Problems solved by technology

[0003] Circuit overload will cause damage to electrical components. If a protective circuit breaker is installed, the circuit breaker will trip. However, the overload circuit breaker protection of the existing circuit often occurs instantaneously, and it often disconnects the entire circuit. This sudden Power failure will often cause certain damage to some equipment, and if some important data is not saved in time during editing, it is very likely to cause data loss and cause more serious losses

Abstract

The invention discloses a circuit overload monitoring device capable of realizing selective disconnection. The circuit overload monitoring device comprises a box body, wherein a working cavity is formed in the box body, two fixing plates are fixedly arranged on the inner walls of the front side and the rear side of the working cavity in an up-down symmetrical mode. According to the invention, operating circuits are divided into white-list circuits and non-white-list circuits; when a main circuit undergoes overload, the non-white-list circuits are preferentially disconnected to relieve the overload state of the main circuit, and meanwhile, the load of the white-list circuits is guaranteed to be kept in a normal working state to prevent accidental loss caused by sudden disconnection of the main circuit; and in the process, the device gives an alarm to remind a worker to manually close some non-white-list loads, so maximum load use is realized within the load bearing range of the main circuit; and the device monitors the load condition of the main circuit in real time, can effectively realize the priority distribution of circuit energy and improves the rationality of power utilization.

Description

technical field [0001] The invention relates to the field of power grid monitoring, in particular to a circuit overload monitoring device for selective disconnection. Background technique [0002] When the current flows in the wire, it will heat the wire and increase the temperature. In electrical circuits, the amount of current that is allowed to pass continuously without overheating the wire is called the safe current carrying capacity. If the current flowing through the wire exceeds the safe current carrying capacity, it is called a wire overload. [0003] Circuit overload will cause damage to electrical components. If a protective circuit breaker is installed, the circuit breaker will trip. However, the overload circuit breaker protection of the existing circuit often occurs instantaneously, and it often disconnects the entire circuit. This sudden Power failure will often cause certain damage to some equipment, and if some important data is not saved in time during edit...
