Product details
Overview
Â
Reactive power compensation ZRTBBG type high voltage reactive power on-site compensation device (hereinafter referred to as the device) is an indoor cabinet with rated voltage of 6-10kV and frequency of 50Hz, which is widely used for on-site reactive power compensation of three-phase AC motors with fixed voltage of 6-10kV. In order to reduce power loss, improve the quality of grid voltage and improve the motor start performance.
The biggest characteristic of the compensation device is that the capacitor bank is put in when the motor starts and cut out when it stops. It's a big effect,
Superior to centralized compensation of novel energy-saving products.
Â
Implementation of standards
Â
GB 50227-2008 "Code for design of shunt capacitor Devices"
JB/T 10557-2006 "High voltage reactive power on-site compensation Device"
DL/T 604-1996 "Technical conditions for ordering high voltage Shunt capacitor Units"
Â
Model number and its meaning
Â
Â
Service environment conditions
Â
1. The altitude of installation and operation area shall not exceed 1000m;
2. Indoor use
3. The ambient air temperature in the installation and operation area ranges from -40℃ to + 55;
4. The installation site is free from serious mold, corrosive gas, serious dust and conductive dust, the space is well ventilated, and there is no serious mechanical vibration. The device should not be exposed to strong electric and magnetic fields.
5. Relative humidity: daily average ≤ 95%, monthly average ≤ 90%;
Â
Structural characteristics
Â
1. The shell of the compensation device is composed of a combination of cabinet profiles, bending welding of steel plates or assembling by bending aluminum-zinc plates.
2. The wiring mode of the assembly weight can be lower than the wiring mode of the electric system, overhead wiring mode of the bus bar, or according to the user's agreement.
Â
Features of the device
Â
1. The device is in parallel with the main motor, which is put in when the motor starts and cut off when it stops. There is no need to set special switch for switching and cutting.
2. The device has a variety of structure types, large or small capacity, can be single screen or multiple screen combination, flexible selection, wide application, make Easy to use and maintain.
3. The resetting is heavier than the motor end, and the compensation effect is the best, which can greatly reduce the operating current capacity in the switch and circuit, and reduce heat and decrease less trouble.
4. As the reactive current of the motor is greatly compensated, the loss is reduced, the voltage quality is improved and the starting characteristic of the motor is also improved.
5. Simple structure, less investment, quick effect and so on.
Â
Main basic parameters
Â
1. Rated voltage: 6~10kV
2. Rated capacity: See the basic parameter table for rated capacity.
3. Rated current: See the basic parameter table for the rated current.
4. Connection mode of compensation device
The wiring mode of the compensation device is Y-shaped, and the neutral point is not grounded.
5. Typical basic parameter table of local compensation device
Â
6kV capacitor compensation parameters table table 1
10kV capacitor compensation parameters table table 2
Â
Protection and anti-error function
Â
1. The compensation device is a star (Y) connection, and a single shunt capacitor protection fuse is used as the main protection of the device. Overcurrent, overvoltage, and undervoltage protection are shared with host protection. The capacitor uses internal double discharge resistance, when the device is cut, independent of external conditions can effectively self-discharge and meet the specified requirements.
2. The front and lower doors of the device are equipped with electromagnetic lock and latching switch, which are interlocked with the host switch respectively. The front and lower doors of the device cannot be opened when the main engine is in operation. The front and lower doors can only be opened when the main engine is completely stopped. In this way, the normal and safe operation of the device can be effectively guaranteed. On the other hand, when the front and lower door of the device is not closed, the host switch (or the starting device) can not be opened, it is necessary to close the front and lower door of the device to make the host open, effectively prevent entering the inside of the live device.
