Description

A combined electrical fire monitoring detector device

technical field

The utility model relates to the technical field of electrical fire monitoring detectors, in particular to a combined electrical fire monitoring detector device.

Background technique

Since the low-voltage power plug-in drawer cabinet is in a closed state during normal operation, it cannot be powered off for inspection. During normal operation, the on-duty electrician cannot detect the real-time temperature status of the electrical components in the low-voltage power plug-in drawer cabinet with an infrared temperature gun tool. In addition, there are circuit breakers, contactors, relays and other electrical components in the low-voltage power plug-in drawer cabinet, as well as the line parts connecting each component. During operation, due to excessive load or poor contact of components, it is easy to cause circuit heating or electrical The damage of components, because the low-voltage power plug-in drawer cabinet is in a closed state during normal operation, cannot be checked by power off, and the damaged components cannot be replaced in time, which further expands the fault and even leads to the occurrence of electrical fires.

At present, the operation monitoring of low-voltage electrical equipment is mainly based on the daily patrol of the electrician during the on-duty period. Due to the large amount of electrical equipment in the workshop, the on-duty electrician's inspection is neglected. Once the electrical equipment fails, the on-duty electrician is too late to deal with it quickly, which can easily lead to electrical fire accidents. At the same time, it is also possible that the hidden dangers of the equipment are not discovered in time, resulting in missed inspections and missed repairs.

Although there is a protection device in the low-voltage power drawer cabinet, the short-circuit current is more than ten times the rated current. If the fault is caused by the short circuit, the fault will often expand, because many low-voltage power drawer cabinets are connected to the same power supply bus. It may cause the failure of one device to spread to other running low-voltage devices connected to the same power supply busbar. In severe cases, it will bring about the power supply failure of the entire busbar and even cause a larger area of fire.
