TBBZ automatic switching type high voltage reactive power compensation device (hereinafter referred to as TBBZ automatic switching device) is applicable to power system and industrial and mining enterprises 35kV、110kV substation, 6kV, 10KV voltage level enterprise distribution station, new and expanded parallel capacitor device in all levels of power transformation and distribution network, TBBZ automatic switching device can improve the quality of power supply voltage to the greatest extent by selectively controlling the operation of capacitors, Adjust the power factor of the power grid, reduce the power loss, and ensure the safe and reliable operation of the device itself and the related power grid.

The device composed of high-voltage shunt capacitor, capacitor cabinet or metal frame, fuse, discharge device, series reactor, post insulator, arrester, disconnector, grounding switch, circuit breaker and connecting bus is called high-voltage shunt capacitor device (hereinafter referred to as "device"), and its performance conforms to GB / T 30841-2014 "general technical requirements for high voltage shunt capacitor device" and "code for design of high voltage shunt capacitor device" (GB 50227-2017).

Feature:

TBBZ automatic switching high-voltage reactive power compensation device is another main product of our company after the complete set of TBB high-voltage shunt capacitor. It is a static compensation device with dynamic regulation.

(1) In order to respond to different reactive power requirements under different loads, capacitors are grouped according to capacity; appropriate automatic switching control device and special switching switch are selected, When the joint control of reactive power compensation and transformer voltage regulation is needed, the VQC controller is selected to more precisely adjust the voltage and reactive power demand and control the power quality;

(2) The equipment can be switched on and off with equal capacity, unequal capacity and cycle to prolong the service life of the equipment;

(3) The electromechanical integrated protection device is installed in various protection methods to protect the safety of personal equipment;

It can be configured with over-current, quick break, over-voltage, under voltage, open delta voltage, unbalanced current at the center point, phase voltage differential, voltage harmonic distortion and other relay protection;

(4) The control device adopts Chinese liquid crystal operation interface, has remote control interface and communication interface with upper system, and can communicate with the central control system of transformer station.

(5) The device has novel structure design and beautiful appearance, Users can choose the form of armored combination cabinet and frame fence.

Model# introduction

The model consists of 7 parameters:

1. Complete set of device: TBBZ is supplied in the form of complete set;

2. Parallel capacitor: the device belongs to parallel capacitor device, which conforms to the design code of GB50227-2008;

3. Automatic control: refers to one or all of automatic switching control, automatic protection control and remote control;

4. Voltage level: 6 and 10 can be selected, unit kV;

5. Group capacity: refers to the capacity grouping of all capacitors in the device, unit: kvar;

6. Single capacity: the capacity of a single capacitor, unite: kvar; when there is more than one type of single capacity, it can be listed in brackets.    

7. Endnote number: the endnote number is composed of two characters, the first character indicates the connection mode:

A: single star connection

B: double star connection

The second character indicates unbalanced protection mode

K: open delta zero sequence voltage protection

L: neutral point unbalanced current protection

C: phase difference dynamic voltage protection

Example: TBBZ10 - (1200 + 1200 + 1200) / 200ak, which means TBBZ automatic switching high-voltage reactive power compensation device with voltage level of 10kV, The total capacity is 3600kvar, which is divided into three groups of 1200 + 1200 + 1200. The single capacitor of 200KVA is selected, the single star connection is made, and the open triangle zero sequence voltage unbalance protection is adopted.
