface, and USB interface, convenient for on-site printing or PC connection for data analysis and report generation.
III. Main Technical Parameters
Time measurement: Range up to 25000.0ms, minimum resolution 0.01ms; high precision gear error is only 0.1ms ± 1 digit.
Speed measurement: Range 20.00m/s, resolution 0.01m/s; error within 0-2m/s is ±0.1m/s, above 2m/s error is ±0.2m/s.
Travel measurement: Automatically adapts according to circuit breaker type (e.g., vacuum circuit breaker 50mm, SF6 circuit breaker 300mm, low-oil circuit breaker 600mm), resolution up to 0.1mm.
Built-in power supply: Provides DC 0～280V digitally adjustable operating power (instantaneous maximum current up to 20A), no need for external secondary power supply.
Operating environment: Working temperature -10℃～40℃, relative humidity ≤80%RH, input power AC 220V±10%.
IV. On-site Operation Precautions
Reliable grounding: The instrument housing must be reliably grounded to prevent induced voltage from damaging equipment or endangering personal safety.
Power supply check: Confirm the input power is AC 220V, strictly prohibit mistakenly connecting to 380V power supply.
Sensor installation: Linear sensors need to be firmly attached to the moving contact conductive rod; rotary sensors need to be installed on the main shaft or crank arm, ensuring smooth transmission without jamming.
Safety protection: The instrument has a delay protection function, which automatically cuts off the action power after the circuit breaker operates, to protect the equipment and the instrument.
