Example 1
Referring to fig. 1 to 8, the present embodiment provides an epoxy resin fluidized insulated bus duct, including,
the conductive assembly 100 comprises a plurality of conductors 101 arranged side by side, wherein the outer side of the middle part of each conductor 101 is coated with an insulating layer, and the end part of each conductor is exposed;
the shell 200 comprises a protective shell 201 and a cover plate 202, wherein an accommodating cavity 203 is formed in the protective shell 201, the conductive assembly 100 is arranged in the accommodating cavity 203, the cover plate 202 is blocked on the accommodating cavity 203, and the cover plate 202 is connected with the protective shell 201 through a bolt 204;
the fixing component 300, the conductive component 100 is fixed in the accommodating cavity 203 through the fixing component 300.
The bus duct is a closed metal device formed from copper and aluminium bus posts, and is used for distributing large power for every element of dispersion system. Wire and cable have been increasingly replaced in indoor low voltage power transmission mains engineering projects.
The materials and the manufacture of the protective shell 201, the cover plate 202 and the conductors 101 are the same as those of the prior art, and the invention is different from the prior art in that the distance between the conductors 101 can be adjusted through the fixing assembly 300, so that the bus duct can be used as a medium-high voltage bus, when the ordinary bus duct is used in a low-voltage environment, the distance between the conductors 101 coated with the epoxy resin insulating layer can be very small or even contacted, and a certain distance is usually required to be kept between the conductors 101 in the medium-high voltage environment, so that the low-voltage bus duct can not be used as the medium-high voltage bus duct for practical use, namely, the distance between the conductors 101 is adaptively adjusted through the arrangement of the fixing assembly 300.
Specifically, the conductive element 100 is disposed on the fixing element 300, and the fixing element 300 not only clamps and fixes the conductive element 100, but also adjusts the distance between the conductors 101.
The fixed component 300 comprises a general disc 301, side controls 302 and a middle control 303, wherein the side controls 302 are fixedly arranged at two ends of the general disc 301, and the middle control 303 is arranged in the middle of the side controls 302.
The side control 302 includes a fixed plate 302a, a moving plate 302b, and an air bag 302c, the fixed plate 302a is fixedly disposed at an end of the main tray 301, the moving plate 302b is disposed inside the fixed plate 302a, and the air bag 302c is disposed between the fixed plate 302a and the moving plate 302 b.
The main plate 301 is a carrier assembly of the fixed assembly 300 and the conductive assembly 100, the side controls 302 are symmetrically disposed on two end edges of the main plate 301, the conductive assembly 100 is integrally disposed between the two side assemblies 302, and the middle control 303 is disposed between the two conductors 101.
It should be noted that the conductor assembly 100 can be three-phase three-wire, three-phase four-wire, three-phase five-wire, etc., and different application requirements of the bus duct can be changed by adaptively changing the number of the middle controls 303.
As shown in the figure, a three-phase four-wire bus duct uses three sets of intermediate controls 303 on the corresponding stationary assembly 300.
The side controls 302 are symmetrically disposed on one side of the main tray 301, it should be noted that the fixed plate 302a is always disposed on the outer side, the moving plate 302b is disposed on the inner side, and the air bag 302c is disposed between the fixed plate 302a and the moving plate 302 b;

The fixed plate 302a and the moving plate 302b are both thin hard insulating plates, heat dissipation holes are formed in the thin hard insulating plates, the fixed plate 302a and the moving plate 302b are arranged to shape and position the air bag 302c, specifically, the fixed plate 302a fixed on two sides is used for positioning as a reference, the moving plate 302b is mainly used for shaping the air bag 302c, the moving plate 302b is fixedly arranged on two sides of the air bag because the air bag is not expanded in a fixed direction, and the moving plates 302b on two sides are displaced by expansion of the air bag 302c, so that a certain distance is kept between the conductors 101.
The moving plate 302b is disposed on both sides of the air bag 302c, firstly to avoid the air bag 302c directly contacting with the conductor 101 and affecting its heat dissipation, and secondly to convert the irregular and non-directional expansion of the air bag 302c into the directional linear motion of the moving plate 302b for easy control.
The present invention adjusts the distance control between the conductors 101 by controlling the degree of inflation of each balloon.
Specifically, if the distance between the conductors 101 is reduced as much as possible, only the air bags 302c in the two side controls 302 are inflated, and the air bags in the middle control 303 are pressed to exhaust the air.
To increase the distance between the conductors 101, the air bladder in the middle control 303 is inflated, leaving the air bladder in the side control 302 squeezed out.
If the distance between two conductors 101 is adjusted, the conductors are desirably moved to the same side, and the air bag beside the side is pressed to be deflated.
As shown in fig. 3, if it is desired to increase the distance between the two conductors between the middle control 303 (3) and the side controls 302 (5), the state of the air bag 302c in the middle control 303 (2), the side controls 302 (1), and the middle control 303 (3) is maintained, and the middle control 303 (4) is inflated, and the side controls 302 (5) are allowed to be squeezed to exhaust air.
The middle control 303 is composed of moving plates 302b arranged in pairs and an air bag 302c arranged in the middle of the two moving plates 302 b.

It should be noted that the air passage 301c is a cylindrical passage, the size of the baffle 301c-2 is enough to block the communication between the first side groove 301c-1 and the adjustment cavity 301b, and the cross-sectional size of the baffle 301c-2 is smaller than that of the first side groove 301 c-1.
This structure ensures that when the baffle 301c-2 contacts the bottom surface of the first side groove 301c-1 on the side close to the adjustment cavity 301b, the first side groove 301c-1 is separated from the adjustment cavity 301b by the baffle 301c-2, and gas exchange cannot be performed, and when the baffle 301c-2 does not contact the bottom surface of the first side groove 301c-1, the first side groove 301c-1 serves as an intermediate position to communicate the gas passage 301c with the adjustment cavity 301b, that is, the adjustment cavity 301b is communicated with the interior of the airbag 302c through the ventilation tube 302 c-1.

The cooperation of radial block 301f-3 and radial slot 301e-3 serves to fix the state of control tube 301f, specifically the deflated state.
The control tube 301f is used to adjust the state of the balloon 302c, specifically, three types, the first is an inflated state, the second is a holding state, and the third is a deflated state.
When the control tube 301f is in an inflation state, one end of the hand-held wheel 301f-4 on the control tube 301f is blocked, one end of the through groove 301f-1 is positioned in the adjusting cavity 301b, at the moment, the adjusting cavity 301b is inflated through the vent hole 301d, the blocking piece 301c-2 is pressed open by high air pressure in the air pressure adjusting cavity 301b, the reed 301c-3 is compressed and deformed, and at the moment, the air bag 302c is inflated; when the inflation is stopped, the reed 301c-3 returns to make the baffle 301c-2 return.
