Power distribution cabinet
Technical field
The present invention relates to a kind of electrical equipment, more specifically, it relates to a kind of space availability ratio is high, heat dispersion
Good, moisture resistance is good, and keeps in repair very easily power distribution cabinet in dark surrounds.
Background technology
Power distribution cabinet can also be referred to as distribution box, and from conversational implication, power distribution cabinet is exactly to be integrated with for electric energy distribution
Electrical equipment cabinet.Power distribution cabinet mainly have of both effect: one is that electrical equipment is carried out with distribution and control, two be
When overload, short circuit and electric leakage in circuit, provide power-off protection, when circuit breaks down, beneficial to control fault coverage also side
Just rapidly find out trouble point to be excluded in time, without large-area power-cuts.In addition, convenient in power distribution cabinet place various protection equipments
As prevented the fuse (electric fuse) of short circuit, prevent air switch of overload etc., protection can be played to circuit and electrical equipment
Effect.That is thing is focused on one piece, maintain easily, check.Power distribution cabinet in general, more typically in working shop of enterprise,
Workshop, such as light distribution box, power distributing cabinet etc..
At present, existing power distribution cabinet, its size generally is fixing, and internal drawer unit mostly producer is customized, therefore in cloth
When putting circuit, space size is generally moderate.But increasing with electrical equipment, often may require that the extra electrical equipment increasing in power distribution cabinet unit
Part, its size has certain difference, and during installation, the space in power distribution cabinet is not enough sometimes, and this results in and uses very not
Convenient, if purchase power distribution cabinet from newly, can seem waste again.
In addition, power distribution cabinet is when using, because internal wiring is a lot, therefore its heat dispersion requirement is higher, and if joining
Electric cabinet is chronically at the environment of dim humidity, and the aging of its internal wiring is had a significant impact, and keeps in repair, changes and also need to during circuit
Extra lighting apparatus is providing light, very inconvenient.
Content of the invention
In view of the shortcomings of the prior art, present invention is primarily targeted at providing a kind of space availability ratio high distribution
Cabinet.
The secondary objective of the present invention is to provide a kind of perfect heat-dissipating, moisture resistance good power distribution cabinet.
For realizing above-mentioned main purpose, the present invention adopts the following technical scheme that a kind of power distribution cabinet, including cabinet, described cabinet

Specific embodiment
Referring to figs. 1 to Fig. 4, power distribution cabinet embodiment of the present invention is described further.
A kind of power distribution cabinet, including cabinet 1, is provided with some drawer units 2, each drawer unit 2 is by a left side in cabinet 1
Unit and right unit are constituted, and left unit is made up of left plate 3, front apron 61, front arm-tie 71 and upper plate 51, right unit by
Right plate 4, backboard 62, rear arm-tie 72 and lower shoe 52 are constituted.Upper plate 51 and lower shoe 52 constitute base plate group 5, front draw
Plate 71 and rear arm-tie 72 constitute arm-tie group 7, and front apron 61 and backboard 62 constitute baffle group 6.The two ends of left plate 3 respectively with front
One end of baffle plate 61, one end of front arm-tie 71 are fixedly connected, and the two ends of right plate 4 then respectively with the other end of backboard 62,
The other end of arm-tie 72 is fixedly connected afterwards.The two ends of upper plate 51 are fixedly connected with the bottom of front apron 61, front arm-tie 71 respectively,
The two ends of lower shoe 52 are fixedly connected with the bottom of backboard 62, rear arm-tie 72 respectively, and upper plate 51 and lower shoe 52 are slidings
Connect, upper plate 51 and lower shoe 52 mutually slide when staggering, upper plate 51 can drive front apron 61, left plate 3 and
Arm-tie 72 moves afterwards, and lower shoe 52 then drives backboard 62, right plate 4 and front arm-tie 71 to move.So when drawer unit 2
When the electric elements of middle arrangement, circuit are excessively compact, left plate 3 and right plate 4 can be separated from each other to suitable distance, with full
The use space of sufficient drawer unit 2;And when the electric elements arranged in drawer unit 2, circuit are excessive at equal intervals, can be by a left side
Side plate 3 and right plate 4 are suitably mutually polymerized, to improve the space availability ratio of drawer unit 2;And this kind of drawer unit 2 is big
Little adjustable, therefore its exchange performance is strong.
In view of upper plate 51 with lower shoe 52 after mutual slip is staggered, easily skid, very unstable, therefore in upper plate
The lower surface of 51 upper surface and lower shoe 52 all arranges ratchet bar 53, and ratchet bar 53 can interlock against, and thus can prevent
The only skidding of upper plate 51 and lower shoe 52.
In addition, front apron 61 and backboard 62 and front arm-tie 71 and rear arm-tie 72 are arranged to step-like, in step
Two blind holes 63 of each setting in place, each setting one limit spring 64 in each blind hole 63, solid respectively for the two ends of limit spring 64
It is scheduled on the diapire of the blind hole 63 on front apron 61 and backboard 62, so when upper plate 51 and lower shoe 52 mutually slide, both
Upper plate 51 and lower shoe 52 can be prevented to be mutually disengaged, simultaneously when the step of front apron 61 and backboard 62 is when contacting, spacing
Spring 64 can be retracted in blind hole 63 impact so that front apron 61 and backboard 62 unrestricted position spring 64 when contacting.
Additionally, respectively arranging a pulley 8 in four corners of the bottom of cabinet 1, removing of power distribution cabinet so can also be facilitated
Fortune;And several bar holes 11 then can be opened up on the side wall of cabinet 1, so ensure that the thermal diffusivity within cabinet 1 is good
Good;It is correspondingly arranged a dash blade 13 above each bar hole 11, then paste last layer waterproof in bar hole 11 saturating
Air film 14, so can effectively strengthen the ability of keeping off the rain of cabinet 1, and the presence of waterproof ventilated membrane 14 not only can make steam be difficult to
Penetrate in cabinet 1 through bar hole 11, but also do not affect the exchange of air within cabinet 1 and extraneous air, do not affect
The thermal diffusivity of cabinet 1.
Certainly, because when night, when circuit in power distribution cabinet or electric elements go wrong, staff needs to use
Extra ligthing paraphernalia overhauls to inside cabinet 1, very inconvenient, so setting one is by bulb 91, interior in cabinet 1
Put power supply 92 and travel switch 93 auxiliary lighting apparatus 9 in series.One storage tank 12 is arranged on the side wall of cabinet 1, interior
Put power supply 92 and just leave in inside storage tank 12, bulb 91 is integrally fixed at the top of cabinet 1, the push rod 931 of travel switch 93
It is inconsistent through storage tank 12 and cabinet door.When cabinet door 10 is closed, cabinet door 10 props up the push rod of travel switch 93
931 so that the movable contact 933 of travel switch 93 and stationary contact 934 are in released state, and now auxiliary lighting apparatus 9 is in one
Individual off state, bulb 91 does not work, and the spring 932 on push rod 931 is in compressive state;When cabinet door 10 is opened,
Push rod 931 loses the active force that compresses of cabinet door 10, and spring 932 under compressive forces, promotes push rod 931 so that stroke is opened
Close 93 movable contact 933 and stationary contact 934 closes, now auxiliary lighting apparatus is in the state of a closed-loop path, bulb 91
It is luminous, provide illumination for maintainer, easily.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned enforcement
Example, all technical schemes belonging under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
Those of ordinary skill for, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications
Should be regarded as protection scope of the present invention.
