The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. . Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

The following is a detailed description of the intelligent integrated distribution box provided by the embodiment of the present invention.

As shown in Figure 4 to Figure 11, an intelligent integrated distribution box, its specific structure includes: box body 1, electric energy meter 2, incoming line switch 3, outgoing line switch 4, capacitor protection switch 5, reactive power compensation device 7. Bus system and bus adapter 41. A partition 14 is arranged inside the cabinet 1; the busbar system includes a busbar bracket 61 and A, B, and C three-phase main busbars 62 supported by the busbar bracket 61; the busbar bracket 61 is fixed on the partitionboard 14, and A, B, and C The three-phase main busbar 62 is fixed on the busbar bracket 61, and there is a gap between the main busbar 62 and the separator 14; the A, B, and C three-phase main busbars 62 are insulated from each other.

Both the incoming line switch 3 and the capacitor protection switch 5 are fuse-type isolating switches with A, B, and C three-phase hook-type conductive parts on the back; On the A, B, C three-phase main busbars 62, the electrical connection of the outgoing line part of the incoming line switch 3 is realized. The capacitor protection switch 5 is directly hung on the A, B, C three-phase main busbar 62 through the A, B, C three-phase hook-type conductive parts, so as to realize the electrical connection of the incoming line of the capacitor protection switch 5 . The outlet switch 4 is located between the incoming switch 3 and the capacitor protection switch 5, and is fixed on the busbar adapter 41; the busbar adapter 41 is provided with A, B, C three-phase copper busbars 42, and the busbar adapter Device 41 is electrically connected with the incoming line part of outlet switch 4 through A, B, C three-phase copper busbar 42; The A, B, C three-phase conductive hook 43 is hung on the A, B, C three-phase main busbar 62 , so as to realize the electrical connection of the incoming line part of the outgoing line switch 4 . The distance L between the incoming line switch 3 and the outgoing line switch 4 (the distance L between the incoming line switch 3 and the outgoing line switch 4 refers to the distance between the incoming line switch 3 and the nearest outgoing line switch 4 from the incoming line switch 3 ) 0-10mm.

Among them, each component of the intelligent integrated distribution box may include the following implementation schemes:

(1) As shown in Fig. 8, Fig. 9, Fig. 10 and Fig. 11, there can be one outlet switch 4 or multiple ones. When there are multiple outlet switches 4, these outlet switches 4 are preferably arranged side by side at the entrance Between the line switch 3 and the capacitor protection switch 5, this not only can facilitate wiring, but also can make the inside of the box body 1 neat and beautiful. In practical application, the outlet switch 4 can adopt the molded case circuit breaker without hook in the prior art; the busbar adapter 41 can adopt the busbar adapter with the conductive hook 43 in the prior art; mm thick red copper strip welded, this copper busbar 42 has better flexibility, and can provide convenience for the wiring between the busbar adapter 41 and the outlet switch 4.

(2) The box body 1 is preferably made of sheet molding materials (SheetMouldingCompounds, SMC, also known as special fiber reinforced polyester insulating material), which are cast and spliced in sheets. The integrated distribution box is an outdoor power distribution product, and the use environment is relatively complicated, which puts forward high requirements for the anti-rust and anti-corrosion capabilities of the box body 1. However, most of the existing integrated distribution boxes are made of stainless steel, which not only makes the box The body 1 is relatively heavy, which is not conducive to miniaturization, and the price of stainless steel meeting the anti-rust and anti-corrosion requirements is relatively expensive. Sheet molding material is an unsaturated polyester fiberglass composite material made of unsaturated polyester resin as binder, adding glass fiber, filler, pigment and other additives, impregnating glass fiber yarn, and covering both sides with film. . The box 1 made of sheet molding material is not only lighter than stainless steel, but also has good electrical properties, strong chemical corrosion resistance and aging resistance, good insulation, flame retardancy, light weight, high strength and toughness.

(3) The reactive power compensation device 7 preferably adopts an intelligent power capacitor, and an intelligent distribution transformer terminal for controlling the intelligent power capacitor is preferably added in the box body 1, which can improve the intelligence level of the intelligent integrated distribution box. In the prior art, the reactive power compensation device 7 in the integrated distribution box is an ordinary power capacitor, which cannot monitor the compensation situation on-line. The intelligent integrated distribution box provided uses the intelligent distribution transformer terminal to control the intelligent power capacitor.

In practical applications, the compensation circuit can be three 10KVA+20KVA co-complementary smart power capacitors, that is, there can be three smart power capacitors, and these three smart power capacitors perform power compensation for the low-voltage side of the transformer at the same time. The intelligent distribution transformer terminal can adopt the CSG-STM-2 intelligent distribution transformer terminal. This intelligent power distribution terminal integrates GPRS wireless communication, optical fiber communication, Wi-Fi and other communication methods, and has the functions of telemetry, remote signaling, remote pulse, Remote control, statistics and other functions can automatically complete the monitoring, control, data statistics and protection of distribution transformers in indoor and outdoor substations, power distribution rooms, box-type substations and other places, and can cooperate with the main station system to form distribution automation and Remote centralized meter reading system.

(4) Since the smart power capacitor has a relatively large size, there is not enough space for the smart power capacitor to be placed in any of the electrical rooms separated by the partition plate 14 in the box body 1 . For example: as shown in Figure 6, the partition 14 divides the interior of the box body 1 into the incoming line metering room a, the distribution transformer terminal room b, and the outgoing line and compensation room c. Any of the three electrical rooms None of them has enough space to place smart power capacitors. In order not to increase the volume of the intelligent integrated distribution box and ensure the miniaturization of the entire intelligent integrated distribution box, the partition between the terminal room b of the distribution transformer and the outgoing line and compensation room c is 14 A reactive power compensation device relief hole 142 can be set on the top, and the smart power capacitor can be installed on the outlet and the bottom of the box in the compensation room c, and can pass through the reactive power compensation device relief hole 142 and extend into the distribution transformer terminal room b Inside.

Specifically, since the intelligent integrated distribution box provided by the embodiment of the utility model adopts a busbar system, and the busbar system can be directly fixed on the partition 14, so the incoming line switch 3 and the capacitor protection switch 5 can be directly hung on the busbar The electrical connection is realized on the main busbar 62 of the system (among them, the A, B, and C three-phase hook-type conductive parts of the incoming line switch 3 and the capacitor protection switch 5 are both conductors and fixed parts), and the outgoing line switch 4 can be transferred through the busbar. The connector 41 is hung on the main busbar 62 of the busbar system to realize electrical connection (wherein, the A, B, and C three-phase conductive hooks 43 of the busbar adapter 41 are both conductors and fixed parts); this is different from the existing integrated power distribution Compared with the box, the installation beam 11' and bus bar 6' are omitted, so the distance L between the incoming line switch 3 and the outgoing line switch 4 can be reduced to no more than 10mm, so that the volume of the integrated distribution box can be greatly reduced Small, realizes the miniaturization of the integrated distribution box, and can reduce the manufacturing cost. In addition, the busbar system is located on the back of the incoming line switch 3, outgoing line switch 4, and capacitor protection switch 5, which is difficult to touch from the front, so this improves the electrical safety of the intelligent integrated distribution box.

In summary, the embodiment of the utility model can not only greatly reduce the volume of the integrated distribution box, realize the miniaturization of the integrated distribution box, but also improve electrical safety, prolong the service life, reduce manufacturing costs, and make it more efficient. market competitive advantage.
