Abstract
The utility mode discloses a de-icing alternating current connecting box which comprises a box body (1). A three-phase connection copper bar (2) is arranged inside the box body (1), the three-phase connection copper bar (2) is fixed on the box body (1) through an insulator (3), and more than four cable inserting holes (4) are respectively arranged at two ends of the three-phase connection copper bar (2). Three copper bars are arranged inside the box body of the de-icing alternating current connecting box, so that a de-icing circuit is connected to the copper bars directly. The three copper bars serve as carriers connecting a de-icing alternating current transformer to multiple melted ice high-voltage transmission line (triple pole). The de-icing alternating current connecting box can achieve fast connection between the de-icing circuit and a de-icing transformer source, shorten the distance of artificially connecting cable, improve the work efficiency of a de-icing circuit, reduce the number of workers and reduce labor intensity for the workers.
Description
Technical field
The utility model type relates to a kind of electrical structure, and especially a kind of ice-melt exchanges link box.
Background technology
China Nanfang Grid Co., Ltd is successfully developing 10kV interchange ice-melt transformer 2011 years, this interchange ice-melt transformer can move to the transformer station that any one has suitable ice-melt power supply easily, when needed this station ultra-high-tension power transmission line is carried out the ice-melt operation.Because this interchange ice-melt transformer is new equipment, mode in transformer station access electric power system does not have ripe technical scheme and special-purpose access device, therefore just in the urgent need to a kind of equipment as interchange ice-melt transformer with carried out being connected rapidly and efficiently between the ice-melt ultra-high-tension power transmission line (three utmost points).
Summary of the invention
The purpose of this utility model is: provide a kind of ice-melt to exchange link box, can increase work efficiency, it is low to reduce operating risk, to overcome the deficiencies in the prior art.
The utility model is achieved in that ice-melt exchanges link box, comprises casing, is provided with three copper bars that are connected in casing, and three copper bars that are connected are fixed on the casing by insulator, are equipped with the cable access hole more than 4 at three two ends that are connected copper bar.
In casing, be provided with heater.Starting heater can heat box house, avoids box house to make moist, and does not affect normal use.
In casing, be provided with illuminating lamp.In the situation such as bad or operation at night, can see by illuminating lamp the situation of box house in the daylighting condition clearly.
Owing to adopted above-mentioned technical scheme, compared with prior art, the utility model adopts three copper bars is set in casing, can directly DC ice-melting be connected on this copper bar, become and connect to exchange ice-melt transformer and many by the carrier between the ice-melt ultra-high-tension power transmission line (three utmost points), can realize being connected fast between DC ice-melting and the ice-melt transformer source, shortened the distance of artificial stube cable, can improve the operating efficiency of line ice-melting, the quantity that reduces a staff and reduce staff's labour intensity.The utility model is simple in structure, implements easily, and result of use is good.

Fig. 2 is end view of the present utility model;
Fig. 3 is the utility model installation site and connection diagram in electric power system.
Embodiment
Embodiment of the present utility model: the structure of ice-melt interchange link box as shown in Figure 1, comprise casing 1, in casing 1, be provided with three and have three of enough current capacities copper bar 2 that is connected, three copper bars 2 that are connected are fixed on the casing 1 by insulator 3, are equipped with the cable access hole 4 more than 4 at three two ends that are connected copper bar 2; In casing 1, be provided with heater 5; In casing 1, be provided with illuminating lamp 6.
In use, three ends that are connected copper bar 2 are connected with the output 7 of ice-melt transformer as hard-wired high-tension cable, the other end divides two branch roads: the 1st branch road is no more than 10 meters high-tension cable and is connected (just connect when needing ice-melt, during not ice-melt this cable untied separately and deposit) with ultra-high-tension power transmission line 8 with length; The 2nd branch road is connected with the input 9 of hard-wired high-tension cable with next ice-melt Special alternating-current link box.
