Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, the utility model provide a kind of fast changeable 10kV protective device, including switchgear 1 with
And it is mounted on the device noumenon 2 on switchgear 1, device noumenon 2 is fixed on switchgear 1 by just tearing connector 12 open, due to opening
Cabinet about 30 years life cycles are closed, and protective device needs 12-14 replacement primary, therefore, device noumenon 2 needs to be flexibly connected,
So as to quick-detach fast when replacing device noumenon 2, simultaneously as existing rower advises 10kV protective device cabinet
Model, 1 cabinet door bore size of switchgear are applicable in all devices in frame mark, and there is no need to the sizes to device noumenon 2 to be adjusted.
There are three quick plug connecting pin 4, the sides of quick plug connecting pin 4 by the connection of backboard connecting line 3 for device noumenon 2
Side be provided with the matched quick socket connecting pin 5 in quick plug connecting pin 4, and quick socket connecting pin 5 passes through equipment
Connecting line 6 is connected with primary equipment 7, and the outside of backboard connecting line 3 and interfacility link 6 is arranged with connecting line protective case 11,
By the way that connecting line protective case 11 is arranged, backboard connecting line 3 and interfacility link 6 can be protected, and can be avoided electric leakage.
By setting quick plug connecting pin 4 and quick socket connecting pin 5 so that when replace protective device, be not necessarily into
Row secondary circuit disconnects line work by root core wire, it is only necessary to disassemble device noumenon 2 from 1 cabinet door of switchgear, then from fast
Quick plug connecting pin 4 is pulled out on fast socket connecting pin 5, completes the removal of old protective device, later by the fast of new protective device
Fast plug connecting pin 4 turns back in quick socket connecting pin 5, then completes the fastening of new protective device Yu 1 cabinet door of switchgear,
So that protective device replacement is more efficient, under traditional mode, completing a set of protective device replacement includes taking out stitches, being routed, connecing
The processes such as line and loop-around test need power off time about 5 hours, and under new model, directly pass through plug quick plug connecting pin 4
Device can be completed to replace, overall process time-consuming only 0.3 hour, while can reduce security risk of the device in maintenance, avoids
It mis-wired is in the presence of.
In addition, the specific structure of quick plug connecting pin 4 and quick socket connecting pin 5 is directed to, when current loop uses
2.5mm2 core wire, diameter is thicker after covering insulation is wrapped up, and the core wire number that can be arranged in the quick plug of equal volume is relatively
Few, 6~16 needle connectors, which can be selected, furthermore, it is contemplated that current loop will generate high voltage in the case of an open circuit can jeopardize maintenance
Personnel's personal safety should also select the side the CT socket end with anti-function of open to connect in addition to should have high voltage grade characteristic
Device；When current loop uses 1.5mm2 core wire, line footpath is relatively thin, the core wire number that can be arranged in the quick plug of equal volume
It is relatively more, 30~46 needle connectors can be selected, furthermore, it is contemplated that voltage circuit allows open running, with reference to existing terminal block
The circuits such as installation's power source, operation power and voltage circuit can be arranged in by design in the case where being sufficiently spaced-apart more dead end
With in a connector, it is contemplated that partial devices signal, open into etc. circuits use ± 24V light current, and circuit core wire quantity is more, can
This partial circuit is individually arranged in a connector.
The bottom end of quick socket connecting pin 5 is respectively connected with sliding block 8, be provided on switchgear 1 with the matched guide rail 9 of sliding block 8,
Sliding block 8 is fixed on the rail 9 by fixing bolt 10, by setting sliding block 8 and sliding rail 9, can make quick socket connecting pin 5
It moves on the slide rail, can be convenient the wiring connection of early period.
The above, above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although ginseng
The utility model is described in detail according to previous embodiment, those skilled in the art should understand that: it is still
