Description
Technical field
The invention belongs to electrical equipment technical fields, particularly dustproof and anti-explosion distribution box.
Background technology
Distribution box is that switchgear, measuring instrumentss, protection electric appliance and ancillary equipment are assembled in envelope by electrical wiring requirement
Close or semiclosed metal safe in or screen width on, form low-tension distribution box；It can be connected during normal operation by manual or automatic switch
Or disjunction circuit；By protection electric appliance cut-out circuit or alarm when failure or irregular operating；Operation can be shown by means of measuring instrumentss
In various parameters, some electric parameters can be also adjusted, to deviate normal operating conditions prompted or sent signal.
Distribution box can reasonably distribute electric energy, and the convenient switching action to circuit has higher class of safety protection, can intuitively show
Show the conducting state of circuit.
Explosion-proof electrical distribution box is often being mixed with explosive gas or the in air larger production of combustible dust concentration
It is used in place, and explosion-proof electrical distribution box will inevitably generate electric spark during the work time.Existing explosion-proof electrical distribution box
It usually seals, but if the meeting that explosion-proof electrical distribution box makes sealing causes its heat dissipation performance bad, causes in distribution box
The electric elements service life has a greatly reduced quality, the band valency higher paid required for heat dissipation.Combustible dust concentration is larger in air
Distribution box used in can prevent from exploding in a manner that adsorbing powder dust is removed completely, so can effectively reduce
Radiate cost.
Existing explosion-proof electrical distribution box is normally only equipped with warning mark simultaneously, can when needing to operate in distribution box or repair
Directly to open distribution box, and circuit is also can turn on when babinet is opened, this cause external fiery gas know from experience directly with
Distribution box contacts, and explosion accident occurs, therefore security is very low.
