I. Product Overview:
With the development of science and technology, the requirements for the safety and reliability of electricity use are increasingly higher. High voltage circuit breakers bear the dual tasks of control and protection in power systems, and their performance is directly related to the safe operation of the power system. Mechanical characteristic parameters are one of the important parameters for judging the performance of circuit breakers.
The KEKGY-C (6-port) High Voltage Switch Mechanical Characteristic Tester is designed based on the latest standard GB1984-2003 "High Voltage Alternating Current Circuit Breakers" and refers to the power industry standard DL/T846.3-2004 "General Technical Conditions for High Voltage Test Equipment - Part 3: High Voltage Switch Comprehensive Tester" as the design basis. It provides convenience for dynamic analysis of various types of circuit breakers and can accurately measure the mechanical dynamic characteristic parameters of high voltage circuit breakers such as low oil, multi-oil, vacuum, and SF6 at various voltage levels.

(6) Bounce Time                   (16) Current Waveform Curve (Dynamic)

(7) Bounce Count                   (17) Time-Displacement Curve (Dynamic)

(8) Displacement                          (18) Speed-Displacement Curve (Dynamic)

(9) Over-Travel                          (19) Adjustable Power Supply (DC 20V～270V)

(10) Bounce Amplitude                       

Note: The adjustable power supply is dedicated for switch operating voltage percentage tests. The computer communication interface is for on-site analysis, requiring synchronous use of the computer and the instrument. Time units are in ms, speed in m/s, and distance in mm.

2.2 Features

(1) Designed and developed based on the latest domestic standard GB/T1984-2003 "High Voltage Alternating Current Circuit Breakers" and referencing the power industry standard DL/T846.3-2004 "High Voltage Switch Comprehensive Tester";

(2) Suitable for mechanical dynamic characteristic testing of various high voltage circuit breakers up to 500KV voltage level;

(3) Capable of measuring actual displacement and custom displacement;

(4) Can perform single close, open, close-open, and close-open-close operations;

(5) Easy wiring and simple operation; a single close (open) action provides all close (open) data, automatically saves data for later query, and allows on-site printing of all data and motion curves;

(6) Operates via human-machine dialogue with Chinese prompts;

(7) Accurate data, strong anti-interference, compact size, lightweight, and aesthetically pleasing;

(8) Equipped with an internal clock circuit displaying current year, month, day, hour, minute, and second; automatically saves settings and test data even after power loss;

(9) Features internal delay protection, automatically cutting off coil voltage after circuit breaker action, effectively protecting the circuit breaker device and high voltage switch tester;

(10) Automatically identifies operation type (closing or opening) and provides Chinese prompts;

(11) Switch action control includes internal control (tester issues close/open commands), external control (external control energizes the coil), and manual close/open; manual operations do not generate coil energization signals;

(12) Dynamically analyzes the relationship between time, displacement, and speed at each motion point of the circuit breaker;

(13) Can be configured with a laptop and instrument upload software for online review and office printing.
