FAQ

1)What types of sensors are available for the MEGK-W8006 High-Voltage Switch Dynamic Characteristic Tester? What are their respective application scenarios?

Answer: This instrument is equipped with two sensor types: rotary sensors and linear sensors. Their applicable scenarios are as follows:
Rotary Sensor: Suitable for scenarios where the linear transmission mechanism is enclosed within the switch body and no installation space exists for other sensors, or for factory testing by switch manufacturers on the opening/closing indicator or rotary shaft. During installation, ensure its axis is as concentric as possible with the switch's rotary shaft.
Linear Sensor: Suitable for scenarios requiring precise measurement of switch travel distance. Available in three specifications: 50mm (standard, for vacuum switches), 200mm, and 300mm (non-standard, for SF6 switches, etc.). Installation requires ensuring the sensor's motion axis moves linearly, with the pull rod moving parallel and synchronously with the switch's moving contact.

2)What are the core safety requirements for field wiring when using the MEGK-W8006 High-Voltage Switch Dynamic Characteristics Tester?

Answer: Core safety requirements are as follows:
Upon arrival at the site, the protective grounding terminal must be reliably connected to the site ground before proceeding with any other wiring or operations. After testing concludes, first turn off the instrument power, then disconnect all other circuits, and finally remove the grounding wire.
If the internal power supply of the instrument is used for closing/opening control (internal trigger mode), the control power supply within the switch control box under test must be disconnected (without disconnecting the energy storage power supply). The internal power supply of the instrument must not be used as the power source for the on-site energy storage motor.
During wiring, avoid contact with exposed circuits and live metal parts. It is strictly prohibited to arbitrarily plug or unplug test leads while they are connected to live terminals.

3)What core functional modules does the main menu of the MEGK-W8006 High-Voltage Switch Dynamic Characteristics Tester include? What are their primary functions?

Answer: The main menu comprises five core modules: [Settings], [Test], [View], [File], and [Help], with the following functions:
[Settings]: Configure pre-test parameters including speed definition, sensor installation phase, test duration, trigger mode, test voltage, etc., to ensure instrument operation aligns with requirements.
[Test]: Executes various test operations, including single-close/single-open tests, close-open/open-close/open-close-open tests, low-voltage operation tests, and manual multiple-close-open tests.
[View]: Post-test analysis and result review, displaying curve graphs, comprehensive data, bounce processes, and waveforms. Supports speed analysis and result printing.
[File]: Stores test data and retrieves archived records. Data is categorized by date and can be permanently saved.
[Help]: Provides instrument intellectual property details, software version, factory serial number, and company after-sales contact information for user inquiries.
