Embodiment
Embodiment below in conjunction with description of drawings the utility model.
Like Fig. 1, Fig. 2, shown in Figure 3; The removable flameproof dry type transformer of the drive of the utility model comprises the flame proof housing; This flame proof housing comprise the casing 2 that surrounds by bellows and the case that is provided with through casing 2 two ends along flange 10 fixing be used for high-voltage connection end cap 4 and the low voltage terminal lid 1 that the high and low pressure lead-out wire is used, casing 2 is fixedly mounted on the removable base 7.The outer setting of casing 2 has web frame; This web frame comprise more than two the two ends case along between the flange 10, spacer sleeve is located at the support ring 5 that bellows outer surface and base 7 are connected, case along flange 10 and support ring 5 pass through be fixed with one along the reinforcement guardrail 6 that casing 2 axial restraints are connected on its two side external surface.The top of two support rings 5 is respectively arranged with hanger 11, between the top of two support rings 5, is fixedly connected with lifting brace 3.Inner circumferential at casing 2 is evenly equipped with bar shaped stiffener 9, and laying respectively at casing 2 both sides of straightway structure and the bottom axial restraint under the casing 2 in the inboard of casing 2 has flute profile reinforcement 8.Two support rings 5 are connected with lifting brace 3 and constitute the web frame main body of casing 2; The medial and lateral of casing 2 all are welded with reinforcing rib structure; Can well improve the axial bending strength of casing; And when lifting this body weight of transformer disperseed along flange and support ring by case, avoided compressive deformation in the middle part of the base; Bellows places in the support ring, and the two ends case is connected the two ends case along guardrail fixing between flange and two support rings and is integrally formed along flange, support ring, both improved the bulk strength of flame proof housing, has also played the effect of protection bellows simultaneously.Be used for the end that power set 15 that transformer moves place base 7, can operate easily.
In the present embodiment; Base 7 is mainly made by the square copper pipe or the channel-section steel of axial setting; Leave the gap between two copper pipes; The bottom of two support rings 5 radially convexes with contiguous block I, the II that is used to insert gap, base 7 middle part respectively downwards, and the sidewall that surface that the bottom of two support rings 5 is connected with the base steel pipe and contiguous block I, II are connected with the base steel pipe adopts welding manner to be fixedly connected with base 7 respectively.This Welding Structure is on support ring 5 and transverse plane that base 7 is connected and contiguous block I, II and vertical direction that base 7 is connected on all be welded with weld seam; Being stereochemical structure is connected; Strengthen the support of casing 2 so on the one hand, played the effect of reinforcing base on the other hand.
Present embodiment is to be example with two support rings, if the length of flameproof dry-type transformer is longer, and the also support ring of suit more than three at interval.
On the cross section of casing 2; The top semicircular in shape of casing 2 is the arc section structure; The both sides of casing 2 and casing 2 top arc sections are tangent to be vertical straightway structure; Bottom under the casing 2 is the straightway structure of level, and the connecting portion of the bottom under the both sides of casing 2 reach is the arc section structure of symmetry.The width of the flame proof housing of transformer reduces like this, is more suitable under the ore deposit transportation, and its explosion insulation performance is greatly improved, and can bear bigger destructive power than the flame proof housing of circular cross-section.
As shown in Figure 4; With high-voltage connection end cap 4 is example; The end of the high-voltage connection end cap 4 at the two ends of the flame proof housing of the utility model and low voltage terminal lid 1 is respectively arranged with the adpting flange 14 that is used to connect high pressure, low-voltage explosion-proof switch; Be respectively arranged with closure plate on the adpting flange 14, cable turnover line horn mouth 12 is arranged on the below of end cap 1 cavity on high-voltage connection end cap 4 and the low voltage terminal lid 1, and there is certain gradient the cavity below.This adpting flange 14 can directly dock with explosion-proof switch 13 forms the mobile substation; If do not take over control voltage flame proof switch 13; Can directly use as flameproof dry type transformer after covering closure plate, promptly same housing can be used in two types of products, has replaced the connected mode of counter flange of the prior art; Material cost and installation cost have not only been reduced; And shortened the distance of flame-proof switch day to the wiring end cap, and reduced flame-proof switch to be applied to the moment that terminals cover, solved the potential safety hazard that exists in the prior art.
