DC high-voltage generators are widely used in power testing departments of power companies, mining, metallurgy, and iron and steel companies. Conduct high-voltage DC high-voltage tests on zinc oxide arresters, power cables, transformers, generators and other high-voltage electrical equipment. It is an important equipment for high-pressure test professional. The following principles should be followed for its selection and use:
1. The requirements for the manufacturer when selecting the type 1.1 The product should pass the type test 1.2 . The product should pass the network assessment organized by the relevant provincial Electric Power Testing Research Institute. No evaluation can be made. The results of the evaluation of other provinces can be found 1.3 . Standards, enterprise standards shall not be lower than the industry standard 1.4 , shall be a professional DC high voltage power supply manufacturer, have complete process equipment, inspection equipment and corresponding engineering and technical personnel, production personnel 1.5 , have a perfect after-sales service security system, preferably The agreement shows that companies must have a certain production scale
2. The technical requirements that should be put forward when ordering 2.1 The DC high voltage generator should be designed and produced with intermediate frequency modulation technology, and the boost type DC high voltage generator of the power frequency transformer should be prohibited from use.
2.2 , DC high voltage generator should have perfect moisture-proof and shockproof technical measures.
2.3 , DC high voltage generator should adopt advanced electromagnetic compatibility design, the whole machine can resist field-to-ground discharge impact.
2.4 , DC high-voltage generator should have a measurement of zinc oxide arrester automatic adjustment voltage 75% Function 2.5, DC high voltage generator should have over-voltage and over-current automatic protection device. In the event of abnormal operation, the automatic protection device should automatically shut down the DC high voltage generator.
2.6. The high-voltage terminal ammeter of the DC high-voltage generator shall have measures and capability of resisting electromagnetic interference and resisting forward and reverse impact, and the measurement uncertainty shall not be greater than 1.0%.
2.7 The display should have a backlit display. It should be clearly displayed within the scope of use. It is easy to identify and meet the needs of the site.

Audio Baby Monitor is also consist 1 mother unit and 1 baby unit, put the baby unit beside the baby, when baby cry or someone around the baby, you can hear the voice through the sound monitor. Beside, when someone want to do harm to baby, you will receive alarm in the audio monitor. Through this audio Baby Monitor, good baby heart monitor, your baby protected well.
more functions: Low power indicator; One way or two way communication, Communication range 300-800M; Emotional LCD.; Sensitivity Control. VOX voice activation; Rechargeable; Out of Range Alert.
