Description
Technical field
The utility model relates to a kind of improvement of lightning arrester, especially a kind of can waterproof and the waterproof lightning arrester of long service life.
Background technology
The electric power system of current China, particularly commonly uses waterproof lightning arrester in City Rail Transit System; Comprise body, disconnector, grounding terminal, high-voltage terminal; Described high-voltage terminal is connected to body one end; Described disconnector is connected to the other end of body; The other end of described disconnector is connected with grounding terminal; Described body is arranged at intervals with valve block, and described valve block is made up of ceramic material; The waterproof lightning arrester of this structure, easily aging, easy galvano-cautery, anti-ultraviolet property are poor, can not adapt to long-term work under the adverse circumstances such as acid, alkali, dirt, salt fog and humidity and water proofing property, poor insulativity.For this reason, we have developed a kind of energy waterproof and the waterproof lightning arrester of long service life.
Utility model content
The utility model object proposes a kind of energy waterproof and the waterproof lightning arrester of long service life to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of waterproof lightning arrester, comprises lightning arrester body, binding post, insulator support, heat explosion type come off device; Described binding post, comprises binding post body, stud, bluff body; Described binding post body is cylindric; Described stud is arranged on the lower surface of binding post body, and the diameter of stud is less than the diameter of binding post body; Described bluff body is that flat is arranged on the upper surface of binding post body; Horizontally on described bluff body be provided with connection bolt group; Described connection bolt group is used for connecing high-voltage line; Described stud screw thread is fixed on the upper surface of lightning arrester body; The described heat explosion type device that comes off is arranged on the below of lightning arrester body; Described insulator support is arranged on heat explosion type and comes off between device and lightning arrester body; Come off device, insulator support screw thread of one screw bolt passes heat explosion type is fixed on lightning arrester body, the outer end nut check of bolt; The outer end of described insulator support is provided with fixing hole, insulator support can be fixed by set bolt group.
Preferably, described lightning arrester body has silicon rubber to make, in cylinder, and on outer circumference surface level be evenly equipped with 3 groups of circular valve blocks.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Waterproof lightning arrester of the present utility model, product structure is simple, and volume is little, lightweight, and is provided with insulator support, and easy for installation, simple, installation cost is low; Valve block only needs 3 groups, and the height of lightning arrester body is short, can permanently effective work under the adverse circumstances such as acid, alkali, dirt, salt fog and humidity; The diameter of the bolt of described binding post is less than the diameter of binding post body, can effectively improve waterproof lightning arrester water proofing property and insulating properties during use.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the partial sectional view of waterproof lightning arrester of the present utility model;
Accompanying drawing 2 is the enlarged drawing of the binding post of waterproof lightning arrester of the present utility model;
Wherein: 1, lightning arrester body; 2, binding post; 3, insulator support; 4, set bolt group; 5, heat explosion type comes off device; 6, bolt; 7, nut; 8, connection bolt group; 11, valve block; 21, binding post body; 22, stud; 23, bluff body; 31, fixing hole.
Embodiment
As accompanying drawing 1,2 is depicted as a kind of waterproof lightning arrester of the present utility model, comprise lightning arrester body 1, binding post 2, insulator support 3, heat explosion type come off device 5; Described binding post 2, comprises binding post body 21, stud 22, bluff body 23; Described binding post body 21 is in cylindric; Described stud 22 is arranged on the lower surface of binding post body 21, and the diameter of stud 22 is less than the diameter of binding post body 21; Described bluff body 23 is arranged on the upper surface of binding post body 21 in flat; Horizontally on described bluff body 23 be provided with connection bolt group 8; Described connection bolt group 8 is used for connecing high-voltage line.Described stud 22 screw thread is fixed on the upper surface of lightning arrester body 1, and the diameter due to stud 22 is less than the diameter of binding post body 21, can infiltrate lightning arrester body 1 by anti-sealing during use from bolt 22 and the screw thread bearing of lightning arrester body 1; Described lightning arrester body 1 has silicon rubber to make, in cylinder, and on outer circumference surface level be evenly equipped with 3 groups of circular valve blocks 11; The described heat explosion type device 5 that comes off is arranged on the below of lightning arrester body 1; Described insulator support 3 is arranged on heat explosion type and comes off between device 5 and lightning arrester body 1; One bolt 6 is fixed on lightning arrester body 1 through come off device 5, insulator support 3 screw thread of heat explosion type successively, and the outer end nut 7 of bolt 6 is locked; The outer end of described insulator support 3 is provided with fixing hole 31, insulator support 3 can be fixed by set bolt group 4.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Waterproof lightning arrester of the present utility model, product structure is simple, and volume is little, lightweight, and is provided with insulator support, and easy for installation, simple, installation cost is low; Valve block only needs 3 groups, and the height of lightning arrester body is short, can permanently effective work under the adverse circumstances such as acid, alkali, dirt, salt fog and humidity; The diameter that the diameter of the bolt of described binding post is less than binding post body can effectively improve waterproof lightning arrester water proofing property and insulating properties.
Below be only embody rule example of the present utility model, protection range of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope
