Abstract
The utility model discloses a pressure equalizing cover. The pressure equalizing cover comprises a framework, and a plurality of D-shaped or O-shaped support frames which are vertically arranged around the framework and are horizontally arranged, wherein the outer surfaces of the plurality of support frames are connected with a plurality of metal tubes which are horizontally arranged and are uniformly distributed in parallel. According to the pressure equalizing cover, a structure that the metal tubes are arranged on the outer surfaces of the support frames replaces the conventional tortoise plastron structure, so that the production cost is reduced, and the assembly difficulty is reduced; and the metal tubes have high rigidity, high surface smoothness, no ponding, low wind resistance and obvious antioxidation effect, and is difficult to swing and deform, so that the pressure equalizing cover has good use performance and high economic value.
Description
Technical field
The utility model relates to a kind of power test part of appliance, particularly relates to a kind of grading shield.
Background technology
Employed grading shield when power equipment carries out withstand voltage, no partial discharge test is mainly the tortoiseshell structure at present, i.e. the planar tortoiseshell of assembling several balls on bracing frame.Its drawback of the grading shield of this form mainly contains: the tortoiseshell processing cost is high, difficult installs; Poor, the swing easily of the connective stability of tortoiseshell during use; In the tortoiseshell of bracing frame bottom ponding is arranged easily during outdoor use, influence test effect; Be prone to resistance during outdoor use and divide, the security and the stability of equipment is impacted; The easy oxidation in tortoiseshell surface etc.
The utility model content
The utility model technical matters to be solved provides a kind of easy installation, good stability, can avoid ponding, can reduce windage, the grading shield of safe, anti-surface oxidation.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of grading shield; Comprise skeleton, vertically install around the skeleton and be horizontal some D shapes or O shape bracing frame, be connected with some levels on said some bracing frame outside surfaces and install and the parallel metal tube that is uniformly distributed with arrangement.
As preferably, said metal tube is stainless-steel tube or aluminium-alloy pipe.
As preferably, the diameter of said metal tube is 10 to 30 millimeters, and the spacing between the adjacent metal pipe is 10 to 30 millimeters.
As preferably, said metal tube is welded on the bracing frame.
A kind of grading shield of the utility model adopts the metal tube arrangement architecture that is installed in the bracing frame outside surface to replace original tortoiseshell structure, has so promptly reduced manufacturing cost, has reduced assembly difficulty again greatly; And the metal tube good rigidly, be difficult for swing, distortion, surface smoothness high, can not form ponding, windage is little, antioxidant effect is obvious, so the usability of this grading shield is outstanding, economic worth outstanding.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is the structural representation of a kind of grading shield of the utility model.
Fig. 2 removes the vertical view behind the metal tube for Fig. 1.
Wherein, Reference numeral: 1 is skeleton, and 2 is bracing frame, and 3 is metal tube.
Embodiment
Disclosed all characteristics in this instructions, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this instructions (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
As depicted in figs. 1 and 2; A kind of grading shield of the utility model; Comprise skeleton 1, vertically install around the skeleton and be horizontal some D shapes or O shape bracing frame 2; Horizontal bracing frame 2 forms ring texture, is connected with some levels on some bracing frame 2 outside surfaces and installs and the parallel metal tube 3 that is uniformly distributed with arrangement.Skeleton 1 can be divided into the polylith process and assemble according to its volume size, so that transportation.Bracing frame 2 is connected on the skeleton 1 through bolt.
As depicted in figs. 1 and 2, metal tube 3 is stainless-steel tube or aluminium-alloy pipe in the utility model, and its surface oxidation-resistant effect is obvious, is designed to stainless-steel tube here.The diameter of metal tube 3 is 10 to 30 millimeters, and the spacing between the adjacent metal pipe is 10 to 30 millimeters, has so both reached and has all pressed effect preferably, has practiced thrift material again, has reduced its manufacturing cost; Office puts and requires can increase metal tube 3 diameters and reduce the spacing between the adjacent metal pipe when high.Here the diameter of stainless-steel tube is designed to 19 millimeters, and spacing is 17 millimeters.Metal tube 3 is welded on the bracing frame 2, installs very convenient.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
