Problems solved by technology

However, in the power distribution system with large capacity or above 10kV, compared with SSTS, the other two devices have the following obvious disadvantages: First, the cost is high, the loss is large, and the maintenance is complicated. If the UPS battery system needs to meet the large capacity output Requirements require a large number of batteries to support, but the battery system needs regular maintenance and needs to be replaced after a certain period of time; second, the structure is complex and the reliability is relatively low. It is used in UPS and DVR in 10kV systems. Voltage level restrictions often require the use of multiple devices in series and parallel. However, the application of multiple series and parallel devices is often accompanied by other redundant circuit designs such as current sharing and voltage sharing, and strict requirements such as high power and identity of the drive circuit.
Thereby greatly increasing the probability of failure of the equipment itself

Abstract

The invention relates to a high-speed switch control device which comprises a crate. A connecting backboard is parallelly arranged at the rear interior of the crate; an incident and emergent panel, a control panel, a trigger panel, a thyristor panel and a power supply panel are successively arranged on the connecting backboard from left to right, and are respectively provided with and vertically connected with an incident and emergent panel, a control panel, a trigger panel, a thyristor panel and a power supply panel which are electrically connected with one another through the connecting backboard. The high-speed switch control device provided by the invention has the advantages that the structure is more compact, and the whole or part of the control device can be changed, so that the power supply reliability of electrical loads is improved greatly.

Description

[0001] Technical field: [0002] The invention relates to a control device, more particularly to a fast switch control device. [0003] Background technique: [0004] SSTS (Smart Solid State Transfer Switch) is a kind of power quality applied in the distribution network and monitors the power quality of sensitive loads in real time. When the voltage flicker, transient low, interruption, etc. It is an intelligent switching device for supplying conversion from one power supply to another. SSTS (Smart Solid State Transfer Switch) uses thyristors and fast switches operating in parallel. When the power supply is connected, the thyristor and the fast switch closing circuit are triggered synchronously, and the power supply is quickly connected by using the short conduction time of the thyristor. After the switch is completely closed, the thyristor is then turned off to realize the load current without impact. The thyristor is transferred to the switch; when the power is cut off, the...
