The A1220 Insulation Oil Gas Chromatography Analyzer is designed and manufactured according to the methods specified in GB/T 17623 and DL/T 703 standards. It is suitable for analyzing the content of gases such as hydrogen, carbon monoxide, methane, carbon dioxide, ethylene, ethane, acetylene, etc. dissolved in insulation oil in oil charging equipment (including transformers, reactors, current transformers, voltage transformers, charging sleeves, etc.).

Main technical features and parameters

1. Realize real-time computer control and data processing:

The instrument comes with a digital interface, which enables real-time data signal acquisition, data processing, and detection results on the computer through a communication cable. The instrument computer is connected to the Internet and can be connected to the instrument through a remote computer to realize remote data collection and management. Improved the degree of freedom of the device and promoted its effective application in the laboratory.

Through a user-friendly software interface, it is convenient for users to set parameters including temperature, range, detector, bridge current, etc; Intuitive operation includes functions such as FID ignition (previously fully automatic, no manual operation required), switching bridge current, opening and closing temperature control, and various time events;

2. High precision, stable and reliable temperature control system:

The main control circuit adopts advanced microprocessors and large capacity memory to make data storage more reliable; The integrated design of measurement, control, and circuit board simultaneously improves the anti-interference and reliability of the instrument; Using a temperature control circuit with a microprocessor, the temperature accuracy of the controlled objects in each heating zone reaches 0.1 degrees;

The column box is equipped with an over temperature protection device. If any temperature exceeds the set limit, the instrument will stop heating and report the faulty area on the display;

3. A concise and clear human-machine dialogue interface, easy to operate, easy to learn and use

The instrument adopts a large screen LCD display with Chinese characters, which is intuitive and easy to operate;

Self diagnostic function, able to display the location of the fault;

Data power-off protection function, the operating data set by the instrument can be saved for a long time after power failure;

Equipped with stopwatch and counting function

4. Double stable high-precision pneumatic control system.

The carrier gas path adopts a dual stable gas path system of first stabilizing the pressure and then stabilizing the flow

The flow control valve adopts knob adjustment, which is intuitive and reliable.

Equipped with an electronic pressure display system, the accuracy is higher than that of a pressure gauge.

5. The column chamber adopts a tracking heating method.

6. The instrument can detect low levels of hydrocarbons and high levels of CO and CO2 separately to avoid mutual interference.
