Abstract
The utility model provides a removable composite zinc oxide surge arrester, which comprise a columnar composite outer casing oxide zinc surge arrester (8), a fixing plate (2) and a columnar insulated fixing support (1). An upper terminal of the insulated fixing support (1) is fixed with an upper conductive connecting piece (3) of a drop type fuse closing, and a lower terminal is fixed with a lower connecting piece (3) of a drop type fuse hanging leg. The upper end of the composite outer casing oxide zinc surge arrester (8) is fixed with an upper connecting piece (4) of a drop type fuse tube, and the lower end is fixed with a lower connecting hanging piece (9) of the drop type fuse tube. As the fuse tube of the drop type fuse is removed and instead of the connecting structure of the surge arrester, the composite outer casing zinc oxide surge arrester can be dropped by a link rod under the conditions of power on and tested. The composite outer casing zinc oxide surge arrester can be assembled by the link rod after the qualified testing. The utility model has reasonable structure, reliable contact and long service life.
Description
Technical field
The utility model relates to a kind of structure of combined oxidation zinc lightning arrester, a kind of detachable combined oxidation zinc lightning arrester.
Background technology
Combined oxidation zinc lightning arrester is the distribution system that is applicable to 10KV series; protection is sent out, converting equipment, avoids the infringement of lightning overvoltage, switching overvoltage and power-frequency overvoltage as the insulation of equipment such as transformer, electric rotating machine, cable, capacitor group, vacuum switch.Lightning arrester upper end connection electric transmission line, lower end ground connection.Suffer superpotential moments such as thunder and lightning at transmission line, valve block resistance descends rapidly, thunder and lightning is imported underground, makes protected electrical equipment exempt from overvoltage and damages.After the overvoltage, valve block resistance recovers automatically, and circuit recovers normal operation.This lightning arrester is fixed on the electric pole cross-arm with a fixed head usually, when regularly detecting, essential earlier with line outage it is pulled down, and having a power failure after qualified after tested installs again.
Summary of the invention
The combined oxidation zinc lightning arrester that the utility model need not have a power failure when being intended to propose a kind of regular the detection, a kind of detachable combined oxidation zinc lightning arrester.
This detachable combined oxidation zinc lightning arrester comprises composite sheath zinc oxide arrester and a fixed head of a column, and it also comprises the insulation fixed support (promptly removing the RW3-10KV fuse switch insulating support of fusion tube) of a column.Described fixed head is fixed on the support bracket fastened middle part of insulation.Insulate and fixing the last conducting connecting part of a fuse switch combined floodgate usefulness on the support bracket fastened upper terminal, fixing following company that a fuse switch hanging feet uses on the support bracket fastened lower terminal that insulate and conducting electricity fitting.A upper connector that fuse switch is effective is being fixed in the upper end of described composite sheath zinc oxide arrester, a following connection suspension member that fuse switch is effective is being fixed in the lower end of composite sheath zinc oxide arrester, the upper connector at composite sheath zinc oxide arrester two ends with is connected down last conducting connecting part that suspension member inserts insulation fixed support two ends and following conducting connecting part in.
This detachable combined oxidation zinc lightning arrester, owing to adopted the fusing organ pipe on the fuse switch laid down and changed the syndeton of making lightning arrester, during the maintenance test, can be under situation about not having a power failure, with link rod the composite sheath zinc oxide arrester is chosen down, test, with link rod it is installed again after the test passes.Rational in infrastructure, contact is reliable, and can use for a long time.
Description of drawings
Accompanying drawing 1 is the structure chart of this detachable combined oxidation zinc lightning arrester;
Accompanying drawing 2 is the structure chart of composite sheath zinc oxide arrester.
Embodiment
As depicted in figs. 1 and 2, this detachable combined oxidation zinc lightning arrester, composite sheath zinc oxide arrester 8 and a fixed head 2 of comprising a column, it also comprises the insulation fixed support (promptly removing the RW3-10KV fuse switch insulating support of fusion tube) 1 of a column.Described fixed head 2 is fixed on the middle part of insulation fixed support 1, fixing the last conducting connecting part 3 of a fuse switch combined floodgate usefulness on the upper terminal of insulation fixed support 1, fixing the following conducting connecting part 12 that a fuse switch hanging feet is used on the lower terminal of insulation fixed support 1, a upper connector 4 that fuse switch is effective is being fixed in the upper end of described composite sheath zinc oxide arrester 8, a following connection suspension member 9 that fuse switch is effective is being fixed in the lower end of composite sheath zinc oxide arrester 8, the upper connector 4 at composite sheath zinc oxide arrester 8 two ends with is connected down last conducting connecting part 3 that suspension member 9 inserts insulation fixed supports 1 two ends and following conducting connecting part 12 in.
When this detachable combined oxidation zinc lightning arrester uses, insulation fixed support 1 usefulness fixed head 2 is fixed on the cross-arm of electric pole, the upper terminal and the power transmission line of insulation fixed support 1 join, and the lower terminal of insulation fixed support 1 is connected with earth connection.Composite sheath zinc oxide arrester 8 rely on its upper connectors 4 and under be connected suspension member 9 and be installed on the fixed support 1 that insulate.During the maintenance test, can be under situation about not having a power failure, with link rod composite sheath zinc oxide arrester 8 is chosen down, test, to connect suspension member 9 down with link rod again after the test passes hangs on the following conducting connecting part 12 that the hanging feet of insulation on the fixed support 1 use, catch on the annulus 7 of composite sheath zinc oxide arrester 8 upper ends again with link rod, upper connector 4 is upwards pushed in the last conducting connecting part 3 of insulation fixed support 1 upper end, installing promptly, announcement finishes.
As shown in Figure 2, the rear end 6 and the upper terminal 5 usefulness nuts of the upper connector 4 of composite sheath zinc oxide arrester fix, and upper connector 4 is in lifts the position, can accurately be inserted into securely in the last conducting connecting part 3 of insulation fixed support 1 to guarantee it.The following connector 9 of composite sheath zinc oxide arrester 8 needs to rivet tightly with rivet 10, it can not be rotated, so that it remains on a suitable angle.
As shown in Figure 1, can also fix a heat explosion type disconnector 13 on the lower terminal of the insulation fixed support 1 of this detachable combined oxidation zinc lightning arrester.During installation, earth connection is connected with the lower terminal 14 that heat explosion type takes off device.When lightning arrester breaks down or degradation phenomena, be about to blast, jeopardize electric equipment and personal safety, and then when ground short circuit taking place causing the switch trip power outage, the heat explosion type disconnector can move in time, and this lightning arrester is rejected from transmission system.After the disconnector action, for the fault lightning arrester provides obvious sign, be convenient to find rapidly the fault point, maintenance is in time changed.
