Abstract
The utility model discloses an automatic box -type substation of defrosting, the power distribution box comprises a box body, the box upper end is provided with waterproof canopy, the box front end still is provided with the cabinet door, be provided with the sealing layer between cabinet door and the box, inboard still even cover of cabinet door has the insulating layer, be provided with automatic defrost circuit on the insulating layer, automatic defrost circuit includes power supply, heating tube, relay and electric contact thermometer, power supply, electric contact thermometer and relay be electrical connection in proper order, the relay is used for opening or breaking off the heating tube. The utility model discloses a setting up defrost circuit and sealing layer, having improved the leakproofness of the cabinet body greatly, frost resistant's ability also obviously improves simultaneously, has realized the frost -proof function of automatic defrosting.
Description
Technical field
This utility model relates to the box-type substation of a kind of automatic defrosting.
Background technology
The box-type substation of outdoor is mounted directly out of doors, stands rainwater sky or freezing weather throughout the year, and this is accomplished by improving its waterproof antifreeze ability, and the outdoor power distributing cabinet of prior art lacks waterproof ability just, lacks the most antifreeze ability especially.
Utility model content
Solve the technical problem that
The purpose of this utility model seeks to overcome disadvantages mentioned above, it is desirable to provide the box-type substation of a kind of automatic defrosting.
Technical scheme
For reaching above-mentioned purpose, the box-type substation of automatic defrosting of the present utility model, including casing, described casing upper end is provided with anti-fluid barrier；Described casing front end is additionally provided with cabinet door, is provided with sealant between described cabinet door and casing；Go back uniform fold inside described cabinet door and have thermal insulation layer；Automatic defrosting circuit it is provided with on described thermal insulation layer；Described automatic defrosting circuit includes power supply, heat-generating pipe, relay and electric contact thermometer；Described power supply, electric contact thermometer and relay are electrically connected successively, and described relay is used for opening or disconnecting heat-generating pipe.
Further, described heat-generating pipe is arranged in cabinet wall.
Further, described thermal insulation layer is that thermal insulation tile or heat insulation foam cover and form.
Further, described cabinet door is additionally provided with observation window；Described anti-fluid barrier is trapezoidal.
Further, described box bottom parcel rubber layer.
Beneficial effect
Compared with prior art, the technical solution of the utility model has the advantage that by arranging defrosting circuit and sealant, and substantially increasing the sealing of cabinet, the ability of frost resistance also significantly improves simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the box-type substation of automatic defrosting of the present utility model；
Fig. 2 is the cabinet door structure schematic diagram of the box-type substation of automatic defrosting of the present utility model；
Fig. 3 is the automatic defrosting circuit theory diagrams of the box-type substation of automatic defrosting of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
As it is shown in figure 1, the box-type substation of automatic defrosting of the present utility model, including casing 1, described casing 1 upper end is provided with anti-fluid barrier 2；Described casing 1 front end is additionally provided with cabinet door 3, is provided with sealant 4 between described cabinet door 3 and casing 1；Go back uniform fold inside described cabinet door 3 and have thermal insulation layer 6；It is provided with automatic defrosting circuit on described thermal insulation layer 6；Described automatic defrosting circuit includes power supply, heat-generating pipe, relay and electric contact thermometer；As it is shown on figure 3, described power supply, electric contact thermometer and relay are electrically connected successively, described relay is used for opening or disconnecting heat-generating pipe.
Described heat-generating pipe is arranged in casing 1 inwall, for heating inwall.
Described thermal insulation layer 6 covers for thermal insulation tile or heat insulation foam and forms.
As in figure 2 it is shown, described cabinet door 3 is additionally provided with observation window 5；Described anti-fluid barrier 2 is trapezoidal, and rainwater can be discharged along trapezoidal extension.
Wrap up rubber layer 7 bottom described casing 1, there is corrosion-resisting function, be not corroded bottom protection casing 1.
Electric contact thermometer detects when in-cabinet temperature has arrived conducting temperature, power supply, electric contact thermometer and relay form loop, thus relay is by the switch adhesive of heat-generating pipe, heat-generating pipe starts the work that defrosts, otherwise, when at a temperature of drop to turn on below temperature, the loop of power supply, electric contact thermometer and relay disconnects, relay switching off heat-generating pipe, heat-generating pipe does not works.
This utility model, by arranging defrosting circuit and sealant, substantially increases the sealing of cabinet, and the ability of frost resistance also significantly improves simultaneously, it is achieved that the function that automatic defrosting is antifreeze.
In sum, above-mentioned embodiment is not restricted embodiment of the present utility model, and modification that all those skilled in the art are carried out on the basis of flesh and blood of the present utility model or equivalent deformation, all at technology category of the present utility model.
