Embodiment 1

[0041] The embodiment of the present invention provides an uninterrupted power regulation device, which can be applied to a power distribution room powered by dual power sources such as 10kV and 24kV and without access to distributed power sources. It has the functions of bus coupler fast switching under fault status, incoming line fast switching function and "one-button sequential control" function during normal operation, which can realize the continuous power operation of industrial loads and domestic loads, that is, the production line does not stop, the car does not stop, the light bulb It does not go out, the computer does not restart, and the motor does not stop. In addition, the uninterrupted power regulation equipment can realize dual power supply without disturbance and non-perceptual power regulation, which has a significant improvement effect in the later distribution network application. Based on the advantages of fast switching, there is no need for power failure ...

Embodiment 2

[0090] The embodiment of the present invention provides an uninterrupted power regulation system, such as Figure 7 with Figure 8 As shown, the uninterruptible power regulation system includes: dual power supply equipment 700 and the uninterruptible power regulation equipment 800 described in Embodiment 1, the dual power supply equipment 700 is connected to the uninterruptible power regulation equipment 800, and the dual power supply equipment 700 A double-feeder high-voltage power supply distribution room consisting of a main feeder and a backup feeder; wherein, the main feeder is provided with a main power supply for supplying power to the bus section I (abbreviated as I bus in the figure); the backup feeder is provided with a backup power supply, It is used to supply power to section II of the busbar (abbreviated as II bus in the figure).

[0091] Specifically, the dual power supply equipment 700 includes a double feeder 10kV high-voltage power supply distribution room co...

Embodiment 3

[0129] Such as Figure 9 with Figure 10 As shown, the embodiment of the present invention also provides a non-stop power regulation control method, based on the non-stop power regulation system described in the second embodiment, including the following steps:

[0130] S101: The intelligent controller is connected to the mains, the power module charges and stores the energy for the energy storage capacitor module, and waits for the switching signal of the quick switching device.

[0131] Specifically, when the intelligent controller receives the switching signal (opening and closing instruction) of the fast switching device, the intelligent controller controls the energy storage capacitor bank to output the opening and closing current to the mechanism coil of the circuit breaker according to the opening and closing instruction, so that The circuit breaker performs opening and closing actions. Otherwise, continue to wait for the switching signal of the fast switching device....

Abstract

The invention provides an uninterrupted power conditioning device, a system and a control method, relating to the technical field of electrical engineering. Fast power supply switching is realized. Operation interruption or device impact damage during power supply switching is avoided. The switching operation is simplified, and operation error is reduced. Continuous operation of loads with power uninterrupted is ensured. The uninterrupted power conditioning device comprises a circuit breaker, an intelligent controller, and a fast switching device. The circuit breaker includes a permanent magnetic actuator and a synchronous shaft. An auxiliary contact is arranged on the synchronous shaft. The intelligent controller includes a control chip, a storage capacitor bank, and a power supply module. The control chip is used for receiving an external opening / closing instruction. The storage capacitor bank is used for controlling the action of the permanent magnetic actuator. The fast switching device includes a circuit breaker on-off state acquisition module, a voltage acquisition module, a current acquisition module, a microcontroller, and a communication module. The circuit breaker on-off state acquisition module is used for acquiring the on-off state of the circuit breaker. The voltage acquisition module and the current acquisition module are used for acquiring the voltage and current values of a line respectively.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to an uninterrupted power regulation device, system and control method. Background technique [0002] With the development of the national power system, the power grid is growing day by day, and a large number of relay protection, automatic devices, circuit breakers and other equipment are installed in the power grid, and the power supply network becomes complicated. [0003] As the power grid becomes larger and more equipment is added, the probability of grid failure is also higher, and power supply interruptions are prone to occur, which will affect the lives of power-consuming enterprises and residents. Since my country's power supply system pays attention to ensuring the stability of the power grid, the adaptive A dual power supply system has been developed. [0004] However, in the power grid powered by dual power sources at present, operation interruption (inter...
