All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the prior art, because the channel steel is pre-buried to the ground, therefore, when installing the isolator cabinet, the installation bolt of fixed usefulness needs to pass cabinet body bottom, insulation board back nest to the channel steel from isolator cabinet body. Wherein, in order to realize insulating installation, the bolt insulating sleeve is sleeved outside the installation bolt.
However, since the insulation distance between the dc electrical equipment, the channel steel, and the mounting bolts in the isolation switchgear is small, when the temperature in the environment is high and the air humidity is high, the creepage distance and the insulation gap may be insufficient, and there is a creepage phenomenon, which affects the insulation performance.
In order to solve the problems, the application provides a power distribution cabinet installation system, wherein insulating plates are respectively connected with a disconnecting switch cabinet and channel steel through different bolts, so that the disconnecting switch cabinet is connected with the insulating plates through one bolt, and the insulating plates are connected with the channel steel through the other bolt. The isolating switch cabinet is connected with the insulating plate through bolts, so that the bolts penetrate through the bottom of the isolating switch cabinet body from the inside of the isolating switch cabinet and then are transmitted into the insulating plate; when the insulating plate is connected with the channel steel through the bolts, the bolts penetrate through the channel steel from the bottom of the channel steel and then are transmitted into the insulating plate, so that a direct communication channel between the isolating switch cabinet and the channel steel is disconnected, and the insulating performance is improved.
Fig. 1 is a schematic partial structure diagram of a power distribution cabinet installation system according to an embodiment of the present application, where, as shown in fig. 1, the power distribution cabinet installation system includes: the power distribution cabinet is fixedly connected with the insulating plate 100 through a first bolt 300, the first bolt 300 penetrates through the bottom cabinet body from the inside of the power distribution cabinet and then is embedded into the insulating plate 100, and the insulating plate 100 is connected with the channel steel 200 through a second bolt 400;
Wherein the second bolt 400 includes: a non-circular base 410 and a screw 420 connected to the non-circular base 410;
The channel steel 200 is provided with a first non-circular through hole 210, the non-circular base 410 is clamped in the first through hole 210, the insulating plate 100 is provided with a first groove 110 with an upward opening, the bottom of the first groove 110 is provided with a second through hole 120 matched with the screw 420, and the upper part of the screw 420 penetrates through the second through hole 120 and then is connected with the nut 500. Wherein the aperture of the second through hole 120 is smaller than the size of the first groove 110.
In this embodiment, the power distribution cabinet is illustrated by taking an isolating switch cabinet as an example:
When the isolating switch cabinet is installed, the insulating plate 100 is fixedly connected with the channel steel 200, wherein the channel steel 200 is pre-buried to the ground, and therefore, before the channel steel 200 is pre-buried, the second bolt 400 is placed at the bottom of the channel steel 200, and the second bolt 400 penetrates through the first through hole 210. The channel steel 200 is then installed on the ground.
In order to tighten the nut 500, a conventional bolt generally uses a tool such as pliers to fix the bolt and uses a tool such as pliers to rotate the nut 500. Therefore, in this embodiment, since the second bolt 400 is placed at the bottom of the channel steel 200, it passes through the channel steel 200 and is then introduced into the insulating plate 100, and the channel steel 200 is then installed on the ground after the second bolt 400 is placed, at this time, the second bolt 400 cannot be fixed by using tools such as pliers.
Thus, in the present embodiment, the non-circular base 410 is included in the second bolt 400, and at the same time, the first through hole 210 is provided on the channel steel 200, so that the non-circular base 410 can be nested in the first through hole 210. In order to avoid the rotation of the non-circular base 410 in the first through hole 210 when the nut 500 is tightened, the non-circular base 410 and the first through hole 210 are designed to be non-circular, so that the non-circular base 410 cannot rotate in the first through hole 210, and the non-circular base 410 and the first through hole 210 are engaged with each other, for example, the non-circular base 410 is pentagonal, triangular, elliptical, etc., and accordingly, the first through hole 210 is pentagonal, triangular, elliptical, etc., so that when the non-circular base 410 penetrates the first through hole 210, each side of the non-circular base 410 corresponds to each side of the first through hole 210, and resistance is generated to the non-circular base 410 by the first through hole 210, thereby preventing the non-circular base 410 from rotating. The shapes of the non-circular base 410 and the first through hole 210 are not limited, and the non-circular base 410 cannot rotate in the first through hole 210.
When the insulating plate 100 and the channel steel 200 are fixed, the second bolt 400 is placed at the bottom of the channel steel 200, the screw 420 penetrates through the first through hole 210, then, the channel steel 200 is placed in a groove chiseled out on the ground, wherein after installation, two sides of the channel steel are attached to two side walls of the groove on the ground, and the upper surface of the channel steel is flush with the ground. Then, the insulating plate 100 is placed on the channel steel 200, so that the first groove 110 and the second through hole 120 on the insulating plate 100 correspond to the first through hole 210, and the screw 420 passes through the second through hole 120 and protrudes into the first groove 110.
At this time, the position of the second bolt 400 may be adjusted such that the non-circular base 410 is snapped into the first through hole 210, and then the nut 500 is mounted on the screw 420, and the nut 500 is screwed on the screw 420 using a tool such as pliers. At this time, since the first through hole 210 plays a role of blocking the rotation of the non-circular base 410, the non-circular base 410 is not rotated when the nut 500 is tightened.
Finally, the isolating switch cabinet is placed on the insulating plate 100 and fixed through the first bolt 300, specifically, the first bolt 300 penetrates through the bottom of the cabinet body inside the isolating switch cabinet and penetrates into the insulating plate 100, so that the isolating switch cabinet and the insulating plate 100 are fixed, and the isolating switch cabinet is installed.
