Description
Structure and features
Automatic Transfer Switch,is composite by 2PCs 3P or 4P mini circuit breaker,mechanical chain transmission mechanism,controller,etc,the feature will be as follows:
1.Small in volume, simple in constitution; there is provide 3P,4P. easy to operation and long to use.2.Transfer switch driving by single motor,a smooth,no noise,the impact is small.3.With mechanical interlocking and electrical interlock,change over credibility,could be supply by manual or automatic operation.4.Have the short circuit,overload protection also the over voltage,under voltage,loss phase function and also the intelligent alarm function.5.Automatic switching parameters can be freely outside.6.With computer network interface for remote control,remote adjustment and remote communication,remote sensing and other four control function and so on.Working conditions
1.Ambient air temperature of -5ºC
to +40ºC,and at 24 hour average temperature does not exceed +35ºC.2.The installation location no more than 2000 meters.3.The maximum temperature of +40ºC,the air relative humidity is no more than 50%,at a low temperature can be allowed to have a higher relative humidity,such as 20ºC
at 90%. special measures should be taken for occasional condensation due to temperature changes.4.Pollution level:grade
3
5.Installation category:3.6.The two power lines are connected to the upper side of the switch,and the load line is connected to the lower side.7.The location of installation should not have significant vibration,impact.Supplementary explanation1. in special circumstances, manual mode can be used to switch between common or backup power sources
2. Can be used for single-phase AC220V power supply circuits, and the two power sources can be mains power generation Machine solar power generation, street light electricity, batteries, etc., if it is DC or low voltage The power supply needs to be reversed by an inverter to AC 220V before being connected to a dual power supply
3. Switching is not a backup power source, that is, it cannot replace batteries
4. Rail installation
