[0029] Example 1

[0030] like Figure 1 , Figure 2 and Figure 3As shown, a novel switch control cabinet comprises a cabinet body 1 and a side door 101 connected to the side of the cabinet body 1, one end of the side door 101 is hinged to the cabinet body 1, and the other end is detachably connected to the cabinet body 1, the rear end of the cabinet body 1 is connected to a modular digital interface 2 and an intelligent control unit 3, the modular digital interface 2 and the intelligent control unit 3 are electrically connected, and an electrical component layout connection mechanism 4 is connected to the inner wall of the other side of the cabinet body 1;

[0031] The modular digital interface 2 is used to connect external devices of different specifications and transmit the signals of the external devices to the intelligent control unit 3; the modular digital interface 2 integrates various types of digital interfaces, which can be compatible with connecting various different devices, such as sensor signal access of other components of the transformer, specifically including cooling system monitoring and control, oil surface temperature, winding temperature, oil level, body pressure, oil chromatography, etc.

[0032] The intelligent control unit 3 is used to receive and process the signals transmitted by the modular digital interface 2, and transmit the processed signals to the control terminal; the intelligent control unit 3 includes an integrated circuit board, a chip and a variety of signal transmission interfaces, which can not only realize the drive and control of the switch itself, but also monitor the various states of the transformer in real time around the clock, predict various problems of the transformer in advance, and extend the service life of the equipment.

[0033] The front end of the cabinet 1 is connected to a control panel 102 , which is electrically connected to the intelligent control unit 3 . The lower end of the cabinet 1 is connected to a plurality of wire threading tubes 103 .

[0034] The electrical component layout connection mechanism 4 is used for layout connection of internal electrical components.

[0035] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the electrical component layout connection mechanism 4 includes a first track plate 401, a plurality of second track plates 404 slidably connected to the first track plate 401, and a plurality of electrical component connectors 405 symmetrically connected to the second track plate 404. The plurality of second track plates 404 and the first track plate 401 are positioned and connected by positioning screws 403.

[0036] A sliding inner chamber 4010 is provided inside the first track plate 401, a first sliding groove 4011 is provided on an inner wall on one side of the sliding inner chamber 4010, a plurality of positioning screw holes 4013 matching with the positioning screws 403 are provided on an inner wall on the other side, and a second sliding groove 4012 is provided on the inner wall at the rear end of the sliding inner chamber 4010, and the width of the second sliding groove 4012 is the same as the thickness of the second track plate 404.

[0037] A plurality of inner sliders 402 are arranged in the sliding inner chamber 4010, the width of the second slide groove 4012 is smaller than the length of the inner slider 402, one end of a plurality of second track plates 404 passes through the second slide groove 4012, extends into the sliding inner chamber 4010 and is connected to the corresponding inner slider 402, and a positioning through hole 4020 is arranged on the inner slider 402, and the positioning through hole 4020 is matched with the positioning screw 403. When adjusting the distance between the plurality of second track plates 404, the corresponding connecting screws can be screwed out, and at this time, the inner slider 402 and the first track plate 401 are no longer limited, and the position of the second track plate 404 can be conveniently adjusted. After the adjustment is completed, the connecting screws can be screwed into the connecting screw holes 4053 again to conveniently limit the position.

[0038] A plurality of L-shaped sliding chambers 4040 are symmetrically arranged inside the second track plate 404, and third slide grooves 4041 are provided on the upper and lower end walls of the second track plate 404, the third slide grooves 4041 are communicated with the corresponding L-shaped sliding chambers 4040, and the electrical device connector 405 is located in the L-shaped sliding chambers 4040 and the third slide grooves 4041. The electrical device connector 405 can move forward, backward, left, and right along the second track plate 404.

[0039] The electrical device connector 405 includes an L-shaped sliding plate 4050 disposed in the L-shaped sliding chamber 4040, a friction layer 4051 connected to one end of the L-shaped sliding plate 4050, and a connecting plate 4052 connected to a right-angle outer wall of the L-shaped sliding plate 4050 near the friction layer 4051, and a connecting screw hole 4053 is provided on the connecting plate 4052; a gap is provided between the other right-angle outer wall of the L-shaped sliding plate 4050 and the inner wall of the L-shaped sliding chamber 4040, and the thickness of the connecting plate 4052 is less than the width of the third sliding groove 4041.

[0040] The L-shaped sliding plate 4050 can move in two directions in the L-shaped sliding chamber 4040. One is to slide forward and backward along the L-shaped sliding chamber 4040, and the other is to move left and right in a small range in the L-shaped sliding chamber 4040. The moving distance range is the size of the gap. When connecting electrical components, the electrical components and the connecting plate 4052 are connected by connecting bolts. Before connection, the position of the electrical component connector 405 is adjusted first. After adjustment, the connecting screw is passed through the electrical component and the connecting screw hole 4053 in turn and then connected with the nut. As the connecting screw and the nut cooperate, the connecting plate 4052 will be driven to move in the third slide groove 4041 in the direction close to the electrical component until the friction layer 4051 contacts the inner wall of the L-shaped sliding chamber 4040. At this time, the friction force is greatly increased, which can play a role in positioning the electrical component connector 405, thereby achieving the effect of stable installation of the electrical component. When movement or adjustment is required, just loosen the connecting bolt.

Various data are transmitted to the control terminal through optical fiber cables and network protocols, which greatly reduces the amount of wiring required for the traditional copper cable connection method. At the same time, since the new switch control cabinet integrates the functions of other control cabinets of the transformer, it can save unnecessary control cabinets accordingly, simplify the transformer design, save basic space, and ultimately reduce costs.