In this embodiment, the power distribution cabinet is fixedly connected with the insulating board 100 through the first bolt 300, and the insulating board 100 is connected with the channel steel 200 through the second bolt 400; wherein the second bolt 400 includes: the non-circular base 410 and the screw 420 that is connected with the non-circular base 410, and set up non-circular first through-hole 210 on the channel-section steel 200, non-circular base 410 joint is in first through-hole 210, has set up the ascending first recess 110 of opening on the insulation board 100, and the second through-hole 120 that matches with screw 420 is set up to the bottom of first recess 110, and the upper portion of screw 420 runs through second through-hole 120 after being connected with nut 500. The novel power distribution cabinet has the advantages that no direct connection channel exists between the power distribution cabinet and the channel steel 200, the insulation gap is increased, the creepage distance is increased, and furthermore, as no direct connection channel exists between the power distribution cabinet and the channel steel 200, the influence of dust and moisture on the power distribution cabinet installation system is reduced, and the insulation performance is improved. In addition, by designing the second bolt 400 as a structure of the profiled base, the installation of the power distribution cabinet can be achieved without changing the inherent structure of the electrical equipment, the channel steel 200, the civil engineering and the decorative layer in the power distribution cabinet.
Optionally, the height of the second bolt 400 is greater than the height of the channel steel 200, the height of the screw 420 is greater than the height of the second through hole 120, and is less than the thickness of the insulating plate 100.
Specifically, the second bolt 400 has a height greater than that of the channel steel 200, so that when the second bolt 400 is placed and the channel steel 200 is installed, the screw 420 can pass through the first through hole 210, so that the second bolt 400 can be rotated conveniently, and the insulating plate and the channel steel 200 are fixed by the second bolt 400. And, the screw 420 is designed to have a height greater than that of the second through hole 120, so that the screw 420 can be inserted into the first groove 110 through the second through hole 120 to mount the nut 500 when the insulation plate 100 and the channel steel 200 are fixed. The height of the screw 420 is also smaller than the thickness of the insulating board 100, so that the upper end of the screw 420 is located in the first groove 110, and the screw 420 is prevented from extending out of the first groove 110 to affect the installation of the isolating switch cabinet. And, the upper end of screw 420 is located first recess 110, does not contact with the isolator cabinet, avoids the phenomenon that there is direct intercommunication passageway between isolator cabinet and channel-section steel 200, has improved insulating properties.
Optionally, the non-circular base 410 includes: base body 411 and dysmorphism piece 412, dysmorphism piece 412 are installed on base body 411, and the bottom and the dysmorphism piece 412 of screw rod 420 are connected, and dysmorphism piece 412 joint is in first through-hole 210.
Specifically, the base body 411 may have a square, a cuboid, a cylinder, or a cylinder, where the cylinder is placed in a horizontal direction when the special-shaped block 412 has a cylinder structure, so that the special-shaped block 412 is prevented from rotating in the first through hole 210.
As shown in fig. 2, the base body 411 is a cuboid, the special-shaped block 412 is a three-dimensional structure with a parallelogram cross section, and correspondingly, the shape of the first through hole 210 is also a parallelogram, and when the insulating plate 100 is fixed on the channel steel 200, the special-shaped block 412 is clamped in the first through hole 210 through the action between the sides of the parallelogram of the special-shaped block 412 and the sides of the parallelogram of the first through hole 210, so that the special-shaped block 412 is prevented from rotating when the nut 500 is screwed.
Wherein, design non-circular base 410 into the structure of base body 411 and dysmorphism piece 412, and dysmorphism piece 412 installs on base body 411, because the size of base body 411 is greater than the size of first through-hole 210, consequently, can carry out spacing through base body 411 to second bolt 400, avoid the whole upward movement of second bolt 400 under the effect such as vibration that the train operation produced, upwards top insulation board 100 to influence the connection of insulation board 100 and isolator cabinet, thereby influence isolator cabinet installation's stability.
Alternatively, as shown in fig. 1, the height of the base body 411 is smaller than the difference between the height of the channel steel 200 and the thickness of the horizontal plane of the channel steel 200.

Optionally, as shown in fig. 1, the insulating board 100 is provided with a second groove 130 with a downward opening, and the second groove 130 is matched with the special-shaped block 412.
Specifically, when the second bolt 400 is produced, the thickness of the special-shaped block 412 is equal to the thickness of the channel steel 200, that is, the depth of the first through hole 210, but due to production errors, the thickness of the special-shaped block 412 may be greater than the depth of the first through hole 210, so that the special-shaped block 412 may be moved upwards under the action of train vibration or the like, and the insulating plate 100 is lifted upwards, thereby affecting the fixation of the isolating switch cabinet. Therefore, the insulating board 100 is provided with the second groove 130 with the downward opening, where the size of the second groove 130 is greater than or equal to the size of the first through hole 210, or the size of the second groove 130 is greater than or equal to the size of the special-shaped block 412, so as to accommodate the special-shaped block 412, prevent the special-shaped block 412 from moving upward, and push the insulating board 100 upward, thereby improving the installation stability of the isolating switch cabinet.

A flat pad 700 is arranged between the spring pad 600 and the bottom of the first groove 110, and the stress surface of the nut 500 is increased through the flat pad 700, so that the tightness of the nut 500 is increased, and the nut 500 is prevented from loosening.
Alternatively, as shown in fig. 3, the number of insulating plates 100 is plural, and the adjacent two insulating plates 100 are connected in a lap joint manner, wherein the sum of the thicknesses of the lap joint positions of the adjacent two insulating plates is equal to the thickness of the insulating plates at other positions except the lap joint position.
