Ash Density Measuring Instrument |
1. Product Introduction
GWJ-3000 Insulator Ash Density Tester is a complete set of measuring device for "ash density" developed by our company according to the needs of anti-pollution flashover work in China's power grid and the new standard for pollution level classification of power grid. This device complies with GB/T 16434-2004 "Selection and dimensioning of high-voltage insulators intended for use in polluted conditions - Part 1: Definitions, information and general principles" (replacing GB/T 16434-1996, GB/T 5582-1993, JB/T 5895-1991) and the requirements of State Grid Corporation's Q/GDW 152-2006 "Classification of environmental pollution areas for high-voltage overhead lines and substations and selection standard for external insulation".
GWJ-3000 Insulator Ash Density Tester is a complete measuring device. It includes precision electronic balance, forced air drying oven, vacuum filtration unit and measuring accessories. The whole device is easy to operate and provides accurate measurement.
2. Functional Features
1. The vacuum filtration device has mature technology, is convenient to use, and has high efficiency. It contains multiple suction heads, allowing multiple filtration processes at one time. The use of a water circulation device instead of an oil circulation pump makes it more convenient and reduces failure rate.
2. The forced air drying adopts German technology with advanced air duct; the fan has low noise and stable performance.
3. Microcomputer intelligent control: after setting the temperature, the instrument automatically determines the required heating power and displays the heating status, ensuring stable and accurate temperature control.
4. Adjustable air inlet to control the temperature inside the box and the discharge of gases.
5. The high-precision electronic analytical balance has multiple functions such as digital multi-point linear correction, drift correction, power-on self-test, and tare.
6. Comes with supporting calculation software, making calculation convenient and results more accurate.
