AI Technical Summary

Problems solved by technology

There is no need to bring the actual switch transmission during the test, and the state of the switch depends on the internal software simulation of the device. This method essentially uses the software of the quick-cut device to verify the device itself, and it cannot truly verify the reliability of the quick-cut device, nor can it verify The important outer circuit of the quick cutting device

Abstract

The invention discloses a quick-cut experiment simulation switch device with adjustable tripping and closing time. The switching device includes: a bottom plate, a working switch closing button, a working switch closing time relay, a working switch tripping button, a working switch tripping time relay, Feedback terminal block, small knife switch, working switch double position relay, backup switch double position relay, command terminal block, backup switch close button, backup switch closing time relay, backup switch trip button, backup switch trip time relay, all components Connect as needed. The invention can ensure the continuous power supply of electricity customers, and solves the problem that the electricity customers need to arrange power outages for inspection and maintenance of the quick-cutting device.

Description

technical field [0001] The invention relates to the field of electric power technology, and more specifically relates to a quick-cut experiment simulation switch device with adjustable jump-off time. Background technique [0002] For important power users, such as hospitals, coal mines, power plants, electrolytic aluminum plants, etc., continuous and reliable power supply is required. In order to ensure reliable power supply for these users, at least two different power supplies are usually set up for power supply. One power supply is used as a working power supply to provide power under normal conditions, and the other is used as a backup power supply, and its backup incoming line switchgear, and the line runs without load and charged. Once the working power supply fails, the quick switch device will automatically jump off the working power incoming switch and automatically close the backup power incoming switch to ensure continuous power supply for important power users. ...
