The utility model discloses simple process, processing is convenient, and stability is strong, insulating effectual, is favorable to using widely.
Description
Technical field
The utility model relates to and belongs to field of electrical equipment, be specially a kind of Zhu for distribution substation can the Novel lightning arrester of permanently effective work under the adverse circumstances such as acid, alkali, dirt, salt fog and humidity.
Background technology
Because the reasons such as individual event ground connection, long line capacitance effect or load rejection can produce the higher temporary overvoltage of amplitude in electric power system, this overvoltage can cause the damage of electric equipment in electric power system.And the Main Function of lightning arrester in network system is restriction power network overvoltage amplitude, the equipment in electrical network is played to the object of overvoltage protection.And, owing to there being the equipment centralized configuration of different electric pressure, be more easily struck by lightning in power distribution station region in electric power system, cause the electric equipment of transformer station to break down, finally likely cause electrical network to be paralysed.
And lightning arrester great majority in the prior art all adopt copper sheet, iron plate in inside, be in operation due to a variety of causes, self explosion accident can be there is, explosion time easily forms very large threat to other equipment of surrounding and personal safety, meanwhile, due to traditional lightning arrester wildcard poor performance, when safeguarding, be difficult to change aging lightning arrester, and then have influence on the normal operation of relevant network system.
Utility model content
The technical problem that the utility model solves is to provide a kind of distribution substation lightning arrester, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of distribution substation lightning arrester, comprise lightning arrester body and case, wherein, on the porcelain body of described lightning arrester body, bottom is respectively arranged with upper connecting terminal and lower connecting terminal, and described case is sleeved on the outside of lightning arrester body, case bottom is threaded connection part and lower connecting terminal is fixed, top is then connected with lightning arrester body top by the resilient disc of a multiple contraction spring of band, simultaneously, one group of clamping shell fragment is also provided with on described case top, the flexibility of case on lightning arrester body can be realized by this clamping shell fragment and resilient disc to fix.
In the utility model, described case is ceramic case, and is also provided with one deck silicon steel bed course inside this ceramic case.
In the utility model, described resilient disc preferably adopts ceramic material resilient disc or polytetrafluoroethylmaterial material resilient disc.
In the utility model, the porcelain body outside of described lightning arrester body has the structure of gamp and umbellule, and gamp and umbellule are spaced, and the diameter of umbellule is 3/4 ~ 4/5 of gamp diameter.
In the utility model, the housing bottom of described case is provided with bracket stator, is connected by external bracket for convenient with disconnector.
Beneficial effect: the utility model structure is simple, rational in infrastructure, is separated lightning arrester and disconnector by insulator support by case, and meanwhile, case also can play the buffer action that necessarily insulate, if the blast that lightning arrester occurs can also be protected effectively to external world.In addition, due to lightning arrester body and case can separate machined shaping, compatibility is good, operations staff greatly can be facilitated to change lightning arrester body or case separately, ensure that the safe operation of system to greatest extent.
Accompanying drawing explanation
Fig. 1 is the generalized section of the utility model preferred embodiment.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See the preferred embodiment of a kind of distribution substation lightning arrester of Fig. 1, in the present embodiment, lightning arrester body 6 and case 7 is comprised, lightning arrester body 6 and case 7 separately shaping, wherein, case 7 is sleeved on the outside of lightning arrester body 6, is provided with one deck silicon steel bed course 5 inside it; And the porcelain body in lightning arrester body 6 centre position is provided with the spacer structure of gamp and umbellule, in this present embodiment, the diameter of umbellule is 4/5 of gamp diameter, effectively can improve stability and the insulation effect of lightning arrester body 6.
In the present embodiment, the upper and lower part of the connecting rod 3 of lightning arrester body 6 is then respectively arranged with upper connecting terminal 1 and lower connecting terminal 10, lower connecting terminal 10 and case 7 are threaded connection part 9 and are connected and fixed, and the housing bottom of case 7 is provided with bracket stator 8 is jointly connected with threaded connector 9; And be also provided with one group of clamping shell fragment 2 on the top of lightning arrester body 6 and be connected with case 7 except being provided with the resilient disc 4 of a multiple contraction spring of band.
Case 7 when mounted, is upwards set with by the present embodiment below lightning arrester body 6, then bottom it by fastening for threaded connector 9, namely its top fix voluntarily by resilient disc 4 and clamping shell fragment 2.
In the present embodiment; lightning arrester body 6 damages or explosion time; operation protection is carried out by case 7; also can provide certain insulation protection simultaneously; and when the lightning arrester body 6 damaged is changed, only need at case 7 bottom unscrewing screw connector 9, also will be separated with the disconnector that bracket stator 8 is connected while case 7 is taken off; now, then by lightning arrester body 6 change.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
