Automatic power-off switch device for distribution box during earthquake

Abstract

The invention relates to the technical field of power distribution switches, and discloses an automatic power-off switch device for a power distribution box during an earthquake, which comprises a mounting base, a lower supporting mechanism is fixedly mounted on the mounting base, an induction mechanism is mounted on the right side of the lower supporting mechanism, a cut-off mechanism is connected to the right end of the lower supporting mechanism, and the induction mechanism is connected with the cut-off mechanism. An upper supporting mechanism is slidably mounted on the mounting base and corresponds to the lower supporting mechanism, and an electrifying mechanism is connected to the upper portion of the upper supporting mechanism. The induction mechanism can automatically drive the cut-off mechanism to work during an earthquake, so that the cut-off mechanism acts on the lower supporting mechanism, the upper supporting mechanism falls down to drive the power-on mechanism to cut off current, and automatic circuit cut-off operation during the earthquake is achieved; the distribution box is prevented from being impacted to cause work of the induction mechanism, and automatic power off caused by the fact that the distribution box cannot distinguish earthquakes and impacts is solved.

Description

technical field [0001] The invention relates to the technical field of power distribution switches, in particular to an automatic power-off switch device for power distribution boxes during earthquakes. Background technique [0002] The distribution box has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, not limited by the site, widely used, stable and reliable operation, high space utilization rate, less land occupation and environmental protection effect. It is the control center that directs various components in the power supply line to distribute electric energy reasonably, and it is the control link that reliably receives the upper-end power supply and correctly feeds out the load electric energy. [0003] The existing distribution box cannot automatically cut off the power after an earthquake. When the distribution box is located in the earthquake area, if the power is not cut off, it ...

AI Technical Summary

Problems solved by technology

[0003] The existing distribution box cannot automatically cut off the power after an earthquake. When the distribution box is located in the earthquake area, if the power is not cut off, it will easily cause injury to the people in the earthquake area. In addition, most of the existing distribution boxes are installed in Next to the road, it is impossible to distinguish between an earthquake and a slight impact from a car. When a car hits the distribution box, it may easily cause a false power outage, and some existing automatic switches are mostly electric and program-driven, easy to damage, and require irregular maintenance.
