Problems solved by technology

When a leakage occurs, the location and detection of the leakage point is the key. The traditional location is based on the method of checking one by one, which takes a long time and is inefficient
If the leakage is mild, it will cause the unit to stop production for a certain period of time, and if it is serious, it will bring certain economic losses to the enterprise.

Embodiment

[0033] Such as figure 1 As shown, a leakage detection circuit includes a control terminal DCU, a centralized power supply, at least one leakage detection module, and at least one loop. The centralized power supply is electrically connected to each loop, and each loop is electrically connected to a leakage detection module. The control terminal The DCU is electrically connected to each leakage detection module, and the centralized power supply is electrically connected to the control terminal DCU;

[0034] The control terminal DCU is used to set the leakage information value of the leakage acquisition and leakage detection module. When the leakage threshold is triggered, the leakage occurrence information of the corresponding point of the loop is recorded. If the leakage protection has been set, the output of the leakage loop is closed. ;

[0035] The centralized power supply is used to provide power to each circuit, control terminal DCU, and each leakage detection module;

Abstract

The invention discloses an electricity leakage protection method. The method includes S1, a user sets specific triggering conditions and checks whether an electricity leakage switch is switched on or not, executing S2 if the electricity leakage switch is switched on and ending the whole electricity leakage protection process is the electricity leakage switch is switched off; S2, a control terminal DCU performs polling on an electricity leakage detection module and compares an electricity leakage information value with an electricity leakage protection threshold value set in S1; S3, when the electricity leakage protection threshold value is triggered, a loop protection process is started according to the specific triggering conditions and electricity leakage log is recorded; S4, the user performs troubleshooting on a loop having electricity leakage through checking the electricity leakage log. According to the invention, polling is performed on the electricity leakage detection model by the control terminal DCU and processing of loop electricity leakage information is carried out, and power source protection actions are executed; the user checks the electricity leakage log, so that troubleshooting for electricity leakage becomes more accurate and convenient; loss caused by electricity leakage troubleshooting is reduced; and equipment and human safety are protected.

Description

technical field [0001] The invention relates to the technical field of power control, in particular to a leakage protection method. Background technique [0002] At present, with the rapid development of the electric power industry, the safe use of electricity cannot be ignored. In daily life, accidents caused by improper use of equipment or leakage of lines occur from time to time. It has become a top priority to prevent personal electric shock caused by electric leakage and damage to power supply equipment due to ground fault. When a leakage occurs, the location and detection of the leakage point is the key. The traditional location is based on the method of checking one by one, which takes a long time and is inefficient. If the leakage is mild, it will cause the unit to stop production for a certain period of time, and if it is serious, it will bring certain economic losses to the enterprise. Contents of the invention [0003] In view of this, in order to solve the a...
