They are easy to install and highly reliable and are mainly used in high-voltage power distribution devices, such as substations, factory distribution rooms and other places. Currently, busbar cold shrink accessories are made of shielding tubes and stress cones made of semi-conductive silicone rubber and are prepared by injecting insulating liquid silicone rubber at room temperature and curing it in a mold.

[0003] By using shielding tubes and stress cones, the electric field can be effectively dispersed, the stress caused by electric field concentration can be reduced, and the insulation performance can be improved. The insulating liquid silicone rubber has excellent electrical insulation properties and can effectively isolate the high voltage environment.

[0045] See also Figure 1 , Figure 7 , Figure 8 and Fig.10 The inflation component 423 includes a pushing tube 4231 that is slidably connected to the left end wall of the cylindrical tube 421. The left end of the pushing tube 4231 is fixedly connected to the sliding plate 433.

[0046] During specific operation, the air inlet pipe 4232 is connected to the existing air pump outside before work. Initially, the sliding plate 433 slides to the limiting opening 432 on the left side, and the limiting plate 434 is engaged with the limiting opening 432 on the left side, thereby limiting the sliding plate 433. At this time, the sliding plate 433 drives the two pushing tubes 4231 to be in a sealed position, thereby making the cylindrical tube 421 in a sealed state.

[0047] See also Figure 8 , Fig. 9 and Fig.10 A plurality of evenly distributed air outlet holes 4233 are provided on the wall of the pushing tube 4231 located inside the cylindrical tube 421, and a plurality of evenly distributed cylindrical rods 4234 are installed on the right end of the pushing tube 4231 through a connecting frame.

[0048] See also Figure 1 , Fig. 9 and Fig.10 The inflatable component 423 also includes a movable plate 4235 sleeved on the outer surface of the cylindrical rod 4234, and an inclined waist-shaped hole 4236 is opened on the movable plate 4235, and the waist-shaped hole 4236 is slidably connected to the cylindrical rod 4234.

A plurality of rectangular through holes evenly distributed in the circumference are opened on the left and right sides of the tube wall of the cylindrical tube 421, and the rectangular through holes are slidably matched with the corresponding blocking strips 4238.

[0049] During specific operation, when the sliding plate 433 slides in the direction of the limiting opening 432 located on the left side, the sliding plate 433 drives the two pushing tubes 4231 to move, and the two pushing tubes 4231 slide in the corresponding waist-shaped holes 4236 through multiple cylindrical rods 4234 to drive the corresponding moving plates 4235 to move away from the axis of the cylindrical tube 421, and the moving plate 4235 drives the two blocking strips 4238 to engage with the corresponding rectangular through holes on the wall of the cylindrical tube 421 through the connecting strip 4237, so that the cylindrical tube 421 is in a sealed state, and the end of the blocking strip 4238 away from the connecting strip 4237 is flush with the outer wall of the cylindrical tube 421.

[0050] See also Figure 1 , Figure 2 , Figure 6 , Figure 7 and Fig.11The positioning component 44 includes four guide rods 441 distributed in a rectangular shape and installed at the right end of the vertical section of the L-shaped support plate 41. A plurality of evenly distributed sliding blocks 442 are slidably connected to the four guide rods 441. A cross through hole 443 is opened in the middle of the sliding block 442. A positioning component 444 is connected in the cross through hole 443. A pushing component 445 is connected to the upper end of the sliding block 442. The positioning component 44 also includes two positioning screws 446 threadedly connected to the lower end of the sliding block 442 and symmetrically distributed front and back. A locking column 448 is symmetrically arranged front and back above the sliding block 442. A rotating plate 447 is installed at both ends of the locking column 448. The lower end of the rotating plate 447 is hinged to the sliding block 442 through a pin shaft with a torsion spring.

[0051] During specific operation, according to the installation positions of the stress cone and the shielding tube, multiple sliding blocks 442 are pushed in sequence. After the sliding block 442 drives the positioning assembly 444 to move to the desired position, the two positioning screws 446 at the lower end of the sliding block 442 are rotated, and the upper end of the positioning screw 446 is tightly attached to the corresponding guide rod 441 on the lower side, thereby realizing the function of limiting and locking the sliding block 442.

