Product Overview

With the rapid development of the national economy, an increasing number of oil-filled power equipment, such as transformers, are being installed in remote areas far from urban centers. When these large transformers exhibit abnormalities requiring continuous monitoring and testing, sampling followed by laboratory analysis not only compromises the timeliness of the data but also entails substantial expenditures of human and material resources.

The MCC-9580 portable chromatograph specially designed for transformer oil is the latest portable gas chromatograph launched by Hubei MECI Electric Power Equipment Co., Ltd., which is suitable for rapid on-site analysis. This instrument adopts the classic three-detector configuration, allowing complete analysis of dissolved H in insulating oil with a single injection. 2 , CO, CO 2 , CH 4 , C 2 H 4 , C 2 H 6 , C 2 H 2 A comprehensive analysis of the concentrations of seven gaseous components was performed, and the analytical results were in complete agreement with those obtained using conventional laboratory gas chromatographs. The instrument incorporates an advanced compact modular design, resulting in a small footprint and light weight, which facilitates on-site deployment for field analysis. This not only provides timely and accurate data for transformer condition monitoring but also significantly reduces labor and material resources.

The MCC-9580 portable chromatograph specially designed for transformer oil is suitable for both field and laboratory analysis. With further improvements in its overall technology and design, it has emerged as a viable alternative to laboratory-based chromatography systems and has now been successfully deployed across a wide range of industries and organizations, including power supply companies, power plants, transformer manufacturers, large-scale smelting enterprises, and railway power supply sections.

 

 

 

Product Features

1. Employing computer-based feedback control technology to achieve digital display of instrument gas-path pressure:

All gas-line pressures in the MCC-9580 are digitally displayed via pressure sensors, allowing direct reading of carrier gas, hydrogen, and air pressures from the workstation to facilitate precise control of analytical conditions.

2. Employ computer-based remote control technology to enable instrument temperature setting, display, and other operations:

All temperature parameters of the MCC-9580 are digitally displayed, allowing direct reading and control—via the workstation—of temperatures in all zones, including the column oven, detectors, and converter furnace, with simple and intuitive operation.

3. Employ computer-based remote control technology to enable one-button power-on:

All operations for MCC-9580, including heating and cooling, can be performed with a simple mouse click on the workstation, completely eliminating the cumbersome procedures previously required in laboratory chromatography and essentially enabling one-click startup.

4. Simply click the mouse to complete operations such as ignition and current settings.

The MCC-9580 is equipped with an automatic gas-flow control system that, with a single mouse click, automatically vents a portion of the carrier gas to adjust the hydrogen-to-air ratio to the optimal ignition setting and then restores this ratio once ignition is complete. Similarly, the thermal-conductivity bridge current can be set via the bridge-current configuration window in the workstation software.

5. Digital FID electronic zeroing technology enhances the instrument’s anti-interference capability:

The FID detector signal of the MCC-9580 employs electronic zeroing, utilizing high-precision digital circuitry to compensate for the FID’s baseline current and thereby achieve electronic adjustment of the FID output signal level. Because this electronic adjustment can be implemented directly on the signal path of the circuit board, it enhances suppression of electronic noise and eliminates interference signals that may arise from mechanical potentiometer wiring. Furthermore, by reducing parasitic parameters, the system exhibits strong immunity to electromagnetic interference.

6. Employ computer-based feedback control technology to achieve control of the oscillator.

Via a single connection signal cable, the MCC-9580 can supply power to a compact oscillator and enable full-process operation control from the workstation, including heating, start-up oscillation, pause, and buzzer alerts at the end of the cycle.

7. Built-in silent air pump—no external air supply required:

The MCC-9580 host unit is equipped with a compact, imported air pump that provides a continuous supply of compressed air to the instrument. Thanks to its vibration-damping design, the air pump operates virtually silently, so users hardly notice it at all.

8. Thermal Conductivity Tungsten Filament Gas Breakage Protection Function

The MCC-9580 features intelligent thermal conductivity gas-cut-off protection: when the carrier gas pressure falls below the safety threshold, the system automatically shuts off the thermal conductivity current to prevent damage to the thermal conductivity detector.
