Abstract
The invention relates to a bus grounding knife-switch interlocker. The bus grounding knife-switch interlocker comprises two locking plates, a crescent plate, adjusting bolts, a pull rod and a locking groove, wherein the two locking plates are arranged on bus knife-switch movable contact arm bases at two sides respectively; two ends of the pull rod are connected with the crescent plate and the locking groove through the adjusting bolts respectively; and the other side of the crescent plate is fixed on a transverse rotating connecting rod of a grounding knife-switch. Based on the original knife-switch design, the effective mechanical locking of a double-bus grounding device in a locking state on bus isolating switches at two sides can be thoroughly realized, accidents of mistakenly switching on the bus isolating switches and the bus grounding knife-switch are eliminated, and the interlocker has a high safety coefficient and a strong defense function.
Description
Technical field
The present invention relates to a kind of busbar grounding disconnecting link interlocking device.
Background technology
Busbar grounding side isolating switch can only be realized mechanical defence locking with body ground connection disconnecting link, but under the double bus scheme mode, the ground connection disconnecting link can not be realized no ground connection disconnecting link side bus isolating switch is realized mechanical latching simultaneously.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of busbar grounding disconnecting link interlocking device, to prevent the generation of misoperation fault.
In order to solve the problem that prior art exists, the technical solution used in the present invention is:
Busbar grounding disconnecting link interlocking device, include two latch plate, swing link, adjusting bolt, pull bar and locking groove, described two latch plate are installed in respectively on the two side bus disconnecting link acting arm bases, the two ends of described pull bar link to each other with locking groove with swing link respectively by regulating bolt, and the opposite side of swing link is fixed on the ground connection disconnecting link and laterally rotates on the connecting rod.
Advantage and effect that the present invention had are:
The present invention is on original disconnecting link design basis, can realize thoroughly that the double-bus earthing device forms the effective mechanical latching to the both sides bus isolating switch when blocking, eliminate that mistake is closed bus isolating switch and busbar grounding disconnecting link accident, coefficient of safety is big, the defence function is strong.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
Among the figure: latch plate 1; Swing link 2; Regulate bolt 3; Pull bar 4; Locking groove 5; Regulate bolt 6.
Embodiment
As shown in Figure 1, busbar grounding disconnecting link interlocking device of the present invention, include the locking groove 5 of latch plate 1, oval-shaped swing link 2, columniform adjusting bolt 3, columniform pull bar 4 and the flute profile of two cuboids, described two latch plate 1 are installed in respectively on the two side bus disconnecting link acting arm bases, and latch plate 1 is used to stop disconnecting link opening and closing.Described swing link 2 belongs to drive disk assembly, the one side is fixed on the ground connection disconnecting link and laterally rotates on the connecting rod, the opposite side of swing link 2 links to each other with an end of regulating bolt 3, the other end of regulating bolt 3 links to each other with an end of pull bar 4, the other end of pull bar 4 links to each other with an end of regulating bolt 6, and the other end of regulating bolt 6 links to each other with locking groove 5.Regulate bolt and be used to regulate the transmission stroke.Locking groove 5 is realized blocking function with latch plate 1.
