Description
Technical Field
[0001] The utility model relates to the technical field of substation equipment, in particular to an anti-electric shock substation device which is convenient for maintenance of a traction substation. Background Art
[0002] A traction substation is a place where the electric energy sent from a power plant through a power transmission line is converted into a voltage suitable for locomotives and vehicles, and then distributed to the contact network or contact rail. It is divided into a DC traction substation and an AC traction substation. The former reduces the voltage of the high-voltage AC power sent from the power transmission line through a transformer, and then converts it into DC through a rectifier before sending it to the contact network or contact rail. The latter can be divided into industrial frequency, low frequency single-phase and industrial frequency three-phase AC traction substations, which convert the electric energy sent from the power transmission line into the above three types of AC respectively, and then distribute it to the corresponding contact network. The main equipment of a traction substation includes a transformer for converting voltage, a distribution device for receiving and distributing electric energy, and a switch for control and protection.
[0003] When the substation cabinet used for traction substation is being repaired, since the equipment is installed in the cabinet, the maintenance personnel need to reach into the cabinet for maintenance. The limited space in the cabinet and the installation of substation equipment make maintenance inconvenient and there is a risk of electric shock. Therefore, there is an urgent need for a substation cabinet device that is convenient for maintenance personnel to repair. Utility Model Content

[0035] Reference Figure 1-5 As shown, the utility model provides an anti-electric shock substation device which is convenient for maintenance of a traction substation, comprising:
[0036] The transformer cabinet unit 100 includes a cabinet body 110 and a plug-in frame edge 120 fixedly welded at a cabinet opening of the cabinet body 110, and a sliding cabinet door 130 is movably plugged and installed in the plug-in frame edge 120;

[0038] The base plate member 220 is movably mounted on the guide column 210, and the guide column 210 is fixedly welded in the cabinet 110. When repairing the transformer equipment installed on the base plate member 220, the base plate member 220 is pulled out from the cabinet 110, so that the transformer equipment installed on the base plate member 220 is exposed from the cabinet opening of the cabinet 110. Compared with the traditional transformer cabinet device, during maintenance, the utility model does not require maintenance personnel to put their hands into the cabinet for maintenance, and the space is larger and will not be blocked by the cabinet wall during maintenance, which is more convenient for maintenance. At the same time, maintenance outside the cabinet greatly reduces the risk of electric shock and improves safety.
[0039] As a further preferred embodiment of the above embodiment, locking pin holes 111 are provided at both upper and lower ends of the cabinet body 110 .
[0040] As a further preferred embodiment of the above embodiment, limiting grooves 121 are provided at the upper and lower ends of the plug-in frame edge 120 .
[0041] The sliding cabinet door 130 includes a cabinet plate 131 movably plugged into the plug-in frame edge 120 and limit posts 132 fixedly welded to the upper and lower ends of the cabinet plate 131;
[0042] The limiting column 132 is movably inserted into the limiting groove 121 .
[0043] During maintenance, the sliding cabinet door 130 is pulled out from the plug-in frame edge 120, and the limiting column 132 moves in the limiting groove 121. The limiting groove 121 blocks the limiting column 132 to prevent the sliding cabinet door 130 from detaching from the plug-in frame edge 120. Compared with traditional rotating cabinet doors, the sliding cabinet door will not automatically rotate after opening, which is more convenient for maintenance.
[0044] As a further preferred embodiment of the above embodiment, a stopper 211 is welded to one end of the guide pillar 210 .
[0045] The base plate 220 includes a connecting base plate 221 and a mounting plate 222 fixedly welded on the connecting base plate 221 for mounting the transformer equipment. The guide pillars 210 are movably plugged at the four corners of the connecting base plate 221.
[0046] The diameter of the guide column 210 matches the diameter of the insertion holes at the four corners of the connecting seat plate 221, and the diameter of the stopper 211 is larger than the diameter of the insertion holes.
[0047] As a further preference of the above embodiment, the positioning lock 230 includes a U-shaped bracket seat 231 welded on the connecting seat plate 221 and a positioning column 232 fixedly welded on one end of the U-shaped bracket seat 231, and the positioning column 232 is movably provided with a pin tube 233, and the positioning column 232 is also provided with a reset spring 234, one end of the reset spring 234 is connected to the U-shaped bracket seat 231, and the other end is connected to the pin tube 233, and the other end of the pin tube 233 passes through the other end of the U-shaped bracket seat 231.
[0048] The outer diameter of the pin tube 233 matches the diameter of the locking pin hole 111 , the inner diameter of the pin tube 233 matches the diameter of the positioning column 232 , and a paddle 235 is fixedly welded to one end of the pin tube 233 connected to the return spring 234 .
[0049] When performing maintenance, the substrate member 220 is pulled out from the cabinet 110 so that the transformer equipment installed on the substrate member 220 is exposed from the cabinet opening of the cabinet 110. After the substrate member 220 is moved into place, the pin tube 233 is pushed out under the action of the reset spring 234, so that the pin tube 233 is inserted into the locking pin hole 111, thereby locking the position of the substrate member 220 and facilitating maintenance personnel to perform maintenance. In normal use, the substrate member 220 is pushed into the cabinet 110, and the pin tube 233 is inserted into the locking pin hole 111 to fix the position of the substrate member 220 and prevent the substrate member 220 from moving in the cabinet 110.
