SVR Automatic step voltage regulator
■ Product profile
SVR automatic step voltage regulator automatically adjust the gear of on-load tap changer according to the condition of circuit voltage to realize the change of transformer ratio,so as to ensure that the output voltage is stable in a certain range.It can be widely used in power supply circuit with long distance of power supply,large power supply load,large voltage fluctuation and power quality can’t meet the usage standard.It can also be used in industrial and mining enterprises whose voltage quality can’t meet the production needs.The product has obtained national patent,the patent No.is ZL2010205818.4
■ Model description
■ Configuration & working principle
SVR automatic step voltage regulator consists of three parts:autotransformer,on-load tap changer and automatic controller.
■ Product features
1.The device adopts autotransformer structure,which has low loss and high efficiency.
2.Voltage regulate the width,obvious voltage regulation effect and high accuracy voltage regulation.
3.Automatic tracking of circuit voltage change,adjust the gear of tap changer,to realize on-load voltage regulation of voltage regulator automatically.
4.It can real-time display the circuit output voltage of the real time voltage,current,current gear,total operation times and daily operation times,set parameters and also can modify the set parameters.
5.With excellent control performance and communication function,realizing the"four remote"functions of telemetry,remote signaling,remote adjustment and remote control.
6.Small volume,large capacity,light weight,easy to install.
7.It has significant effect of consumption reduction and energy saving
8.High cost performance,high reliability.
■ Main technical parameters
The selection basis of voltage regulation range is as following:
The voltage at the input end of the voltage regulator is 9-11kv,and the voltage regulation range is-10%~+10%;
The voltage at the input end of the voltage regulator is 8.66-10.66kv,and the voltage regulation range is-5%-+15%;
The voltage at the input end of the voltage regulator is 8-10kv,and the voltage regulation range is 0~+20%.
The voltage at the input end of the voltage regulator is 7~10kV,and the voltage regulation range is 0~+30%
■ Installation method
The installation mode is outdoor installation,there are two installation modes.
If the capacity is less than or equal to 2000 KVA,the installation bracket can be used for double pole erection,and if the capacity is over 2000 KVA,the installation base is needed.Refer to the installation diagram as below:
