Embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Be exemplary below by the embodiment being described with reference to the drawings, be intended to for explaining the present invention, and can not be interpreted as limitation of the present invention.
Describe the outdoor insulative switch pole according to the embodiment of the present invention in detail below with reference to accompanying drawing.
As described in Figure 1, according to the outdoor insulative switch pole of the embodiment of the present invention, comprising: Switch main body 4, lead assemblies 2, insulation shift fork 11, outlet terminal 14 and go out line component 15.
Specifically, in Switch main body, there is vacuum interrupter 6, be positioned at the first cavity 5 (for voltage transformer is installed) below of vacuum interrupter 6, be positioned at second cavity 17 on vacuum interrupter 6 and first cavity 5 right sides and be positioned at the 3rd cavity 12 (for current transformer is installed) on second cavity 17 right sides.
Lead assemblies 2 is connected with the left end of Switch main body 4 and is connected with the quiet end (being the left end of vacuum interrupter) of vacuum interrupter 6.For example, lead assemblies 2 is connected by locking nut 3 with vacuum interrupter 6.
Insulation shift fork 11 is installed in rotation in the second cavity 17 and is connected with the moved end (being the right-hand member of vacuum interrupter 6) of vacuum interrupter 6.
The left end of outlet terminal 14 is electrically connected with the moved end of vacuum interrupter 6 through the 3rd cavity 12.
Going out line component 15 is connected with the right-hand member of outlet terminal 14.
Taking one mutually as example, source current by cable 1 by current delivery to lead assemblies 2, lead assemblies 2 is fastenedly connected with the quiet end of vacuum interrupter 6, dividing potential drop is connected to the voltage transformer in the first cavity 5 simultaneously; Electric current is through the quiet end of vacuum interrupter 6, if vacuum interrupter 6 is closing state, electric current is from the quiet end moved end of flowing through, pass to outlet terminal 14, current delivery is provided line component 15 by outlet terminal 14, by the control insulation shift fork 11 of operating mechanism, the moved end of vacuum interrupter 6 and quiet end can be separated or close.If vacuum interrupter 6 is closing state, the electric current of exporting from the quiet end of vacuum interrupter 6 passes to out line component 15 through moved end to outlet terminal 14 and receives external cable 16, finally forms galvanic circle.
According to the outdoor insulative switch pole of the embodiment of the present invention, control the break-make of vacuum interrupter by insulation shift fork, compact conformation, operation expense be low, be not subject to running environment affect, can obviously reduce electric power facility investment and reduce defeated, feeder circuit loss.
According to an example of the present invention, described outdoor insulative switch pole also comprises fixing axle bed 10, and fixing axle bed 10 is located in the second cavity 17, and insulation shift fork 11 is installed in rotation on fixing axle bed 10.
Advantageously, the left end of outlet terminal 14 is connected with the moved end flexible electrical of vacuum interrupter 6.As shown in Figure 1, can adopt be flexible coupling 8 realize flexible electrical connect.
According to an example of the present invention, Switch main body 4 adopts epoxy resin one moulding by casting.
In other words, the manufacture of poured with epoxy resin solid insulation switch pole with install there is very strong technical and manufacturability, whole switch pole is separated by by outdoor epoxy resin injection-compression molding and surrounding environment, play protection, support and buffer action.
The solid outdoor insulative switch pole of poured with epoxy resin, comprises Switch main body 4 and is installed in the vacuum interrupter 6 that the level in Switch main body 4 is installed.Lead assemblies 2 is integral with Switch main body 4 pressure injections, and is fastenedly connected and conducting by clamp nut 3 with the quiet end of vacuum interrupter 6.Outlet terminal 14 and Switch main body 4 pressure injections are integral, and on Switch main body 4, form the 3rd cavity 12, for current transformer is installed.On Switch main body 4, be positioned at the first cavity 5 that vacuum interrupter 6 forms below, for voltage transformer is installed.
Vacuum interrupter 6 moved ends 8 are fastenedly connected and conducting by bolt assembly 9 with being flexible coupling, and fastening bolt assembly 9 is also connected with the moved end of vacuum interrupter 6 by the connecting hole on the inserts on insulation shift fork 11 simultaneously, and compression is flexible coupling 8.8 the other end of being flexible coupling is fastenedly connected and conducting by connecting bolt group and outlet terminal 14.The other end of outlet terminal 14 is connected and conducting by contact finger piece with the splicing ear going out in line component 15.Go out line component 15 and be fastenedly connected and sealed by the connection inserting part 13 on bolt group and Switch main body 4, going out the enclosure space forming between line component 15 and Switch main body 4 is the 3rd cavity 12 that current transformer is installed.Fixing axle bed 10 is arranged in the second cavity 17 by bolt group, and is fastenedly connected with the inserts on Switch main body 4.The rotating shaft of insulation on shift fork 11 axle bed 10 that is fixed is fixing, but insulation shift fork 11 can rotate around fixing axle bed 10.
Insulation shift fork 11, by the transmission of switch spindle driving member, rotates when switch spindle rotarily drives insulation shift fork 11, and the insulation shift fork 11 of rotation drives vacuum interrupter 6 moved end horizontal movements, makes vacuum interrupter 6 dynamic/static contacts divide, close.Thereby make whole pole loop separately or closedly complete the control to energized circuit.
According to the outdoor insulative switch pole of the embodiment of the present invention, adopt poured with epoxy resin all insulation equipment, the surrounding environment influence that is not subject in service, is not subject to condensation and filthy impact; Complete equipment has high electrical safety performance, and switch does not exist the possibility of blast when cut-offfing and being short-circuited the accidents such as electric current; Insulated part all adopts epoxy resin and the silicon rubber manufacture that hydrophobicity is good; Do not have the danger that gas and liquid are revealed.Can not give environment; Adopt epoxy sealing voltage transformer cavity, sealing is not affected by outside air; Adopt epoxy resin and go out line component, connecting the current transformer cavity that is sealed to sealing, not being affected by the external environment; Pole line adopts High-Voltage Insulation cable, has both increased insulation creep distance, also Convenient switch wiring; Electric current and voltage transformer secondary line are directly guided to secondary line in switch-box through pole installing hole, safe and reliable.
