ET-8006 Graphite Contact Switch Analyzer

product overview

The ET-8006 graphite contact switch analyzer has an industrial computer as its main unit. The Siemens graphite contact switch test can test the dynamic resistance waveform of six fracture surfaces of the graphite contact switch. The inherent opening and closing time of 12 fracture surfaces, in phase and phase to phase synchronization. Bounce time, bounce frequency, bounce process, bounce waveform. Speed just divided, just closed speed, maximum speed, speed waveform. Overtravel and overshoot of travel. The opening and closing current values and waveform diagrams of the current opening and closing coils. Arbitrarily set the reclosing interval time value, metal short-circuit time, and no current interval time for reclosing.
The action voltage machine provides a DC20-250V, 10A (rated working) digital adjustable circuit breaker action power supply, allowing for arbitrary setting of the action voltage values of the opening and closing coils, and can also perform low voltage action tests on circuit breakers. The installation of the universal speed sensor is extremely convenient and simple. Suitable for all models of SF6 switches, GIS combination devices, vacuum switches, and oil switches produced domestically and internationally. Switch once to obtain all data and graphs. The host can store more than 10000 sets of current test data, with a real-time clock inside for easy archiving and saving of test dates and times.
Equipped with a USB interface, data can be directly saved to a USB drive. The host has a large screen, wide temperature range, background light LCD, full Chinese display of all data and maps, LCD contrast electronic adjustment, and power-off memory.

Product characteristics

Chinese menu operation, easy to use.
The all Chinese built-in printer prints all data and graphs.
Corresponding analysis software has been developed for the speed of just in and just out, which can be used to analyze and measure the speed of any type of switch produced by any switch factory at home and abroad as needed.
Definition of Terminology for High Voltage Switch Comprehensive Tester
The opening (closing) time is the time when the opening (closing) wire coil is powered on as the starting point for timing, until the time when the moving and stationary contacts are just opened (closed).
The difference between the maximum and minimum opening (closing) times within the same phase, same period, and same phase.
The difference between the maximum and minimum opening (closing) times of a three-phase synchronous system.
During the average speed opening (closing) process, 10% of the total stroke of the moving contact is removed from the front and back, and the middle 80% is taken. The ratio of the stroke of the moving contact to time is calculated.
During the maximum speed opening (closing) process, after the moving contact starts to move, a speed unit is taken every 10ms until the moving contact stops, and several speed unit values are obtained, among which the maximum unit speed value is the maximum opening (closing) speed.
The initial opening (closing) speed varies depending on the manufacturer of the tested switch and the switch model. Each manufacturer has defined different initial opening and closing speeds, and this tester includes various definitions for users to choose from.
10ms before and after closing: Partial oil switch and partial SF6 switch; 5ms before and after closing: partial oil switch and partial SF6 switch;
LW6 type: LW6 SF6 switch; LW8-35 type: LW8-35 SF6 switch;
10% to fracture: SF6 switches produced by Xi'an Switchgear Factory;
LW37-40.5: LW37 SF6 switch;
Same average speed: SF6 switches produced by Shenyang Switchgear Factory;
Customization: If none of the above definitions are adopted, users can define their own speed sampling segments for rigid opening and closing speeds based on the time travel curve measured by this tester (with directional travel). This tester automatically calculates the user-defined rigid opening and closing speeds (the ratio of travel to time within the sampling segment).
10mm before and after closing: Partial 35KV vacuum switch;
6mm before and after closing: Partial 10KV vacuum switch.
