Description
Technical field
The utility model relates to technical field of electricity, particularly relates to a kind of alternating-current high-voltage isolation switch.
Background technology
Isolating switch a kind ofly uses maximum electric equipments, and the principles and structure of itself is fairly simple, but due to use amount large, functional reliability requires high, all larger on the impact of the design of electric substation, power plant, foundation and safe operation.Traditional isolating switch, comprise base, two insulation columns, two contacts are (front, rear contact), plug-in strip, plug-in strip is provided with latch hook device (operation ring, latch hook and back-moving spring composition), front contact is provided with fore shaft, (latch hook automatic unlocking during separating brake of latch hook device energy automatic unlocking during point combination switch, latch hook auto lock during combined floodgate), but due to the difference of isolating switch mounting means and angle, when particularly installing perpendicular to ground, latch hook device is difficult to automatic unlocking, plug-in strip can not normal deciliter under these circumstances, even if inadequate deciliter is also easily caused potential safety hazard, affect normal power transmission.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of convenient execute-in-place, more safe and reliable alternating-current high-voltage isolation switch.
For achieving the above object, the utility model provides following technical scheme: a kind of alternating-current high-voltage isolation switch, comprise base, described base is provided with inlet wire insulation column and outlet insulation column, described inlet wire insulation column and outlet insulation column are respectively equipped with inlet wire contact and outlet contact, disconnecting link is provided with between described inlet wire contact and outlet contact, described disconnecting link is provided with latch hook device, described disconnecting link one end is articulated with on outlet contact, the other end is matched with inlet wire contact by latch hook device, described latch hook device is provided with operation ring and latch hook, operation ring and latch hook are coupled together by rivet by described latch hook device, back-moving spring is provided with between operation ring and latch hook, described disconnecting link is provided with 90 ° of spacing holes and 160 ° of spacing holes, and described outlet contact is provided with circular arc transition face.
The utility model is set to further: will operate ring design in described latch hook device and become semicircle, in described latch hook device, latch hook rear end is provided with projection, is connected with back-moving spring between described operation ring and latch hook.
The utility model is set to further: described disconnecting link profile design becomes channel steel type, and before described disconnecting link, contact-making surface is provided with splitter box.
The beneficial effects of the utility model are by adopting technique scheme, this alternating-current high-voltage isolation switch is provided with circular arc transition face by latch hook device and inlet wire contact, disconnecting link and outlet contact, 90 ° of spacing holes and 160 ° of spacing holes and outlet contact and matches and solve at plug-in strip under various mounting means, when particularly installing perpendicular to ground, latch hook device can unlock nimbly and freely and not bury potential safety hazard, safer, reliable effect.
Due to original isolating switch because operation ring is circular design, latch hook width is greater than operation ring nose width, and cause operation tool to withstand latch hook, back-moving spring does not stress, and causes latch hook not open, and cannot realize unlocking; The utility model will be by operating ring, and be designed to semicircle, in latch hook device, latch hook rear end is provided with projection, is connected with the structural design of back-moving spring between described operation ring and latch hook, and no matter switch is arranged on any angle, and latch hook device can realize automatic unlocking.
Further, because disconnecting link profile design becomes channel steel type, namely add the cross-sectional area of conduction, turn improve the intensity of disconnecting link; By being provided with splitter box, in contact-making surface many increases galvanic circle, disconnecting link through-current capability is stronger, and electric conductivity is better.
