Short-circuit prevention control method, device and module for high-voltage perimeter precaution power grid

Abstract

The invention discloses a short-circuit prevention control method for the high-voltage perimeter precaution power grid. The short-circuit prevention control method is characterized in that a short-circuit prevention control device is serially connected to a high-voltage output loop of the high-voltage perimeter precaution power grid, detects load current of various high-voltage wires to switch and judge, and controls correspondingly. When load current of one of the high-voltage wires is out of limit, high-voltage output of the high-voltage wire is cut off. When load current of all the high-voltage wires is out of limit, high-voltage output of the high-voltage wires is cut of at intervals in turns, and one channel of high-voltage output is always kept. The invention further provides short-circuit prevention control device and module for the high-voltage perimeter precaution power grid. By the aid of the short-circuit prevention control method, device and module, impact effectiveness of the high-voltage power grid can be maintained to the greater extent, and burning down of transformers of high-voltage compartments due to long-time short circuit can be avoided.

Description

technical field [0001] The invention relates to a high-voltage power grid anti-short-circuit control technology, in particular to a perimeter protection high-voltage power grid anti-short circuit control method, a perimeter protection high-voltage power grid anti-short circuit control device and an anti-short circuit control module for the device. Background technique [0002] The focus of safety precautions in prisons and various important places is the perimeter defense facilities. The only perimeter defense facilities that have a striking effect and deterrent power are the perimeter high-voltage power grid equipment, which is the last line of defense for prisons. If the high-voltage power grid equipment cannot achieve all-weather effective strikes and accident warnings, the consequences will be disastrous. The high-voltage power grid is generally fixed on the wall or the ground at different angles. The number of high-voltage lines is 4-12 lines distributed at intervals of...

Problems solved by technology

[0003] After analysis, the perimeter protection high-voltage power grid equipment currently used in prisons uses common high-voltage transformer boosting technology, without short-circuit protection transformers and intelligent high-voltage output switching functions. On the Internet, the high-voltage network voltage short circuit will lose the electric shock ability, and the long-term short circuit will also burn the transformer of the high-voltage box
