In their daily work, electric power workers often need to use SF6 gas detector to detect SF6 equipment and judge the insulation performance of these SF6 equipment. After a long time of use, SF6 gas will have various kinds of faults, and there are also many problems to pay attention to. So what are the troubleshooting methods and precautions of SF6 gas leak detector? This article gives you a brief introduction.
Common faults and handling methods of SF6 gas leak detector:
1. If the test hose is cracked or damaged, just return the test pipe and hand-held probe to the factory for repair.
2. When testing the concentration of sulfur hexafluoride gas, if the instrument has no corresponding test value or the test concentration is low, try to press the key on the front panel of the host machine, start the diaphragm pump, and form the air extraction flow. Read whether the test value returns to normal after 10 seconds. After starting the diaphragm pump, press the air inlet of the test handle by hand, and feel whether there is obvious negative pressure. If there is no negative pressure, please clean the test port to see if there are pollutants blocking the test port. If the above two solutions still cannot solve the problem, please return to the factory for maintenance.
3. After the switch is turned on, the instrument cannot be turned on, shut down, and use the charger to charge the host for 30 minutes. For example, restart after 30 minutes. If it still does not operate, return to the factory for maintenance.
Precautions in the use of SF6 gas leak detector:
1. During the test preheating, please place the test probe in the air without sulfur hexafluoride gas.
2. Please do not block the test port of the hand-held probe for a long time.
3. It is forbidden to send oil, liquid water, strong acid and strong alkali gas into the test port of the instrument to avoid damaging the instrument. The instrument damage caused by this condition shall be repaired according to the price of the replacement device, without warranty.
4. It is forbidden to use hard objects to hit the display screen.
