Part, it is necessary to have reliable screen shield.
In above-mentioned, clear is answered in the range of 0.8~1.2m in front of Pedestal mounted cabinet.And in Workplace, it is
Power distribution cabinet is avoided to be misused or be damaged, power distribution cabinet is arranged on more secluded corner；And sometimes can be because of other
Operation causes some article rests before power distribution cabinet, because power distribution cabinet is arranged on more secluded corner, so that for a long time
There is no personnel to find to be blocked by thing in front of power distribution cabinet.This be badly in need of by power distribution cabinet take circuit control safety measure when,
The personnel of operation power distribution cabinet can be blocked, crash time is wasted, causes unnecessary economic loss.
Utility model content
The utility model purpose is to provide the automatic detection barrier device for dynamic power distribution cabinet, solves some articles and put
Put before power distribution cabinet, in the safety measure for being badly in need of taking circuit to control by power distribution cabinet, the personnel of operation power distribution cabinet can be blocked,
Waste crash time, the problem of causing unnecessary economic loss.
The utility model is achieved through the following technical solutions：
For the automatic detection barrier device of dynamic power distribution cabinet, including support member and be sequentially connected distance measuring sensor,
Controller, communication module and receiving terminal；Wherein：
The probe of the distance measuring sensor is arranged on support member, and distance measuring sensor, and will be away from by distance of reaction of popping one's head in
Controller is sent to from information；
