Abstract
The utility model relates to a ground external insulation structure for a suspended lightning arrester. The ground external insulation structure comprises a connecting plate connected with the lightning arrester and a terminal plate for installation, and is characterized in that insulation pads with insulation effects are arranged between the connecting plate and the terminal plate. The ground external insulation structure not only guarantees ground insulation of the lightning arrester but avoids excessive increase of structure height of the lightning arrester, and is convenient to install.
Description
Technical field
The utility model relates to over the ground external insulation structure of a kind of suspended-type surge arrester, mainly is the insulation against ground problem of lightning arrester when solving the installation of on-line monitoring equipment.
Background technology
Because the Transmission Line Arrestor of voltage levels operation occasion is generally on the high mountain high tower, for Daily Round Check suitable difficulty is arranged, and adds the increasingly mature of on-line monitoring technique, nowadays begins the online monitoring equipment of large batch of installation at power transmission and transformation system.Need between lightning arrester and steel tower, install an insulation system additional when existing lightning arrester is installed online monitoring equipment, be generally a slice porcelain insulator sheet, increase simultaneously the series installation gold utensil.So not only greatly increase cost, and for some special erecting bed credit unions the installation of lightning arrester has been brought larger impact.
Summary of the invention
Technical problem to be solved in the utility model is the insulation against ground structure that a kind of lightning arrester of proposing for above-mentioned current condition carries, and has guaranteed insulation against ground by this structure lightning arrester, has reduced simultaneously installation difficulty.
The technical scheme that the utility model addresses the above problem employing is: this suspended-type surge arrester is external insulation structure over the ground, comprises the connecting plate that connects lightning arrester and the terminal block that usefulness is installed, and it is characterized in that being provided with between two boards the insulation cushion that plays insulating effect.
Described connecting plate can be connected with the lightning arrester body flange with bolt, and it can be connected together by upper terminal bolt and top terminal block and insulation cushion again, by described insulation cushion connecting plate and terminal block is insulated and opens.
Compared with prior art, the utility model has the advantage of: lightning arrester need not increase the insulation against ground that any annex just can be realized lightning arrester when installing; Simultaneously lightning arrester structure height increase is less, can satisfy the installation of more occasions.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Please refer to shown in Figure 1ly, the connecting plate 3 usefulness bolts 6 of this suspended-type surge arrester insulation against ground structure are connected with the flange of lightning arrester body 4, and bolt 7 is housed on the flange, are used for installing online monitoring equipment.And connecting plate 3 is connected with top terminal block 1 by upper terminal bolt 5.And for connecting plate 3 and 1 insulation of fishplate bar line are opened, between two plates, be provided with insulation cushion 2, and this insulation cushion 2 has can keep supplying the through hole that terminal bolt 5 passes, and terminal block 1, connecting plate 3 and insulation cushion 2 namely are connected together by upper terminal bolt 5.By this insulation cushion 2 connecting plate 3 and terminal block 1 and 5 insulation of upper terminal bolt are separated thus, thereby guaranteed the lightning arrester insulation against ground, also can reduce installation difficulty simultaneously.
Claims (2)
1. suspended-type surge arrester external insulation structure over the ground comprises the connecting plate (3) that connects lightning arrester and the terminal block (1) that usefulness is installed, and it is characterized in that: the insulation cushion (2) that has been provided with insulating effect between described connecting plate (3) and the terminal block (1).
2. suspended-type surge arrester as claimed in claim 1 external insulation structure over the ground, it is characterized in that: described connecting plate (3) is connected with lightning arrester body (4) flange with bolt (6), and described connecting plate (3) is connected together by upper terminal bolt (5) and top terminal block (1) and insulation cushion (2) again, by described insulation cushion (2) connecting plate (3) and terminal block (1) insulation is opened.
