Specific embodiment

Below in conjunction with the accompanying drawings this utility model is described in further detail.

Referring to Fig. 1, this utility model entirety is by container body, control assembly 7, power Insulating frame 6 and cooling system Composition.Wherein container body is divided into control cabinet 1 and power cabin 2.Three 35kv specifications of installation set through walls on the back wall of power cabin 2 Pipe 5, corresponding with three-phase converter module respectively, the outside termination of whole machine rear wall bushing 5 in place uses steel-cored aluminium strand and reactor Connect, internal heads are overlapped with power cell using steel-cored aluminium strand, complete power and connect.

Referring to Fig. 2, control assembly 7, control framework 14 are installed in this device control cabinet 1 and control cabinet door 8, wherein controller chassis Frame 14 borrows side wall and the shifting board welded and installed plate composition of container itself, and control assembly 7, control cabinet door 8 can individually be torn open Unload and install, so since can meet production division individually get ready the goods control assembly 7, control cabinet door 8 material.Control assembly 7, control After the completion of cabinet door 8 material is individually got ready the goods, it is assembled on control framework 14 as independent material, thus improving final assembly efficiency.

Referring to Fig. 3,4, this utility model power Insulating frame 6 top is by top insulation section bar 9 traverse and container top Lid is fixed, and bottom is placed vertically by bottom insulation section bar 10 and is fixed with base plate, and the left and right sides is not fixed, and only passes through side Insulating sheet material 11 completes to climb the requirement of electricity and air channel sealing, and wherein top insulation section bar 9 is fixed by way of traverse, compared to The mode of placing vertically increases the intensity needed for power Insulating frame 6 swings, and the side insulating sheet material 11 of both sides is through machine plus milling The modes such as groove increase its overall creep age distance, and this design compared to saving Material Cost using insulation section bar and is easy to peace Dress, reduces the demand to space compared to common insulating sheet material, saves the entire length of container.

Referring to Fig. 5,6,7, the whole machine of this utility model adopts lower air inlet mode, by the anterior base plate of power cell according to air quantity Demand lays the dismountable air intake assembly 3 that polylith can be changed in internal container, and its bearing-type air intake framework 12 can Load-bearing, detachably periodically carries out changing the air intake air filter 13 in air intake assembly simultaneously；Side wall at power cell rear portion Upper installation rotates Fan casing 4, will rotate Fan casing 4 and screw in internal container and fix, it is to avoid container hanging in transportation During hoist cable extruding Fan casing, also reduce simultaneously in transportation due to container entirety ultra-wide caused by scratch wind Danger；Container arrive at scene in place after will rotate Fan casing 4 and pass through hinge and rotate to outside container and fixation；Fan casing and wind The nearly 100kg of machine overall weight, if larger by onsite moving installation difficulty, labor intensive is more, and this utility model passes through to rotation Turn Fan casing 4 to fix using hinge format, substantially reduce in-site installation difficulty and workload.

This utility model can reduce small product size, reduces on-site installation work amount, is easy to transport safely and dust-proof effect More preferably.
