10kv series capacitor complete set device
Shaanxi Sefon Electrical Equipment Co.,Ltd.is a high-tech enterprise specializing in the R&D,production and sales of power quality and energy-saving intelligent electrical equipment.With the independent intellectual property rights,the company has successively launched voltage regulator devices,high and low voltage reactive power automatic compensation devices,high and low voltage reactive power filter,which solves the power quality problems of voltage,reactive power and other problems in the power system.Today,we introduce the application and features of 10kV series capacitor complete set devices:
(1)Profile
10kV series capacitor is used in 10kv AC power frequency of power system.It is usually parallel installed in distribution circuit to improve the terminal voltage of circuit.
The device is mainly consists of primary device such as cabinet,series capacitor,fast switch,isolating switch,voltage transformer,current transformer,damping reactor,damping resistance,metal oxide arrester and secondary device such as controller.The device is highly integrated,safe and reliable,and easy to install.
(2)Usage
The complete set of 10kV series capacitor is parallel connected in 10kV circuit.Its main function is to make use of the capacitive reactance of the series capacitor to compensate the inherent inductive reactance of the circuit,so as to reduce the circuit impedance,reduce the circuit loss,improve the voltage quality and the terminal voltage of the user,and improve the transmission capacity of the circuit.
(3)Device features:
■The device is of integrated design,compact structure and easy installation.At the same time,the device is arranged in a cabinet on a pole with small floor area.
■The device has its own secondary power supply,which is easy to access.
■The device is safe and reliable,with various protection methods of over current protection,over voltage protection,phase failure protection etc.
■The device has a backstage test service website,which can realize remote communication and check the operation of the device with mobile phone or computer.
■It is use internal fuse capacitor,with simple wiring and reliable protection.
■Capacitor bank switching adopts fast switch,with short response time and fast switching speed.
■The cabinet body is made of aluminum coated zinc plate by spraying plastic,which can ensure no rust for 30 years.
