Embodiment 1

[0074] Embodiment one, such as figure 1 As shown, a box-type substation includes a box door and a box body;

[0075] The box body includes: a frame composed of vertical bars, top rails, and bottom rails, as well as bottom plates, top plates, wall panels, and horizontal partitions 1-3; middle crossbar on the frame;

[0076] One of the vertical rods in the corner area is a liquid vertical rod 1-1;

[0077] The top and bottom ends of the liquid-through vertical rod are respectively connected with a liquid inlet pipeline 2 and a liquid outlet pipeline 3; the outer sides of the liquid inlet pipeline 2 and the liquid outlet pipeline 3 are connected with a cooling liquid circulation system;

[0078] It also includes: a liquid-through horizontal bar 1-2, and the liquid-through horizontal bar 1-2 includes: a first main body 1-2-1, a second main body 1- 2-2, and the first liquid pipe 1-2-3, the second liquid pipe; the liquid pipe 1-2-3 is above the second main body 1-2-2;

[0079] T...

Embodiment 2

[0099] Embodiment 2: The scheme of Embodiment 1 also has deficiencies, and its reason is that: the liquid-passing vertical bar 1-1 is a corner column of the cabinet, and the circulation speed of the cooling liquid of the horizontal partition 1-3 is relatively slow.

[0100] The scheme of embodiment two is as follows:

[0101] Such as Figure 9 As shown, the liquid vertical rod is arranged in the middle of the frame.

[0102] Four horizontal partitions 1-3 are set, and the liquid vertical rods 1-1 are arranged in the middle of the frame of the substation instead of the vertical rods at the corners; between the vertical rods at the corners are arranged

[0103] The liquid-through horizontal bar 1-2 is arranged between the liquid-through vertical bar 1-1 and the middle horizontal bar;

[0104] The horizontal partition is fixed by the middle crossbar and the liquid passage crossbar 1-2, and the design of the liquid passage crossbar 1-2 is the same as that of Embodiment 1.

[01...

Embodiment 3

[0113] Embodiment 3, in Embodiments 1 and 2, the connecting body 6-2 between the cross bars and the first main body 1-2-1 is mainly to make the cooling liquid flow from the upper space of the connecting body 6-2 between the cross bars It flows into the first passage of the first main body 1-2-1, and flows from the second passage of the first main body 1-2-1 into the lower space of the connecting body 6-2 between cross bars.

[0114] However, in the above design: the sealing between the connecting body 6-2 between the cross bars and the first main body 1-2-1 is not good.

[0115] To this end, the following improvements are made:

[0116] 1) Yes: the two sides of the lower connection plate 1-2-1-2 of the first main body can be provided with vertical plates to form a U-shaped section, and the cooling liquid is in the U-shaped groove.

[0117] 2) Yes: the upper vertical plate 6-4 and the lower vertical plate 6-5 of the connecting body 6-1 between the vertical bars are all fixed w...

Abstract

The invention discloses a cooling system of electric power equipment, an installation mode and a cooling mode thereof. The cooling system of electric power equipment includes a framework which is formed by a vertical stick, a top cross bar, a bottom cross bar, an intermediate cross bar, and also includes four horizontal separation plates (1-3), a liquid connection vertical stick (1-1), and liquidconnection cross bars (1-2), wherein the four horizontal separation plates (1-3) are distributed around the liquid connection vertical stick (1-1); the top end and the bottom end of the liquid connection vertical stick (1-1) are respectively connected with a liquid inlet pipe (2) and a liquid outlet pipe (3); the outer side of the liquid inlet pipe (2) and the outer side of the liquid outlet pipe(3) are connected with a cooling liquid circulation system; and a coiled pipe (1-3-1) which is used for circulation of the cooling liquid, a liquid inlet and a liquid outlet are arranged in each horizontal separation plate (1-3). The cooling system of electric power equipment, the installation mode and the cooling mode thereof can greatly improve the cooling effect of large electric power equipment.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a cooling system, installation method and cooling method of electric equipment. Background technique [0002] For switch cabinets, power distribution cabinets, cabinets and other equipment, how to adjust their temperature, especially how to dissipate heat, has always been a concern of scholars. At present, common ventilation and heat dissipation methods for power cabinets include: fan-ventilation and heat dissipation, semiconductor heat dissipation, and oil cooling. [0003] As a relatively new method, oil cooling has been developed rapidly in recent years. For example, 201610369820.7 discloses a solid insulated ring network cabinet with good heat dissipation, including a cabinet body and a cabinet door. The cabinet door is equipped with a cooling fan, and the inner wall of the cabinet body is provided with a serpentine cooling pipe for internally circulating cooling oil. Both...
