Abstract
The utility model relates to a three-phrase combined type arrestor, which comprises three arrestor units, wherein a wiring structure is led out from the middle of each arrestor unit, each wiring structure comprises a special wiring block and a special lead-out screw bolt, the special wiring block is embedded inside the arrestor unit, the special lead-out screw bolt is inserted into the special wiring block from the outer wall of the arrestor unit, and a gasket, a spring gasket and a screw nut are sequentially matched and arranged on the special lead-out screw bolt. The structure can be independently installed without installing a fixing plate in the middle, soft leads are used for connecting the arrestor units, the arrestor units can be flexibly arranged according to the engineering requirements when the installation space is saved, and great convenience is brought for the on-site installation work.
Description
Technical field
The utility model belongs to lightning arrester manufacturing technology field, relates to a kind of lightning arrester, especially a kind of novel three phase combined lightning arrester that is applied to 35kV and following electrical voltage system.
Background technology
Three phase combined metal oxide arrester (hereinafter to be referred as lightning arrester) is a kind of important protective device that traditional protection electric equipment is avoided the overvoltage infringement, to when phase-the ground overvoltage is protected, also the high voltage of phase-alternate generation is protected.Traditional lightning arrester generally is made up of four lightning arrester unit, and wherein three lightning arrester unit are upper unit, and a lightning arrester unit is a lower unit.Generally be fixed on upper unit on the mounting panel successively during integral installation, lower unit is fixed under the mounting panel, or four unit are installed on the mounting panel, traditional 35kV electrical voltage system lightning arrester map interlinking as shown in Figure 1 and Figure 2, wherein Fig. 1 is the yi word pattern mounting means, Fig. 2 is the Y-shaped mounting means, wherein, 1,2,3 is lightning arrester unit, top, and 4 is lightning arrester unit, bottom, and 5 is mounting plate.Fig. 3 is novel lightning arrester, and wherein, 6 is the lightning arrester unit, and 7 is novel connecting terminal.By Fig. 1, Fig. 2 as can be seen, the installation of traditional three phase combined lightning arrester needs bigger space, to the requirement of installation site, installing space than higher.The space requirement that the traditional mounting means of this kind is installed lightning arrester need bigger installing space, and the arrangement of lightning arrester can not change with the difference of project site characteristics than higher.Therefore, this conventional mounting mode is unfavorable for popularizing and development of the type lightning arrester.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of three phase combined lightning arrester is provided, and this kind lightning arrester improves the lightning arrester unit, proposes new wiring construction, reduce the floor space and the installing space of lightning arrester, make lightning arrester have mounting means flexibly.
The purpose of this utility model solves by the following technical programs:
The three phase combined lightning arrester of this kind, comprise three lightning arrester unit, wiring construction is drawn at middle part in each described lightning arrester unit, described wiring construction comprises the extraordinary tagblock that is embedded at inside, lightning arrester unit and draws bolt by the special type that lightning arrester unit outer wall is inserted in the extraordinary tagblock that described special type is drawn to cooperate successively on the bolt and is provided with packing ring, spring washer and nut.
Utilize flexible wire to connect between the wiring construction on the above-mentioned lightning arrester unit.
The utlity model has following beneficial effect:
Three phase combined lightning arrester of the present utility model make the lightning arrester unit can in the middle of mounting plate and independent the installation, utilize flexible wire that the lightning arrester unit is connected, when saving installing space, the lightning arrester unit can greatly facilitate on-site installation work according to the flexible arrangement that requires of engineering.
Description of drawings
Fig. 1 is the lightning arrester structural representation of the yi word pattern mounting means of prior art;
Fig. 2 is the lightning arrester schematic diagram of the Y type mounting means of prior art;
Fig. 3 is a structural representation of the present utility model.
Fig. 4 is the structure chart of novel connecting terminal
Wherein: 1,2,3 are existing lightning arrester unit; 4 are existing lightning arrester unit, bottom; 5 is mounting plate; 6 is the lightning arrester unit; 7 is binding post; 8 is extraordinary tagblock; 9 draw bolt for special type; 10 is nut; 11 is packing ring; 12 is spring washer.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 3, three phase combined lightning arrester of the present utility model, comprise three lightning arrester unit 6, draw wiring construction 7 at the middle part of each lightning arrester unit 6, wiring construction 7 comprises the extraordinary tagblock 8 that is embedded at 6 inside, lightning arrester unit and is inserted into extraordinary tagblock 8 interior special types by lightning arrester unit 6 outer walls draws bolt 9, and special type is drawn to cooperate successively on the bolt 9 and is provided with packing ring 11, spring washer 12 and nut 10.Utilize flexible wire to connect between the wiring construction 7 on each lightning arrester unit 6.
6 whens assembling in the lightning arrester unit, portion requires the position of outlet that the extraordinary tagblock 8 of particular design is installed within it, and draw bolt 9 places in the installation special type in advance flat head bolt is installed, behind lightning arrester unit 6 integral dies, take out flat head bolt, and the special type of packing into is successively in order drawn bolt 9, packing ring 11, spring washer 12 and nut 10.
Novel lightning arrester shown in Figure 3 is three middle structures that the tap wiring is arranged in lightning arrester unit then, this structure make the lightning arrester unit can in the middle of mounting plate and independent the installation, utilize flexible wire that the lightning arrester unit is connected, when saving installing space, the lightning arrester unit can greatly facilitate on-site installation work according to the flexible arrangement that requires of engineering.
In sum, the utility model carries out technological improvement with the lightning arrester unit, adopts special construction to draw wiring in the centre of lightning arrester unit, realizes also making it have mounting means more flexibly outside the defencive function that traditional lightning arrester has.
