Abstract
The invention discloses a remote dehumidification temperature-control cable distribution box. The remote dehumidification temperature-control cable distribution box comprises a cuboid box body and a rain-shielding box cover. The rain-shielding box cover is of an isosceles triangle shape, corner channel steel is arranged at the bottom of the box body, and a constant temperature control system is arranged inside the box body. The rain-shielding box cover is hollow, drying agent bags are arranged inside the rain-shielding box cover, a baffle is arranged between the rain-shielding box cover and the box body, the baffle enables the rain-shielding box cover and the box body to be attached to each other through a direct current electromagnet, and the control end of the electromagnet is connected with a single-chip microcomputer. According to the remote dehumidification temperature-control cable distribution box, the constant temperature control system arranged inside the box body ensures that the temperature inside the box body is constant all the time, so that electrical components are not prone to aging, unpredictable factors are prevented from happening, and safe operation of an electric system is guaranteed; besides, the baffle can be remotely controlled to be opened or closed, and water in damp air can be absorbed by a drying agent arranged inside the rain-shielding box cover when the baffle is opened.
Description
Technical field
The present invention relates to electrical equipment technical field, be specifically related to a kind of long-range dehumidifying temperature control cable distribution box.
Background technology
Cable distribution box (Cable Distribution Box) is that a kind of being used for implemented tap, branch, continued and the equipment of change-over circuit cable line, most for outdoor.This equipment is not long service time in China, and insider and electric power system are used department to its understanding and understood still inconsistently, particularly to drawing from the external European and American device etc. of patching, have different views.Below the correlation technique key element of cable distribution box is briefly described and is discussed, for the reference of electric power design and running department.
The type of cable distribution box
Cable distribution box is divided into two large classes by its electric formation: a class is not contain any switchgear, only has pair cable socket to process and the annex being connected in casing, relatively simple for structure, small volume, and function is more single, can be described as common distribution box; Another kind of is in case, not only to have the annex of common distribution box, also contains one or more switchgear, and its structure is comparatively complicated, and volume is larger, and interface unit is many, and manufacturing technology difficulty is large, and cost is high, can be described as senior distribution box.
1, common distribution box
In common distribution box, there is no switchgear, inlet wire and outlet link together on electric, and current potential is identical, are suitable for tap or branch connection.Ordinary practice is returned inlet wire to number and is added that outlet returns number and be called minute numbers.Three branch cable distribution boxes for example, it each goes up three equipotential connection contacts mutually, can enter one as one-in-and-two-out or two and go out.Cable distribution box includes U, V, and W three-phase, three-phase circuit structure is identical, and in-line arrangement is together.
2, senior distribution box
Senior distribution box contains switchgear, both can play tap, branch's effect of common distribution box, can play again control, the conversion of power supply circuits and change operational mode.Switch fracture is roughly divided into cable loop inlet wire side and outgoing line side, and both sides current potential can be different.Therefore switchgear itself has larger volume, and the overall dimension of senior distribution box is larger, is highly generally 1.4～1.8 m, and the degree of depth is about 0.9～1.0 m, and length is determined according to contained switchgear number, how between 1.0 m to 2.4 m.The profile of casing is similar to outdoor box transformer, has the door of several activities on case shell, and some doors are to establish for the operation of switchgear, and some doors are to establish for installation or the Maintenance and Repair of cable connector part.
Existing cable distribution box exists in defect aspect heat dispersion, temperature control, affects working effect and useful life.
Summary of the invention
