Embodiment
As shown in Figures 1 to 9, the utility model comprises base 1, fixed head 14, upper cover 2, anti-theft bolt, theft proof padlock 5 summation current transformers 6, below in conjunction with accompanying drawing, the utility model is described.
As shown in Figures 4 to 6, base 1 entirety is the uncovered box structure in upper surface, can is welded and fixed and be formed by five block plates.On the front and rear wall of base, fixing respectively one first otic placode 11, the first otic placodes is square metallic plate, and the corner location of the first otic placode does fillet processing.The vertical setting of front and rear wall of each first otic placode and base, two first upper surfaces of otic placode and the upper surface of base are concordant.Two first otic placodes are symmetrical arranged, and on each first otic placode, are respectively equipped with two the second screwed holes 3.On the sidewall of the left and right of base, be fixed with respectively two the second otic placodes 12, the second otic placode is square metallic plate vertical setting of left and right sidewall with base, the edge of two second otic placodes does fillet processing, and on each second otic placode, is respectively equipped with two the second screwed holes 3.Be provided with the binding post that is provided for dodging step down side of one first elongated slot 13, the first elongated slots in the bottom of base.Be fixed with two fixed heads 14 in the bottom of base intracavity, fixed head is square metallic plate, can be welded in base intracavity.Two fixed heads, respectively across the two ends of the first elongated slot, are respectively equipped with the bottom surface of two the first screwed hole 15, the first screwed holes through base at the two ends of each fixed head.Be provided with one first through hole 141 at the center of each fixed head, when installation, by the bolt that coordinates with the first screwed hole by floor installation the low-pressure side at transformer, and ensure that the first through hole on two fixed heads is nested with on any two-phase binding post in step down side three-phase a, b, c, as shown in Figure 9, two fixed heads are nested with on the b of voltage device low-pressure side phase and c phase connection terminal by the first through hole.The binding post that is provided for entangling step down side of fixed head, prevents user's stealing from the binding post of the low-pressure side of transformer.The number of fixed head also can be three, and three fixed heads are nested with respectively on a, the b of voltage device low-pressure side, c three-phase terminal.Be respectively equipped with two second elongated slots 17 at the upper surface of base left and right sidewall, the corner location of each the second elongated slot does fillet processing.
As shown in Figures 1 to 3, at the dismountable upper cover 2 that is provided with in the top of base, as shown in Figure 7, Figure 8, upper cover is the cone-shaped metal part that lower surface is uncovered, on the sidewall of the front and back of upper cover, fix respectively a third ear plate 21, the planform of third ear plate is identical with the first otic placode, and two third ear plates are oppositely arranged and are used in conjunction with two first otic placodes respectively.On the sidewall of the left and right of upper cover, fixedly mount respectively one the 4th otic placode, the planform of the 4th otic placode is identical with the second otic placode, and two the 4th otic placodes are oppositely arranged and are used in conjunction with two second otic placodes respectively.Bottom at upper cover left and right sidewall is respectively equipped with two projections, and projection is for inserting the second elongated slot 17 in correspondence.The length and width size of upper cover and the length and width of base are measure-alike, when installation, two third ear plates are alignd with two first otic placodes respectively and the second screwed hole coaxial line on the second screwed hole and the first otic placode on third ear plate is arranged, now two the 4th otic placodes align with two second otic placodes.Owing to being respectively equipped with two the second screwed holes on the first otic placode and the second otic placode, two respectively of the numbers of the first otic placode and the second otic placode, are therefore fixed together upper cover and base by eight anti-theft bolts 4.Now, user is not easy upper cover to open, and then has avoided user's stealing from step down side binding post.For further preventing that user from prying open upper cover, on the second otic placode and the 4th otic placode, be also respectively equipped with lower lockhole 221 and upper lockhole 121, between upper lockhole and lower lockhole, be provided with a theft proof padlock 5.For avoiding sleety weather, rainwater accumulates the short circuit that causes circuit for a long time on transformer, is respectively equipped with a tank 23 in the both sides of upper cover, is beneficial to flowing of rainwater.
As shown in Figure 9, when use, first by bolt by floor installation on step down side, because bolt is positioned at base inside, can avoid user to destroy bolt base is removed.On the b phase that two fixed heads are nested with at step down side and c phase connection terminal, only expose the top of b phase and c phase connection terminal for stube cable.Difference stube cable La, Lb, Lc and Ln on four binding post a, b, c and n of step down side, for preventing the bending of cable, on the antetheca of base, be provided with four the second through holes 16, four the second through holes are corresponding with four binding posts respectively, and four cables stretch out through after the second through hole respectively.On cable La, Lb and Lc, be equipped with respectively a current transformer 6, current transformer and the electrical connection of kilowatt meter measuring device.Then by anti-theft bolt, upper cover and base are connected, now, four binding posts of step down side are limited in, in space that upper cover and base surround, can avoiding user directly from step down side stealing.When user when stealing, can monitor by current transformer from cable La, Lb and Lc, the current values that now current transformer records diminishes.
The no longer bending of step down side cable, has avoided the destruction of the insulating barrier that cable bending causes, and then provides guarantee for the safe operation of power circuit.Base is firmly connected with upper cover, has avoided user's dismounting, has damaged protector and the generation of stealing electricity phenomenon.
