Detailed Description

As shown in the figure: the invention relates to a tower type comprehensive distribution transformer area which comprises a hollow tower body 1, a cross arm 2 arranged at the upper part of the tower body 1, a power transmission line 3 and a transformer 4, wherein the transformer 4 is arranged inside the tower body 1, a base 5 used for installing the transformer 4 is arranged at the lower part of the tower body 1, a window used for entering and exiting the transformer 4 is arranged at the lower part of the tower body 1, a sealing component 6 is arranged at the window, the transformer 4 is arranged inside the tower body 1 and positioned at the lower end of the tower body 1, and the power transmission line 3 is supported on the cross arm 2 and penetrates through the tower body 1 to be connected with the transformer 4. It should be noted that the tower body 1 is formed by rolling the steel plates, so that the whole body is attractive and elegant, the transformer is arranged in the tower body 1, the lightning, wind and rain weather is safe, the failure rate is reduced, and meanwhile, heat generated by the transformer 4 can be dissipated through the tower body 1.

In the embodiment, for the convenience of later maintenance, repair and part replacement, a wiring pipe 7 is arranged inside the tower body 1, two ends of the wiring pipe 7 are respectively provided with a wiring port i 701 and a wiring port ii 702, the upper part of the tower body 1 is symmetrically provided with a notch i 101 and a notch ii 102, the wiring port i 701 is opposite to the notch i 101 or the notch ii 102, and the wiring port ii 702 is opposite to a wiring terminal of the transformer 4; the cross arm 2 comprises a supporting part and an inserting part, wherein the supporting part is hollow, a wire inlet 201 is formed in the upper end of the supporting part, a threading hole 202 and a wire pressing assembly 203 are arranged in the inserting part, a notch III 204 is formed in the lower end of the inserting part, an ear plate (not marked in the figure) is arranged at the upper end of the inserting part, and the inserting part is connected with the notch I101 or the notch II 102. Electric power transmission line is through getting into cross arm 2 from cross arm 2 inlet 201 earlier to through threading hole 202 in line ball subassembly 203 department with from the electric wire connection that wiring mouth I701 came out, after the connection with the grafting portion of cross arm 2 insert notch I101 or notch II 102 can. When a certain section of wire is damaged, the wire can be replaced, splicing of parts is facilitated, and the power transmission line 3 is connected to the transformer 4 or the knife switch conveniently.

Furthermore, in order to prevent rainwater from entering the tower body 1 along the electric wire flow, an elastic rubber cylinder I205 is arranged in the wire inlet 201, when the electric wire penetrates into the elastic rubber cylinder I205, the elastic rubber cylinder I205 is expanded outwards to fill a gap between the elastic rubber cylinder I205 and the wire inlet 201, so that the rainwater is prevented from entering the supporting part of the cross arm 2 from the wire inlet 201, and the rainwater is prevented from entering the tower body 1. Further, the wire on the upper portion of the cross arm 2 shakes to cause a gap between the elastic rubber tube I205 and one side of the wire inlet 201 to be not completely sealed, and for further sealing, the phenomenon that the wire shakes between the elastic rubber tube I205 and one side of the wire inlet 201 to generate a gap to cause rainwater entering is avoided. A nylon block 206 and an elastic rubber tube II 207 are sequentially arranged in the threading hole 202 along the axial direction of the threading hole, and a drainage hole 208 is arranged at the bottom of the supporting part. The electric wire gets into 2 inside back rock amplitude reductions of cross arm, gets into through wires hole 202 after, by the centre gripping of nylon piece 206, then the electric wire is no longer rocked after nylon piece 206 almost, and II 207 of elastic rubber section of thick bamboo expand outward when the electric wire passes II 207 of elastic rubber section of thick bamboo this moment, and II 207 outside of elastic rubber section of thick bamboo are laminated with the electric wire is sealed, and II 207 outsides of elastic rubber section of thick bamboo are laminated with through wires hole 202, prevent that the rainwater from carrying out tower body 1.

In this embodiment, the base 5 is U-shaped, a slide 501 is disposed in a U-shaped groove of the base 5, a hollow steel pipe 502 is embedded in the upper end of the base 5, a groove 503 is disposed on the steel pipe 502, a locking plate 504 is inserted into the steel pipe 502, a support frame 8 is disposed at the bottom of the transformer 4, the support frame 8 includes a lower frame body 801, an upper frame body 802 sleeved on the lower frame body 801, and a manual jack 803, two ends of which are respectively connected to the upper frame body 802 and the lower frame body 801, the lower frame body 801 is provided with a slide rail 804 used in cooperation with the slide 501, and the upper frame body 802 is provided with a lifting lug (not labeled in the drawing) used in cooperation with the groove 503 on. During the use, wear out tower body 1 with the one end of support frame 8 earlier, be fixed in on support frame 8 with transformer 5, after the wiring finishes, in pushing into base 5 with support frame 8 and transformer 5 are holistic again. Then, the manual jack 803 is depressurized, the lifting lug of the upper frame body 802 moves downwards to be clamped into the groove 503, and finally the locking plate 504 is inserted into the steel tube 502 to integrally fix the support frame 8 and the transformer 5 on the base 5.
