Along with the acceleration of China's industrialization and urbanization process, environmental pollution presents ascendant trend.Various dunghills are deposited on insulator surface, have seriously influenced the cap and pin insulator insulation level that is used for transmission line, produce pollution flashover accident then, and transmission of electricity has brought serious hidden danger to power system security.
In order to improve the resistant insulation level of insulator, since nearly half a century, people have taked the increase creepage distance; At its surfaces coated water-repellent agent, improve contour structures design or the like measure, though obtained certain effect; But distance expection practical function hope preferably differs greatly, two, 30 years up to date, through the continuous accumulation of operating experience; It is found that two actual resistant insulation levels of umbrella anti-pollution type suspension disc insulator are preferable, have advantages of high practicability and be worth.
Because two beveled structure profiles are comparatively complicated, the shaping difficulty is higher, for a long time.Has only minority manufacturer production porcelain insulator; Higher in view of the porcelain insulator ageing rate, detect difficult in maintenancely, still cause a hidden trouble to safe operation; And toughened glass insulator is because forming technology is difficult to satisfy the contour structures needs; Nobody shows any interest in, even manufacture experimently, its profile also is difficult to satisfy the demand always.
Summary of the invention
To above-mentioned technological deficiency, the present invention proposes the insulator of a kind of pair of umbrella structure.
In order to solve the problems of the technologies described above, technical scheme of the present invention is following:
Two umbrella insulators comprise chapeau de fer, steel pin and glass workpiece, and said chapeau de fer glue is in the top of said glass workpiece; Be provided with endoporus in the middle of the said glass workpiece, said steel pin mucilage binding is in said endoporus, and said glass workpiece comprises umbrella and subumbrella; The said upper surface of going up umbrella is horizontal by 1 degree, and the said lower surface of going up umbrella is horizontal by 4 degree, and said subumbrella is arc structure; The radius of said subumbrella is 130mm, and the umbrella disk diameter is 300mm.
Further, said glass workpiece is one-shot forming.
Beneficial effect of the present invention is: the two umbrella plate shape suspension type glass insulators of anti-pollution type are on the basis of numerous anti-pollution type insulator structure designs; In conjunction with the newly-designed a kind of practicality resistant disc suspension glass insulator of (tempering) technology for making glass characteristics with good anti-pollution characteristic; The characteristics of this insulator are: utilize the wind of nature and the filthy deposit and a structure that stops the effective creepage distance of moist immersion of dripping of rain self clean surface; Thereby improve its resistant insulation level; Reduce the pollution flashover accident rate; Reach filthy regional transmission line security of operation, reliable, utilize improvement and steel process perfect of mould, make two key factors that improve insulator resistant insulation level---improve effective creepage distance and improve self cleaning capacity---through the structural design of profile; Combine dexterously, make this product have the practical function that use in filthy area.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Embodiment
To combine accompanying drawing and specific embodiment that the present invention is done further explanation below.
As shown in Figure 1, two umbrella insulators comprise chapeau de fer 1, steel pin 3 and glass workpiece 2; Said chapeau de fer 1 glue is provided with endoporus 10 in the top of said glass workpiece 2 in the middle of the said glass workpiece 2, and said steel pin 3 mucilage bindings are in said endoporus 10; Said glass workpiece comprises umbrella 5 and subumbrella 7, and the said upper surface 4 of going up umbrella is horizontal by 1 degree, and the said lower surface 6 of going up umbrella is horizontal by 4 degree; Said subumbrella 7 is arc structure, and the radius 9 of said subumbrella 7 is 130mm, and umbrella disk 8 diameters are 300mm.
Chapeau de fer 1 and steel pin 3 connecting through being connected gold utensil with lead with the iron tower of aerial condutor respectively as the two poles of the earth; It is complete insulator that glass workpiece 2 composes a rigid body as insulator by the high strength cement adhesive; Insulator is to connect bunchiness (the ball-and-socket socket of the bulb of steel pin and chapeau de fer) according to electric pressure; So the monolithic insulator is called the string element; Connection between two two umbrella insulators is that the ball-and-socket that the bulb of steel pin 3 is inserted in chapeau de fer 1 realizes that through 11 lockings of " R " type locking pin the characteristics of " R " locking pin are that locking is safe and reliable, and dismounting is convenient.The insulator string element has maximum twisting space, avoids the disappearance of losing insulator because of the jam of locking.
Glass workpiece 2 adopts common soda-lime-silica glass, and with a compression moulding, steel pin 3 adopts diameter 21mm45# steel, and chapeau de fer 3 adopts magnesium iron.Adhesive uses Portland cement, and mixing 6# sand is aggregate.
(1) one-shot forming technique
The structure of glass workpiece pressing mold is generally formed by upper and lower mould, finally forms glass workpiece profile and size, outside the factors such as equalization temperature except that mould and press time; Main key is the difficulty or ease of raising one's hat, and the stroke of mould is generally axially and the radially one-way movement of both direction, does comparatively difficulty of bidirectional-movement; Thereby limited the development of umbrella shape shape and size; Design generally can only be suppressed the structure of band rib under single umbrella and the umbrella, because two umbrella has been broken through the movement locus of original mould movement travel, must mould structure and movement locus be studied; Existing mould is done very big improvement, satisfied the requirement of two umbrella insulator glass spare once-forming moulding processs.
(2) glass workpiece steel process
Because two umbellate form contour structures and existing product design structure have very big-difference; Current technology and existing tempering apparatus can not meet the demands; The design is according to the tempering capacity factor of glass, the thickness of glass workpiece and shape, accounting temperature cooling rates such as wind-warm syndrome condition, air grid structure,, rotating speed etc.Newly-designed cooling quench device and rotating mechanism satisfy the tempering level and the product quality of this product fully.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the present invention's design; Can also make some improvement and retouching, these improvement and retouching also should be regarded as in the protection range of the present invention.
