Low Voltage Inactive Automatic Compensation Equipment
Introduction - Automatic Compensation EquipmentZGW ( )-0.4/□Low Voltage Inactive Automatic Compensation Equipment is one of the series of low voltage equipments which is designed by the national electric network construction and power departments on the basis of safe, economical, reasonable and reliable. It is widely used in the power distribution system of 50 Hz rated frequency 30-90kvar rated compensation capacity and 400V rated voltage to improve power factors and power supply quality as well as reduce the energy power loss.
Working & Environmental Conditions - Automatic Compensation Equipment
1. Environmental temperature: maximum +50°C, minimum:-25°C
2. Altitude≤2000m
3. maximum temperature difference: ≤35°C
4. Installation Conditions: no dangerous gas or steam, no conductive or explosive dust, no dramatic shake
Features - Automatic Compensation Equipment
1. Automatically designs capacitor switching in accordance to inactive requirements, such as phase, rank, cycle switching. Each maximum level is six.
2. The controller has “△+Y” output which is of high compensation accuracy and good effects. It can monitor the power distribution.
3. The switch adopts composite solid relay without triggering electrocution, surging current or electrical arc. It has a rapid response speed, long life span and would not give out heat during operations.
4. It adopts new type low voltage self-healing capacitor which has internal self-discharge function, small volume and high reliability. If the power was cut, the voltage can reduced to below 50V from the peak value in three minutes.
5. The device can instantly connect to the power after the power failure to prevent the capacitor operation.
6. The device can measure the Bailey wave distortion rate of the installation point. When it is over the preset value, the device would alarm.
7. It can configure remote data communication interface which can achieve remote monitoring and data collection by GPRS module. It can also install the WDM-1 wireless adapters produced by our company which can realize data wireless copy.
