DC Disconnectors Receiving Inspection
Check the received goods and verify whether the model, specification and quantity DC switch disconnector (hereinafter referred to as disconnector) are the same as the ordered goods. When opening the wooden packing box for inspection, avoid bruising the disconnector and damaging the package. It is recommended to keep the wooden packing box until installation and use. After carrying out an inspection of the goods received, even if it will be installed and used in a short time, please still put the disconnector back into the package, taking care to protect it from water and moisture. If any damage or abnormality is found during the inspection, please contact us within 5 days after receiving the goods.
- The storage environment shall be dry, dust-free, and free from corrosive and explosive chemicals.
- Please place the disconnector horizontally on any fixed parts, no directly on the ground.
- During storage and transport, the disconnector shall be in disconnected state and the spring mechanism in the energy release state.
- During moving for installation, take care to protect the disconnector and personnel; Tipping, hitting or dropping may lead to damage to the disconnector.
- Electric energy storage: When the disconnector releases energy, if the electric energy storage mechanism is energized, the energy storage motor will automatically store energy to the disconnector operating mechanism, and the motor will stop automatically when the energy storage is finished, and a clicking sound can be heard, at this time the panel "energy storage/release" indication is in the storage state.
- Underclosingstatus, press the opening button on the panel or energize the shunt release to hear the "bell" sound. At this time, the "I / O" indication window on the panel indicatesas"O", meaning that the disconnector has been disconnected. At this time, the energy release of the disconnector operating mechanism is completed.
- Manual energy storage: similarly, the manual energy storage handle can be pressed to store energy; Press down for about 6 or 7 times, hear a click, and the reaction force of pressing down the handle decreases obviously. At this time, the "energy storage / energy release" indication on the panel is in the energy storage state, indicating that the energy storage is completed.
- In the case of energy storage, press the closing button or energize the closing electromagnetic iron, and you will hear the "bell" sound. At this time, the "I / O" indication window on the panel indicates as"I", meaningthat the disconnector has been closed. At the same time, the "energy storage / release" indication on the panel is in the energy release state. At this time, if the energy storage mechanismis still powered on, the energy storage mechanism will automatically store energy for the operating mechanism of the disconnectoragain. After energy storage, the motor will stop automatically, and the "energy storage / release" indication on the panel isin the energy storage state.
