HIGH VOLTAGE REACTIVE POWER AUTOMATIC
COMPENSATION DEVICE YINGMING POWER
Features

◆ The device can be operated at steady-state overvoltage at 1.1 times the rated operating voltage;
◆ the device can be in the root mean value of not more than 1.3 times the rated current of the capacitor group over current continuous operation;
◆ device using vacuum contactor switching, can be frequent operation;
◆ Each capacitor has a discharge coil, in 5 seconds to the remaining voltage drop below 50V;
◆ Each capacitor can be relay protection or computer protection control unit, to achieve the capacitor group overcurrent, voltage imbalance, the system
undervoltage, overvoltage protection. When a group of capacitors in the event of failure, you can cut off the group of capacitors, does not affect the use
of other capacitors;
◆ single capacitor with spray fuse protection, each group is equipped with arrester from the operation of over-voltage and lightning overvoltage
protection;
◆ large-screen LCD controller, real-time display system voltage, current, power factor; with RS232 / RS485 standard communication interface, and can
achieve "four remote"
◆ Each group can be configured to suppress the closing surge or suppress the harmonic amplification.

Structure
◆ The drop-out fuse acts as a short-circuit protection and doubles as an isolating switch. The upper end enters the line from the high-voltage line, and
the lower end is connected to the surge arrester and the box;
◆ Lightning arrester for absorbing operation overvoltage;
◆ Seal the switch box, the top is the bushing for the incoming line, there are voltage transformers (for the power supply of vacuum switch operation
and voltage protection), current transformers, and vacuum contactors. Other controllers, indicator lights, etc. are installed in the control box, which is
isolated from the high voltage part;
◆ External capacitor type, there are outlet bushings on the side of the box, the capacitors are distributed on the side of the box, and they are connected
to this outlet bushing respectively. The top of the box is a rain cover, and there is a lifting ring for lifting. The switch box is installed on the platform
between the two poles, and the control box is fixed on the pole;
◆ Current transformer for sampling, install outdoor outdoor current transformer for phase A in the circuit.

The main technical parameters
◆ Rated voltage: 6-10kV;
◆ Rated frequency: 50Hz;
◆ Rated capacity: 100-10000kvar;
◆ number of groups: 1-5 groups;
◆ Reactor parameter selection: Suppression of closing inrush current, reactance rate of 0.1-1%; suppression of more than 5 harmonics, the reactance rate
of 6%; suppression of more than 3 harmonics, the reactivity rate of 12%.
