Thered is provided by power supply system of electric traction.Tractive power supply system is primarily referred to as traction substation and contact net two large divisions.Electric substation
It is located near railway, the electric current that it will be sent here through high voltage transmission line from power plant, deliver on the contact net in railway overhead.Contact net
It is the equipment directly carrying electric energy to electric locomotive.Contact net is the equipment directly carrying electric energy to electric locomotive.Along railway
The both sides of line, sets up row's pillar, suspended on metal wire above, be contact net, and it can also be counted as electrified iron
The artery on road.Electric locomotive utilizes the pantograph of roof to obtain electric energy from contact net, and tractor-trailer train runs.
Anti-thunder circle, for the lightning protection of Traction Substation of Electric Railway outgoing, prevents sensing electric wave and invades power transformation
Institute, even destroys transformer and other electrical equipments.But current electric railway anti-thunder circle has the disadvantage in that
(1) coil uses single-screw not transposition structure, reduces circulation loss, can accomplish that low-loss runs, longtime running
Safe and reliable；(2) mechanical strength is big, when short circuit, will not destroy coil because of short-circuit force.
Utility model content
In view of the foregoing, the utility model is lost the low damage of high intensity little, that mechanical strength is big when providing a kind of operation
Consumption electric railway anti-thunder circle.
For reaching above-mentioned purpose, the utility model solves its technical problem and be the technical scheme is that
A kind of high intensity low-loss electric railway anti-thunder circle, including upper holder, lower fixed frame, be connected to described solid
The insulation lath that determine the some cross-over blocks between frame and lower fixed frame, described cross-over block stringed together, insulated tension pole, solid
The support insulator of bar type, support insulator mounting base and be arranged on described support insulator lower surface support insulator peace
Dress base；The quantity of described insulation lath is six and becomes even circumferential distribution；It is pressed with single-screw between described cross-over block to divide
The copper conductor of cloth；The two ends of described copper conductor are respectively by being welded to connect a terminal plate；Fixed frame includes upper holder
Annulus, in the upper support disk of fixed frame circle ring center, connect between fixed frame annulus and upper support disk
There is upper insulated tension pole installing plate；The quantity of described upper insulated tension pole installing plate is six and becomes even circumferential distribution；Described upper
The upper surface holding round dish is provided with an anti-thunder circle lifting boatswain chair；Described lower fixed frame includes lower fixed frame annulus, described lower fixing
The lower support disk of frame circle ring center, connects between described lower fixed frame annulus and lower support disk and has lower insulated tension pole to install
Plate；The quantity of described lower insulated tension pole installing plate is six and becomes even circumferential distribution；Described insulated tension pole is high-strength nylon
Rod, its quantity is six and is fixedly connected between described upper insulated tension pole installing plate and lower insulated tension pole installing plate；Described
Post insulator mounting base is fixedly connected on the lower surface of described lower fixed frame, and its quantity is three and becomes even circumferential to divide
Cloth；Described support insulator is arranged on described support insulator mounting base lower surface.
Its further feature is as follows:
Described support insulator mounting seat is square flange.
The material that fixed frame, lower fixed frame and support insulator mounting base use is non-magnetic material or iron material
Material.
Due to the utilization of technique scheme, the utility model compared with prior art has a following beneficial effect:
(1) coil uses single-screw not transposition structure, reduces circulation loss, can accomplish that low-loss runs, longtime running
Economic effect is obvious；
(2) mechanical strength is big, when terminal short-circuit, will not break up coil because of short-circuit force.
