Product Description

High Voltage Switch Mechanical Characteristics Tester

DARUI Electric recommends:

The High Voltage Switch Mechanical Characteristics Tester is based on a high-performance industrial embedded platform, featuring high-speed data acquisition and analysis processing capabilities. It can resist strong electromagnetic field interference (above 500KV) and has the characteristics of simultaneous analysis of multiple high-voltage switch dynamic characteristics and high testing accuracy.. For different testing requirements of different switches, the instrument has rich and perfect user-defined functions. The instrument has a built-in isolated adjustable DC power supply and a switch operation command simulation control module. During the test, the switch can be directly controlled for opening, closing, and reclosing operations through the built-in DC power supply, with automatic or manual action voltage test functions. The instrument can test and analyze various mechanical characteristic parameters (time, speed, synchronization, travel, bounce, coil current, etc.) of various types of high-voltage switches.

Introduction:

Wuhan Zhongshi High Voltage Switch Mechanical Characteristics Tester applies photoelectric pulse technology, microcontroller technology, and reliable anti-electromagnetic radiation technology, equipped with precise and reliable speed/distance sensors. The main feature of the High Voltage Switch Mechanical Characteristics Tester is the use of human-machine dialogue operation and Chinese printing of measurement results. It is suitable for testing the mechanical characteristics and related parameters (time, synchronization, bounce, speed, travel, etc.) of various types of high-voltage switches (vacuum, multi-oil, low-oil, SF6, etc.) manufactured by different manufacturers.

Instrument Features

>Can perform electric and manual operations

>Suitable for mechanical dynamic characteristic testing of various high-voltage circuit breakers within 500KV voltage level

>Can measure actual travel and custom travel

>Can realize single close, single open, close-open, reclose, and re-open operations of circuit breakers

>Convenient wiring and simple operation. Only one close (open) action is needed to obtain all data of close (open). Can choose to save 50 sets of data, provide later query and upload to computer for permanent storage, and can also view and print all data and motion curve diagrams on site

>Built-in clock circuit can display current year, month, day, hour, minute, and second. Even if power is off, it can automatically save setting data and test data

>Built-in delay protection function. After the circuit breaker operates, it can automatically cut off the action power supply, well protecting the circuit breaker equipment and the high-voltage switch tester

>The instrument has a built-in DC power supply with selectable range: 30-270V/10A. There is no instantaneous voltage drop at the output of conventional rectifier power supplies, making it very accurate for testing switch action voltage

>Can dynamically analyze the relationship between travel and speed of the circuit breaker every 1ms

>Can be configured with upload software to achieve computer archiving, online viewing, and printing.

Can test any model and type of circuit breaker
