[0024] like Figure 4-5 As shown, this example can achieve the effect of conveniently removing and replacing multiple coils 101 from multiple iron cores 106 .

[0025] Since the transformer includes a lower iron bar 105, a plurality of iron cores 106 are welded on the upper side of the lower iron bar 105 from left to right, a threaded column 103 is welded on the upper side of each iron core 106, an upper iron bar 102 is inserted into the plurality of threaded columns 103, each threaded column 103 is threadedly connected with a nut, an insulating sleeve 104 is sleeved on each of the iron cores 106, and each insulating sleeve 104 is sleeved with a coil 101, after removing the nut on the threaded column 103, the upper iron bar 102 on the plurality of threaded columns 103 can be removed, thereby removing the obstruction on the upper side of the plurality of coils 101, thereby facilitating the removal and replacement of the plurality of coils 101 from the plurality of iron cores 106.

[0026] like Figure 4-5 As shown, this example can achieve the effect of preventing the lower iron bar 105 from moving forward and backward relative to the support seat plate 201.

[0027] Since the lower iron bar 105 is placed on the upper side of the support seat plate 201, limiting edges 203 are provided at the front and rear ends of the upper side of the support seat plate 201, and the lower iron bar 105 is arranged between the two limiting edges 203. The support seat plate 201 is made of insulating material. The two limiting edges 203 can limit the movement of the lower iron bar 105 to prevent the lower iron bar 105 from moving forward and backward relative to the support seat plate 201.

[0028] like Figure 4-5 As shown, this example can achieve the effect of stably setting the lower iron bar 105 and the plurality of iron cores 106 on the support base plate 201 .

[0029] Since inclined surfaces 107 are provided on both sides of the lower iron bar 105, bosses 205 are fixed on both ends of the left and right ends of the support seat plate 201, two round rods 207 are provided on the left and right, and two square columns 206 are fixed on each round rod 207, and the square columns 206 are slidably connected to the corresponding bosses 205. The bosses 205 are threaded with pressing screws 204, and the two pressing screws 204 are respectively pressed on the outer sides of the two round rods 207. The pressing screws 204 are rotated to press the round rods 207, so that the round rods 207 slide inward through the two square columns 206 thereon, and then the two round rods 207 press the inclined surface 107 on the lower iron bar 105, and then the lower iron bar 105 is pressed tightly on the support seat plate 201, so that the lower iron bar 105 and multiple iron cores 106 are stably arranged on the support seat plate 201.

[0030] like Figure 4-5 As shown, this example can achieve the effect of preventing the support base plate 201 from blocking the heat dissipation oil and affecting the heat dissipation efficiency after being fixed in the housing 301 .

[0031] Since a plurality of through holes 202 are provided on both the front and rear sides of the support seat plate 201 from left to right, after the support seat plate 201 is placed in the shell 301, the heat dissipation oil in the shell 301 can flow from the through holes 202, so that the heat dissipation oil can flow freely, thereby avoiding blocking the heat dissipation oil and affecting the heat dissipation efficiency after the support seat plate 201 is fixed in the shell 301.

[0032] like Figure 4-7 As shown, this example can achieve the effect of conveniently supporting the seat plate 201 and fixing the plurality of coils 101 inside the housing 301 .

[0033] The support seat plate 201 is arranged on the inner bottom surface of the shell 301, and four threaded columns 2 304 are fixed on the inner bottom surface of the shell 301. The four threaded columns 2 304 all pass through the support seat plate 201, and each threaded column 2 304 is threadedly connected with a nut. The four threaded columns 2 304 facilitate the support seat plate 201 and multiple coils 101 to be fixed inside the shell 301. Heat dissipation oil can be placed in the shell 301 to facilitate heat dissipation of multiple coils 101.

[0034] like Figure 6-7 As shown, this example can achieve the effect of connecting a plurality of terminals 306 to the metal wires on the coil.

[0035] The upper side of the shell 301 is connected to a top plate 305 by screws, and a plurality of terminals 306 are arranged on the top plate 305. Ceramic insulating rings are arranged between the plurality of terminals 306 and the top plate 305. The plurality of terminals 306 can be connected to the metal wires on the coil, and the ceramic insulating rings prevent electricity from being passed between the plurality of terminals 306 and the top plate 305.

[0036] like Figure 6-9 As shown, this example can achieve the effect of determining the liquid level of the heat dissipation oil in the housing 301 according to the height of the prompt light 405 .

[0037] Since a column 401 is connected to the inner bottom surface of the shell 301 by screws, a stop pin 406 is inserted into the upper part of the column 401, a sleeve 402 is slidably connected to the column 401, two floats 403 are connected to the sleeve 402 by screws, the lower end of the pole 404 is welded to the sleeve 402, and a warning light 405 is arranged on the upper end of the pole 404. When insulating oil is loaded into the shell 301, the buoyancy of the float 403 makes the sleeve 402 move upward on the column 401, thereby driving the pole 404 and the warning light 405 to move upward. The liquid level of the heat dissipation oil in the shell 301 can be judged according to the height of the warning light 405, and the heat dissipation oil can be filled when the liquid level of the heat dissipation oil drops.

[0038] like Figure 6-7As shown in FIG. 10 , this example can achieve the effect of quickly switching the left and right positions of the housing 301 as needed.

[0039] Since two cylinders 303 are welded on the front and rear sides of the lower part of the shell 301, a stopper 302 is welded on the front of each cylinder 303, two cross bars 506 are arranged front and back, and two supports 508 are welded on each cross bar 506, and an inverted V groove 507 is arranged at the lower end of the support 508, and a vertical groove 504 is arranged at the upper part of the inverted V groove 507, and the four cylinders 303 are respectively inserted into the four inverted V grooves 507, and are located between the two supports 508 on the front side and between the two supports 508 on the rear side. Each of the four cylinders 303 is inserted horizontally with a stopper 505. Since both sides of the inverted V groove 507 on the support 508 are inclined, the gravity of the shell 301 is applied to the cylinder 303, so that the cylinder 303 is always at one end of the left and right ends of the support 508. The shell 301 can be pushed left and right to drive the four cylinders 303 to move left and right on the four inverted V grooves 507, so that the shell 301 can move left and right to quickly switch the left and right positions, and then quickly switch the left and right positions of the shell 301 as needed. The cylinder 303 is convenient to be put into the inverted V groove 507 from the vertical groove 504, and the stopper 505 can block the upper side of the vertical groove 504 to prevent the cylinder 303 from detaching from the inverted V groove 507 and the vertical groove 504. The stopper 302 on the cylinder 303 can prevent the cylinder 303 from moving forward and backward relative to the support 508 at will.

[0040] like Fig.10 As shown, this example can achieve the effect of adjusting the left and right position of the housing 301 over a wide range.

[0041] Since the transformer also includes a connecting bar 501, flat seats 502 are welded to the left and right ends of the connecting bar 501, and two screw sockets 503 are welded to each flat seat 502. The two ends of each cross bar 506 are respectively connected to the two flat seats 502 by transverse sliding. The front and rear sides of the flat seat 502 are threadedly connected with fastening screws, and the fastening screws are pressed on the corresponding cross bars 506. Screws can be inserted into the four screw sockets 503, so as to fix the transformer at a required position; the two cross bars 506 can move left and right on the two flat seats 502, thereby driving the four supports 508 to move left and right in a large range, thereby making the shell 301 move left and right in a large range, and adjusting the left and right position of the shell 301 in a large range.
