730TBB

730TBB is a three-phase unbalanced distribution automation system developed by Shenzhen Kaiguan Technology Co., Ltd. It is suitable for the automation of urban substations with a rated voltage of 10kV and a rated current of 630A. It has a wide range of applications in the field of urban power distribution automation, and can realize complete automation control of single and double breaker substations.

The 730TBB system consists of monitoring, control, communication and power equipment, and can provide functions such as equipment supervision, information publishing, electricity load pre-distribution, fault alarm indication, fault location and automatic switching. It can also provide diagnostic functions for three-phase unbalanced, six-phase unbalanced networks, as well as nine-phase unbalanced network systems.

The 730TBB system uses various techniques to achieve the smooth operation and accurate performance of the system. It is equipped with self-adaptive control, which can automatically adjust the parameters in the system based on the actual conditions of the field. The working principle of 730TBB can be summarized as follows:

1. Electricity load pre-distribution: The system continuously detects the current, voltage, power factor and other states of the guided electric field equipment, and automatically redistributes the current load of the line in accordance with the set parameters to optimize the system operation.

2. Fault alarm indication: The system can accurately detect, judge and indicate the faults such as line faults, short circuit faults and overvoltage presses, and automatically switch off the specified lines to realize the self-protection of the system.

3. Fault location: The system accurately locates faults and completes fault switch off as soon as possible to accelerate the fault repairing process and reduce the losses caused by the faults.

4. Automatic Switching: In the case of an emergency fault, the system can automatically switch off the faulty line and restore the system to normal operation. It can also provide accurate fault location data to the operator for the purpose of rapid fault detection and repair.

The 730TBB system is an ideal choice for the automation of urban power distribution control systems and can provide reliable, accurate and real-time operation data, which is of great help in improving the safety and efficiency of power distribution.
