Abstract: In order to verify whether the low-voltage switchgear meets the requirements of IPX1 and IPX2 protection grades, a drip test device simulating atmospheric rain is designed. This device mainly uses load-bearing steel structure stable frame test-bed, intelligent remote control system, anti blocking dripping needle plate, etc. the load-bearing steel structure stable frame test-bed meets the load demand, the anti blocking dripping needle plate maintains water quantity and water flow efficiency, the intelligent remote control system stably adjusts water quantity and platform optional angle, and combines with PID control algorithm for feedback adjustment. The test results show that: the device realizes the IPX1 and IPX2 level test of large low-voltage switchgear, which is reliable and efficient, and meets the test requirements in GB/T 4208—2017“ Shell protection class (IP code)”.
Key words: dripping test; large-scale low-voltage switchgear; protection class
