Description
Technical field
The utility model relates to transformer station flexible bus and distribution line technical field.
Background technology
In the voltage power distribution equipments at different levels of transformer and distribution station, engine, transformer are called to bus with the wire that various electrical equipment is connected.Bus is divided into hard bus and soft bus by structure, and hard bus is mainly used in indoor, and soft bus is mainly used in being connected between transmission line and transformer, is mainly used in outdoorly, is the outdoor aerial aluminium stranded conductor, flexible.In transformer station's line construction process, the sag of adjusting soft bus is to set up, safeguard the indispensable routine work of distribution line, the factors such as the distance between the size of sag and transmission line and transformer, line voltage distribution, weather are relevant, the excessive or too small safe operation that all can affect circuit of sag.When sag is excessive, can not guarantee the safe distance of soft bus to ground, especially during summer high temperature, soft bus can extend because of heat expansion, and sag is larger, during strong wind, also may cause short circuit accident, when sag was too small, the stress that soft bus bears was excessive, when temperature is too low in the winter time, soft bus shrinks, and likely causes the broken string accident.
In the transformer station flexible bus erection process, traditional construction method is: first use soft bus one end insulator to fix in bus steelframe structure one side, the other end is fixed in the other end insulation of bus steelframe structure after adjusting sag, adjust sag and adopt the method for marking, this method usually needs unwrapping wire, stringing several times to adjust sag, working strength is large, and is difficult to the sag adjustment of bus to satisfactory standard; And in day-to-day operation, soft bus there will be the inconsistent situation of sag, if processed not in time, will cause transformer station or line fault, therefore in the regular maintenance process, need to process in time the inconsistent soft bus of sag, and owing to fixing at soft bus two ends, can not adjust, to the inconsistent soft bus of sag occurred, can only change, change and need to have a power failure, cause the operating time long, working strength is large, the waste material.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, convenient and reliable transformer station flexible bus sag adjusting device, can adjust in time, fast, safely the sag of soft bus, reach satisfactory standard, reduced the replacing number of times, laborsaving, save time, economize material.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of transformer station flexible bus sag adjusting device, comprise insulator and the strain clamp of being located at insulator one end, the other end of described insulator is provided with the stroke adjustment bolt that can be connected with pylon.
Be preferably, described strain clamp is connected with insulator by simply connected bowl head.
Be preferably, described insulator is insulator string.
Be preferably, described stroke adjustment bolt is U bolt, is connected with this insulator by the connecting ring of being located at insulator one end.
Be preferably, described stroke adjustment bolt is provided with connector, and this connector is connected with the stroke adjustment bolt by through hole provided thereon.
The beneficial effect that adopts technique scheme to produce is: the utility model is simple in structure, convenient and reliable, can adjust in time, fast, safely the sag of soft bus, reach satisfactory standard, reduced the replacing number of times, laborsaving, save time, economize material, reduce the working strength of setting up with regular maintenance, reduce line fault, reduce the economic loss of country and enterprise.The utility model is not only applicable to the adjusting of transformer station flexible bus sag, is applicable to the adjusting of little span circuit (being less than 50m) sag yet.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: the 1-strain clamp; 2-simply connected bowl head; The 3-insulator; The 4-connecting ring; 5-stroke adjustment bolt; The 6-connector; The 7-nut.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the transformer station flexible bus sag adjusting device, comprise insulator 3 and the strain clamp 1 of being located at insulator 3 one ends, and the other end of described insulation 3 is provided with the stroke adjustment bolt 5 that can be connected with pylon; Described strain clamp 1 is connected with insulator 3 by simply connected bowl 2; Described insulator 3 is preferably as insulator string; Described stroke adjustment bolt 5 is preferably U bolt, is connected with this insulator 3 by the connecting ring 4 of being located at insulator 3 one ends; Described stroke adjustment bolt 5 is provided with connector 6, and this connector 6 is connected with stroke adjustment bolt 5 by through hole provided thereon.
In concrete line construction process, an end that the utility model is provided with to strain clamp 1 is connected with soft bus, connector 6 on U bolt is fixedly linked with pylon, connector 6 can directly be welded on pylon, also two through holes can be set on connector 6, adopt bolt that connector 6 and pylon are fixed together, the two ends of U bolt are all with nut 7, can regulate the sag of soft bus, reach and meet the requirements, because power system security has a big risk, in the specific implementation, for guaranteeing power system security, at the two ends of U bolt, all adopt double nut 7 fixing, adopt again split pin locking nut 7.In the operating repairs process, when the sag of soft bus is undesirable, also can pass through adjusting nut 7 in the situation that do not cut off the power supply, make the sag of soft bus reach requirement.
The utility model is simple in structure, convenient and reliable, can adjust in time, fast, safely the sag of soft bus, reach satisfactory standard, reduced the replacing number of times, laborsaving, save time, economize material, reduce the working strength of setting up with regular maintenance, reduce line fault, reduce the economic loss of country and enterprise, be particularly suitable for the adjusting of transformer station flexible bus, little span circuit (being less than 50 meters) sag.
