Introduction: The dry powder electrical insulation tester is designed and manufactured in accordance with the electrical insulation requirements of the national standard GB4066.1-2004 dry powder fire extinguishing agent general technical conditions. Used to test the electrical insulation of dry powder fire extinguishing agents. Components of the dry powder electrical insulation tester: This instrument consists of a voltage test bench, a test cup, an electrode, and a drop test bench. Technical Parameters: 1. Test cup: The test cup has a pair of disc-shaped flat electrodes mounted on the same axis, and the cup body is made of non-hygroscopic, highly insulating material. The distance between any part of the disc-shaped electrode and the test cup is not less than 13mm. The distance between the top of the test cup and the top of the disc-shaped electrode is not less than 32mm. The test cup can be disassembled, cleaned and polished, and the distance between the two disc-shaped electrodes can be adjusted. 2. The disc-shaped plate electrode of the dry powder electrical insulation tester is made of polished brass plate, the diameter is 25mm, the thickness is not less than 3mm, and the edges are at right angles: the distance between the two electrode plates is 2.50±0.01mm 3. Withstand voltage test part of dry powder electrical insulation tester, voltage 0-10Kv; current output 0-20mA; digital display 4. Dry powder electrical insulation tester drop test bench: drop height 30mm * maximum allowable load 50kg, frequency range 0-1.667Hz continuously adjustable, falling acceleration greater than 9.3m/s^2. 500 times of drops make the dry powder fire extinguishing agent sample compact.
