At present, the drip test device used in drip test is limited by the difficulty and cost of structural layout, so it is difficult to actively rotate the electrical equipment with large volume and weight, and can not meet the test requirements of various products. In view of the defects of the existing technology, this paper provides a water-proof performance drip test device, system and method. Through the active rotation of the drip pan, the rotation relative to the large-scale test equipment is generated, so as to meet the needs of the equipment waterproof performance test; and the corresponding equipment support is configured to make the equipment form the required angle state during the dripping test, which is convenient for large size Water proof test operation of electrical equipment. At the same time, it makes the test process easy for the staff to operate, has strong economic value and social significance, and can be widely used in testing units.
Abstract. On 8 November 2013, super typhoon Haiyan made landfall in Philippines. On 24 November, the Chinese hospital ship arrived in Philippines to help with disaster relief efforts. Drinking water was collected at a variety of locations, and the concentration levels of lead were determined with field test kit. The results showed that the levels of lead in 67% of total collected water samples exceeded WHO's standard. Afterwards, the local government had taken many measures to ensure a safe water supply in next few months. This is the first report about water quality in Philippines after the disaster.
