Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a leakage alarm type power distribution cabinet. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the terminal equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits. It is widely used in various power stations, distribution stations, substations, industrial and mining enterprises, construction sites, etc. Among them, the leakage alarm type distribution cabinet is usually equipped with a leakage sensor and an audible and visual alarm, which can give warnings through vision and hearing. According to actual use requirements, some distribution cabinets need to be installed in outdoor natural environments. During the use of the existing leakage alarm type distribution cabinet, the audible and visual alarm outside the distribution cabinet is always in an exposed state for a long time, which makes the audible and visual alarm prone to abnormal damage, shortening the service life of the audible and visual alarm outside the distribution cabinet, and affecting the reliability of the leakage alarm function of the distribution cabinet. Therefore, we propose a leakage alarm type distribution cabinet. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model utilizes the contact between the relative end faces of the assembly seat and the sealing cover so that the sound and light alarm is in the protective space formed by the assembly seat and the sealing cover. If the leakage sensor detects that a leakage condition occurs, the controller controls the sound and light alarm and the motor to make corresponding operations according to the monitoring information of the leakage sensor. The motor drives the screw to rotate forward, and utilizes the transmission sleeve to drive the inverted L-shaped frame and the sealing cover to rise until the sealing cover is separated from the sound and light alarm on the assembly seat. The sound and light alarm sends out sound and light warning signals for visual and auditory warnings to remind professionals to carry out timely emergency repairs and maintenance. Under the condition of ensuring the warning operation effect of the sound and light alarm, a good protective effect can be played on the sound and light alarm when no warning is made, so as to avoid the sound and light alarm outside the distribution cabinet being in a naked state for a long time, and prevent the sound and light alarm from being easily damaged. This is beneficial to prolonging the service life of the sound and light alarm outside the distribution cabinet and improving the reliability of the leakage alarm function of the distribution cabinet.
