Abstract
The utility model relates to a high voltage isolating switch capable of being stably locked. The high voltage isolating switch mainly solves the technical problem that a locking member of a prior isolating switch cannot be replaced, so the clamping effect of a draw hook is reduced caused by the service lifetime extension. A locking member which can be clamped on the draw hook is fixed on an inlet insulating column of the high voltage switch. The locking member is hollow L-shaped, and includes a positioning part and a clamping part. The positioning part is fixed on an installation seat. The clamping part is in clamping cooperation with the draw hook. Because the high voltage isolating switch adopts the unique L-shaped locking member, and the locking member is detachably arranged on the insulating column, when the clamping effect is reduced caused by the service lifetime extension, the locking member can be replaced, and the clamping effect of the draw hook is maintained.
Description
Technical field
The utility model relates to a kind of isolating switch, refers in particular to a kind of stable high voltage isolator of locking.
Background technology
High voltage isolator is important device for switching in power plant and transformer station's electrical system, needs to support the use with primary cut-out, guarantees High-Voltage Electrical Appliances and the safety of device when service work, plays isolation voltage.
Existing high voltage isolator adopts drag hook to match with retaining structure and realizes limit effect, it is generally the mount pad processing retaining structure on insulated column, and mount pad and insulated column are non-dismountable, prolongation along with the operating period, retaining structure is easily impaired, cause the screens deleterious, thereby make troubles to use.
Summary of the invention
In order to overcome deficiency and the defective in background technology, the utility model provides a kind of stable high voltage isolator of locking, and the lock piece that solves existing isolating switch is non-exchange, extends the technical problem that easily causes drag hook screens effect to reduce along with using.
the technical solution of the utility model is: a kind ofly lock stable high voltage isolator, comprise base, the inlet wire insulated column, the outlet insulated column, the inlet wire terminal block, outlet terminal block and disconnecting link, described inlet wire insulated column, the outlet insulated column is provided with mount pad, described inlet wire terminal block, the outlet terminal block is individually fixed on mount pad, on described disconnecting link, drag hook is installed, be fixed with the lock piece with the drag hook clamping matching on described mount pad, described lock piece is hollow " L " type, comprise location division and screens section, described location division is fixed on mount pad, described screens section and drag hook consist of clamping matching.
Described disconnecting link also is provided with mounting panel and spring, and described drag hook is articulated on mounting panel, and mounting panel is provided with oval-shaped through hole, and described spring one end is connected with drag hook, and the other end is connected with mounting panel, and described drag hook is provided with the compressive plane that communicates with described through hole.
One end of described disconnecting link is articulated on the outlet terminal block, and the other end contacts with the inlet wire terminal block.
The beneficial effects of the utility model: the lock piece that adopts unique " L " type due to this high voltage isolator, this lock piece is dismountable to be installed on insulated column, along with the prolongation of operating period, when the screens effect reduces, just replaceable lock piece, thus keep the screens effect of drag hook.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, base 1, inlet wire insulated column 2, outlet insulated column 3, inlet wire terminal block 4, outlet terminal block 5, disconnecting link 6, mount pad 7, drag hook 8, lock piece 9, location division 91, screens section 92, mounting panel 10, spring 11, through hole 12, compressive plane 13.
Embodiment
The below is described further embodiment of the present utility model for accompanying drawing:
as shown in the figure, a kind ofly lock stable high voltage isolator, comprise base 1, inlet wire insulated column 2, outlet insulated column 3, inlet wire terminal block 4, outlet terminal block 5 and disconnecting link 6, described inlet wire insulated column 2, outlet insulated column 3 is provided with mount pad 7, described inlet wire terminal block 4, outlet terminal block 5 is individually fixed on mount pad 7, on described disconnecting link 6, drag hook 8 is installed, be fixed with the lock piece 9 with described drag hook 8 clamping matching on described mount pad 7, " L " type that described lock piece 9 is hollow, comprise location division 91 and screens section 92, described location division 91 is fixed on mount pad 7, described screens section 92 and drag hook 8 consist of clamping matching.According to such scheme, adopt the lock piece of unique " L " type due to this high voltage isolator, this lock piece is dismountable to be installed on insulated column, prolongation along with the operating period, when the screens effect reduces, just replaceable lock piece, thus keep the screens effect of drag hook.
In the utility model, described disconnecting link 6 also is provided with mounting panel 10 and spring 11, described drag hook 8 is articulated on mounting panel 10, described mounting panel 10 is provided with oval-shaped through hole 12, described spring 11 1 ends are connected with drag hook 8, the other end is connected with mounting panel 10, and described drag hook 8 is provided with the compressive plane 13 that communicates with described through hole 12.Adopt oval-shaped through hole 12, when operating a switch, increase lifting surface area, break quick, convenient.
In the utility model, an end of described disconnecting link 6 is articulated on outlet terminal block 5, and the other end contacts with inlet wire terminal block 4, increases the electric conductivity between disconnecting link 6 and terminal block.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
