Product Description

Switchgear Circuit Breaker Analyser Circuit Breaker Dynamic Characteristic Analyzer

 

Circuit Breaker Analyzer General Introduction:

The GDGK-307 High Voltage Switch Dynamic Characteristics Circuit Breaker Analyzer is a dedicated device designed for field measurements of the mechanical properties of high-voltage circuit breakers. At its core, it utilizes an industrial computer for sampling and processing, coupled with a large LCD display and full touch-screen control for an intuitive user experience. Equipped with an extensive database, the analyzer boasts high intelligence, comprehensive functionality, and precise data output. It also features robust anti-interference capabilities, user-friendly operation, compact dimensions, and a lightweight design. The GDGK-307 is well-suited for the dynamic characteristic testing of a variety of circuit breakers, including oil-filled, vacuum, and SF6 types, making it a versatile tool for both indoor and outdoor applications.

Circuit Breaker Analyzer Features:
 

The device is designed for a range of measurements, including closing time, opening time, time spread between poles, and other parameters related to the operation of the circuit breaker.

It also measures various aspects of the circuit breaker's speed, clearance, resistance, and vibration, as well as other performance indicators such as pre-insertion resistance and contact resistance.

The device has a 12.1-inch touch screen for easy control and data input and a built-in micro printer for test result printouts.

It can generate WORD format test reports automatically, and all reports and data can be exported through a Flash disk.

Additionally, the device offers features such as zoom, editors, statistics, and analysis for measurement curves, making it a comprehensive tool for circuit breaker testing and analysis.
