Abstract
An impulse voltage generator shell structure for outdoor use is a sealed cylindrical structure which is installed vertically and high in voltage withstanding grade and mechanical strength. A cylinder is formed by assembling U-shaped square blocks made of epoxy materials; the U-shaped square blocks are provided with edge ribs; and glass fibers for rigid connection are arranged on the outsides of the edge ribs along the square blocks. The cylindrical structure can be combined and installed on site, and the edge ribs along the square blocks are connected into a rigid whole by the glass fibers. The shell structure is simple and convenient in installation and detachment and beautiful in form, has no metal connectors, and meets requirements on insulation.
Description
Technical field
The utility model relates to a kind of outdoor impulse voltage generator shell mechanism, is specially the shell of the impulse voltage generator of outdoor operation use, belongs to power industry High-Voltage Electrical Appliances testing equipment technical field.
Background technology
High voltage electric equipment in the electric system is in operational process; except bearing long-term load voltage; also may bear in short-term thunderbolt voltage and the percussive action of switching overvoltage; in order to test insulating property or the protective value of this kind equipment under lightning voltage and switching overvoltage effect; need detect by test apparatus equipment; lightning impulse voltage ripple and operating impulse voltage ripple can utilize impulse voltage generator to produce; therefore, impulse voltage generator is one of major equipment of high-tension laboratory.General impulse voltage generator all is indoor use, but when the electric pressure of electric system arrives extra-high voltage, required voltage generator voltage 〉=4000kV, setting height(from bottom) 〉=the 15m of its equipment, particularly when the external insulation test of carrying out tower window clearance, the indoor type impulse voltage generator is just inapplicable, at this moment just needs the outdoor type impulse voltage generator.When impulse voltage generator uses out of doors, need be at shell of its outside increase, to guarantee that internal electric equipment is not subjected to wind and weather, simultaneously, this shell also needs high strength, the high class of insulation and lighter physics proportion, both reaches to tolerate high voltage, satisfies requirement of mechanical strength again, also help dismounting, convenient transportation and preservation.China's utility model patent " outdoor type impulse voltage generator curtain wall " (application number: 87201864; the applying date: 1987-02-10) disclosed insulation cover is a kind of cranberry glass; be embedded with the aluminium alloy ornamental strip in the outside of horizontal classification place; compress with the panel that insulate the viscose glue adhering and sealing and be screwed; but this glass structure is because of reason such as frangible; be unfavorable for dismounting and transportation; existing known protection outer cover also has the fiber glass epoxy of large scale structure; its weak point is a loss of properties on aging; physical dimension is big, is unfavorable for dismounting and transportation.
Summary of the invention
The purpose of this utility model provides and overcomes the deficiency that background technology proposes, and a kind of outdoor type impulse voltage generator shell mechanism is provided, and it is the shell mechanism of stiff case piecemeal assembling mode, this structure dismounting is easy, convenient transportation, form is attractive in appearance, and structural strength meets the demands and is ageing-resistant.
The technical solution of the utility model is: a kind of outdoor impulse voltage generator shell mechanism, be vertically arranged high voltage withstand class and the high O-ring tubular structure of physical strength, it is characterized in that: described cylinder cylindrical shell is assembled by the U type square that uses epoxy material to make, described U type square has the limit muscle, the muscle outside, limit between the square, the glass fiber that the effect of being rigidly connected has been arranged, its beneficial effect is: this cylinder-like structure can on-the-spot aggregate erection, be linked to be a rigid cylinder shape integral body by the limit muscle with glass fiber between the U type square, installation and removal are easy, form is attractive in appearance, and no metal connecting piece satisfies insulating requirements.
Description of drawings
Accompanying drawing 1 is the utility model embodiment U type square schematic appearance;
Accompanying drawing 2 is the connected mode synoptic diagram of unit block;
The impulse voltage generator schematic appearance that accompanying drawing 3 is assembled into for the stiff case piecemeal.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further, the mark in the accompanying drawing is as follows, in the accompanying drawing 1, and 1-U type square, 2-limit muscle, in the accompanying drawing 2, the 3-glass fiber, in the accompanying drawing 3,4-spares pressure ring, the 5-inlet/outlet.
With reference to accompanying drawing 1, shown U type square is that epoxy material is made, square is an arc, limit muscle 2 is arranged around it, about 15 meters of cylindric outdoor impulse voltage generator shell overall height among Fig. 3, its topmost circumference has metal to spare pressure ring 4, the bottom also has door 5, be used for operator's turnover, other parts all are to be assembled by U type square, the connected mode of each square promptly is with glass fiber 3 the limit muscle around the U type square 1 closely to be coupled together mutually as shown in Figure 2, is combined into required outdoor impulse voltage generator shell mechanism.
Because each U type square relative volume is less, be shaped or dismounting so can assemble at the scene, avoided this volume of whole Transporting big, lightweight object, dismounting is easy, and form is attractive in appearance, and structural strength meets the demands.
Claims (1)
1. outdoor impulse voltage generator shell mechanism, be vertically arranged high voltage withstand class and the high O-ring tubular structure of physical strength, it is characterized in that: described cylinder cylindrical shell is assembled by the U type square that uses epoxy material to make, described U type square has the limit muscle, there has been the glass fiber that is rigidly connected and acts in the muscle outside, limit between the square.
