Detailed introduction

Main purpose and scope of application
TBBX high-voltage reactive power compensation device is connected in parallel with 6kV, 10kV high-voltage asynchronous motors to provide reactive current required for excitation to high-voltage motors to improve power factor, reduce the load on distribution transformers, and reduce lines And the loss of the transformer, improve the efficiency of the transformer equipment; have obvious energy saving, improve the effect of improving the starting and running performance of the motor; reduce the line loss and improve the voltage quality.
It is suitable for reactive power compensation of high-power motors in smelting, steel, mining, building materials, cement, water supply and drainage, and transportation industries. This product complies with: National Standard GB/T30841-2014 (our company is the main drafting unit of this standard).

Model and meaning

Working conditions
1. Indoor or outdoor use;
2. Altitude not exceeding 1000m;
3. Ambient air temperature -5°C~+40°C;
4. Relative humidity: daily average not greater than 95%, monthly average not greater than 90%;
5. There is no serious mold, no corrosive gas, no serious dust, no conductive dust, and no serious vibration at the installation site.

Main technical parameters
1. Rated voltage: 6kV, 10kV;
2. Rated frequency: 50Hz;
3. Rated capacity: 50-1000kvar;
4. Structure: cabinet type;
5. Capacitor wiring mode: star connection;
6. Working mode : Input as the motor works.

Product features
1. The products are divided into simple type and vacuum contactor switching type: the simple product capacitor is directly connected to the motor terminal through the fuse, the compensation device and the motor share a switching switch, and the compensation current does not exceed 90 of the motor no-load current %, so as not to damage the motor coils due to overvoltage caused by self-excitation after shutdown;
2. The vacuum contactor is used to switch, the motor switch is switched on, and the compensation device is also switched on; the motor switch stops working, the vacuum contactor is opened, and the capacitor is removed. The discharge coil automatically discharges;
3. The housing of the compensation device is made of cabinet profile combination or steel plate bending and welding. The upper part of the cabinet is the instrument door where the instrument is installed, and the lower part is the steel plate door with a safety lock inside the door;
4. The cable entry method of the compensation device: the cable entry method or the busbar overhead line entry method.
