Abstract

The invention relates to a rack for a transformer. The rack is used for allowing the transformer to be arranged on a telegraph pole and a supporting pole. The rack comprises supporting frames on two sides and connectors used for enabling the two ends of the supporting frames on the two sides to be arranged on the telegraph pole and the supporting pole respectively. In particular, the rack further comprises an extending frame which is arranged at the top of the supporting pole and can extend in the arrangement direction of the supporting pole, wherein the two ends of each supporting frame are connected with the extending frame and the telegraph pole respectively through the corresponding connectors, and the lower end of the extending frame can be locked at the top of the supporting pole along with changing of the outer diameter of the supporting pole. According to the rack for the transformer, the original supporting pole does not need to be replaced, due to arrangement of the extending frame, installation intensity of the transformer is reduced, and meanwhile the rack is simple in structure, convenient to operate and very practical.

Description

A kind of placing frame of transformer

Technical field

the invention belongs to electric equipment field, be specifically related to a kind of for placing the placing frame of transformer.

Background technology

at present, for the placement of transformer, generally to be provided with special power distribution room, then establish according to actual needs the rack of differing heights, but, also there is another situation, that is exactly to be erected on outdoor electric pole, concrete employing two wire bars, one wire bar is for frame high-voltage line or electric wire, the second wire bar plays a part strut, simultaneously its highly general if after transformer is set up and the distance on ground to be greater than 2.5m just passable, that is to say, placing frame is for being erected at electric pole and strut by transformer, concrete placing frame comprises the support that is positioned at both sides, for the both ends that are positioned at both sides support are arranged on respectively to the connector on electric pole and strut, the base of transformer is connected on support, the both ends of support are connected on two wire bars by connector, but along with the transformation of environment, in the time the ground at electric pole place be set be raised, due to the limitation in height of strut, cause transformer apart from the distance on ground do not reach safe distance requirement, if change strut, its working strength is larger, simultaneously in the time that ground changes again, need to again change strut, thereby bring great inconvenience to the installation of transformer.

Summary of the invention

technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of placing frame of improved transformer is provided, and this placing frame, without changing original strut, reduces transformer installation strength, simultaneously simple in structure, easy to operate, and very practical.

for solving the problems of the technologies described above, the present invention takes following technical scheme:

a kind of placing frame of transformer, it is for being erected at electric pole and strut by transformer, this placing frame comprise be positioned at the support of both sides, for the both ends of both sides support are arranged on respectively to the connector on electric pole and strut, particularly, placing frame also comprise be erected at strut top and can along the setting party of strut to extend Extension support, connector is connected to the both ends of support respectively on Extension support and electric pole, and the bottom of Extension support can be locked in along with the variation of strut external diameter the top of strut.

according to concrete an enforcement and preferred aspect of the present invention, Extension support comprises that many rhizospheres are located at the periphery of strut and along the setting party of strut to the extension rod extending and be separately positioned on the first connecting portion and second connecting portion at the many upper and lower two ends of extension rod, wherein the both sides of the first connecting portion are connected with the end of both sides support respectively, and the second connecting portion is for being fixed on extension rod the upper end of strut.

preferably, extension rod has four, the rectangular periphery that is distributed in strut in horizontal cross-section of four extension rods, and four inner cavitys that form of extension rod, and the upper end of strut is arranged in cavity.

further, preferably, the second connecting portion comprises along any two relative edges of rectangular extension rod and is located at the connecting rod in cavity and is arranged on connecting rod below for four extension rods being locked in to multiple anchor ears of strut periphery, wherein connecting rod in the time that Extension support is erected on strut and the top of strut inconsistent.

in addition, being also provided with spacing anchor ear on electric pole, conflicts on spacing anchor ear in the end of both sides support.Prevent the downslide of placing frame, alleviate simultaneously and be arranged on the stressed of electric pole upper connector, extend the useful life of connector.

due to the enforcement of above technical scheme, the present invention compared with prior art tool has the following advantages:

the present invention, without changing original strut, by the setting of Extension support, reduces transformer installation strength, simultaneously of the present invention simple in structure, easy to operate, and very practical.

Brief description of the drawings

below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described in detail.

fig. 1 is that the master of placing frame of the present invention looks schematic diagram;

fig. 2 be in Fig. 1 A-A to enlarged diagram;

wherein: 1, transformer; 2, electric pole; 3, strut; 4, support; 5, connector; 6, Extension support; 60, extension rod; 60a, cavity; 61, the first connecting portion; 62, the second connecting portion; 620, connecting rod; 621, anchor ear; 7, spacing anchor ear.

Embodiment

as depicted in figs. 1 and 2, the placing frame of the transformer of the present embodiment, its for by transformer 1 be erected at electric pole 2 and strut 3, this placing frame comprise be positioned at the support 4 of both sides, for the both ends of both sides support 4 being arranged on respectively to the connector 5 on electric pole 2 and strut 3 and being erected at strut 3 tops and can be along the setting party of strut 3 to the Extension support 6 extending.

in this example, transformer 1 is erected on both sides support 4, electric pole 2 and strut 3 are respectively the length bar of cylindricality, support 4 opposing parallel settings, and support 4 is always in level, and connector 5 adopts common bolt and bracing piece respectively the two ends of support 4 to be connected to electric pole 2(stock) and Extension support 6 on, simultaneously, the height of Extension support 6 arranges according to actual dimensional requirement, and Extension support 6 can be locked in along with the variation of strut 3 external diameters the top of strut 3.

concrete, Extension support 6 comprises that many rhizospheres are located at the periphery of strut 3 and along the setting party of strut 3 to the extension rod 60 extending, and be separately positioned on the first connecting portion 61 and second connecting portion 62 at many extension rods two ends Shang Xia 60, in this example, extension rod 60 has four, the rectangular periphery that is distributed in strut 3 in horizontal cross-section of four extension rods 60, and four inner cavity 60a that form of extension rod 60, the upper end of strut 3 is arranged in cavity 60a, the both sides of the first connecting portion 61 are connected with the end of both sides support 4 respectively, the second connecting portion 62 is for being fixed on extension rod 60 upper end of strut 3.
