Description
Technical field
The present invention relates to a kind of heavy current disconnecting switches.
Background technology
High voltage isolator, by the difference of its mounting means, can be divided into outdoor high-voltage isolating switch to keep apart with indoor high-voltage
Close.Outdoor high-voltage isolating switch refers to bear the effects such as wind, rain, snow, filth, condensation, ice and depth hoar, is adapted to mount to balcony and makes
High voltage isolator.By the difference of its insulation column structure can be divided into open side type disconnecting switch, queen post disconnecting switch, three
Pillar disconnecting switch.Wherein vertical space is used as the most exhausted of fracture at built on stilts bus by open side type disconnecting switch directly below
Edge, therefore, the obvious advantage having, it is simply that save floor occupying area, reduce to draw connecing wire, opening and closing state is the most clear simultaneously.
In the case of EHV transmission, after electric substation uses open side type disconnecting switch, the effect saved floor occupying area is the most notable.
General one group of disconnecting switch of two each installations before and after chopper, purpose is all intended to chopper and isolated from power,
Form obvious cut-off point；Because chopper originally uses oil-break, oil-break needs often maintenance, therefore two sides are just
There is obvious cut-off point, be beneficial to maintenance；Generally, outgoing line cabinet is to be powered downwards by switch cubicle from bus above,
Need one group of disconnecting switch to be intended to and isolated from power before chopper, but sometimes, after chopper, also have the possibility of incoming call, as
The counter of device such as counter by other loop is sent, capacitor are sent, therefore are also required to one group of disconnecting switch after chopper.Keep apart
Close and be mainly used to high voltage distribution installation to need the part having a power failure reliably isolate with live part, to ensure service work
Safety.The contact of disconnecting switch is the most open in atmosphere, has obvious cut-off point, and disconnecting switch does not has arc-control device, because of
This can not be used for cutting off load current or short circuit current, and otherwise under high pressure effect, cut-off point will produce strong electric arc, and be difficult to
Self-extinguish, in some instances it may even be possible to cause arcing, scaling loss equipment, jeopardize personal safety, here it is so-called " on-load draws disconnecting switch "
Major accident.
Current existing disconnecting switch structure is complicated, inconvenient operation, structural insulation poor effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of compact conformation, and insulation effect is good, convenient and reliable operation big
It is galvanically isolated switch.
For solving the problems referred to above, the present invention adopts the following technical scheme that a kind of heavy current disconnecting switches, including U-type groove steel,
Rotating shaft, ceramic leg and insulated sleeve, described U-type groove steel is located at two pieces, and described rotating shaft is arranged in the middle part of U-type groove steel, described pottery
Porcelain pillar is fixed on U-type groove steel, and described insulated sleeve is arranged in ceramic leg, and described insulated sleeve is provided with two, left side
Being provided with static contact in insulated sleeve, side insulation right sleeve pipe is provided with moving casing, described moving casing cuts with scissors with insulated sleeve
Connect, in described moving casing, be provided with moving contact, patch panel is installed outside described insulated sleeve, is provided with in the middle part of described rotating shaft
Support seat, described support seat is provided with insulated tension pole.
As preferably, described U-type groove steel is mutually permanently connected, and keeps Stability Analysis of Structures reliable.
As preferably, the rectangular setting in described insulated sleeve cross section, conveniently install, keep compact conformation.
As preferably, hinged with support seat bottom described insulated tension pole, keep convenient and reliable operation.
As preferably, described insulated tension pole top is hinged with moving casing, easily installs regulation.
The invention have the benefit that the U-type groove steel of setting keeps structural strength high, facilitate the peace of rotating shaft and ceramic leg
Dress, keeps compact conformation；The insulated sleeve arranged and insulated tension pole keep insulation effect good；The rotating shaft arranged keeps operation side
Just, easily it is adjusted；The patch panel arranged accesses electric wire in facilitating insulated sleeve, is connected with moving contact and static contact respectively,
Keep easy for installation.

It is provided with moving contact 7 in sleeve pipe 6, patch panel 8 is installed outside described insulated sleeve 4, in the middle part of described rotating shaft 2, is provided with support seat
9, described support seat 9 is provided with insulated tension pole 10.
Described U-type groove steel 1 is mutually permanently connected.
The rectangular setting in described insulated sleeve 4 cross section.
Bottom described insulated tension pole 10 with support seat 9 hinged.
Described insulated tension pole 10 top is hinged with moving casing 6.
The invention have the benefit that the U-type groove steel of setting keeps structural strength high, facilitate the peace of rotating shaft and ceramic leg
Dress, keeps compact conformation；The insulated sleeve arranged and insulated tension pole keep insulation effect good；The rotating shaft arranged keeps operation side
Just, easily it is adjusted；The patch panel arranged accesses electric wire in facilitating insulated sleeve, is connected with moving contact and static contact respectively,
Keep easy for installation.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, and any
The change expected without creative work or replacement, all should contain within protection scope of the present invention.
