Description
Technical field
The present invention relates to electrical equipment technical fields, and in particular to a kind of energy-saving power distribution cabinet with anti-theft feature.
Background technology
Power distribution cabinet is the general designation of motor control center, as the final stage device of distribution system, predominantly in region
Power equipment or lighting load provide power distribution, but the power distribution cabinet of either any form is required for wanting by electrical wiring
It asks and assembles and fixes switchgear, measuring instrumentss, protection electric appliance and ancillary equipment on cabinet stent, be equipped with since it is internal
There is expensive component, and much can all install outdoors, thus the situation that the electronic component in it is stolen easily occur, such as
Fruit cannot be effectively guarded against, once stealing, can also influence normally to power while property loss is directly contributed
Order and there are security risk, while bringing inconvenience to people's production and life to may to the power load end person and
Property causes immeasurable loss.Therefore, antitheft and safeguard construction is considered as very important match always in power distribution cabinet
It puts.
However in the prior art, it is contemplated that equipment use cost, the usual mistake of mechanical part of the theft-prevention structure of power distribution cabinet
In simple, it is antitheft to carry out only to be equipped with the cabinet door with common lock core, for being familiar with the common operating personnel of unlocking program i.e.
Cabinet door can be opened and enter cabinet theft or even part common thief occur and can smoothly pass through distribution in the case where not destroying lock body
The cabinet door of cabinet enters in cabinet, there is also the stolen time it is for a long time still undiscovered the phenomenon that；In addition it is this simple in structure
Lock core is put for a long time plus single cabinet door to be also easy to corrosion occur and enabling difficulty is caused to increase or even be also possible to lock outdoors
Dead cabinet door leads to the increase of maintenance engineering amount.And with the development of intellectual technology, also have and assisted by means of internet of things equipment
It is antitheft, but this kind of equipment is typically more complicated, and need to occupy compared with Multi net voting and human resources, very not environmentally.
And the equipment such as this kind of internet theft-prevention structure and traditional camera are similar, can only also carry out assisting antitheft or in stolen hair
Auxiliary solves a case and theft personnel midway cannot be made to stop stealing behavior in retrospect behavior after life, and destruction can still generate.Cause
This, for above-mentioned technical problem, it is necessary to be improved in the mechanical part of power distribution cabinet theft-prevention structure, one kind is provided and is had directly
The power distribution cabinet of anti-theft performance solves the problems of the prior art from foundation.
