Abstract
The utility model discloses a lightning arrester installed at the busbar side of a gas insulated switch cabinet. A bus connecting gas tank is installed at a bus connection position between switch cabinet bodies. A connecting bus and a copper contact seat are fixedly connected based on a bolt-nut structure between the adjacent switch cabinets. A groove is arranged at the upper portion of the copper contact seat; and a spring contact finger is arranged in the groove. An insulated casing tube is fixed in the bus connecting gas tank; the lower end of the insulated casing tube is fixedly connected with a copper shaft; and the copper shaft is embedded in the copper contact seat and is tightly connected with the spring contact finger. A lightning arrester body is installed above the insulated casing tube. Therefore, the lightning arrester and the bus can be effectively connected. The provided lightning arrester has the simple structure; the cost is low under the circumstances that the gas tightness of the switch cabinet is ensured; the space is utilized reasonably; and defects of difficult lightning arrester installation and large space occupation in the prior art can be overcome.
Description
Technical field
the utility model relates to a kind of lightning arrester, relates in particular to a kind of lightning arrester for gas insulation switch cabinet bus bar side.
Background technology
gas insulation switch cabinet is that high voltage device is sealed in the gas tank housing that is filled with SF6 gas pressure as bus, circuit breaker, isolating/grounding switch etc., and miniaturization is the important advantage of gas insulation switch cabinet, and its overall dimension is little, is convenient to arrange.But due to the restriction of its structure, generally in a switch cubicle, lightning arrester scheme can only realize in cable side.But, the bus that is arranged on top also can require to install lightning arrester, if realize bus bar side lightning arrester, by the voltage control on bus in safe range, the space that needs an independent switch cubicle or at least take a switch cubicle could be realized, if realize like this, certainly will improve by cost, loses the advantage of gas insulation switch cabinet miniaturization simultaneously, now need a kind of device badly when increasing bus bar side lightning arrester, can keep again the advantage of gas insulation switch cabinet miniaturization.
Utility model content
the utility model object is: a kind of lightning arrester of gas insulation switch cabinet bus bar side is provided, guaranteeing the bubble-tight while, the main bus bar in lightning arrester and gas tank is effectively coupled together, easy for installation and conserve space.
the technical solution of the utility model is:
a kind of switch cabinet bus side lightning arrester, comprise several lightning arrester bodies, described lightning arrester body is arranged on the top of insulating sleeve, the lower end of described insulating sleeve is fixedly connected with copper axle with bolt, described copper axle is nested in the copper contact seat being connected with bus, described switch cabinet bus side lightning arrester is arranged on bus and connects in gas tank, and one end of lightning arrester body is exposed to bus and connects outside gas tank.
preferably, in described copper contact seat, offer groove, groove has been nested with spring touch finger.
preferably, described insulating sleeve is fixed on the cover plate of described bus connection gas tank.
preferably, the quantity of described lightning arrester body is three.
the utility model has the advantages that:
one, the bus being connected between the cabinet that utilizes switch cubicle and cabinet connects gas tank, lightning arrester is set, and effectively bus is linked together, and without reinstalling a switch cubicle, has reduced cost again, and conserve space, guarantees the good air-tightness of switch cubicle.
two, copper axle is connected by spring touch finger with copper contact seat, because spring touch finger contact is many, the contact of each point is not high, and spring touch finger also has silver coating, has good polishing property, and compress variation is large, and contact stabilization is installed reliable.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the cutaway view of the utility model embodiment;
fig. 2 is the enlarged drawing of A in Fig. 1;
fig. 3 is the schematic diagram of the utility model embodiment.
wherein: 1. lightning arrester body, 2. insulating sleeve, 3. copper axle, 4. bolt, 5. copper contact seat, 6. spring touch finger, 7. bus connects gas tank, 8. cover plate, 9. bus, 10. nut.
Embodiment
embodiment:
as shown in Figure 1, Figure 2 and Figure 3, between two switch cabinet tops, with bus, connecting gas tank 7 connects, bus 9 between two cabinets is fixed together by bolt 4, nut 10 structures with copper contact seat 5, the lower end that is specially copper contact seat 5 offers screw, bolt 4 is through screw, bus 9 below copper contact seat 5, the both sides of bolt 4, then screw nut 10 bus 9 be fixedly connected with copper contact seat 5; The top of copper contact seat 5 offers groove, is provided with spring touch finger 6 in groove, and copper contact seat 5 has been nested with copper axle 3, copper axle 3 contacts with spring touch finger 6, and spring touch finger 6 skins are silver coating, and it has good polishing property, compressed shape variable is large, and contact stabilization is safe and reliable; The upper end of copper axle 3 is connected with insulating sleeve 2 by bolt 4, and bolt 4 is upward through insulating sleeve 2 walls; Insulating sleeve 2 inside are hollow, and lightning arrester body 1 is installed in it, and the upper end of insulating sleeve 2 is fixed on cover plate 8 by bolt nut structure, and lightning arrester body 1 exposes bus and connects gas tank 7.The quantity of the bindiny mechanisms such as lightning arrester body 1 insulating sleeve 2 suitable with it, copper axle 3 determines according to the quantity of bus 9, and it is installed in same bus and connects in gas tank 7; In switch cubicle shown in the present embodiment, be provided with three buses 9, the quantity of lightning arrester body 1 and bindiny mechanism is three.
while installing at the scene, between the bus between cabinet and cabinet, had copper contact seat to be connected, bus connects on the cover plate of gas tank and has been mounted with insulating sleeve, and insulating sleeve lower end has fixed copper axle.During installation, cabinet is arranged complete at the scene, and cabinet is connected with the bus between cabinet, and bus connects gas tank and is arranged on cabinet top, and copper axle inserts in copper contact seat, and is closely connected with spring touch finger; Sealing gas tank, connects the SF6 air release in cabinet in gas tank to bus, and bus has just been placed in SF6 gas completely like this, guarantees the air-tightness of switch cubicle; Finally lightning arrester body is packed in insulating sleeve; Copper axle couples together lightning arrester and bus by spring touch finger.
the utility model is simple in structure, can solve the shortcoming that prior art median generatrix side arranges lightning arrester difficulty, and effectively utilizes space, keeps the feature of gas insulation switch cabinet miniaturization; The contact point of spring touch finger is many, reliable and stable.
those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