[0052] See also Figure 2 and Figure 6 The positioning assembly 444 includes two positioning rods 4441 which are symmetrically arranged front and back and slidably connected in the horizontal section of the cross hole 443. The opposite ends of the positioning rods 4441 are integrally formed with rectangular protrusions. A traction rope 4443 is installed between the two positioning rods 4441. A connecting spring 4442 is installed between the rectangular protrusion on the positioning rod 4441 and the vertical hole wall of the horizontal section of the cross hole 443.

[0053] During specific operation, initially, the connecting spring 4442 is in a normal state. At this time, the end of the positioning rod 4441 located outside the sliding block 442 is close to the outer surface of the cylindrical tube 421. When the sliding block 442 slides, the two positioning rods 4441 are driven to move along the outer surfaces of the two cylindrical tubes 421. When the positioning rod 4441 moves to the working position and limits the sliding block 442, the No. 1 stress cone, the shielding tube and the No. 2 stress cone are sequentially placed on the cylindrical tube 421 and moved to the desired position (such as Fig.12 As shown in the figure, multiple positioning rods 4441 can ensure the accuracy of the moving positions of the No. 1 stress cone, the shielding tube and the No. 2 stress cone, avoid the phenomenon of inconsistent specifications of the insulating tube formed later, and improve the forming effect of the insulating tube. When the stress cone and the shielding tube slide on the cylindrical tube 421, they push the slope on the positioning rod 4441, and the positioning rod 4441 is forced to move into the sliding block 442, thereby avoiding the positioning rod 4441 blocking the stress cone and the shielding tube.

[0054] See also Figure 1 , Figure 5 and Figure 8 The sealing assembly 424 includes a sealing sleeve 4241 which is sleeved on the right end of the cylindrical tube 421 and is in a "+" shape. A threaded column 4242 is installed at the inner end of the vertical section of the sealing sleeve 4241. The threaded column 4242 is threadedly connected to the right end of the cylindrical tube 421.

[0055] During specific operation, after the No. 1 stress cone, the shielding tube and the No. 2 stress cone are moved to the desired positions respectively, the sealing sleeve 4241 is sleeved on the right end of the cylindrical tube 421 , and the sealing sleeve 4241 is rotated, and the sealing sleeve 4241 is fixed on the cylindrical tube 421 through the threaded column 4242 .

[0056] See also Figure 1 , Figure 5 and Figure 7 The heat curing molding device for cold shrink accessory products for busbar also includes an embracing unit 3, two of which are symmetrically connected to the two lifting units 2, and the embracing unit 3 includes a strip plate 31 arranged between the two lifting units 2, and molding templates 32 are installed at the front and rear ends of the strip plate 31. The lifting plate 23 is fixedly connected to the corresponding molding templates 32, and the upper ends of the two molding templates 32 located above are symmetrically installed with injection tubes 33.

[0057] See also Figure 1 , Figure 5 and Figure 7 The embracing unit 3 also includes a heating plate 34 installed inside the molding template 32 and having an arc-shaped structure. The outer ring surface of the heating plate 34 is provided with heat insulation cotton 35, and the heat insulation cotton 35 is located inside the molding template 32.

[0058] See also Figure 2 , Figure 6 and Fig.11 The pushing assembly 445 includes a T-shaped plate 4451 slidably connected between the vertical sections of the cross through hole 443, the lower end of the vertical section of the T-shaped plate 4451 is located directly above the traction rope 4443, a return spring 4452 is installed between the lower end of the horizontal section of the T-shaped plate 4451 and the upper end of the sliding block 442, and the lower end of the horizontal section of the T-shaped plate 4451 is symmetrically provided with inclined surfaces front and back.

[0059] During specific operation, the injection tube 33 is connected to a container filled with insulating liquid silicone rubber, and the heating plate 34 is connected to an existing external power supply. When the sealing sleeve 4241 is sleeved on the cylindrical tube 421, the two bidirectional hydraulic push rods 22 are started, and the two bidirectional hydraulic push rods 22 drive the four molding templates 32 to move toward the two cylindrical tubes 421 respectively through the four lifting plates 23 until the opposite ends of the molding templates 32 on the upper and lower sides are tightly attached. At this time, the two molding templates 32 located on the outer side of the cylindrical tube 421 are respectively attached to the sealing ring 4 22 and the sealing sleeve 4241 are tightly attached, so that the space between the cylindrical tube 421 and the corresponding two molding templates 32 is in a sealed state. The four molding templates 32 move relative to each other and drive the two strip plates 31 to move relative to each other. The strip plate 31 located on the upper side pushes the T-plate 4451 during the downward movement. The lower end of the T-plate 4451 pushes the traction rope 4443. The traction rope 4443 is forced to drive the corresponding two positioning rods 4441 to move closer to each other, and the two positioning rods 4441 gradually move closer to each other. The two connecting springs 4442 are pulled away from the two cylindrical tubes 421 to avoid affecting the close contact of the two molding templates 32, thereby ensuring the integrity of the subsequent insulating tube molding. The T-plate 4451 continues to move downward and pushes the positioning column 448 through two inclined surfaces. The positioning column 448 is rotated by the two rotating plates 447. When the upper end of the T-plate 4451 moves to the lower end of the positioning column 448, the rotating plate 447 drives the positioning column 448 to reset through the torsion spring, thereby facilitating The T-plate 4451 is limited in the up and down directions by the locking column 448 to prevent the T-plate 4451 from being reset while the two strip plates 31 are reset, thereby avoiding scratches on the surface of the molded insulating tube. Subsequently, the insulating liquid silicone rubber is injected into the space around the two cylindrical tubes 421 through multiple injection tubes 33. When the space between the cylindrical tube 421 and the upper and lower molding templates 32 is filled with the insulating liquid silicone rubber, the heating plate 34 is started to heat and cure the insulating liquid silicone rubber.

[0060] After the heating plate 34 is heated for a period of time, the heating plate 34 is stopped, and the two bidirectional hydraulic push rods 22 drive the four molding templates 32 to separate and reset from each other through the four lifting plates 23. At this time, the insulating tube is thermoset and formed, and then the limit plate 434 is rotated to release the limit on the limit opening 432 on the left, and the sliding plate 433 is pushed. The sliding plate 433 moves to the limit opening 432 on the right, and then the limit plate 434 is matched with the limit opening 432 on the right. While the sliding plate 433 moves, the two pushing tubes 4231 are pushed. The two pushing tubes 4231 slide in the corresponding waist-shaped holes 4236 through multiple cylindrical rods 4234 and drive the corresponding moving plate 4235 to move toward the axis direction of the cylindrical tube 421. The moving plate 4235 drives the two blocking strips 4238 to separate from the corresponding rectangular through holes through the connecting strip 4237, and then the air pump is started, and the air pump passes the two intake pipes 4232 is injected into the two pushing tubes 4231, and then injected into the cylindrical tube 421 through the air outlet 4233 on the pushing tube 4231. The air is blown from the rectangular through hole to the inner side of the formed insulating tube, which can not only realize the rapid cooling of the thermosetting insulating tube, but also separate the insulating tube from the surface of the cylindrical tube 421, so as to facilitate the removal of the insulating tube from the cylindrical tube 421, and avoid the insulating tube from being deformed and unable to be restored due to excessive force applied during the removal process due to excessive adhesion, thereby ensuring the integrity of the removed insulating tube, and then remove the sealing sleeve 4241 from the cylindrical tube 421, and then remove the two insulating tubes from the two cylindrical tubes 421, and finally manually rotate the positioning column 448 to release the limit on the T-plate 4451, and the T-plate 4451 is reset by the reset spring 4452, and then repeat the previous insulating tube molding steps until the required number of insulating tubes are formed.
